Abstract
OBJECTIVE This study aimed to report the long-term outcomes beyond 10 years of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms using the low-profile INCRAFT device. METHODS This was a single-center, retrospective cohort study of all patients undergoing EVAR using the INCRAFT device as part of the regulatory trial between 2012 and 2013. Primary endpoint was aneurysm-related death. Secondary endpoints were all-cause death, reintervention, late open conversion, and aneurysm status (shrinkage, stable, and growth). RESULTS Thirty patients with a mean age of 71.8 ± 7.7 years were included in this study. The median aneurysm diameter at EVAR was 54.5 mm (interquartile range, 53-56.8 mm). All abdominal aortic aneurysms in this study were treated following the device's instructions for use. At index EVAR, the INCRAFT device was successfully implanted in all patients using a percutaneous approach under local anesthesia. No patients experienced major adverse events or procedure-related complications 30 days after EVAR. During the median follow-up of 125 months (interquartile range, 98-131 months) with follow-up rates of 100% at 5 years and 96.7% at 10 years, aneurysm-related mortality was 0%, and freedom from all-cause mortality was 82.9% at 5 years and 75.3% at 10 years. Reintervention was required in 10 patients with 15 procedures. Sac growth was observed in 11 patients (36.7%), six of whom eventually required late open conversion; five of these patients underwent open aneurysmorrhaphy with stent graft preservation, and one underwent open surgical repair with endograft explantation. Late rupture was identified in one case, where type Ia endoleak led to rupture at 69 months, and open repair was successfully performed. Freedom from reintervention was 89.0% at 5 years but declined to 60.9% at 10 years; freedom from late open conversion was 100% at 5 years but declined to 70.8% at 10 years. CONCLUSIONS Long-term outcomes of the INCRAFT stent graft showed no aneurysm-related deaths. However, sac growth occurred persistently throughout the follow-up period, resulting in a relatively high rate of reinterventions in the later periods, which highlights the importance of lifelong postoperative surveillance and appropriate reinterventions when indicated.

Reintervention Rate after Treatment with the INCRAFT AAA Ultra-Low-Profile Stent Graft System. Ann Vasc Surg 2024; 109:216-224. [PMID: 39019258 DOI: 10.1016/j.avsg.2024.05.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 05/09/2024] [Accepted: 05/12/2024] [Indexed: 07/19/2024]
Abstract
BACKGROUND The INCRAFT stent graft system is an ultra-low-profile endograft for the exclusion of infrarenal aortic aneurysms. In the market approval studies, an increased rate of device-related complications was observed and the endograft was approved with mandated postmarketing investigations. Our aim was to analyze mid-term outcomes of a real-world patient cohort treated with the INCRAFT endograft. METHODS Consecutive patients treated with the INCRAFT endograft between February 2015 and December 2022 at a single institution were included. In accordance with the Society for Vascular Surgery reporting standards, safety endpoints were reported and outcome endpoints included reinterventions, technical success, aortic-related and overall-mortality, endoleak, stent fracture, and endograft migration >5 mm. RESULTS Eighty patients (85% male) with a mean age of 76 ± 7 years were included. Fifty-two patients (65%) were treated within the endograft's instruction for use. Mean aortic diameter was 59 ± 10 mm and 91% of the procedures were performed percutaneously. Mean follow-up (FU) was 37 ± 25 months and there was no aortic- or procedure-related mortality. Reinterventions occurred in 25 patients (31%) with a freedom from reintervention at 1, 3, and 5 years of 84%, 66%, and 55%. The most frequent reinterventions were limb graft stenting (23%) and type II endoleak embolization (14%). Limb occlusion rate was 9% and in 3 patients (4%) distal endograft migrations >5 mm occurred. Persisting type II endoleaks were observed in 29% and aneurysm diameter was stable in 41% and had shrunk in 38%. Three type III endoleaks (4%) developed during FU and 4 open conversions (5%) were necessary. No known risk factors, including treatment outside instruction for use, were predictive for reinterventions. CONCLUSIONS Treatment of infrarenal aortic aneurysms with the INCRAFT stent graft system was safe and successful. Nevertheless, a substantial rate of reinterventions was necessary during FU to maintain endograft patency and prevent aneurysm growth.

