1 Relationship between preoperative patency of the inferior mesenteric artery and subsequent occurrence of type II endoleak in patients undergoing endovascular repair of abdominal aortic aneurysms  Omaida C. Velazquez, MDa, Richard A. Baum, MDa, Jeffrey P. Carpenter, MDa, Michael A. Golden, MDa, Michael Cohn, MDa, Ann Pyeron, MSNa, Clyde F. Barker, MDa, Frank J. Criado, MDb, Ronald M. Fairman, MDa  Journal of Vascular Surgery  Volume 32, Issue 4, Pages (October 2000) DOI: /mva Copyright © 2000 Society for Vascular Surgery and The American Association for Vascular Surgery, a Chapter of the International Society for Cardiovascular Surgery Terms and Conditions

2 Fig. 1 Diagrams showing the distribution of patients within the various clinical protocols: (A) indications and (B) graft designs.

3 Fig. 2 Intraoperative completion arteriograms showing (A) no evidence of endoleak and (B) evidence of an endoleak. Journal of Vascular Surgery  , DOI: ( /mva ) Copyright © 2000 Society for Vascular Surgery and The American Association for Vascular Surgery, a Chapter of the International Society for Cardiovascular Surgery Terms and Conditions

4 Fig. 3 Postoperative CT scan showing (A) no evidence of endoleak, (B) evidence of endoleak of unspecified etiology (selective angiogram demonstrated this patient to have an IMA-related endoleak), and (C) an anchoring site endoleak identified by helical 3-D reconstruction CT angiogram. E, Endoleak; L, lumen.

5 Fig. 4 Postoperative ultrasound scans showing (A) no evidence of endoleak and (B) evidence of endoleak (arrow ).

6 Fig. 5 Graft indicating number of patients with endoleaks seen on completion arteriogram in the operating room versus those patients with 30-day persistent endoleaks visualized on follow-up CT scan.

7 Fig. 6 Postoperative selective SMA angiography for (A) diagnosis and (B) treatment of IMA endoleak. Arrow in A points to contrast blush into aneurysm sac immediately next to IMA, which fills retrograde through SMA collaterals. Arrow in B points to microcoils within the IMA, now obliterating the contrast blush. E, Endoleak.

9 Fig. 8 Summary of the follow-up and treatment in all patients with 30-day endoleaks.
