Short-term outcomes following elective transcatheter arterial embolization for splenic artery aneurysms: data from a nationwide administrative database
نویسندگان
چکیده
BACKGROUND Splenic artery aneurysm (SAA) rupture is life-threatening. Although elective transcatheter arterial embolization (TAE) suggested low in-hospital death in previous studies, there has been no large multi-center study of elective TAE for SAA. PURPOSE To examine the short-term outcomes of TAE for splenic artery aneurysm (SAA) and analyze the factors associated with the outcomes, including liver cirrhosis, using a nationwide administrative inpatient database. MATERIAL AND METHODS We identified patients who received elective TAE with a principal diagnosis of SAA. We assessed the patient background characteristics, comprising age, sex, and specific co-morbidities, including liver cirrhosis. The outcomes included the rate of TAE-related complications (acute pancreatitis, splenic infarction, splenic abscess, or intraperitoneal hematoma), length of stay, and in-hospital mortality. RESULTS Among 18.3 million inpatients in the database between July 2010 and March 2013, we identified 534 patients who received elective TAE for SAA at 229 participating hospitals. Fifty-four (10.1%) patients had liver cirrhosis. No in-hospital deaths were observed. Thirty-two (6.0%) patients had at least one TAE-related complication. A multivariate linear regression analysis revealed that liver cirrhosis was significantly associated with longer length of stay (9.5 days; 95% confidence interval [CI], 7.0-12.0 days; P < 0.001). A logistic regression analysis showed that liver cirrhosis was not significantly associated with TAE-related complications (odds ratio, 0.99; 95% CI, 0.29-3.39; P = 0.980). CONCLUSION The results revealed no in-hospital mortality and a low complication rate associated with elective TAE for SAA including liver cirrhosis patients.

Middle colic artery aneurysms are rare and most have been reported with rupture or symptom. We report the successful elective treatment of a middle colic artery aneurysm without symptom, which is very rare. It failed to perform transcatheter arterial embolization for anatomical reasons, and, thus, the patient, a 77-year-old man, underwent surgical resection in spite of a history of laparotomy. ...
