Neurointerventional
radiology is a medical specialty dedicated to the treatment of vascular
disease involving the central nervous system using the latest
minimally invasive technologies. Tiny flexible catheters from within
blood vessels are used to access vessels in the brain and spinal
cord to successfully treat numerous disabling diseases without the
need for more invasive and traumatic open neurological surgery.
A second new
procedure performed at the University
Hospital was endovascular
coiling on a brain aneurysm. Brain aneuryms are an abnormal ballooning
of an artery, and account for about 20 per cent of all strokes.
Left untreated, they can cause major damage to the brain, or death.
A common treatment is surgery, in which a section of the skull is
removed so that the aneurysm can be clipped to stop the flow of
blood. This technique has high morbidity and mortality rates. However,
endovascular coiling, as a minimally invasive procedure, is an excellent
alternative to surgery since it avoids the additional stress of
recovery from major brain surgery for the patient.
Endovascular
treatment involves insertion of a catheter into the femoral artery
in the patient's leg, navigating it through the vascular system
under X-ray guidance, into the head and into the aneurysm. Tiny
platinum coils are then threaded through the catheter and into the
aneurysm, obstructing blood flow into the aneurysm and preventing
further damage.
In April 2003,
Dr. Tanveer ul Haq, Associate Professor, Department of Radiology,
successfully carried out the first one-and-a-half-hour life-saving
endovascular coiling procedure on a 57-year old female patient under
general anaesthesia. Dr. Tanveer says, "The endovascular coiling
procedure offers tremendous benefits to patients, as we can prevent
an aneurysm from rupturing."
