【摘要】目的 評估分支TEVAR技術治療復雜主動脈弓部病變的近期療效。方法 回顧性分析天津醫科大學總醫院2016年4月至2018年12月應用分支TEVAR技術治療的18例需重建左鎖骨下動脈的主動脈病變患者的圍手術期及隨訪資料。結果 置入Castor外分支支架16例，自制內分支支架2例，器械釋放成功率100%，手術成功率100%，無術中死亡病例。術后并發癥2例：支架近端逆撕夾層1例（行開放手術）、大面積心梗1例（死亡）。 17例患者獲得隨訪，隨訪時間1~8個月。 術后第30天16例CTA檢查1例發生III型內漏，分支支架血流通暢。術后6個月8例CTA檢査無內漏,1例左鎖骨下動脈支架遠端閉塞,予遠端置入支架解決，無新發死亡病例。結論 分支TEVAR技術是重建弓上分支動脈的有效方法。

【摘要】目的 探討應用Castor分支型主動脈覆膜支架治療健康錨定區不足15mm的Stanford B型主動脈夾層(TBAD)的臨床效果。方法 回顧性分析解放軍第九七O醫院2017年10月至2018年6 月應用Castor單分支型支架治療18例近端健康錨定區<15 mm的TBAD患者的臨床資料，其中急性TBAD17例，慢性TBAD1例，患者均經CT血管成像(CTA)確診。結果 手術成功率100%，手術平均 時間(127.8±20.1)min，均無內漏發生，圍術期無腦梗死、夾層動脈瘤破裂等并發癥，無死亡病例。術中2例左鎖骨下動脈(LSA)分支支架釋放后存在狹窄，給予球囊擴張后狹窄解除；1例術后出現左側肱動脈穿刺點血腫，經保守治療治愈。隨訪18例，平均隨訪時間(8±2)個月，無截癱及死亡病例，LSA分支支架通暢率為100%，無內漏及夾層逆撕，胸主動脈段真腔直徑較術前明顯擴大、假腔直徑較術前明顯縮小(P<0.05)，胸段假腔術后血栓化率高于腹主動脈。結論 Castor分支型覆膜支架治療近端健康錨定區不足15mm的TBAD可以有效重建LSA，操作安全精準，隔絕效果好，短期隨訪無內漏發生，遠期療效尚需進一步觀察。

【摘要】 目的 總結單分支型主動脈支架在Stanford B型主動脈夾層的腔內隔絕治療經驗。方法 2013年7月至2014年2月復旦大學附屬中山醫院血管外科對11例近端破口距離左鎖骨下動脈開口<20mm的Stanford B型主動脈夾層應用一體化單分支型主動脈支架行腔內隔絕治療，觀察術后即時血管造影結果、術后1個月門診隨訪、術后6個月行主動脈CT血管造影(CTA)檢查。以動脈瘤相關存活率、手術成功率和分支支架通暢率為有效性終點指標，并觀察相應的不良事件。結果 11例中10例術中支架釋放成功，1例分支支架無法進入左鎖骨下動脈而放棄。平均手術時間(130.0±36.0)min，圍手術期無不良事件。隨訪期10例病人中無死亡，1例出現支架遠端內漏，1例出現左鎖骨下動脈支架閉塞，余支架封堵良好，夾層假腔均出現血栓化，假腔直徑平均縮小12mm。 結論 單分支型主動脈支架對于近端破口距左鎖骨下動脈開口<20 mm的Stanford B型主動脈夾層是有效的腔內隔絕方法。

