A contemporary reassessment of the US surgical workforce through 2050 predicts continued shortages and increased productivity demands.

BACKGROUND: We aimed to predict practicing surgeon workforce size across ten specialties to provide an up-to-date, national perspective on future surgical workforce shortages or surpluses. METHODS: Twenty-one years of AMA Masterfile data (1997-2017) were used to predict surgeons practicing from 2030 to 2050. Published ratios of surgeons/100,000 population were used to estimate the number of surgeons needed. MGMA median wRVU/surgeon by specialty (2017) was used to determine wRVU demand and capacity based on projected and needed number of surgeons. RESULTS: By 2030, surgeon shortages across nine specialties: Cardiothoracic, Otolaryngology, General Surgery, Obstetrics-Gynecology, Ophthalmology, Orthopedics, Plastics, Urology, and Vascular, are estimated to increase clinical workload by 10-50% additional wRVU. By 2050, shortages in eight specialties are estimated to increase clinical workload by 7-61% additional wRVU. CONCLUSIONS: If historical trends continue, a majority of surgical specialties are estimated to experience workforce deficits, increasing clinical demands substantially.

Personality Predicts the Efficacy of a Physician Leadership Development Program.

It is imperative for health care organizations to foster leadership skills in their workforce. Leadership development programs offer a potential mechanism to achieve this goal. These development programs are likely not equally effective for all participants. This study evaluates the efficacy of one such program and determines personality predictors of its efficacy. Before and after a 12-month leadership development program, 28 physicians from various disciplines completed self-reported measures of leadership knowledge across 3 domains. At baseline, participants also provided personality data across the Big-5 factors of personality as well as 2 narrow facets (learning-goal orientation and preference for collaboration). Results suggest that leadership development programs can increase knowledge across leadership domains. Extraversion and conscientiousness predict changes in knowledge. Learning-goal-orientation and preference for collaboration personality facets provide incremental predictive power. Leadership development programs can improve self-rated knowledge across a range of leadership domains and is differentially effective for people based on their personalities.

Physician Reimbursement for Vascular Surgery Procedures and Vascular Laboratory Studies Before and After the Affordable Care Act.

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.

The continued urbanization of American surgery: A threat to rural hospitals.

BACKGROUND: In 2011, we predicted that surgeon shortages for rural hospitals would contribute to closures of rural hospitals. Here, we update population trends, the distribution of rural and urban hospitals, and surgeon supply to estimate surgeon demand for rural and urban hospital settings by 2040. METHODS: Surgeon supply was based on new certifications for general surgery, orthopedic surgery, and obstetrics and gynecology adjusted for retirement. Surgeon demand from 2020 to 2040 was projected based on the US Census and published practice ratios: general surgery 10.7/100,000, orthopedic surgery 7.9/100,000, and obstetrics and gynecology 13.0/100,000. RESULTS: The US population grew from 309 million in 2011 to 327 million in 2017 with rural populations unchanged at 56 million. By 2040, the US population will be 374 million (urban 85% and rural 15%) creating shortages of general surgery (-31.5%), orthopedic surgery (-34.3%), and obstetrics and gynecology (-25.3). Future hiring needs for urban hospitals will be 5 times greater than rural hospitals. Urban hospitals will likely recruit most newly certified surgeons. CONCLUSION: Increases in surgery trainees will not meet the demand. The continued urbanization of American surgery may push rural hospitals into a vicious financial cycle leading to additional closures of rural hospitals and worsening issues of access. An alternative training paradigm for the rural surgeon is recommended to meet the unique demands of rural hospitals.

The financial and employment effects of coronavirus disease 2019 on physicians in the United States.

Although the coronavirus disease 2019 (COVID-19) pandemic has created havoc with the U.S healthcare system and physicians, the financial and contractual implications for physicians are now beginning to come to the forefront. Financial assistance from the federal government has mainly been received by hospitals, which have borne the brunt of the COVID-19 illness. Some physician groups have, or are, receiving assistance through a few programs, although the accelerated and advance payments have been suspended. Employed surgeons are now being furloughed, terminated, or persuaded to agree to a significant cut in pay, forego bonuses, or take leave without pay as healthcare systems and some physician groups have started to experience the consequences of halting elective procedures. Newly hired surgeons might be forced in a few cases to agree to delays in starting their employment, new amendments, changes in employment status, and other terms for fear of losing their employment. In the present report, we have explained some agreement terminology and options available to allow physicians to understand the terms of their employment agreement and make their decisions after consulting with an expert healthcare attorney.

