Renal arteriovenous malformations are abnormal communications between the intrarenal arterial and venous systems. They are a rare cause of hematuria. Color Doppler ultrasonography, multislice CT angiography, and DSA are important tools for making the diagnosis. We describe the case of a 62-year-old man with renal arteriovenous malformation who presented with gross hematuria.
Introduction Published evidence of venous thrombotic complications of COVID-19 is lacking from India. This case series consists of twenty-nine adult patients who were COVID -19 positive and treated for Deep Vein Thrombosis (DVT) during the second wave of the COVID-19 pandemic, in India. The study was aimed at analyzing patient demographics of patients with DVT and the outcome of Catheter-Directed Thrombolysis (CDT) in COVID positive patients. Material and Methods: Patients who developed DVT while or after being COVID positive were managed between February and April 2021 at the institution of the first two authors and were included in this retrospective study. Demographic, clinical data, laboratory data, and treatment given were analyzed. All patients were followed up for 3 months with a Villalta score. Results: There were a total of 29 patients (12 male and 17 female) included in the study with a mean age of 47 ± 17 years. The average time of presentation from being COVID positive was 17.8 ± 3.6 days and one patient developed DVT after becoming Covid negative. All but one patient had lower limb involvement, with 42.8% having proximal and 57.2% distal DVT. All patients with Iliofemoral and two with Femoropopliteal DVT were treated with catheter-di thrombolysis and the other 15 patients were managed with anticoagulation alone. No re-thrombosis was observed in the thrombolysis group. Overall average Villalta score at 3 months was 10.7 ± 2.1 with a score of 10.58 ± 2.1 in the anticoagulation-only group and 10.85 ± 2.3 in the CDT group. Conclusion: COVID-19 seems to be an additional risk factor in the development of DVT. The outcome of such patients, treated by thrombolysis appears to be similar to non-COVID patients. In this, observational experience of the authors suggests that CDT could be offered to COVID positive patients with symptomatic Iliofemoral DVT with good outcomes and an acceptable post-intervention Villalta score.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
