Outcomes after truncal ablation with or without concomitant phlebectomy for isolated symptomatic varicose veins (C2 disease).
This study looked outcomes of patients with varicose veins (C2 disease) who were treated with venous ablation alone or ablation plus phlebectomy using the Vascular Quality Initiative Varicose Vein Registry. Data between January 2015 and March 2015 was used to investigate postoperative as well as long-term clinical and patient-reported outcomes among patients with documented symptomatic C2 disease undergoing truncal endovenous ablations alone and combined ablation and phlebectomy. Out of 3375 patients, 40.1% underwent isolated truncal ablation and the rest had the combined procedure of ablation and phlebectomy. Complications were low for both procedures (8.4% and 8.7%). Overall, improvement in symptoms was experienced by 94.4% of patients with more increases in patients undergoing ablation and phlebectomy than ablation alone. Both procedures are recommended by the authors to be covered by insurance.

Comparison of unilateral vs bilateral and staged bilateral vs concurrent bilateral truncal endovenous ablation in the Vascular Quality Initiative.
This study compares outcomes in patients who have undergone unilateral vs bilateral venous ablation procedures or between staged and concurrent bilateral procedures. Data from the Vascular Quality Initiative from 2015 to 2019 was used to investigate immediate postoperative as well as long-term clinical and patient-reported outcomes. A total of 5029 patients were included, of whom 75.2% underwent unilateral procedures. Follow-up was conducted with a median of 227 days after. Unilateral patients were less likely to be female and white and had lower BMI compared with patients undergoing bilateral procedures. In addition, unilateral patients had fewer prior varicose vein treatments and had higher Venous Clinical Severity Scores (VCSS). There were no differences in complications in patients undergoing unilateral vs bilateral procedures. Systemic complications were rare in both groups.

Indications for spine surgery: validation of an administrative coding algorithm to classify degenerative diagnoses.
The Spine Patient Outcomes Research Trial (SPORT) provided a unique opportunity to examine the validity of a claims-based algorithm for grouping patients by surgical indication. SPORT enrolled patients for lumbar disc herniation, spinal stenosis, and degenerative spondylolisthesis. The researchers found that their claims-based hierarchical coding algorithm of spine-related medical encounters correctly classified more than 90 percent of Medicare patients into their respective SPORT cohorts.

Comparative effectiveness of endovascular and surgical revascularization for patients with peripheral artery disease and critical limb ischemia: systematic review of revascularization in critical limb ischemia.
This systematic review found that there is no difference in clinical outcomes for patients with critical limb ischemia treated with endovascular or surgical revascularization. This review of 23 studies found no differences in overall death, amputation, or amputation-free survival at 2 or more years following treatment.