COVID-19 financial resources for physicians.

The appropriate focus in managing the COVID-19 pandemic in the United States has been addressing access and delivery of care to the population affected by the outbreak. All sectors of the U.S. economy have been significantly affected, including physicians. Physician groups of all specialties and sizes have experienced the financial effects of the pandemic. Hospitals have received billions of dollars to support and enable them to manage emergencies and cover the costs of the disruption. However, many vascular surgeons are under great financial pressure because of the postponement of all nonemergency procedures. The federal government has announced a myriad of programs in the form of grants and loans to reimburse physicians for some of their expenses and loss of revenue. It is more than likely that unless the public health emergency subsides significantly, many practices will experience dire consequences without additional financial assistance. We have attempted to provide a concise listing of such programs and resources available to assist vascular surgeons who are small businesses in accessing these opportunities.

An Updated Physician Workforce Model Predicts a Shortage of Vascular Surgeons for the Next 20 Years.

BACKGROUND: Concern regarding the adequacy of the vascular surgery workforce persists. We aimed to predict future vascular surgery workforce size and capacity using contemporary data on the US population and number, productivity, and practice patterns of vascular surgeons. METHODS: The workforce size needed to maintain current levels of access was estimated to be 1.4 vascular surgeons/100,000 population. Updated population estimates were obtained from the US Census Bureau. We calculated future vascular surgery workforce needs based on the estimated population for every 10 years from 2020 to 2050. American Medical Association Physician Masterfile data from 1997 to 2017 were used to establish the existing vascular surgery workforce size and predict future workforce size, accounting for annual rates of new certificates (increased to an average of 133/year since 2013), retirement (17%/year), and the effects of burnout, reduced work hours, transitions to nonclinical jobs, or early retirement. Based on Medical Group Management Association data that estimate median vascular surgeon productivity to be 8,481 work relative value units (wRVUs)/year, excess/deficits in wRVU capacity were calculated based on the number of anticipated practicing vascular surgeons. RESULTS: Our model predicts declining shortages of vascular surgeons through 2040, with workforce size meeting demand by 2050. In 2030, each surgeon would need to increase yearly wRVU production by 22%, and in 2040 by 8%, to accommodate the workload volume. CONCLUSIONS: Our model predicts a shortage of vascular surgeons in the coming decades, with workforce size meeting demand by 2050. Congruence between workforce and demand for services in 2050 may be related to increases in the number of trainees from integrated residencies combined with decreases in population estimates. Until then, vascular surgeons will be required to work harder to accommodate the workload. Burnout, changing practice patterns, geographic maldistribution, and expansion of health care coverage and utilization may adversely affect the ability of the future workforce to accommodate population needs.

Addition of Efficiency Measures to Current Accuracy Measures in the Vascular Laboratory Can Be Used for Future Accreditation and Payment Models.

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.

Variability in Noninvasive Vascular Laboratory Experience of Vascular Surgery Training Programs Based on Survey of Trainees Suggests the Need for a Standardized Curriculum.

BACKGROUND: Although a Registered Physician in Vascular Interpretation certification is required for vascular surgery board certification, no standardized noninvasive vascular laboratory (NIVL) curriculum for vascular surgery trainees exists. The purpose of this study is to investigate the NIVL experience of trainees and understand what helps them feel well prepared. METHODS: Current trainees in all 0 + 5 and 5 + 2 vascular surgery training programs (114) were surveyed. The most complete survey from each program was included in the analysis. Programs were divided into those in which trainees felt well prepared (WP) and those in which trainees felt unprepared (UP) for the Physician Vascular Interpretation (PVI) examination. Responses for the 2 groups were compared. RESULTS: Responses from 61 of the 114 programs (53.5%) were analyzed. Most programs devote <0.5 days per week to the NIVL (52.5%), assign lectures and textbook reading (55.7% and 47.5%), and provide hands-on experience with vascular technologists (60.7%) and attending surgeons (52.5%). Respondents from 15 programs (24.6%) took a PVI examination review course. The first-time PVI examination pass rate was 92.9% (13 of 14 trainees). The WP group reported higher rates of a structured curriculum for the NIVL (100% vs. 33.3%, P = 0.0001), one-on-one time with vascular technologists (78.6% vs. 44.4%, P = 0.05), mandatory lectures (78.6% vs. 33.3%, P = 0.004), and assigned articles (64.3% vs. 11.1%, P = 0.002). CONCLUSIONS: There is wide variation in NIVL experience among vascular surgery training programs. Many trainees feel unprepared for the PVI examination, especially those without a structured curriculum. These results suggest that a structured NIVL curriculum that includes dedicated time with vascular technologists, lectures, and articles should be established.

