Aneurysm stent graft extending into common Illiac
If you embolize the internal iliac artery, what complication can result?

All peripheral arteries with aneurysms require 2 AVP devices (front and back door blocking ) to isolate the disease region
False
What is the key goal of treating PAVM with embolisation
Increase blood saturation
Prevent stroke
Prevent brain abscess
Which of the following artery is necessary to embolize before pt proceed to SIRT
Gastroduodenal artery
What are the 3 mechanisms of actions of the AVP
Activate natural coagulation process
Create a physical barrier to blood flow
Instigate the body,s immune response
Which AVP delivery system is compatible with selected diagnostic catheters?
