An alternative system for cerebrovascular reconstructions: non-penetrating arcuate-legged clips

Non-penetrating, arcuate-legged titanium clips (VCS) have been utilized successfully over the past five years for a variety of cerebrovascular reconstructions. These applications, including both micro and macrovascular reconstructions, their clinical outcomes and technical considerations are described. Applications include patch angioplasty of cervical carotid endarterectomies, superficial temporal to middle cerebral artery 'bypass' procedures, Takayasu's arteritis and cavernous carotid reconstructions. The non-penetrating clip has proven to be a safe and reliable alternative to suture for these demanding reconstructions. Clips provide the advantages of improved anastomotic compliance, reduced operative time, and reduced incidence of post-operative anastomotic intimal hyperplasia and stenosis. Clip related pitfalls are discussed with recommendations regarding usage.
