RESUMO
OBJECTIVE(S): Despite advancements in imaging techniques and cytological analysis, plunging ranula remains a challenging surgical, radiologic, and pathologic phenomenon. Of the 18 patients we evaluated at our institution, we highlight three cases that illustrate the high rate of misleading imaging and cytological results when assessing plunging ranula. METHODS: Imaging results, biopsy findings, operative techniques, and pathological reports were reviewed from patients who had either a preoperative or postoperative diagnosis of ranula and underwent surgery by a single head and neck surgeon at a tertiary care center. RESULTS: Of the 18 identified patients, computed tomography was correct on preoperative imaging 73% of the time and magnetic resonance imaging was correct on preoperative imaging 71% of the time. Two patients underwent preoperative ultrasound and their ultrasound reports did not accurately diagnose the presence of a ranula. Two patients underwent preoperative fine needle aspiration biopsy due to inconclusive preoperative imaging, in which results suggested either a ranula or epidermal cyst. Both ultimately did not match the final pathology. Three of eighteen patients (17%) underwent an inappropriate initial surgery due to incorrect imaging diagnoses and/or biopsy findings. CONCLUSION: Despite use of preoperative modalities to distinguish plunging ranula from other cystic floor of mouth lesions, surgeons must be aware that no workup modality is fully precise. The potential for revision surgery must be included in all preoperative discussions for presumed plunging ranula. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:2689-2696, 2024.

OBJECTIVE: The primary objective of this study was to evaluate oncologic outcomes of all published cases of supracricoid partial laryngectomy (SCPL) performed in the United States. The secondary objective was to assess the functional outcomes associated with this procedure. REVIEW METHODS: A systematic review of PubMed, SCOPUS, and Embase for all English-language studies pertaining to SCPL performed in the United States was conducted until August 2021. Primary outcomes included disease-specific survival (DSS), overall survival, and local recurrence rate. Secondary outcomes included larynx preservation rate, gastrostromy tube dependency, days to gastrostomy tube removal, decannulation rate, and days to decannulation. RESULTS: A total of six studies were included in the analysis. A total of 113 patients (58.5%) underwent SCPL surgery as a primary treatment method whereas 80 patients (41.5%) underwent SCPL as salvage surgery. The 5-year DSS rates were 87.8% and 100% for primary and salvage procedures, respectively. Approximately 10.3% of patients undergoing a salvage SCPL procedure experienced a local recurrence whereas only 1.85% of primary SCPL procedures resulted in local recurrence. The rates of decannulation following primary and salvage SCPL were 92.7% and 88.1%, respectively. With regard to swallowing, primary and salvage SCPL procedures demonstrated comparably low postoperative gastrostomy tube dependency rates of 3.66% and 4.76%, respectively. CONCLUSIONS: SCPL performed in the United States is an effective surgical technique that produces excellent outcomes in qualifying patients, thus validating its viability as an organ-preserving surgical alternative.

OBJECTIVE: Hepatitis C virus and intrahepatic cholestasis of pregnancy (ICP) are well-known independent risk factors for adverse outcomes in pregnancy. In addition, it is well-established that there is an association between Hepatitis C and ICP. This study's objective was to describe the impact of having both Hepatitis C and ICP on maternal and obstetric outcomes compared to patients having either Hepatitis C or ICP. METHODS: We conducted a retrospective cohort study of the Nationwide Readmissions Database, an all-payor sample of discharges from approximately 60% of US hospitalizations. Deliveries at 24-42+ weeks between 10/2015 and 12/2020 were included. Diagnosis of Hepatitis C and ICP, and outcomes related to severe maternal morbidity were identified using International Classification of Disease-10 codes. Patients were categorized based on Hepatitis C and ICP status. Weighted logistic and negative binomial regression analyses were used to evaluate the association between Hepatitis C and ICP status and outcomes, adjusting for patient and hospital characteristics. The primary outcome was any severe maternal morbidity; secondary outcomes included acute respiratory distress syndrome, acute kidney injury, sepsis, gestational diabetes, cesarean delivery, preterm birth, and hospital length of stay. We modeled interaction terms between ICP and Hepatitis C to assess whether there was a greater or lesser effect from having both conditions on outcomes than we would expect from additive combination of the individual components (i.e., synergy or antagonism). RESULTS: A total of 10,040,850 deliveries between 24-42+ weeks were identified. Of these, 45,368 had Hepatitis C only; 84,582 had ICP only; and 1,967 had both Hepatitis C and ICP. Patients with both Hepatitis C and ICP had 1.5-fold higher odds of developing severe maternal morbidity compared to having neither. There was an also an increased odds of severe maternal morbidity in patients with both Hepatitis C and ICP compared to patients with only Hepatitis C or ICP. Having both was also associated with higher odds of preterm birth and length of stay compared to having only Hepatitis C, only ICP, or neither (preterm birth: aOR 5.09, 95% CI 4.87-5.33 vs. neither; length of stay: 46% mean increase, 95% CI 35-58% vs. neither). Associations were additive-no significant interactions between hepatitis C and cholestasis were found on rates of severe maternal morbidity, acute respiratory distress syndrome, acute kidney injury, sepsis, cesarean section, or preterm birth (all p>0.05), and was minimal for gestational diabetes and length of stay. CONCLUSION: Hepatitis C and ICP are independent, additive risk factors for adverse maternal and obstetric outcomes. Despite physiologic plausibility, no evidence of a synergistic effect of these two diagnoses on outcomes was noted. These data may be useful in counseling patients regarding their increased risk of adverse outcomes when ICP presents in association with Hepatitis C versus ICP alone.

