Sir,

Ischemic stroke is occasionally complicated with acute aortic dissection. However, hemorrhagic stroke with acute aortic dissection was extremely rare.[1],[2],[3] We herein report a fatal case of the concurrence of intracranial hemorrhaging and Stanford type A acute aortic dissection with cardiac tamponade, confirmed by computed tomography (CT).

A 79-year-old woman fell down at work. Her personal and family history was unremarkable. Initially, she was able to speak with those around her. However, when emergency medical technicians (EMTs) checked her, she slipped into a deep coma approximately 30 min after her collapse. Her initial vital signs were as follows: Glasgow coma scale, E1V1M1; blood pressure, 214/100 mmHg; heart rate, 52 beats/min; respiratory rate, 10 breaths/min; SpO2, 99% under room air; temperature, 36.4°C. As she was snoring, the EMTs manually secured her airway and assisted in respiration using a bag valve mask. After 6 min, she entered cardiac arrest with 110 heart beats/min, so the EMTs began chest compression. Two minutes later, the staff of a physician-staffed helicopter met her and performed tracheal intubation and mechanical ventilation, secured a venous route, and delivered infusion of adrenaline every 4 min. The patient was transported via helicopter and underwent electrical shock because she developed ventricular fibrillation in the air. When she arrived at our hospital, she remained in cardiac arrest. Her initial rhythm was asystole. Ultrasound showed echo-free space around her heart, so she underwent emergency thoracotomy and pericardiotomy, resulting in the removal of a 300-g clot. However, she did not obtain spontaneous circulation. Autopsy imaging disclosed intraventricular and subarachnoid hemorrhaging in her head as well as Stanford A type aortic dissection [Figure 1]. Permission to perform a standard autopsy was not obtained from her family.{Figure 1}

This is an extremely rare case of the concurrence of intracranial hemorrhaging and Stanford type A acute aortic dissection with cardiac tamponade. The bleeding source of intracranial hemorrhaging might have been a ruptured cerebral aneurysm or dissection of a cerebral artery in the posterior circulation, as head CT showed predominant hemorrhaging in the fourth ventricle. The mechanism underlying the concurrence might involve antecedent intracranial hemorrhaging inducing hypertension, which was confirmed in the present case, resulting in the occurrence of acute aortic dissection in a short time. Because the rupture of the aorta invariably causes a marked fall in blood pressure, the occurrence of cerebral hemorrhaging following aortic dissection with hemopericardium is highly unlikely.[3],[4] Thus, we presume that the aortic rupture occurred after the intracranial hemorrhaging. In addition, genetic factors contributing to a degenerative vasculature may have caused the concurrence.[2] As vascular diseases are systemic diseases, physicians should be alert for their concurrence when treating a patient with a vascular accident.