Abstract
INTRODUCTION Favorable midterm outcomes have been reported with the use of low-profile endografts (LPE), but long-term data is still needed. Furthermore, it is unclear if each of these LPE may have advantages over the other, which may, in turn, affect the outcomes. We systematically reviewed the literature about complications and reintervention rates of patients submitted to endovascular aneurysm repair (EVAR) of abdominal aortic aneurysm (AAA) using LPE. MATHERIALS AND METHODS A literature search was conducted including articles that reported 30-days and follow-up mortality, complications, and reintervention rates of patients treated with EVAR using Incraft (Cordis), Zenith LP/Alpha (Cook Medical Inc) and Ovation (Endologix) endografts. RESULTS 36 papers were evaluated, reporting results of 582 patients treated with Zenith device, 1211 with Incraft and 3449 with Ovation. During follow up, similar survival and freedom from reintervention rates were reported among the various types of endograft both at 1 and 3 years. The incidence of limb stenosis/kinking was significantly higher in patients treated with Zenith LP/Alpha (2.1%, P = 0.008), while the Incraft device had a significantly lower proportion of type III endoleaks (P < 0.001). CONCLUSIONS Long-term survival and freedom from reintervention rates were comparable among the three LPEs. The Cook Zenith device had the highest rates of limb stenosis/kinking, while the Incraft device had the lowest occurrence of type III endoleak. PROSPERO Registration number: CRD42022315875.

Abstract
OBJECTIVE We evaluated the early and midterm outcomes of the Incraft (Cordis Corp, Bridgewater, NJ) ultra-low-profile endograft by analyzing data from the Triveneto Incraft Registry (TIR). METHODS TIR is an independent multicenter cohort registry of 10 vascular surgery units in the Triveneto area (Northeast Italy). A prospective analysis of patients electively treated with Incraft from September 2014 to June 2019 was performed. The main outcomes were technical success, major 30-day complications, 30-day aneurysm-related death, freedom from reintervention, and mortality rate during follow-up and were analyzed using Kaplan-Meier curves. Univariable Cox regression was used to evaluate the associations between anatomic complexity factors and reintervention. RESULTS During the study period, 209 patients were included in the registry. Their mean age was 76.9 ± 7.7 years and the Society for Vascular Surgery comorbidity score was 0.97 ± 0.52. Most patients (n = 181; 86.6%) had presented with at least one complex anatomic factor: aortic neck angle α <135° in 31 patients (14.8%), conic neck in 17 patients (8.2%), iliac tortuosity index τ >1.5 in 102 (48.8%), iliac artery calcification >50% in 106 (50.7%), and external iliac artery <6 mm in 45 (21.5%). The concurrent presence of two or more complex iliac anatomic factors was present in 67 patients (32.1%). The technical success rate was 99.5%, and the early major complication rate was 1.5% (one limb occlusion, one iliac branch stenosis, one type III endoleak [EL]). No 30-day mortality was recorded. The mean follow-up period was 18.5 ± 13.2 months. The overall mortality was 9.5% (n = 18), none related to the aneurysm. The freedom from reintervention rate was 92.1%. Of these patients, six (3.2%) had been treated for type II EL embolization, one (0.5%) for type IA EL, four (2.1%) for iliac branch occlusion, and one (0.5%) for flow-limiting external iliac artery dissection. None of the single anatomic factors analyzed were predictive of reintervention. However, the association of two or more complex iliac anatomic factors was predictive of related reintervention (hazard ratio, 7.25; P = .014). The crude reintervention rate in this complex subgroup of patients was low (4 of 67; 6%). CONCLUSIONS Data from the TIR have demonstrated excellent early and midterm outcomes of endovascular aneurysm repair using the Incraft stent graft in patients with complex anatomy. The concurrent presence of two or more complex iliac anatomic factors still represent an issue for endovascular aneurysm repair success. However, the technical characteristics of this device resulted in low intervention rates, even for patients with these challenging issues.

