What is a Type 3 endoleak?
Type IIIa endoleak is described as a disconnection between the main body and the contralateral limb but can also be due to disconnection of the iliac limb from the ipsilateral distal extension or of a proximal cuff from the endograft main body.
What is the most common type of endoleak?
Type II: The most prevalent type of endoleak stemming from an increase in pressure in the side branches of the aorta that push blood back into the less pressure-filled aneurysm sac, this type of endoleak is generally harmless although its behavior is often unpredictable.
What are symptoms of an endoleak?
Endoleaks typically don’t cause any noticeable symptoms. However, if the leaking blood causes the aneurysm sac to expand to the point where it ruptures, it can become a life-threatening emergency.
How long can you live after TAA surgery?

How long can you live with a leaking AAA?
Median survival was 18 (range 1-90) months. Twenty (35 per cent) suffered rupture at a median interval of 18 (range 1-38) months. The risk of rupture within 3 years was 28 (95 per cent confidence interval 12-49) per cent for 5.0-5.9-cm AAAs and 41 (24-59) per cent for AAAs of 6 cm or greater.
What is a type III endoleak?
A type III endoleak (EL) is the consequence (open arrow). • Type IV ELs: These types of ELs are caused by graft porosity. The phenomenon of angiographic blush can be observed during the immediate postimplantation angiogram.
What is the prevalence of Type III endoleak after EVAR?
Type III endoleak rarely (2.1%) occurs after EVAR, with a higher incidence in first- and second-generation endografts. In the majority of cases, the underlying mechanism is disconnection of the stent graft components. Type III endoleaks may occur early or late after initial EVAR and can, in most cas …
What is a type 2 endoleak on CT scan?
FIGURE 50-1 A-D, Axial computed tomography (CT) slices show a proximal type I endoleak (EL) (small arrows) that resulted in aneurysm rupture. Retroperitoneal hematoma can be seen clearly (open arrows). • Type II ELs: These ELs are also called reperfusion leaks.
What is the classification of endoleaks?
Classification of Endoleaks Type I Attachment site leak A Proximal B Distal C Iliac plug in aortouniiliac stent-grafts Type II A Reperfusion leak
