My husband had his Grade IV AVM removed by Dr. Sekhar on August 6th, 2011. Sekhar is based out of Harborview and I can't recommend him or the hospital enough. The Neuro ICU nurses are miracle workers. They have 3 neuro ICU and 3 Neuro Acute Care wings.
I clearly don't know my dates. It was August 6th, 2012. He is still without right frontal bone until next month. Dr. Sekhar did a fantastic job. His surgery took 16.5 hrs and he faced a few complications, all of which he recovered from. (He lost 24 units of blood and had a mini-stroke).
Understandable, Ngoc K - you've both been through A LOT!!! Very best wishes on your husbands recovery & to you as well. :)
