Fig. 1 Maximal transverse diameter of aneurysm after endovascular exclusion of AAA. Measurement by CT and duplex scan correlated closely (r, –0.93; P <.001), and on paired t test no significant difference was found. In 92% of the scans, diameter measurements differed by less than 5 mm.

Fig. 2 CT (A) and duplex scan (B) demonstrating an endoleak curving along the posterior wall of the aneurysm. Selective arteriography (C) demonstrates the lumbar artery feeding this endoleak.

Fig. 3 An endoleak originating at the proximal attachment site within a narrow space posterior to the proximal portion of the endograft is difficult to discern on CT (A). The space is nicely demonstrated on gray scale ultrasound scan (B), and endoleak flow is seen on color flow duplex scan (C). Aortography (D) demonstrates contrast alongside and to right of the proximal portion of the graft.