BACKGROUND: There is large variation in recommended for postcesarean delivery venous thromboembolism (VTE) prophylaxis among commonly used guidelines. OBJECTIVES: The aim of the study is to estimate implications of adoption of VTE prevention guidelines for rates of receipt of VTE prophylactic therapy and VTE following cesarean delivery (CD). METHODS: We used administrative data from the 2015-2019 Nationalwide Readmissions Database to identify cesarean deliveries and rates of VTE stratified by risk factors, leading to different prophylactic strategies based on several national guidelines. We used input parameters from the literature to construct a hybrid decision tree/Markov model to project the implications of guideline adoption on VTE rates for the first 6 weeks following delivery. RESULTS: Adoption of either the 2011 American College of Obstetricians and Gynecologists or the 2018 American Society for Hematology guidelines would avert a relatively small proportion (5%) of VTE cases, albeit with little low-molecular-weight heparin (LMWH) use (87-115 doses per 1000 CD patients). The 2012 American College of Chest Physicians guidelines were predicted to be more effective at averting VTE (21.2% reduction) with more LMWH usage (570 doses per 1000 deliveries). The 2015 Royal College of Obstetricians and Gynaecologists guidelines and universal use of 6 weeks of LMWH would avert an even larger proportion of cases (37.4% and 57.6%, respectively), at the cost of much higher rates of LMWH utilization (7233 doses per 1000 patients and 38 648 doses per 1000 patients). CONCLUSIONS: Adoption of different guidelines would have notably varying implications for clinical practice and potential for alteration of the national rate of VTE following CD.

OBJECTIVE: This study aims to determine if pregnant patients with both pyelonephritis and anemia are at an increased risk of adverse maternal outcomes compared with those with pyelonephritis without anemia. STUDY DESIGN: We conducted a retrospective cohort study utilizing the Nationwide Readmissions Database (NRD). Patients with antepartum pyelonephritis-associated hospitalizations from October 2015 to December 2018 were included. International Classification of Diseases codes were used to identify pyelonephritis, anemia, maternal comorbidities, and severe maternal morbidities. The primary outcome was a composite of severe maternal morbidity, as defined by the Centers for Disease Control criteria. Univariate statistical methods, weighted to account for complex survey methods in the NRD, were used to assess for associations between anemia, baseline characteristics, and patient outcomes. Weighted logistic and Poisson regressions were used to assess for associations between anemia and outcomes, adjusting for clinical comorbidities and other confounding factors. RESULTS: In total, 29,296 pyelonephritis admissions were identified, corresponding to a weighted national estimate of 55,135 admissions. Of these, 11,798 (21.3%) were anemic. The rate of severe maternal morbidity was higher among anemic patients than nonanemic patients (27.8% vs. 8.9%, respectively, p < 0.001), and remained higher after adjustment (adjusted relative risk [aRR] 2.86 [95% confidence interval [CI]: 2.67, 3.06]). Rates of individual components of severe maternal morbidities, including acute respiratory distress syndrome (4.0% vs. 0.6%, aRR 3.97 [95% CI: 3.10, 5.08]), sepsis (22.5% vs. 7.9%, aRR 2.64 [95% CI: 2.45, 2.85]), shock (4.5% vs. 0.6%, aRR 5.48 [95% CI: 4.32, 6.95]), and acute renal failure (2.9% vs. 0.8%, aRR 1.99 [95% CI: 1.55, 2.55]) were all higher for anemic pyelonephritis. The mean length of stay was also longer (25% average increase, 95% CI: 22%, 28%). CONCLUSION: Among pregnant patients with pyelonephritis, those with anemia are at greater risk of severe maternal morbidity and longer hospital stay. KEY POINTS: · Anemia is associated with longer stays for pyelo.. · Anemic pyelo patients have increased morbidity.. · Anemic pyelo patients have increased sepsis risk..
