We present a case of failed popliteal artery aneurysm repair using a Viabahn stent graft (W. L. Gore & Associates, Flagstaff, Ariz) due to laminated thrombus formation. A 75-year-old man presented with a symptomatic popliteal artery aneurysm. He was treated with a Viabahn stent graft. On follow-up, the patient complained of lower extremity claudication, and duplex ultrasound examination showed a focal intrastent stenosis. A computed tomography scan showed a significant stenosis within the stent graft, at the level of the knee joint creases. The patient underwent superficial femoral artery to distal popliteal surgery. This case report aims to expand on the mechanism of stent graft failure in popliteal aneurysms.

Risk factors for chronic venous disease (CVD) have been widely reported in population health management. However, predisposing factors associated with patients treated for advanced stages of CVD have yet to be established. We examined the demographics and risk factors associated with advanced clinical presentation of CVD for patients referred for vein ablation.Retrospective analysis of our institutional Vascular Quality Initiative Varicose Vein Registry included endovenous laser treatment and radiofrequency ablation procedures at our tertiary institution, community hospital, and outpatient vein clinic between January 2015 and December 2016. All incompetent truncal veins were divided into two groups based on the Clinical, Etiology, Anatomy, and Pathophysiology clinical class of CVD: mild-moderate (C1-C3) and severe (C4-C6). The two groups were compared in terms of their demographics and medical comorbidities using univariate and multivariate analysis. Data analysis was conducted on SPSS 22.0 (IBM Corp, Armonk, NY).During the study period, a total of 650 incompetent truncal veins were ablated. The mean age of patients was 58 years, and 73% were female. Severe CVD composed 21% of the cohort. Male sex was a risk for advanced CVD (odds ratio, 2.6; P .001). Older age was also associated with severe CVD; the average age was 63 years for patients with advanced stage CVD vs 56 years for mild to moderate CVD (P .001). Race, diabetes, body mass index, number of pregnancies, congestive heart failure, history of venous thromboembolism, current anticoagulation, and history of smoking or current smoking status did not affect the severity of CVD.Among patients treated with vein ablation for superficial venous insufficiency, older age and male sex were associated with increased severity of advanced CVD. Despite the higher incidence of varicose veins among women, men are more likely to have clinically advanced CVD when they present for truncal vein ablation.

Introduction The use of telemedicine services may be effective in the perioperative management of patients with varicose veins. Methods Over a seven-month period, patients with varicose veins were evaluated in the virtual clinic via two-way secure videoconferencing or the traditional clinic by the same physician provider. Data sources included institutional Vascular Quality Initiative registry and patient satisfaction surveys. Results Among a total of 121 patients with varicose veins who underwent endovenous catheter ablation of the saphenous vein, 20 patients (16.5%) chose the telemedicine clinic (Group A) and 101 patients (83.5%) chose the traditional clinic (Group B) for their perioperative management. Comparing Group A and Group B, the mean age was 59.2 ± 12.1 versus 59.6 ± 13.0, respectively ( p = 0.944); women were 75% versus 73.3%, respectively ( p = 0.872); African Americans comprised 5% versus 22.8%, while Caucasians comprised 95% versus 63%, respectively ( p = 0.049). Half of the telemedicine patients had multiple virtual visits for a total of 31 virtual encounters. Among telemedicine patients using SurveyMonkey®, 29 telemedicine encounters (93.5%) reported that their virtual visit is “Yes, definitely” or “Yes, somewhat” more convenient over traditional methods. All patients answered that they were able to communicate clearly with the provider, able to have their questions answered, and able to clearly hear and see the provider via telemedicine methods. Discussion Telemedicine services enable another means to deliver high-quality care for patients with venous disease in a safe and coordinated manner. Patients with varicose veins are highly satisfied with the use of telehealth services over the traditional healthcare delivery model.

