Multimodality treatment of pancreatic pseudoaneurisms.
Vascular lesions of pancreatitis manifest in the form of haemorrhage into the pseudocyst (PC), the development of pseudoaneurisms (PA) or splenic lesions. Between 1987 and 1996 31 patients were found to develop vascular lesions either in the form of haemorrhage into a PC (12) or PA (19). Diagnosis of pancreatic PA was established preoperatively in 8 cases only. Gastrointestinal (GI) bleeding manifested in 12 patients, but only in 6 of them was the pancreatic origin of the bleeding considered. All patients were operated. For the management of the lesions resection of the pancreas (11 cases) or ligation of the bleeding vessel with external or internal drainage of the PC was performed (12 cases). Simple external drainage of a haemorrhaged PC in 3, and cystoduodenostomy or cystogastrostomy was performed in 5 cases respectively. Intraoperatively moderate bleeding gave some concern (7 cases), while post operatively pancreatic fistula developed in 9 patients drained externally. All stopped spontaneously. In two cases severe GI bleeding occurred post operatively. In both cases embolization of the bleeding vessels was performed successfully. No operative mortality occurred. The mean follow-up time was 40.6 months (5-106). Five patients died of unrelated causes, 3 patients underwent subsequent pancreatic operation, and 74.2% of the patients are doing well. Development of pancreatic PA was associated with a longer observation or conservative treatment period. Angiography should be considered whenever severe upper GI bleeding occurs in patients with known pancreatic disease and the source of bleeding is obscure. In selected cases selective embolization of the bleeding site may provide definitive treatment.
