Endoleak classification systems help categorize endoleaks based on their anatomical characteristics and hemodynamic impact. The most commonly used classification system is the type I to type V classification, which categorizes endoleaks according to their source and mechanism.
Type I endoleaks
occur due to inadequate sealing between the graft and the native vessel wall, leading to blood flow into the aneurysm sac. They are further classified into subtypes:
- Type Ia: Proximal seal failure
- Type Ib: Distal seal failure
- Type Ic: Combined proximal and distal seal failure
Type II endoleaks
result from retrograde filling of the aneurysm sac through branch vessels. They are commonly associated with persistent flow from the inferior mesenteric artery, lumbar arteries, or accessory renal arteries.
Type III endoleaks
occur due to graft component separation or disruption, resulting in blood flow into the aneurysm sac. They can be subclassified based on the specific site of graft disruption.
Type IV endoleaks
are characterized by the presence of microscopic pores or fabric porosity within the graft material, allowing blood flow into the aneurysm sac. They can be further subclassified based on their location and mechanism.
Type V endoleaks
involve endotension, which refers to sac expansion without any identifiable source of endoleak. It is believed to be caused by transmural pressure gradients within the aneurysm sac.
Accurate classification of endoleaks assists in determining appropriate treatment strategies and monitoring their effectiveness. By precisely identifying the type of endoleak, healthcare professionals can select the most suitable intervention modality, such as endovascular repair, embolization, or open surgical repair.
To summarize, endoleak diagnosis and classification play a crucial role in the successful management of vascular graft complications.

The choice of endoleak imaging technique depends on various factors including patient characteristics, clinical indications, and availability of resources. A multidisciplinary approach involving radiologists, vascular surgeons, and interventionalists is essential for selecting the most appropriate imaging modality for each patient.
Endoleak Detection Methods
In the field of endoleak radiology, the timely and accurate detection of endoleaks plays a crucial role in identifying potential complications and guiding appropriate treatment strategies. Various methods and protocols are utilized for endoleak detection, allowing healthcare professionals to monitor and manage vascular graft complications effectively.
One of the primary approaches to endoleak detection is the use of follow-up imaging studies, which involve periodic imaging examinations to assess the integrity of the graft and identify any signs of endoleaks. The timing and frequency of these imaging studies depend on various factors, such as the type of graft, patient-specific characteristics, and the initial presence of endoleaks.
Computed tomography angiography (CTA) is a commonly used imaging technique for endoleak detection. It provides detailed, high-resolution images that allow for the visualization of both the graft and any potential endoleaks. By using intravenous contrast material, CTA can accurately identify the presence, location, and severity of endoleaks.
Magnetic resonance angiography (MRA) is another imaging modality used to detect endoleaks. MRA utilizes magnetic fields and radio waves to create detailed images of blood vessels. Although it doesn’t involve radiation exposure like CTA, MRA may not be suitable for patients with certain contraindications, such as the presence of metal implants.
Duplex ultrasound is a non-invasive imaging technique that uses high-frequency sound waves to visualize blood flow. It is particularly useful for assessing endoleaks in the abdominal aortic region. Duplex ultrasound allows for real-time imaging and can provide valuable information on the presence and flow characteristics of endoleaks.
Table:
