Abstract
PURPOSE To describe the X-over reversed iliac extension technique in a patient with severe peripheral arterial disease (PAD) scheduled for inner branched endovascular aortic repair (iBEVAR). TECHNIQUE A multimorbid 62-year-old male patient was planned for iBEVAR due to a 58 mm suprarenal aortic aneurysm. The patient had a previous right femoropopliteal bypass and stenting of the left iliac axis. At admission, he presented with recent onset severe left limb claudication, which was attributed to left iliac stent occlusion. To avoid the postoperative compression of the right common femoral artery (CFA) and preserve the patency of the bypass, a single left CFA access, followed by left iliac artery recanalization, was decided. The right iliac axis was catheterized with a Lunderquist wire using X-over access from the left CFA. An iliac extension (ZISL, 24-59, Cook Medical, Bloomington, USA) was reversed and resheathed on back-table and implanted in the right common iliac artery using the X-over technique. The left CFA access was used to complete the remaining steps of the procedure. The predischarge computed tomography angiography confirmed bilateral iliac artery and femoropopliteal bypass patency. CONCLUSION The X-over reversed iliac extension technique may be applied in selected PAD patients, when undergoing complex endovascular aortic repair. CLINICAL IMPACT As the number of patients with peripheral arterial disease (PAD) is expected to increase the upcoming decades, out of the box solutions may be needed to assist complex endovascular aortic management. The X over technique, which consist of the contralateral advancement of an on-table reversed iliac limb, was successfully applied in a patient with severe PAD and numerous previous peripheral interventions, who was managed with branched endovascular aortic repair . The X Over technique may provide an additional alternative in well-selected patients with demanding vascular access undergoing complex endovascular aortic procedures.

Ann Vasc Surg 2024; 109:47-54. [PMID: 39029892 DOI: 10.1016/j.avsg.2024.06.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 06/07/2024] [Accepted: 06/16/2024] [Indexed: 07/21/2024]
Abstract
BACKGROUND Variations in sac shrinkage (SS) are noted between endovascular aneurysm repair for abdominal aortic aneurysm (AAA) and fenestrated endovascular aneurysm repair for short neck AAA. These variations may originate from difference in the geometry and length of proximal sealing, which influences the quality and durability of the seal. This study aimed to explore the disparities in aneurysm exclusion and sac remodeling across these 2 scenarios. METHODS This study involved a retrospective analysis of prospectively collected data from 2014 to 2021. Of 486 endovascular abdominal aortic repair cases, 33 that exclusively used a low permeability expanded polytetrafluoroethylene infrarenal device, strictly adhering to the instructions for use (IFUs), were selected. Concurrently, 30 cases of fenestrated repair that utilized modified polyester woven fabric devices proximally with consistent use of the aforementioned low-permeability devices infrarenally were examined. The quality of both proximal and distal sealing zones in fenestrated repairs was maintained within the range specified in the expanded polytetrafluoroethylene infrarenal device's IFUs, ensuring consistent sealing integrity for reliable group comparisons. Key metrics used for analysis were the detection of endoleaks and measurements of sac dimensions. Additional analyses included comparisons of demographic data and postoperative diameter changes in the proximal sealing zone (PZ) (encompassing 0, 5, 10, 15, and 20 mm below the most proximal sealing stent). RESULTS The demographic data and preoperative maximum-minimum diameter of the aneurysms did not differ between the groups. Proximal neck dilatation was similarly observed after both procedures. Immediately after the procedure, the incidence of lumbar arterial type II endoleaks was significantly lower after fenestrated repair than that after endovascular aortic repair (EVAR, 10% vs. 39.4%, P = 0.0094). At the final observation, EVAR substantially reduced the PZ length (-4.73 ± 15.30%), while fenestrated repair maintained the length (21.98 ± 24.34%; P < 0.0001). The preservation of the sealing length in fenestrated repairs was attributable to dilation occurring within the sealing range of the proximal device, oversized to accommodate the larger diameters in the more proximal sections of the aorta. The cumulative occurrence of SS (>5 mm) following fenestrated repair increased faster than that after endovascular repair (P = 0.002). CONCLUSIONS Although aortic neck dilatation progressed similarly in both groups, fenestrated repair maintained the sealing length and demonstrated a greater extent of SS, even under the challenging circumstances in PZ. The superior postoperative results were linked to both the durability of proximal sealing and a lower occurrence of lumbar arterial type II endoleaks, stemming from the effective shuttering of the collateral sources in the proximal lumbar or intercostal arteries.

Abstract
PURPOSE To analyze the early performance and efficacy of the first commercially available off-the-shelf precannulated multibranched endograft in the endovascular repair of pararenal abdominal aortic aneurysms (PAAAs). The device received European marketing approval in late 2020. MATERIALS AND METHODS Between January 2021 and June 2023, a retrospective analysis of prospectively collected data from all consecutive patients with pAAAs undergoing implantation of the E-nside precannulated inner-branched endograft was conducted in 2 centers. The primary outcome measure was technical success defined as the composite endpoint of successful (1) delivery of the 24F endograft, (2) use of the precannulation tubes, and (3) implantation of the bridging stent-grafts (BSGs) to the target vessels. Main secondary endpoints were mortality, target vessel instability (TVI), absence of type I or III endoleak, reintervention, spinal cord ischemia, and supra-celiac aortic coverage. RESULTS Twenty-one patients (20 men, mean age: 71 years) were included in this study with a mean follow-up of 14±7.7 months. Nine patients had a symptomatic aneurysm (43%). Technical success amounted to 95% (in one patient, an iliofemoral conduit was necessary to advance the device). One out of 112 BSGs (1%, right renal artery) occluded at 30 days, resulting in freedom from TVI and reintervention rate at 12 months of 95%. No type I or III endoleaks were identified during follow-up. One patient (5%) died at 13 months due to non-aneurysm-related death, and 1 patient (5%) developed spinal cord ischemia. No other major perioperative complications were observed. Mean supra-celiac aortic coverage reached 52±8%. CONCLUSIONS Given the imperative need for an off-the-shelf endograft tailored to address PAAAs, the E-nside stent-graft demonstrated encouraging outcomes in this study. Nevertheless, it is essential to emphasize that the extent of aortic coverage mandates the production of a truncated variant. CLINICAL IMPACT The endovascular repair of urgent pararenal aortic aneurysms remains still an unsolved problem in the endovascular era since there are no available off-the-shelf dedicated fenestrated or branched endografts. This paper confirms the safety and efficacy of the off-the-shelf precannulated inner branched endograft for this specific indication.

Abstract
Introduction Endovascular repair using off-the-shelf endografts is a viable solution in patients with ruptured or symptomatic complex aortic aneurysms. This analysis aimed to present the peri-operative and follow-up outcomes in urgent and emergent cases managed with the t-Branch multibranched thoracoabdominal endograft. Methods Prospectively collected data from all consecutive urgent and emergent cases managed in two aortic centers between January 1st, 2014, to November 30th, 2022, using the t-Branch device (Cook Medical Inc., Bjaeverskov, Denmark) were analyzed. Patients presenting with ruptured aortic complex aneurysms were characterized as emergent and patients with aneurysms >90 mm of diameter, or symptomatic aneurysms were characterized as urgent. Technical success, 30-day mortality, major adverse events (MAE) and spinal cord ischemia (SCI) rates were assessed. Results 225 patients (36.5% females, 72.5 ± 2.8 years) were included; 73.0% were urgent. The mean aneurysm diameter was 109 ± 3.9 mm and 44.4% were type I-III TAAAs. Females (p = .03), para-renal aneurysms (p = .02) and ASA score IV (p < .001) were more common in emergent cases. Technical success was 97.8%. Thirty-day mortality and MAE rates were 17.8% and 30.6%, respectively. SCI rate was 14.7%, (4.8% paraplegia rate) with 22.2% of patients receiving prophylactic cerebrospinal drainage. Thirty-day mortality (13.3% vs. 26.7%, p = .04) and MAE (26.0% vs. 43.0%, p = .02) were more common among emergent cases while technical success (97.6% vs. 98.3%, p = .9), and SCI (13.3% vs. 18.3%, p = .4) were similar. Survival at 12-months was 83.5% (SE 5.9%) for the urgent and 77.1% (SE 8.2%) for the emergent group (log rank, p = 0.96). Conclusion T-Branch represents an effective and safe solution for the management of urgent and emergent cases with complex aortic aneurysms, with high technical success, promising early mortality and SCI rates.

Initial Experience with Fenestrated Physician-Modified Stent Grafts Using 3D Aortic Templates. J Clin Med 2022; 11:jcm11082180. [PMID: 35456273 PMCID: PMC9027705 DOI: 10.3390/jcm11082180] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Revised: 04/07/2022] [Accepted: 04/11/2022] [Indexed: 12/04/2022] Open
Abstract
The goal of this study was to describe the surgical results of physician-modified endografts (PMEG) utilizing a 3D aortic template in a center with no prior experience in complex endovascular aortic repairs. Forty-three patients underwent physician-modified graft stent implantation using a 3D aortic model. The inclusion criteria were juxtarenal and suprarenal aortic aneurysms, type IV thoracoabdominal aneurysms, and type IA endoleak after endovascular aortic repair. In asymptomatic patients, the diameter threshold for aneurysm repair was 5.5 cm in males and 5.0 cm in females. 3D aortic templates were prepared from the patient’s computed tomography angiography scans and sterilized before use in the operating suite. Forty-three stent grafts were modified with the use of a 3D printing template. A total of 162 reinforced fenestrations (37 celiac, 43 right renal, 39 left renal, 43 superior mesenteric) with a mean of 3.8 per patient were performed. All PMEGs had a posterior reducing-diameter tie and a preloaded guidewire. The mean modification time was 86 ± 12 min. The mean follow-up was 14 ± 12 months. The 30-day mortality was 12%. During the follow-up period, the patency rate was 95% per the superior mesenteric artery, 93% per right renal artery, 95% per left renal artery, and 89% per celiac trunk. Twelve (28%) patients had endoleak, of which type I or III was present in 5 (12%) patients, and type II in 7 (16%). 3D printing can be successfully integrated into the physician’s everyday practice of stent graft modification. However, the use of this approach in centers without experience performing complex aortic procedures results in worse surgical metrics than those previously reported.
