Techniques and Limitations of Gore Thoracoabdominal Multibranch Endoprosthesis (TAMBE) for Type 1A Endoleak After Failed Endovascular Aortic Repairs.

PURPOSE: Endovascular aortic aneurysm repair (EVAR) is the dominant treatment modality over open repair for abdominal aortic aneurysms. However, a higher rate of reinterventions remains the Achilles heel of EVAR. Although type 1A endoleak from proximal seal zone failure of EVAR remains one of the leading causes for reintervention, fenestrated branched devices suitable for proximal extension of failed EVAR are not widely available in the United States. Gore Thoracoabdominal Multibranch Endoprosthesis (TAMBE) is an off-the-shelf investigational device that provides supraceliac seal by incorporating 4 visceral and renal arteries via preloaded inner branches. CASE REPORT: In this article, we describe 2 cases of type 1A endoleak from previous EVAR devices repaired using TAMBE. Both cases were performed under the Food and Drug Administration (FDA) compassionate use exemption. Considerations on the case planning and implantation techniques of TAMBE specific to previous EVAR devices are reviewed. CONCLUSIONS: Gore TAMBE can be utilized to repair a type 1A endoleak of a previous infrarenal EVAR device. Greater supraceliac coverage necessary for TAMBE relative to the minimal seal zone should be considered when applying this device for a type 1A endoleak. CLINICAL IMPACT: This report demonstrates the feasibility of applying off-the-shelf TAMBE device to treat one of the most common failure modes of EVAR, type1A endoleak.

The Impact of Patient Sex on Outcomes after Endovascular Treatment of Aortoiliac Occlusive Disease.

BACKGROUND: The aim of this study was to explore the effect of patient sex on short-term and long-term outcomes after endovascular treatment for aortoiliac occlusive disease (AIOD). METHODS: A multicenter retrospective analysis was performed on all patients who underwent iliac artery stenting for AIOD across the 3 participating sites from October 1, 2018 to September 21, 2021. Preoperative clinical, operative, and postoperative data were collected on a dedicated database. Demographics and outcomes were compared between male and female patients and the probability of freedom from amputation and freedom from target lesion reintervention were estimated with the Kaplan-Meier method. RESULTS: Of 574 patients, 346 (60%) were male and 228 (40%) were female. Mean follow-up was 12 months. Female patients were significantly older (69.2 ± 10.2 years vs. 67.8 ± 8.9 years, P = 0.025) and more likely to have Trans-Atlantic Inter-Society Consensus II D disease (P = 0.003). The female cohort had significantly less coronary artery disease (40% vs. 50%, P = 0.013), coronary stenting (14% vs. 21%, P = 0.039), and coronary artery bypass grafting (13% vs. 25%, P < 0.001) than the male cohort, as well as less statin use (69% vs. 80%, P = 0.004). There were no differences in stent type, concomitant open surgery, intraoperative events, or hospital length of stay. For 30-day postoperative complications, female patients had a significantly higher rate of thrombotic acute limb ischemia (2% vs. 0%, P = 0.01), while male patients had a higher rate of amputation (4% vs. 9%, P = 0.048). On mid-term outcomes, there was no difference in freedom from amputation or target lesion reintervention between male and female patients (P = 0.14 and P = 0.32, respectively). CONCLUSIONS: Female patients had lower incidence of cardiovascular risk factors but presented with higher Trans-Atlantic Inter-Society Consensus II classification and had higher rates of 30-day thrombotic acute limb ischemia. Male patients were more likely to require amputation within 30 days. Despite no differences in the mid-term, these short-term findings suggest that patient sex may be a relevant consideration in postoperative management and surveillance after endovascular treatment of AIOD.

Commonly performed pelvic binder modifications for femoral access may hinder binder efficacy.

