Vascular occlusions due to cerebral trauma have always been regarded as great rarities. However, we have found hypo-dense foci of vascular distribution in 3.5% of 3500 CT examinations for trauma during the late phase. Lesions in the vascular territory of the posterior cerebral artery are usually the result of supratentorial pressure rise from epidural and subdural haematomas, leading to compression of the vessels against the edge of the tentorium. Typical infarcts in the territory of the medial and anterior cerebral arteries were found only rarely by CT after cerebral trauma. Infarcts at the watersheds between the three vascular territories were found with surprising frequency and small infarcts were found in the basal ganglia. It is assumed that these were due to ischaemic or hypoxic events due to cardiac or pulmonary complications during the initial phase.
因脑外伤导致的血管闭塞一直被视为极为罕见的情况。然而，在3500例晚期创伤CT检查中，我们发现3.5%的病例存在血管分布区的低密度灶。大脑后动脉血管区域的病变通常是由于硬膜外和硬膜下血肿导致幕上压力升高，致使血管被压向小脑幕边缘所致。脑外伤后，通过CT很少能发现大脑中动脉和大脑前动脉区域的典型梗死灶。在三个血管区域之间的分水岭处发现梗死灶的频率惊人，并且在基底节区发现了小梗死灶。据推测，这些是由于初始阶段心脏或肺部并发症导致的缺血或缺氧事件所致。