The Impact of Burnout on the Obstetrics and Gynecology Workforce.

Although there has been discussion of a shortage of surgical specialties including OB/GYN, consensus is difficult because of the multiple variables involved in estimating both supply and demand. In addition, burnout has become more recognized as a variable that has not been taken into account in estimating a shortage of OB/GYNs. We estimate OB/GYN physician shortages of 17%, 24%, and 31% by 2030, 2040, and 2050, respectively. Here, we examine the impact of burnout on the OB/GYN workforce. Specifically, we address the associations of burnout, reduction in clinical productivity as well as early retirement. We also discuss the implications of the substantial increase of female OB/GYNs to ∼66% of workforce over the next 10 years and how this may impact the impending OB/GYN shortage. Finally, we briefly consider possible solutions to workforce issues causing burnout.

Four-extremity venous duplex ultrasound for suspected deep venous thrombosis is an anachronism.

BACKGROUND: Duplex ultrasound is the "gold standard" for diagnosis of acute deep venous thrombosis (DVT) because of its high specificity, sensitivity, safety, and portability. However, unnecessary testing epitomizes inefficient use of scarce health care resources. Here we hypothesize that the majority of simultaneous four-extremity duplex ultrasound (FED) examinations are unnecessary. By analyzing clinical factors of patients with acute DVT found on FED, we aimed to identify a subset of high-risk patients who may have a valid indication for four-extremity testing. METHODS: We retrospectively reviewed all venous duplex ultrasound examinations performed in our Intersocietal Accreditation Commission-accredited vascular laboratory from January 1, 2009, to December 31, 2016. Patients with duplex ultrasound scans of all four limbs were included. DVT risk factors and indication for duplex ultrasound examination were recorded. The primary outcome was finding of acute DVT. RESULTS: There were 188 patients who met our search criteria, of whom 31 patients (16.5%) had acute DVT (11 upper extremity, 16 lower extremity, and 4 upper and lower extremity). Fever of unknown origin (FUO) was the main indication for requesting FED (53.7%). Patients who underwent FED for FUO had a significantly lower likelihood of DVT (odds ratio, 0.21; P = .01). DVT was rarely the proximate cause (<1% of all cases) as follow-up culture results and clinical course most often revealed other sources of fever. Only patients with an upper extremity central venous catheter (CVC; n = 103) with at least two associated risk factors had an upper extremity DVT, which was usually line associated (93%). Only patients with at least two associated risk factors had a lower extremity DVT. CONCLUSIONS: FED for FUO is inefficient, given that DVT was rarely the proximate cause of fever. Acute upper extremity DVT was found only in patients with an upper extremity CVC, demonstrating that patients without upper extremity CVC do not benefit from upper extremity duplex ultrasound examination. Upper extremity DVT is usually line associated and dependent on the number of cumulative risk factors present, suggesting that only the extremity associated with the CVC in the right clinical context should be imaged. Lower extremity DVT is also dependent on the number of cumulative risk factors present, and testing should be reserved for patients according to the clinical context. Our results indicate that a restrictive strategy can reduce testing inefficiency and health care cost without compromising patients' safety.

Ten-year reassessment of the shortage of general surgeons: Increases in graduation numbers of general surgery residents are insufficient to meet the future demand for general surgeons.

