Management of a heavily calcified atherosclerotic occlusive disease involving the common femoral artery (CFA) and external iliac artery (EIA), poses a surgical challenge. Though the current guidelines recommend open surgical therapy for such lesions, this approach is neither easy nor represents the current real-life practice.
To describe tips and tricks facilitating the hybrid technique for the management of distal iliofemoral atherosclerotic disease, where classic endarterectomy is inadequate or ill-performed.
A contralateraly inserted guidewire reaches the distal iliac artery via the crossover technique and is directly retrieved from the femoral arteriotomy immediately after removal of the anterior plaque segment. The retrieved and secured guidewire enables extensive retrograde CFA endarterectomy over the wire with avusion proximally to the inguinal ligement, followed by patch arterioplasty. Externalizing the guidewire from the patch enables traction on it and facilitates advancement of the stent through tortuous or stenosed iliac vessels as well as accurate stent deployment to cover the margin of the EIA residual plaque. Moreover, this manipulation enables ipsilateral placement of a sheath and passage of a second, retrograde guidewire to perform kissing stenting in the common iliac vessels. Chronic thrombotic lesions require covered stents to avoid thrombus propagation and meticulous flushing before completion of the femoral patching.
The combined iliofemoral endarterectomy with stenting does not require advanced endovascular skills and prevents complications associated with incomplete femoral endarterectomy. Extensive avulsion endarterectomy proximal to the inguinal ligament is efficiently and safely performed over a retrieved crossover guidewire, enabling precise residual stenting above the flexion site.
涉及股总动脉(CFA)和髂外动脉(EIA)的严重钙化粥样硬化闭塞性疾病的管理带来了手术挑战。尽管目前的指南建议对这些病变进行开放手术治疗,但这种方法既不容易,也不符合当前的实际情况。
描述便于杂交技术管理远端髂股动脉粥样硬化疾病的技巧和窍门,其中经典的内膜切除术是不充分或执行不佳的。
通过交叉技术将对侧插入的导丝到达远端髂动脉,并在从前斑块段切除后立即从股动脉切开处直接取回。取回并固定的导丝使能够在导丝上进行广泛的逆行 CFA 内膜切除术,在腹股沟韧带近端进行切开,然后进行补片血管成形术。将导丝从补片外部化可对其进行牵引,并便于在迂曲或狭窄的髂血管中推进支架,以及准确地部署支架以覆盖 EIA 残余斑块的边缘。此外,这种操作可以在同侧放置护套并通过逆行导丝进行第二次逆行导丝以在髂总血管中进行亲吻支架。慢性血栓性病变需要使用覆盖支架以避免血栓传播,并在完成股部补片之前进行仔细冲洗。
联合髂股动脉内膜切除术和支架置入术不需要先进的血管内技术,并可预防与股部内膜切除术不完全相关的并发症。在取回的交叉导丝上进行腹股沟韧带近端的广泛切开内膜切除术,可有效地、安全地进行,使精确的残余支架位于弯曲部位上方。
