RESUMEN
Descriptive studies regarding how to integrate diversity, equity, and inclusion (DEI) into medical education are lacking. We utilized the AAMC's Key Steps for Assessing Institutional Culture and Climate framework to evaluate our current curriculum via listening tours (n = 34 participants) and a survey of the 10 pre-clinical block directors, to better understand the opportunities and challenges of improving DEI in the pre-clinical curriculum. Opportunities included diversifying cases and standardized patients, enhancing information on systemic racism and social determinants of health, and increasing racial humility and population genetics/epigenetics training. Faculty had issues with "correct ways" to incorporate DEI and time constraints. Supplementary Information: The online version contains supplementary material available at 10.1007/s40670-023-01924-7.
RESUMEN
Vitamin C levels are known rapidly decrease in adult critical illness. Vitamin C scavenges free radicals, provides critical protection of the endothelial barrier, and improves endothelial responsiveness to catecholamines. Children with congenital heart disease and undergoing cardiac surgery might be at increased risk for low circulating vitamin C levels. A prospective single-center observational study investigated perioperative changes in vitamin C levels in critically ill Children who underwent congenital heart surgery using CPB. Vitamin C serum levels were collected preoperatively and postoperatively (upon admission to the ICU, 24 and 72 h). Linear mixed-effect model was used to estimate mean circulating concentration of vitamin C and to estimate changes in concentration over time. Primary outcome was change in circulating levels of vitamin C before and after CPB. Secondary outcomes were hospital length of stay (LOS), acute kidney injury (AKI), and illness severity. Forty-one patients with a median age of 4.5 [interquartile range (IQR) 2.6-65.6] months at the time of surgery were consented and enrolled. Median CPB duration was 130 [90-175] minutes, and hospital LOS was 9.1 [5.2-19] days. Mean vitamin C levels (µmol/L) before CPB, at PICU admission, 24 h, and 72 h were 82.0 (95% CI 73.4-90.7), 53.4 (95% CI 44.6,62.0), 55.1 (95% CI 46.3,63.8), and 59.2 (95% CI 50.3,68.1), respectively. Upon postoperative admission to the PICU, vitamin C levels decreased by 28.7 (95% CI 20.6-36.8; p < 0.001) µmol/L, whereas levels at 24 and 72 h recovered and did not differ substantially from concentrations reported upon PICU admission (p > 0.15). Changes in vitamin C concentration were not associated with CPB time, STAT mortality category, age, or PIM3. Three patients had post-CPB hypovitaminosis C or vitamin C deficiency. Reduction in vitamin C levels was not associated with hospital LOS (p = 0.673). A 25 µmol/L decrease in vitamin C levels upon PICU admission was associated with developing AKI (aOR = 3.65; 95% CI 1.01-18.0, p = 0.049). Pediatric patients undergoing cardiac surgery with CPB showed decreased vitamin C levels during the immediate postoperative period. Effects of hypovitaminosis C and vitamin C deficiency in this population remain unclear.

BACKGROUND: Mailed fecal immunochemical testing (FIT) programs are increasingly utilized for population-based colorectal cancer (CRC) screening. Advanced notifications (primers) are one behavioral designed feature of many mailed FIT programs, but few have tested this feature among Veterans. OBJECTIVE: To determine if an advanced notification, a primer postcard, increases completion of FIT among Veterans. DESIGN: This is a prospective, randomized quality improvement trial to evaluate a postcard primer prior to a mailed FIT versus mailed FIT alone. PARTICIPANTS: A total of 2404 Veterans enrolled for care at a large VA site that were due for average-risk CRC screening. INTERVENTION: A written postcard sent 2 weeks in advance of a mailed FIT kit that contained information on CRC screening and completing a FIT. MAIN MEASURES: Our primary outcome was FIT completion at 90 days, and our secondary outcome was FIT completion at 180 days. KEY RESULTS: Overall, unadjusted mailed FIT return rates were similar among control vs. primer arms at 90 days (27% vs. 29%, p = 0.11). Our adjusted analysis found a primer postcard did not increase FIT completion compared to mailed FIT alone (OR 1.14 (0.94, 1.37)). CONCLUSIONS: Though primers are often a standard part of mailed FIT programs, we did not find an increase in FIT completion with mailed postcard primers among Veterans. Given the overall low mailed FIT return rates, testing different ways to improve return rates is essential to improving CRC screening.

