RESUMO
BACKGROUND: The significance of lymphovascular invasion (LVI) in esophageal adenocarcinoma (EAC) has not yet been described. Potential utility as an adjunct to current staging guidelines remains unknown. METHODS: The National Cancer Database was queried from 2006 to 2020. Univariate and multivariable models, Kaplan Meier method, and log-rank test were used. Subgroup analyses by pN stage were conducted. RESULTS: Of 9,689 patients, 23.2% had LVI. LVI was an independent prognostic factor (hazard ratio [HR] 1.401, 95% confidence interval [CI] 1.307-1.502, p < 0.0001) with reduction in median survival to 20.0 months (95% CI 18.9-21.4) from 39.7 months (95% CI 37.8-42.3, p < 0.0001). Multivariable survival analysis adjusted on pN and pT stage found that patients with LVI had decreased survival in a given pN stage (p < 0.001). pN0/LVI+ patients had a similar prognosis to the higher staged pN1/LVI- (28.6 months), although pN1/LVI- patients did slightly worse (p = 0.0135). Additionally, patients with pN1/LVI+ had equivalent survival compared with pN2/LVI- (p = 0.178) as did pN2/LVI+ patients compared with pN3/LVI- (p = 0.995). CONCLUSIONS: In these data, LVI is an independent negative prognostic factor in EAC. LVI was associated with a survival reduction similar to an upstaged nodal status irrespective of T stage. Patients with LVI may be better classified at a higher pN stage.
RESUMO
INTRODUCTION: Obese patients often have higher complication rates after elective general surgeries; however, few studies have examined the outcomes after thyroidectomy. This study examines whether increased body mass index (BMI) is associated with poor postoperative outcomes after thyroid surgery. METHODS: A retrospective review of patients who underwent thyroidectomy from 2015 to 2018 was performed. Demographics, comorbidities, pathology, and extent of resection (total versus hemithyroidectomy) were examined. Patients were classified into BMI groups according to the WHO definitions, and the incidence of surgical outcomes was determined in each group. Surgical outcomes of interest included readmission rates (RRs), length of stay, average operating room time, return to the operating room, hypocalcemia, postop infections, hematomas, and recurrent laryngeal nerve injury. Between-subjects statistics including independent samples t-test, ANOVA, and chi-square analyses were performed. RESULTS: There were n = 465 patients included with a mean BMI 32.35 (standard deviation = 8.55) and median BMI 30.78 (Q1 = 26.26, Q3 = 36.73). There were no differences between BMI groups in age, gender, smoking, heart disease. There was a positive association between increased BMI and postoperative infection (P < 0.001), pneumonia (P = 0.018), and surgical site infection (P = 0.04), which were highest for BMI > 40. Increased BMI was associated with a higher 30-d RR (P = 0.008), particularly for BMI >40 versus BMI <40 (6.2% versus 1.05%; P = 0.003). There were no significant differences between surgical outcomes for patients with increased BMI who underwent total thyroidectomy or hemithyroidectomy. CONCLUSIONS: Excellent postoperative outcomes were observed in all BMI categories. Higher postoperative infection and 30-d RRs were observed in the morbidly obese. Contrary to previous studies, operating room times were similar regardless of BMI.

INTRODUCTION: The mainstay of successful treatment for parathyroid carcinoma remains complete surgical excision. Although intraoperative parathyroid hormone (ioPTH) monitoring is a useful adjunct during parathyroidectomy for benign primary hyperparathyroidism, its utility for parathyroid carcinoma remains unclear. METHODS: A retrospective review of 796 patients who underwent parathyroidectomy with ioPTH monitoring for primary hyperparathyroidism revealed 13 patients with parathyroid carcinoma on final pathology from two academic institutions. A systematic review yielded 5 additional parathyroid carcinoma patients. Complete excision of malignancy, or operative success (eucalcemia ≥6 mo. after parathyroidectomy); operative failure (persistent hypercalcemia <6 mo. after parathyroidectomy); and perioperative complications were evaluated. Comparison of the >50% ioPTH decrease alone to >50% ioPTH decrease into normal reference range was analyzed using Chi-squared, Kolmogorov-Smirnov, Kruskal-Wallis tests. RESULTS: All 18 parathyroid carcinoma patients achieved a >50% ioPTH decrease, and 14 patients also had a final ioPTH level decrease into normal reference range. 93% of patients who met normal parathyroid hormone reference range had operative success, whereas only two of the four (50%) patients with parathyroid carcinoma with a >50% ioPTH decrease alone demonstrated operative success. CONCLUSIONS: Parathyroidectomy guided by a >50% ioPTH decrease into normal reference range may better predict complete excision of malignant tissue in patients with parathyroid carcinoma compared to >50% ioPTH decrease alone. IoPTH monitoring should be used in conjunction with clinical judgment and complete en bloc resection for optimal treatment and success.

