ABSTRACT
Aneurysms of the superior mesenteric artery branches are rare. Spontaneous intra-abdominal hemorrhage resulting from rupture of a visceral artery aneurysm is difficult to diagnose and carries high mortality. We present a case in which a rupture of the right colic artery aneurysm presented as an acute abdomen. Diagnosis was established intraoperatively. Angiography and a high degree of suspicion are valuable diagnostic tools. Exact etiology was not determined in our case. Because of high risk of rupture, aneurysms of the superior mesenteric artery branches should be resected.

The peak left ventricular stroke work index developed in response to rapid volume infusion was calculated in 34 patients undergoing either aorto-iliac or peripheral vascular surgery. The average preoperative maximum stroke work index in patients recovering without cardiac complication was 0.47 (+/- 0.2) J/m2 compared with a mean value of 0.28 (+/- 0.14) J/m2 in patients with perioperative cardiac complications. This difference was significant (P less than 0.01). Clinical cardiac risk analysis identified a group of high risk patients in which more than half developed cardiac complications and a low risk group in which no cardiac complications were observed. There was a significant difference in maximum stroke work indices in these two groups.

A case of penetrating metal fragment injury to the cubital fossa with subsequent development of a false aneurysm of the brachial artery with a fistulae to the vena comitans and median basilic vein is described. Surgical management involved aneurysmectomy, interposition cephalic vein graft and lateral repair of the vena comitans. Early angiography should be considered in penetrating injuries near major limb vessels, as the initial signs and symptoms of vascular injury may be minimal.
