RESUMEN

BACKGROUND: Post-traumatic stress disorder (PTSD) has been shown to be more common in surgical residents than the general population. This may be due to the rigors of a surgical residency. This study aims to compare the prevalence of screening positive for PTSD (PTSD+) among 7 medical specialties. Further, we intend to identify independent risk factors for the development of PTSD. METHODS: A cross-sectional national survey of residents (n = 1904) was conducted from September 2016 to May 2017. Residents were screened for PTSD. Traumatic stressors were identified in those who reported symptoms of PTSD. Potential risk factors for PTSD were assessed using multivariate regression analysis with stepwise backward elimination against 30 demographic, occupational, psychological, work-life balance, and work-environment variables. RESULTS: Residents from anesthesiology (n = 180), emergency medicine (n = 222), internal medicine (n = 473), general surgery (n = 464), obstetrics and gynecology (n = 226), psychiatry (n = 208), and surgical subspecialties (n = 131) were surveyed. No statistical difference was found in the prevalence of PTSD between specialties. Prevalence ranged from 14% to 23%. Eight independent risk factors for the development of PTSD+ were identified: higher postgraduate year, female gender, public embarrassment, emotional exhaustion, feeling unhealthy, job dissatisfaction, hostile hospital culture, and unsafe patient load. CONCLUSIONS: The prevalence of PTSD in surgery residents was not statistically different when compared to those in other medical specialties. However, the overall prevalence of PTSD (20%) remains more than 3 times that of the general population. Overall, 8 risk factors for PTSD were identified. These risk factors varied by specialty. This may highlight the unique challenges of training in each discipline. Specialty specific interventions to improve resident wellness should be emphasized in the development of our young physicians.

RESUMEN

We aim to investigate the prevalence of posttraumatic stress disorder (PTSD), physician burnout (PBO), and work-life balance (WLB) among surgical residents, fellows, and attendings to illustrate the trends in surgeon wellness. A cross-sectional national survey of surgical residents, fellows, and attendings was conducted screening for PTSD, PBO, and WLB. The prevalence of screening positive for PTSD was more than two times that of the general population at all levels of experience, and more than half have an unhealthy WLB. The prevalence of PTSD, PBO, and unhealthy WLB declined with increasing level of experience (P < 0.001). One deviation in this trend was a lower prevalence of PBO among surgical fellows compared with residents and attendings (P < 0.001). Surgeon wellness improved with increasing level of experience. The incorporation of wellness programs into surgical residencies is essential to the professional development of young surgeons to cultivate healthy lasting habits for a well-balanced career and life.

RESUMEN

BACKGROUND: Open abdominal aortic surgery is among procedures with high morbidity and mortality. Adverse postoperative complications may be more common in morbidly obese patients. OBJECTIVES: This study compared the outcomes of open abdominal aortic surgeries in patients with and without morbid obesity. SETTING: A retrospective analysis of 2007-2014 Healthcare Cost and Utilization Project-Nationwide Inpatient Sample. METHODS: We included patients who underwent open abdominal aortic aneurysm (AAA) repair or open aorta-iliac-femoral (AIF) bypass. Demographic factors, morbid obesity, co-morbidities, and emergent versus elective surgery were considered for univariate and multivariate analyses. RESULTS: A total of 29,340 patients (13,443 AAA repair and 15,897 AIF bypass) were included (age 66.3 ± 10.8 years, 65.7% male). The mortality was 9.1% in 536 patients with morbid obesity compared with 7.1% in patients without morbid obesity. Based on multivariate analysis, age, existing co-morbidities, emergent versus elective setting, and morbid obesity were found to be independent predictors of mortality. Patients with morbid obesity had an odds ratio of 3.61 (95% CI, 1.50-8.68; P = .004) for mortality, longer mean length of stay (11.2 versus 9.3 days, P < .001), and higher total hospital charges ($99,500 versus $73,700, P < .001). CONCLUSIONS: Morbid obesity is an independent risk factor of mortality in patients undergoing open AAA repair and AIF bypass. Weight loss strategies should be considered for morbidly obese patients with an anticipation of open abdominal aortic procedures.