BACKGROUND: This study aimed to evaluate how enhanced recovery (ER) protocols and same-day discharge (SDD) influences patients' postoperative quality of life (QOL). METHODS: Patients who underwent mastectomy with implant-based breast reconstruction from 2008 to 2020 were identified in a prospective database. The study assessed QOL with BREAST-Q and Was It Worth It? (WIWI) questionnaires. Responses were compared between the ER and pre-ER groups and between the SDD and hospital stay (HS) groups using one-way analysis of variance (ANOVA) and chi-square tests. RESULTS: The inclusion criteria were met by 568 patients, with a 43% response rate, and 217 patients were included for analysis. Chest physical well-being was lower for the ER cohort, but postoperative breast satisfaction was higher. Psychosocial status, sexual well-being, and satisfaction with information given did not differ significantly between the ER group and the pre-ER or SDD group. In the compared groups, QOL did not differ significantly. CONCLUSIONS: Enhanced recovery with SDD after mastectomy using implant-based reconstruction did not have an adverse impact on patient postoperative QOL.

BACKGROUND: Recent data show that aesthetic surgery research is lagging compared with reconstructive surgery: research funding and institutional disparities within aesthetic surgery are potential factors in this trend. OBJECTIVES: The authors sought to determine if disparities exist in aesthetic surgery research based on funding sources or practice settings. METHODS: The authors reviewed Aesthetic Surgery Journal articles from 2009 to 2019. Chi-square, t test, bivariate, and multivariate regression analyses were employed to evaluate research trends. RESULTS: A total of 2262 publications were identified, with 318 funded articles meeting inclusion criteria. The majority of studies (294, 92%) received external funding, with 281 (88%) being supported solely by external funds. Externally funded studies were financed by private industry (194, 66%), foundations/societies (53, 18%), government grants (23, 8%), or a combination of agencies (24, 8%). The majority of funded studies were at academic institutions (266, 84%), followed by private practice (46, 14%) and private industry (6, 2%). Analysis of annual publications revealed a rising percentage of academic-based research, which correlated with decreasing research from private practice (râ =â -0.95, r2â =â 0.89, Pâ <â 0.001). Compared with academic institutions, private practice relied more heavily on industry funding (55% vs 87%, respectively, Pâ =â 0.001), exhibiting lower rates of foundational/societal (20% vs 2%), governmental (9% vs 0%), combined (8% vs 7%), and internal department funding (8% vs 4%). Article citations and level of evidence were unaffected by funding source, agency, or practice setting. CONCLUSIONS: Lack of diversity in research funding among private practice surgeons may explain the reported discrepancies that currently exist between aesthetic and reconstructive surgery research.

The incidence of pancreatic neuroendocrine tumors (PNETs) is on the rise primarily due to the increasing use of cross-sectional imaging. Most of these incidentally detected lesions are non-functional PNETs with a small proportion of lesions being hormone-secreting, functional neoplasms. With recent advances in surgical approaches and systemic therapies, the management of PNETs have undergone a paradigm shift towards a more individualized approach. In this manuscript, we review the histologic classification and diagnostic approaches to both functional and non-functional PNETs. Additionally, we detail multidisciplinary approaches and surgical considerations tailored to the tumor's biology, location, and functionality based on recent evidence. We also discuss the complexities of metastatic disease, exploring liver-directed therapies and the evolving landscape of minimally invasive surgical techniques.
RESUMO
BACKGROUND: Focused parathyroidectomy (F-PTX) guided by intraoperative parathormone (ioPTH) monitoring may result in higher operative failure rates from missed multiglandular disease (MGD) in patients with sporadic primary hyperparathyroidism (spHPT) when ioPTH levels do not reach normal range. METHODS: A retrospective review included 690 patients with spHPT who underwent F-PTX and ioPTH monitoring were divided into 2 groups: >50% ioPTH decrease to normal range, and >50% ioPTH decrease to above normal range. Operative success, recurrence, bilateral/unilateral neck exploration (BNE/UNE), MGD were evaluated. RESULTS: 533 patients demonstrated >50% ioPTH decrease to normal range, and 157 patients >50% ioPTH decrease to above normal range. There were no differences in operative success 99% vs. 97%, recurrence 2.5% vs. 5%, BNE 12% vs. 11%, UNE 4% vs. 5%, or MGD 4% vs. 4%, (p > 0.05) with 46 months mean follow-up. CONCLUSIONS: There were no differences in operative success, failure, BNE, UNE or MGD regardless of ioPTH criterion used for F-PTX.

