Infrapopliteal percutaneous transluminal angioplasty versus bypass surgery as first-line strategies in critical leg ischemia: a propensity score analysis.

Introduction:Recently, endovascular revascularization (percutaneous transluminal angioplasty [PTA]) has challenged surgery as a method for the salvage of critically ischemic legs (CLI). Comparison of surgical and endovascular techniques in randomized controlled trials is difficult because of differences in patient characteristics. To overcome this problem, we adjusted the differences by using propensity score analysis. Materials and Methods:The study cohort comprised 1023 patients treated for CLI with 262 endovascular and 761 surgical revascularization procedures to their crural or pedal arteries. A propensity score was used for adjustment in multivariable analysis, for stratification, and for one-to-one matching. Results:In the overall series, PTA and bypass surgery achieved similar 5-year leg salvage (75.3% vs 76.0%), survival (47.5% vs 43.3%), and amputation-free survival (37.7% vs 37.3%) rates and similar freedom from any further revascularization (77.3% vs 74.4%), whereas freedom from surgical revascularization was higher after bypass surgery (94.3% vs 86.2%, P < 0.001). In propensity-score–matched pairs, outcomes did not differ, except for freedom from surgical revascularization, which was significantly higher in the bypass surgery group (91.4% vs 85.3% at 5 years, P = 0.045). In a subgroup of patients who underwent isolated infrapopliteal revascularization, PTA was associated with better leg salvage (75.5% vs 68.0%, P = 0.042) and somewhat lower freedom from surgical revascularization (78.8% vs 85.2%, P = 0.17). This significant difference in the leg salvage rate was also observed after adjustment for propensity score (P = 0.044), but not in propensity-score–matched pairs (P = 0.12). Conclusions:When feasible, infrapopliteal PTA as a first-line strategy is expected to achieve similar long-term results to bypass surgery in CLI when redo surgery is actively utilized.

Finnvasc score and modified Prevent III score predict long-term outcome after infrainguinal surgical and endovascular revascularization for critical limb ischemia

BACKGROUND Estimation of the risk of adverse long-term outcome is of paramount importance in the treatment of critical limb ischemia (CLI). METHODS We evaluated the accuracy of two specific risk score systems, the Finnvasc score and the modified Prevent III (mPIII) score, in 1425 CLI patients who underwent unilateral, infrainguinal surgical (47.6%) or endovascular (52.4%) revascularization. The receiver operating characteristic (ROC) curve analysis was used to estimate the predictive value of these risk scoring methods. RESULTS The area under the ROC curve of Finnvasc score for prediction of 30-day amputation was 0.609 (95% confidence interval [CI] 0.549-0.677) and of mPIII score 0.533 (95% CI 0.457-0.609). The area under ROC curve of Finnvasc score for prediction of 30-day amputation-free survival was 0.622 (95% CI 0.573-0.671) and of mPIII score 0.588 (95% CI 0.533-0.642). The area under the ROC curve of Finnvasc score for prediction of 1-year amputation-free survival was 0.630 (95% CI 0.597-0.663, P<.0001) and of mPIII score 0.634 (95% CI 0.600-0.667, P<.0001). Finnvasc score predicted leg salvage (relative risk [RR] 1.431, 95% CI 1.319-1.551), survival (RR 1.233, 95% CI 1.116-1.363), and amputation-free survival (RR 1.422, 95% CI 1.319-1.534). mPIII score also predicted leg salvage (RR 1.190, 95% CI 1.108-1.277), survival (RR 1.245, 95% CI 1.193-1.300), and amputation-free survival (RR 1.223, 95% CI 1.176-1.272). CONCLUSIONS Finnvasc and modified PIII risk scoring methods predict long-term outcome of patients undergoing infrainguinal revascularization for CLI. Finnvasc score seems to perform well also in predicting immediate postoperative outcome.

Infrainguinal percutaneous transluminal angioplasty or bypass surgery in patients aged 80 years and older with critical leg ischaemia

Infrainguinal revascularization for critical leg ischaemia (CLI) in patients aged 80 years and over is associated with increased operative risk. The aim was to compare the results of percutaneous transluminal angioplasty (PTA) and bypass surgery in these patients.

Femoropopliteal balloon angioplasty vs. bypass surgery for CLI: a propensity score analysis.