In-stent stenosis is a frequent complication of superficial femoral artery (SFA) endovascular intervention and can lead to stent occlusion or symptom recurrence. Arterial duplex stent imaging (ADSI) can be used in the surveillance for recurrent stenosis; however, its uniform application is controversial. In this study, we aimed to determine, in patients undergoing SFA stent implantation, whether surveillance with ADSI yielded a better outcome than in those with only ankle-brachial index (ABI) follow-up.We performed a retrospective analysis of all patients undergoing SFA stent implantation for occlusive disease at a tertiary care referral center between 2009 and 2016. The patients were divided into those with ADSI and those with ABI follow-up only. Life-table analysis comparing stent patency, major adverse limb events (MALEs), limb salvage, and mortality between groups was performed.There were 248 patients with SFA stent implantation included, 160 in the ADSI group and 88 in the ABI group. Groups were homogeneous in clinical indications of claudication and critical limb-threatening ischemia (for ADSI, 39% and 61%; for ABI, 38% and 62%; P = .982) and TransAtlantic Inter-Society Consensus class A, B, C, and D lesions (for ADSI, 17%, 45%, 16%, and 22%; for ABI, 21%, 43%, 16%, and 20%; P = .874). Primary patency was similar between groups at 12, 36, and 56 months (ADSI, 65%, 43%, and 32%; ABI, 69%, 34%, and 34%; P = .770), whereas ADSI patients showed an improved assisted primary patency (84%, 68%, and 54%) vs ABI patients (76%, 38%, and 38%; P = .008) and secondary patency. There was greater freedom from MALEs in the ADSI group (91%, 76%, and 64%) vs the ABI group (79%, 46%, and 46%; P .001) at 12, 36, and 56 months of follow-up. ADSI patients were more likely to undergo an endovascular procedure as their initial post-SFA stent implantation intervention (P = .001), whereas ABI patients were more likely to undergo an amputation (P .001).In SFA stent implantation, patients with ADSI follow-up demonstrate an advantage in assisted primary patency and secondary patency and are more likely to undergo an endovascular reintervention. These factors are likely to have effected a decrease in MALEs, indicating the benefit of a more universal adoption of post-SFA stent implantation follow-up ADSI.

Background Current reimbursement policy surrounding telemedicine has been cited as a barrier for the adaptation of this care model. The objective of this study is to analyze the reimbursement figures for outpatient telemedicine consultation in vascular surgery. Methods Patients first underwent synchronous telemedicine visits after receiving point-of-care ultrasound at one of 3 satellite locations of Henry Ford Health System in Michigan. Visit types included new, return, and postoperative patients. Reimbursement information related to payor, adjustment, denial, paid and outstanding balances were recorded for each telemedicine visit. Then, using an enterprise data warehouse, a retrospective analysis was performed for the aforementioned telemedicine visits. The data were analyzed to determine the outcome of total billed charges, number of denied claims, reimbursement per payor, reimbursement per patient, and out-of-pocket costs to the patients. Results Among 184 virtual clinical encounters, the payors included Aetna US Healthcare, Blue Advantage, Blue Cross Blue Shield, Cofinity Plan, Health Alliance Plan, HAP Medicare Advantage, Humana Medicare Advantage, Medicaid, Medicare, Molina Medicaid HMO, United Healthcare, Blue Care Network, Aetna Better Health of Michigan, Priority Health, and self-pay. Among the 15 payors, reimbursement ranged from 0% to 67% of the total charges billed. Among the 184 virtual visits, a grand total of $22,145 was collected or an average of $120.35 per virtual encounter. The breakdown of charges billed was 40% adjusted, 41% paid by insurance, 10% paid by patient, and 13% denied. There were 27 total denials (15%). Denial of payment included telehealth and nontelehealth reasons, citing noncovered charges, payment included for other prior services, new patient quality not met, and not covered by payor. The average out-of-pocket cost to patients was $12.59 per visit. Conclusions These reimbursement data validate the economic potential within this new platform of healthcare delivery. As our experience with the business model grows, we expect to see an increase in reimbursement from private payors and acceptance from patients. Within a tertiary care system, telemedicine for chronic vascular disease has proven to be a viable means to reach a broader population base, and without significant cost to the patients.
