I was scared too.
I spoke to various ppl of many branches. No one liked it either.
I spoke to mu Guru, Dr. Sunil Pandya, of Hydrabad, Jr. to me by many yrs, but still I call him Guru.
His opinion was that, it is not CSF leak. He has seen a few cases where he was called upon.
It is edema fluid leak, especially, these malignancy and hypoprotenaemic patients. He said you may see it as a leaking tap at times. Even from the IV sites.
After this I saw the paitent again in a different light. There was no more leak. Patient was discharged home on fifth day of surgery, now going for further chemo management.
Thanks for your kind support.