PURPOSE: To state the position of the Society of Interventional Radiology (SIR) on the endovascular management of chronic iliofemoral venous obstruction with metallic stents. MATERIALS AND METHODS: A multidisciplinary writing group with expertise in treating venous disease was convened by SIR. A comprehensive literature search was conducted to identify studies on the topic of interest. Recommendations were drafted and graded according to the updated SIR evidence grading system. A modified Delphi technique was used to achieve consensus agreement on the recommendation statements. RESULTS: A total of 41 studies, including randomized trials, systematic reviews and meta-analyses, prospective single-arm studies, and retrospective studies were identified. The expert writing group developed 15 recommendations on the use of endovascular stent placement. CONCLUSIONS: SIR considers the use of endovascular stent placement for chronic iliofemoral venous obstruction to be likely to help selected patients, but the risks and benefits have not been fully quantified in well-designed randomized studies. SIR recommends urgent completion of such studies. In the meantime, careful patient selection and optimization of conservative therapy are recommended prior to stent placement, with attention to appropriate stent sizing and quality procedural technique. The use of multiplanar venography with intravascular ultrasound is suggested in diagnosing and characterizing obstructive iliac vein lesions and in guiding stent therapy. After stent placement, SIR recommends close patient follow-up to ensure optimal antithrombotic therapy, durable symptom response, and early identification of adverse events.

PURPOSE: To establish the updated position of the Society of Interventional Radiology (SIR) on the endovascular management of acute iliofemoral deep vein thrombosis (DVT). MATERIALS AND METHODS: A multidisciplinary writing group with expertise in treating venous diseases was convened by SIR. A comprehensive literature search was conducted to identify studies on the topic of interest. Recommendations were drafted and graded according to the updated SIR evidence grading system. A modified Delphi technique was used to achieve consensus agreement on the recommendation statements. RESULTS: A total of 84 studies, including randomized trials, systematic reviews and meta-analyses, prospective single-arm studies, and retrospective studies were identified and included in the review. The expert writing group developed 17 recommendations that pertain to the care of patients with acute iliofemoral DVT with the use of endovascular venous interventions. CONCLUSIONS: SIR considers endovascular thrombus removal to be an acceptable treatment option in selected patients with acute iliofemoral DVT. Careful individualized risk assessment, high-quality general DVT care, and close monitoring during and after procedures should be provided.

Inferior vena cava (IVC) filters are posited to effect flow dynamics, causing turbulence, vascular remodeling and eventual thrombosis; however, minimal data exists evaluating hemodynamic effects of IVC filters in vivo. The purpose of this study was to determine differences in hemodynamic flow parameters acquired with two-dimension (2D)-perfusion angiography before and after IVC filter placement or retrieval. 2D-perfusion images were reconstructed retrospectively from digital subtraction angiography from a cohort of 37 patients (13F/24M) before and after filter placement (nâ =â 18) or retrieval (nâ =â 23). Average dwell time was 239.5â ±â 132.1 days. Changes in the density per pixel per second within a region of interest (ROI) were used to calculate contrast arrival time (AT), time-to-peak (TTP), wash-in-rate (WIR), and mean transit time (MTT). Measurements were obtained superior to, inferior to, and within the filter. Differences in hemodynamic parameters before and after intervention were compared, as well as correlation between parameters versus filter dwell time. A P value with Bonferroni correction ofâ <.004 was considered statistically significant. After placement, there was no difference in any 2D-perfusion variable. After retrieval, ROIs within and inferior to the filter showed a significantly shorter TTP (1.7 vs 1.4 s, Pâ =â .004; 1.5 vs 1.3 s, Pâ =â .001, respectively) and MTT (1.7 vs 1.4 s, Pâ =â .003; 1.5 vs 1.2 s, Pâ =â .002, respectively). Difference in variables showed no significant correlation when compared to dwell time. 2D-perfusion angiography is feasible to evaluate hemodynamic effects of IVC filters in vivo. TTP and MTT within and below the filter after retrieval were significantly changed, without apparent correlation to dwell time, suggesting a functional hemodynamic delay secondary to filter presence.

