Abstract

PURPOSE: To determine the therapeutic effect of transcatheter embolization in the treatment of splanchnicpseudoaneurysm.
MATERIALS AND METHODS
This study involved eleven patients who underwent embolization for thetreatment of splanchnic pseudoaneurysm. Nine were men and two were women ; their ages ranged from 8 to 74 (mean,51) years. The etiology of these cases included postoperative pseudoaneurysm(n=4), pancreatitis(n=3), stabinjury(n=1), and suspected infection(n=1), while two cases were uncertain. The locations of the pseudoaneurysmwere the splenic artery(n=4), the gastroduodenal artery(n=3), the hepatic artery(n=2), the celiac artery(n=1), andboth the right renal and lumbar artery(n=1). All patients underwent angiography prior to embolization. Thematerials used during embolization were a microcoil, a 5-cm metallic guide wire, and a detachable balloon.
RESULTS
Embolization was successful in all eleven cases. Among nine cases in which follow-up was possible, angiographywas performed in four, and five cases of thrombus were confirmed by abdominal CT. Three of these nine patientsunderwent re-embolization. One patient underwent elective surgery for a pseudocyst due to pancreatitis.
CONCLUSION
Transcatheter embolization is a safe and convenient modality for the treatment of splanchnic pseudoaneurysm.