BACKGROUND: Primary hyperparathyroidism consists of 3 biochemical phenotypes: classic, normocalcemic, and normohormonal primary hyperparathyroidism. The clinical outcomes of patients with normocalcemic primary hyperparathyroidism and normohormonal primary hyperparathyroidism are not well described. METHOD: A retrospective review of patients who underwent parathyroidectomy at a single institution was performed. A logistical regression analysis of postoperative nephrolithiasis and highest percentage change in dual-energy x-ray absorptiometry scan comparison using Kruskal-Wallis test and Cox proportional hazard analysis of recurrence-free survival were performed. RESULTS: A total of 421 patients were included (340 classic, 39 normocalcemic primary hyperparathyroidism, 42 normohormonal primary hyperparathyroidism). Median follow-up was 8.8 months (range 0-126). Higher rates of multigland disease were seen in normocalcemic primary hyperparathyroidism (64.1%) and normohormonal primary hyperparathyroidism (56.1%) compared to the classic (25.8%), P < .001. There were no differences in postoperative complications. The largest percentage increases in bone mineral density at the first postoperative dual-energy x-ray absorptiometry scan were higher for classic (mean ± SD, 6.4 ± 9.1) and normocalcemic primary hyperparathyroidism (4.8 ± 11.9) compared to normohormonal primary hyperparathyroidism, which remained stable (0.2 ± 14.2). Normocalcemic primary hyperparathyroidism were more likely to experience nephrolithiasis postoperatively, 6/13 (46.2%) compared to 11/68 (16.2%) classic, and 2/13 (15.4%) normohormonal primary hyperparathyroidism, P = .0429. Normocalcemic primary hyperparathyroidism was the only univariate predictor of postoperative nephrolithiasis recurrence (odds ratio [95% confidence interval] 4.44 [1.25-15.77], P = .029). Normocalcemic primary hyperparathyroidism was significantly associated with persistent disease with 6/32 (18.8%) compared to 1/36 (2.8%) and 3/252 (1.2%) in normohormonal primary hyperparathyroidism and classic (P < .001). CONCLUSION: Three phenotypes of primary hyperparathyroidism are distinct clinical entities. Normocalcemic primary hyperparathyroidism had higher incidence of persistent disease and postoperative nephrolithiasis but demonstrated improvements in postoperative bone density. These data should inform preoperative discussions with patients with normocalcemic primary hyperparathyroidism and normohormonal primary hyperparathyroidism regarding postoperative expectations.

BACKGROUND: Despite the significant clinical consequences and socioeconomic costs of gunshot wounds to the head (GSWH), studies examining prehospital risk factors, geospatial patterns, and economic cost are lacking. METHODS: A retrospective analysis was performed for patients with GSWH (single or multiple injuries) presenting to the level one Ryder Trauma Center (hospital patients) as well as the Miami-Dade County Medical Examiner (ME) Department, from October 2013 to October 2015. In addition, ME data were queried from the previous decade (2008-2017) to analyze longitudinal trends. RESULTS: A total of 402 consecutive patients met the inclusion criteria: 297 (74%) presented to the ME and 105 (26%) presented to the hospital. GSWH in our cohort had a case fatality rate of 89%, predominantly affecting males, whites, and individuals who committed suicide, with a mean age of 41.9 ± 20.6 years. Hospital patients were more likely to be black males from low socioeconomic status (SES) regions involved in assault. Older white males were overrepresented in patients attempting and completing suicide and thus comprised a higher percentage of ME cases. Geospatial analysis of hospital patient injury zip codes shows that GSWH are significantly clustered in low-income urban centers with greater poverty rates. In Miami-Dade County, the economic burden of GSWH, as measured by total health care costs and lifetime productivity losses, was estimated to be $11,867,415 and $246,179,498, respectively. CONCLUSIONS: In the first analysis of GSWH with the inclusion of both hospital and ME data in a representative urban setting, our findings show prehospital risk factors and the unequal distribution of the significant economic costs of GSWH.

