About Dr. Piyush Ojha

Dr. Piyush Ojha is a Clinical Director of Neurology and Head of Neurointervention at Marengo Asia Hospitals in Gurugram, bringing 17 years of specialized expertise in Interventional Neuroradiology and Stroke Neurology. He holds a distinctive dual-fellowship qualification — both in Interventional Neuroradiology from Medanta – The Medicity, Gurugram, and in Stroke Medicine from the University of Calgary's renowned Calgary Stroke Program in Canada — a credential held by very few neurologists globally. His comprehensive medical training includes MD Medicine from MGM Medical College (where he was Gold Medalist) and DM Neurology from Government Medical College, Kota.

Dr. Ojha's clinical practice focuses on minimally invasive endovascular treatment of complex neurovascular conditions, including intracranial aneurysm coiling, mechanical thrombectomy for acute ischemic stroke, embolization of arteriovenous malformations and dural arteriovenous fistulas, carotid and intracranial arterial stenting, and comprehensive acute stroke management. His integrated approach ensures that patients with life-threatening stroke and vascular brain pathologies receive time-critical, expert care under a single physician. He manages high case volumes across all major neurovascular interventions and is recognized for his technical precision and patient outcomes.

Beyond clinical practice, Dr. Ojha is a prolific researcher and educator. He has authored or co-authored over 50 peer-reviewed research publications and won the prestigious WSC Young Investigator Award at the World Stroke Congress (2022). He mentors DM residents and stroke fellows, serves as faculty at Indian Stroke Association conferences and the Stroke Summer School, and reviews manuscripts for leading neurology and neurointervention journals. His commitment to stroke awareness extends to community education initiatives across India. International patients, particularly from the Gulf region, Africa, and SAARC countries, benefit from his multilingual approach (English and Hindi) and experience managing complex cases referred from abroad.

Marengo Asia Hospitals, where Dr. Ojha leads the Neurointervention unit, is a NABH-accredited multispecialty centre in the National Capital Region with state-of-the-art neurocritical care, advanced imaging (3D angiography, CT perfusion), and dedicated stroke protocols. The hospital's integration of acute stroke services with 24/7 interventional capability makes it an ideal destination for international patients seeking urgent or elective neurovascular care. Patients from overseas appreciate the hospital's international coordination desk, clear communication in English, and streamlined pathways for pre-arrival consultation and post-procedure follow-up through Gaf Healthcare's telehealth platform.