RESUMEN

Posttraumatic stress disorder (PTSD) among trauma surgeons is three times that of the general population, and physician burnout (PBO) among surgeons is rising. Given that PTSD and PBO are both stress-based syndromes, we aim to identify the prevalence and risk factors for PTSD among trauma and nontrauma surgeons, and determine if a relationship exists. A cross-sectional survey of surgeons was conducted between September 2016 and May 2017. Respondents were screened for PTSD and PBO. Traumatic stressors were identified, and 20 potential risk factors were assessed. The respondents (n = 1026) were grouped into trauma (n = 350) and nontrauma (n = 676). Between the cohorts, there was no significant difference in prevalence of screening positive for PTSD (17% vs 15%) or PBO (30% vs 25%). A relationship was found between PTSD and PBO (P < 0.001). The most common traumatic stressor was overwhelming work responsibilities. Potential risk factors for PTSD differed, but overlapping risk factors included hospital culture, hospital support, and salary (P < 0.05). Our findings of an association between PTSD and PBO is concerning. Interventions to reduce rates of PTSD should target changing the existing culture of surgery, improving hospital support, and ensuring equitable pay.

RESUMEN

INTRODUCTION: A physician shortage is on the horizon, and surgeons are particularly vulnerable due to attrition. Reduced job satisfaction leads to increased job turnover and earlier retirement. The purpose of this study is to delineate the risk factors that contribute to reduced job satisfaction. METHODS: A cross-sectional survey of US surgeons was conducted from September 2016 to May 2017. Screening for job satisfaction was performed using the abridged Job in General scale. Respondents were grouped into more and less satisfied using the median split. Twenty-five potential risk factors were examined that included demographic, occupational, psychological, wellness, and work-environment variables. RESULTS: Overall, 993 respondents were grouped into more satisfied (n = 502) and less satisfied (n = 491) cohorts. Of the demographic variables, female gender and younger age were associated with decreased job satisfaction (p = 0.003 and p = 0.008). Most occupational variables (specialty, experience, academics, practice size, payment model) were not significant. However, increased average hours worked correlated with less satisfaction (p = 0.008). Posttraumatic stress disorder, burnout, wellness, all eight work-environment variables, and unhappiness with career choice were linked to reduced job satisfaction (p = 0.001). CONCLUSION: A surgeon shortage has serious implications for health care. Job satisfaction is associated with physician retention. Our results suggest women and younger surgeons may be at increased risk for job dissatisfaction. Targeted work-environment interventions to reduce work-hours, improve hospital culture, and provide adequate financial reimbursement may promote job satisfaction and wellness.

RESUMEN

BACKGROUND: We aim to evaluate the prevalence of PTSD, its association with physician burnout, and risk factors for PTSD among surgical residents. METHODS: A cross-sectional national survey of surgical residents was conducted screening for PTSD. Causative traumatic stressors were queried, and thirty-one potential risk factors for PTSD were evaluated. RESULTS: A positive PTSD screen (PTSD+) was found in 22% of 582 surgical residents, and an additional 35% were "at risk" for PTSD. Traumatic experiences occurred most commonly as a PGY1, and the most common stressor was bullying. An increase in average hours of work per week (p < 0.001), a high-risk screen for PBO (p < 0.001), and feeling unhealthy (p = 0.001) were associated with an increasing prevalence of screening PTSD+. CONCLUSIONS: The prevalence of screening PTSD+ among surgical residents (22%) was more than three times the general population. Increased work-hours, a high-risk PBO screen, and reduced resident wellness were associated with screening PTSD+.

