Ayub Khan Ommaya MD, ScD (hc), FRCS, FACS (1930 - 2008) was a Pakistani American neurosurgeon and the inventor of the Ommaya reservoir.
The reservoir is used to provide chemotherapy directly to the tumor site for brain tumors.Ommaya was also a leading expert in traumatic brain injuries.
Ommaya published over 150 articles, chapters, and books.His research focused on cancer treatment, traumatic brain injury, a CSF artificial organ, and philosophy of mind.
Through discussions with Congressman William Lehman Chair of the House Appropriations Committee responsible for the Department of Transportation, he developed CDC's National Center for Injury Prevention and Control, which as part of its mission focuses on traumatic brain injury.
As part of this effort Ommaya commissioned the IOM report Injury in America.The report called for the creation of the CDC center.
Ommaya's research provided the experimental data needed to model traumatic brain injury.His Centripetal theory was foundational to the biomechanics of traumatic brain injury.
This work allowed for improved modeling of brain injury by engineers in their design of safety equipment in automobiles.Ommaya also did early work with the computed tomography (CT) scanner.
His work with Sir Godfrey Hounsfield to determine the spatial resolution of the CT scanner opened the door for its use in stereotactic surgery.
Spinal angiography was also pioneered by Ommaya, Di Chiro, and Doppman.This work allowed for the visualization of arteries and veins and allowed for understanding of spinal cord arteriography.
The same team reported the treatment of spinal cord AVMs by percutaneous embolization of an intercostal artery using stainless steel pellets.
This was one of the first reports of interventional neuroradiology.Ommaya made several significant contributions to many areas that concern neurological surgeons, treatment of cancer, hydrocephalus, traumatic brain injury, and arterio-venous malformations.
