Abstract:
Objective To discuss the application of bare-stent“chimney”technique in treating aortic dissection associated with left common carotid rupture, and to evaluate its therapeutic effect. Methods The clinical data of 7 patients with aortic dissection accompanied with left common carotid rupture, who were admitted to Qinghai Provincial People’s Hospital during the period from February 2012 to March 2014 to receive endovascular isolation operation treatment with bare-stent “chimney” technique, were retrospectively analyzed. When the rupture of aortic dissection was occluded with covered-stent, the left common carotid rupture was isolated with “chimney”bare-stent to reconstruct the blood flow of left common carotid artery. CT angiography was performed 2 weeks after the operation to check if there was any complication such as endoleak, stent migration, etc. Results The technical success rate of endovascular isolation operation was 100%. No type I endoleak occurred. The patients were followed up for 1-13 months, the covered stent in the aorta was in good position, and the “chimney” bare-stent in the left common carotid artery was patent. No complications such as endoleak, stent migration, etc. occurred. Conclusion Bare-stent“chimney”technology can provide treatment opportunity for the patients suffering from left common carotid artery rupture accompanied by aortic dissection; the rupture can be completely obstructed and the blood flow can be reconstructed. The short-term effect is satisfactory, although the long-term effect needs to be further studied.
