Abstract
OBJECTIVE Whether socioeconomic status (SES) is associated with health outcomes in patients with acute limb ischemia (ALI) is largely unknown. We aimed to determine whether SES is associated with worse presentations and outcomes for patients with ALI. METHODS We performed a retrospective medical record review of patients who presented with ALI between April 2016 and October 2020 at a single tertiary care center. SES was quantified using individual variables (median household income, level of education, and employment) and a composite endpoint, the neighborhood deprivation index (NDI). The NDI is a standardized and reproducible index that uses census tract data (higher number indicates lower SES status). The NDI summarizes 8 domains of socioeconomic deprivation. ALI severity was categorized using the Rutherford classification. The association between SES and the severity of ALI at presentation and between SES and other health outcomes were analyzed using bivariate analysis of variance, independent t test, and multivariate logistic regression. RESULTS During the study period, 278 patients were treated for ALI, of whom 211 had complete SES data available. The mean age was 64 years, 55% were men, and 57% were White. The Rutherford classification of disease severity was grade 1, 2a, 2b, and 3 for 6%, 54%, 32%, and 8% of patients, respectively. Patients with a low SES status per the NDI were more likely to have a history of peripheral arterial disease and chronic kidney disease at presentation. The ALI etiology (thrombotic vs embolic) was not associated with SES. No significant differences were seen between SES and the severity of ALI at presentation (p = 0.96) or the treatment modality (p = 0.80). No associations between SES and 30-day or 1-year mortality were observed (mean NDI, 0.15 vs 0.26, p = 0.58, and 0.20 vs 0.26, p = 0.71, respectively) or between SES and 30-day or 1-year limb loss (mean NDI, 0.06 vs 0.30, p = 0.18, and 0.1 vs 0.32, p = 0.17, respectively). Lower SES (higher NDI) was associated with increased 30-day readmission (mean NDI, 0.49 vs 0.15, p = 0.021). However, this association was not significant on multivariate analysis (odds ratio 1.4, 95% CI 0.9-2.1, p = 0.06). CONCLUSIONS SES was not associated with the severity of ALI at patient presentation. Although SES was associated with the presence of peripheral arterial disease and chronic kidney disease at presentation, SES was not a predictor of short-term or 1-year limb loss and mortality. Overall, ALI presentation and treatment outcomes were independent of SES.

Left subclavian artery revascularization is associated with less neurologic injury after endovascular repair of acute type B aortic dissection. J Vasc Surg 2023; 78:1170-1179.e2. [PMID: 37524152 DOI: 10.1016/j.jvs.2023.07.051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 07/16/2023] [Accepted: 07/22/2023] [Indexed: 08/02/2023]
Abstract
OBJECTIVE The aim of this study was to analyze patients with acute type B aortic dissection (aTBAD) requiring thoracic endovascular aortic repair (TEVAR) with left subclavian artery (LSA) coverage to determine whether LSA revascularization decreased the risk of neurologic complications. METHODS The national Vascular Quality Initiative TEVAR module was queried for all procedures performed between 2014 and 2021. Patients presenting with aortic aneurysms or aortic ruptures were excluded from the analysis. Patients were divided into two groups according to whether their LSA was revascularized (prior to or during TEVAR) or not. Univariate followed by multivariate analysis was used to account for possible confounders and evaluate the association of LSA revascularization with the primary outcome of neurologic injury (stroke or spinal cord ischemia). RESULTS Among patients who had TEVAR for aTBAD, 501 patients had the LSA covered. The LSA was revascularized prior to or concomitant with TEVAR in 28% of these patients (n = 139). Average age was 57 years, and 73% (n = 366) were male. Neurologic injury developed in 88 patients (18%). On univariate analysis, patients who had their LSA revascularized were significantly less likely to develop neurologic injury (10% vs 20%; P < .01). This association persisted after accounting for potential confounders (odds ratio, 0.4; P = .02). No significant difference was seen when comparing 30-day or 1-year mortality between patients who had LSA revascularization and those who did not. Follow-up averaged 1.9 years (range, 0-8.1 years). Long-term survival did not differ between the two groups on Kaplan-Meier analysis. CONCLUSIONS In this study of patients with aTBAD who underwent LSA coverage during TEVAR, the addition of a LSA revascularization procedure was associated with a significantly lower incidence of neurological injury including spinal cord ischemia and/or stroke.

