Abstract
Background: Catheter-related thrombosis (CRT) is a significant complication in patients requiring long-term intravenous access. This study explores the clinical profile, incidence, and associated patient- and device-related risk factors for CRT. Understanding these risk factors can help develop preventive strategies and reduce thrombotic complications.
Objective: To analyze the clinical profile, incidence, and patient- and device-related risk factors for catheter-related thrombosis in hospitalized patients.
Material and Methods: A total of 60 patients requiring intravenous catheterization were enrolled from the Department of Medicine at a tertiary care hospital. Patient characteristics, catheter type, site of insertion, and duration were recorded. Incidence of thrombosis was assessed using clinical and Doppler studies.
Results: Out of the 60 patients, 15 (25%) developed catheter-related thrombosis. Risk factors such as the use of central venous catheters, prolonged catheter duration, and associated co-morbidities significantly increased the risk. The mean duration of catheter use was 10.4 ± 2.3 days in patients with thrombosis. A higher incidence of thrombosis was found in patients with malignancy and hypercoagulable states.
Conclusion: Catheter-related thrombosis is influenced by patient- and device-specific factors, with central venous catheters, prolonged duration, and underlying comorbidities playing a crucial role. Identifying and addressing these risk factors can minimize the occurrence of CRT and improve patient outcomes.
