A Case of Brachial Artery Dissection Caused by a Dog Bite

Abstract

We report a case of acute arterial occlusion due to dissection of the brachial artery, which is rare in canine bites, including some bibliographical considerations. The case was an 86-year-old woman. The left upper limb was bitten by apet dog and injured. The chief complaint was swelling of the upper left limb and numbness. Radial artery pulsation could not be detected, and vascular damage was suspected. No obvious wounds were found on the skin. Contrast-enhanced CT showed localized occlusion of the brachial artery. The site of color change in the brachial artery was resected and autologous vein graft replacement was performed. Arterial dissection was found in the resected specimen. Anticoagulant therapy was used for 1 year after the operation, and antiplatelet preparations were taken thereafter for 8 years after the operation.
