SYNPOSIS
The episode begins with the most vital component of patient care: establishing a correct diagnosis through proper classification. Dr. Weiss shares his philosophy that “MRI is a conversation” - not just an image, detailing the specific MRI protocols to confidently make a diagnosis over 90% of the time. He then shares an overview of the classification system, differentiating vascular tumors like hemangiomas from high-flow and low-flow vascular malformations.
Dr. Weiss explores a wide array of treatment strategies tailored to each diagnosis. He walks through his techniques for treating low-flow malformations with sclerotherapy—using agents like alcohol, doxycycline, and bleomycin based on a lesion’s location and characteristics—and his use of cryoablation for vascular tumors. He then dives into the creative and high-stakes approaches for treating AVMs, comparing transvenous and transarterial embolization with agents like Onyx and coils, before concluding with his predictions on the future of IR in the field.
