Purpose: To present a cardiac asystole technique that assists in the accurate deployment of stent-grafts during endovascular repair of thoracic or abdominal aortic aneurysms. Technique: In the anesthetized patient, trial doses of intravenous adenosine are delivered until a ≥ 20-second period of asystole is recorded. The endograft procedure then proceeds until the device is ready for deployment. The predetermined dose of adenosine is administered, and the device is deployed during asystole. Adenosine-induced transient asystole has been utilized in 16 patients undergoing balloon-expandable endograft exclusion of 6 thoracic aortic and 10 abdominal aortic aneurysms. Asystole lasted for 20 to 30 seconds, during which time the devices were accurately deployed without interference from the aortic flow. There were no clinical sequelae of this technique in any patient. Conclusions: Pharmacologically induced transient asystole appears to be a safe maneuver to preclude endograft movement by systolic blood flow. The technique permits precise placement of balloon-expandable stent-grafts and is applicable to self-expanding devices as well. Interventionists may wish to incorporate adenosine-induced asystole into their aortic aneurysm exclusion procedures.

Purpose: To evaluate the potential anatomical feasibility of using the off-the-shelf multibranched Zenith t-Branch for the treatment of thoracoabdominal aortic aneurysms (TAAAs) in female patients. Materials and Methods: A total of 268 patients (median age 68 years; 69 women) with degenerative TAAA treated at a single institution by means of open or endovascular repair between 2007 and 2019 were retrospectively analyzed to determine the feasibility of using the Zenith t-Branch based on the manufacturer’s instructions for use. The factors determining overall anatomical feasibility were divided into vascular access, aortic anatomy, and visceral vessels. The results were stratified by sex and compared. A logistic regression model was constructed to determine any association between feasibility and clinical factors or potential confounding variables; results are expressed as the odds ratio (OR) with 95% confidence interval (CI). Results: The overall anatomical feasibility was 39% (22% women vs 45% men, p=0.001). The feasibility was negatively influenced by female sex (p<0.001) in multivariable analysis (OR 2.9, 95% CI 1.5 to 5.4, p=0.001). Vascular access feasibility was 82% (61% women vs 89% men, p<0.001). Aorta feasibility was 65% (52% women vs 69% men, p<0.001), and visceral vessel feasibility was 74% (78% women vs 73% men, p=0.260). An access diameter ≤8.5 mm excluded 17% of the patients (39% women vs 9% men, p<0.001). The aortic feasibility was limited by the infrarenal aortic diameter in 16% of patients (45% women vs 6% men, p<0.001) and the aortic lumen at the visceral vessels in 17% patients (19% women vs 17% men, p=0.741). The visceral vessel feasibility was mainly limited by inadequate numbers or diameters of target vessels. Location and orientation of the target vessels were adequate in 96% of patients. Conclusion: A little more than a third of an all-comers cohort of patients with degenerative TAAA could have been treated with on-label use of the Zenith t-Branch. However, only 22% of women could have been treated because of sex-related anatomical limitations. New generations of multibranched devices should address these differences.