Background: Early studies during the COVID-19 pandemic identify the dissonance between feeling anxious about contracting the illness and the innate desire to serve the sick, as a main stressor for students. Purpose: The purpose of this study is to better understand psychological stress and self-reported wellness of Physician Assistant (PA), Physical Therapy (PT), dental, and medical students during the early portions of the COVID-19 pandemic. Methods: We utilized the 10-item Perceived Stress Scale (PSS) together with additional questions to assess self-perceived stress, anxiety, and wellness of healthcare students. Discussion: There were no significant differences in PSS between professions. As PSS increased (indicating more stress), the odds of answering "worse" versus "same" or "better" to descriptions of anxiety level increased (OR: 2.318). Conclusion: Student survey respondents experienced similar levels of perceived stress throughout the COVID-19 pandemic. Institutions should consider students' perceived levels of stress and the many aspects of student wellness that may have been affected by the COVID-19 pandemic.
RESUMEN
During the COVID-19 pandemic, academic health centers suspended clinical clerkships for students. A need emerged for innovative virtual curricula to continue fostering professional competencies. In March 2020, a multidisciplinary team from the University of Nebraska Medical Center had 2 weeks to create a course on the impact of infectious diseases that addressed the COVID-19 pandemic in real time for upper-level medical and physician assistant students. Content addressing social determinants of health, medical ethics, population health, service learning, health security, and emergency preparedness were interwoven throughout the course to emphasize critical roles during a pandemic. In total, 320 students were invited to complete the survey on knowledge gained and attitudes about the course objectives and materials and 139 responded (response rate 43%). Students documented over 8,000 total hours of service learning; many created nonprofit organizations, aligned their initiatives with health systems efforts, and partnered with community-based organizations. Thematic analysis of qualitative evaluations revealed that learners found the greatest value in the emphasis on social determinants of health, bioethics, and service learning. The use of predeveloped, asynchronous e-modules were widely noted as the least effective aspect of the course. The COVID-19 pandemic introduced substantial challenges in medical education but also provided trainees with an unprecedented opportunity to learn from real-world emergency preparedness and public health responses. The University of Nebraska Medical Center plans to create a health security elective that includes traditional competencies for emergency preparedness and interrogates the social and structural vulnerabilities that drive disproportionately worse outcomes among marginalized communities. With further evaluation, many components of the curriculum could be broadly scaled to meet the increasing need for more public health and health security medical education.

OBJECTIVE: The use of nicardipine in congenital cardiac surgery has been guarded given the calcium sensitivity of immature myocardium and paucity of clinical data. Reports of nicardipine use have excluded neonates with single ventricles. The goal of this study was to compare the use of nicardipine and sodium nitroprusside for postoperative blood pressure control in young patients recovering from cardiac surgery. METHODS: All neonates (<30 days) and young infants (31-180 days) who received either sodium nitroprusside or nicardipine as first-line therapy for blood pressure control were retrospectively reviewed. Some patients had multiple index operations and each index operation was counted separately regarding treatment with sodium nitroprusside or nicardipine. RESULTS: A total of 59 patients underwent 70 procedures (24 as neonates and 46 as infants). Nicardipine was administered as initial therapy following 33 procedures (n = 28 patients), and sodium nitroprusside was administered as initial therapy following 37 index procedures (n = 31 patients). The duration of treatment was longer (P = .025) when sodium nitroprusside was the initial treatment. Five (15%) patients that received nicardipine required a second blood pressure management agent, and seven (19%) patients that received sodium nitroprusside required a second agent (P = .66). No adverse events related to titratable antihypertensive therapy were recorded in any treatment group. The use of nicardipine resulted in significant medication cost reduction. Based on average wholesale price, patient costs for sodium nitroprusside use were $182,952 ($5,544/pt), while costs for nicardipine were only $24,960 ($780/pt). CONCLUSIONS: Nicardipine can be safely used as a first-line antihypertensive in infants. The use of nicardipine as initial antihypertensive therapy rather than sodium nitroprusside can lead to a significant reduction in medication costs without jeopardizing clinical outcomes.

