Nowadays, abdominal catheterizations are mainly guided by 2D fluoroscopic imaging from one view, which complicates this task due to missing depth information, vessel invisibility, and patient motion. We propose a new technique for 3D navigation of guide wires based on singleplane 2D fluoroscopic views and a previously extracted 3D model of the vasculature. In order to relate the guide wire, whi...

In this report, we propose a complete pipeline for guide-wire segmentation and tracking in the context of cardiac angioplasty. Segmentation is addressed through a bottom up approach which first detects interest points using appropriate features. These points are then clustered into local segments using geometric and proximity constraints. Ordering of these segments through a local permutation m...

Left Atrial pressure monitoring is a useful and accurate method to guide Left ventricle filling in the patients who undergo Arterial switch operation for transposition of great arteries. We have used a different technique in three TGA patients for LA pressure monitoring line placement. After cleaning and draping,right internal jugular vein (rt IJV) located through 22G venous cannula, guide wire...

An 82 years-old man with intermittent claudication was admitted to our hospital. Computed tomography angiography showed his right superficial femoral artery (SFA) was chronic total occlusion (CTO), and we performed endovascular treatment (EVT). We advanced a guide-wire by contralateral transfemoral approach, but guide-wires could not penetrate the occluded SFA lesion antegradely. Thus, we tried...
