Common iliac artery

Find and hold common iliac artery as recognized as downwards Y shape, down the kidney and trim adhered tissue around the aorta and go up by cutting off artery branches. 

The advance of endovascular therapy for aorto-iliac aneurysmal disease has also brought about yet another flourishing application of embolotherapy. Embolization of the internal iliac artery plays an important adjunct initial modality to allow endovascular treatment of aortic aneurysms with extension into the common iliac arteries [78-80], It also plays an crucial role in the secondary management of complications related to endoleaks [81-84],... 

An alternative way of catheterizing the uterine artery using selective catheters is described by Andrews [30]. Following an aortogram, the flush catheter is used to direct a wire over the iliac bifurcation. A 4-F Berenstein catheter (or another selective catheter such as a C2) is then placed into the contralateral common iliac artery. Repeat imaging... 

Type IC leaks occur in cases where an aorto-uni-iliac stentgraft has been deployed, in conjunction with a femoral-femoral bypass graft. An occluder device is then placed in the contra-lateral common iliac artery. Its function is to prevent back filling of the aneurysm from the excluded common iliac artery. The treatment of these leaks requires completion of the intended thrombosis of the common iliac artery. Embolization is the simplest way to complete this, either by passing the occluder and embolizing cranial to it, or, by placing a second occluder device caudal to the original device. 

The occlusion of the iliac artery is usually sufficient to treat the leak. However, in cases of long-term type IC endoleak, many outflow vessels may have developed and the leak may communicate with multiple lumbar arteries and the IMA. These enlarged vessels might be source of late type II endoleak. Thus, we usually embolize both the outflow vessels and the sac before occluding the iliac artery. Another attractive technique to achieve the occlusion of the common iliac artery is to perform an endovascular internal to external iliac artery bypass using stentgraft. This technique can allow the exclusion of the common iliac preserving the internal iliac artery. 

As mentioned above, status of the internal iliac arteries is an important anatomic consideration in the treatment of aortoiliac aneurysms. Indications for embolization of IIA in association with EVAR include aneurysm of the IIA or ectatic or aneurysmal common iliac artery (CIA) involving the origin of IIA. Additionally, extension of stent-graft into the external iliac artery (El A) may become necessary if the CIA is judged to be too short for adequate or safe anchoring of the device or if there is a distal type-I endoleak. This will lead to loss of antegrade flow in the IIA.

Fig. 2. Significant stenosis in peripheral arteries. (A) Stenosis in the common iliac artery. Both the peak systolic and end diastolic velocities are significantly increased. The V2I 1 was 3.9 (456/117) indicating a >50% diameter stenosis. (B) Stenosis in the anterior tibial artery. The prestenotic (36 cm/s) and the poststenotic (145 cm/s) velocities are obtained to estimate the V2/V1 ratio (4.0).