【摘要】Objective To report the early results of castor device, a kind of unibody single-branched stent graft, in the treatment of type B aortic dissection (TBAD) involving the LSA. Methods From April 2013 to February 2014, 21 patients with TBADs underwent TEVAR with LSA revascularization by unibody single-branched stent grafts. Three patients with penetrating aortic ulcers in the aortic arch received additional reconstruction of left common carotid artery with chimney technique. Follow-up evaluations were conducted with computed tomography angiography (CTA) at 6, 12 months and annually after that. Results All of the proximal entry tears were completely excluded. Good patency of the grafts was found in all cases. A small type I endoleak occurred in one patient during the procedure. Perioperative mortality is null, and there was no occurrence of serious complications. All patients completed the follow-up except one lost contact after discharge. One death occurred within 6 months after the operation, resulting from myocardial infarction, considered unrelated to the stent implantation. No endoleak occurred during follow-up. One compression of a chimney stent and one twist of side branch graft of castor were observed in 2 different patients, respectively. In other cases, CTA scans showed good patency of both the branched and chimney grafts. Two patients had partial thrombosis of the false lumen during follow-up. In other patients, complete thrombosis in the false lumen in thoracic aorta was revealed. Conclusion The single-branched stent graft was safe and efficient in the 1-year follow-up. Further studies are required to determine its long-term outcomes.

【摘要】Background: The present study retrospectively reviewed and evaluated the effectiveness of thoracic endovascular aortic repair (TEVAR) combined with assistant techniques and devices for the treatment of acute complicated Stanford type B aortic dissections involving aortic arch. Methods: Fifty-six patients with acute complicated Stanford type B aortic dissection involving aortic arch were treated with TEVAR combined with hybrid procedure, chimney-graft technique, and branched stent grafts from January 2009 to March 2014. Results: Seventeen patients undergone TEVAR combined with hybrid technique. Technical success was achieved in 94.1% with 5.8% of early mortality. Strokes occurred in a patient developing paraplegia, who completely recovered after lumbar drainage. Cardiocirculatory and pulmonary complications, bypass dysfunction or severe endoleak was not observed. Thirty patients undergone TEVAR combined with chimney technique with 100% technical success rate. Chimney-stent compression was observed in 1 patient, and another bare stent was deployed inside the first one. Three patients (10%) died during the study period. Immediate postoperative type I endoleak was detected in 4 cases (13.3%). TEVAR assisted by Castor branched aortic stent grafts in 9 patients was successful. Mortality during perioperative period and 30 days after TEVAR was null. No serious complications such as strokes, acute myocardial infarction, and ischemia of arms occurred. Conclusions: The results indicate that TEVAR combined with hybrid technique, chimney technique, and branched stent grafts is proven to be a technically feasible and effective treatment for acute complicated Stanford type B aortic dissection involving aortic arch in small cohort.

【摘要】Objective: There is no approved special endovascular device for use in preventing entry tears in the distal part of ascending aorta or in the aortic arch and preserving the arch branch arteries. Thus, we have designed a novel branched stent-graft, and herein report the initial clinical outcomes. Methods: Between August 2009 and January 2014, 51 patients with aortic dissections involving the aortic arch were treated by endovascular branched stent-grafts. There were 7 Stanford type A aortic dissections, 22 retrograde type A aortic dissections, and 22 Stanford type B aortic dissections (including 4 localized aortic arch dissections). All patients were treated while in the chronic phase (>2 weeks). Results: All of the proximal entry tears in the arch were successfully excluded, and all of the treated branch arteries remained patent. No new cerebral infarction occurred. There was 1 death from a retrograde type A dissection, occurring 6 days after the endovascular procedure. The median follow-up period was 44 months (range, 14-66 months). No additional complications or mortality occurred. Complete thrombosis in the false lumen of the aortic arch was formed in all patients, and significant true lumen recovery and false lumen shrinkage were demonstrated in different levels of the thoracic aorta according to computed tomography angiography at 1 year postsurgery (P<.001). Conclusions: In patients with aortic dissection involving the arch branches, the customized branched stent-graft may provide a feasible endovascular treatment option. A larger series of cases with longer follow-up is needed to substantiate these results. (J Thorac Cardiovasc Surg 2015;-:1-8)

【摘要】慢性A型夾層合并Kommerell憩室患者的腔內治療依然充滿挑戰，這是我們首次報道慢性夾層逆撕為A型夾層的腔內治療。我們采用一體化單分支支架+煙囪技術針對2支鎖骨下動脈進行重建。術后造影提示第一破口被完全隔絕，一體化支架及煙囪支架血流通暢，隨訪期間檢查CTA提示真腔顯著重塑。通過此例患者，我們發現腔內技術在此類患者的治療中是安全和可行的。