PURPOSE: Prior studies suggest a role for promoting recognition of generational differences as a part of workplace ethics. To our knowledge, there is no published comprehensive analysis demonstrating how commonly or by what methods intergenerational dynamics are taught as structured coursework in medical school curricula. To address this gap, we carried out a survey of curriculum leaders of US medical schools to assess the current practices and attitudes toward content related to generational differences in medical school coursework. METHODS: A survey consisting of 23 closed- and open-ended questions that aimed to assess the presence, characteristics, and attitudes of participants towards intergenerational dynamics in medical school coursework was disseminated via email. Curriculum deans at 154 allopathic medical schools were invited to complete the survey and sent one reminder email. Quantitative responses were descriptively analyzed, and qualitative responses were thematically analyzed. RESULTS: The response rate was 38.3%, with the majority (58%) of responding institutions stating that their curriculum did not include coursework on intergenerational dynamics. When taught, the most frequent method of instruction was small-group activities. Most stated that the educational content for intergenerational dynamics has been part of their curriculum for fewer than five years. In total, 34% of respondents agreed that some form of education about intergenerational dynamics should be required during medical education as they felt that content could improve cultural competence. Those that were less supportive of inclusion of intergenerational material stated concerns about stereotyping and the value of generational descriptions. CONCLUSION: Our findings show a heterogeneity of responses on the perceptions and practice of curriculum leaders regarding inclusion of content related to intergenerational differences in medical school education. In summary, we present the first work assessing current practices and attitudes toward content related to the inclusion of material on intergenerational dynamics in undergraduate medical education in US allopathic medical schools.
RESUMEN
Purpose: We evaluated our experience of a multidisciplinary approach to renal mass biopsy (RMB) for small renal masses (SRMs) employing in-office ultrasound (US)-guided biopsy by urology (24%), CT, or US biopsy by interventional radiology (IR) (79%), and endoscopic ultrasound (EUS)-guided biopsy by gastroenterology (GI) (4%). Materials and Methods: A single-institution retrospective review of patients who underwent RMB for SRM from May 2013 to August 2019 was conducted. Data regarding patient demographics, tumor characteristics, biopsy technique, histopathology, and management were collected. Diagnostic rates, concordance with final pathology, complications, and outcomes were analyzed. Results: Of the 192 biopsies reviewed, 63% biopsies were malignant, 20% were benign, and 17% were nondiagnostic. Based on biopsy results, 71 patients (37%) elected active surveillance. Thirty-eight (20%) patients underwent cryoablation, 56 (29%) underwent partial nephrectomy, 14 (7%) underwent radical nephrectomy, and the remaining patients were treated elsewhere. The rate of surgery for benign pathology after pretreatment RMB was 3%. The concordance rate between biopsy and final pathology was 99% for malignancy, 96% for specific pathology subtype, and 85% for renal cell carcinoma grade. Median time from diagnosis to definitive treatment was 97 days (urology: 76, IR: 110 and GI: 54, p = 0.002). Three (1.6%) Clavien I complications were reported. Conclusion: Our multidisciplinary approach to RMB for clinical stage T1a demonstrated favorable safety and diagnostic rates, which effectively directed management strategies and minimized surgery for benign disease. Urologist-performed office biopsies significantly shortened the time from diagnosis to definitive treatment. Our experience with GI EUS biopsy has demonstrated feasibility and safety for tumors that were otherwise not accessible percutaneously.

