This complaint is from a literature source.As reported in the literature publication entitled, ¿outcomes of type 2 endoleaks detected on venous phase ct arteriography.¿ 4 patients after endovascular aneurysm repair (evar) who complicated with type 2 endoleak (t2el) and who underwent endoleak embolization with a combination of platinum coils and nbca liquid embolic agent -trufill experienced aneurysm recanalization, , which was treated surgically by open repair.Purpose: the majority of type 2 endoleaks (t2el) are identified on computed tomography angiography (cta) both on arterial and venous phase.There is a subset of t2el that are demonstrated only on venous phase cta.This study was done to report the outcomes of t2el detected only on venous phase cta.Materials and methods: between october 2001 and june 2015 a total of 261 consecutive t2el treated via embolization were reviewed for the presence of endoleak demonstrated only on venous phase cta.A group of 16 patients (12 men, 4 women; mean age, 80.1 years) was identified who had pre-embolization venous phase t2el.Patients were evaluated for presence of t2el after embolization, change in aneurysm diameter, and need for further intervention.
