Finding heterozygous FVL or PT20210 alone would not influence our management decision given the small association of questionable clinical significance with arterial thrombotic risk (see “Factor V Leiden or Prothrombin 20210 Mutation”) and aspirin would be our treatment of choice. Obesity; diabetes mellitus; cigarette smoking; hypertension; high low-density lipoprotein cholesterol; low high-density lipoprotein cholesterol; high lipoprotein(a), Family history of arterial problems in young relatives (<50 y of age), Atrial fibrillation–ECG, extended cardiac rhythm monitor, Patent foramen ovale–obtain cardiac echocardiogram: transthoracic with bubble study and Valsalva; if negative, consider transesophageal or transcranial Doppler. ), … Basic laboratory testing was normal. A 25-year-old woman presented to the emergency department with sudden-onset left flank pain. Evidence against association with PVD. Given his young age, PC, PS, and AT activities were tested and returned normal. We then considered the balance between her thrombotic and bleeding risk; she has markedly elevated APLA, is “triple positive,” and has no risk factors for bleeding. 0000023899 00000 n A. Alternatively, failure to identify a clinically significant thrombophilia could lead to inappropriate or inadequate treatment. Arterial embolism occurs when clots then migrate downstream, and can affect any organ. Also, the surgical method can be aimed at improving blood flow. This chapter reviews the basic pathophysiology of arterial thrombosis. An increasing body of evidence suggests the likelihood of a link between venous and arterial thrombosis. Blood 2020; 136 (13): 1487–1498. The clinical significance of the risk associated with heterozygosity is unclear, but given the small degree of it and the current lack of evidence on how heterozygosity may influence management, we do not test patients to identify heterozygous states. 0000028517 00000 n Second, the ability to identify or exclude a correlation is limited by low prevalence of both thrombophilias and truly unexplained arterial thrombosis. The minimum duration of anticoagulation therapy for arterial thrombosis is 7 days; consider additional therapy for 1 week for persistent clinical signs or partial/complete vessel obstruction on imaging. Thrombosis is the medical term for clot or the presence of a clot. Arterial thrombosis is rarer than either arterial embolus or venous thrombosis, is more likely to occur in the second or third trimester than in the puerperium, and commonly presents with persistent focal deficit, such as hemiparesis, without alteration of consciousness, seizures, or signs of increased intracranial pressure. The lack of association with AT deficiency may seem surprising, but the study did not report whether families had less prothrombotic AT deficiency because of a heparin binding defect, or the more prothrombotic type I, IIA, and IIC deficiencies.65, Given the association between PC and PS deficiency and limited data on AT deficiency and arterial thrombosis, we consider testing for these 3 deficiencies in patients younger than 55 years of age (with AT testing performed per guidelines to identify prothrombotic subtypes).66, APS is well-known to increase risk for arterial thromboembolic events. Treatment includes medicines that thin the blood or prevent clots, and using stents or catheters to open blocked vessels. Magnetic resonance imaging (MRI) scans revealed an acute infarct in the left middle cerebral artery distribution. In the absence of another contributing etiology, the patient’s event was classified as ESUS and continuation of antiplatelet therapy (aspirin 81 mg) for secondary prevention of ischemic stroke was recommended. 0000028130 00000 n The stroke literature has traditionally favored anticoagulation,87  although recent data suggest aspirin may have similar efficacy to anticoagulation with rivaroxaban, with less bleeding risk.88  This patient’s young age, absence of clinical signs or symptoms, and absence of family history made malignancy unlikely. A 39-year-old previously healthy man presented with sudden onset aphasia and right-sided weakness. The risk of recurrent arterial thrombosis after a COC-associated event is unknown, but given the patient had stopped her COC and had no other identifiable risk factors, anticoagulation was suspended and aspirin continued. Gregory Piazza, MD, MS 1; David A. Morrow, MD, MPH 2. %PDF-1.4 %���� Cocaine has multiple acute and long-term pro-thrombotic effects.27  Both tobacco, including smokeless tobacco,28  and marijuana29  can precipitate thromboangiitis obliterans (Buerger disease), which may manifest with arterial thrombosis. Because thrombotic events are frequently multifactorial, it is important to identify ALL potential atherosclerotic and thrombotic risk factors. Atherosclerosis is the development of plaques, or fatty hardenings, on the inner wall of an artery… 0000059993 00000 n 0000029039 00000 n Normal perfusion returned within 24 hours. Most cases are heterozygous but presumably there are a few homozygous included, with exact numbers not reported. 0000037249 00000 n Anticoagulants, antiplatelet medications, thrombolytics, and painkillers can be prescribed by doctors. The surgeon makes a cut in your neck to … 0000055112 00000 n We also review existing literature of the role of hypercoagulable disorders in arterial thrombosis and discuss our approach to thrombophilia workup in patients after an unexplained arterial event. 0000062975 00000 n An exception is young patients (<30 years) in whom there is concern for homocystinuria driven by other characteristic manifestations.

