Surgical Outcomes for Occluded Venous Thoracic Outlet Syndrome following Transaxillary First Rib Resection.

OBJECTIVE: Surgical decompression via transaxillary first rib resection (TFRR) is often performed in patients presenting with venous thoracic outlet syndrome (VTOS). We aimed to evaluate the outcomes of TFRR based on chronicity of completely occluded axillo-subclavian veins in VTOS. METHODS: We performed a retrospective institutional review of all patients who underwent TFRR for VTOS and had a completely occluded axillo-subclavian vein between 2003 to 2022. Patients were categorized into three groups based on the time of inciting VTOS event to TFRR acuity of their venous occlusion: <4 weeks, 4-12 weeks and >12 weeks. We evaluated the association of TFRR timing with one-year outcomes including patency and symptomatic improvement. We used Chi-square test to compare baseline characteristics and postoperative outcomes. RESULTS: Overall, 103 patients underwent TFRR for VTOS with a completely occluded axillo-subclavian vein (median age 30.0 years, 42.7% female, 8.8% non-White), of which 28 patients had occlusion < 4 weeks, 36 patients had occlusion 4-12 weeks, and 39 patients had occlusion >12 weeks. Postoperative venogram performed 2-3 weeks after TFRR demonstrated that 78.6% in the <4 weeks group, 72.2% in the 4-12 weeks group and 61.5% in the >12 weeks group had some degree of recanalization (p=0.76). Postoperative balloon angioplasty was successfully performed in 60 patients with stenosed/occluded axillo-subclavian vein at the time of postoperative venogram. At 10-14-month followup, 79.2% in the <4 weeks group, 73.3% in the 4-12 weeks group, and 73.3% in the >12 weeks group had patent axillo-subclavian veins based on duplex ultrasound (p=0.86). Among patients who underwent postoperative balloon angioplasty, 80.0%, 85.0% and 100% in the <4 weeks, 4-12 weeks and >12 weeks groups respectively demonstrated patency at 10-14 months (p=0.31). Symptomatic improvement was reported in 95.7% in the < 4 weeks group, 96.7% in the 4-12 weeks group and 93.5% in the >12 weeks group (P=0.84). CONCLUSION: TFRR offers excellent postoperative outcomes for symptomatic VTOS patients, even in cases of completely occluded axillo-subclavian veins, regardless of the chronicity of the occlusion. By 14 months, 95.2% of patients experienced symptomatic improvement, and 75% attained venous patency.

Risk Factors for Development of Incisional Hernia after Aortic Aneurysm Repair: Secondary Analysis of the OVER Randomized Controlled Trial.

BACKGROUND: Since the risk of mortality from rupture is elevated, elective repair of abdominal aortic aneurysms (AAAs) is often recommended. Currently, over 80% of elective repairs are carried out using an endovascular approach. While open repair has similar late survival and fewer reintervention outcomes when compared to endovascular repair, incisional hernia is a frequent complication with morbidity and cost implications. The Open versus Endovascular Repair (OVER) trial was the largest randomized trial of endovascular versus open repair of AAA in the United States. The purpose of this study was to determine risk factors associated with incisional hernia development following AAA repair via secondary analysis of the OVER data. METHODS: This was a multisite trial conducted within the Veterans Affairs health-care system. Study participants (N = 881) were enrolled from 2002 to 2008 and followed until 2011 with additional administrative data collection until 2016. Eligible patients had AAA for which elective repair was planned and randomized 1:1 to either open or endovascular repair. Incisional hernia was a prespecified end point in the OVER protocol, specifically assessed at each protocol follow-up visit. Technical details were extracted from each operative report, repair case report form(s), and adverse event form(s). Patient demographics, comorbid conditions, reported preoperative activity level, and operative details including initial approach, blood loss, and closure methods were analyzed using Bayesian hierarchical Weibull survival regression modeling. RESULTS: Incisional hernias were recorded among 46 participants (5.2%). The average time to hernia diagnosis was 3.5 years. Of the 437 participants randomized to open treatment, 427 received an open repair including crossovers from endovascular treatment assignment. Transperitoneal repair was performed in 81%, running suture in 96%, and absorbable suture in 71% of cases. Randomization to endovascular repair was associated with reduced risk of hernia (hazard ratio [HR] 0.70, 95% credible interval [CI] 0.49-0.94). Higher activity level was associated with increased hernia risk (HR 1.39, 95% CI 1.06-1.84). Approach, suture closure techniques, body mass index, diabetes, and smoking status were not associated with increased risk of hernia development. CONCLUSIONS: Incisional hernia is a frequent complication associated with open repair of abdominal aortic aneurysm and commonly required reintervention. Endovascular repair was associated with reduced risk of hernia. Patients with increased activity experienced a higher incidence of hernia. However, no other modifiable patient, operative, or technical factors were found to be associated with hernia development.

