“…Local excision of the artery with end‐to‐end anastomosis has also been successful. This anastomosis can be difficult because the artery may be too short, tending to cause tension on the suture line [40]. A saphenous vein or hypogastric artery interposition grafts have been reported to give acceptable long‐term results, and the splenic artery can be used when there is extensive peri‐aortic fibrosis.…”

“…The human coronary collateral circulation is far more extensive than in most species. 5,6 Although a preformed collateral circulation exists in the kidney, [7][8][9][10][11] its abundance relative to other species is unknown. Computational modeling has shown that collateral arteries contribute to reductions in resistance and increases in flow distal to an arterial occlusion more than the distal microcirculation, and are considered to be protective in occlusive arterial disease in the heart, brain, and peripheral circulations.…”

The collateral circulation can adapt to bypass major arteries with limited flow and serves a crucial protective role in coronary, cerebral, and peripheral arterial disease. Emerging evidence indicates that the renal collateral circulation can similarly adapt and thereby limit kidney ischemia in atherosclerotic renovascular disease. These adaptations predominantly include recruitment of preexisting microvessels for arteriogenesis, with de novo vessel formation playing a limited role. Yet, adaptations of the renal collateral circulation in renovascular disease are often insufficient to fully compensate for the limited flow within an obstructed renal artery and may be hampered by the severity of obstruction or patient comorbidities. Experimental strategies have attempted to circumvent limitations of collateral formation and improve the prognosis of patients with various ischemic vascular territories. These have included pharmacological approaches such as endothelial growth factors, renin-angiotensin-aldosterone system blockade, and If-channel-blockers, as well as interventions like preconditioning, exercise, enhanced external counter-pulsation, and low-energy shock-wave therapy. However, few of these strategies have been implemented in atherosclerotic renovascular disease. This review summarizes current understanding regarding the development of renal collateral circulation in atherosclerotic renovascular disease. Studies are needed to apply lessons learned in other vascular beds in the setting of atherosclerotic renovascular disease to develop new treatment regimens for this patient group.

Bilateral traumatic renal artery occlusion with survival after late reconstitution of arterial flow

Abstract: Survival after bilateral traumatic renal artery occlusion is uncommon. A patient is described who recovered useful renal function despite a 12‐hour delay in reconstitution of arterial flow. Postoperative oliguria latest 45 days, necessitating prolonged haemodialysis.
