Evaluation and Coil Embolization of the Aortic Side Branches for Prevention of Type II Endoleak after Endovascular Repair of Abdominal Aortic Aneurysm

Figures

• 

  Fig. 1 Fusion (right panel) and selective angiogram (left panel). Just before the procedure, preoperative computed tomography (CT) data was imported into Singo X-Workplace of Artic Zeego and volume rendering figure was constructed. Also 3D-CT data was obtained from Artuc Zeego (Syngo DinaCT). Then, preoperative CT data was matched with Syngo DinaCT. Consequently volume rendering figure could be visualized on fluoroscopy (Fusion image). Adequate direction of fluoroscopy to identify the origin of aortic side branch was adjusted by fusion image (right panel). Then aortic side branch was selected by angiogram (left panel).

  Fig. 2 Selective angiogram with microcatheter (left panel) and coil embolization (right panel). Microcatheter was advanced into the aortic side branch and selection of target branch was comfirmed by angiogram (left panel). Then target branch was coil embolized with Interlock as close as its origin (right panel).

  Fig. 3 Diameter of IMA with or without type II endoleak. The diameter of IMA with Type II endoleak was significantly larger than those without Type II endoleak. IMA: inferior mesenteric artery

• 

  Fig. 4 Diameter of LA with or without type II endoleak. The diameter of LA with Type II endoleak was significantly larger than those without Type II endoleak. LA: lumbar artery

• 

  Fig. 5 Endoleak area of IMA and LA. Endoleak area did not differ between the two groups. However, the frequency of the patients with endoleak area 50 mm2 was significantly higher in patients with endoleak from inferior mesenteric artery. IMA: inferior mesenteric artery; LA: lumbar artery
