Angiogram Negative Subarachnoid Haemorrhage: The Role of Repeat Angiography
Vedat AÇIK1,Semih Kıvanç OLGUNER1
1Adana Şehir Hastanesi, Nöroşirürji Kliniği, Adana, Türkiye Aneurysmal subarachnoid hemorrhage (SAH) has a high rate of mortality and morbidity. A number of patients with SAH on cranial computed tomography (CT) have been found to have no pathology on vascular imaging studies. In some of these patients, the hemorrhage was located in the perimesencephalic region and had a benign course. In other patients, the SAH was diffuse and could have a malignant course. Vascular pathologies may not be detected in patients with a diffuse SAH on the first angiography due to vasospasm or thrombus and small lesions may cause rebleeding. In order to prevent such conditions, angiographic imaging should be repeated. At the same time, it should be kept in mind that spinal vascular pathologies and pathologies that are not detected on angiography such as cavernomas may lead to subarachnoid hemorrhage. Spinal and cranial magnetic resonance imaging should be requested from patients to detect spinal and cranial vascular pathologies.