RESUMO
BACKGROUND: Frozen section analysis of oral cancer specimens is ideal for assessing margin distances and depth of invasion (DOI); the latter impacts intraoperative decisions regarding elective neck dissection (END). Here, we show that intraoperative determination of worst pattern of invasion (WPOI), specifically WPOI-5, has a high level of accuracy. This relates to our demonstration herein that WPOI-5 predicts occult cervical metastases (OCM) for pT1 oral squamous carcinoma (OSC). METHODS: The presence of OCM was correlated with WPOI in 228 patients with primary T1/T2/cN0 OSC undergoing resection and END. Concordance between intraoperative and final pathology WPOI determination was assessed on 51 cases of OSC. RESULTS: WPOI-5 predicts OCM in pT1 patients, compared with WPOI-4/WPOI-3 (p < 0.0001). Most pT1 WPOI-5 tumors had DOI of 4-5 mm (24/59 or 40.7%). Only two pT1 WPOI-5 tumors had DOI < 4 mm (3.0 and 3.5 mm). If END were performed in this pT1 cohort for all WPOI-5 OSC patients regardless of DOI, OR all OSC patients with DOI ≥ 4 mm regardless of WPOI, then no OCM would be missed (p = 0.017, 100% sensitivity, 29% specificity, 77% positive predictive value, 23% negative predictive value). With respect to intraoperative WPOI-5 determination, the accuracy, sensitivity, and specificity was 92.16, 73.33, and 100.0%, respectively. CONCLUSIONS: DOI ≥ 4 mm is the dominant predictor of OCM. For the rare WPOI-5 OSC with DOI < 4 mm, it is reasonable to suggest that surgeons perform END. WPOI-5 may be accurately determined intraoperatively. As microscopic instruction is needed to accurately assess WPOI-5, a teaching link is included in this manuscript.

OBJECTIVE: The use of extracorporeal membrane oxygenation (ECMO) therapy has increased in the adult population. Studies from the H1N1 influenza pandemic suggest that ECMO deployment in pregnancy is associated with favorable outcomes. With increasing numbers of pregnant women affected by COVID-19 (coronavirus disease 2019) and potentially requiring this life-saving therapy, we sought to compare comorbidities, costs, and outcomes between pregnancy- and nonpregnancy-associated ECMO therapy among reproductive-aged female patients. STUDY DESIGN: We used the 2013 to 2019 National Readmissions Database. Diagnosis and procedural coding were used to identify ECMO deployment, potential indications, comorbid conditions, and pregnancy outcomes. The primary outcome was in-hospital mortality during the patient's initial ECMO stay. Secondary outcomes included length of stay and hospital charges/costs, occurrence of thromboembolic or bleeding complications during ECMO hospitalization, and mortality and readmissions up to 330 days following ECMO stay. Univariate and multivariate regression models were used to model the associations between pregnancy status and outcomes. RESULTS: The sample included 324 pregnancy-associated hospitalizations and 3,805 nonpregnancy-associated hospitalizations, corresponding to national estimates of 665 and 7,653 over the study period, respectively. Pregnancy-associated ECMO had lower incidence of in-hospital death (adjusted odds ratio [aOR]: 0.56, 95% confidence interval [CI]: 0.41-0.75) and bleeding complications (aOR: 0.67, 95% CI: 0.49-0.93). Length of stay was significantly shorter (adjusted rate ratio (aRR): 0.86, 95% CI: 0.77-0.96) and total hospital costs were less (aRR: 0.83, 95% CI: 0.75-0.93). Differences in the incidence of thromboembolic events (aOR: 1.04, 95% CI: 0.78-1.38) were not statistically significant. CONCLUSION: Pregnancy-associated ECMO therapy had lower incidence of in-hospital death, bleeding complications, total inpatient cost, and length of stay when compared with nonpregnancy-associated ECMO therapy without increased thromboembolic complications. Pregnancy-associated ECMO therapy should be offered to eligible patients. KEY POINTS: · Pregnancy-related ECMO use was compared with nonpregnant use.. · Outcomes were equal or favored pregnancy-related deployment.. · These data may be useful when considering ECMO use in pregnancy..
