Adult and Pediatric Interventional Radiology
Patients and their physicians turn to me to assist in the care of complex medical problems using the safe, minimally-invasive and innovative technologies the field of interventional radiology is built upon. I strive to provide individualized care to each of my patients based on the latest scientific evidence, practice experience from training at some of the nations' top institutions, and above all, their specific needs.
As an image-guided specialist, my patients are offered targeted, minimally-invasive, therapeutic options for diseases that have historically been untreatable or required extensive and morbid surgical operations.
Rex Pillai, M.D., associate clinical professor, is a minimally-invasive vascular and image-guided specialist performing diagnostic and interventional procedures for adult and pediatric patients. He has expertise in tumour-directed arterial therapy (chemo and radioembolization), tumor ablation and other cutting-edge therapies focusing on liver, kidney, lung, soft tissue and bone cancers.
He treats female patients with symptomatic fibroids (uterine fibroid embolization) and pelvic congestion syndrome as well as male patients with varicoceles.
His specialized clinical interests also include the treatment of vascular and lymphatic malformations, acute and chronic deep venous thromboembolic disease (DVT), complex IVC filter retrievals, portal hypertension as well as pediatric percutaneous and endovascular image-guided interventions.
Dr. Pillai's research interests include applying endoscopic tools to treat biliary disease, novel treatments for vascular malformations, evaluating treatment methodologies and responses of hepatic tumours to radioembolization and biomedical device development.
