[Treatment of cranial-cervical aneurysms with stent-graft: 20 cases report with short-term follow-up].

OBJECTIVE: To investigate the therapeutic effect of cranial-cervical aneurysms with stent-graft.

METHODS: Clinical data of 20 patients with cranial-cervical aneurysm treated with stent-graft in Department of Neurosurgery, Tangdu Hospital, Fourth Military Medical University from November 2006 to November 2015 were retrospectively analyzed. There were 15 male and 5 female patients with a mean age of 40 years (ranging from 22 to 67 years). There were 10 spontaneous cases, 5 trauma history cases and 5 surgery history cases. Postoperative follow-up were made by telephone, CT angiography or digital subtraction angiography, evaluating therapeutic effect.

RESULTS: Twenty-four stent-grafts placement were carried out in 20 patients and all of them were successfully deployed in the parent artery. Intraoperative stent malapposition induced endoleak occurred in 3 cases, incomplete coverage of distal stent segment in 2 cases, acute thrombosis in 1 case and vessel lesion in 1 case. Eighteen cases were radiographically cured while the other 2 cases improved through additional stent placement, coil embolization or artery thrombolysis. Clinical symptoms of post-operative patients were improved to varying degrees. Follow-up of 1 to 96 months (average of 19 months) were accomplished. Delayed parent artery occlusion were encountered in 2 cases while endoleak still existed in 1 case.

CONCLUSION: Application of stent-graft for cranial-cervical aneurysms is safe and effective and the short-term follow-up results are satisfied.
