Abstract: fewer complications.Detection of thrombosis associated with CVC is also becoming easier with the use of ultrasonographic (USG) (duplex).Early detection of thrombosis associated with CVC helps to prevent DVT.Assessing the risk factors for the incidence of thrombosis with CVC is crucial for preventing thrombosis and reducing the associated morbidity and mortality.This study aimed to identify the prevalence of thrombosis with IntroductIonIn the intensive care unit (ICU), central venous catheterization (CVC) is a frequently performed procedure for various indications.A significant number of ICU patients require the placement of a catheter into a central vein for administering fluids and/or monitoring.Despite its necessity, this procedure is not without risks.Potential complications associated with CVC include catheterrelated thrombosis (CRT), pulmonary embolism, bloodstream infections linked to the catheter, catheter malfunction, and postthrombotic syndrome.1,2 The process of inserting a catheter is suspected to damage the vascular endothelium and promote the formation of a thrombus, which can eventually grow and obstruct the vein lumen. 2 Ultrasound duplex Doppler is the most appropriate imaging modality to assess upper-extremity deep vein thrombosis (DVT).3 Further testing, such as D-dimer or venography, is only required if clinical suspicion remains high after a negative result.The management protocol consists of the initial administration of low-molecular-weight heparin (LMWH), subsequently transitioning to vitamin K antagonists for a period of at least 3 months.4 Lower-limb DVT and pulmonary embolism are the two main entities prevalent in ICUs for various reasons.Upper-extremity DVT is uncommon, but in recent days, the incidence has been increasing due to the more frequent use of CVC.5,6 Previously, we placed CVCs using landmark techniques, but now, with the help of ultrasonography, placing the CVC has become easier with