RESUMO
BACKGROUND: Low-risk papillary thyroid carcinoma (LR-PTC) can be managed by immediate surgery (IS) or active surveillance (AS). We compare the psychological impact of these treatments on patients with LR-PTC. METHODS: Psychological data were collected over 1 year, with assessments at the time of treatment decision (T1), at 6 months (T2) and 12 months (T3) follow-up. Assessments included 13 validated psychological tools. RESULTS: Of 27 enrolled patients, 20 chose AS and 7 chose IS. The average times to T2 and T3 were 5.7 and 11.3 months, respectively. For both groups, Impact of Events Scale scores significantly decreased (p = 0.001) at T2, and depressive/anxiety symptoms remained low. CONCLUSIONS: This study demonstrates the feasibility of assessing psychological outcomes among patients treated for LR-PTC. Further studies are needed to evaluate the impact of AS versus IS on quality of life and changes that patients experience over longer time periods following their treatment decision.

BACKGROUND: To compare rates of severe maternal morbidity (SMM) for pregnant patients with a cardiac diagnosis classified by the modified World Health Organization (mWHO) classification to those without a cardiac diagnosis. METHODS: This retrospective study using the 2015-2019 Nationwide Readmissions Database identified hospitalizations, comorbidities, and outcomes using diagnosis and procedure codes. The primary exposure was cardiac diagnosis, classified into low-risk (mWHO class I and II) and moderate-to-high-risk (mWHO class II/III, III, or IV). The primary outcome was SMM or death during the delivery hospitalization; secondary outcomes included cardiac-specific SMM during delivery hospitalizations and readmissions after the delivery hospitalization. RESULTS: A weighted national estimate of 14,995,122 delivery admissions was identified, including 46,541 (0.31%) with mWHO I-II diagnoses and 37,330 (0.25%) with mWHO II/III-IV diagnoses. Patients with mWHO II/III-IV diagnoses experienced SMM at the highest rates (22.8% vs 1.6% for no diagnosis; with adjusted relative risk (aRR) of 5.67 [95% CI: 5.36-6.00]). The risk of death was also highest for patients with mWHO II/III-IV diagnoses (0.3% vs <0.1% for no diagnosis; aRR 18.07 [95% CI: 12.25-26.66]). Elevated risk of SMM and death persisted to 11 months postpartum for those patients with mWHO II/III-IV diagnoses. CONCLUSIONS: In this nationwide database, SMM is highest among individuals with moderate-to-severe cardiac disease based on mWHO classification. This risk persists in the year postpartum. These results can be used to enhance pregnancy counseling.

Open-mouth deformity after mandibular resection presents a challenge for surgeons and patients, contributing to significant functional and cosmetic morbidity. We present an innovative surgical technique to prevent or correct open-mouth deformity. Tensor fascia lata slings were utilized in combination with maxillomandibular fixation to surgically correct or prevent open-mouth deformity in four patients who had previously undergone mandibulectomy or at the time of a contralateral mandibulectomy following prior hemimandibulectomy and reconstruction. Two patients achieved favorable outcomes, including oral competence and improved resting jaw position, while open-mouth deformity could not be corrected for one patient. Another patient remains in the early postoperative period following a secondary procedure to correct open-mouth deformity. Open-mouth deformity is a functional/aesthetic problem that has not been addressed in the literature. Use of tensor fascia lata slings to suspend the mandible is a novel approach to the surgical management of open-mouth deformity.

