ABSTRACT

OBJECTIVES: The Patient Protection and Affordable Care Act (ACA), fully implemented by 2015, has significantly increased the number of Americans with health insurance. However, its impact on physician reimbursement (PR) is not well studied. Our objective was to determine the ACA's impact on the professional component of PR for selected vascular surgery (VS) procedures and vascular laboratory (VL) studies at our institution. METHODS: PR for the following 5 VS procedures and 4 VL studies were obtained from our billing department: CPT 34803 (Endovascular aortic repair, EVAR), 35301 (carotid endarterectomy, CEA), 35656 (lower extremity bypass, LEB), 36010 (introduction of catheter into vena cava, ICVC), 36200 first, 93922 (ankle brachial index, ABI), 93925 (lower extremity arterial duplex, LEA duplex), 93970 (lower extremity venous duplex, LEV Duplex), and 93990 (hemodialysis duplex). The data was organized by payer: Medicare, Medicaid, Commercial Insurers (CI), and Other. PR was studied pre-ACA (January 2008 through December 2009) and post-ACA (January 2015 through December 2016). The post-ACA PR and inflation adjusted reimbursement (IAR) in 2016 dollars using the consumer price index (CPI) were calculated and compared using one-sample t-test. The percent difference between the post-ACA PR and IAR was also compared. RESULTS: PR for 1,637 VS procedures and 16,333 VL studies was analyzed. The post-ACA PR was significantly lower than the IAR for most Medicare and Medicaid procedures. For EVAR, post-ACA reimbursement was overall on par with the IAR but significantly lower for Medicare. For CEA, post-ACA reimbursement was overall lower than IAR. For LEB, overall average PR was lower than IAR, with statistically significant lower Medicare and Medicaid (P < 0.001) payments. For ICAo, overall PR was significantly lower than the IAR and this was true across all insurance types. In contrast, for ICV, the post-ACA reimbursement was higher than IAR for all payers but did not reach statistical significance (P = 0.25). The post-ACA PR was significantly higher than the IAR for most VL studies, except for Medicare PR. The percent change for VS procedures were mostly negative for the Medicaid and Medicare groups. This results in potential annual shortcomings of $2, 862 and $20,923 respectively. CONCLUSION: When comparing reimbursement before and after ACA implementation, Medicare and Medicaid PR for most VS procedures has not kept up with inflation. However, for most VL procedures, PR has exceeded inflation. Further efforts are needed to support Vascular Surgery reimbursement including higher valuation of the Medicare Conversion factor.

ABSTRACT

Popliteal artery entrapment syndrome (PAES) is an uncommon condition that causes recurrent posterior leg pain and foot paresthesia in running athletes. This condition occurs most commonly due to an accessory or abnormal implant of the medial head of the gastrocnemius muscle. It may mimic or coincide with other chronic conditions of the lower extremity including chronic exertional compartment syndrome but is most consistent with vascular claudication. Clinical features that distinguish PAES from other causes of leg pain include a sensation of coolness of the posterior leg during exercise and associated paresthesia of the plantar aspect of the foot. Physical examination often reveals decreased intensity of the posterior tibial or dorsalis pedis pulses with passive dorsiflexion or active plantarflexion of the ankle. Diagnostic tests that confirm the presence of PAES include lower extremity angiography during active resisted plantarflexion or maximal passive dorsiflexion, and magnetic resonance angiography done after exercise provocation. Nonsurgical treatment with physical therapy and stretching of the gastrocnemius complex should be done as the first line of treatment. When conservative treatments are ineffective, referral to a vascular specialist for surgical intervention with a muscular band excision or transection, vascular bypass, or arterial reconstruction is necessary.