Competent physicians must be able to self-assess skill level; however, previous studies suggest that medical trainees may not accurately self-assess. We utilized Pathology Milestones (PM) data to determine whether there were discrepancies in self- versus Clinical Competency Committee (CCC) ratings by sex, program year (PGY), time of evaluation, and question category (Patient Care, Medical Knowledge, Systems-Based Practice [SBP], Practice-Based Learning and Improvement [PBL], Professionalism [PRO], and Interpersonal and Communication Skills) and Residency In-Service Examination (RISE) score. We completed retrospective analyses of PM evaluation scores from 2016 to 2019 (n = 23 residents) 2 times per year. Discrepancies in evaluation scores were calculated by subtracting CCC scores from resident self-evaluation scores. There was no significant difference in discrepancy scores between male versus female residents (P = .94). Discrepancy scores among all PGYs were significantly different (P < .0001), with PGY1 tending to overrate the most, followed by PGY2. PGY3 and PGY4 underrated themselves on average compared to CCC ratings, with PGY4 having significantly lower self-ratings than CCC compared to any other PGY. In January, residents underscored themselves and in July residents overscored themselves compared to CCC (P < .0001 for both). Question types resulted in variable discrepancy scores, with SBP significantly lower than and PRO significantly higher than all other categories (P < .05 for both). Increases in RISE score correlated to increases in self- and CCC-scoring. These discrepancies can help trainees improve self-assessment. Discrepancies indicate potential areas for amelioration, such as curriculum adjustments or Milestone's verbiage.
RESUMEN
OBJECTIVE: We retrospectively studied the clinical presentations and outcomes of endovascular management in a mixed pediatric and adult Klippel-Trenaunay syndrome (KTS) population at a single academic medical center. METHODS: We performed a retrospective study of patients with KTS who had been referred for endovascular intervention after evaluation and diagnosis by a multidisciplinary team at a single academic medical center during a 10-year period. The patient demographics, areas affected, presenting symptoms, previous treatments, imaging modalities, endovascular treatment types, number of treatments, and complications were assessed. The technical and clinical success rates were calculated. RESULTS: Twenty-six patients with suspected KTS were evaluated. Of these 26 patients, 20, aged 2 to 75 years, had been diagnosed with KTS using the International Society for the Study of Vascular Anomalies criteria and referred for endovascular management. The left lower extremity was affected most often. The presenting symptoms were pain (80%), edema (70%), bleeding (10%), numbness (25%), and claudication (25%). Of the 20 patients, 16 (80%) had undergone treatment of KTS before presenting to our institution. Magnetic resonance imaging and ultrasound (US) were the most common imaging modalities. Fifteen patients underwent 46 endovascular treatments during the study period. The treatments included 5 endovenous ablations only, 4 US-guided sclerotherapies with endovenous ablation, 5 US-guided sclerotherapies only, and 32 catheter-directed venograms with additional interventions. Localized intravascular coagulopathy was the only procedure-related complication and occurred in one patient after three treatments. The technical success rate was 97.8%, and the clinical success rate was 100%. CONCLUSIONS: Endovascular intervention is safe and effective for KTS patients for whom conservative management has failed. Pain and edema were the most common presenting symptoms. Presenting symptoms may be related to pathology of anomalous veins, orthotopic superficial veins or deep veins. Venous claudication can be present in those with KTS despite patency of the deep venous system. Magnetic resonance imaging and duplex US are frequently used modalities for venous assessment. The complications of endovascular treatment are rare but include localized intravascular coagulopathy.

Lymphatic malformations (LMs) are rare congenital anomalies. LMs are often refractory to standard treatments, including surgical resection, debulking, and sclerotherapy. Use of sildenafil, a phosphodiesterase-5 inhibitor, for treatment of pediatric LMs has been reported with demonstrated benefit to some patients. This case series reports treatment of three patients (aged 14-37 years) suffering from complicated or refractory LMs with a low-dose oral phosphodiesterase-5 inhibitor, resulting in significant clinical improvement.

Phenomenon: Because of its importance in residency selection, the United States Medical Licensing Examination Step 1 occupies a critical position in medical education, stimulating national debate about appropriate score use, equitable selection criteria, and the goals of undergraduate medical education. Yet, student perspectives on these issues and their implications for engagement with health systems science-related curricular content are relatively underexplored. Approach: We conducted an online survey of medical students at 19 American allopathic medical schools from March-July, 2019. Survey items were designed to elicit student opinions on the Step 1 examination and the impact of the examination on their engagement with new, non-test curricular content related to health systems science. Findings: A total of 2856 students participated in the survey, representing 23.5% of those invited. While 87% of students agreed that doing well on the Step 1 exam was their top priority, 56% disagreed that studying for Step 1 had a positive impact on engagement in the medical school curriculum. Eighty-two percent of students disagreed that Step 1 scores should be the top item residency programs use to offer interviews. When asked whether Step 1 results should be reported pass/fail with no numeric score, 55% of students agreed, while 33% disagreed. The majority of medical students agreed that health systems science topics were important but disagreed that studying for Step 1 helped learn this content. Students reported being more motivated to study a topic if it was on the exam, part of a course grade, prioritized by residency program directors, or if it would make them a better physician in the future. Insights: These results confirm the primacy of the United States Medical Licensing Examination Step 1 exam in preclinical medical education and demonstrate the need to balance the objectives of medical licensure and residency selection with the goals of the broader medical profession. The survey responses suggest several potential solutions to increase student engagement in health systems science curricula which may be especially important after Step 1 examination results are reported as pass/fail.

