Abstract

Abstract:

Objective To investigate the clinical characteristics, diagnosis, and management of aortic dissection (AD) in patients undergoing hemodialysis through a case report and literature review. Methods We retrospectively analyzed one case of Stanford type B AD in a patient undergoing maintenance hemodialysis (MHD) and reviewed the relevant literature. Results The patient was a young man who had been receiving MHD for more than 5 years and was admitted because of chest pain during dialysis for 1 h. He had longstanding severe secondary hyperparathyroidism and disorders of calcium-phosphorus metabolism. After 1 h of hemodialysis, the patient developed sudden severe chest pain. At the time of symptom onset, blood pressure was measured at 196/103 mmHg. After hemodialysis was terminated, whole-aorta computed tomography angiography showed Stanford type B (Debakey type III) AD. The patient subsequently underwent endovascular aortic repair in the cardiovascular department, recovered smoothly after surgery, and had a favorable prognosis while continuing MHD. Conclusion Appropriate control of intradialytic hypertension and active management of parathyroid hormone levels and hyperphosphatemia are key to preventing AD in patients undergoing hemodialysis.

Key words: renal dialysis, aortic dissection, intradialytic hypertension
