Background:
Tumours of the parasellar area may engulf the internal carotid artery(ICA) and its branches which may preclude complete resection and may be a risk factor for ischemic complications.
Methods:
We present a surgical technique based on a stepwise identification of the arterial branches which may enable a complete resection in selected cases even when complete encasement of the ICA is present on preoperative images.
Conclusion:
Resection of tumours encasing the major vascular structures should be systematically attempted while continuously weighing the delicate balance between the risk of vascular injury and the extent of resection.
