RESUMEN
OBJECTIVE: Vascular Ehlers-Danlos syndrome (VEDS) is rare and associated with arteriopathies. The aim of this study is to investigate the presentation, operative interventions, and outcomes of splenic arterial pathology in a population of more than 1500 individuals with genetically confirmed VEDS due to pathogenic COL3A1 variants. METHODS: Cross-sectional analysis of 1547 individuals was performed. The data were assembled by harmonizing data from three overlapping cohorts with genetically confirmed VEDS: the VEDS Collaborative Natural History Study (N = 242), a single-center cohort (N = 75), and the University of Washington Collagen Diagnostic Lab cohort (N = 1231). Duplicates were identified and removed. Patients were selected for analysis if they had splenic artery aneurysm (SAA), pseudoaneurysm, dissection, thrombosis, or rupture. Demographics, COL3A1 variants, interventions, and outcomes were analyzed. Comparisons by splenic artery rupture were made. RESULTS: A total of 88 patients presented between 1992 and 2021 with splenic artery pathology (5.7% of the cohort; mean age at diagnosis, 37 ± 11.1 years; 50% male). One-third were diagnosed with VEDS prior to the splenic artery pathology diagnosis, and 17% were diagnosed post-mortem. Most had a positive family history (61%). Most had COL3A1 variants associated with minimal normal collagen production (71.6%). Median follow up was 8.5 years (interquartile range, 0.9-14.7 years). Initial presentation was rupture in 47% of the cases. Splenic artery rupture overall was 51% (n = 45), including four cases of splenic rupture. There were no major differences in VEDS-related manifestations or COL3A1 variant type by rupture status. SAA was noted in 39% of the cases. Only 12 patients had splenic artery diameter documented in 12 cases with a median diameter of 12 mm (interquartile range, 10.3-19.3 mm). A total of 34 patients (38.6%) underwent 40 splenic arterial interventions: 21 open surgical, 18 embolization, and one unknown procedure. More than one splenic artery intervention was performed in five cases (14.7%). Open repair complications included arteriovenous fistula (n = 1), intestinal or pancreatic injury (n = 1 each), and four intraoperative deaths. There were no deaths or access site complications related to splenic artery embolization. Four patients (23.5%) developed a new SAA in the remaining splenic artery post embolization. All-cause mortality was 35% (n = 31), including 22 related to a ruptured splenic artery. CONCLUSIONS: Splenic arteriopathy in VEDS is associated with variants that affect the structure and secretion of type III collagen and frequently present with rupture. Rupture and open repair are associated with high morbidity and mortality, whereas embolization is associated with favorable outcomes. Suggest repair considerations at SAA diameter of 15 mm. Long-term follow-up is indicated as secondary splenic arteriopathy can occur.

BACKGROUND: Popliteal Artery Entrapment Syndrome (PAES) is a rare clinical entity without a standardized algorithm for diagnosis and treatment. The objective of this study was to evaluate the clinical outcomes of a unique diagnostic and management algorithm for patients with PAES managed at a quaternary referral center. METHODS: We retrospectively reviewed patients diagnosed with PAES at a single institution between 2013 and 2021. Demographics, physical exam findings, noninvasive imaging results, and angiographic images were assessed to validate a diagnostic and management algorithm (Figure 1). Surgical findings, operative technique, post-operative complications, and symptomatic improvement were assessed to validate this clinical algorithm. RESULTS: There were 35 extremities in 23 patients treated for PAES (Table I). The mean age was 28, and 82.6% of patients were female. Physical exam revealed a decrement in pedal pulse with provocative maneuvers in 90% of treated limbs. Noninvasive studies to include treadmill exercise testing revealed a mean Ankle-brachial indices (ABI) drop of 0.28 and positional duplex demonstrated that the mean peak systolic velocity (PSV) in the popliteal artery was 78 cm/sec at rest which increased to 175 cm/sec with provocation. Diagnostic arteriography was performed in all patients and revealed awell-developed geniculate and sural collaterals in 100% of the treated limbs and complete effacement of the popliteal artery with active provocative maneuvers in all treated limbs (Figure 2). Surgical exposure was performed via a posterior approach and intraoperative completion duplex was performed in all cases. Type III PAES was discovered in 89% of cases. Arterial reconstruction was required in 2 patients who presented with an occluded popliteal artery. All but one patient was discharged on post-operative day one. Wound complications occurred in 4 limbs (3 patients) and included seroma and hypertrophic scarring. All patients experienced symptomatic relief with a median follow-up of 4 months. CONCLUSIONS: We reported 100% technical and clinical success in patients with PAES diagnosed and managed using our clinical algorithm. Cross-sectional imaging is not necessary for the diagnosis. Dynamic angiography confirms the diagnosis and intraoperative duplex is essential for successful clinical outcome by confirming complete release of the popliteal artery.