RESUMEN

BACKGROUND: The aim of the study was to investigate the clinical results of laser atherectomy in the treatment of peripheral arterial disease. METHODS: Retrospective analysis of consecutive patients underwent laser atherectomy at a single institution during a 7-year period by vascular surgeons and interventional cardiologists in a tertiary university-affiliated hospital. Clinical data were retrieved from patient charts and hospital electronic medical records along with the associated arteriograms. RESULTS: A total of 461 lesions in 343 limbs were treated in 300 patients with a mean age of 70 years. The indication was critical limb ischemia (CLI) with rest pain or tissue loss in 227 (66%) of interventions and claudication in 116 (34%). All procedures included an associated balloon angioplasty, while stenting was performed in 33%. Technical success was achieved in 99% with only 2 (<1%) cases with an acute procedure-related complication requiring surgical intervention. At a mean follow-up of 28 months (range, 1-87 months; median 24 months), 156 patients (45%) became asymptomatic or achieved significant clinical improvement (resolution of tissue loss or rest pain), 60 (17%) remained with CLI, 30 (9%) had a major proximal amputation, and 18 (5%) had a minor amputation. Freedom from major amputation was 90% at 5 years by life-table analysis. Univariate statistical analysis demonstrated the risk of a major amputation to be associated with diabetes, hemodialysis, and tissue loss (P < 0.05 to P < 0.005), while multivariate logistic regression analysis indicated diabetes to be overwhelmingly important (RR: 4.84; 95% confidence interval [CI]: 1.1-21.3; P < 0.05). In a similar manner, multivariate analysis indicated dialysis (RR: 2.46; 95% CI: 1.01-5.98; P < 0.05) and CLI (RR: 2.27; 95% CI: 1.42-3.65; P < 0.01) were associated with higher likelihood for lack of clinical improvement. There was no difference in major amputation rates between surgeons and interventional cardiologists (RR: 1.5; 95% CI: 0.7-2.1; P < 0.1) although it was 3 times more likely for the patients treated by surgeons to suffer from CLI (odds ratio: 3.2; 95% CI: 1.9-5.4; P < 0.0001). CONCLUSIONS: Laser atherectomy is a safe and useful adjunct in limb salvage. Diabetics have much higher probability of requiring a proximal amputation, while those on dialysis and with CLI are least likely to gain clinical benefit.

RESUMEN

A 56-year-old woman presented with episodic vertigo, dizziness, and diplopia during meals and prolonged verbal presentations at work. Subsequent work-up included an eventual catheter-based angiogram revealing an ostial left external carotid artery (ECA) occlusion with reconstituted retrograde flow via a variant collateral branch from the dominant left vertebral artery. The findings demonstrate that repetitive activities involving craniofacial muscular systems supplied by the ECA result in a symptomatic arterial steal syndrome via the enhanced diverted flow from the collateral vertebral-basilar arterial system. A left ECA endarterectomy with reimplantation of the vessel was performed, and the patient has been episode free thereafter.

RESUMEN

PURPOSE: Central venous obstruction Occlusion (CVO) has been considered a contraindication for creating a vascular access due to fear of developing a swollen extremity. However, many of these individuals developed large collateral veins and are asymptomatic. We report our experience constructing arteriovenous fistulas (AVFs) in these challenging patients. METHODS: Patients with a new AVF constructed in the presence of known CVO were identified. Venous imaging confirmed proximal obstruction and extensive collateral venous return. The AVF was constructed in the extremity with the most favorable ultrasound vessel mapping and collateral central venous outflow. Arterial inflow via the radial artery was utilized when feasible. RESULTS: AVFs associated with known CVO were constructed in 19 patients during an eight-year time period. The mean age was 53 years, 63% were female, and 58% diabetic. Arterial inflow was from the radial artery in 15 patients and the brachial or axillary artery in 5 individuals. Post-operative AVF flow volumes were 415-910 mL/min (mean = 640 mL/min). Eight patients (42%) developed some degree of arm edema. Two resolved without intervention. The others required inflow banding (n = 2), outflow branch coiling (n = 1), and/or recanalization with angioplasty (n = 4) of the CVO to resolve swelling. Mean follow-up was 14 months. Two AVFs failed at 8 and 16 months. Primary and cumulative patency rates were 49% and 100% at 12 months and 39% and 80% at 24 months, respectively. CONCLUSIONS: CVO need not preclude the creation of a successful AVF. Extensive venous collaterals and avoiding high-flow AVFs are important elements for success. Cumulative patency was 80% at 24 months.

