Is Routine Preprocedural Bloodwork Needed for Elective Central Venous Access Device Removals in Children without Bleeding Dyscrasias?

PURPOSE: To assess the utility of routine preprocedural bloodwork during elective removal of central venous access devices (CVADs) with respect to bleeding complications. MATERIALS AND METHODS: Patients who underwent removal of a CVAD (tunneled central venous catheter [CVC] or port) by the interventional radiology service between January 2009 and December 2013 were retrospectively reviewed. Removals for infection or malfunction, without preprocedural bloodwork, with another concurrent procedure at the time of CVAD removal, or in patients with a bleeding dyscrasia were excluded. Peripherally inserted central catheter removals and temporary CVAD removals were also excluded. Routine preprocedural bloodwork included hemoglobin, platelet count, partial thromboplastin time, and International Normalized Ratio. Postprocedural complications were classified according to the Society of Interventional Radiology clinical practice guidelines. RESULTS: There were 802 CVAD removals in 777 patients (351 female, 426 male). Average patient age was 8.6 years (range, 5 wk to 19 y). In total, 246 permanent CVCs and 556 ports were removed. A total of 802 cases had preprocedural bloodwork. Of the 49 patients who had a bleeding complication after the procedure (6.1%; 49 of 802), 44 had normal findings on preprocedural bloodwork and 5 had abnormal findings. There was no statistically significant difference in bleeding complications between those with normal and abnormal bloodwork results (P = .7740). CONCLUSIONS: Routine bloodwork is not necessary before elective CVAD removal in children without a bleeding dyscrasia. Most children have normal findings on preprocedural bloodwork, and the incidence of postprocedural bleeding is low and not determined by bloodwork results.