The ever-increasing diversity of the U.S. population has resulted in a challenge to a vascular surgery workforce that does not represent the national demographics. Educational institutions, medical organizations, and medical agencies, through initiatives and programs, have attempted to increase the number of underrepresented minorities, with, however, only modest changes during the past 30 years. Several obstacles have been identified, some of which include racism, issues of finances, lack of mentors and scholarly activities, and inequity in promotion. In the present study, we have reviewed the reported data addressing these concerns and provided guidance toward the amelioration of these issues with the hope of constructive change toward encouraging a diverse vascular surgery workforce.

The use of social media (SoMe) in medicine has demonstrated the ability to advance networking among clinicians and other healthcare staff, disseminate research, increase access to up-to-date information, and inform and engage medical trainees and the public at-large. With increasing SoMe use by vascular surgeons and other vascular specialists, it is important to uphold core tenets of our commitment to our patients by protecting their privacy, encouraging appropriate consent and use of any patient-related imagery, and disclosing relevant conflicts of interest. Additionally, we recognize the potential for negative interactions online regarding differing opinions on optimal treatment options for patients. The Society for Vascular Surgery (SVS) is committed to supporting appropriate and effective use of SoMe content that is honest, well-informed, and accurate. The Young Surgeons Committee of the SVS convened a diverse writing group of SVS members to help guide novice as well as veteran SoMe users on best practices for advancing medical knowledge-sharing in an online environment. These recommendations are presented here with the goal of elevating patient privacy and physician transparency, while also offering support and resources for infrequent SoMe users to increase their engagement with each other in new, virtual formats.

BACKGROUND: The association of procedure volume and improved outcomes has been established with infrequently performed elective operations. However, effect of trauma center volume on outcomes in emergency surgery has not been defined. We hypothesized that high volume centers (HVC) would provide better outcomes for operative major vascular injuries (MVI) than low volume centers (LVC). METHODS: The NTDB was queried from 2010 to 2014. Patients with MVI were identified and HVC were compared to LVC. HVC were defined as >480 patients per year with ISS≥15. RESULTS: There were 37,125 patients with MVI, with 16,461 (44.3%) managed operatively. Of these, 15,965 (97%) underwent surgery at HVC and 496 (3%) at LVC. There was no difference in shunt utilization, however, HVC were more likely to utilize endovascular repair (31.0% vs. 21.9%, p < 0.001). Rates of death, amputation, and compartment syndrome were similar. HVC were more likely to develop pneumonia or sepsis. On logistic regression, HVC was not associated with survival (OR: 0.90, 95%CI: 0.60-1.34, p = 0.60). Variables associated with mortality for HVC and LVC included thoracic arterial injury (OR: 1.57, 95%CI: 1.27-1.94, p < 0.001), penetrating mechanism (OR:1.84, 95%CI: 1.57-2.15, p < 0.001), and open repair (OR: 1.95, 95%CI: 1.69-2.26, p < 0.001). Lower ISS (OR: 0.29, 95%CI: 0.24-0.34, p < 0.001) and higher presenting blood pressure (OR: 0.99, 95%CI: 0.99-1.00, p < 0.001) were associated with survival. CONCLUSIONS: Although LVC may have less proficiency with endovascular techniques, trauma center volume does not influence survival in emergency surgery for MVI.
