Abstract:
The role of interventional neuroradiology in the management of skull base tumours and related surgical complications. The management of hypervascular skull base tumours is complex and requires a multidisciplinary approach. Skull base surgery may be challenging because of the risk of serious intra-operative bleeding and of potential injuries to lower cranial nerves and/or large cervical vessels. Over the last four decades, advances in neuro-interventional procedures have produced a range of adjunctive endovascular techniques in addition to conventional surgery. Digital sub- traction angiography (DSA) allows for a better understanding of tumour vascularisation and its relationship with surrounding vessels. Tumoural devascularisation and the occlusion of feeding arteries is a useful adjunct to surgery because it allows for the reduction of intra-operative blood loss and induces ischaemic necrosis of the tumour. Finally, 4 surgery-related iatrogenic vascular lesions may be successfully treated with endovascular techniques.vertheless, endov5,6ular procedures in the head and neck region are associated with infrequent but potentially serious complica- tions. An extensive and comprehensive knowledge of head and neck vascular anatomy is therefore necessary. This article provides a review of the indications for, and results of, diagnostic, pre-operative and therapeutic endovascular procedures for the management of skull base tumours and related surgical complications.