BACKGROUND: The effect of postoperative sensation on quality-of-life (QoL) following nipple-sparing mastectomy (NSM) with implant-based reconstruction is not well described. We evaluated the impact of breast and nipple sensation on patient QoL by using BREAST-Q. METHODS: Patients undergoing NSM with implant reconstruction from 2008 to 2020 were mailed a survey to characterize their postoperative breast and nipple sensation. BREAST-Q metrics were compared between totally numb patients and those with sensation. RESULTS: A total of 349 patients were included. Overall, 131 (38%) responded; response rates regarding breast and nipple sensation were 36% (N = 124/349) and 34% (N = 117/349). Median time from surgery to survey completion was 6 years. The majority had bilateral procedures (101, 77%), including direct-to-implant (99, 76%) and tissue expander (32, 24%) reconstruction. Regarding breast sensation, the majority of patients reported their reconstructed breasts as totally numb (47, 38%) or much less sensation than before surgery (59, 48%). Regarding nipple sensation, the majority of patients reported their nipples were totally numb (67, 57%) or had much less sensation than before surgery (37, 32%). Total numbness of reconstructed breasts resulted in a significantly lower chest physical well-being (mean score: 73.5 vs. 81.2, respectively, P = 0.048). Total numbness of postoperative nipple(s) resulted in significantly lower chest physical (mean score: 74.8 vs. 85.2, respectively, P = 0.007), psychosocial (mean score 77.4 vs. 84.4, respectively, P = 0.041), and sexual well-being (mean score: 55.7 vs. 68.3, respectively, P = 0.002). CONCLUSIONS: Long-term breast and nipple sensation are significantly diminished after NSM with implant reconstruction. Patients with preserved sensation experience better physical, psychosocial, and sexual well-being.

INTRODUCTION: Coat's plus syndrome is an extremely rare genetic syndrome that leads to a variety of symptoms. We are reporting a case of Coat's plus syndrome that had persistent GI bleeding and review of current literature. PRESENTATION OF CASE: The patient is a female in her 40â¯s with a history of coat's disease and end stage renal failure on dialysis. The etiology of renal failure was not discovered, and the patient was being worked up for a kidney transplant. The patient required admission after deterioration of nutritional status with a BMI of 14.3. During admission the patient initially had intermittent GI bleeding requiring weekly blood transfusions. On work up of the GI bleed, no etiology was identified either. As a result persistent negative GI bleed work up, we pursued alternative diagnoses. The history of Coat's disease prompted us to work up the patient for Coat's plus syndrome. A genetic test confirmed the presence of CTC-1 gene mutation, which results in Coat's plus syndrome. With no treatment available as of yet, the patient continued to deteriorate into multi-organ failure. DISCUSSION: We present an example of GI bleeding in Coat's plus syndrome, only identified thru genetic testing, that is very rare and complex in nature. Despite numerous workups, no specific etiology was identified for the GI bleeding. CONCLUSION: Previous reports have not investigated cause of GI bleeding, since it is extremely rare in the literature. Further investigation is warranted to understand cause and effects of GI bleeding in this rare genetic disease.
RESUMO
INTRODUCTION: There is a wide differential diagnosis for intraabdominal tumors. Surgical resection and microscopic analysis of tissue structure can identify tumor origin in most cases. Most rapidly growing invasive tumors are neoplastic. Inflammatory pseudotumors are a subcategory of intraabdominal tumors that are non-neoplastic and can be rapidly growing. Urachal cysts originate from the dome of the bladder; however they are typically not invasive. There is limited literature on the appropriate management of these tumors. PRESENTATION: A 37-year-old female presenting with symptoms of abdominal pain was found to have a large intraabdominal mass invading multiple organs. Core biopsies demonstrated inflammation. The mass grew significantly over the course of a year and patient's abdominal pain worsened. The patient was taken to the operating room for resection. Final pathology revealed reactive fibrous tissue with acute and chronic inflammation invading bladder, urethra, abdominal wall, appendix, and ovary. Intraoperative frozen section demonstrated low grade spindle cells with concern for inflammatory pseudotumor but final pathology demonstrated inflammation. DISCUSSION: Although benign, these tumors cause significant morbidity due to their size and level of organ invasion. Management should involve surgical resection as well as potential post-operative chemotherapy or NSAIDs based off clinical picture. We demonstrate the importance of close follow up for residual disease or recurrence of patients with inflammatory pseudotumors of the abdomen. CONCLUSION: This case highlights difficulties in diagnosis of a tumor that has potential to cause significant morbidity. There is need for further research to discover the best management after surgical resection of these tumors.
RESUMO
RATIONALE AND OBJECTIVES: Peer learning is a case-based group-learning model intended to improve performance. In this descriptive paper, we describe multi-institutional, multi-subspecialty, web-based radiology case conferences and summarize the participants' experiences. MATERIALS AND METHODS: A semi-structured, 27-question survey was administered to radiologists participating in abdominal, cardiothoracic, and musculoskeletal case conferences. Survey questions included demographics, perceived educational value and challenges experienced. Survey question formats were continuous, binary, five-point Likert scale or text-based. The measures of central tendencies, proportions of responses and patterns were tabulated. RESULTS: From 57 responders, 12/57 (21.1%) were abdominal, 16/57 (28.1%) were cardiothoracic, and 29/57 (50.8%) were musculoskeletal conference participants; 50/56 (89.3%) represented academic practice. Median age was 45 years (range 35-74); 43/57 (75.4%) were male. Geographically, 16/52 (30.8%) of participants were from the East Coast, 16/52 (30.8%) Midwest, 18/52 (34.6%) West Coast, and 2/52 (3.8%) International. The median reported educational value was 5/5 (interquartile range 5-5). Benefits of the case conference included education (50/95, 52.6%) and networking (39/95, 41.1%). Participants reported presenting the following cases: "great call" 32/48 (66.7%), learning opportunity 32/48 (66.7%), new knowledge 41/49 (83.7%), "zebras" 46/49 (93.9%), and procedural-based 16/46 (34.8%). All 51/51 (100%) of responders reportedly gained new knowledge, 49/51 (96.1%) became more open to group discussion, 34/51 (66.7%) changed search patterns, and 50/51 (98%) would continue to participate. Reported challenges included time zone differences and support from departments for a protected time to participate. CONCLUSION: Peer learning through multi-institutional case conferences provides educational and networking opportunities. Current challenges and desires include having department-supported protected time and ability to receive continuing medical education credit.

