The case of a @entity1 who presented with a ruptured @entity438 and @entity1264 is presented. Angiography revealed a ruptured @entity438 in the middle of the upper arm. Repair of the artery with autogenous vein grafting was impossible due to the extremely brittle brachial artery and accompanying veins. The blood supply distal to the @entity439 was secured by collaterals, and the @entity439 , including a relatively long portion of the brachial artery and veins adjacent to the @entity439 , was resected. The @entity1 died of massive @entity548 from the subclavian artery of the involved side 9 days postoperatively. Histological and immunohistological examinations of the tissues involved in the @entity1756 were conducted. The resected brachial artery and veins were surrounded by hypertrophied tissue which tested positive for @entity4483 protein and negative for @entity2283 and action. These findings suggest that the origin of the proliferating tissue was not mesodermal @entity1141 , but @entity3292 occurring near or in the vessels. @entity1756 in a @entity1 with @entity4786 should not be treated with reconstruction of the vessels. The treatment of choice is surgical or endovascular occlusion of the vessels involved.