ABSTRACT

The global SARS-CoV-2/COVID-19 pandemic has required a reduction in nonemergency treatment for a variety of disorders. This report summarizes conclusions of an international multidisciplinary consensus group assembled to address evaluation and treatment of patients with thoracic outlet syndrome (TOS), a group of conditions characterized by extrinsic compression of the neurovascular structures serving the upper extremity. The following recommendations were developed in relation to the three defined types of TOS (neurogenic, venous, and arterial) and three phases of pandemic response (preparatory, urgent with limited resources, and emergency with complete diversion of resources). • In-person evaluation and treatment for neurogenic TOS (interventional or surgical) are generally postponed during all pandemic phases, with telephone/telemedicine visits and at-home physical therapy exercises recommended when feasible. • Venous TOS presenting with acute upper extremity deep venous thrombosis (Paget-Schroetter syndrome) is managed primarily with anticoagulation, with percutaneous interventions for venous TOS (thrombolysis) considered in early phases (I and II) and surgical treatment delayed until pandemic conditions resolve. Catheter-based interventions may also be considered for selected patients with central subclavian vein obstruction and threatened hemodialysis access in all pandemic phases, with definitive surgical treatment postponed. • Evaluation and surgical treatment for arterial TOS should be reserved for limb-threatening situations, such as acute upper extremity ischemia or acute digital embolization, in all phases of pandemic response. In late pandemic phases, surgery should be restricted to thrombolysis or brachial artery thromboembolectomy, with more definitive treatment delayed until pandemic conditions resolve.

ABSTRACT

BACKGROUND: The Medicare Access and CHIP Reauthorization Act (MACRA) brings with it increased regulatory requirements not traditionally addressed by standard vascular laboratory accreditation, which is based on accuracy. The new quality improvement project of the Intersocietal Accreditation Commission (IAC) may satisfy an improvement activity (IA) of the MACRA. We hypothesize that other IAs in the MACRA such as timeliness of test results or patient care quality performance requirements can be met by analyzing data already being collected by the vascular laboratory. After a process improvement strategy, we chose to review progress in our vascular laboratory related to time to interpretation (TI), patient check-in to study completion (study time), wait time for first available outpatient venous duplex scan (wait time), technologist productivity, and critical results reporting. METHODS: Data from our hospital-based vascular laboratory were collected from 2010 to 2016. TI was collected through our reporting software VascuPro (Consensus Medical), and study time and wait time were obtained from electronic medical records (EMR) (Epic). Technologist productivity was calculated by commercially available productivity tools, and compliance with critical results reporting was calculated quarterly as per our quality assurance program. Appropriateness of carotid duplex scan testing was performed by expert review of International Classification of Disease codes used to request the test. RESULTS: TI analysis comprised 91,352 studies with a mean of 3.3 hr between test completion and final interpretation. The TI improved from 5.0 to 2.1 hr on weekdays and was longer on weekends (4.9 hr; P < 0.001). The study time improved from 29.8 to 27.2 min and was 14.9 min shorter on the weekends (P < 0.001). The wait time ranged from a mean of 1-2.08 days. Technologist productivity improved from 90.7% to 93.6%. Critical results reporting quarterly audits showed a 100% compliance rate. On expert review, the International Classification of Disease code on carotid duplex scan requests in the EMR was deemed inaccurate in 17.4% of cases. CONCLUSIONS: TI and study time improved; wait time and critical results reporting remained steady. Most of the data are readily available in a vascular laboratory standard EMR. The plan-do-study-act (PDSA or Shewhart Cycle) principle is critical to process improvement and needed as we transition from traditional accreditation mostly based on test accuracy to one demanding efficiency, timeliness, patient satisfaction, productivity, accountability, and appropriateness of testing. Process improvement studies will improve patient care and satisfaction, increase efficiency and throughput, while satisfying changing IAC standards and preparing for upcoming regulatory requirements of the MACRA.

