RESUMO
Endovascular interventions are commonly utilized for treatment of femoropopliteal peripheral artery disease. The relative efficacy of these interventions remains unclear. A Bayesian network meta-analysis was performed comparing 5 endovascular treatment modalities: balloon angioplasty (BA), bare metal stent (BMS), covered stent (CS), drug-coated balloon (DCB), drug-eluting stent (DES) for femoropopliteal peripheral artery disease. The primary efficacy end points were freedom from target lesion revascularization (TLR) and primary patency at 12 months. BA was the reference treatment. Twenty-two trials including 4,381 participants provided data on TLR. Sixteen trials including 3,691 participants provided data on primary patency. Point estimates for DCB suggested that it was the most efficacious treatment for freedom from TLR (odds ratio [OR] 4.23; 95% credible intervals [CrI] 2.43 to 7.66) followed by CS (OR 3.65; 95% CrI 1.11 to 12.55), DES (OR 2.64; 95% CrI 0.72 to 9.77), and BMS (OR 2.3; 95% CrI 1.11 to 4.76). Similarly, point estimates for primary patency were highest with DES (OR 8.93; 95% CrI 3.04, 27.14) followed by CS (OR 3.91; 95% CrI 1.18, 13.84), DCB (OR 3.32; 95% CrI 1.8, 6.25), and BMS (OR 3.5; 95% CrI 1.58, 7.99). In conclusion, DCB has the lowest need for TLR whereas DES has the highest primary patency rate. DCB, CS, and BMS were associated with significant reductions in TLR compared with BA, whereas DCB, DES, CS, and BMS were associated with significantly improved primary patency compared with BA.

BACKGROUND: The optimal revascularization strategy for acute limb ischemia (ALI) remains unclear, and contemporary comparative effectiveness data on endovascular versus surgical revascularization are lacking. METHODS: We used the 2010 to 2014 National Inpatient Sample databases to identify hospitalizations with a primary diagnosis of ALI. Patients were propensity-score matched on the likelihood of undergoing endovascular versus surgical revascularization using a logistic regression model. The primary outcome was in-hospital mortality. Secondary outcomes included myocardial infarction, stroke, composite of death/myocardial infarction/stroke, any amputation, fasciotomy, acute kidney injury, major bleeding, transfusion, vascular complications, length of stay, and hospital costs. RESULTS: Of 10 484 (weighted national estimate=51 914) hospitalizations for ALI, endovascular revascularization was performed in 5008 (47.8%) and surgical revascularization in 5476 (52.2%). In the propensity-score matched cohort (n=7746; 3873 per group), patients who underwent endovascular revascularization had significantly lower in-hospital mortality (2.8% versus 4.0%; P=0.002), myocardial infarction (1.9% versus 2.7%; P=0.022), composite of death/myocardial infarction/stroke (5.2% versus 7.5%; P<0.001), acute kidney injury (10.5% versus 11.9%; P=0.043), fasciotomy (1.9% versus 8.9%; P<0.001), major bleeding (16.7% versus 21.0%; P<0.001), and transfusion (10.3% versus 18.5%; P<0.001), but higher vascular complications (1.4% versus 0.7%; P=0.002), compared with those undergoing surgical revascularization. Rates of any amputation were similar between the 2 groups (4.7% versus 5.1%; P=0.43). Median length of stay was shorter and hospital costs higher with endovascular versus surgical revascularization. CONCLUSIONS: In patients with ALI, endovascular revascularization was associated with better in-hospital clinical outcomes compared with surgical revascularization. Contemporary randomized controlled trials are needed to determine the optimal revascularization strategy for ALI.

OBJECTIVES: This study sought to compare in-hospital major adverse cardiac and cerebrovascular events (MACCE) following endovascular therapy with open surgery for chronic mesenteric ischemia (CMI). BACKGROUND: There are limited contemporary data on in-hospital cardiovascular outcomes among patients with CMI undergoing revascularization via endovascular therapy versus open surgery in the United States. METHODS: Patients with CMI undergoing endovascular or surgical (mesenteric bypass or endarterectomy) revascularization between 2007 and 2014 were identified from the National Inpatient Sample. Weighted national estimates were obtained. Primary and secondary endpoints were MACCE (death, myocardial infarction, stroke, cardiac post-operative complications) and composite in-hospital complications (MACCE + post-operative peripheral vascular complications, gastrointestinal hemorrhage, major bleeding, and bowel resection), respectively. Propensity score matching was used to obtain a balanced cohort of 880 unweighted patients in each group. RESULTS: Of 4,150 patients with CMI, 3,206 (77.2%) underwent endovascular therapy and 944 (22.8%) underwent surgery (weighted national estimates of 15,850 and 4,687, respectively). In the propensity-matched cohort, MACCE and composite in-hospital complications occurred significantly less often after endovascular therapy than surgery (8.6% vs. 15.9%; p < 0.001; and 15.3% vs. 20.3%; p < 0.006). Endovascular therapy was also associated with lower median hospital costs ($20,807.00 [interquartile range: $13,640.20 to $32.754.50] vs. $31,137.00 [interquartile range: $21,680.40 to $52,152.20]; p < 0.001, respectively) and shorter length of stay (5 [interquartile range: 2 to 10] vs. 10 [interquartile range: 7 to 17] days, respectively; p < 0.001) compared with open surgery. CONCLUSIONS: In a large, retrospective analysis of patients with CMI, endovascular therapy remained the dominant revascularization modality, and was associated with lower rates of MACCE, composite in-hospital complications, lower costs, and shorter length of stay compared with surgery.