Tracheostomal stenosis following total laryngectomy presents a serious concern for surgeons and patients. Although various techniques correct tracheostomal stenosis, none address an existing tracheoesophageal puncture (TEP). We present an approach to repair tracheostomal stenosis, requiring tracheal resection, and preserve the TEP in a functional position needed for speech rehabilitation. A 62-year-old male with squamous carcinoma of the right true vocal fold underwent a salvage total laryngectomy with placement of a tracheoesophageal prosthesis. Seven years later, he developed tracheal narrowing. A tracheal resection and tracheoplasty were performed to manage the stenosis while maintaining the tracheoesophageal puncture. Six months postoperatively, the patient was well, with no stomal narrowing or trend toward collapse and uneventful healing. He achieved fluent voice easily with stomal occlusion. We present a novel surgical technique to correct for tracheostomal stenosis following total laryngectomy. Our technique allows for TEP preservation to facilitate speech rehabilitation postoperatively.

BACKGROUND: The impact of pre-existing ischemic heart disease (IHD) on pregnancy is incompletely described. OBJECTIVES: The purpose of this study was to compare adverse pregnancy outcomes between those with IHD and those with a cardiac diagnosis categorized by the modified World Health Organization classification and those without a cardiac diagnosis. METHODS: This retrospective study used the 2015 to 2018 Nationwide Readmissions Database. Delivery hospitalizations, comorbidities, and outcomes were identified using diagnosis and procedure codes. The exposure was isolated IHD. The primary outcome was severe maternal morbidity (SMM) or death during the delivery hospitalization, analyzed using adjusted relative risk (aRR) regression and weighted to account for the Nationwide Readmissions Database's complex survey methods. RESULTS: Of 11,556,136 delivery hospitalizations, 65,331 had another cardiac diagnosis, and 3,009 had IHD alone. Patients with IHD were older and had higher rates of diabetes and hypertension. In unadjusted analyses, adverse outcomes were more common among patients with IHD alone than among patients with no cardiac disease and modified World Health Organization class I-II disease. After adjustment, patients with IHD alone were associated with a higher risk of SMM or death (aRR: 1.51; 95% CI: 1.19-1.92) than those without a cardiac disease. In comparison, the aRR was 1.90 (95% CI: 1.76-2.06) for WHO class I-II diseases and 5.87 (95% CI: 5.49-6.27) for WHO II/III-IV diseases. Nontransfusion SMM or death (aRR: 1.60; 95% CI: 1.11-2.30) and cardiac SMM or death (aRR: 2.98; 95% CI: 1.75-5.08) were also higher for those with IHD. CONCLUSIONS: Isolated IHD in pregnancy is associated with worse outcomes than no cardiac disease during delivery hospitalization and approximates the risk associated with WHO I-II diagnoses.
RESUMO
BACKGROUND: In the Northern Hemisphere, influenza season typically starts in December and lasts through March. Pregnant people are at increased risk for influenza-related morbidity and mortality. Potentially, new viral strains or reduced provider suspicion leading to delayed diagnosis of late-season influenza could result in an increased risk of severe infection. OBJECTIVE: This study aimed to assess the incidence and morbidity associated with late-season influenza in pregnancy, compared with influenza in other seasons. STUDY DESIGN: This was a retrospective cohort study using the 2007-2018 National Inpatient Sample. Pregnant patients with discharge diagnosis codes consistent with influenza infection were compared on the basis of hospital admission quarter (quarter 1: October to December; quarter 2: January to March; quarter 3: April to June; quarter 4: July to September), with quarter 3 defined as "late-season." The primary outcome was the severe maternal morbidity composite defined by the Centers for Disease Control and Prevention. The secondary outcomes included sepsis, shock, acute renal failure, acute heart failure, temporary tracheostomy, and invasive mechanical ventilation. Associations between outcomes and quarter of infection were adjusted for age, hospitalization type (antepartum, delivery, or postpartum), and comorbid conditions using relative risk regression, weighted to reflect the National Inpatient Sample design. RESULTS: Of 7355 hospitalizations, corresponding to a weighted national estimate of 36,042, 2266 (30.8%) occurred in quarter 1, 4051 (55.0%) in quarter 2, 633 (8.6%) in quarter 3, and 405 (5.5%) in quarter 4. A nonsignificant trend toward higher rates of severe maternal morbidity was seen in the "late-season" compared with other quarters (13.9% [quarter 3] vs 10.5% [quarter 1] vs 12.1% [quarter 2] vs 13.6% [quarter 4]; P=.07). Moreover, sepsis was more common in patients with late-season influenza (8.0% [quarter 3] vs 4.8% [quarter 1] vs 5.8% [quarter 2] vs 5.9% [quarter 4]; P=.03). In the adjusted analyses, patients with late-season influenza had a 1.34 (95% confidence interval, 1.01-1.78) higher risk of severe maternal morbidity and 1.57 (95% confidence interval, 1.06-2.32) higher risk of sepsis than patients with influenza in quarter 1. CONCLUSION: Influenza infection between April and June, that is, late-season influenza, is associated with a higher risk of severe maternal morbidity and sepsis in pregnant patients. Obstetrical providers must continue to have awareness and suspicion for influenza infection during these months.

