The AFX2 Anatomically Fixated Endograft Has Related Outcomes to Commercially Accessible Proximally Fixated Endografts: 5-Yr Outcomes of the LEOPARD Trial
Introduced by Christopher J. Kwolek, MD, MBA
The LEOPARD ( EVAR Outcomes by Main Evaluation of Randomized Knowledge) trial is the primary potential randomized scientific trial designed to match related scientific outcomes after endovascular aneurysm restore utilizing modern commercially accessible units.
A complete of 455 sufferers have been randomized. 235 sufferers have been handled with a stent graft utilizing anatomic fixation and the AFX/AFX2 machine (Endologix) with Duraply, and 220 sufferers have been handled with a stent graft utilizing proximal fixation (91 Endurant [Medtronic], 72 Gore Excluder [Gore & Associates], and 57 Zenith [Cook Medical]). Demographic and anatomic traits have been comparable between the teams.
Sufferers have been adopted for five years, and an unbiased core lab was utilized. All device-related occasions and main adversarial occasions have been reviewed and adjudicated by an unbiased doctor.
At 5 years, there was no distinction between the anatomic and proximal fixation teams with respect to aneurysm-related mortality, aneurysm rupture, all-cause mortality, reintervention, or limb occlusion. Freedom from open conversion was statistically decrease for the AFX group at 5 years at 100% versus 98% for the proximal fixation group (P = .0142).
The first endpoint was aneurysm-related problems (ARCs) mixed with the next: periprocedural demise, aneurysm rupture, open conversion, any kind of endoleak (I, II, III, IV), limb occlusion, migration > 10 mm, sac enlargement > 5 mm, and device-related reintervention.
Freedom from ARCs was greater at 5 years for the AFX group at 63.8% versus 55.5% for the proximal fixation group and was predominantly pushed by the upper kind II endoleak fee famous within the proximal fixation group.
In abstract, all 4 units have been efficient for stopping aneurysm rupture and aneurysm-related demise in over 97% of sufferers out to five years. There was no distinction in kind I or kind III endoleaks famous, and reintervention was required in 15% of sufferers in each teams at 5 years with minimal want for open conversion. 70% of sufferers have been nonetheless alive at 5 years, and thus additional follow-up will likely be obligatory to find out long-term outcomes.
Utility of Sirolimus Drug-Eluting Balloons within the Remedy of Complicated Beneath-the-Knee Atherosclerotic Illness in Sufferers With Continual Limb-Threatening Ischemia—24‑Month Outcomes From the PRESTIGE Research
Introduced by Tjun Y. Tang, MD
The usage of sirolimus-eluting balloons (SEBs) to enhance long-term tibial artery patency in persistent limb-threatening ischemia (CLTI) is novel. The PRESTIGE research investigated efficiency outcomes and security of the Selution sustained limus launch (SLR) SEB (MedAlliance SA) for remedy of TASC II C and D tibial occlusive lesions in sufferers with CLTI from Singapore. We report 24-month outcomes.
PRESTIGE was a potential, nonrandomized, single-arm, multi-investigator, single-center scientific pilot research. 25 sufferers (25 limbs; 33 lesions) with Rutherford class 5 wound severity have been initially included, and 18/25 (72%) sufferers have been accessible for 24-month evaluation. Collected information included clinically pushed goal lesion revascularization (CD-TLR), amputation-free survival (AFS), change in Rutherford class, wound standing, EQ-5D quality-of-life survey, and Strolling Impairment Questionnaire (WIQ).
Baseline demographics included 17 (68.0%) males; imply age was 63.7 ± 9.7 years. Important comorbidities included diabetes mellitus (n = 22; 88.0%) and end-stage renal failure (n = 11; 44.0%). Fifteen (45.5%) sufferers had TASC II D lesions, and imply lesion size handled was 19 ± 11 cm. At 24 months, AFS was 75.0% (18/24 sufferers; 4 deaths and a pair of main decrease extremity amputations), and freedom from CD-TLR was 87.0%. Imply Rutherford class improved from 5.00 at baseline to 0.44 ± 1.33 (P
The Selution SLR SEB stays protected and efficacious in treating complicated tibial arterial occlusive lesions on this frail cohort of CLTI sufferers with a excessive prevalence of diabetes and end-stage renal failure. Nonetheless, medium-term outcomes reveal a pattern of illness development or recurrence as mirrored by worsening of the WIQ.

Introduced by Maureen P. Kohi, MD
Regardless of the excessive prevalence of peripheral artery illness (PAD) in girls and underrepresented minorities (URMs), these teams are occasionally included in PAD trials. The ELEGANCE registry is a worldwide, nonrandomized, open-label, potential, multicenter registry actively amassing real-world information on outcomes following endovascular remedy of PAD, with an emphasis on enrolling various sufferers handled with drug-eluting units (DEDs). Inclusion standards included age ≥ 18 years, written knowledgeable consent, and remedy with any commercially accessible Boston Scientific Company DEDs marketed for lesions in peripheral artery circulation. ELEGANCE goals to enroll at the very least 40% every of girls and URMs. Sufferers enrolled will likely be adopted as much as 5 years put up–index remedy.
