The Role of Deep Cerebral Vein Variation in Patients With Angiographic Negative Subarachnoid Hemorrhage

Subarachnoid Hemorrhage, Aneurysmal Clinical Trial

Official title:
The Role of Deep Cerebral Vein Variation in Patients With Angiographic Negative Subarachnoid Hemorrhage

Clinical Trial Summary

The incidence of Rosenthal basilar vein (BVR) variants (deep venous drainage variants) was relatively increased in patients with AN-SAH compared with patients with aneurysms. However, the inclusion criteria for AN-SAH patients in these studies were different. Some studies have investigated both PAN-SAH and NPAN-SAH, while some studies have only investigated PAN-SAH patients. However, we believe that NPAN-SAH may be the bleeding caused by non-BVR variation. Although previous studies did not find any association between NPAN-SAH and BVR variants, the results in their study were different, which may be due to the limited number of cases.
