3D rotational angiography (3DRA) and CT-fluoro image fusion can enhance fluoroscopy by optimizing C-arm angles and allowing real-time overlay of 3D regions of interest on 2D fluoroscopy. This case series demonstrates the techniques and utility of 3DRA and CT-fluoro image fusion during transcatheter stenting of aortic coarctations.
Coarctation stenting was performed using either conventional 2D fluoroscopy, 3DRA or 2D3D image fusion. We noted fluoroscopy time, radiation exposure and number of angiograms.
|Meadian Fluoroscopy time in mins (range)||Median number of planning angiograms (range)||Median 3DRA Skin Dose in mGy (range)||Median Total DAP (range)||Median Total Skin Dose in mGy (range)|
|2D Fluoroscopy (n=3)||32.2 (15.4-39.5)||5 (5-6)||NA||27759.5 (8226.9-51921)||2098.94 (819.7-4429)|
|3DRA (n=3)||26.23 (18.8-29.7)||3 (3-4)||108 (79.47-159.2)||32429 (10079-38240)||1946 (695-2445)|
3DRA and image fusion offer additional guidance by helping optimization of C-arm angles and providing a roadmap for the intervention. We believe that such multi-modality imaging may improve safety and efficiency of this procedure. This needs further validation.
