All hemodynamically stable patients with chronic pancreatitis and bleeding pseudoaneurysms should undergo prompt initial angiographic evaluation and embolization if possible. Repeated angioembolization is feasible in patients with recurrent bleeding, whether initially embolized or operated. Patients with unsuccessful embolization should undergo emergency hemostatic surgery with ligation of the bleeding vessel in the head of the pancreas and distal resection in patients bleeding from the splenic artery or its branch. The combination of angioembolization and later endoscopic drainage of the pseudocyst via endoscopic retrograde cholangiopancreatography (ERCP) is effective in the majority of the cases of pseudoaneurysms in chronic pancreatitis.

The purpose of this study was to report our experience in treating type II endoleaks after endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms. Two hundred eighteen patients underwent EVAR with a Zenith stent-graft from January 2000 to December 2005. During a follow-up period of 4.5 + or - 2.3 years, solely type II endoleak was detected in 47 patients (22%), and 14 of them underwent secondary interventions to correct this condition. Ten patients had transarterial embolization, and four patients had translumbar/transabdominal embolization. The embolization materials used were coils, thrombin, gelatin, Onyx (ethylene-vinyl alcohol copolymer), and glue. Disappearance of the endoleak without enlargement of the aneurysm sac after the first secondary intervention was achieved in only five of these patients (5/13). One patient without surveillance imaging was excluded from analyses of clinical success. After additional interventions in four patients and the spontaneous disappearance of type II endoleak in two patients, overall clinical success was achieved in eight patients (8/12). One patient did not have surveillance imaging after the second secondary intervention. Clinical success after the first secondary intervention was achieved in two patients (2/9) in the transarterial embolization group and three patients (3/4) in the translumbar embolization group. The results of secondary interventions for type II endoleak are unsatisfactory. Although the small number of patients included in this study prevents reliable comparisons between groups, the results seem to favor direct translumbar embolization in comparison to transarterial embolization.

Treatment of SFA occlusions (TASC IIB and C or Imelda Ia and II) should be done by PTFE bypass rather than by PTFE thrupass, as thrupass is connected with worse early outcome. These results represent only a small category of femoral disease.

These preliminary results suggest that endovascular repair of symptomatic, unruptured AAA is feasible and can be associated with a favourable outcome despite a very high operative risk.