RESUMEN

BACKGROUND: Observation versus ligation of a functional arteriovenous fistula (AVF) after successful renal transplantation (SRT) has been a controversial topic of debate. Congestive heart failure and pulmonary hypertension are common in dialysis patients, and more frequent when vascular access flow is excessive. Renal transplant failure may occur in up to 34% of patients after 5 years, therefore maintaining a moderate flow AVF appears warranted. We review SRT patients with high flow-AVFs (HF-AVF) and clinical signs of heart failure where a modified precision banding procedure was used for access flow reduction. METHODS: Patients referred for HF-AVF evaluation after SRT were identified and records reviewed retrospectively. In addition to recording clinical signs of heart failure, each patient had ultrasound AVF flow measurement before and after temporary AVF occlusion of the access by digital compression. Pulse rate and the presence or absence of a cardiac murmur was noted before and after AVF compression. Adequacy of access flow restriction was evaluated intraoperatively using ultrasound flow measurements, adjusting the banding diameter in 0.5 mm increments to achieve the targeted AVF flow. RESULTS: Twelve patients were evaluated over a 19-month period. Eight (66%) were male and one (8%) obese. Ages were 15-73 years (mean = 42). The AVFs were established 24-86 months previously. The mean pulse rate declined after AVF compression from 90/min to 72/min (range 110-78). Six patients had a precompression cardiac flow murmur that disappeared with temporary AVF compression. One patient with poor cardiac function underwent immediate AVF ligation with dramatic improvement in cardiac status. All other patients underwent a precision banding procedure with real-time flow monitoring. Mean access flow was 2,280 mL/min (1,148-3,320 mL/min) before access banding and was 598 mL/min (481-876) after flow reduction. The clinical signs of heart failure disappeared in all patients. All AVFs remained patent although one individual later requested ligation for cosmesis. Two patients had renal transplant failure and later successfully used the AVF. Follow-up postbanding was 1-18 months (mean = 12). CONCLUSIONS: Patients with successful renal transplants and HF-AVFs had resolution of heart failure findings and maintenance of access patency using a modified precision banding procedure. Flow reduction in symptomatic renal transplant patients with elevated access flow is recommended. Further study is warranted to substantiate these recommendations and clarify the appropriate thresholds for such interventions.

RESUMEN

Primary subclavian vein stents are not recommended for venous thoracic outlet syndrome before surgical decompression by first rib resection due to a high risk of fracture because they are compressed between the clavicle and first rib. After rib removal, however, stent insertion has been advocated for venous restenosis, and it is felt that stent fracture is unlikely to occur. We present a case suggesting that repetitive differential vein movement during respiration may be one of the causative factors for stent fractures occurring in this anatomic region.

RESUMEN

BACKGROUND: Compression stockings are commonly prescribed by physicians for lower extremity edema and venous insufficiency. However, no data are available for clinicians to assess the relative quality of various brands, particularly low-cost generics now available directly to consumers through the Internet. We examined the actual compression provided by gradient stockings from multiple manufacturers. METHODS: A total of 36 class 2 (20-30 mm Hg) men's medium-sized below-knee compression stockings from six different manufacturers (n = 6 of each brand) with approximately the same quality and materials were chosen to be studied. Identifying brand names were removed, and they were randomly and blindly tested by a technician in accordance with accepted industry standards. A calibrated constant rate of extension tensile instrument (Zwick Z010; Zwick Roell, Ulm, Germany) was used, and the tension generated by the stockings at the ankle and calf was measured using minimum, average, and maximum circumference sizes. All measurements were performed in duplicate. RESULTS: The compression pressures generated by the stockings were almost all within the stated range of 20 to 30 mm Hg at the ankle, but all except one were below 20 mm Hg at the calf. There were also significant differences between manufacturers at both the ankle and the calf (P < .0001). The expected pressure reduction between the two locations varied, but one stocking had only a minimal 2 mm Hg (8%) gradient, which was significantly less than all of the other tested brands and below the recommended 20% to 50% reduction. Cost analysis demonstrated that the discount brands were significantly lower in price but provided absolute compression and pressure gradients similar to those of the more expensive brands. CONCLUSIONS: There is significant variability among stockings, both in the absolute pressures and in the pressure gradients generated from the ankle to the calf, thought to be functionally important for venous flow. The cheaper stockings offered the same degree of compression and pressure gradient as the more expensive brands. These results suggest the need for manufacturing standards in the United States and a revision in labeling requirements to mandate more accurate and complete pressure disclosures.

