Dr. Jerome Cau and Dr. JB Ricco developped a new technique for renal artery bypass in case of restenosis after a percutaneous renal artery stenting (PTRA). The idea is to repair the dameged part of the artery, through a bypass, done in a minimal-invasive way.

The main reason for this being that restenosis after PTRS procedure is reported in a substantial number of patients ranging from 17% to 44%.

Conclusions are highly interesting:
Total laparoscopic renal artery bypass is feasible and safe in patients after failed PTRA. This approach may reduce the morbidity of open repair but is technically demanding and necessitates a large previous experience in total laparoscopic aortic surgery.
