Clinical Applications Of Endovascular Graft Exclusion For Stanford Type B Aortic Dissection

OBJECTIVE: The aim of this study was to summarize clinicalexperience of endovascular graft exclusion for Stanford type B aorticdissection.METHODS: A retrospective analysis about47cases after EVGE wasconducted at department of cardiothoracic surgery from June2007toSeptember2013. CT angiography (CTA) was used preoperative for thediagnosis and assessment, and digital subtraction angiography (DSA) wasconducted as a guidance of EVGE to endovascular aortic dissection.Follow-up assessment were conducted after one month, three months, halfyear and once a year to learn about the blood pressure, tumormorphological changes, a variety of adverse events, complications, andsurvival rate and so on.RESULTS: Forty-seven patients with stanford type B aorticdissection were included in the study.97.87%(46/47) cases weresuccessfully released after surgical and there was no perioperative deaths; Postoperative endoleak was found in3cases, one patient died due to aorticesophagus fistula, and the death rate was2.13%; One case had cerebralinsuffizienz, but the symptoms disappeard after conducted the carotidartery-left subclavian artery bypass. Overall postoperative complicationrate was8.51%. The remaining patients didn’t occur any complicationsabout the artery dissection and surgery and had a good overall quality oflife.CONCLUSIONS: Endovascular graft exclusion for stanford type Bdissection have a high success rate, easy operation, and low perioperativecomplications and mortality; Which is a safe, minimally invasive andeffective treatment methods.