RESUMEN

Aortic injury after thoracic spinal instrumentation is a rare complication that carries significant potential morbidity and mortality if it is not appropriately managed. We report a patient successfully treated in an endovascular manner, thereby applying minimally invasive techniques to avoid the morbidity of open thoracotomy. Decreased short-term morbidity with the endovascular approach offers significant advantage over open repair, thereby omitting aortic cross-clamping, thoracotomy, and increased risk from the patient's comorbidities. An endovascular approach to this potentially devastating complication of thoracic spinal instrumentation can be both safe and effective in selected patients and not exclusively performed in cases of hemorrhage, hematoma, or pseudoaneurysm.

RESUMEN

BACKGROUND: Avoiding dialysis access-associated ischemic steal syndrome (DASS) in patients with upper extremity peripheral vascular occlusive disease while creating a functional hemodialysis vascular access may be challenging. We constructed an autogenous access with primary proximalization of the arterial inflow to prevent hand ischemia in patients at high risk for this complication. METHODS: Patients requiring hemodialysis access with physical findings suggesting a high risk of access-related hand ischemia (absent radial, ulnar, and brachial palpable pulses associated with small calcified vessels by ultrasound examination) underwent a primary arteriovenous fistula transposition procedure utilizing the axillary artery for inflow. The arteriovenous fistula was either a reversed flow basilic vein transposition supplemented by valvulotomy (n = 22); a translocated reversed basilic vein (n = 4); a cephalic vein harvested into the forearm and placed in a loop configuration for axillary artery inflow (n = 3); or a translocated reversed saphenous vein (n = 1). RESULTS: Thirty patients with a mean age of 60 years (range, 31-83 years) underwent successful primary axillary artery inflow procedures during a 3-year period. Of these, 23 (77%) were female and 25 (83%) were diabetic. Twenty-one (70%) had previous vascular access procedures and 10 (33%) were obese. No patient developed postoperative ischemia. Three individuals died 2, 14, and 19 months following surgery, none related to vascular access. Three accesses failed after 1, 5, and 7 months and could not be salvaged. Life-table primary, primary assisted, and cumulative patency rates were 57%, 78%, and 87% respectively at 1 year with a mean follow-up of 7 months (range, 1-25 months). Cephalic vein outflow was associated with fewer access failures, fewer interventions postoperatively, and lower rates of arm swelling (P < .01). CONCLUSIONS: Creating a basilic vein transposition for vascular access utilizing axillary artery inflow is a good option for patients with severe peripheral vascular disease. It offers a high patency rate and the prevention of DASS. Retrograde basilic vein outflow through the median cubital and cephalic vein is associated with the best outcome and is the recommended configuration.

RESUMEN

An autogenous arteriovenous hemodialysis access (AVF) remains the consensus-recommended vascular access for individuals requiring hemodialysis. Surgical options, strategies, and guidelines have been established by several organizations, including the National Kidney Foundation, the Fistula First Breakthrough Initiative, and the Society for Vascular Surgery. Establishing a successful AVF in a high percentage of patients requires a thorough knowledge of the many access options and clinical practice recommendations, in addition to a careful clinical history/physical examination, pre- and postoperative ultrasound, and further vascular imaging in select patients. The more common AVF configurations may not be possible in complex patients because of limited venous outflow, arterial insufficiency, or both. However, the vascular access surgeon may still be able to construct a successful AVF in these challenging patients by utilizing one of several alternative procedures. Avoiding prosthetic arteriovenous accesses and central venous catheter-based dialysis is feasible in most patients.

