Type IIIB endoleak
Endoleak caused by fabric tears, suture holes, or graft porosity in endovascular aortic repair devices.
Full Definition
Type IIIB endoleak represents device-related failure in endovascular aortic repair, specifically involving the graft fabric itself through tears, suture line disruption, or material porosity. Unlike other endoleak types that involve inadequate sealing, Type IIIB indicates structural failure of the endograft material. This type of endoleak typically requires urgent intervention as it represents complete loss of aneurysm exclusion.
Usage
Usage note: Distinguish from Type IIIA (modular disconnection); both are high-risk device failures.
