Article Title: | Moderately elevated intracranial pressure produces greater cross-filling of the anterior communicating artery |
Abstract: | This study aimed to investigate whether moderately elevated intracranial pressure is associated with greater cross-filling of the anterior communicating artery on diagnostic cerebral angiography. A retrospective study of 12 patients with subarachnoid hemorrhage was performed. Data on sequential cerebral angiograms and clinical data were used to indirectly estimate intracranial pressure (ICP). Cross-filling of the anterior communicating artery (ACom) was recorded according to our scoring system. Our study included 12 patients with mean age 43 ±11 yrs. Six patients demonstrated greater ICP associated with greater cross-filling of the ACom on initial angiogram. One patient had greater ICP with greater cross-filling on follow-up angiogram secondary to infarction and midline shift. Two patients had lower ICP yet greater cross-filling on follow-up angiogram due to higher injection rate and volume. One patient with no change in ICP demonstrated the same degree of cross-filling. A markedly elevated ICP is traditionally associated with no cross-filling across the ACom. We propose a counter-intuitive model in which moderately elevated ICP produces greater cross-filling of the ACom. This diagnostic angiographic finding should make the angiographer consider that the patient has moderately elevated ICP, and facilitate more timely clinical management. |
