Abstract Background The complexity of the case, including the rarefied simultaneous occurrence of complications—iatrogenic, as well as reperfusion injury, invite reporting and publication. Case presentation A 39-year-old woman with a single-functioning left kidney, previous left renal artery stenting (RAS), and known hypercoagulopathy was hospitalized for flash pulmonary edema, elevated serum creatinine (9.7 mg/dl), and refractory hypertension. She was subsequently referred to our center [2] for endovascular treatment of acute renal ischemia (AKI) due to RAS occlusion. Periprocedural complications of guide-wire arterial perforation and reperfusion injury resulted in life-threatening hemorrhage. Conclusions Following more than 48 h of hypoperfusion of the left kidney, revascularization of the thrombosed RAS was successfully attempted with selective, trans-catheter thrombolysis, and balloon angioplasty. Ultra-selective, nephron-sparing coil embolization was successfully performed. The patient’s creatinine level decreased to 2.8 mg/dl at 12 days and to 1.5 mg/dl at 3 months. After 1 year of follow-up, the stent remains patent, and the patient is asymptomatic with stable renal function.
