A super-selective coil impregnation therapy for pancreatic duct haemorrhage caused by pseudoaneurysm rupture

Abstract

BACKGROUND: Haemorrhage of pancreas is a rare cause of upper gastrointestinal bleeding, and currently there is no clinical satisfactory treatment for this disorder. OBIECTIVE: The present study envisaged to treat the haemorrhage of pancreas caused by pseudoaneurysm rupture using interventional super-selective coil impregnation therapy, so as to achieve a better treatment efficacy. METHODS: Six cases presenting haemorrhage of pancreas were employed for the study, including 5 cases caused by splenic artery pseudoaneurysm and 1 case caused by superior pancreatic artery pseudoaneurysm. In all 6 patients the femoral artery was punctured using Seldinger femoral artery puncture and intubation technique. Subsequently, a catheter was inserted into the abdominal trunk and the contrast medium was injected, and the pseudoaneurysm was developed. A coil was then inserted into the distal end and proximal end of the pseudoaneurysm, respectively, leading to the elimination of the pseudoaneurysm. RESULTS: All 6 patients with pancreatic haemorrhage were implanted with coil at the distal and proximal end of the aneurysm, until the aneurysm disappeared during intraoperative angiography. Further, clinical symptoms such as abdominal pain, melena and hematemesis disappeared after the operation. No recurrence of the symptoms was observed in the studied population. CONCLUSION: A 100% treatment outcome can be achieved in patients with pseudoaneurysm-induced haemorrhage of pancreas using interventional super-selective coil embolization.
