| 内容記述 | Miss-placement of arteries while using the roadmap technique in endovascular interventions for abdominal arteries occurs because of respiration. It has been reported that abdominal arteries move mainly in a superior-inferior direction and that diaphragm position helps to compensate for the miss-placement. We investigated the reliability of a roadmap technique with respiratory motion compensation that used diaphragm positions to cancel out any miss-placement of the hepatic arteries. From three patients, we obtained five pairs of fluoroscopic sequences and digital subtraction angiography (DSA) images. The coordinates of the right hemi-diaphragm and a micro guide-wire tip were noted for every frame of the fluoroscopic sequence along with the coordinates of the right hemi-diaphragm on the DSA image. The micro guide-wire tip coordinates were corrected using the difference of the Y coordinate values from both hemi-diaphragms. The tip positions that were successfully placed on arteries in the DSA image were counted and the success rate calculated. Mean success rates for two cases were over 90%, though that for the other was under 10%. The results indicate that reliability of the roadmap technique with respiratory motion compensation depends on the particular case. However, this method could stabilize the micro guide-wire tip position. | |||||