As of July 28, 2022, 579 sufferers (710 lesions) have been enrolled throughout 46 activated websites in america, China, Germany, and Thailand. Imply age is 69.6 years (SD ± 9.7 years); 241 (41.6 %) are feminine and 235 (40.6%) are URMs. Of those, 117 (20.2%) are Black or of African heritage, 55 (9.5%) are Asian, and 47 (8.1%) are Hispanic/Latino. Comorbidities and danger components embrace present (156 [27.4%] sufferers) or previous smoking (292 [51.3%] sufferers); kind 2 diabetes mellitus (305 [52.7%] sufferers); and historical past of hyperlipidemia (468 [82.2%] sufferers) and/or historical past of hypertension (515 [90.5%] sufferers) requiring treatment. Remedy indications embrace claudication (370 [66.3%] sufferers) and persistent limb-threatening ischemia (143 [25.6%] sufferers). Median lesion size was 100 mm (IQR, 60-200 mm). Of 710 handled lesions, 513 (72.7%) have been de novo and 193 (27.3%) have been restenotic. Calcification was average or extreme in 178 (25.3%) and 225 (32.0%) sufferers, respectively. Among the many 538 sufferers with accessible Rutherford classification at baseline, 204 (37.9%) have been ≥ class 4.
By emphasizing variety of sufferers studied, ELEGANCE will enhance therapeutic decision-making and scientific outcomes for the administration of PAD with DEDs in all populations, together with these uncommonly included in PAD trials.
Revascularization Remedy for Femoropopliteal Illness With a Novel Intra-Arterial Stent Graft: 12-Month Outcomes of the TORUS-2 Research
Introduced by Ehrin J. Armstrong, MD
The Torus stent graft system (Endologix) represents the primary lined stent for the superficial femoral artery (SFA) launched in practically 20 years. The purpose of the TORUS 2 research is to research each the protection and effectiveness of this potential lined stent graft choice by evaluating outcomes to preestablished efficiency objectives.
The TORUS 2 research is a potential, single-arm, multicenter, worldwide trial. Comply with-up was scheduled at 30 days, 6 months, after which yearly via 12 months 3. The first effectiveness endpoint assesses major patency at 12 months, which is outlined as absence of clinically pushed goal lesion revascularization (CD-TLR) and recurrent goal lesion diameter stenosis > 50% with a peak systolic velocity ratio of > 2.5. The first security endpoint is a composite consequence of a number of main adversarial occasion (MAE) varieties via 30 days, consisting of all-cause mortality, CD-TLR, and amputation of the goal limb.
A complete of 188 sufferers have been enrolled and handled with the Torus stent graft system throughout 34 websites. The imply age is 69.7 ± 8.4 years, 72% are male, and 84% had a Rutherford class ≥ 3. The imply lesion size as assessed by the core lab is 118 ± 44 mm and ranges as much as 275 mm. 52% had average to extreme calcification. Imply most stenosis was 89%, starting from 50% to whole occlusion, and 36% of sufferers introduced with a complete occlusion of the diseased vessel. Technical success was achieved in 100% of sufferers. 13% of sufferers underwent atherectomy. The 30-day MAE fee (141 sufferers) was 1.4% (2 CD-TLRs have been reported at day 14 and 18). By means of 1 12 months, there have been 4 (2.8%) deaths, 24 (17.0%) CD-TLRs, and one (0.7%) goal limb amputation. At 1 12 months, the liberty from CD-TLR was 75.7%.
A Registry-Primarily based Research of Paclitaxel Drug-Coated Balloon Angioplasty for the Remedy of In-Stent Restenosis of the Femoral-Popliteal Artery
Introduced by Daniel J. Bertges, MD
The Society for Vascular Surgical procedure (SVS) Vascular High quality Initiative (VQI) carried out a potential, single-arm, registry-based research assessing the protection and efficiency of a paclitaxel drug-coated balloon (DCB) (In.Pact Admiral, Medtronic) for the remedy of superficial femoral artery (SFA) or popliteal artery in-stent restenosis (ISR). The research included 43 websites throughout america and evaluated 300 sufferers.
Scientific outcomes have been assessed at 12, 24, and 36 months. The first endpoint was goal lesion revascularization (TLR) at 12 months. Secondary endpoints included technical success, goal vessel revascularization (TVR), main limb amputation, and all-cause mortality.
Sufferers have been typical of the peripheral artery illness inhabitants with a imply age of 68 years, 58% male, and 56% with diabetes. The bulk had claudication (80% Rutherford class 2-3), whereas 20% had ischemic relaxation ache (Rutherford class 4). Lesions included ISR of the SFA in 68%, SFA-popliteal in 26%, and popliteal arteries in 7%. Imply lesion size was 17.8 ± 11.8 cm. Occlusions have been handled in 43% of lesions (imply occluded size, 16 ± 10 cm). Kind by TransAtlantic Inter-Society Consensus (TASC) included: TASC A, 17%, TASC B, 29%; TASC C, 38%; and TASC D, 15%.
Primarily based on interim Kaplan-Meier estimates at 12 and 24 months, freedom from any TLR was 90% and 72%, freedom from any TVR was 88% and 68%, freedom from main goal limb amputation was 99% and 99%, and all-cause survival was 95% and 89%.
This postmarket registry-based research of the In.Pact Admiral paclitaxel DCB reveals promising leads to treating femoropopliteal ISR with freedom from TLR of 90% at 1 12 months. These outcomes reveal the power of the SVS VQI to conduct postmarket analysis of peripheral units in partnership with business and federal regulators.