Ann Vasc Surg 2020; 72:464-478. [PMID: 32946999 DOI: 10.1016/j.avsg.2020.09.018] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 09/05/2020] [Accepted: 09/08/2020] [Indexed: 12/20/2022]
Abstract
OBJECTIVES Durability after endovascular aortic aneurysm repair (EVAR) is considered an ongoing topic of investigation and was always a point of concern with smaller profile devices. Recently released five-year clinical trial results using the Incraft® ultralow profile device are encouraging. However, additional real-life experience will need to assist these initial findings. Herein, we investigated the outcomes after EVAR, in real world practice using the Incraft® endograft (EG). MATERIAL AND METHODS Seventy-seven patients with infrarenal abdominal aortic aneurysms (AAA) ≥50 mm in diameter treated with the Incraft® device in three vascular centers were enrolled from November 2015 to July 2018. Follow-up was completed in August 2020. Selection of EVAR using the Incraft® device was individualized according to aorto-iliac morphologic features, comorbidities, history of previous abdominal surgery and preference of the patient. At the early phase of the study, we specifically opted for preferential use of this low profile EG mainly in cases of small and tortuous iliac vessels (more challenging access routes). At later stages, it was used according to surgeon preference and not specifically in complex anatomies (real-world conditions). End-points included technical success, perioperative complications, 30-day survival, endoleg patency, presence of endoleaks, sac enlargement >5 mm and clinical success. RESULTS The primary technical success rate was 97.4% before the addition of an aortic cuff and iliac extension for a type Ia and type Ib endoleak respectively, and the repair of a maldeployment iliac component (primary-assisted and secondary technical success, 100%). Intraoperative small type II endoleaks (visible in final angiogram) were noted in 19 patients (24.7%). There were no intraoperative deaths from AAA rupture, primary conversions or conversions to aortounilateral grafts. Two complications occurred, necessitating hybrid techniques for repair (replaced of a dislodged endoleg and distal external iliac artery hemostasis). No deaths were reported within 30 days. Occlusion of an endoleg, was observed in two patients, 6 and 14 months respectively after implantation (2.6%), and were treated by femoral-femoral PTFE bypass after unsuccessful endovascular recanalization. The latter required open conversion, 3 mo later, to repair compromised flow to the inflow iliac axis. Three patients (3.9%) experienced sac enlargement >5 mm in diameter compared with the 1-month CT scan. All of these had type II endoleaks and two received embolization procedures. Eleven patients died from causes unrelated to AAA repair. Clinical success was 97.3%, 92.8% and 89.4% through 1, 2 and 3 years respectively. CONCLUSIONS EVAR with the Incraft® device might be considered a reliable option in real-world conditions and not specifically only in complex iliac anatomies.

Abstract
OBJECTIVE We present the 5-year results of a prospective regulatory study of the INCRAFT device, a low-profile endovascular stent graft system for repair of abdominal aortic aneurysms. METHODS This was an open-label prospective nonrandomized single-arm study enrolling in centers in the United States and Japan. The primary effectiveness outcome was successful aneurysm treatment and the primary safety outcome was the incidence of major adverse events at 30 days after the procedure. Major long-term outcomes were mortality, reintervention, adverse limb outcomes, and suprarenal stent fracture. RESULTS One hundred and ninety patients (mean age, 73.8 ± 7.6 years; 90% male; 69% white and 30% Asian) were enrolled from 32 centers throughout the United States and Japan. Minimal access vessel size was less than 7 mm on both sides in 43.9% of the study cohort. Thirty-day major adverse events occurred in 3.2% of patients (6/190). Periprocedural technical success was 94.1% (176/187). Successful aneurysm treatment was 100% at 30 days and 87.9% at 1 year. Two patients required open conversion for thromboembolic complications, 3 developed new type I or III endoleaks, and 7 experienced graft or limb occlusion. Freedom from graft occlusion was 96 ± 2% at 1 year and 94 ± 2% at 5 years. Freedom from stent fracture was 97 ± 1% at 1 year and 87 ± 3% at 5 years. Freedom from aneurysm-related mortality was 99 ± 1% at 1 and 5 years. CONCLUSIONS This study demonstrates good efficacy and safety and a very low rate of aneurysm related deaths with the INCRAFT device in a population with a high proportion of challenging anatomy.

Abstract
Objective Gender-related differences in outcomes in complex endovascular aortic repair have not been profoundly investigated. Use of low profile abdominal devices as in chimney endovascular repair may be beneficial for female patients with pararenal pathologies. With the chimney technique, there is no need for large introduction sheaths. This could be an advantage in case of smaller in diameter iliac access especially in combination with stenosis or elongation. Aim of the present study was to compare the perioperative and mid-term outcomes between males and females patients treated with the chimney/snorkel technique for pararenal aortic pathologies. Methods The PERICLES registry collected the world wide experience with the chimney technique. According to the gender, patients were classified in two cohorts. Primary endpoints were freedom from occlusion of the chimney grafts and reintervention. Secondary endpoints included access site complications and need for surgical or interventional revision, Endoleak Type I rate, 30-day overall complications and mortality. Univariate comparison P-values were generated using either the likelihood ratio χ2 test, the Fisher exact test, the Wilcoxon rank sum test, or the log rank test. Kaplan–Meier curves estimated the outcomes in the long run. Results A total of 412 patients underwent Ch-EVAR, 71 (17%) females and 341 (83%) males with a mean age for both groups being 74 years were included in the present study. After 36 months of mean follow-up, no statistically significant difference was observed between the two cohorts regarding re-interventions ( P= .44). Freedom from occlusion rates at 36 months did not differed between the two groups (females 84% vs. 80% for males ( P= .033). For patients receiving more than one chimney stent, the odds of having a complication did not differ between males and females (M:F OR = 2.0, 95% CI: 0.6–6.4, P = 0.228); 30-day mortality was 0% in the female group, instead five male patients died within one month. ( P = 0.59). The incidence of acute renal failure was low in both groups without statistical difference: 2 (3.1%) vs. 13 (4.6%) 58 ( P = 1.00). Neither patient received an endoconduit to insert the abdominal device. Conclusions No statistically significant difference regarding the freedom from reintervention and chimney graft patency was observed between the two genders. The results highlight the beneficial use of the chimney technique in female patients who can have potentially higher risk of access complications.

