1 Open repair versus endovascular treatment for asymptomatic popliteal artery aneurysm: Results of a prospective randomized study  Michele Antonello, MD, Paolo Frigatti, MD, Piero Battocchio, MD, Sandro Lepidi, MD, Diego Cognolato, MD, Alberto Dall’Antonia, MD, Rudi Stramanà, MD, Giovanni P. Deriu, MD, Franco Grego, MD  Journal of Vascular Surgery  Volume 42, Issue 2, Pages (August 2005) DOI: /j.jvs Copyright © 2005 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 A. Preoperative digital subtraction angiography demonstrates a collateral artery (arrow) originating from the aneurismal sack of the poplital aortic aneurysm. B, Digital subtraction angiography after coil-embolization of the collateral vessel and endograft deployment (arrows point to endograft location).

3 Fig 2 Intraoperative digital subtraction angiography shows the absence of endograft kinking during leg flexion (arrows point to endograft location). Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2005 The Society for Vascular Surgery Terms and Conditions

4 Fig 3 Kaplan-Meier analysis shows the primary patency rate for open repair (OR) (group A) and endovascular treatment (ET) (group B) at 6-month intervals. Standard error is >10% after 42 months for OR and after 24 months for ET (dashed line).

5 Fig 4 A. Angio-computed tomography scan and (B, C) plain radiograms of the knee 24 months after the procedure show the flexibility and the integrity of the Hemobahn stent graft during rest position and forced knee flexion (>120°).

6 Fig 5 Kaplan-Meier analysis of the secondary patency rate for open repair (OR) (group A) and endovascular treatment (ET) (group B) at 6 months intervals. Standard error is >10% after 42 months for OR (dashed line). Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2005 The Society for Vascular Surgery Terms and Conditions
