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

NCT04941846 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 296

No results posted yet for this study

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.
