Venous Thrombosis After Removal of Central Venous Catheter

Rate of DVT after removal of central venous catheter

Insertion of intravenous catheter is a very common operation in patients in the general
 intensive care unit. These catheters are used for a variety of purposes - administration of
 inotropics/pressors, intravenous nutrition, concentrated electrolytes and performing
 dialysis.There are several known complications of central venous catheter insertion, such as
 thrombosis and pulmonary embolism. In a literature review, there are no clear data regarding
 the rate of intravenous thrombosis in patients after removal of a central venous catheter.
 These findings are often discovered randomly, when the patient undergoes imaging for a
 different indication. There is no recommendation for an active search for intravenous thrombi
 at the catheter insertion sites in these patients, and it is not entirely clear whether it is
 mandatory to administer anticoagulant treatment in these patients if thrombi are randomly
 discovered at the catheter insertion sites.
 
 In this study, we aim to check the proportion of patients who developed thrombosis at the
 central catheter insertion sites after its removal, to check whether there are catheter
 insertion sites that are at a higher risk of developing thrombosis than other sites, and to
 check whether there are predictive characteristics for the development of this type of
 thrombosis.
