[Successful open vascular-surgical supracoeliac anastomosis of a bifurcational prosthesis with simultaneous prosthetomesenteric and renal revascularisation in Leriche's syndrome with high occlusion].
BACKGROUND
Based on an extraordinary case -report on a patient with almost symptomless supramesenteric occlusion of the aorta, the successful management and favourable outcome including almost normalised renal function (in addition to appropriate diagnostic and operative tactics) achieved by a technically challenging vascular-surgical intervention and subsequent intensive medical and nephrological care are described.


RESULTS
In a 49-year-old male patient, a "high" aortic occlusion just below the branching of the coeliac trunk with arterial perfusion of the abdomen and the lower extremities via arterial collaterals from the 4 (th) to 6 (th) intercostal arteries was diagnosed. Both renal arteries were occluded leading to a consecutive renal insufficiency with need for dialysis and renovascularly induced hypertension. However, a residual perfusion of the parenchyma of the left kidney was detectable. Therapeutic measures comprised, after haemodialysis with accompanying antihypertensive medication, open supracoeliac aortobifemoral implantation of a prosthesis, revascularisation of the left renal artery (prosthetic bypass) and prostheticomesenteric bypass implantation. Postoperatively, a reestablished renal perfusion was observed in spite of the preoperatively prolonged lack of appropriate arterial perfusion (last dialysis, 11 (th) POD / discharge, 18 (th) POD). At 3 months postoperatively, the patient reported an increase of his body weight of 8 kg (at 6 months, 20 kg; improved but still elevated laboratory parameters indicating renal insufficiency; RR within normal range). Postinterventional MR angiography revealed a regular perfusion of the bifurcational prosthesis and of the bypasses to the superior mesenteric and left renal arteries.


CONCLUSIONS
This exemplary case demonstrates impressively the individual therapeutic chances, options and the potential in the diagnostic and therapeutic interdisciplinary management and its combined expertise. The clinical course in this case indicates that the assessment of the arterial blood supply has to be included in the diagnostic of an acute renal insufficiency associated with anuria. If there is a minimal residual perfusion, which might just be sufficient for maintenance of structural integrity, there is a real chance for a restitution of renal function after successful revascularisation.
