Patients are usually unstable and are treated with surgical exploration. We present a case of axillary venous injury that was treated in the operating room with intravenous placement of a self-expanding Viabahn endoprosthesis (W.L. Gore). The device was delivered to the injured site percutaneously via a basilica vein, with immediate control of hemorrhage. ( J Vasc Surg 2004;40:1243-4.)

Publications often contain evidence that confirm or disprove annotations, such as putative protein functions, however, it is increasingly difficult for biologists to identify and process published evidence due to the volume of papers and the lack of a systematic approach to associate published evidence with experimental data and annotations. Natural Language Processing (NLP) tools can help address the growing divide by providing automatic high-throughput detection of simple terms in publication text. However, NLP tools are not mature enough to identify complex terms, relationships, or events.

A 58-year-old hypertensive man was transferred from an outside hospital with the history of sudden onset of pain, paresis, and purple discoloration of both lower extremities extending up to the umbilicus. Femoral and distal pulses were absent on examination. Contrast-enhanced computed tomography showed a 3.8-cm infrarenal AAA with a large thrombus occluding the bifurcation of the iliac arteries. The patient was treated emergently with an AneuRx stent-graft that excluded the thrombus and the AAA from the circulation, with return of distal pulsation and recovery of ischemic and neurological deficits. At 10-month follow-up, the patient remained asymptomatic. Selected cases of acute thrombosis of AAA with favorable anatomy can be treated utilizing endovascular grafts. Extra precaution should be taken to prevent embolization during catheter manipulation and introduction of the large stent-graft devices.
