Abstract
We retrospectively reviewed clinical characteristics and treatment outcome on 11 pancreaticoduodenal artery aneurysm (PDAA) cases from 1990 to 2013, including nine cases of ruptured PDA and two cases of non-ruptured PDAA. Regarding ruptured sites, there were seven cases of retroperitoneal ruptures and one case each of intraduodenal rupture and intraperitoneal rupture. The leading symptom was abdominal pain. However, in the case of retroperitoneal rupture, the symptoms were resolved in some cases. This finding clearly demonstrates that close attention needs to be paid to clinical characteristics. Narrowing or obstruction of the celiac artery was observed in seven cases and patency was observed in four cases. Treatment was performed with transcatheter arterial embolization (TAE) for eight cases, TAE + ligation for two cases and lump excision for one case. TAE was combined with abdominal section, or vice versa, depending on the condition of the patient. TAE-related complications were observed in three cases and a surgical complication in two cases. Additional operations, such as bypass, arcuate ligament incision or stenting, were not performed in any case because complications due to ischemia were not recognized. Symptoms or findings of recurrence were also not recognized during the observation period. TAE is the first-line choice of treatment, which could be combined with open surgery. According to our research review findings, recurrence after treatment is unlikely. Therefore, we consider it unnecessary to perform additional operations.
