Mechanical Thrombectomy for Acute Ischemic Stroke Arising from Thrombus of the Left Superior Pulmonary Vein Stump after Left Pneumonectomy: A Case Report
Abstract
Pulmonary vein thrombosis is a rare disease but can cause severe complications. However, pathophysiology of this entity is not fully understood. We report a case of mechanical thrombectomy for acute ischemic stroke arising from thrombus of the left superior pulmonary vein stump after left pneumonectomy. A 67-year-old male without atrial fibrillation presented with middle cerebral artery occlusion 11 days after left pneumonectomy. Contrast-enhanced computed tomography showed thrombus in the left superior pulmonary vein stump. He received mechanical thrombectomy and had a good postoperative course. The retrieved embolus was macroscopically red thrombus and histological examination revealed that the embolus consisted of fibrin and erythrocyte-rich thrombus. Thrombus formation in a pulmonary vein stump after lung resection may be an embolic source of AIS. Mechanical thrombectomy and anticoagulation is effective for the treatment of this pathology.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
