Ward WH, Platz TA, Pond KT, Southern FA, Moore EM: Iatrogenic venous pseudoaneurysm: case report and review of the literature. Vascular. 2009 Nov-Dec;17(6):355-8.
Iatrogenic venous pseudoaneurysm following venipuncture is an extremely rare complication of a very common medical procedure. A review of the vascular surgical literature revealed that only two cases of venous pseudoaneurysm secondary to venipuncture have been reported in the past half-century. We report the case of a 64-year-old anticoagulated male with a 7-month history of right arm swelling after venipuncture. The patient, on warfarin therapy for chronic atrial fibrillation, described progressive swelling at a previous venipuncture site. He eventually underwent limited two-dimensional ultrasonography, performed for a suspected hematoma, revealing a 4.3 x 3.3 x 2.0 cm pseudoaneurysm of the right basilic vein. These findings were later confirmed by a formal venous duplex sonogram. Similar to other forms of aneurysm and focal vascular dilation, the risks of venous psuedoaneurysm include embolism, thrombosis, and the compression of adjacent structures. Although both thrombin injection and coil embolization have been described as nonsurgical treatment options for arterial pseudoaneurysms, surgical resection may be the most appropriate approach for those with a venous equivalent. The segment of basilic vein containing the pseudoaneurysm was resected. This case demonstrates the need for physicians to consider venous pseudoaneurysm as a possible complication of venipuncture in individuals undergoing anticoagulation therapy. |