Abstract
PURPOSE We aimed to report a preliminary single-center experience of elective endovascular aortic repair (EVAR) using ultra-low profile (ULP) endografts of 14 F outer diameter. METHODS Data of 67 consecutive patients who underwent EVAR using either Ovation (group A, n=30) or Incraft (group B, n=37) endografts were retrospectively analyzed. RESULTS Aorto-iliac anatomy was significantly different between the two groups, as patients of group A had a greater thrombotic apposition on proximal aortic neck (thrombus thickness: 7.2±1 mm vs. 3.3±1.6 mm, P = 0.042; percentage of the circumference covered by thrombus: 45.2%±10.4% vs. 18.7%±10.6%, P = 0.0003), while patients of group B had a more angulated proximal neck in the coronal axis (35.9°±6.4° vs. 16.7°±5°, P = 0.012). Procedural success was 93.3% and 97.3%, respectively, in groups A and B. One patient in group A required an immediate conversion to open surgery for persistent occlusion of both iliac limbs. Another patient required implantation of a conical endograft with a femoro-femoral right-to-left bypass for occlusion of the contralateral gate during the cannulation. In group B, one intraoperative type Ia endoleak was immediately corrected. Neither deaths nor major adverse events were recorded within 30-days. During a median follow-up of 15.2 months (range, 1-56.7 months) two type Ia endoleaks in group A required open conversion after 12.1 and 40.5 months, respectively. Three patients in group B required a reintervention after 30 days. Neither deaths nor aortic ruptures were recorded during follow-up. CONCLUSION Both ULP endografts showed satisfying early and mid-term results.

Abstract
Purpose: To report the initial clinical results of endovascular aneurysm repair (EVAR) using the low-profile (14-F) Altura Endograft System, which features a double “D-shaped” stent design with suprarenal fixation and modular iliac components that are deployed from distal to proximal. Methods: From 2011 to 2015, 90 patients (mean age 72.8±8.3 years; 79 men) with abdominal aortic aneurysm (AAA; mean diameter 53.8±5.7 mm) were treated at 10 clinical sites in 2 prospective, controlled clinical studies using the Altura endograft. Outcomes evaluated included mortality, major adverse events (MAEs: all-cause death, stroke, paraplegia, myocardial infarction, respiratory failure, bowel ischemia, and blood loss ≥1000 mL), and clinical success (freedom from procedure-related death, type I/III endoleak, migration, thrombosis, and reintervention). Results: Endografts were successfully implanted in 89 (99%) patients; the single failure was due to delivery system malfunction before insertion in the early-generation device. One (1%) patient died and 4 patients underwent reinterventions (1 type I endoleak, 2 iliac limb stenoses, and 1 endograft occlusion) within the first 30 days. During a median follow-up of 12.5 months (range 11.5–50.9), there were no aneurysm ruptures, surgical conversions, or AAA-related deaths. The cumulative MAE rates were 3% (3/89) at 6 months and 7% (6/89) at 1 year. Two patients underwent coil embolization of type II endoleaks at 6.5 months and 2.2 years, respectively. Clinical success was 94% (84/89) at 30 days, 98% (85/87) at 6 months, and 99% (82/83) at 1 year. Conclusion: Early results suggest that properly selected AAA patients can be safely treated using the Altura Endograft System with favorable midterm outcome. Thus, further clinical investigation is warranted to evaluate the role of this device in the treatment of AAA.

