Left Renal Vein Division in Abdominal Aortic Aneurysm Operations

Aortic clamping during elective operations for infrarenal disease: The influence of clamping time on renal function

“…Another difference from other studies is that the renal vein was ligated in only 7% of our patients as compared with other studies that report a 3% to 10% incidence rate for aortic operations for AAA where most patients had clamping below the renal arteries. 13,14 Our results, which include data from the one patient who died of visceral ischemia with renal insuffiency, are equal to previous data reported from comparable patient groups. Of 41 patients with AAA, with 30 supraceliac and 11 suprarenal aortic clamps, Green et al 6 reported three patients who needed dialysis.…”

Long-term safety of left renal vein division and ligation to expedite complex abdominal aortic surgery

“…Proponents of LRVDAL have described it as a safe adjunct to aortic surgery 6 without significant in-hospital deterioration in renal function. 7,8,9 However, other authors have opposed LRVDAL and reported renal derangements such as an increase in BUN/Cr, decrease in eGFR, venous congestion causing kidney swelling, and sometimes capsular rupture. [10][11][12][13][14] In order to determine whether the vein could be divided and safely ligated, Calligaro et al 15 described "test clamping" the renal vein to check stump pressures.…”

Clinical Efficacy and Cost per Quality-Adjusted Life Years of Pararenal Endovascular Aortic Aneurysm Repair Compared With Open Surgical Repair

“…Unlike previous authors, we found no deterioration in renal function without reconstitution of renal vein integrity. 22 On the contrary, reducing paraaortic dissection and mobilization helped us prevent visceral atheroembolization, and as others have reported, 28,29 we also have found left renal vein re-anastomosis unnecessary due to adequate collateral circulation.…”