ABSTRACT

Controversies in the treatment of venous thoracic outlet syndrome (VTOS) have been discussed for decades, but still persist. Calls for more objective reporting standards have pushed practice towards comprehensive venous evaluations and interventions after first rib resection (FRR) for all patients. In our practice, we have relied on patient-centered, patient-reported outcomes to guide adjunctive treatment and measure success. Thus, we sought to investigate the use of thrombolysis versus anticoagulation alone, timing of FRR following thrombolysis, post-FRR venous intervention, and FRR for McCleery syndrome (MCS) and their impact on patient symptoms and return to function. All patients undergoing FRR for VTOS at our institution from 4 April 2000 through 31 December 2013 were reviewed. Demographics, symptoms, diagnostic and treatment details, and outcomes were collected. Per "Reporting Standards of the Society for Vascular Surgery for Thoracic Outlet Syndrome", symptoms were described as swelling/discoloration/heaviness, collaterals, concomitant neurogenic symptoms, and functional impairment. Patient-reported response to treatment was defined as complete (no residual symptoms and return to function), partial (any residual symptoms present but no functional impairment), temporary (initial improvement but subsequent recurrence of any symptoms or functional impairment), or none (persistent symptoms or functional impairment). Sixty FRR were performed on 59 patients. 54.2% were female with a mean age of 34.3 years. Swelling/discoloration/heaviness was present in all but one patient, deep vein thrombosis in 80%, and visible collaterals in 41.7%. Four patients had pulmonary embolus while 65% had concomitant neurogenic symptoms. In addition, 74.6% of patients were anticoagulated and 44.1% also underwent thrombolysis prior to FRR. Complete or partial response occurred in 93.4%. Of the four patients with temporary or no response, further diagnostics revealed residual venous disease in two and occult alternative diagnoses in two. Use of thrombolysis was not related to FRR outcomes (p = 0.600). Performance of FRR less than or greater than six weeks after the initiation of anticoagulation or treatment with thrombolysis was not related to FRR outcomes (p = 1). Whether patients had DVT or MCS was not related to FRR outcomes (p = 1). No patient had recurrent DVT. From a patient-centered, patient-reported standpoint, VTOS is equally effectively treated with FRR regardless of preoperative thrombolysis or timing of surgery after thrombolysis. A conservative approach to venous interrogation and intervention after FRR is safe and effective for symptom control and return to function. Additionally, patients with MCS are effectively treated with FRR.

ABSTRACT

INTRODUCTION: Ultrasound-guided thrombin injection (UGTI) is a well-established practice for the treatment of femoral artery pseudoaneurysm. This procedure is highly successful but dependent on appropriate pseudoaneurysm anatomy and adequate ultrasound visualization. Morbid obesity can present a significant technical challenge due to increased groin adiposity, resulting in poor visualization of critical structures needed to safely perform the procedure. We aim to evaluate the safety and efficacy of UGTI to treat femoral artery pseudoaneurysm in the morbidly obese. METHODS: This is a retrospective cohort study in which all patients who underwent UGTI at The Ohio State University Ross Heart Hospital from 2009 to 2014 were analyzed for patient characteristics and stratified by body mass index (BMI). Patients with BMI ≥ 35 were considered morbidly obese and were compared to patients with a BMI < 35. Outcome was failed treatment resulting in residual pseudoaneurysm. RESULTS: Our cohort consisted of 54 patients who underwent thrombin injection. There were 41 nonmorbidly obese and 13 morbidly obese patients. Mean age was 64.5 years. The cohort was 44.4% male. There were 6 failures, of which 1 underwent successful repeat injection and 5 underwent open surgical repair. There was no statistically significant difference in failure between nonmorbidly obese and morbidly obese patients (9.8% vs 15.4%, P = .45). There were no embolic/thrombotic complications. CONCLUSION: Ultrasound-guided thrombin injection is a safe and effective therapy in the morbidly obese for the treatment of femoral artery pseudoaneurysm. In the hands of experienced sonographers and surgeons with adequate visualization of the pseudoaneurysm sac, UGTI should remain a standard therapy in the morbidly obese.

ABSTRACT

BACKGROUND: We present 6 patients who had operative repair of symptomatic popliteal cystic adventitial disease (pCAD). Developmental theories for pCAD and surgical alternatives are presented. METHODS: All patients who had repair of pCAD over the past 3 years are included. RESULTS: Three patients had cyst excision alone, whereas the remaining 3 had cyst and artery excision with interposition vein grafting. Cyst recurrence occurred in 2 patients who had cyst excision alone. Four of the patients had a patent communication between the cyst and the joint capsule. CONCLUSIONS: Our small series suggests that the articular (synovial) theory of development may be the most likely and that cyst and artery excision with interposition vein grafting may be preferred over cyst excision alone.

