Concept
Interventional neuroradiology
Résumé
Interventional neuroradiology (INR) also known as neurointerventional surgery (NIS), endovascular therapy (EVT), endovascular neurosurgery, and interventional neurology is a medical subspecialty of neurosurgery, neuroradiology, intervention radiology and neurology specializing in minimally invasive image-based technologies and procedures used in diagnosis and treatment of diseases of the head, neck, and spine.
Diagnostic angiography
Cerebral angiography was developed by Portuguese neurologist Egas Moniz at the University of Lisbon, in order to identify central nervous system diseases such as tumors or arteriovenous malformations. He performed the first brain angiography in Lisbon in 1927 by injecting an iodinated contrast medium into the internal carotid artery and using the X-rays discovered 30 years earlier by Roentgen in order to visualize the cerebral vessels. In pre-CT and pre-MRI, it was the only tool to observe the structures within the skull and was also used to diagnose extravascular pathologies.
Subsequently, European radiologists further developed the angiographic technique by replacing the traumatic direct puncture with catheterization: in 1953, Swedish physician Sven Seldinger introduced the technique of arterial and venous catheterization still in practice, dubbed the Seldinger Technique. In 1964, the Norwegian radiologist Per Amudsen was the first to perform a complete brain angiography with a transfemoral approach, as it is performed today; he then moved to San Francisco to teach the technique to American neuroradiologists. These two stages, at the basis of modern invasive vascular diagnostics, prepared the way for later therapeutic developments.
The first treatments: balloon occlusion
The first to carry out a true endovascular procedure was Charles Dotter, the father of angioplasty and considered by many as the father of all interventional radiology, as well as the first doctor to have performed endovascular treatment. On January 16, 1964, he performed a therapeutic angioplasty of a superficial femoral artery in an 82-year-old woman with an ischemic leg refusing amputation.