BACKGROUND: In recent years, there have been significant changes in the perception of valvular and vascular allograft transplants. Despite the constant evolution of the field of transplant and the involvement of multiple surgical specialties, there is not an official registry for administrative and clinical control. This study aims to design a registry of vascular and valvular allograft transplantation in Catalonia, Spain (ReVAC). MATERIALS AND METHODS: Three consecutive focal groups were designed. Focal groups established administrative, technical, and clinical requirements of ReVAC. ReVAC included patients with a transplanted cryopreserved vascular segment or cardiac valves that were distributed by Catalan tissue banks to public and private hospitals in Catalonia. Ten hospitals were involved in this study. Data were collected on 380 patients between January 1995 and November 2015. RESULTS: The project resulted in the completion of a growing platform available online. ReVAC was divided into the following 3 levels: patient-related, surgery-related, and transplant-related data. Online access is available through the website of applications of the "Generalitat de Catalunya." CONCLUSION: ReVAC has been useful for administrative and clinical control of transplants in Catalonia. Currently, data related to outcomes of arterial allografts are available, reinforcing the current guideline-supported indications, as well as opening a window for further analysis and guideline creation.

OBJECTIVEDiscitis and osteomyelitis are seen in end-stage renal disease (ESRD) patients due to repeated vascular access for hemodialysis and urinary tract infections leading to recurrent bacteremia. Discitis and osteomyelitis are underdiagnosed due to the nonspecific initial presentation of back pain. In this article, we review the literature for better understanding of the problem and the importance of early diagnosis by primary care physicians and nephrologists. In addition, we discuss the decision-making, follow-up, management, and neurological outcomes.METHODSA detailed PubMed search was performed using the following terms: "end stage renal disease (ESRD)" and "chronic renal failure (CRF)," combined with "spine infections," "spondylodiscitis," "discitis," and "osteomyelitis." Search results were limited to articles written in English, case reports, and case series from 1973 to 2012. Editorials, reviews, and commentaries were excluded. Only studies involving human patients were included. The authors also included 4 patients from their own patient population.RESULTSA total of 30 articles met the inclusion criteria. Including the 4 patients from the authors' patient population, 212 patients with spine infections and maintenance dialysis were identified. The patients' ages ranged from 38 to 78 years. The duration of dialysis ranged from a few days to 16 years. The time from onset of back pain to diagnosis ranged from 3 days to 6 months. The most common causative organism was Staphylococcus aureus, followed by Staphylococcus epidermidis and gram-negative bacteria. Most of the patients were treated with antibiotics alone (76.8%), although surgery was indicated when patients presented with neurological deficits (p < 0.011). Approximately one-quarter of the patients developed neurological deficits, with devastating consequences. Fever and neurological deficits at presentation, culture positive for methicillin-resistant S. aureus, and age > 65 years were highly correlated with mortality in our analysis.CONCLUSIONSSeveral risk factors lead to failure of antibiotics and progression of disease in patients with ESRD. Challenges to diagnosis include vague presenting symptoms, co-existing destructive spondyloarthropathy, poor immune response, chronic elevations of inflammatory markers, and recurrent bacteremia. Infectious processes are more likely to cause permanent neurological deficits than transient deficits. The authors recommend close observation and serial imaging of these patients for early signs of neurological deficits. Any signs of disease progression will require aggressive surgical debridement.