Necessity, Role, and Outcomes of Fasciotomy in Patients with Acute Limb Ischemia. Ann Vasc Surg 2023:S0890-5096(23)00244-3. [PMID: 37142120 DOI: 10.1016/j.avsg.2023.04.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 04/05/2023] [Accepted: 04/20/2023] [Indexed: 05/06/2023]
Abstract
BACKGROUND The incidence of compartment syndrome in patients with acute lower limb ischemia (ALLI) and the effects of fasciotomy on outcomes are largely undefined. This study aimed to define the incidence of compartment syndrome in patients with ALLI and to examine whether different fasciotomy strategies are associated with specific patient outcomes. METHODS A single center retrospective study of patients who had ALLI between April 2016 and October 2020 at a tertiary care center. Patients were categorized into groups as having received early and late therapeutic fasciotomy (TF), early prophylactic fasciotomy (PF), early exploratory fasciotomy, and no fasciotomy. Primary outcome was 30-day amputation rate. Secondary outcomes were 30-day and 1-year mortality, 1-year amputation rate, and length of stay. Groups were compared using descriptive statistics to assess the association of fasciotomy approach with outcomes. RESULTS During the study period, 266 patients were treated for ALLI, and 62 patients (23%) underwent 66 fasciotomies. A total of 41 TF, 23 PF, and 2 exploratory fasciotomies were done. There were 58 early fasciotomies performed (88% of 66 limbs): 33 (57%) early TF, 23 (40%) PF, and 2 (3%) exploratory. There were 8 patients who developed compartment syndrome after their revascularization operation and received delayed TF (12% of 66 limbs). The total number of TF was 41, which was 15% of all ALLI patients. The mean ± SD time to fasciotomy closure was 6.7 ± 5.7 days, which did not differ between PF and TF groups. Significantly more patients in the TF had an amputation at 30 days (11 [29%] vs 1 [5%]; P = 0.03) and at 1 year (6 [18%] vs 2 [9%]; P = 0.02) than those in the PF group. Length of stay was increased in both TF (16 days) and PF (19 days) patients compared to non-fasciotomy patients (10 days; P < 0.01) but did not differ between the 2 fasciotomy groups (P = 0.4). Thirty-day limb loss was highest in patients who underwent early TF (10/33, 33%), intermediate in those with delayed TF (1/8, 13%), and lowest in PF (1/23, 5%; P = 0.03). CONCLUSIONS Approximately 15% of patients with ALLI in our cohort required a TF for compartment syndrome. Close postoperative monitoring of ALLI patients who did not undergo early fasciotomy did detect delayed CS; however, this approach did not prevent limb loss. To optimize limb salvage, physicians treating patients with ALLI should be experienced in how to recognize and treat compartment syndrome.

Abstract
OBJECTIVES By analyzing national Vascular Quality Initiative (VQI) data for patients undergoing open infrarenal abdominal aortic aneurysms (AAA) repair, we sought to better characterize the effects of different suprarenal clamping positions on postoperative outcomes. METHODS We performed a retrospective analysis of a prospectively collected national VQI database for all open infrarenal AAA repairs performed between 2003 and 2017. Patients were initially divided into proximal (above 1 renal, above 2 renals, and supraceliac) and infrarenal clamp groups. Patients were then subdivided into those who underwent surgery between 2003-2010 and those who had surgery between 2011-2017. Univariate followed by multivariate analyses were done to compare the baseline characteristics, preoperative, intraoperative, and postoperative outcomes between the two groups. RESULTS During the study period, 9068 open AAA repairs were recorded in the VQI; of these, 5043 met the inclusion criteria. Aortic clamp level was infrarenal in 59% (N = 2975), above 1 renal in 15% (N = 735), above both renals in 21% (N = 1053), and supraceliac in 5% (N = 280). The average age was 69 years, and males comprised 73% (N = 3701) of the cohort. The overall 30-day mortality for the entire study group was 2.7%. On univariate analysis, patients who underwent proximal clamping had significantly higher 30-day mortality than those undergoing infrarenal clamping (3.7 vs 2.0%, p < 0.001). After adjusting for preoperative and intraoperative variables, this difference became nonsignificant. On multivariate analysis, clamping above both renals or the celiac artery was associated with an increased occurrence of postoperative myocardial infarction (odds ratio = 1.44, p = 0.037 and odds ratio = 1.78, p = 0.023, respectively). All proximal clamp positions were associated with a significant increase in the incidence of AKI and renal failure requiring dialysis. There was no significant difference when looking at overall survival times comparing the suprarenal and infrarenal clamp position groups (p = 0.1). Patients who underwent surgery in the latter half of the study period had longer intraoperative renal ischemia time, increased in estimated blood loss, and longer total procedure time. CONCLUSIONS Suprarenal clamping, at any level, was associated with an increased risk of AKI and renal replacement therapy. Clamping above both renal and celiac arteries was associated with increased cardiac morbidity. Perioperative and long-term mortality was unaffected by clamp level. Patients operating in the latter half of the study had increased estimated blood loss, renal ischemia time, and operative time, which may reflect decreased training in open AAA repair. During open AAA repair, the proximal clamp site should be chosen based on anatomic considerations and not a perceived perioperative mortality benefit. Proximal aortic clamping should always be performed at the safest, distal-most level to reduce cardiac morbidity and the risk of postoperative dialysis.

