2023年6月12日 · An endoleak is a common complication of EVAR and is found in 30-40% of patients intraoperatively (seen on the on-table angiogram after stent deployment), and in 20-40% during follow-up. It has been referred to as the “Achilles' heel” of the endovascular approach to aneurysm treatment.

Endoleaks may be identified on completion arteriography at the time of endovascular aneurysm repair (EVAR) or during later follow-up at the time of endograft surveillance imaging. The type of endoleak, classified as type I through type IV, determines its clinical significance and treatment.

A type 1 endoleak happens when the stent graft isn’t properly attached to your artery wall. Blood leaks around the top or bottom of your stent graft. Type 1 endoleaks are serious and usually need treatment immediately. They have a higher risk of rupturing than other endoleak types. Type 2 endoleak. Type 2 endoleaks are the most common type ...

2023年1月23日 · Endoleaks occur when an aneurysmal sac continues to be pressurised despite endoluminal stent placement. See the full article on endoleaks here. Classification. There are five types: type I: leak at graft ends (inadequate seal) - most common after repair of thoracic aortic aneurysms 4. Ia: proximal; Ib: distal; Ic: iliac occluder

Similar to T1a endoleaks, the leading determinant of T1b endoleak risk is the quality of the distal seal between the endograft and the native common iliac or external iliac arterial wall. Prevention of a T1b endoleak is made difficult if there are anatomic features such as aneurysmal iliac arteries, tortuosity of the iliac arteries, and short ...

2019年4月24日 · Type 1b endoleak is associated with an increased aortic tortuosity index (>0.15 cm −1). No significant difference is found in relation to age and gender. Treatment is required in most cases (22/27) and is usually performed with distal extension of the stent graft (21/27).

2012年11月23日 · An endoleak is one of the most common complications of EVAR and may progress to aneurysm rupture. A classification system has evolved for endoleaks (Figs. 1A, 1B, 1C, and 1D), and classification of a particular endoleak then implies a relatively high or low short-term risk of rupture and determines the urgency of intervention.

Type 1b endoleak is caused by an inadequate seal at the distal landing zone. Late type 1b endoleaks are reported in 2.3% at a mean follow-up of 32.8 months [ 10 ]. Similar to EL1a, EL1b are associated with an increase in sac size and aneurysm rupture.

An endoleak refers to persistent blood flow within the aneurysm sac following an endovascular aneurysm repair (EVAR) procedure —one of the procedure’s most common complications. Usually an endoleak causes no symptoms at all. Often, an endoleak is found during a routine follow-up visit with your vascular surgeon after you have had an EVAR procedure.

Endoleak type 1B is a specific complication that can occur after aortic repair in patients with abdominal aortic aneurysm (AAA). It is important to have a clear understanding of this condition and its implications for effective treatment and patient management.