The Aging Surgeon: Considerations for Navigating a Successful and Satisfying Career.

Our careers as surgeons are some of the busiest and perhaps most sought after in existence. We have all put in countless years of tenacious effort, at times blood, frequent sweat, and occasional tears, to have the privilege to care for others and correct their ailments. Many of us are like freight trains rolling down the tracks indefinitely. But all too often we finish our training and head down those tracks without considering what stops we should make along the way, which forks in the tracks we should consider taking, and perhaps most often, we do not consider how we are going to eventually stop the train. Most of us have been witness to colleagues who keep working beyond their prime, be it for lack of alternative opportunities, lack of hobbies to retire to, or for lack of insight into their own decline. From these observations was born this presidential panel. As you can see, it is a collection of past presidents of So Cal ACS, with the exception for Dr Freischlag (who we all know would have served as president at some point had she never relocated away from Southern California). Each of these speakers has unique experience from their own careers that they will share with us so we can take pause and consider their insights and wisdom for how to navigate a successful and satisfying career.

Blue Ribbon Committee I Review: Findings and Impact.

OBJECTIVE: Review the subsequent impact of recommendations made by the 2004 American Surgical Association Blue Ribbon Committee (BRC I) Report on Surgical Education. BACKGROUND: Current leaders of the American College of Surgeons and the American Surgical Association convened an expert panel to review the impact of the BRC I report and make recommendations for future improvements in surgical education. METHODS: BRC I members reviewed the 2004 recommendations in light of the current status of surgical education. RESULTS: Some of the recommendations of BRC I have gained traction and have been implemented. There is a well-organized national curriculum and numerous educational offerings. There has been greater emphasis on preparing faculty to teach and there are ample opportunities for professional advancement as an educator. The number of residents has grown, although not at a pace to meet the country's needs either by total number or geographic distribution. The number of women in the profession has increased. There is greater awareness and attention to resident (and faculty) well-being. The anticipated radical change in the educational scheme has not been adopted. Training in surgical research still depends on the resources and interests of individual programs. Financing student and graduate medical education remains a challenge. CONCLUSIONS: The medical landscape has changed considerably since BRC I published its findings in 2005. A contemporary assessment of surgical education and training is needed to meet the future needs of the profession and our patients.

Goals, Structure and Financing of Surgical Residency Training: A Subcommittee Report of the Blue Ribbon Committee II.

OBJECTIVE: As part of the Blue Ribbon Committee II, review current goals, structure and financing of surgical training in Graduate Medical Education (GME) and recommend needed changes. SUMMARY BACKGROUND DATA: Surgical training has continually undergone major transitions with the 80-hour work week, earlier specialization (vascular, plastics and cardiovascular) and now entrustable professional activities (EPAs) as part of competency based medical education (CBME). Changes are needed to ensure the efficiencies of CBME are utilized, that stable graduate medical education funding is secured, and that support for surgeons who teach is made available. METHODS: Convened subcommittee discussions to determine needed focus for recommendations. RESULTS: Five recommendations are offered for changes to GME financing, incorporation of CBME, and support for educators, students and residents in training. CONCLUSIONS: Changes in surgical training related to CBME offer opportunity for change and innovation. Our subcommittee has laid out a potential path forward for improvements in GME funding, training structure, compensation of surgical educators, and support of students and residents in training.

The Blue Ribbon Committee II Report and Recommendations on Surgical Education and Training in the United States: 2024.

OBJECTIVE: An expert panel made recommendations to optimize surgical education and training based on the effects of contemporary challenges. BACKGROUND: The inaugural Blue Ribbon Committee (BRC I) proposed sweeping recommendations for surgical education and training in 2004. In light of those findings, a second BRC (BRC II) was convened to make recommendations to optimize surgical training considering the current landscape in medical education. METHODS: BRC II was a panel of 67 experts selected on the basis of experience and leadership in surgical education and training. It was organized into subcommittees which met virtually over the course of a year. They developed recommendations, along with the Steering Committee, based on areas of focus and then presented them to the entire BRC II. The Delphi Method was chosen to obtain consensus, defined as>80% agreement amongst the panel. Cronbach alpha was computed to assess the internal consistency of three Delphi rounds. RESULTS: Of 50 recommendations, 31 obtained consensus in the following aspects of surgical training (# consensus recommendation /# proposed): Workforce (1/5), Medical Student Education (3/8), Work Life Integration (4/6), Resident Education (5/7), Goals, Structure and Financing of Training (5/8), Education Support and Faculty Development (5/6), Research Training (7/9), and Educational Technology and Assessment (1/1). The internal consistency was good in Rounds 1 and 2 and acceptable in Round 3. CONCLUSIONS: BRC II used the Delphi approach to identify and recommend 31 priorities for surgical education in 2024. We advise establishing a multidisciplinary surgical educational group to oversee, monitor and facilitate implementation of these recommendations.