BACKGROUND: In 2008, we projected that a deficit in the general surgical workforce would grow to 19% by 2050. We reexamined population-based general surgical workforce projections to determine the impact of recent changes in population estimates and trends in certification and General Surgery Residency. METHODS: We reviewed the Census Bureau data and the potential pool of general surgeons defined by American Board of Surgery certificates, residents completing Accreditation Council for Graduate Medical Education-approved General Surgery Residency and combined American Board of Surgery and osteopathic certificates averaged from 2007-2016. The model included removal of 150 surgeons/year who subspecialize and 729 retirements/year. RESULTS: Updated census projections estimate a 2050 U.S. population of 439 million, a 19 million increase over prior census projections. From 2007-2016, the American Board of Surgery granted 10,173 certificates, averaging 1,017/year; General Surgery Residency graduations were 10,088, averaging 1,088/year; combined American Board of Surgery and osteopathic (American Osteopathic Association) certificates were 10,084, averaging 1,084/year. General surgical workforce shortage in 2050 is projected to be 7,047 (21%) based on American Board of Surgery certificates; 4,917(15%) based on General Surgery Residency completions; 5,037 (15%) based on combined American Board of Surgery and American Osteopathic Association certificates; and 57 (0%) based on hypothetical expansion of general surgeons training by 75 positions by 2021. CONCLUSIONS: Without increasing future general surgeons training numbers, the projected future general surgical workforce shortage will continue to grow.

Presence and degree of residual venous obstruction on serial duplex imaging is associated with increased risk of recurrence and progression of infrainguinal lower extremity deep venous thrombosis.

OBJECTIVE: The role of follow-up venous duplex ultrasound (DUS) after acute lower extremity deep vein thrombosis (DVT) remains unclear, yet it is commonly performed. We aimed to clarify the role of follow-up DUS. Our primary objective was to determine the association between the presence of residual venous obstruction (RVO) on DUS and DVT recurrence or propagation (rDVT). Secondary objectives included finding risk factors associated with RVO and rDVT. METHODS: We conducted a retrospective study of patients diagnosed with DVT on DUS from January 1, 2011, to December 31, 2013, that received a follow-up DUS. Patient demographics, risk factors, medications, and DUS findings were recorded. Ten segments from the common femoral to distal calf veins were checked for the presence of RVO, DVT propagation, and recurrence. RVO was defined as any nonacute venous obstruction with more than 40% of luminal diameter remaining during compression or the presence of chronic post-thrombotic occlusive disease. rDVT was measured as either a new acute DVT in the previously involved segment, or involvement of a new segment in the same extremity. RESULTS: A total of 185 lower extremities representing 156 patients met the inclusion criteria. RVO was noted in 61.1% of limbs. The 3-year rDVT rate was 10.3%. Patients with recurrent venous thromboembolism or thrombophilia had a higher risk of developing RVO (odds ratio [OR], 2.89, P < .01; OR, 4.39, P = .04, respectively). Extremities with larger clot burden had an increased risk of RVO on follow-up DUS (OR, 1.25 per segment; P < .01). The presence and degree of RVO on follow-up DUS had an increased risk of rDVT on subsequent DUS (OR, 3.90, P = .04; OR, 1.21 per segment, P = .04, respectively). Limbs with complete resolution of DVT by DUS had a significantly decreased risk of rDVT (OR, 0.26; P = .04). CONCLUSIONS: Extremities with larger initial clot burden exhibited an increased risk of subsequent RVO. The presence of RVO and, interestingly, the number of involved segments on follow-up DUS increased the risk of rDVT. Our results suggest that the presence of residual disease and increased RVO burden on follow-up DUS after an acute DVT may identify those patients who are at an increased risk for rDVT and may help guide the duration of anticoagulation therapy.

Projected Workforce of Psychiatrists in the United States: A Population Analysis.

OBJECTIVE: This analysis quantified and assessed the projected workforce of psychiatrists in the United States through 2050 on the basis of population data. METHODS: With use of data from the Association of American Medical Colleges (2000-2015), American Board of Psychiatry and Neurology (2000-2015), and U.S. Census Bureau (2000-2050), the psychiatrist workforce was projected through 2050. Two established psychiatrist-to-population ratios were used to determine the estimated demand for psychiatrists and potential shortages. RESULTS: The psychiatrist workforce will contract through 2024 to a projected low of 38,821, which is equal to a shortage of between 14,280 and 31,091 psychiatrists, depending on the psychiatrist-to-population ratio used. A slow expansion will begin in 2025. By 2050, the workforce of psychiatrists will range from a shortage of 17,705 psychiatrists to a surplus of 3,428. CONCLUSIONS: Because of steady population growth and the retirement of more than half the current workforce, the psychiatrist workforce will continue to contract through 2024 if no interventions are implemented, leading to a significant shortage of psychiatrists. Despite an expected workforce expansion beginning in 2025, it is unclear whether the shortage will completely resolve by 2050. Future research should focus on developing strategies to address this quantified shortage in an effort to curb the worsening shortage through 2024 and over the coming decades.

