Objective: To report the cost of target lesion revascularisation procedures (TLR) for femoropopliteal peripheral artery disease (PAD) following stenting, from a healthcare payer's perspective., Methods: European multicentre study involving consecutive patients requiring femoropopliteal TLR (January 2017 - December 2021). The primary outcome was overall cost (euros) associated with a TLR procedure from presentation to discharge. Exact costs per constituent, clinical characteristics, and early outcomes were reported., Results: This study included 482 TLR procedures (retrospectively, 13 hospitals, six countries): 56% were female, mean age was 75 ± 2 years, 61% were Rutherford class 5 or 6, 67% had Tosaka class 3 disease, and 16% had common femoral or iliac involvement. A total of 52% were hybrid procedures and 6% involved open surgery only. Technical success was 70%, 30 day mortality rate was 1%, and the 30 day major amputation rate was 4%. Most costs were for operating time during the TLR (healthcare professionals' salaries, indirect and estate costs), with a mean of: €21 917 ± €2 110 for all procedures; €23 337 ± €8 920 for open procedures; €12 903 ± €3 108 for endovascular procedures; and €22 806 ± €3 977 for hybrid procedures. In a regression analysis, procedure duration was the main parameter associated with higher overall TLR costs (coefficient, 2.77; standard error, 0.88; p < .001). The mean cost per operating minute of TLR (indirect, estate costs, all salaried staff present included) was €177 and the mean cost per night stay in hospital (outside intensive care unit) was €356. The mean cost per overnight intensive care unit stay (minimum of 8 hours per night) was €1 193., Conclusion: The main driver of the considerable peri-procedure costs associated with femoropopliteal TLR was procedure time., (Copyright © 2024 The Author(s).

Objective: The objective of this study was to evaluate long-term results of self-expanding vs balloon-expandable hypogastric stent grafts in conjunction with iliac branch devices (IBDs) for aortoiliac aneurysm repair in a multicenter experience (pErformance of iLiac branch deVIces for aneurysmS involving the iliac bifurcation [pELVIS] Registry)., Methods: All patients electively treated for aortoiliac aneurysm with the Cook IBD (Cook Medical, Bloomington, Ind) in nine European centers were reviewed. Clinical and imaging data were prospectively collected in each center, and a multicenter database was created and interrogated. The primary outcome was the primary patency of the IBDs. For the purpose of this investigation, three subgroups were identified: patients receiving a hypogastric balloon-expandable stent graft (BESg); those with a self-expanding stent graft (SESg); and those with any stent graft plus relining with a bare-metal stent (RESg)., Results: Between 2005 and 2017, there were 691 patients who underwent 747 elective endovascular repairs of aortoiliac aneurysms (n = 518 [75.0%]) or isolated iliac aneurysms (n = 173 [25.0%]) with Cook IBDs (n = 56 bilateral) in nine European centers. Mean age was 72 years (range, 41-93 years); 658 (95.2%) patients were male. In 364 patients (52.7%), BESg was used; in 127 (18.4%), SESg; and in 200 (28.9%), RESg. At 30 days, there were 3 (0.4%) perioperative deaths, 3 (0.4%) technical failures, 7 (1.0%) graft thromboses, 30 (4.3%) reinterventions, and 1 (0.1%) conversion to open repair. After a mean follow-up of 32 months (range, 0-128 months), 28 (3.7%) IBD occlusions and 17 (2.3%) IBD-related endoleaks occurred. In 10 patients, iliac diameter increased >5 mm (1.4%). Overall primary patency was 99.2% at 1 month, 97.9% at 12 months, and 95.1% at 72 months. Primary patency was not significantly different in the BESg vs SESg or RESg cohorts (P = .4). During follow-up, there were 126 (18.2%) reinterventions, 93 (13.5%) of which were IBD related, including 11 (1.6%) conversions. Overall, freedom from reintervention and conversion was 90.4% at 12 months and 71.0% at 72 months. IBD-related reinterventions during follow-up in the three cohorts were not significantly different (P = .3) Overall survival was 71.3% at 72 months without differences between the subgroups. At multivariate analysis, aneurysmal hypogastric artery (P < .001; Exp [B] = 4.44) and bilateral treatment (P = .02; Exp [B] = 1.87) were associated with an increase in late failure., Conclusions: In this wide real-world experience, long-term results of endovascular treatment of aortoiliac aneurysms with the IBD are favorable, with a low rate of late graft occlusion and aneurysm-related death. No significant differences in clinical outcomes were observed in patients receiving hypogastric BESg vs SESg or endovascular relining., (Copyright © 2019 Society for Vascular Surgery.

Objective: The chimney/snorkel endovascular aortic repair (ch-EVAR) is gaining ever-greater acceptance in the treatment of pararenal pathologic processes. However, the published experience includes mainly short-term clinical results with combinations of several abdominal devices and types of chimney grafts. The aim of this study was the midterm evaluation of the Endurant stent graft (Medtronic, Santa Rosa, Calif) as a standard abdominal device for ch-EVAR., Methods: Between January 2009 and January 2013, prospectively collected data of high-risk patients with pararenal pathologic processes who underwent ch-EVAR with placement of the Endurant abdominal device were analyzed. The chimney graft intended for use was a balloon-expandable covered stent. Main outcome measures were aneurysm sac regression and chimney graft patency., Results: A total of 187 snorkel/chimney grafts were successfully placed in 128 patients (mean age, 76.6 years). The technical success was 100%. The mean preoperative proximal neck length and aneurysm size were 4.7 mm and 64.8 mm (range, 48-135 mm), respectively. The postoperative new neck length after use of chimney grafts was 18.7 ± 6.3 mm. The mean aneurysm sac decreased significantly (60.8 mm; 95% confidence interval, 2.036-7.084; P = .001) after a mean radiologic follow up of 24.6 ± 17.4 months. Thirty-day mortality and midterm mortality were 0.8% and 17.2%, respectively. Two patients (1.6%) with single chimneys presented with late new onset of type Ia endoleak and underwent additional tube and multiple chimney placement. Primary chimney graft patency was 95.7%. Freedom from chimney graft-related reinterventions was 93.1%., Conclusions: Standard use of the Endurant abdominal device for ch-EVAR in >120 patients is associated with high technical success, significant aneurysm sac regression, and low incidence of secondary procedures after 2-year radiologic follow-up. These results will give significant impetus to device selection, facilitating the standardization of technique., (Copyright © 2016 Society for Vascular Surgery. Published by Elsevier Inc.