RESUMO
Central neurocytomas are rare tumors, typically found in the third ventricle. We present the unusual case of a fourth ventricular central neurocytoma in a 70-year-old female presenting with imbalance and headaches, with an enhancing fourth ventricular mass on imaging. We examine the details of her clinical presentation, imaging characteristics, histopathologic analysis, and postoperative course. We performed a critical literature review of fourth ventricular central neurocytoma, identifying 6 previously reported cases. In contrast to our patient, the majority of these cases were in young males. The 2 females with fourth ventricular neurocytoma developed it at a much later age (mean 63.5 years) than their male counterparts (mean 22.8 years; P = 0.005). Despite being a rare cause for a fourth ventricular lesion, given the appropriate clinical context and radiographic findings, this should remain part of the differential diagnosis.

OBJECTIVE Carotid body tumors (CBTs), extraadrenal paragangliomas, are extremely rare neoplasms in children that often require multimodal surgical treatment, including preoperative anesthesia workup, embolization, and resection. With only a few cases reported in the pediatric literature, treatment paradigms and surgical morbidity are loosely defined, especially when carotid artery infiltration is noted. Here, the authors report two cases of pediatric CBT and provide the results of a systematic review of the literature. METHODS The study was divided into two sections. First, the authors conducted a retrospective review of our series of pediatric CBT patients and screened for patients with evidence of a CBT over the last 10 years (20072017) at a single tertiary referral pediatric hospital. Second, they conducted a systematic review, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, of all reported cases of pediatric CBTs to determine the characteristics (tumor size, vascularity, symptomatology), treatment paradigms, and complications. RESULTS In the systematic review (n = 21 patients [includes 19 cases found in the literature and 2 from the authors' series]), the mean age at diagnosis was 11.8 years. The most common presenting symptoms were palpable neck mass (62%), cranial nerve palsies (33%), cough or dysphagia (14%), and neck pain (19%). Metastasis occurred only in 5% of patients, and 19% of cases were recurrent lesions. Only 10% of patients presented with elevated catecholamines and associated sympathetic involvement. Preoperative embolization was utilized in 24% of patients (external carotid artery in 4 and external carotid artery and vertebral artery in 1). Cranial nerve palsies (cranial nerve VII [n = 1], IX [n = 1], X [n = 4], XI [n = 1], and XII [n = 3]) were the most common cause of surgical morbidity (33% of cases). The patients in the authors' illustrative cases underwent preoperative embolization and balloon test occlusion followed by resection, and both patients suffered from transient Horner's syndrome after embolization. CONCLUSIONS Surgical management of CBTs requires an extensive preoperative workup, anesthesia, and multimodal surgical management. Due to a potentially high rate of surgical morbidity and vascularity, balloon test occlusion with embolization may be necessary in select patients prior to resection. Careful thorough preoperative counseling is vital to preparing families for the intensive management of these children. ABBREVIATIONS BTO = balloon test occlusion; CBT = carotid body tumor; CN = cranial nerve; ECA = external carotid artery; ICA = internal carotid artery; MIBG = iodine-123-meta-iodobenzylguanidine; PRISMA = Preferred Reporting Items for Systematic Reviews and Meta-Analyses.
