Deep Vein Thrombosis in the Upper Extremities Associated with Protein C Deficiency: A Case Report

摘要

Deep vein thrombosis (DVT) is a common disorder but rarely involves the upper extremities. Predisposing causes include neoplasm, central venous catheter or pacemaker lead placement, hematological disease, and aneurysm.1-5 A recent study showed that the prevalence of patients with DVT in the upper extremities (UEDVT) was 3.0%1 and another study suggested 4-10%.6 Of these patients, approximately 50% and 40%, respectively, were reported to have had prior central catheter placements and cancer.1 Hematological disease is extremely rare as the cause of UEDVT. We report a 50-year-old man with UEDVT as the primary presentation of protein C deficiency.
