Brief summary
Aim:Castor is a novel single-branched stent graft system for endovascular repair of aortic arch dissection. This is a prospective, one-arm, open, multi-center, pre-market study of Castor stent to evaluate its efficacy and safety in treatment of aortic dissection. Number of patients: 70 patients will be included and undertaken endovascular repair with Castor stent. Follow-up: 1.aortic computed tomographic angiography (CTA) examination 6 and 12 months after the surgery 2.telephone or clinical follow-up 30 days and 2-5 years after the surgery Primary Outcome Measure: success rate of endovascular repair for efficacy measurement. Secondary Outcome Measure: 1 year stent related adverse event rate for safety measurement. Other Outcome Measures: 1. efficacy: * 1 year success rate of treatment * 1 year patency rate of branch stent 2. safety: * in-hospital mortality * complication rate of neural system * 1 year dissection or stent related mortality

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| success rate of endovascular repair | during the surgery | \- during the surgery: successful conduction, accurate positioning and release, and no warping, folding, narrowing or blocking of the stent graft system. Immediately after the stent release, angiography shows both main stent and side arm stent patency, successful exclusion of dissection and no arteriorrhexis or dissection rupture. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 1 year stent related adverse event rate | 1 year | * unexpected breakage and shifting of the stent * type I or type III endoleak which needs intervention * dissection rupture around the stent |
Other
| Measure | Time frame | Description |
|---|---|---|
| in-hospital mortality | participants will be followed for the duration of hospital stay, an expected average of 1 week | mortality of patients caused by dissection related postoperative complications before discharge. |
| 1 year success rate of treatment | 1 year | * complete exclusion of the dissection * no dissection rupture * no type I or type III endoleak which needs twice intervention * false lumen of aorta around stent graft closed with thrombus |
| 1 year dissection or stent related mortality | 1 year | 1 year dissection or stent related mortality |
| complication rate of neural system | 2 years | complication rate of neural system related to the stent graft |
| 1 year patency rate of branch stent | 1 year | The incidence of more than 50% branch stent patency |
