Midterm results of internal iliac artery aneurysm embolization.

OBJECTIVE: We describe the immediate and midterm results of endovascular treatment of isolated internal iliac artery aneurysms (IIAA). METHODS: This was a retrospective single center study. From 2005 to 2014, data from 20 consecutive patients who had an embolisation for an isolated atherosclerotic internal iliac artery aneurysm underwent an endovascular treatment. We retrospectively evaluated the technical aspects and outcomes. RESULTS: The mean aneurysm diameter was 42mm (range 30-97mm). No perioperative deaths or treatment failures occurred. No endoleaks or secondary aneurysm ruptures were observed during the follow-up. Three patients experienced disabling buttock claudication, which was spontaneously remissive in two cases. No relationship was found between buttock claudication and the patency of the contralateral internal iliac artery and the deep femoral artery. Six patients (30%) died during follow-up. Among these, three patients died due to cardiovascular events. The mean follow-up interval was 24 months (range 6-96 months). CONCLUSION: The endovascular treatment of isolated internal iliac artery aneurysm is safe in the short-term and could prevent secondary aneurysm rupture at midterm.

Management of pancreatic trauma.

INTRODUCTION: Pancreatic trauma (PT) is associated with high morbidity and mortality; the therapeutic options remain debated. MATERIAL AND METHODS: Retrospective study of PT treated in the University Hospital of Grenoble over a 22-year span. The decision for initial laparotomy depended on hemodynamic status as well as on associated lesions. Main pancreatic duct lesions were always searched for. PT lesions were graded according to the AAST classification. RESULTS: Of a total of 46 PT, 34 were grades II or I. Hemodynamic instability led to immediate laparotomy in 18 patients, for whom treatment was always drainage of the pancreatic bed; morbidity was 30%. Eight patients had grade III injuries, six of whom underwent immediate operation: three underwent splenopancreatectomy without any major complications while the other three who had simple drainage required re-operation for peritonitis, with one death related to pancreatic complications. Four patients had grades IV or V PT: two pancreatoduodenectomies were performed, with no major complication, while one patient underwent duodenal reconstruction with pancreatic drainage, complicated by pancreatic and duodenal fistula requiring a hospital stay of two months. The post-trauma course was complicated for all patients with main pancreatic duct involvement. Our outcomes were similar to those found in the literature. CONCLUSION: In patients with distal PT and main pancreatic duct involvement, simple drainage is associated with high morbidity and mortality. For proximal PT, the therapeutic options of drainage versus pancreatoduodenectomy must be weighed; pancreatoduodenectomy may be unavoidable when the duodenum is injured as well. Two-stage (resection first, reconstruction later) could be an effective alternative in the emergency setting when there are other associated traumatic lesions.