BACKGROUND: Morbidly adherent placenta, also known as placenta accreta spectrum, is associated with severe maternal morbidity and mortality. Multiple adjunctive procedures have been proposed to improve outcomes, and at many institutions, interventional radiologists will play a role in assisting obstetricians in these cases. OBJECTIVE: The objective of the study was to evaluate the outcomes of women with morbidly adherent placenta who underwent cesarean hysterectomy with aortic balloon occlusion or internal iliac artery balloon occlusion catheters, compared with cesarean hysterectomy with surgical ligation of the iliac arteries, or cesarean hysterectomy without adjunctive procedures. STUDY DESIGN: A retrospective review of women with morbidly adherent placenta treated with cesarean hysterectomy was performed at 5 institutions from May 2014 to April 2018. The balloon occlusion group had either prophylactic aortic or iliac balloons placed prior to cesarean hysterectomy. Comparison groups included those who underwent internal iliac artery ligation prior to hysterectomy or a control group if they underwent cesarean hysterectomy without adjuvant procedures. Evaluated outcomes include estimated blood loss, transfusion requirements, intensive care unit admission, and adverse event rates. RESULTS: There were 171 women with morbidly adherent placenta included in the study. Twenty-eight had balloon placement prior to cesarean hysterectomy, 18 had intraoperative internal iliac artery ligation, and there were 125 control women who underwent cesarean hysterectomy without any adjunctive procedures. Compared with the women who underwent cesarean hysterectomy without adjunctive procedures, women who underwent aortic or iliac artery balloon occlusion prior to hysterectomy had significantly lower estimated blood loss (30.9% decrease, P < .001), transfusion requirements (76.8% decrease, P < .001), intensive care unit admission rates (0% vs 15.2%, P < .001), and intensive care unit stay lengths (0.0 vs 3.1 days, P < .001). Compared with women who underwent surgical ligation of the internal iliac arteries prior to hysterectomy, women who underwent aortic or iliac artery balloon occlusion prior to cesarean hysterectomy had lower estimated blood loss (54.2% decrease, P < .01), transfusion requirements (90.5% decrease, P < .001), operating room times (40.0% decrease, P < .01), intensive care unit admissions rates (0% vs 77.8%, P < .001), intensive care unit stay lengths (0.0 vs 1.4 days, P < .001), and adverse events (3.6% vs 44.4%, P < .01). CONCLUSION: Aortic and iliac artery balloon occlusion are associated with lower estimated blood loss, transfusion requirements, intensive care unit admission rates, and adverse event rates compared with women who underwent internal iliac artery ligation prior to cesarean hysterectomy or women who had no adjunctive interventions prior to cesarean hysterectomy for morbidly adherent placenta.