RESUMEN

OBJECTIVE: Arteriovenous fistulas (AVFs) are the preferred choice for hemodialysis vascular access (AV access); however, there is debate over the utility of AVFs in older patients, particularly concerning access maturation and functionality. We reviewed our AV access experience in patients ≥65 years of age. METHODS: We analyzed consecutive AV access patients ≥65 years old with access operations between March 2003 and December 2009. All patients had ultrasound vessel mapping. In addition to overall outcomes review, the data for patients ≥65 years old were stratified into three 10-year increments by age for further analysis. We compared functional patency data for our older patients with those of our non-elderly patients aged 21 to 64 years treated during the same time period. RESULTS: Four hundred sixty-one consecutive AV access patients new to our practice were included in this study. Ages were 65 to 94 years (mean, 73 years). Two hundred thirty-six (51.2%) were female, 276 (59.9%) patients were diabetic, and 103 (22.3%) were obese. One hundred seven (23.2%) patients had previous access operations. Radiocephalic AVFs were constructed in 29 (6.3%) patients, 99 (21.5%) patients had brachial artery inflow AVFs, 330 (71.6%) had proximal radial artery AVFs, and three were based on the femoral artery. Transposition AVFs were used in 124 (26.9%) patients. No grafts were used for AV access in any patient during the study period. Time to AVF use was 0.5 to 6 months (mean, 1.5 months). Primary, primary assisted, and cumulative patency for patients aged 65 to 94 years were 59.9%, 93.7%, and 96.9% at 12 months and 45.3%, 90.1%, and 94.6% at 24 months, respectively. Follow-up was 1.5 to 77 months (mean, 17.0 months). Subgroup age stratification (65-74 [n = 268], 75-84 [n = 167], 85-94 [n = 26] years) found no statistical difference in functional access outcomes. Primary, primary assisted, and cumulative patency rates were not statistically different in the elderly and non-elderly populations (P = .29, .27, and .37, respectively). One hundred fifty-six patients died during the study period, 1.3 to 61 months (mean, 20 months) after access creation. No deaths were related to access operations. CONCLUSIONS: AVFs are feasible and offer functional and timely AV access in older patients. There was no difference in functional access outcomes for older patients with subgroup age stratification. AVF patency rates were not statistically different in the elderly and non-elderly populations. Cumulative AVF patency for patients ≥65 years of age was 96.9% at 12 months and 94.6% at 24 months.

RESUMEN

BACKGROUND: Arteriovenous fistula are created less frequently in obese individuals, and fewer of these access procedures become functional. The authors review their experience with the excision of subcutaneous tissue (lipectomy) overlying upper arm cephalic vein arteriovenous fistulas in obese patients. METHODS: Consecutive vascular access patients undergoing lipectomies for difficult access cannulation due to vein depth were reviewed. Cephalic vein depth was measured by ultrasound at 3 sites before lipectomy and again before the first cannulation. RESULTS: Thirty patients were reviewed, with a mean body mass index of 40.2 kg/m² (range, 28-57.7 kg/m²). The mean age was 52 years. Seventeen patients were women, and 19 had diabetes. The mean preoperative vein depth of 15.8 mm (range, 6-30 mm) was reduced to 4.1 mm (range, 3-8 mm) (P ≤ .01). All fistulas were functional, and only 1 failed during a follow-up period of 2.2 to 53.2 months. CONCLUSIONS: Lipectomy offers a relatively simple and successful method of extending direct autogenous vascular access to obese individuals.

RESUMEN

Dialysis associated steal syndrome (DASS) is relatively uncommon but constitutes a serious risk for patients undergoing vascular access operations. We report two patients with DASS where brachial artery vascular access inflow was revised to the proximal radial artery for arteriovenous fistula (AVF) inflow. DASS was resolved in both patients with the permanent resolution of symptoms, in addition to the healing of ulcerations and ischemia. Both AVFs were immediately functional and durable.
