Result of neck clipping and coil embolization as a treatment for subarachnoid haemorrhage

The report of the International Subarachnoid Aneurysm Trial (ISAT) study showed that coil embolization was superior to neck clipping as a treatment for subarachnoid haemorrhage (SAH). We compared the results of coil embolization and neck clipping in our institute. Generally better outcomes were obtained by endovascular surgery than neck clipping. Symptomatic vasospasm and symptomatic hydrocephalus occurred less frequently in coil embolization than neck clipping. Because not all cas es of SAH can be treated by coil embolization due to the width of aneurysmal neck and relation of the aneurysm to parent arteries, we should also be able to perform neck clipping as another modality.
