Although each year approximately 30,000 to 50,000 cases of subarachnoid hemorrhage in the United States are caused by the rupture of intracranial saccular aneurysms, there is little information in the literature documenting the association of aneurysmal rupture with closed head injury.
A 61-year-old woman presented after a motor vehicle accident with multiple injuries, including a severe closed head injury. Computed tomography revealed a diffuse basal subarachnoid hemorrhage. Angiography revealed the source as a large aneurysm arising from the ophthalmic segment of the left carotid artery.
After the patient was stabilized for her multiple injuries, she underwent craniotomy and clipping of the aneurysm. She recovered without developing new neurological deficits.
Although the association of head trauma and aneurysmal subarachnoid hemorrhage is rare, the presence of significant basal subarachnoid blood on a computed tomographic scan should alert the physician to the possibility of a ruptured aneurysm.
尽管在美国每年约有30,000至50,000例蛛网膜下腔出血是由颅内囊状动脉瘤破裂所致，但文献中几乎没有资料记载动脉瘤破裂与闭合性颅脑损伤之间的关联。
一名61岁女性在机动车事故后出现多处损伤，包括严重的闭合性颅脑损伤。计算机断层扫描显示弥漫性基底池蛛网膜下腔出血。血管造影显示出血源为一个源自左颈动脉眼段的大动脉瘤。
患者因多处损伤病情稳定后，接受了开颅手术并夹闭动脉瘤。她康复后未出现新的神经功能缺损。
尽管头部创伤与动脉瘤性蛛网膜下腔出血之间的关联罕见，但计算机断层扫描显示有大量基底池蛛网膜下腔出血时，医生应警惕动脉瘤破裂的可能性。
