Objective: To compare early and late results of open and endovascular management of popliteal artery aneurysm in a retrospective single-center matched case-control study Methods: From 1981 to 2015, 309 consecutive interventions for popliteal artery aneurysm were performed in our institution, in 59 cases with endovascular repair and in 250 cases with open repair. Endovascular repair was preferred in older asymptomatic patients, while open repair was offered more frequently to patients with a thrombosed popliteal artery aneurysm and a poor run-off status. A one-to-one coarsened exact matching on the basis of the baseline demographic, clinical, and anatomical covariates significantly different between the two treatment options was performed and two equivalent groups of 56 endovascular repairs and open repairs were generated. The two groups were compared in terms of perioperative results with χ2 test and of follow-up outcomes with the Kaplan–Meier curves and log-rank test. Results: There were no differences between the two groups in terms of perioperative outcomes. Median duration of follow-up was 38 months. Five-year survival rates were 94% in endovascular repair group and 89.5% in open repair group (p = 0.4, log-rank 0.6). Primary patency rates at 1, 3, and 5 years were 81%, 78%, and 72% in endovascular repair group and 82.5%, 80%, and 64% in open repair group (p = 0.8, log-rank 0.01). Freedom from reintervention at 5 years was 65.5% in endovascular repair group and 76% in open repair group (p = 0.2, log-rank 1.2). Secondary patency at 1, 3, and 5 years was 94%, 86%, and 74% in endovascular repair group, and 94%, 89%, and 71% in open repair group, respectively (p = 0.9, log-rank 0.01). The rates of limb preservation at 5 years were 94% in endovascular repair group and 86.4% in open repair group (p = 0.3, log-rank 0.8). Conclusion: Open repair and endovascular repair of popliteal artery aneurysms provided in this retrospective single-center experience similar perioperative and follow-up results in equivalent groups of patients.

Objectives Endovascular repair (ER) of popliteal artery aneurysm (PAA) is an alternative to open repair. However, there is no standardized protocol for when to opt for ER and the decision is therefore at the discretion of the clinician. This study aims to evaluate the adherence to the Instruction For Use (IFU) in patients undergoing ER for PAA and factors associated with stent graft patency at one year. Methods The adherence to IFU provided by the manufacturer in 55 patients treated with Gore Viabahn® Endoprosthesis with Heparin Bioactive Surface for PAA between 2009 and 2019 were retrospectively analyzed. Duplex follow-up was performed at 30 days and one year. Results The two groups of patients treated within ( n = 10) and not within ( n = 45) IFU did not differ in patient demographics, diagnostic assessment, treatment or outcome. Forty-five patients (81.8%) received stent graft placement with at least one deviation according to IFU. Distal oversizing >20% was the most frequent deviation against IFU ( n = 22, 40.0%). Primary patency at one year was 72%. Diameter size difference >1 mm between overlapping stent grafts (6/14 [43%], p = 0.013) and renal insufficiency (5/12 [42%], p = 0.0086) were associated with lower primary patency at one year. Age-adjusted analysis of tortuosity index (HR 1.78/SD, 95% CI 1.17–2.71; p = 0.0071) and maximal PAA angle (HR 1.73/SD, 95% CI 1.018–2.95; p = 0.043) were associated with major amputation/mortality at end of follow-up. Conclusion The majority of patients undergoing ER for PAA were not treated within IFU. Diameter size difference >1 mm between overlapping stent grafts was associated with a higher loss of primary patency at one year. Multi-center studies with larger sample size and long-term follow up of patency are warranted.

Aneurysm Repair

With the advent of endovascular repair of aneurysmal disease, length of hospital stay is becoming shorter. Inherent morbidity and problems associated with open repair have been minimized, leading to an improved patient experience. We describe a fairly typical patient with a popliteal artery aneurysm who would be expected to have a protracted recovery from open resection but instead underwent endovascular repair as an outpatient.

Background: Open repair (OR) for popliteal artery aneurysm (PAA) has recently been challenged by endovascular repair (ER) as the primary choice of treatment. The aim of the present study was to evaluate time trends in treatment modality and compare outcomes between OR and ER among electively operated patients after start of screening in 2010 for abdominal aortic aneurysm (AAA), a disease highly associated with PAA. Methods: Between January 1, 2009, and April 30, 2017, 102 procedures and 36 acute and 66 elective repairs for PAA were identified. Results: Over time, a trend ( P = .089) for an increasing elective to acute repair ratio of PAA and an increase in elective ER to OR ratio ( P = .003) was found. Among electively repaired PAAs, the ER group was older ( P = .047) and had a higher ankle–brachial index (ABI; P = .044). The ER group had fewer wound infections ( P = .003), fewer major bleeding complications ( P = .046), and shorter in-hospital stay ( P < .001). After 1 year of follow-up, the ER group had a higher rate of major amputations ( P = .037). Amputation-free survival at the end of follow-up did not differ between groups ( P = .68). Among the 17 patients with PAA eligible for AAA screening, 4 (24%) were diagnosed with PAA through the screening program of AAA. Conclusion: The epidemiology of elective repair of PAA has changed toward increased ER, although ER showed a higher rate of major amputations at 1 year. Confounding was considerable and a randomized trial is needed for evaluation of the best therapeutic option.

Abstract Background: To evaluate the efficacy of a multidisciplinary vocational programme in sick-listed, primary health care patients as compared to matched non-programme patients. Methods: The design was a 3-year prospective population-based, matched case-control study. It was set in a large primary healthcare centre in the city of Eskilstuna, Sweden. The subjects were 943 sickness-certified patients (482 women and 461 men). Intervention: 170 high-risk patients and a matched control group (n = 340) with similar risk for not returning to work within expected time, based on propensity score was created. The intervention group passed a multidisciplinary medical assessment and a coordinated vocational programme, while the control group received usual care by their general practitioner. Main outcome measures: Sick leave conclusion and the day when it occurred. Results: The follow-up time was subdivided into four periods. During the first two periods, days 1–14 and days 15–112 after baseline, the intervention group had a significantly lower sick leave conclusion rate than the control group (hazard ratios, (HR) 0.32, 95% CI 0.20–0.51, p < 0.0001 and 0.47, 95% CI 0.35–0.64). During the third period, days 113–365, the intervention group had an insignificantly lower conclusion rate (HR 0.70, 95% CI 0.46–1.08, p = 0.10), and during the fourth follow-up period, days 366–1096, the intervention group had an insignificantly higher conclusion rate than the control group (HR 1.16, 95% CI 0.69–1.96, p = 0.58). Across the total follow-up period, the intervention group had a lower conclusion rate than the control group (HR 0.55, 95% CI 0.45–0.66, p < 0.0001). Conclusions: No positive significant effects of the rehabilitation programme on time to sick leave conclusion were found.
