| Summary: | Objective: To know the value of preoperative Dopplerultrasonography vascular mapping of upper limb for hemodialysis
access placement.
Materials and Methods: Prospective ultrasonographic assessment of upper extremity vessels was performed in 60 patients
prior to hemodialysis access placement and potential access
sites were selected (based on the standard criteria). The findings
were correlated with the operative findings. Discrepancies
found between ultrasonographic and operative findings were
analysed.
Results: All the 60 patients who underwent vascular mapping had
vascular access placed. 80% of them had native arteriovenous
fistulae (AVF) placed. In 95% of patients, at the selected sites,
the vascular parameters as determined by ultrasonography
matched with the operative findings. In 5% of patients there
were discrepancies between the ultrasonography findings and
operative findings. There was no negative surgical exploration.
There was strong correlation between the diameters measured
by ultrasonography and surgery.
Conclusion: Preoperative ultrasonography vascular mapping
prior to hemodialysis access placement has facilitated definite
selection of potential sites in difficult patient population in
whom evaluation by physical examination was inconclusive. It
also helped in maximizing the native AVFs and decreasing the
negative surgical exploration rates. |
