Acute and Resistant İntraoperative Hypertension during Mitral Valve Replacement: A Case Presentation
Main Article Content
Abstract
Background: Intraoperative hypertension continues to be a significant cause of morbidity and mortality for patients undergoing surgery. In this case presentation, an instance of sudden, unexpected, and resistant hypertension during surgery will be discussed in a patient who underwent mitral valve replacement.
Case report: A 75-year-old patient with known coronary artery disease and advanced mitral stenosis underwent mitral valve replacement surgery. During the intraoperative process, after the completion of cannulation procedures and transitioning to partial bypass, a sudden increase in blood pressure was observed in the patient. Blood pressure was only brought under control through the intravenous administration of a triple antihypertensive agent. Upon postoperative evaluation following a smooth completion of the surgery and discharge, findings suggested that the cause of the hypertension in the patient might be renovascular hypertension.
Conclusions: Intraoperative hypertension, when unexpected and sudden, can lead to an increase in mortality and morbidity. During the intraoperative process, efforts should be made to identify the underlying causes promptly, and appropriate interventions should be carried out. In the postoperative period, patients should be thoroughly evaluated for underlying reasons.
