3 主动脉夹层动脉瘤腔内修复术 Aortic Dissection Endovascular Anuerysm Repair（EVAR）

4 主动脉夹层动脉瘤腔内修复术 Aortic Dissection Endovascular Anuerysm Repair（EVAR）
弓上分支血管重建方法 1.外科血管重建（旁路技术） 2.介入开通（烟囱技术）

5 夹层动脉瘤杂交手术弓上分支转流 Aortic Dissection Hybrid Operation with Arch Bypass
涉及主动脉弓分支的夹层动脉瘤，通过外科手术改变供血位置，可以创造出腔内修复的条件，使得腔内修复手术可以进行。 Aortic Dissection involving arch braches can be repaired with the assistance of the surgical operations alternating the vessel anatomy and creating optimal settings for endovascular repair.

6 病例资料 Cases 转流原因 Cause of bypass 同侧转流 Ipsilateral bypass 对侧转流
Contralateral bypass 弓上分支转位 Arch branch translocation 2 － 左侧优势椎动脉 Left side predominant vertebral artery 瘘口位于主动脉弓 Arch entry 1 左颈动脉动脉瘤 Aneurysm on left carotid artery Total 6 4

7 弓上分支转流方式分类 Type of aortic arch bypass
1.同侧转位 颈动脉-锁骨下动脉 目的：重建左侧优势椎动脉血流 2.对侧转位 颈-颈-锁骨下动脉 目的：重建左颈动脉\左锁骨下动脉 3.升主动脉转流 目的：重建弓上血运 1. Ipsilateral：Carotid A.-SCA. aim：to reconstruct the dominant vertebral A. 2. Contralateral： Carotid - Carotid – SCA. aim：to reconstruct LCA. \L. SCA. 3. Bypass of arch: aim：to reconstruct the arch branches

8 1.同侧转位 颈动脉-锁骨下动脉 Ipsilateral bypass: Carotid A.-SCA.
1.锁骨下动脉-颈动脉 端侧吻合 （SCA-CA: end-to-side） 2.颈动脉-锁骨下动脉 人造血管转流（CA-SCA: artificial graft bypass）

9 2.对侧转位 颈-颈-锁骨下动脉 Contralateral Bypass: CA-CA-SCA
合理的重建方法—尽量缩短颈动脉阻断时间 Ideal methods should shorten the carotid blocking time

10 2.对侧转位 颈-颈-锁骨下动脉 Contralateral Bypass：CA-CA-SCA
可能延长颈动脉阻断时间的重建方式 Styles that may prolong blocking time of carotid artery.

11 3.升主动脉转流 3. Bypass involving ascending aorta

12 弓上分支转位病例—同侧转流 Case 1: arch branch translocation (Ipsilateral bypass)

13 BYPASS Case 1

14 BYPASS Case 1

15 BYPASS Case 1

16 BYPASS Case 1

17 BYPASS Case 1

18 锁骨下动脉-颈动脉转流前后对比 Effect of Bypass
←转流前 Before Bypass 转流后→ After Bypass

19 TEVAR手术后 After TEVAR Case 1

20 锁骨下动脉-颈动脉 对端吻合(SCA-CA: end-to-end) 右位主动脉弓夹层动脉瘤 Case 2: aortic dissection with right sided aortic arch

21 Case 2 瘘口位于弓顶，食道受压，进食困难。 Entry at the top of the arch, esophagus compressed and dysphasia developed

22 双侧锁骨下动脉发自降主动脉 双侧颈动脉起自升主动脉
Bilateral SCA arise from descending aorta, bilateral carotid A. from ascending aorta. Case 2

23 Ipsilateral Bypass from SCA to CA
Case 2 锁骨下动脉-颈动脉同侧转流 Ipsilateral Bypass from SCA to CA

24 Angiography of After EVAR
Case 2 Angiography of After EVAR

25 Case 2 术后CTA 术后1个月复查CTA CTA Follow-up @ 1m after TEVAR

26 对侧转位 颈-颈-锁骨下动脉转流 Contralateral bypass：Carotid - Carotid – SCA.
颈-颈-锁骨下动脉人造血管转流 Carotid - Carotid – SCA：Artificial graft bypass

27 瘘口位于主动脉弓病例 Case 3： entry on the arch

28 降主动脉多发瘘口 左侧血胸 Multiple entry on descending aorta with left side hemothorax
Case 3

29 弓上瘘口位置 Entry on the arch
Case 3

30 瘘口位于颈动脉开口附近 Entry near Left Carotid Artery
Case 3

31 BYPASS Case 3

32 颈-颈动脉转流+左颈锁骨下动脉侧侧吻合 CA-CA bypass+L. CA-SCA side-side anastomosis

33 TEVAR Case 3

34 Closed hemothorax drainage
Case 3

35 主动脉夹层伴左侧颈动脉受累病例 Case 4: aortic dissection with left carotid artery involvement

36 瘘口位置 entry position Case 4

37 BYPASS Case 4

38 颈颈转流+颈锁骨下对端吻合 CA-CA bypass + CA-SCA end-end anastomosis
Case 4 颈颈转流+颈锁骨下对端吻合 CA-CA bypass + CA-SCA end-end anastomosis

39 总结 summary 1.颈部杂交手术可以对瘘口位于主动脉弓的夹层进行TEVAR手术 2.手术并发症发生率相对较低
3.转流方式可以根据患者情况个体化选择 4.防止并发症发生的要点是尽量缩短颈动脉阻断时间 ①Carotid hybrid operations make TEVAR procedure safe and possible for the aortic dissections with arch entries. ②With relatively low complication rate, ③the procedure can be customized for individual patient. ④Key point for complication prevention is to reduce the carotid artery blocking time as much as possible.
