ABSTRACT
OBJECTIVE:
To determine the role of the arterial splenomesenteric anastomosis (ASMA) vascular reconstruction technique in terms of arterial vascular complications in pancreas transplant (PT) recipients. SUMMARY BACKGROUND DATA The ASMA technique was first described in 1992 by Hospital Clínic Barcelona group. Regardless that the iliac Y-graft technique is the most frequently used worldwide, evidence of arterial complications and implications of using a different back-table reconstruction is conspicuously absent in the literature.METHODS:
Descriptive review of 407 PTs performed at a single center (1999-2019) by analyzing the type of arterial reconstruction technique, focusing on ASMA. The endpoints were the management of arterial complications and long-term patient and graft survival.RESULTS:
ASMA was performed in 376 cases (92.4%) and a Y-graft in 31 cases (7.6%). A total of 34 arterial complications (8.3%) were diagnosed. In the ASMA group (n=30, 7.9%) they comprised 15 acute thrombosis; 4 stenosis; 1 pseudoaneurysm and 10 diverse chronic arterial complications while in the Y-graft group (n=4, 12.9%) 3 acute thrombosis and 1 chronic artery-duodenal fistula occurred. Graft salvage was achieved in 16 patients (53.3%) from the ASMA group and in 2 (50%) from the Y-graft. After a median follow-up of 129.2 (IQR 25-75%, 77.2 -182) months the overall graft and patient survival for the whole cohort at 1, 5, and 10 years was 86.7%, 79.5%, 70.5%, and 98.5%, 95.3%, 92.5%, respectively.CONCLUSIONS:
The ASMA proves to be a safe and more easily reproducible technique and should therefore be considered for first-line back-table reconstruction in the PT population.