Abstract
PURPOSE Preoperative anemia is associated with adverse outcomes after cardiac and noncardiac surgeries, but outcomes after an endovascular peripheral vascular intervention (PVI) are not well established. We aimed to assess the association of preoperative anemia with 30 day death, hospital length of stay (LOS), and overall (long term) survival in patients undergoing an endovascular PVI for peripheral artery disease. MATERIALS AND METHODS In this retrospective, cohort study in the United States and Canada, we queried the national Vascular Quality Initiative database for all endovascular PVIs performed between 2010 and 2019, and outcomes were correlated with patients' hemoglobin (Hb) levels. Anemia was classified as mild (Hb=10-13 g/dL for men and 10-12 g/dL for women), moderate (Hb=8-9.9 g/dL), and severe (Hb<8 g/dL). RESULTS A total of 79 707 adult patients who met study criteria underwent endovascular PVI. The mean age was 68 years, and 59% of patients were male. Anemia was documented in 38 543 patients (48%) and was mild in 27 435 (71%), moderate in 9783 (25%), and severe in 1325 (4%). The median follow-up duration was 4 years (range, 1.25-5.78 years). On univariate analysis, 30 day mortality, total LOS, and overall survival were significantly associated with the level of preoperative anemia. These associations persisted in the multivariate models. Kaplan-Meier survival analysis demonstrated an association of death with degree of anemia (p<0.001). CONCLUSION The presence and degree of preoperative anemia were independently associated with increased 30 day mortality and LOS and decreased overall survival for patients with peripheral artery disease who had undergone endovascular PVI. CLINICAL IMPACT The findings from this study have many implications for how to approach vascular surgery in patients with variable hemoglobin levels. Our findings will strengthen our ability to conduct accurate preoperative risk stratification for patients undergoing peripheral vascular interventions. This may also mitigate healthcare expenditures if findings are applied in a way that can lower patient length of postoperative stay while also maintaining quality of care and patient safety. Our results will also serve as guidance for clinical trials, and future prospective trials should evaluate the effect of preoperative optimization of hemoglobin as a potentially modifiable risk factor for outcomes.

Abstract
Objective: To analyze whether the rate of lower extremity (LE) ischemia is higher on the ipsilateral side after kidney transplantation. Methods: Our institutional transplant database was retrospectively queried for all patients who received a kidney transplant and underwent subsequent LE revascularization or major limb amputations between January 2004 and July 2020. The one-sample binomial test was used to test whether the LE ipsilateral to the transplanted kidney was at higher risk of peripheral arterial disease (PAD) complications necessitating intervention (major amputation or revascularization). Results: There were 1,964 patients who received a kidney transplant during the study period. Of these, 51 patients (3%) had subsequent LE arterial revascularizations or major amputations. The mean age was 58 ± 10 years, and 37 patients (73%) were male. A total of 33 patients had ipsilateral LE vascular interventions (26 major amputations and seven revascularizations) while 18 patients had contralateral vascular interventions (14 major amputations and four revascularizations) (P = 0.049). The average interval between transplantation and subsequent vascular intervention was 52 months for the ipsilateral intervention group and 41 months for the contralateral intervention group (P = 0.33). Conclusions: In patients who received kidney transplantation and required subsequent LE surgical intervention, we observed an association between the side of transplantation and the risk of future ipsilateral LE arterial insufficiency. Further studies are needed to determine the etiology of this association.

