Pre-Procedure Thrombocytopenia and Leukopenia Association with Risk for Infection in Image-Guided Tunneled Central Venous Catheter Placement.

Placement of image-guided tunneled and non-tunneled large-bore central venous catheters (CVCs) are common procedures in interventional radiology. Although leukopenia and/or thrombocytopenia are common at the time of placement, the roles these factors may have in subsequent catheter-related infection have yet to be investigated. A single-institution retrospective review was performed in patients who underwent CVC placement in interventional radiology between 11/2018-6/2019. The electronic medical record was used to obtain demographics, procedure details, pre-placement laboratory values, and the subsequent 90-day follow-up. A total of 178 tunneled and non-tunneled CVCs met inclusion criteria during this time period. White blood cell (WBC) and platelet counts were found to be significant risk factors for subsequent infection. Administration of pre-procedure antibiotics was not found to be a significant factor for subsequent infection ( p = 0.075). Leukopenia and thrombocytopenia at the time of CVC placement are both risk factors of line infection for tunneled large-bore CVCs. This should lead to the consideration of using a non-tunneled CVC when clinically feasible, or the delayed placement of these catheters until counts recover.
