Due to unsuitable femoral and subclavian accesses, the patient underwent a transcaval transcatheter AVR (TAVR) procedure, complicated by the development of an iatrogenic infrarenal aortic pseudoaneurysm with aortocaval fistula. Scoliosis can cause varying anatomic relationships between retroperitoneal vessels and intervertebral disk spaces, which increase the difficulty of the procedure and consequently lead to this vascular complication. Although most aortocaval fistulas close spontaneously after 1 year, the risk of pseudoaneurysm rupture in this critical area was crucial in the decision of a new successful percutaneous aortic stent intervention.engHSM CARAgedHumansMaleAneurysm, False* / diagnostic imagingAneurysm, False* / etiologyAneurysm, False* / surgeryAortic Valve / diagnostic imagingAortic Valve / surgeryAortic Valve Stenosis* / diagnostic imagingAortic Valve Stenosis* / surgeryHeart Valve Prosthesis*Risk FactorsScoliosis* / surgeryTranscatheter Aortic Valve Replacement* / adverse effectsTranscatheter Aortic Valve Replacement* / methodsTreatment Outcomejournal article10.1002/ccd.30140