Abstract
Objective: To investigate the incidence and characteristics of deep vein thrombosis (DVT) in kidney transplantation recipients and analyze whether the anatomical side of DVT was associated with the side of the transplanted organ. Methods: A single-center retrospective medical record review of patients who received a kidney transplant between January 2004 and July 2019 and who subsequently developed DVT. Only patients who received unilateral kidney transplants were included in the study. Patients who underwent concomitant pancreatic transplants, bilateral kidney transplants, or repeat procedures were excluded. Results: Of the 2449 kidney transplants performed during the study period, 1482 were included in the analysis (948 men [64%]; mean age 61 years). Of 606 duplex ultrasound tests, 115 results confirmed the presence of DVT. The incidence of symptomatic DVT was 4.7%. The most common time of DVT diagnosis was within four weeks after transplantation. Type 2 diabetes, heart failure, acute myocardial infarction, sepsis, chronic obstructive pulmonary disease/abnormal pulmonary function, and being confined to bed were associated with DVT after kidney transplant (all P < 0.05). Patients with ultrasound-confirmed DVT had higher mean Caprini scores than patients with negative duplex ultrasounds (P < 0.5). Approximately 53% of transplant patients with ultrasound-confirmed DVT had a 1:1 correlation of transplant side to the side of DVT. Cohen kappa statistic 0.03 indicated no correlation between the side of DVT and the side of transplant. Conclusions: The incidence of DVT after kidney transplant was lower than the incidence reported in the literature. Being confined to a bed may be a risk factor for DVT after transplant surgery. Kidney transplant recipients who had a positive duplex ultrasound had higher Caprini risk assessment scores than transplant recipients who had negative duplex ultrasounds. There was no correlation between the side of the DVT and the side of the transplant.

Abstract
572 Background: Stereotactic MRI -guided adaptive radiation therapy (SMART) is being investigated for enhanced efficacy in locally advanced, borderline resectable and medically inoperable pancreatic cancer. Traditionally, conventionally fractioned chemoradiation (EBRT) has been used for operable patients. We sought to evaluate whether there would be differences in surgical complications and outcomes in the 30- and 90- day postoperative period in patients who received either neoadjuvant EBRT or SMART followed by definitive surgery. Methods: A retrospective single-center analysis of patients with either resectable, borderline resectable or locally advanced tumors of the pancreas or duodenum, treated with neoadjuvant radiation and surgical management between 2014 and 2021 was performed. Patient demographics and post-surgical complications were collected and stratified according to both treatment arms. The International Study Group of Pancreatic Surgery (ISGPS) classifications were used to define and grade postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE) and postpancreatectomy hemorrhage (PPH). A univariate analysis was done followed by a multivariate analysis. Results: Among the 65 patients (mean age 62.6 years, 46% female) who underwent definitive surgical intervention, 44 (67.7%) received EBRT, and 21 (32.3%) received SMART. Baseline characteristics including age, sex, race, ASA, and Charlson comorbidity index (CCI) scores were found to be similar. On univariate analysis, PPH was significantly higher in SMART (OR, 6.6; 95% CI, 1.2 to 37.3; p = 0.034). After adjusting for confounders on multivariate analysis, it appears there is a trend towards higher PPH in the SMART cohort ( p = 0.052). Conclusions: Neoadjuvant SMART followed by definitive surgery is not associated with worse outcomes in the 30- and 90- day postoperative period vs. neoadjuvant EBRT. Although there was a trend towards PPH on multivariate analysis, further discussion is warranted involving vascular resection, vascular stents and anticoagulation.[Table: see text]

Abstract
OBJECTIVES The association between socioeconomic status (SES) and chronic venous insufficiency has not been rigorously studied. This study aimed to determine the influence of SES on the clinical stage of patients presenting for chronic venous disease therapy. METHODS We performed a retrospective study of a prospectively collected data from the Vascular Quality Initiative Varicose Vein Registry at our tertiary referral center. Medical records of patients who underwent therapy for chronic venous disease between January 2015 and June 2019 were queried. SES was quantified using the neighborhood deprivation index (NDI), which summarizes 8 domains of socioeconomic deprivation and is based on census tract data derived from the patients' addresses at the time of the treatment. High NDI scores correspond with lower SES. The association between SES and severity of vein disease at presentation was assessed with bivariate analysis of variance and linear regression analysis. RESULTS A total of 449 patients with complete SES and clinical-etiology-anatomy-pathophysiology (CEAP) class data were included in the study. The mean age was 58 years, 67% were female, and 60% were White. CEAP classes were distributed as follows C2, 22%; C3, 50%; C4, 15%; C5, 5%; and C6, 8%. Patients with lower SES (higher NDI score) tended to have a higher CEAP class at presentation (P < 0.05). SES was not associated with history of deep venous thrombosis, use of compression therapy, or venous clinical severity score. CONCLUSIONS At our institution, patients with more advanced venous disease tended to belong to a lower SES group. This may reflect that patients with a lower SES have a longer time to presentation due to delay in seeking medical help for venous disease.

