Retrospective study @BLK Total patients: 126 VAD 14 44 Hickman catheter Male 112 Female Chemoport 82
Indications Benign hematological disorder Duration of study :37 months Mean duration of catheter in situ: 116.13 days Median catheter days:180 days Minimum age:5months Maximum age:18 yrs 15 Hematological malignancies 31 80 Solid tumors
Procedure Right internal jugular vein 101 patients had double lumen catheter 11 patients had single lumen catheter
Overall complications: 13/126 Intraoperative 2 Hematoma formation 1 Supraventricular Tachycardia 1 Premature removal 11 Accidental removal 1 Transmigration of catheter into right pulmonary artery 1 Catheter misplacement 2 Catheter blockage 1 Fracture of catheter 2 Infection 4
Conclusion Complication rates are less than/comparable to the studies reported in literature showing rates of premature removal between 10% to 30.2% (Our study:10.3%). Catheter related infections were common cause of premature removal in our study, which occurred in 3.17 % USG & flouroscopic guidance reduces: -Primary catheter malposition -Successful insertion at the first attempt -Optimum catheter tip position -Reduces mechanical occlusion Complications like pneumothorax, accidental arterial perforation ,vascular erosion, catheter compression are markedly reduced due to USG guidance -0%(our study)
