Type III and type IV endoleak: toward a complete definition of blood flow in the sac
after endoluminal AAA repair. J Endovasc Surg 1998;5:305309.
“If the endoleak continues to be present on the 6-month scan, there is a small chance that it will spontaneously thrombose”
6-month CT scan
Blood enters during systole into the endoleak cavity, swirling around, leaving the endoleak cavity during diastole
Physiology similar to
May spontaneously thrombose prior to the 6-month CT scanENDOLEAK ANATOMY“Simple”
The endoleak cavity acts as an “Arteriovenous malformation nidus,” and thrombosing this nidus is what provides a successful and durable response.
