Injury of a medial sacral vessel during lumbar laminectomy.

Vascular injury sustained during neurosurgical procedures is surprisingly rare, especially considering the anatomic proximity of major blood vessels to the vertebral column. Mortality rates are high if the injury is not recognized and definitive management is delayed. Case reports include massive hemorrhage, arteriovenous fistulas, and development of false aneurysms. Diagnostic CT scan and arteriography are useful if the patient's condition permits; however, rapid intervention is crucial to the patient's survival. After reviewing the current surgical literature, we present a case of medial sacral artery injury occurring during laminectomy.

External iliac artery occlusion due to pelvic fracture: management with a cross-femoral bypass graft.

Vascular injury is not uncommon in cases of major pelvic trauma. Venous injury is by far the most common associated problem and may lead to exsanguinating hemorrhage. Arterial injury is less common, but certainly not without associated morbidity and mortality. It can lead to persistent bleeding after fixation and stabilization of the pelvic girdle, and occlusion of major pelvic arteries can cause limb ischemia and limb loss. The potential problems with revascularizing the ischemic extremity are (1) other life-threatening injuries that may be present and (2) a retroperitoneal hematoma that can interfere with an anatomic approach. Our solution to the latter problem, as presented here, is placement of a cross-femoral bypass graft, which rapidly and safely restores blood flow in the presence of pelvic fracture and an occluded external iliac artery. The pelvic hematoma is avoided, thereby restoring circulation more quickly, with less blood loss and greater ease.

Acquired immunodeficiency syndrome and mycotic abdominal aortic aneurysms: a new challenge? Report of a case.

The case of a 64-year-old white man with acquired immunodeficiency syndrome and ruptured abdominal aortic aneurysm infected with Salmonella is presented. Five points related to this case are addressed. It is feared that the vascular surgeon may face patients with acquired immunodeficiency syndrome and abdominal aortic aneurysms infected with Salmonella with increasing frequency in the future. This case raises medical, ethical, and moral questions.
