Primary anatomical suitability was evaluated according to the Investigational Device Exemption protocol for the Zenith p-branch endograft in a dedicated 3-dimensional vascular workstation. Secondary suitability was defined as any additional intervention needed to overcome adverse anatomical conditions at the access vessels. The Zenith p-branch endograft is available in 2 configurations (A and B), with the main difference being the distance between the superior mesenteric artery (SMA) and the renal fenestrations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The p-branch endograft showed a primary suitability of 54% (n=27). Each configuration was suitable in 18 (36%) patients. Main anatomical limitations were the clock position of the left renal artery (LRA; n=7, 14%), the distance between the SMA and LRA (A: n=16, 32%; B: n=16, 32%), and significantly narrowed or calcified iliac arteries. If additional interventions at the access vessels were employed, a secondary suitability of 64% (n=32) could be achieved.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>In this specific group of patients treated with chEVAR, the Zenith p-branch system would be suitable in about half of the patients, which could be raised to two-thirds with ancillary access vessel procedures.