Arterial Thromboembolism. This classically occurs in the peripheral extremities, as in Raynaud phenomenon,52  but can also involve coronary, cerebral, and mesenteric arteries.53,54  Peripheral organ infarction (ie, kidney, spleen) can be the result of thromboembolism, which may arise from the aorta.55  Furthermore, it can be caused by vessel wall abnormalities such as dissection, aneurysm, and rare disorders including fibromuscular dysplasia and segmental arterial mediolysis. Although VKAs are Acute arterial thrombosis can cause myocardial infarction (MI), ischemic stroke, and acute limb ischemia (ALI). The management of an unexplained arterial thrombosis is challenging to generalize because it is case- and patient-specific. In the absence of indications for age-appropriate screening, no additional workup for malignancy was pursued. Data in adults indicate that understanding the pathomechanism and composition of arterial thrombosis is crucial for choosing the … When considering workup for an autoimmune and vasculitic etiology of an unexplained arterial thromboembolism, consider ordering erythrocyte sedimentation rate, C-reactive protein, ANA, rheumatoid factor, ANCA, and C3 and C4 complement. A clot from a deep vein usually doesn't move to the heart to cause a heart attack or to the brain to cause a stroke. 0000055135 00000 n Therefore, in the following 3 cases, we illustrate the application of our diagnostic framework and discuss management, both specific to the case and also as generalizable principles for clinical practice. It can involve medication, surgery, or both. While the treatment of a first unprovoked venous thrombosis in the setting of persistent antiphospholipid antibodies agreeably is long term anticoagulation at a target INR range between 2-3, treatment of arterial thrombosis however, has notoriously been more controversial … To help prevent swelling associated with deep vein thrombosis, wear them on your legs from your feet to about the level of your knees. The same lifestyle habits that can help treat coronary artery disease can also help prevent it from developing in the first place. Anticoagulation alone, antiplatelet therapy alone, or the combination can be used, but no consensus exists.94-96  We are aware of only 1 small randomized trial that compared treatment with aspirin 100 mg once daily alone to combination aspirin and vitamin K antagonist (target international normalized ratio, 2.0-3.0).97  Aspirin alone was associated with a higher incidence of stroke recurrence, with similar incidence of hemorrhagic complications. He was discharged from the hospital on aspirin. For deep vein thrombosis arterial clots, treatment options include the following: Anticoagulants/blood thinners: These medications can be injected or … Artery Thrombosis. Is there a suggestion of an infectious arteritis? Initial workup included an ECG and cardiac monitor during hospitalization, and neither identified an arrhythmia. Contribution: J.E.M. Then the goal becomes reducing your chances of deep vein thrombosis happening again.Deep vein thrombosis treatment options include: 1. 0000035694 00000 n Hemoglobin SC and S-β-thalassemia may have a benign clinical course before thromboembolism.40. To treat blood clots and prevent the damage they cause, doctors use anticoagulants, which are commonly called blood thinners, to decrease the clotting power of the blood and prevent growth of a clot. For example, when considering thrombosis in the cerebral vasculature, the location of the thrombus or ischemic territory can be suggestive of an embolic vs atherosclerotic etiology. History and initial workup revealed no obvious atherosclerotic or cardioembolic etiology. Therefore, as always with non-evidence-based antithrombotic management decisions, incorporation of patient-specific factors including bleeding risk, site of thrombosis, and patient preference, are of high importance. 0000039551 00000 n Table 4 lists seminal publications of the role of thrombophilias in arterial thrombosis. TTE with bubble study with Valsalva showed no evidence of right-to-left shunt, valvular disease, or intracardiac thrombus. Workup to exclude atherosclerotic and cardioembolic sources was performed and revealed no abnormality. 0000039483 00000 n The two vascular complications share several risk factors, such as age, obesity, smoking, diabetes mellitus, blood hypertension, hypertriglyceridemia, and metabolic syndrome. 0000028152 00000 n The primary team ordered a thrombophilia workup including FVL, PT20210, PC, PS, and AT activities; all returned without abnormality. 