Key result
The VORTEC technique reduced left renal artery anastomosis time (4.6 vs 19.8 min, p<0.001) and 1-year renal dysfunction aggravation (4 vs 8 patients, p=0.025) versus conventional methods.
Why the study?
Hybrid debranching combined with conventional open surgery and endovascular repair effectively treats TAAA, but techniques to reduce renal artery anastomosis time are needed.
Does the VORTEC technique reduce the time of renal artery anastomosis and complications compared to conventional anastomosis in patients with thoracoabdominal aortic aneurysms?
Cohort (n=57)

Does the VORTEC technique reduce the time of renal artery anastomosis and complications compared to conventional anastomosis in patients with thoracoabdominal aortic aneurysms?
Absolute Event Rate: 4.6% vs 19.8%
p-value: p=<0.001
The VORTEC technique significantly reduces renal artery anastomosis time and the incidence of renal dysfunction aggravation compared to conventional anastomosis during hybrid repair of thoracoabdominal aortic aneurysms.
May shorten renal anastomosis time in hybrid TAAA repair; leaves open outcome benefits versus standard techniques.
OBJECTIVE: Hybrid debranching technique combined with conventional open surgery and endovascular repair was an effective treatment for thoracoabdominal aortic aneurysm (TAAA). We propose a new technique to reduce the time of RA anastomosis. MATERIALS AND METHODS: The hybrid staged operation procedure was evaluated in the period of 2013 and 2017 in three academic centers. The bilateral renal artery anastomosis in the experimental group used VORTEC technique. In the control group, the bilateral renal artery reconstruction was performed by conventional artificial blood vessel anastomosis. Primary outcome was technical success, the time of renal artery anastomosis, and major complications. Long term follow-up up to 7 years was evaluated as well. RESULTS: In total 57 patients were enrolled. Compared with the control group, there was a statistical difference in the mean time of left RA anastomosing (19.8 vs 4.6 min, p <0.001) and the right RA anastomosing (20.5 vs 4.6 min, p <0.001) in the experimental group. While the aggravation of renal dysfunction occurred in 12 patients in 1 year after the stage surgery, and there was a statistical difference between the experimental group and the control group (4 vs 8, p=0.025). CONCLUSION: The VORTEC technique could help reducing the time of RA anastomosing and get lower complication rate and better effect during long-term follow up.

Zhang et al. (2021) conducted a cohort in thoracoabdominal aortic aneurysm (n=57). VORTEC technique vs. conventional artificial blood vessel anastomosis was evaluated on mean time of left renal artery anastomosis (p=<0.001). The VORTEC technique reduced left renal artery anastomosis time (4.6 vs 19.8 min, p<0.001) and 1-year renal dysfunction aggravation (4 vs 8 patients, p=0.025) versus conventional methods.