BACKGROUND: Pelvic fractures are common and potentially life-threatening. Pelvic circumferential compression devices (PCCD) can temporize hemorrhage, but more invasive strategies that involve femoral access may be necessary for definitive treatment. The aim of our study was to evaluate the efficacy of PCCDs reducing open book pelvic fractures when utilizing commonly described modifications and placement adjustments that allow for access to the femoral vasculature. METHODS: Open book pelvic fractures were created in adult cadavers. Three commercially available PCCDs were used to reduce fractures. The binders were properly placed, moved caudally, or moved cranially and modified. Fracture reduction rates were then recorded. RESULTS: The pelvic fracture was completely reduced with every PCCD tested when properly placed. Reduction rates decreased with improper placement and modifications. CONCLUSION: Modifying PCCD placement to allow femoral access decreased the effectiveness of these devices Clinicians should be aware of this possibility when caring for critically injured trauma patients with pelvic fractures.

Length of stay and trauma center finances: A disparity of payer source at a Level I trauma center.

BACKGROUND: In an effort to reduce costs, hospitals focus efforts on reducing length of stay (LOS) and often benchmark LOS against the geometric LOS (GMLOS) as predicted by the assigned diagnosis-related group (DRG) used by the Centers for Medicare and Medicaid Services. The objective of this cross-sectional study was to evaluate the impact of exceeding GMLOS on hospital profit/loss with respect to payer source. METHODS: Contribution margin for each insured patient admitted to a Level I trauma center between July 1, 2016, and June 30, 2019, was determined. Age, ethnicity, race, DRG weight, DRG version, injury severity, intensive care unit admission status, mechanical ventilation, payer, exceeding GMLOS, and the interaction between payer and exceeding the GMLOS were regressed on contribution margin to determine significant predictors of positive contribution margin. RESULTS: Among 2,449 insured trauma patients, the distribution of payers was Medicaid (54.6%), Medicare (24.0%), and commercial (21.4%). Thirty-five percent (n = 867) of patient LOS exceeded GMLOS. Exceeding GMLOS by 10 or more days was significantly more likely for Medicaid and Medicare patients in stepwise fashion (commercial, 2.7%; Medicaid, 4.5%; Medicare, 6.0%; p = 0.030). Median contribution margin was positive for commercially insured patients ($16,913) and negative for Medicaid (-$8,979) and Medicare (-$2,145) patients. Adjusted multivariate modeling demonstrated that when exceeding GMLOS, Medicare and Medicaid cases were less likely than commercial payers to have a positive contribution margin (p < 0.001 and p < 0.001). CONCLUSION: Government-insured patients, despite having a payer source, are a financial burden to a trauma center. Excess LOS among government insured patients, but not the commercially insured, exacerbates financial loss. A shift toward a greater proportion of government insured patients may result in a significant fiscal liability for a trauma center. LEVEL OF EVIDENCE: Economic and Value-Based Evaluation, Level III.

Early Psychiatric Consultation Is Associated With Decreased Cost and Length of Stay in the Patient Population at a Level I Trauma Center.

Introduction Psychiatric illness impacts nearly one-quarter of the US population. Few studies have evaluated the impact of psychiatric illness on in-hospital trauma patient care. In this study, we conducted a retrospective cohort study to evaluate hospital resource utilization for trauma patients with comorbid psychiatric illnesses. Methodology Trauma patients admitted to a level I center over a one-year period were included in the study. Patients were categorized into one of three groups: (1) no psychiatric history or in-hospital psychiatric service consultation; (2) psychiatric history but no psychiatric service consultation; and (3) psychiatric service consultation. Time to psychiatric service consultation was calculated and considered early if occurring on the day of or the day following admission. Patient demographics, outcomes, and resource utilization were compared between the three groups. Results A total of 1,807 patients were included in the study (n = 1,204, 66.6% no psychiatric condition; n = 508, 28.1% psychiatric condition without in-hospital psychiatric service consultation; and n = 95, 5.3% in-hospital psychiatric service consultation). Patients requiring psychiatric service consultation were the youngest (P < .001), with the highest injury severity (P = .024), the longest hospital length of stay (P < .001), and the highest median hospital cost (P < .001). Early psychiatric service consultation was associated with an average saving in-hospital length of stay of 2.9 days (P = .021) and an average hospital cost saving of $7,525 (P = .046). Conclusion One-third of our trauma population had an existing psychiatric diagnosis or required psychiatric service consultation. Resource utilization was higher for patients requiring consultation. Early consultation was associated with a savings of hospital length of stay and cost.
