OBJECTIVE: COVID-19 infection results in a hypercoagulable state predisposing patients to thrombotic events. We report the 3- and 6-month follow-up of 27 patients who experienced acute arterial thrombotic events in the setting of COVID-19 infection. METHODS: Data were prospectively collected and maintained for all vascular surgery consultations in the Mount Sinai Health System from patients who presented between March 16 and May 5, 2020. RESULTS: Twenty-seven patients experienced arterial thrombotic events. The average length of stay was 13.3 ± 15.4 days. Fourteen patients were treated with open surgical intervention, six were treated with endovascular intervention, and seven were treated with anticoagulation only. At 3-month follow-up, 11 patients (40.7%) were deceased. Nine patients who expired did so during the initial hospital stay. The 3-month cumulative primary patency rate for all interventions was 72.2%, and the 3-month primary patency rates for open surgical and endovascular interventions were 66.7 and 83.3, respectively. There were 9 (33.3%) readmissions within 3 months. Six-month follow-up was available in 25 (92.6%) patients. At 6-month follow-up, 12 (48.0%) patients were deceased, and the cumulative primary patency rate was 61.9%. The 6-month primary patency rates of open surgical and endovascular interventions were 66.7% and 55.6%, respectively. The limb-salvage rate at both 3 and 6 months was 89.2%. CONCLUSIONS: Patients with COVID-19 infections who experienced thrombotic events saw high complication and mortality rates with relatively low patency rates.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a novel coronavirus that has typically resulted in upper respiratory symptoms. However, we have encountered acute arterial and venous thrombotic events after COVID-19 infection. Managing acute thrombotic events from the novel virus has presented unprecedented challenges during the COVID-19 pandemic. In our study, we have highlighted the unique treatment required for these patients and discussed the role of anticoagulation for patients diagnosed with COVID-19. METHODS: The data from 21 patients with laboratory-confirmed COVID-19 disease and acute venous or arterial thrombosis were collected. The demographics, comorbidities, home medications, laboratory markers, and outcomes were analyzed. The primary postoperative outcome of interest was mortality, and the secondary outcomes were primary patency and morbidity. To assess for significance, a univariate analysis was performed using the Pearson χ2 and Fisher exact tests for categorical variables and the Student t test for continuous variables. RESULTS: A total of 21 patients with acute thrombotic events met our inclusion and exclusion criteria. Most cases were acute arterial events (76.2%), with the remainder venous cases (23.8%). The average age for all patients was 64.6 years, and 52.4% were male. The most prevalent comorbidity in the group was hypertension (81.0%). Several markers were markedly abnormal in both arterial and venous cases, including an elevated neutrophil/lymphocyte ratio (8.8) and D-dimer level (4.9 µg/mL). Operative intervention included percutaneous angiography in 25.00% of patients and open surgical embolectomy in 23.8%. Most of the patients who had undergone arterial intervention had developed a postoperative complication (53.9%) compared with a 0% complication rate after venous interventions. Acute kidney injury on admission was a factor in 75.0% of those who died vs 18.2% in the survivors (P = .04). CONCLUSIONS: We have described our experience in the epicenter of the pandemic of 21 patients who had experienced major thrombotic events from infection with COVID-19. The findings from our cohort have highlighted the need for increased awareness of the vascular manifestations of COVID-19 and the important role of anticoagulation for these patients. More data are urgently needed to optimize treatment and prevent further vascular complications of COVID-19 infections.

We describe three patients with COVID-19 who presented with an acute vascular event rather than with typical respiratory symptoms. These patients were all subsequently found to have laboratory-confirmed COVID-19 infections as the likely cause of their thrombotic event. The primary presentation of COVID-19 infection as a thrombotic event rather than with respiratory symptoms has not been described elsewhere. Our cases and discussion highlight the thrombotic complications caused by COVID-19; we discuss management of these patients and explore the role of anticoagulation in patients diagnosed with COVID-19.
