Type I and III endoleaks require urgent intervention to prevent aneurysm rupture. Intervention for other endoleaks or endotension is indicated if the aneurysm sac continues to grow during follow-up. The majority of endoleaks can be treated with endovascular techniques.
Q. 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.

Q. 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.
Q. How is endoleak diagnosed?
An endoleak is often diagnosed by noninvasive imaging tests such as a CT scan or duplex ultrasound. A Type I endoleak is usually treated with an endovascular procedure to adjust endograft placement so that the “seal zone” shifts to a healthier segment of artery.
Q. How do you treat Endoleak?
Treatments. A Type I endoleak is usually treated with an endovascular procedure to adjust endograft placement so that the “seal zone” shifts to a healthier segment of artery. In some cases, an embolization procedure is used to seal a Type I endoleak.
Q. How is Endoleak treated?
Q. Is Endoleak an emergency?
Q. Which is the most common type of endoleak?
Endoleak – Type II. 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.
Q. What’s the difference between Type III and IV endoleak?
Type III endoleak: Occurs when there is separation of overlapping stent graft components which allows pressurized blood flow to enter the aneurysm cavity. Endoleak – Type IV due to blood passing through the fabric of the graft into the sac
Q. Can a type II endoleak be followed up with CT?
Endoleaks with a stable or decreased aneurysmal sac size may be followed up with CT given the generally high rates of spontaneous resolution and a low risk of rupture in published literature 5. 1. Brown A, Saggu GK, Bown MJ, Sayers RD, Sidloff DA. Type II endoleaks: challenges and solutions.
Q. How are endobags used to treat type II endoleaks?
The hardened endobag prevents blood from flowing into the aneurysm cavity from side branches. Thus reducing the rate of Type II endoleaks. The endobags also reliably fix the stent graft in place and therefore may reduce the rate of stent graft migration.
