Endovascular interventional treatment for the rupture of extracranial segment of carotid artery

Objective: To evaluate the efficacy and safety of the endovascular interventional minimally invasive techniques（IMIT） for treatment of rupture of extracranial segment of carotid artery.Methods: 6 cases with rupture of extracranial segment of carotid artery diagnosed by digital subtraction angiography（DSA） were treated with IMIT.Among them 4 cases were underwent transcatheter stent-graft placement to obturate the rupture of carotid artery and 2 cases underwent transcatheter embolization with coils of ruptured carotid artery.Results: Angiography demonstrated rupture of extracranial segment of carotid artery and bleeding in 5 cases,and arteriovenous fistula（AVF） at the neck in 1 case.All the cases gained successful procedure and there is no complication or mortality in the study.During the follow-up for 1 to 16 months,no symptom re-occurred（one case died of advanced cancer of neck 4 months later）.Conclusion: Transcatheter embolization and stent-graft placement are tiny invasion,safe and effective methods in the treatment for rupture of extracranial segment of carotid artery.