Double Trouble: Combined Neurogenic Thoracic Outlet Syndrome and Superior Labrum Anterior Posterior Tear.

Neurogenic thoracic outlet syndrome and superior labrum anterior posterior tears are usually treated in a staged manner due to different post-operative therapy needs. This case describes successful combined surgery with expedited physical therapy.

Boney abnormalities cause arterial, venous, and/or neurogenic thoracic outlet syndrome.

Background: Thoracic outlet syndrome (TOS) is a rare condition caused by compression of the neurovascular structures within the thoracic outlet. Different classifications of TOS exist depending on the neurovascular structure being compressed: neurogenic, venous, or arterial. Any of these forms can present independently or coexist with one other. TOS symptoms are sometimes precipitated by the presence of boney abnormalities that often require surgical intervention for ultimate resolution. This retrospective review will examine the presentations and outcomes of patients with TOS whose cause was a boney abnormality. Methods: A total of 73 patients who underwent thoracic outlet surgery between 2016 and 2021 were retrospectively reviewed via electronic medical records. Twelve (16%) patients demonstrated boney abnormalities on presentation causing their symptoms. The patients with boney abnormalities were analyzed based on venous, arterial, or neurogenic TOS diagnosis. Results: Of the 12 patients with boney abnormalities, 5 were classified as venous TOS, 6 patients as neurogenic TOS, and 1 as arterial TOS. The boney abnormalities were as follows: venous TOS: three clavicular fractures, one nonfused congenital clavicle, and one residual rib; neurogenic TOS: three fractured first ribs, one fractured clavicle, and two cervical ribs; and arterial TOS: fused first and second rib with bilateral cervical ribs and arterial compression. Postoperatively, there were no artery, vein, or nerve injuries. Five patients had a pneumothorax treated over night with a chest tube, and one patient had a superficial wound infection. The median hospital stay was 1 day. All patients completed physical therapy after surgery. All patients have symptom resolution at follow-up. Conclusions: Patients with boney abnormalities constitute about one-fifth of patients who can present with all three forms of TOS: neurogenic, arterial, and venous, and some will have more than one of these presentations. Results in patients undergoing surgery with boney abnormalities causing thoracic outlet syndrome are excellent with symptom resolution and without substantial complications.

Translating the Value of the Academic Surgeon Into Salary, Time, and Resources.

Academic surgeons provide tremendous value to institutions including notoriety, publicity, cutting-edge clinical advances, extramural funding, and academic growth and development. In turn, these attributes may result in improved reputation scores and hospital or medical center rankings. While many hospital systems, schools of medicine, and departments of surgery claim to have a major commitment to academic surgery and research, academic surgeons are often undercompensated compared to clinically focused counterparts. Existing salary benchmarks (e.g., the Medical Group Management Association (MGMA) or the Association of American Medical Colleges (AAMC)) are often used but are imperfect. Thus, the value proposition for academic surgeons goes beyond compensation and often includes protected time for academic pursuit, nonsalary financial support, and other intangible benefits to being associated with a major academic center (e.g., abundance of scientific collaborators, infrastructure for grant management). As a result, institution-specific practices have developed and academic surgeons are left to negotiate salary support including bonus structures, protected time, and recruitment packages on a case-by-case basis without a clear roadmap. A diverse panel representing a range of academic surgical experiences was convened at the 2022 Academic Surgical Congress to illuminate this complex, often stress-inducing, aspect of an academic surgeon's professional career.

Delay in Diagnosis for Two Patients With McCleery Syndrome.

McCleery syndrome is a rare form of venous thoracic outlet syndrome characterized by intermittent obstruction of the subclavian vein (SCV) without thrombosis. In 2022, two patients presented to our clinic with McCleery syndrome after living with venous symptoms for over one year. Duplex scans of both patients revealed compression of the SCV on abduction. A first rib resection and anterior scalenectomy were performed to decompress the SCV. At two weeks post-op, a follow-up venogram revealed widely patent, unobstructed SCVs in both patients.

Anterior Scalene Anomaly in a Patient With Arterial and Neurogenic Thoracic Outlet Syndrome.

