Successful surgical correction of ascending aortic dissection in a kidney transplant patient

Cardiovascular disease is the leading cause of death in patients with a transplanted kidney and in graft loss. We present the first clinical case of successful surgical correction of ascending aortic dissection (DeBakey type I) in a young patient with a functioning kidney graft. The patient underwent the first cadaveric kidney transplantation (KTx), which was complicated by acute humoral rejection and suboptimal graft function. High blood pressure, anemia, elevated blood levels of triglycerides, phosphorus, parathyroid hormone, and uric acid were recorded. A repeat KTx was performed five years later; the patient’s condition and kidney function were satisfactory. Three years later,the patient started experiencing severe pain along the thoracic and lumbar spine; his blood creatinine level was 408 μmol/L. Computed tomography and echocardiography diagnosed DeBakey type I aortic dissection (AD) with critical narrowing of the true aortic lumen at certain levels, dissection of aortic branches. Aortic resection surgery with prosthetic replacement of the ascending aorta according to David procedure with reimplantation of coronary artery orifices according to Kouchoukos technique, prosthetic replacement of the aortic arch with debranching of brachiocephalic artery and left common carotid artery were successfully performed as planned under endotracheal anesthesia, cardiopulmonary bypass and selective pharmacological cold cardioplegia. The peculiarities of the course, possible causes and outcomes of surgical correction of thoracic AD in the patient are discussed.
