Abstract:
We have described our technique of open partial conversion (OPC; n = 5) with aortic banding and endograft preservation for the treatment of type II endoleaks. OPC significantly reduced the aortic clamping time (5.0 vs 32.5 minutes; P = .01) relative to endograft explantation (n = 2). Cross-clamping was avoided entirely in three of the procedures. The patients treated with OPC showed a trend toward a decreased operative time (4.8 vs 5.9 hours) and shorter hospital stay (5.7 vs 7.4 days). Follow-up computed tomography scans were available for three of the five OPC patients, which showed resolution of the type II endoleak. The findings from the present study have further demonstrated the safety of OPC for the treatment of type II endoleaks.
