Effect of concomitant deep venous reflux on truncal endovenous ablation outcomes in the Vascular Quality Initiative.
This study looked at outcomes for patients with varicose veins (C2 disease) undergoing truncal endovenous ablation with and without deep venous reflux. Data from the Vascular Quality Initiative was analyzed from 2015 to 2019. A total of 4881 patients were included, with 46.2% having combined deep and superficial reflux. Follow-up around a year later (median 336.5 days) was conducted after. Patients with deep reflux were less likely to be female, more likely to be Caucasian, and had no difference in BMI. Additionally, there were no differences in rates of prior varicose vein treatments, number of pregnancies, or history of deep venous thrombosis. However, patients without deep reflux were more likely to use anticoagulants at the time of the procedure. Patients without deep reflux had slightly higher median preprocedural Venous Clinician Severity Score (VCSS) scores as well as postprocedural VCSS scores. Total symptom score was higher for patients without deep reflux before and after the procedure, but there was no change in symptom score after the procedure. Patients with deep reflux had substantially higher rates of complications with a particular increase in proximal thrombus extension.

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.

Trends, perioperative adverse events, and survival of patients with left ventricular assist devices undergoing noncardiac surgery.
This longitudinal cohort study examined outcomes of noncardiac surgery (NCS) in patients with left ventricular assist devices (LVADs). This study examined patients enrolled in Medicare who had undergone durable LVAD implantation from January 2012 to November 2017 with follow-up through December 2017. Primary outcome after NCS was major adverse cardiovascular events (MACEs), defined as in-hospital or 30-day all-cause mortality, ischemic stroke, or intracerebral hemorrhage. Of the 8118 patients with LVAD, 1326 underwent NCS with 75.4% emergent or urgent, and 24.6% elective. Both elective and urgent or emergent NCS was associated with higher mortality early and late compared with patients with LVAD who did not undergo NCS.

Neutrophil-lymphocyte ratio predicts disease severity and outcome after lower extremity procedures.
This study examined the association of neutrophil-lymphocyte ratio (NLR) and complications for patients undergoing interventions for peripheral artery disease (PAD) and other lower extremity conditions. NLR has been associated with higher mortality and other adverse outcomes for those with PAD. The study used inpatients undergoing lower extremity procedures (2008-2016) that were selected from the Cerner Health Facts database (Cerner Corporation, North Kansas City, Mo) using ICD-9 procedure codes. A total of 3687 patients were evaluated, with 2183 undergoing endovascular procedures and 1504 undergoing open procedures. White patients were likely to experience claudication but have less tissue loss. Open procedures had higher NLR rates than endovascular procedures. Preoperative high NLR was strongly associated with in-hospital deaths, cardiac complications, amputation, renal failure, respiratory complications, and prolonged length of stay. Postoperative high NLR values were also associated with more severe PAD.

Pre- and peri-operative factors associated with chronic critical illness in liver transplant recipients.
This study examined whether patients with end-stage liver failure undergoing liver transplant would be at high risk for developing chronic critical illness (CCI). They looked at pre- and perioperative factors associated with CCI. This retrospective cohort study was performed at a large academic transplant center and included all adult liver transplant patients from 2011 to 2017. CCI was defined as the need for mechanical ventilation for seven days or more post-transplant. Recipients who had re-transplantation, acute rejection, or who died during transplant surgery were excluded. They identified 382 transplant recipients, and out of that cohort 45 (11.8%) developed CCI. Eight independent factors were associated with CCI including previous liver transplant, acute renal failure, frailty, lower albumin level, higher international normalized ratio, need for mechanical ventilation and higher systolic pulmonary artery pressure. A higher pre-transplant Model for End-Stage Liver Disease (MELD) score was associated with protection against CCI.

Using cluster analysis to identify patient factors linked to differential functional gains after total knee arthroplasty.
This study used cluster analysis to identify patient factors linked to different outcomes following total knee arthroplasty (TKA). The study analyzed Short Form 36 Physical Component Score (PCS) trajectories of 656 patients at 3 time points over a 1-year period. The MultiExperiment View (MeV) built-in bootstrapping method was used to assess statistical significance of the clusters. They found two distinct clusters: Cluster 1 included 550 patients (84%) who demonstrated persistent improvement at 6 and 12 months. The remainder of patients consisted of Cluster 2 who demonstrated decline in PCS at 6 months but improved by 12 months. Cluster 1 was found to have higher baseline mental health scores, lower baseline PCS, and a significantly higher proportion of non-Hispanic Whites compared to Cluster 2.

Development and validation of a prediction model for pain and functional outcomes after lumbar spine surgery.
The purpose of this study was to assess population-level patient-reported outcome (PRO) response after lumbar spine surgery, and develop/validate a prediction tool for PRO improvement. The study concluded that the PRO response prediction tool, informed by population-level data, explained most of the variability in pain reduction and functional improvement after surgery.

KOOS pain as a marker for significant knee pain two and six years after primary ACL reconstruction: a Multicenter Orthopaedic Outcomes Network (MOON) prospective longitudinal cohort study.
The researchers applied three different models of Knee injury and Osteoarthritis Outcome Score (KOOS) thresholds for significant knee pain to an anterior cruciate ligament reconstruction (ACLR) cohort to identify prevalence and risk factors. They concluded that significant knee pain is prevalent after ACLR; with those who undergo subsequent ipsilateral surgery at greatest risk.
