[Microsurgical treatment of large and giant aneurysms of the internal carotid artery: analysis of application of intravascular blood aspiration technique and future perspectives].

Abstract The article discusses results of surgical treatment of 82 patients with large and giant cerebral aneurysms operated in Burdenko Neurosurgical Institute (Moscow, Russia) during the recent 14 years. Special attention was given to benefits of intravascular blood aspiration (IBA) technique. This technique was proven to be very effective, allowing to clip the aneurysm in 87.8% of cases with good recovery in 41.5% and with moderate disability in 39%. Postoperative mortality was 4.9% (4 patients). The authors suggested original surgical classification of large and giant aneurysms. IBA was ineffective in cases of giant partially thrombosed aneurysms with sclerotic walls and giant aneurysms with very wide neck. These aneurysms require other surgical procedures such as embolization of ICA followed by extraintracranial bypass or high-flow bypass.