0000002868 00000 n MRI and magnetic resonance angiography of the brain and neck were unremarkable. Seminal publications on the association between commonly tested thrombophilias and arterial thrombotic events. The role of thrombophilias in arterial thrombosis is not well-defined, as opposed to venous thrombosis in which thrombophilias have been more extensively studied.56  The antiphospholipid syndrome (APS), however, has a well-documented increased venous and arterial thrombotic risk and is specifically addressed later. There is a well-documented correlation between systemic inflammatory disorders and increased arterial thrombotic risk,41,42  including sarcoidosis43  and systemic vasculitides such as antineutrophil cytoplasmic antibodies-associated vasculitis, large-vessel vasculitis, and Behçet’s syndrome.44  Therefore, a thorough evaluation for signs and symptoms of autoimmune disorders is warranted; nonspecific symptoms include generalized fatigue, arthralgias, fever, rash, and neuropathy, whereas more specific signs include palpable purpura, bruits, blood pressure discrepancies, or combined renal and pulmonary involvement. She remained off anticoagulation; aspirin was continued long-term. Arterial thrombosis results in ischemia, with serious systemic consequences, such as metabolic breakdown. The cause of the clot, if found, should be treated to prevent further problems. Blood pressure and screening for atherosclerotic risk factors (lipid panel, lipoprotein(a), hemoglobin A1c) were normal. 8.Discuss the essential differences between arterial and venous thrombosis, and how these differences influence treatment. Discussion with a subspecialist who cares for the affected organ is also recommended because the diagnostic approach to thrombosis in each organ system varies significantly. (10 marks) 9.Heparin was first used as an anticoagulant medication in 1935, and has been the first-choice drug for fast-acting intravenous anticoagulation ever since. She denied any prior medical problems. A 42-year-old woman developed stuttering onset over a few hours and then almost complete painless visual loss in her left eye, prompting presentation to the emergency department. Sickle cell disease is more commonly associated with stroke versus other arterial events. 0000062007 00000 n However, given limited data on how often these disorders might cause an unexplained arterial event, JAK2V617F and flow cytometry for PNH were sent and returned normal. Arterial thrombosis. Published products on this topic (41) Guidance. Certain disorders characteristically occur in a given arterial location, with cystic adventitial disease occurring in the popliteal artery and endofibrosis in the external iliac arteries.49  Extrinsic arterial compression, as in popliteal artery entrapment syndrome and thoracic outlet syndrome,50  can also occur. Imaging should be reviewed with a radiologist because diagnostic reports may lack necessary details. Vitamin K antagonists (VKAs) such as warfarin were the only orally ad-ministered anticoagulants for >60 years. 0000026981 00000 n In arterial thrombosis, the platelets and abnormalities of the vessel wall typically play a key role in vessel occlusion. Quit smoking 2. In a US registry of patients with coronavirus disease 2019 (COVID-19), thrombotic complications occurred in 2.6% of 229 non–critically ill hospitalized patients and in 35.3% of 170 hospitalized critically ill patients. Because there is an assorted list of factors that can precipitate an arterial event, we present a systematic diagnostic approach to ensure consideration of not only primary hypercoagulable disorders, but also pro-thrombotic medications or substances, vascular and anatomic abnormalities, and undiagnosed systemic disorders, such as malignancy and autoimmune diseases. Editors: Stephan Moll, MD and Sara Critchley, MS, RN. Another type of surgery for arterial thrombosis is called carotid endarterectomy, which you may have if you have had a blood clot in an artery in your neck (causing a stroke). ECG and cardiac monitor during 48-hour hospitalization were without arrhythmia, as was a 30-day Holter monitor after discharge. Unique management considerations in APS are discussed in case 2. Most known causes of thrombophilia are related to venous thromboembolic events, but there are several hypercoagulable conditions that cause both arterial and venous thrombosis. However, for secondary prevention in patients homozygous for FVL, homozygous for PT20210, double heterozygous for FVL and PT20210, or deficient in PC, PS, or AT, existing data suggest a stronger association with arterial thrombotic risk. Second, should this patient be placed on antiplatelet therapy, anticoagulation, or both? 0000038372 00000 n Leading a healthy lifestyle can help keep your arteries strong and clear of plaque. Although patients with renal infarction secondary to renal artery injury such as … H�b```f``;���� ��A��b�,X�\ ��k�20��b��4������7���%�xwL;��v��M�# ��M���dԤ;ޭ�٭Ԙ�yj�Z�PJ�� 1 Anticoagulation therapy is a cornerstone of thromboembolism prevention and treatment. Thrombosis, or clotting, is helpful in stopping the bleeding and healing the artery if it has a hole or is damaged. Contralateral retinal examination by the ophthalmologist was normal. No causative medications or other substances were identified and there were no symptoms or signs of a systemic disorder with normal physical exam (including a testicular exam), complete blood cell count (CBC), and liver enzymes. For example, if a laboratory abnormality suggests a thrombophilia, a patient may be inappropriately placed on lifelong anticoagulation without further workup, posing significant risk to the patient without proven benefit. Is atherosclerosis present or are there atherosclerosis risk factors? An arterial thrombosis is a blood clot in an artery. Access to the complete content on Oxford Medicine Online requires a subscription or purchase. The patient has a documented central retinal artery occlusion. Small association with MI, CAD, stroke; clinical significance unclear. Author Affiliations Article Information. 