ABSTRACT

OBJECTIVE: Abdominal aortic aneurysm (AAA) wall stiffness has been suggested to be an important factor in the overall rupture risk assessment compared with anatomic measure. We hypothesize that AAA diameter will have no correlation to AAA wall stiffness. The aim of this study is to (1) determine magnetic resonance elastography (MRE)-derived aortic wall stiffness in AAA patients and its correlation to AAA diameter; (2) determine the correlation between AAA stiffness and amount of thrombus and calcium; and (3) compare the AAA stiffness measurements against age-matched healthy individuals. METHODS: In vivo abdominal aortic MRE was performed on 36 individuals (24 patients with AAA measuring 3-10 cm and 12 healthy volunteers), aged 36 to 78 years, after obtaining written informed consent under the approval of the Institutional Review Board. MRE images were processed to obtain spatial stiffness maps of the aorta. AAA diameter, amount of thrombus, and calcium score were reported by experienced interventional radiologists. Spearman correlation, Wilcoxon signed rank test, and Mann-Whitney test were performed to determine the correlation between AAA stiffness and diameter and to determine the significant difference in stiffness measurements between AAA patients and healthy individuals. RESULTS: No significant correlation (P > .1) was found between AAA stiffness and diameter or amount of thrombus or calcium score. AAA stiffness (mean 13.97 ± 4.2 kPa) is significantly (P ≤ .02) higher than remote normal aorta in AAA (mean 8.87 ± 2.2 kPa) patients and in normal individuals (mean 7.1 ± 1.9 kPa). CONCLUSIONS: Our results suggest that AAA wall stiffness may provide additional information independent of AAA diameter, which may contribute to our understanding of AAA pathophysiology, biomechanics, and risk for rupture.

ABSTRACT

Axillary-femoral bypass is sometimes performed for complex aortoiliac occlusive disease in patients unfit for aortic surgery or in those with aortic infection. Typically, older patients with medical comorbidities that commonly accompany atherosclerotic or aneurysmal disease are involved and can tolerate the theoretic risk of limited flow volume associated with long, small diameter, axillary-femoral grafts. However, a subset of younger, healthier, more vigorous patients outside the typical atherosclerotic or aneurysmal demographic occasionally come to axillary-femoral bypass and may experience symptoms of distal hypoperfusion if flow volumes cannot meet demand. We present a series of patients with primary aortic infection treated with aortic ligation and axillary-femoral bypass, who then progressed to symptoms of visceral, spinal, or extremity ischemia from inadequate distal perfusion.

ABSTRACT

OBJECTIVE: Iron has been implicated in atherogenesis and plaque destabilization, whereas less is known about iron-related proteins in this disease. We compared ex vivo quantities with in vivo vessel wall T2*, which is a noncontrast magnetic resonance relaxation time that quantitatively shortens with increased tissue iron content. We also tested the hypothesis that patients with carotid atherosclerosis have abnormal T2* times vs controls that would help support a role for iron in human atherosclerosis. METHODS: Forty-six patients undergoing carotid endarterectomy and 14 subjects without carotid disease were prospectively enrolled to undergo carotid magnetic resonance imaging. Ex vivo measurements were performed on explanted plaque and 17 mammary artery samples. RESULTS: Plaques vs normal arteries had higher levels of ferritin (median, 7.3 [interquartile range (IQR), 4-13.8] vs 1.0 [IQR, 0.6-1.3] ng/mg; P < .001) and oxidized low-density lipoprotein (median, 0.17 [IQR, 0.12-0.30] vs 0.01 [IQR, 0.003-0.03] ng/mg; P < .001) as well as hepcidin (median, 8.7 [IQR, 4.6-12.4] vs 2.6 [IQR, 1.3-7.0] ng/mL; P = .03); serum hepcidin levels did not distinguish atherosclerosis patients from controls (median, 40.6 [IQR, 18.8-88.6] vs 33.9 [IQR, 17.6-55.2]; P = .42). Shorter in vivo T2* paralleled larger plaque volume (ρ = -.44; P = .01), and diseased arteries had shorter T2* values compared with controls (median, 17.7 ± 4.3 vs 23.0 ± 2.4 ms; P < .001). CONCLUSIONS: Diseased arteries have greater levels of iron-related proteins ex vivo and shorter T2* times in vivo. Further studies should help define the role of T2* as a biomarker of iron and atherosclerosis.

