Irene Bargellini (Pisa, Italy) tells BLearning IR that non-target embolization is a frequently under-diagnosed, sometimes fatal, problem that interventional radiologists encounter every time they work with embolics.
Understanding the vascular anatomy, identifying the non-target vessels, positioning the catheter properly, choosing the right embolic, and checking injection under fluoroscopy are all part of reducing the risk of non-target embolization, Bargellini says.
She also draws attention to new devices, such as an innovative novel microcatheter with side-holes that received CE mark in April. This device is designed to reduce the risk of embolic material reflux and works on the principle that fluids, but not embolic material, exit from the side-holes and create a vortex that acts as a barrier to prevent reflux.
