Control of major haemorrhage associated with pancreatic pseudocysts by transcatheter arterial embolization

Massive haemorrhage from a pancreatic pseudocyst is an uncommon cause of upper gastrointestinal bleeding. The condition carries a high mortality and presents a major clinical problem both in terms of timely diagnosis and appropriate surgical therapy. Four patients are presented with pseudocyst-related bleeding arising from the gastroduodenal artery. In all instances the bleeding was successfully controlled by transcatheter embolization with gelfoam. No untoward sequelae were noted and the occlusion remained effective as shown by follow-up angiography 2 months later. The importance of early diagnostic angiography is stressed and it is concluded that interventional angiography may obviate the need for high risk emergency surgery.