OBJECTIVES To compare the outcomes of femoropopliteal percutaneous transluminal angioplasty (PTA) and bypass surgery for critical limb ischaemia (CLI). DESIGN The study is retrospective in nature. MATERIALS AND METHODS This study included 858 consecutive patients, who underwent femoropopliteal revascularisation for CLI at Helsinki University Central Hospital during 2000-2007. As many as 517 patients (60%) underwent PTA and 341 (40%) bypass surgery. Propensity score analysis was used for risk adjustment in multivariable analysis and for one-to-one matching. RESULTS In the overall series, PTA had poorer long-term results than bypass (5-year leg salvage, 78.2% vs. 91.8%, p < 0.0001; survival 49.2% vs. 57.1%, p = 0.048; amputation-free survival, 42.0% vs. 53.7%, p = 0.003; freedom from surgical re-intervention 86.2% vs. 94.3%, p < 0.0001). When treatment method was adjusted for propensity score as well as in the propensity score-matched pairs, leg salvage and freedom from surgical re-intervention were worse after PTA than after bypass (among the 241 propensity score-matched pairs, 74.3% vs. 88.2%, p = 0.031, and 86.1% vs. 89.8%, p = 0.025, respectively). Differences in survival, amputation-free survival and freedom from any re-intervention were not observed. CONCLUSIONS In CLI patients, femoropopliteal PTA seems to be associated with poorer long-term leg salvage and freedom from surgical re-intervention than bypass surgery. However, the treatment method did not affect long-term amputation-free survival.

Rupture of Abdominal Aortic Aneurysms in Patients Under Screening Age and Elective Repair Threshold

OBJECTIVES The objective of this study was to identify the proportion of abdominal aortic aneurysm ruptures that occur before the screening age or threshold diameter for operative repair is reached. METHODS The study was a retrospective analysis of RAAA patients including all RAAA patients admitted to Helsinki (HUH) and Tampere University Hospitals (TaUH) during 2002-2013. The data for age, gender, and comorbidities were collected from vascular registry and patient records. Computed tomography images taken at the time of admission were used for the measurement of maximum anteroposterior (AP) aneurysm diameter at the time of rupture. Age and diameter data were compared with risk factors. RESULTS A total of 585 patients diagnosed with RAAA were admitted to the two hospitals during the 12 year period. The mean age at the time of rupture was 73.6 years (SD 9.5, range 42-96 years). 18.3% of patients were under 65: 21.4% of men and 3.0% of women. Men were on average 8 years younger than women. The odds ratio (OR) for rupture before 65 years of age for smokers was 2.1 compared with non-smokers, and 28.4% of smokers were under 65 at the time of rupture. Of all RAAA patients, 327 had a computed tomography scan confirming rupture. The mean AP diameter of the aneurysm was 75.6 mm (SD 15.8, range 32-155 mm). The mean size was significantly lower in women than in men (70.5 vs. 76.8, p = .005). CONCLUSIONS The data from this study show that a fifth of men would not make it to the screening age of 65 before AAA rupture, the proportion being even larger in active smokers. The data from this study also supports the previous finding that aneurysm size at the time of rupture is significantly smaller in women.

Quality of life and costs of levonorgestrel-releasing intrauterine system or hysterectomy in the treatment of menorrhagia: a 10-year randomized controlled trial

OBJECTIVE Menorrhagia is a common problem impairing the quality of life (QOL) of many women. Both levonorgestrel-releasing intrauterine system (LNG-IUS) and hysterectomy are effective treatment modalities but no long-term comparative studies of QOL and costs exist. The objective of this study was to compare QOL and costs of LNG-IUS or hysterectomy in the treatment of menorrhagia during 10-year follow-up. STUDY DESIGN A total of 236 women, aged 35-49 years, referred for menorrhagia to 5 university hospitals in Finland were randomly assigned to treatment with LNG-IUS (n = 119) or hysterectomy (n = 117) and were monitored for 10 years. The main outcome measures were health-related QOL (HRQOL), psychosocial well-being, and cost-effectiveness. RESULTS A total of 221 (94%) women were followed for 10 years. Although 55 (46%) women assigned to the LNG-IUS subsequently underwent hysterectomy, the overall costs in the LNG-IUS group (

4937). Overall, levels of HRQOL and psychosocial well-being improved during first 5 years but diminished between 5 years and 10 years and the improved HRQOL returned close to the baseline level. There were no significant differences between LNG-IUS and hysterectomy groups. CONCLUSION Both LNG-IUS and hysterectomy improved HRQOL. The improvement was most striking during the first 5 years. Although many women eventually had hysterectomy, LNG-IUS remained cost-effective.
