Abstract
Abstract: Cerebral hypoperfusion can occur during aortic surgery. We present a case in which malposition of the selective antegrade cerebral perfusion (SACP) catheter was identified using carotid ultrasonography. A 66-year-old man underwent total arch replacement. SACP was initiated via the brachiocephalic artery following deep hypothermic circulatory arrest. However, right forehead regional oxygen saturation (rSO2) remained unchanged. Carotid ultrasonography revealed no blood flow in the right common carotid artery, suggesting catheter malposition into the right subclavian artery. After a slight catheter withdrawal, blood flow was restored, and rSO2 increased. Carotid ultrasonography, along with rSO2 monitoring, is recommended for evaluating cerebral perfusion during SACP.
期刊介绍：
Annals of Cardiac Anaesthesia (ACA) is the official journal of the Indian Association of Cardiovascular Thoracic Anaesthesiologists. The journal is indexed with PubMed/MEDLINE, Excerpta Medica/EMBASE, IndMed and MedInd. The journal’s full text is online at www.annals.in. With the aim of faster and better dissemination of knowledge, we will be publishing articles ‘Ahead of Print’ immediately on acceptance. In addition, the journal would allow free access (Open Access) to its contents, which is likely to attract more readers and citations to articles published in ACA. Authors do not have to pay for submission, processing or publication of articles in ACA.
