    Abstract A total femoral approach for fenestrated-branched endovascular aortic aneurysm repair has been increasingly favored to minimize risks of aortic arch manipulation. We describe a novel technique to support the advancement of endovascular devices into a target vessel. Following catheterization of the intended target artery and deployment of the diameter-reducing ties, a Coda semi-compliant balloon (Cook Medical) is advanced and inflated immediately above the target artery. It is used as a support as the wire, catheter, or sheath "bounces" on the balloon, stabilizing the support wire to advance stent grafts, balloons, or sheaths into the downward renal or mesenteric vessels.

    Abstract Fenestrated-branched endovascular aortic repair (FB-EVAR) has gained widespread acceptance in patients with complex aortic aneurysms. It has evolved from an alternative to treat elderly and higher risk patients to the first line of treatment in most patients with suitable anatomy, independent of the clinical risk. Currently, these devices are available off-the-shelf (ready to use) and tailored to the patient anatomy with the options of fenestrated, branched and mixed fenestrated, and branched designs. Reports from single and multicenter experiences and systematic reviews have shown lower mortality and morbidity for FB-EVAR compared with historical results of open surgical repair. The main advantages are noted on mortality, respiratory complications, acute kidney injury, and length of hospital stay. The purpose of this article is to review the advances in the endovascular repair of complex aortic aneurysms exploring the indications for treatment, preoperative evaluation, patient selection, device design, and implantation technique.

    Abstract Fenestrated-branched endovascular repair (FB-EVAR) has been widely applied to treat chronic post-dissection thoracoabdominal aortic aneurysms (TAAAs) with favorable outcomes. A recent multicenter experience indicates that outcomes of FB-EVAR for chronic post-dissection are comparable to degenerative TAAAs. Anatomical and technical pitfalls are different than degenerative aneurysms because of true lumen compression, separate target vessel origin from true or false lumen and possible extension of dissection flaps into the renal and mesenteric vessels. This article focuses on planning and sizing FB-EVAR in patients with chronic post-dissection TAAAs.

    Abstract Objective: To describe a single-center experience of "complete aortic repair" consisting of surgical or endovascular total arch replacement/repair (TAR) followed by thoracoabdominal fenestrated-branched endovascular aortic repair (FB-EVAR).
    Methods: We reviewed 480 consecutive patients who underwent FB-EVAR with physician-modified endografts (PMEGs) or manufactured stent-grafts between 2013 and 2022. From those, we selected only patients treated with open or endovascular arch repair and distal FB-EVAR for aneurysms involving the ascending, arch and thoracoabdominal aortic segments (zones 0-9). Manufactured devices were used under an investigational device exemption protocol. Endpoints included early/in-hospital mortality, mid-term survival, freedom from secondary intervention, and target artery instability.
    Results: There were 22 patients, 14 men and 8 women with a median age of 72±7 years. Thirteen postdissection and 9 degenerative aortic aneurysms were repaired with a mean maximum diameter of 67±11 mm. Time from index aortic procedure to aneurysm exclusion was 169 and 270 days in those undergoing 2- and 3-stage repair strategies, respectively. The ascending aorta and aortic arch were treated with 19 surgical and 3 endovascular TAR procedures. Three (16%) surgical arch procedures were performed elsewhere, and perioperative details were unavailable. Mean bypass, cross-clamp, and circulatory arrest times were 295±57, 216±63, and 46±11 minutes, respectively. There were 4 major adverse events (MAEs) in 2 patients: both required postoperative hemodialysis, 1 had postbypass cardiogenic shock necessitating extracorporeal membrane oxygenation, and the other required evacuation of an acute-on-chronic subdural hematoma. Thoracoabdominal aortic aneurysm repair was performed with 17 manufactured endografts and 5 PMEGs. There was no early mortality. Six (27%) patients experienced MAEs. There were 4 (18%) cases of spinal cord injury with 3 (75%) experiencing complete symptom resolution before discharge. Mean follow-up was 30±17 months in which there were 5 patient deaths-0 aortic related. Eight patients required ≥1 secondary intervention, and 6 target arteries demonstrated instability (3 IC, 1 IIIC endoleaks; 2 TA stenoses). Kaplan-Meier 3-year estimates of patient survival, freedom from secondary intervention, and target artery instability were 78±8%, 56±11%, and 68±11%, respectively.
    Conclusion: Complete aortic repair with staged surgical or endovascular TAR and distal FB-EVAR is safe and effective with satisfactory morbidity, mid-term survival, and target artery outcomes.
    Clinical impact: The presented study demonstrates that repair of the entirety of the aorta - via total endovascular or hybrid means- is safe and effective with low rates of spinal cord ischemia. Cardiovascular specialists within comprehensive aortic teams at should feel confident that staged repair of the most complex degenerative and post-dissection thoracoabdominal aortic aneurysms can be safely performed in their patients with complication profile similar to that of less extensive repairs. Meticulous and intentional case planning is imperative for immediate and long-term success.

    Abstract Purpose: To analyze the effectiveness of type II endoleaks (T2E) embolization using intra-operative contrast-enhanced ultrasound (CEUS).
    Methods: Consecutive patients treated for T2E underwent a standardized protocol with trans-arterial or trans-lumbar access, large volume embolization, onlay fusion, and intra-operative CEUS. Technical success was defined by exclusion of endoleak by CEUS.
    Results: Twenty-six patients (mean age 81 ± 11 years old; 89% male) were treated. The mean aneurysm sac enlargement was 11 ± 8 mm from T2E diagnosis. Embolization was performed using Onyx® 18 in all patients with adjunctive coils in 13 patients (50%). After the first embolization, CEUS documented residual T2E in 13 patients (50%). Ten patients (38%) had additional embolization, which successfully eradicated the T2E in seven of them. Technical success was 50% after the first embolization attempt and 77% after additional attempts guided by CEUS (P = 0.080). There was no mortality. Median imaging follow-up was 22 months. Among the 20 patients with no residual T2E on completion CEUS, 16 (80%) had sac stabilization and none required additional interventions for T2E. Of the six patients with residual T2Es on CEUS, three had sac stabilization (50%) and one required additional reintervention for T2E. There was one late aortic rupture at 56 months.
    Conclusion: One in two patients treated by T2E embolization had residual endoleak on intra-operative CEUS after a first embolization attempt, decreasing to one in four patients after multiple attempts. A negative completion CEUS following embolization was associated with higher rates of sac stabilization and no need for additional T2E embolization.