BACKGROUND: Pseudoaneurysms (PAs) caused by traumatic injury to the arterial vasculature have a high risk of rupture, leading to life-threatening hemorrhage and mortality, requiring urgent treatment. The purpose of this study was to determine the technical and clinical outcomes of endovascular treatment of visceral and extremity traumatic pseudoaneurysms. METHODS: Clinical data were retrospectively collected from all patients presenting for endovascular treatment of PAs between September 2012 and September 2018 at a single academic level one trauma center. Technical success was defined as successful treatment of the PA with no residual filling on post-embolization angiogram. Clinical success was defined as technical successful treatment with no rebleeding throughout the follow-up period and no reintervention for the PA. RESULTS: Thirty-five patients (10F/25M), average age (± stdev) 41.7 ± 20.1 years, presented with PAs secondary to blunt (n = 31) or penetrating (n = 4) trauma. Time from trauma to intervention ranged from 2 h - 75 days (median: 4.4 h, IQR: 3.5-17.1 h) with 27 (77%) of PAs identified and treated within 24 h of trauma. Average hospitalization was 13.78 ± 13.4 days. Ten patients underwent surgery prior to intervention. PA number per patient ranged from 1 to 5 (multiple diffuse). PAs were located on the splenic (n = 12, 34.3%), pelvic (n = 11, 31.4%), hepatic (n = 9, 25.7%), upper extremity/axilla (n = 2, 5.7%), and renal arteries (n = 1, 2.9%). Technical success was 85.7%. Clinical success was 71.4%, for technical failure (n = 5), repeat embolization (n = 1) or post-IR surgical intervention (n = 4). There was no PA rebleeding or reintervention for any patient after discharge over the reported follow-up periods. Three patients died during the trauma hospitalization for reasons unrelated to the PAs. CONCLUSIONS: Endovascular treatment of traumatic visceral and extremity PAs is efficacious with minimal complication rates and low reintervention requirements.
RESUMEN
OBJECTIVES: To compare perioperative outcomes related to atherectomy with percutaneous transluminal angioplasty versus percutaneous transluminal angioplasty alone for the treatment of lower extremity chronic limb threatening ischemia using a national patient database. METHODS: Patients with chronic limb threatening ischemia treated with atherectomy and percutaneous transluminal angioplasty or percutaneous transluminal angioplasty alone from 2011 to 2016 in the National Surgical Quality Improvement Program database were identified. Primary outcomes were major adverse limb events (30-day untreated loss of patency, major reintervention, major amputation) and major adverse cardiac events (cardiac arrest, composite outcome of myocardial infarction or stroke). Secondary outcomes included 30-day mortality, length of stay, and any unplanned readmission within 30 days. Multivariate regression analyses were performed to determine independent predictors of outcome. Propensity score matched cohort analysis was performed. A p-value <0.05 was considered statistically significant. Subgroup analyses of femoropopliteal and infrapopliteal interventions were performed. RESULTS: In total, 2636 (77.2%) patients were treated with percutaneous transluminal angioplasty and 778 (22.8%) were treated with atherectomy and percutaneous transluminal angioplasty. Multivariate analyses of the unadjusted cohort revealed no significant differences in major adverse cardiac events or major adverse limb events between the two groups (p-value >0.05). Subgroup analysis of femoropopliteal interventions demonstrated a significantly decreased likelihood of untreated loss of patency in 30 days in the atherectomy group compared to the percutaneous transluminal angioplasty group (1.1% vs. 2.7%, respectively; p-value = 0.034), which persisted on propensity score matched analysis (1.1% vs. 3.1%, respectively; p-value = 0.026). CONCLUSION: Atherectomy with balloon angioplasty of femoropopliteal disease provides a significant decrease in untreated loss of patency compared to balloon angioplasty alone.

Infants undergoing congenital heart surgery (CHS) with cardiopulmonary bypass (CPB) are at risk of acute kidney injury (AKI) and fluid overload. We hypothesized that placement of a passive peritoneal drain (PPD) can improve postoperative fluid output in such infants. We analyzed 115 consecutive patients, age birth to 60 days, admitted to the PICU after CHS with CPB between 2012 and 2018. Patients who needed postoperative ECMO were excluded. Linear and logistic regression models compared postoperative fluid balances, diuretics administration, AKI, vasoactive-inotropic scores (VIS), time intubated, and length of stay after adjusting for pre/operative predictors including STAT category, bypass time, age, weight, and open chest status. PPD patients had higher STAT category (p = 0.001), longer CPB times (p = 0.001), and higher VIS on POD 1-3 (p ≤ 0.005 daily). PPD patients also had higher AKI rates (p = 0.01) that did not reach significance in multivariable modeling. There were no postoperative deaths. Postoperative hours of intubation, hospital length of stay, and POD 1-5 fluid intake did not differ between groups. Over POD 1-5, PPD use accounted for 48.8 mL/kg increased fluid output (95% CI [2.2, 95.4], p = 0.043) and 3.41 mg/kg less furosemide administered (95% CI [1.69, 5.14], p < 0.001). No PPD complications were observed. Although PPD placement did not affect end-outcomes, it was used in higher acuity patients. PPD placement is associated with improved fluid output despite lower diuretic administration and may be a useful postoperative fluid management adjunct in some complex CHS patients.

Brown-Sequard Syndrome is a neurologic disorder caused by partial spinal cord injury and disruption of the corticospinal tract, dorsal columns, and spinothalamic tract. We present a 32-year-old male with partial T11-12 cord transection due to a penetrating knife injury. In addition to the classical neurological symptoms of Brown-Sequard Syndrome, he also exhibited ipsilateral peripheral vasodilatation below the level of injury. This finding is attributed to the disruption of the intermediolateral columns of the spinal cord and impaired sympathetic tone on the peripheral vasculature. Awareness of this finding can raise the radiologist's suspicion for spinal cord injury in the setting of trauma and peripheral vasodilation.