0000039859 00000 n She had been taking an oral contraceptive, drospirenone/ethinyl estradiol 3 mg/0.03 mg, since age 19. ���!�`\���1��\H����&. Atherosclerosis is the most common cause of major disability and death in the United States. 0000056276 00000 n When an arterial event occurs without clear provoking factors, a hematologist is often called upon to address 2 common questions. 117 0 obj << /Linearized 1 /O 120 /H [ 1735 900 ] /L 356564 /E 66215 /N 13 /T 354105 >> endobj xref 117 60 0000000016 00000 n No evidence-based guidelines are available so far to prefer one treatment approach to another. The most common blood thinners used today are heparin, low molecular weight heparin, and warfarin. Recanalization of the basilar artery is key to the successful treatment of basilar artery thrombosis and to improving its prognosis. Importantly, there is no evidence to support the superiority of anticoagulation, antiplatelet therapy, or the combination. Two randomized trials comparing rivaroxaban with warfarin showed excess thrombotic events, mostly arterial, in the rivaroxaban arms.98,99  Therefore, if anticoagulation is considered in APS, DOACs are best avoided pending further investigation. Whether there is benefit to testing for JAK2V617F or PNH in the absence of hematologic findings is unclear given limited existing data.37-39, Hyperviscosity, whether from erythrocytosis, leukocytosis, or excess plasma proteins (plasma cell disorder, cryoglobulinemia), can also increase arterial thrombotic risk. Deficits resolved following tissue plasminogen activator (tPA). An assessment of the patient’s symptoms as they correlate with the thrombosis location is also helpful. Evaluation for paroxysmal atrial fibrillation should include electrocardiography (ECG) and ambulatory cardiac rhythm monitoring, the optimal duration of which is debated10,14 ; 2 to 4 weeks is reasonable. Imaging can be reviewed with an expert radiologist for findings of vasculitis.45  Laboratory evaluation could include urinalysis and inflammatory markers (erythrocyte sedimentation rate, C-reactive protein). We conclude with 3 representative cases to both illustrate the application of the outlined diagnostic schema and discuss common management considerations, specifically the selection of anticoagulation vs antiplatelet therapy for secondary prevention. 0000025697 00000 n Strokes without identifiable causative etiology are referred to as cryptogenic, but a new term, embolic stroke of undetermined source (ESUS), was coined in 2014 to address a subgroup of cryptogenic strokes that appear thromboembolic despite inability to identify an embolic source.89  This patient meets criteria for ESUS as outlined in Table 6. Vasospasm, idiopathic or secondary to autoimmune disease or substances (eg, cocaine, amphetamines, β-blockers, certain chemotherapy and migraine medications),51  can cause transient ischemia and long-term vascular remodeling that increase thrombotic risk. Atherosclerotic changes in imaging or pathology specimens? Tissue Plasminogen Activator (tPA) CBC was repeated and in the absence of hematologic abnormalities, MPN and PNH were considered unlikely. Cite one or two papers to support your answer. Has the heart been examined for a cardioembolic source? She was started on a heparin drip. Continue treatment until pain settles (usually within 1–2 weeks, although the thrombosed vein may be palpable and tender for several weeks to months). In cases when the arteries are not damaged, the thrombosis can reduce or even block the blood supply, causing a stroke, a heart attack or peripheral vascular disease. Imaging was reviewed with radiology and there was no evidence of anatomical abnormalities in the cerebral circulation. 0000034667 00000 n Clot removal through a balloon catheter placed into the affected artery or through open surgery on the artery (embolectomy) Opening of the artery with … The major goal of treatment remains fast and efficient recanalization – surgical, interventional or thrombolytic. Treatment of Thrombosis. In most cases, arterial thrombosis follows rupture of atheroma (a fat-rich deposit in the blood vessel wall), and is therefore referred to as atherothrombosis. Blood thinners. However, the approach to nonatherosclerotic and noncardioembolic arterial thrombosis, referred to here as unexplained arterial thrombosis, is less clear. Arterial thromboembolism associated with COC is uncommon but well described. Although some arterial events are incidentally identified, they still require thorough diagnostic evaluation. Symptoms include pain and swelling in one leg, chest pain, or numbness on one side of the body. Does the patient use amphetamines, cocaine, or anabolic steroids? Were anatomic abnormalities seen in artery leading to the ischemic area (web, fibromuscular dysplasia, dissection, vasculitis, external compression)?