Effect of Intubation Timing on the Outcome of Patients With Severe Respiratory Distress Secondary to COVID-19 Pneumonia. Cureus 2021; 13:e19620.

Abstract
Background The optimal timing of intubation for critically ill patients with severe respiratory illness remains controversial among healthcare providers. The coronavirus disease 2019 (COVID-19) pandemic has raised even more questions about when to implement this life-saving therapy. While one group of providers prefers early intubation for patients with respiratory distress because these patients may deteriorate rapidly without it, other providers believe that intubation should be delayed or avoided because of its associated risks including worse outcomes. Research question Our objective was to assess whether the timing of intubation in patients with severe COVID-19 pneumonia was associated with differences in mortality or other outcomes. Study design and methods This was a single-center retrospective observational cohort study. We analyzed outcomes of patients who were intubated secondary to COVID-19 pneumonia between March 13, 2020, and December 12, 2020, at Henry Ford Hospital in Detroit, Michigan. Patients were categorized into two groups: early intubated (intubated within 24 hours of the onset of severe respiratory distress) and late intubated (intubated after 24 hours of the onset of severe respiratory distress). Demographics, comorbidities, respiratory rate oxygenation (ROX) index, sequential organ failure assessment (SOFA) score, and treatment received were compared between groups. The primary outcome was mortality. Secondary outcomes were ventilation time, intensive care unit stay, hospital length of stay, and discharge disposition. Post hoc and Kaplan-Meier survival analyses were performed. Results A total of 110 patients were included: 55 early intubated and 55 late intubated. We did not observe a significant difference in overall mortality between the early intubated (43%) and the late intubated groups (53%) (p = 0.34). There was no statistically significant difference in patients' baseline characteristics including SOFA scores (the early intubation group had a mean score of 7.5 compared to 6.7 in the late intubation group). Based on the ROX index, the early intubation group had significantly more patients with a reduced risk of intubation (45%) than the late group (27%) (p = 0.029). The early intubation group was treated with a high-flow nasal cannula at a significantly lower rate (47%) than the late intubation group (83%) (p < 0.001). Significant differences in patient baseline characteristics, treatment received, and other outcomes were not observed. Post hoc analysis adjusting for SOFA score between 0 and 9 revealed significantly higher mortality in the late intubation group (49%) than in the early intubation group (26%) (p = 0.03). Patients in the 0 to 9 SOFA group who were intubated later had 2.7 times the odds of dying during hospital admission compared to patients who were intubated early (CI, 1.09-6.67). Interpretation The timing of intubation for patients with severe COVID-19 pneumonia was not significantly associated with overall mortality or other patient outcomes. However, within the subgroup of patients with SOFA scores of 9 or lower at the time of intubation, patients intubated after 24 hours of the onset of respiratory distress had a higher risk of death than those who were intubated within 24 hours of respiratory distress. Thus, patients with COVID-19 pneumonia who are not at a high level of organ dysfunction may benefit from early mechanical ventilation.

Abstract
To supplement preexisting wellness programming for the surgery clerkship, a faculty surgeon at Vanderbilt initiated Fireside Chats (FC) in 2015. Inspired by Franklin Roosevelt’s Depression-era radio broadcasts, FC features small group sizes, off-campus excursions, and a reimagining of the mentor–mentee relationship that eschews hierarchy in favor of deep, mutualistic connections in both personal and professional domains. Here we describe the rationale and implementation of FC and present survey data that demonstrate the warm reception of FC and its efficacy in stewarding the mental health of medical students. Moreover, unlike large group activities such as “learning communities,” FC continues to meet in-person during COVID-19 and preserves social engagement opportunities that may alleviate pandemic-induced isolation and distress.