OBJECTIVE: Pyelonephritis is the most common nonobstetric cause for hospitalization during pregnancy. The maternal and obstetric complications associated with antepartum pyelonephritis are well described. However, it is not clear whether these risks extend into the postpartum period. The primary objective of this study was to describe the morbidity associated with postpartum pyelonephritis, by comparing the morbidity associated with pyelonephritis in the postpartum period to morbidity seen during pregnancy or delivery. METHODS: A retrospective cohort study was performed using the Nationwide Readmissions Database (NRD), an all-payor sample of discharges from approximately 60% of U.S. hospitalizations. Discharges between October 2015 and December 2018 were included. Maternity-associated hospitalizations, diagnosis of pyelonephritis, comorbid conditions, and incidence of severe maternal morbidity were identified using International Classification of Disease-10th Revision (ICD-10) diagnosis and procedure codes. Bivariate statistics, weighted to account for the complex survey methods in the NRD, were used to evaluate the association between antepartum, delivery, and postpartum hospital stays associated with pyelonephritis and maternal morbidity. Weighted regression models were used to evaluate the association between admission timing and maternal outcomes. RESULTS: A total of 32,850 pyelonephritis admissions were identified, corresponding to a national estimate of 61,837 admissions. Of these, 1,465 (2.4%) were postpartum, 55,056 (89.0%) were antepartum, and 5,317 (8.6%) involved a delivery stay. Rates of severe maternal morbidity were higher in the postpartum group than the antepartum or delivery hospitalization groups (59.5 vs. 12.9 and 15.8%, respectively, p < 0.001); when compared with antepartum hospitalizations, the adjusted relative risk for composite severe maternal morbidity for postpartum hospitalizations was 4.68 (95% confidence interval [CI]: 4.33, 5.05). Most of this difference was driven by rates of sepsis (53.2 vs. 11.0 vs. 10.9%). CONCLUSION: Though relatively uncommon, postpartum hospitalizations for pyelonephritis are associated with higher rates of severe maternal morbidity, driven by differential rates of sepsis, than are antepartum or delivery-associated hospitalizations.
RESUMO
BACKGROUND: Multiple guidelines regarding risk stratification for venous thromboembolism (VTE) incidence following cesarean delivery have been promulgated. OBJECTIVE: To estimate the percentage of cesarean delivery patients for which pharmacologic VTE would be recommended and subsequent incidence of VTE, based on several guidelines. PATIENTS/METHODS: This retrospective cohort study used data from the Nationwide Readmissions Database from October 2015 through December 2017. Diagnosis and procedure codes were used to identify patients undergoing cesarean delivery, incidence of VTE, and risk factors used to stratify risk in the existing guidelines. Time-to-event analysis was used to analyze data, stratified by risk categorization in 2011 American College of Obstetricians and Gynecologists (ACOG), 2012 American College of Chest Physicians (ACCP), 2015 Royal College of Obstetricians and Gynaecologists (RCOG), and 2018 American Society of Hematology (ASH) guidelines. RESULTS/CONCLUSIONS: In a cohort of 1 235 149 cesarean deliveries, VTE incidence was 2.1 per 1000 deliveries at 330 days following delivery (95% confidence interval: 2.0-2.2). Proportions of patients that would be recommended for pharmacologic prophylaxis ranged from 0.2% in 2018 ASH guidelines to 73.4% in 2015 RCOG criteria. Among groups considered at elevated risk for VTE for which pharmacologic prophylaxis would be recommended, VTE incidence varied from 35.2 per 1000 deliveries based on 2018 ASH criteria to 2.5 per 1000 in 2015 RCOG criteria. In a large cohort of cesarean deliveries in the United States, application of different risk stratification guidelines identified widely different proportions at risk of VTE following delivery, with implications for being categorized as having elevated risk.
