Clinical outcomes of radiofrequency ablation for patients with varicose veins of the lower extremities combined with grade II iliac vein compression.

BACKGROUND: Iliac vein compression (IVC) is a common condition in patients with varicose veins (VVs) of the legs. IVC has been classified into three grades in previous studies. Grade II IVC is defined by >50% stenosis without the development of collateral circulation. The purpose of the present study was to investigate the outcomes of radiofrequency ablation (RFA) for patients with VVs combined with grade II IVC. METHODS: A retrospective analysis was conducted of 339 patients who had undergone RFA for VVs of the left leg from March 2017 to January 2019. Duplex ultrasonography, computed tomography venography, and venography were performed to evaluate for grade II IVC. All the patients were divided into two groups. Group 1 included patients with VVs only, and group 2, patients with VVs combined with grade II IVC. Propensity score matching was used to ensure an even distribution of confounding factors between groups. The venous clinical severity score (VCSS) and chronic venous insufficiency questionnaire (CIVIQ) score were recorded during the 12-month follow-up. Occlusion of the truncal veins was evaluated using duplex ultrasound scans. RESULTS: Using 1:1 propensity score matching, 50 pairs of patients were enrolled in the present analysis. The average age of groups 1 and 2 was 58.7 ± 13.1 and 60.1 ± 7.1 years, respectively. The VCSS had decreased significantly from baseline to 12 months postoperatively (group 1, from 5 to 1; group 2, from 4 to 1; P < .01). A significant increase in the CIVIQ score was found between the baseline and 12-month evaluations for both groups (group 1, from 62.5 to 69; group 2, from 63 to 70; P < .01). The truncal occlusion rate was 98% in both groups at 12 months. No significant differences were found between the two groups in the VCSS, CIVIQ score, procedure complications, or occlusion rate during the 12-month follow-up. CONCLUSIONS: RFA is effective for patients with VVs combined with grade II IVC.

COVID-19 Presented With Deep Vein Thrombosis: An Unusual Presenting.

On December 31, 2019, the World Health Organization was informed of a cluster of cases of pneumonia of unknown cause detected in Wuhan City, Hubei Province, China. The pneumonia was caused by a virus called SARS-Cov-2 (severe acute respiratory syndrome coronavirus 2), which was later named coronavirus infectious disease 2019 (COVID-19). The symptoms most commonly reported by patients affected by COVID-19 include fever, dry cough, and shortness of breath. In this report, we present a case of a 57-year-old woman who presented to the clinic's infectious department with swelling, pain, warmth, and redness in the left leg who was treated with therapeutic heparin. There were no typical and distinguished symptoms of COVID-19, and she had no risk factor for deep vein thrombosis. Then chest X-ray revealed bilateral patchy ground-glass opacity, and computed tomography angiography was performed to rule out pulmonary thromboembolism, which showed no evidence of thrombosis. Left lower limb venous color Doppler ultrasound revealed dilatation and thrombosis in the external iliac and left iliac veins up to the level of the bifurcation of the common iliac veins, as well as thrombosis to the superficial and small saphenous veins. Because of ground-glass opacity and lymphopenia, nasal swabs were used for sampling, and SARS-CoV-2 nucleic acid was detected by reverse transcription polymerase chain reaction (RT-PCR). This case aims to arouse the medical staff's awareness of deep vein thrombosis as a clinical symptom of COVID-19 even if the patient has no typical symptoms of COVID-19.
