Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.
SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1-6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1-2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2-3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9-3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality ). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.
Midterm experience with placement of IBDs is associated with a low incidence of secondary procedures due to type I endoleaks and occlusions. The main reasons for reinterventions seem to be short proximal sealing zone and poor conformability of the ZBIS device in elongated EIAs.
Background: Spreading of the COVID-19 pandemic in Italy forced health facilities to drastically change their organization to face the overwhelming number of infected patients needing hospitalization. The aim of this paper is to share with all the vascular community the protocol developed by the USL (Unità Sanitaria Locale) Toscana Centro for the reorganization of the Vascular Surgery Unit during the COVID-19 emergency, hoping to help other institutions to face the emergency during the hard weeks coming. Methods:The USL Toscana Centro is a public Italian health care institution including four districts (Empoli, Florence, Pistoia, Prato) with 13 different hospitals, serving more than 1,500,000 people in a 5000 km2 area. The USL adopted a protocol of reorganization of the Vascular Surgery Unit during the first difficult weeks of the epidemic, consisting in the creation of a Vascular Hub for urgent cases, with a profound reorganization of activities, wards, surgical operators, operating blocks, and intensive care unit (ICU) beds.Results: All 13 hospitals are now COVID-19 as the first days of April passed. The San Giovanni di Dio Hospital (Florence) has more than 80 COVID-19 patients in different settings (ICU, medical and surgical ward), which at the time of writing is almost one-third of the total hospital capacity (80/260 beds). It has been identified as the Surgical Hub for urgent vascular COVID-19 cases. Therefore, the elective surgical and office activities were reduced by 30% and 80%, respectively, and reserved to priority cases. A corner of the whole operating block, well separate from the remaining operating rooms, was rapidly converted into one operating room and six ICU beds dedicated to COVID patients. The COVID-19 surgical path now includes an emergency room for suspected COVID-19 patients directly connected to an elevator for the transfer of COVID patients in the COVID operating block and dedicated COVID-19 ward and ICU beds.Conclusions: Rapid modification of hospital settings, a certain "flexibility" of the medical personnel, a stepwise shutdown of vascular surgical and office activity, and the necessity of a strong leadership are mandatory to cope with the tsunami of the COVID-19 outbreak.
Single IBD placement for isolated common iliac artery aneurysms seems to be a safe and effective treatment option, when a proper anatomic patient selection is provided. Major benefits are represented by the decrease in X ray exposure, overall procedural time, and use of contrast medium, without affecting perioperative and long-term results in comparison with more extensive procedures.
