A Case of Successful Coil Embolization for a Late-Onset Type Ia Endoleak after Endovascular Aneurysm Repair with the Chimney Technique

الملخص EN

Juxtarenal aortic aneurysms (JRAAs) are challenging to treat by endovascular aneurysm repair (EVAR) procedures.

The chimney technique with EVAR (Ch-EVAR) is one of the feasible and less invasive treatments for JRAAs.

However, the main concern of Ch-EVAR is the potential risk of “gutters,” which can lead to type Ia endoleak (EL).

Most type Ia ELs after Ch-EVAR procedures occurred intraoperatively, and these ELs could be treated using an endovascular technique.

However, late-onset type Ia ELs could be extremely rare, which might have a fear of conservative treatment.

Type Ia ELs are associated with an increased risk of aneurysm rupture; therefore reintervention is recommended as soon as possible, and we should be aware of the occurrence of type Ia ELs after the Ch-EVAR procedure.
