Interventional Radiological treatment

Interventional radiology is my favorite specialty.
My dad had an intestinal bleed. The doctors all warned me of dire consequences of surgery, when suddenly the IR doctor arrived, shouting "what are you trying to kill this guy. Get him to the surgical suite, now! He turned to wink at me and said, "We'll be back, 20 minutes." Shorter procedure time, avoiding open surgery with all it's wounds and muscle displacement faster healing, fewer complications.
Best wishes for your sister's recovery.

IR procedures are much less invasive than surgery. I have an interventional radiologist for my neuroendocrine lung cancer. He destroyed the largest tumor with microwave ablation using probes through my back, no surgery. So much better than having a lung lobe surgically removed. He's one of my favorite specialists! And how often do you actually get to talk to a radiologist about your scans? They understand what they are looking at and can answer all your questions regarding the scan. Most doctors are just reading the scan report with me and can't answer any questions past what I just read. Prayers for your sister.

Thank you for your reply and experience. When you say probes thru back, do you mean electronic probes? not physical probes thru tissue? Your post has me feeling more confident about this interesting procedure. Thank you again

They were physical probes thru the back, thru the lung and into the tumor as it heated up the tumor to destroy it. That’s the interventional part. Not sure what the brain procedure would be for your sister but an IR is highly trained and skilled. They use imaging to guide the procedure. I was lying on a CT table during the procedure and went in and out of the CT machine many times to be sure the probes were properly placed in the tumor before heating whereas a surgeon either has a direct visual with an open incision or via camera inserted thru a small incision so IR is less invasive, faster healing.

Google “interventional radiology for brain bleeds” and you’ll receive a nice AI overview of what an IR does.