ABSTRACT

Carotid body tumors represent the most common of head and neck tumors. They account for <0.03% of all human tumors. The underlying physiology and pathogenesis of this tumor type are not well understood. Several different genetic abnormalities have been associated with the development of carotid body paragangliomas. We present a case report with an unusual genetic mutation in the SDHB gene and a review of the paraganglioma syndromes.

ABSTRACT

Noninvasive vascular diagnostic testing is efficient and cost-effective, and it is an integral part of vascular surgery practice. Integration of the laboratory into the practice can add significant income to a practice as well as increase the quality of the patient's experience. Maintaining a successful vascular laboratory is a key component of the practice's remaining competitive in an ever-changing health care system. Attention must be paid to staffing, operations, financial performance, revenue cycle, and patient and referring physician satisfaction to grow the business.

ABSTRACT

The midaortic syndrome (MAS) refers to descending thoracic and abdominal aortic coarctation, which is rare and most common in the pediatric population. Open surgical repair, often with aortoaortic bypass, remains a highly effective treatment and is traditionally thought to be definitive despite concerns over patient growth postoperatively. This article presents 2 cases of MAS treated with aortoaortic bypass who developed long-term complications, one related to patient growth and the other to graft-enteric fistula. Consideration must be given to patient growth at operation for MAS, and long-term follow-up is necessary to identify other complications.

ABSTRACT

PURPOSE: To determine diversity in the membership and analyze representation of private practitioners and ethnic and racial minorities/women in senior leadership roles in a regional vascular society. METHODS: The program book distributed at the 2008 annual meeting was used to compile information on membership categories, academic status, gender, and ethnic origin of members. Excluded from further analysis were all but active and senior members (n = 386). Officers for President and current President-Elect (P, n = 31), Secretary (S, n = 10), Treasurer (T, n = 11), and Councilor (C, n = 33) over a 30-year period were scrutinized for similar information. Members were considered to be "academic" if they worked full time at an academic medical center or as faculty at a teaching hospital with a vascular fellowship and national recognition. Private practice (PP) or academic practice (AP) was determined by personal knowledge, mailing address, e-mail address, and search engines. Ethnic and racial origin was determined by name, personal knowledge, or a web search. RESULTS: Of the 386 active and senior members in the society, 86% were white, 13.7% were of various ethnic/racial groups, and 5.7% were women. Sixty-eight percent of members were in PP. Female members were more likely to be in AP compared with male members (68.1% vs 29.6%, P <.0002). White males made up 89.4% of all officers and 94.2% of all senior positions over the 30 years of the society. Seventy officer positions were occupied by those in AP (82.3%) vs 15 positions (18%) for the PP group. For the senior positions, 92.3% were from the AP group compared with the 8% from the PP group. (P < .0036) White male academics (WMAs) (23.7% of membership) occupied 86% of all senior leadership and 57% of C positions compared with 13% and 42%, respectively, for the rest of the membership (P < .0041). Of the 33 C positions, 66.6% were filled by members in AP. Of these 22 AP Councilors, 11 (50%) then moved up to senior leadership positions compared with two of 11 (18%) PP councilors (P = .07). CONCLUSIONS: Ethnic and racial minorities and women are under represented in the membership compared with the general population, medical school graduates, and faculty. PPs and non-white male academics are under represented in senior leadership positions. With changing demographics, a predicted shortage of vascular surgeons, the need for role models in leadership positions and a push to culturally competent care, regional and national societies must change course and promote a more diverse membership and representative senior leadership.

