What is a Type II endoleak?

What is a Type II endoleak?

Type II endoleak: Type II endoleaks are the most common. These are leaks that happen when blood flows into the aneurysm sac from branches of the aorta, or other blood vessel treated with a stent. The blood flows into the aneurysm sac cavity through small branches which enter the treated aneurysm.

How long can you live with an endoleak?

A total of 52 patients (24%) who underwent EAR had endoleak detected during postoperative follow-up, which averaged 19 months (range, 0.4–101 months). One, 6-, 12-, and 24- month endoleak-free survival was 90%, 80%, 77%, and 73%, respectively.

How serious is an endoleak?

Occasionally, blood will still flow into the aneurysm sac even after a stent graft is in place; this flow, called an endoleak, can become potentially life threatening. Our interventional radiologists are specialists in endoleak repairs and treatment of the areas of the body in which the repairs take place.

How many types of endoleaks are there?

There are 5 types of endoleaks, each with different causes and treatment options.

When do you treat type 2 endoleak?

At Miami Cardiac and Vascular Institute, type II endoleaks are only treated if there is evidence of aneurysm growth (generally > 5 mm). There are multiple approaches to the management of these endoleaks, including transarterial, translumbar, transcaval, and surgical approaches.

Which Endoleaks should be fixed?

Type I and type III endoleaks represent direct communication with the systemic blood flow and the aneurysm sac and require immediate repair.

Is an endoleak an emergency?

Although it is a rare complication in third-generation stent grafts, type III endoleaks need to be seen as an emergency, because they lead to repressurization of the aneurysm sac and a ninefold higher risk of secondary rupture.

How long can you live with an aortic stent?

Current generation stent grafts correlated with significantly improved outcomes. Cumulative freedom from conversion to open repair was 93.3% at 5 through 9 years, with the need for prior reintervention (OR, 16.7; P = 0.001) its most important predictor. Cumulative survival was 52% at 5 years.

Can a repaired aneurysm leak?

Reports in the literature (,1,,2) indicate that leaks after the endovascular treatment of aneurysms occur in 3%–44% of patients. Leaks may originate at both the proximal and distal ends of the graft. These are so-called perigraft leaks, according to the classification by White et al (,3).

How do you detect Endoleak?

Endoleak is seen on CT angiography (most common modality for follow up and investigation of potential endoleaks), MR angiography and DSA as contrast opacification of the aneurysm sac outside the graft. Flow in the sac may also be detected on ultrasound.

Can a stent leak?

Endovascular stent grafts can sometimes leak blood through the areas where the graft components join together, or they can allow blood to leak back into the aneurysm sac through small arteries feeding the aneurysm sac. These leaks are called “endoleaks”. Some of the leaks stop by themselves and are not dangerous.