The impact of the aging population and incidence of cancer on future projections of general surgical workforce needs.

BACKGROUND: Assessments of the future general surgery workforce continue to project substantial shortages of general surgeons. The general surgery workforce is targeted currently to maintain a surgeon/population ratio of 6.5-7.5/100,000. METHODS: We examined population and age-associated incidence of cancer to estimate the number of general surgeons needed for initial surgical treatment of the patient with cancer in the year 2035 compared with 2010. We hypothesized that the number of general surgeons needed to provide future cancer care will exceed the projections of available general surgeons based on current training numbers, as well as on population-based ratios alone. RESULTS: The total number of new patients with cancers treated by general surgeons is projected to increase 56% (511,450 in 2010 to 798,070 in 2035). To maintain the same patient census per surgeon, it is estimated that 34,698 general surgeons will be needed. This is an increase of 9,198 over that based on current training numbers and 5,300-7,400 greater than the need projected by population growth alone. CONCLUSION: The analysis supports the hypothesis that an increasing incidence of cancer in the future will exceed the potential capacity of the general surgeon workforce. Regionalization of cancer care may be one solution to projected access issues.

Isolated Great Saphenous Vein Thrombus Is Associated with High Rates of Complications regardless of Management.

BACKGROUND: Isolated great saphenous vein thrombus (GSVT) is generally regarded as benign, and treatment is heterogeneous. Complications include thrombus propagation, new saphenous vein thrombosis, deep vein thrombosis (DVT), pulmonary embolism (PE), and symptom persistence. Our objective was to review our institution's experience with isolated GSVT to understand its natural history, the frequency of complications, real-world treatment, and the impact of proximity to the saphenofemoral junction (SFJ), on the rate of complications. METHODS: Records of patients who had lower extremity venous duplex (LEVD) demonstrating GSVT without concomitant DVT between July 2008 and June 2014 were reviewed. Demographic, medical, management, outcomes, and follow-up LEVD data were collected. RESULTS: Of 605 patients with acute GSVT, 67 limbs in 61 patients with isolated GSVT were the study group; 14.8% of patients had a hypercoagulable state, 31.1% had prior GSVT or DVT, and 23.0% of patients had malignancy; 28.4% of GSVT were observed, 13.4% were treated with aspirin/NSAIDs, and 58.2% were anticoagulated; 38.8% of limbs remained symptomatic following treatment at a mean follow-up period of 761 days; 37 limbs had GSVT <5 cm of the SFJ (group 1), and 30 had GSVT >5 cm from the SFJ (group 2). Seven patients developed PE, all in group 1 (P = 0.02). Twenty-nine limbs (43.3%) had follow-up LEVD at a mean of 23 days. In this subset, 13 patients at the initial scan (44.8%) had thrombus <5 cm of the SFJ (group 1) and 16 (55.2%) had thrombus >5 cm from the SFJ (group 2). Five limbs (17.2%) had GSVT propagation/new superficial vein thrombosis (SVT), and 6 (20.7%) developed new DVT. There was no GSVT propagation/new SVT in group 1, whereas 5 limbs (31.2%) had GSVT propagation/new SVT in group 2 (P = 0.048). DVT occurred in 2 limbs (15.3%) in group 1 and 4 limbs (25%) in group 2. CONCLUSIONS: Isolated GSVT tends to affect patients with hypercoagulable states, prior venous thromboembolism, malignancy, or recent surgery. Management is heterogeneous, and type of treatment does not seem to affect outcomes. Patients with GSVT have significant risk of persistent symptoms, recurrence, DVT, and PE. GSVT within 5 cm of the SFJ seemed to be associated with an increased rate of PE. GSVT more than 5 cm from the SFJ seemed to be associated with propagation/new SVT. Proximity to the SFJ did not impact occurrence of DVT.

Ultrasound-Guided Thrombin Injection Is a Safe and Effective Treatment for Femoral Artery Pseudoaneurysm in the Morbidly Obese.

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.