ABSTRACT

BACKGROUND: Little is known about the ideal residual length of the great saphenous vein (GSV) stump and its potential role in complications such as acute deep venous thrombosis (DVT) and recanalization. This study was designed to learn about the natural history of the residual GSV stump length following endovenous laser treatment. METHODS: Prospective data were collected from 50 limbs of 50 patients over an 11-month period. Clinical assessment and duplex ultrasound were performed preoperatively, at 24 hours and at 3 months after the procedure. RESULTS: The residual GSV stump decreased in length from a mean of 15 mm at 24 hours to 13 mm at 3 months after the procedure. None of the patients developed acute DVT or proximal recanalization when the laser tip was positioned 28 mm distal to the saphenofemoral junction. CONCLUSION: Endovenous laser therapy of the GSV for symptomatic reflux is safe and effective. The residual GSV stump decreased in length over a 3-month period.

ABSTRACT

We recently demonstrated that mitochondrial nitric oxide synthase (mtNOS) functionally couples with mitochondrial respiratory chain complex I to produce nitric oxide [M.S. Parihar, R.R. Nazarewicz, E. Kincaid, U. Bringold, P. Ghafourifar, Association of mitochondrial nitric oxide synthase activity with respiratory chain complex I, Biochem. Biophys. Res. Commun. 366 (2008) 23-28]. The present report shows that inactivation of complex I leads mtNOS to become pro-oxidative. Our findings suggest a crucial role for mtNOS in oxidative stress caused by mitochondrial complex I inactivation.

ABSTRACT

The present study investigated the effect of a ketogenic diet on the blood redox status of healthy female subjects. Twenty healthy females with mean body mass index of 21.45 +/- 2.05 kg/m(2) were provided a low-carbohydrate (55 +/- 6 g; 13% total energy), high-fat (138 +/- 16 g; 74% total energy), calorie-restricted (-465 +/- 115 kcal/d) diet. The followings were tested prior to and after 14 days consumption of the diet: Whole body, body weight and total body fat; blood, complete blood count, red blood cells, white blood cells, hemoglobin, and hematocrit; plasma, 3-beta-hydroxybutyrate, total antioxidative status, and uric acid; red blood cells, total sulfhydryl content, malondialdehyde, superoxide dismutase activity, and catalase activity. After 14 days, weight loss was significant whereas no changes were detected in body fat. No alterations were observed in blood count or morphology. 3-beta-hydroxybutyrate, total antioxidative status, uric acid, and sulfhydryl content were significantly increased. There were no alterations in malondialdehyde, or superoxide dismutase or catalase activity. The present study demonstrates that 14 days of a ketogenic diet elevates blood antioxidative capacity and does not induce oxidative stress in healthy subjects.

ABSTRACT

This report describes a new approach for management of iliac vein injury. These injuries are often difficult to expose, and the associated hemorrhage further hinders visualization and subsequent repair. In this case, the use of an endovascular balloon from groin access controlled venous hemorrhage and permitted a primary repair of a torn left iliac vein. We believe that this approach is unique in that it uses a compliant, low-pressure balloon, thus preventing further iatrogenic injury in otherwise fragile venous structures and allowing direct access to the tear when exposure in the operative field is limited.

ABSTRACT

BACKGROUND: Ischemic ulcerations of the distal lower extremities are a manifestation of chronic critical limb ischemia. Without restoration of arterial flow, subsequent gangrene and limb loss can ensue. Unfortunately, revascularization is not always possible. METHODS: A literature search of MEDLINE was performed and a case series of 5 patients with lower extremity ischemic ulcerations is described. RESULTS AND CONCLUSION: Five patients with severe peripheral artery disease had nonhealing lower extremity ischemic ulcerations. Because 3 patients were not ideal candidates for percutaneous or surgical intervention, and 2 refused invasive therapy, they were treated with cilostazol. Between 7 and 24 weeks after beginning cilostazol therapy, the ulcerations healed in all 5 patients. Three of the patients experienced resolution of concurrent ischemic rest pain. One patient underwent a posttreatment noninvasive arterial study that documented improved large- and small-vessel perfusion. The antiplatelet, antithrombotic, and vasodilatory effects, in addition to possible unrecognized actions of cilostazol, appeared to promote wound healing in this small group of patients with chronic critical limb ischemia. When revascularization is not ideal therapy for ischemic ulcers, a pharmacologic approach with cilostazol might induce healing and obviate limb amputation.
