A comparison between standard and high density Resilient AneuRx in reducing aneurysm sac pressure in a chronic canine model Yuji Kanaoka, MD, Takao Ohki, MD, Joe Huang, MD, Amit Shah, MD Journal of Vascular Surgery Volume 49, Issue 4, Pages 1021-1028 (April 2009) DOI: 10.1016/j.jvs.2008.11.050 Copyright © 2009 Terms and Conditions

Fig 1 A, Wireless pressure sensor with basket wire. B, A polytetrafluoroethylene (PTFE) aneurysm and wireless sensor after removal of basket wire. Both ends of wireless sensor have three tiny holes. Using the stitches through the holes, wireless sensor was anchored inside the aneurysm sac.

Fig 2 Intraoperative view of aneurysm creation. Proximal aorta was taped with white vessel loop at the left side of image. Black arrows demonstrate stitches (6-0 prolene) to fix the wireless sensor. Trifurcation is beyond the distal aspect on the right side. Journal of Vascular Surgery 2009 49, 1021-1028DOI: (10.1016/j.jvs.2008.11.050) Copyright © 2009 Terms and Conditions

Fig 3 Intraoperative digital subtraction angiography of endovascular aneurysm repair (EVAR). A, Before EVAR, angiography demonstrates the prosthetic aneurysm with wireless sensor (arrows are the both ends of wireless sensor). B and C, After EVAR, angiography demonstrates successful exclusion from systemic circulation without endoleak. D, After EVAR, wireless sensor is easily recognized as two markers of both ends (arrows).

Fig 4 Intra-sac pressure following endovascular aneurysm repair (EVAR). A, intra-sac systolic pressure. Intra-sac systolic pressure remained at a high level in the standard AneuRx (STA) group whereas it gradually lowered in the Resilient AneuRx (RSA) group. This difference reached statistical significance at 2 months and lasted to 3 months. B, Intra-sac mean pressure had a similar trend to intra-sac systolic pressure. It gradually lowered in the RSA group. Intra-sac mean pressure was significant lower in RSA group than that in STA group at 3 months. C, Intra-sac pulse pressure. Intra-sac pulse pressure decreased immediately after EVAR. Intra-sac pulse pressure was significant smaller in the RSA group throughout the study. *significant difference between STA group and RSA group.

Fig 5 Digital subtraction angiography prior to euthanasia (3 months after endovascular aneurysm repair [EVAR]). A, Angiography demonstrates absence of endoleak. B, Magnified angiography shows that endograft is widely patent without stenosis. Journal of Vascular Surgery 2009 49, 1021-1028DOI: (10.1016/j.jvs.2008.11.050) Copyright © 2009 Terms and Conditions

Fig 6 Gross examination of explanted prosthetic aneurysm with endograft. A, Aneurysm treated with standard AneuRx (STA). B, aneurysm treated with resilient AneuRx (RSA). Proximal aorta is on the left side, distal on right side. Aneurysm was extirpated from suprarenal to below the trifurcation. Both aneurysm sacs were totally thrombosed without blood flow. Wireless sensors were attached inside the aneurysm sac (arrows). Journal of Vascular Surgery 2009 49, 1021-1028DOI: (10.1016/j.jvs.2008.11.050) Copyright © 2009 Terms and Conditions