Abstract
OBJECTIVE The objective of this study was to report the 1-year follow-up study results of the new Horizon stent graft (Endospan, Herzliya, Israel) from two different prospective consecutive trials. The Horizon abdominal aortic aneurysm stent graft system is a 14F profile system requiring only a single access site. It consists of three modules, introduced separately: base limb (iliac to iliac limb); distal aortic limb; and proximal aortic limb with a bare suprarenal crown and active fixation. METHODS Data from the first in man (FIM) clinical study with 10 patients enrolled and the pivotal study with 30 patients were analyzed. Outcomes measured were freedom from major adverse events (MAEs) including all-cause mortality, myocardial infarction, renal failure, respiratory failure, paraplegia, stroke, bowel ischemia, and procedural blood loss ≥1000 mL. Performance end points included successful delivery and deployment of the device, freedom from aneurysm growth ≥5 mm, type I or type III endoleak, stent graft occlusion, conversion to open surgery, rupture, and stent graft migration. RESULTS In the FIM study, one conversion to open surgery with >1000 mL of blood loss was registered perioperatively. In the pivotal study, no perioperative MAE was registered. Overall, at 1-year follow-up, two deaths and one aneurysm growth unrelated to endoleak were registered. CONCLUSIONS The results of both the FIM and pivotal studies demonstrated that 39 of 40 procedures were successful for delivery and deployment of the Horizon stent graft. No MAE was registered during the follow-up. The primary safety and performance end points were met in both studies.

Abstract
PURPOSE To assess safety and short-term efficacy of endovascular repair of the thoracic aorta with the new Zenith Alpha stent-graft. METHODS Between August 2010 and May 2014, 33 patients (21 men; mean age 73.2±9.0 years) were treated Zenith Alpha stent-graft (group ZA). Outcomes of this group were compared with those of 34 patients (25 men; mean age 70.3±8.5 years) treated contemporaneously with the Zenith TX-2 for the same pathologies (group TX). The primary outcome measure was technical success. Data on iliac tortuosity, minimum access vessel diameter, and previous unsuccessful treatment with other endografts was also recorded. RESULTS Technical success was 93.9% in group ZA and 91.2% in group TX (p=0.67). There was no case of surgical death or conversion to open repair in either group. Two (6%) type I endoleaks occurred in group ZA and 3 (9%) in group TX (p=0.67). Three patients died within 30 days in group ZA vs. none in group TX (p=0.07). Mean minimum access vessel diameter was significantly smaller (5.07 vs. 6.65 mm, p=0.002) and iliac tortuosity indices significantly higher in group ZA (1.34 vs. 1.25, p=0.02). Access vessel complications occurred in 1 (3%) patient in group ZA and 4 (12%) patients in group TX (p=0.17). Significantly more patients in group ZA (6, 18%) were unsuccessfully treated previously with other endografts vs. none in group TX (p=0.01). CONCLUSION The new Zenith Alpha appears to be equally as safe and efficacious as the Zenith TX-2 while being used in patients with demanding access vessel morphology.

Abstract
BACKGROUND Low-profile (LP) stent grafts are now commercially available in Europe for endovascular aortic aneurysm repair (EVAR). In this study the midterm outcomes and characteristics of patients treated with this last generation of stent grafts were compared with a cohort of patients treated with "standard-profile" (SP) stent grafts. METHODS The current study enrolled all patients treated for elective EVAR by the SP Zenith Flex stent graft (Cook Medical, Bloomington, Ind) between March 2010 and November 2011 and patients treated for elective EVAR by the Zenith LP stent graft (Cook Medical) between November 2011 and March 2013. All patients had a follow-up >18 months. Preoperative computed tomography angiograms were analyzed on a dedicated three-dimensional workstation. All data were prospectively collected in an electronic database and retrospectively analyzed. A comparative study was conducted. RESULTS The present study included 208 patients (107 SP and 101 LP). Patients' physiologic characteristics were similar in both groups. The iliac anatomy was considered "more challenging" in LP patients: respectively, 7% and 22% (P = .002) of SP and LP patients had bilateral external iliac diameter <7 mm; and 16% and 34% (P = .005) had a combination of an external iliac diameter <7 mm and an iliac tortuosity ratio index >1.5. No 30-day deaths were documented. The 24-month freedom from reintervention and overall survival rates after SP and LP were, respectively, 88% and 91% (P = .450) and 92% and 96% (P = .153). The 24-month rates for freedom from sac expansion and from limb occlusion were 96.4% and 98.7% (P = .320) and 92% and 95% (P = .293), respectively. One patient in each group presented with a type I endoleak during follow-up, and two LP patients presented with a type III endoleak (P = .235). CONCLUSIONS This study demonstrates that the last-generation LP stent grafts have favorable midterm outcomes similar to SP stent grafts despite being used to treat more patients with unfavorable iliac anatomy.
