How often is a perimesencephalic subarachnoid haemorrhage CT pattern caused by ruptured aneurysms?
Acta Neurochirurgica
|January 1, 1993
Summary
Angiography is recommended for perimesencephalic subarachnoid hemorrhage (PM SAH) to detect aneurysms. However, the study found a low likelihood of aneurysms in PM SAH patients, suggesting careful consideration of diagnostic imaging.
Area of Science:
- Neurology
- Radiology
- Neurosurgery
Background:
- Perimesencephalic subarachnoid hemorrhage (PM SAH) diagnosis often involves angiography to exclude basilar artery aneurysms.
- The frequency of aneurysms in patients with CT-confirmed PM hemorrhage and the occurrence of PM CT patterns from posterior circulation aneurysms are not well-established.