Compression of the neurovascular structures of the upper extremity as they pass through the thoracic outlet result in thoracic outlet syndrome. The myriad of symptoms associated with the syndrome vary based on the structure(s) compressed: the subclavian artery/vein or the inferior trunk of the brachial plexus. This is a common site of compression especially in the presence of upper extremity injury, overuse or anatomical abnormalities. Majority of patients present with neurogenic pain and weakness; herein, we present the case of a patient with symptoms of both arterial and neurogenic compression caused by aberrant anterior scalene anatomy. These patients are excellent surgical candidates for first rib resection and anterior scalenectomy. A transaxillary approach offers the clinician an adequate window to identify anatomical abnormalities intraoperatively and safely excise the first rib and anterior scalene muscle.

Trends in Surgeon Burnout in the US and Canada: Systematic Review and Meta-Regression Analysis.

BACKGROUND: Burnout among surgeons is increasingly recognized as a crisis. However, little is known about changes in burnout prevalence over time. We evaluated temporal trends in burnout among surgeons and surgical trainees of all specialties in the US and Canada. STUDY DESIGN: We systematically reviewed MEDLINE, Embase, and PsycINFO for studies assessing surgeon burnout from January 1981 through September 2021. Changes in dichotomized Maslach Burnout Inventory scores and mean subscale scores over time were assessed using multivariable random-effects meta-regression. RESULTS: Of 3,575 studies screened, 103 studies representing 63,587 individuals met inclusion criteria. Publication dates ranged from 1996 through 2021. Overall, 41% of surgeons met criteria for burnout. Trainees were more affected than attending surgeons (46% vs 36%, p = 0.012). Prevalence remained stable over the study period (-4.8% per decade, 95% CI -13.2% to 3.5%). Mean scores for emotional exhaustion declined and depersonalization declined over time (-4.1 per decade, 95% CI -7.4 to -0.8 and -1.4 per decade, 95% CI -3.0 to -0.2). Personal accomplishment scores remained unchanged. A high degree of heterogeneity was noted in all analyses despite adjustment for training status, specialty, practice setting, and study quality. CONCLUSIONS: Contrary to popular perceptions, we found no evidence of rising surgeon burnout in published literature. Rather, emotional exhaustion and depersonalization may be decreasing. Nonetheless, burnout levels remain unacceptably high, indicating a need for meaningful interventions across training levels and specialties. Future research should be deliberately designed to support longitudinal integration through prospective meta-regression to facilitate monitoring of trends in surgeon burnout.

Effect of preservation of antegrade hypogastric flow on development of claudication following aortoiliac aneurysm repair.

OBJECTIVE: The objective of this study was to compare the rate of development of buttock claudication in patients undergoing aortoiliac aneurysm repair with and without exclusion of antegrade hypogastric arterial flow. In the absence of convincing data, questions remain regarding the best management of hypogastric arterial flow to prevent the theoretical risk of buttock claudication. METHODS: The Veterans' Affairs Open Versus Endovascular Repair (OVER) Cooperative Study prospectively collected information on buttock claudication. Trial participants were specifically prompted both pre- and postoperatively to report the development of claudication symptoms at several anatomic levels. Of note, trial investigators were specifically trained to occlude the trunk hypogastric arterial, preserving the anterior and posterior divisions. Bayesian survival models were created to evaluate time to development of left, right, or bilateral buttock claudication according to the presence/absence of antegrade hypogastric perfusion. RESULTS: A total of 881 patients from the OVER trial with information regarding status of hypogastric flow were included in the analysis. Of these, 788 patients maintained bilateral antegrade hypogastric arterial perfusion, 63 had right hypogastric coverage/occlusion, and 27 had left hypogastric coverage/occlusion, whereas 3 patients had bilateral hypogastric coverage/occlusion. Just under 5% of all patients (n = 41) developed buttock claudication. After adjustment for smoking, chronic obstructive pulmonary disease, medications, study arm, preoperative activity level, body mass index, age, and diabetes, intervention-related changes to hypogastric perfusion had no effect on time to development of buttock claudication. A Maximum A Posteriori Kullback- Leibler misfit χ2 was 14.45 with 24 degrees of freedom, resulting in a goodness of fit P-value of P = .94, indicative of a good fit. CONCLUSIONS: OVER is the largest aneurysm treatment study to prospectively collect data related to the development of claudication as well as hypogastric preservation status. Despite this, we were unable to find evidence to support the assertion that preservation of antegrade hypogastric flow decreases the rate of development of buttock claudication symptoms. The low rate of development of buttock claudication overall and in the subgroups is striking.
