Diagnostic Ultrasound: On-Site Diagnosis of Type B Aortic Dissection During Cataract Surgery.

We report a case of aortic dissection occurring during cataract surgery under local anesthesia, which was diagnosed on-site by point-of-care ultrasound. Intimal flaps were detected in the abdominal aorta, whereas the parasternal view showed no abnormalities in the aortic root or left ventricular function. According to these ultrasound findings, a Stanford type B aortic dissection was more likely than a type A aortic dissection, and imminent death was unlikely. Therefore, we decided to resume and complete the surgery. Subsequent computed tomography (CT) confirmed the point-of-care diagnosis. The patient was transferred to a tertiary hospital for medical treatment.
