Usefulness of preoperative color Doppler study in chronic renal failure patients undergoing renal transplantation having internal jugular vein thrombosis : anesthesiologist’s perspective

الملخص EN

Aim The aim of the study was to identify the prevalence of internal jugular vein ( IJV) thrombosis and usefulness of preoperative color Doppler study in chronic renal failure patients undergoing live related renal transplant surgery.

Materials and methods Two hundred and fi fty adult patients of either sex having history of prolonged IJV cannulation were enrolled in this study.

They were advised to undergo Doppler neck vessels study.

Normal IJV was used to measure central venous pressure during renal transplantation surgery.

Results Results are shown as mean±SD.

Two hundred and fi fty adult patients were included in the study, aged 36 ± 12 years.

All patients were cannulated with Mahorkar 16 Fr double-lumen catheter.

Duration of catheterization was 52.38 ± 18.91 days.

Of the 250 patients, 50 were female patients.

The cause of removal was infection, blockage, or maturation of arteriovenous fi stula.

All patients were clinically asymptomatic.

Color Doppler study showed chronic thrombosis either complete/partial in 93 (37.2%) patients.

Five (2%) patients had bilateral thrombosis, 80 (86%) patients had partial thrombosis, and 13 (14%) patients had complete thrombosis.

The incidence and prevalence were 0.62 and 37.2%, respectively.

Right IJV was the common site for insertion [right: 70 (75.2%) and left: 23 (24.7%)].

Conclusion To prevent inadvertent catheter placement and embolism, all patients having history of prolonged IJV cannulation should undergo preoperative color Doppler study.
