RESUMO
OBJECTIVE: The COVID-19 pandemic has drastically altered the medical landscape. Various strategies have been employed to preserve hospital beds, personal protective equipment, and other resources to accommodate the surges of COVID-19 positive patients, hospital overcapacities, and staffing shortages. This has had a dramatic effect on vascular surgical practice. The objective of this study is to analyze the impact of the COVID-19 pandemic on surgical delays and adverse outcomes for patients with chronic venous disease scheduled to undergo elective operations. METHODS: The Vascular Surgery COVID-19 Collaborative (VASCC) was founded in March 2020 to evaluate the outcomes of patients with vascular disease whose operations were delayed. Modules were developed by vascular surgeon working groups and tested before implementation. A data analysis of outcomes of patients with chronic venous disease whose surgeries were postponed during the COVID-19 pandemic from March 2020 through February 2021 was performed for this study. RESULTS: A total of 150 patients from 12 institutions in the United States were included in the study. Indications for venous intervention were: 85.3% varicose veins, 10.7% varicose veins with venous ulceration, and 4.0% lipodermatosclerosis. One hundred two surgeries had successfully been completed at the time of data entry. The average length of the delay was 91 days, with a median of 78 days. Delays for venous ulceration procedures ranged from 38 to 208 days. No patients required an emergent intervention due to their venous disease, and no patients experienced major adverse events following their delayed surgeries. CONCLUSIONS: Interventions may be safely delayed for patients with venous disease requiring elective surgical intervention during the COVID-19 pandemic. This finding supports the American College of Surgeons' recommendations for the management of elective vascular surgical procedures. Office-based labs may be safe locations for continued treatment when resources are limited. Although the interventions can be safely postponed, the negative impact on quality of life warrants further investigation.
RESUMO
OBJECTIVE: It is unclear if the addition of a prophylactic arch operation is beneficial at the time of root replacement in patients with Marfan syndrome (MFS). This project aims to understand the fate of the distal aorta following elective root replacement in patients with MFS. METHODS: Between 2000 and 2019, 124 adult patients with MFS were identified as having undergone elective aortic root replacement with a clamped distal aortic anastomosis during their lifetime. Serial axial imaging was analyzed. The primary outcome was a composite of subsequent type B aortic dissection (TBAD), aneurysmal degeneration (>4 cm), and aortic reintervention. Secondary outcomes included subsequent TBAD and mortality. RESULTS: Mean age at root replacement was 33.3 years. Median follow-up was 11.3 years. Thirty-one patients (25%) experienced the primary outcome, with no survival difference (P = .9). The crossclamp and aortic cannulation sites were stable (growth rate, 0.33 mm/year), and 2 patients (1.6%) required reintervention there. Twenty-three patients (19.8%) experienced subsequent TBAD. Patients with TBAD had a higher rate of distal degeneration (P < .001), but no significant change in survival (P = .2). Preoperative hypertension (odds ratio, 3.96; P < .05) and younger age at root replacement (odds ratio, 1.05; P < .05) increased the risk of TBAD, based on regression analysis. CONCLUSIONS: The distal aorta (including the clamp and cannulation site) overall appears stable in patients with MFS following elective root replacement without prophylactic arch operation. Development of TBAD seems to be the primary driver of distal degeneration. Factors associated with TBAD development included hypertension, underscoring the importance of strict blood pressure control in these patients.
