“…There was A three-dimensional model can be constructed from helical CT scan images of a thoracic aortic aneurysm to assist in stent-graft design and in successful endoluminal positioning. In one study, 13 109 stentgrafts in 101 patients were designed by this method and were deployed well in all patients. The design time also has been reduced from 4 to 0.5 h with experience.…”

SUMMARYIn performing interventions including stent grafting, the suitability for stent grafting must be checked and the devices to be used must be designed preoperatively. For these purposes, the three-dimensional shapes of the blood vessels in lesions or the paths of device placement must be measured accurately and quickly. In this paper, a method for measuring the aortal shape from CT angiogram (CTA) and for detecting lesions from the shape characteristics of these is presented. Specifically, this method extracts the blood flow area of the aorta by using a three-dimensional edge-preserving smoothing filter and a region growing method. Extracted blood vessels are classified by using their anatomical characteristics. After initial setting of the medial axis in a blood vessel, it determines the aneurysmal area based on the diameter of the blood vessel and modifies the medial axis. In addition, it detects lesions such as thrombi and calcifications near the blood flow borderline. Application of the method to 30 clinical cases has confirmed that the proposed method is effective in obtaining the shape of blood vessels.

Aneurysm of the ductus diverticulum rarely has been reported in adults, and the reported aneurysms were treated with conventional open surgery or were diagnosed at autopsy. We report a successful endovascular repair of an aneurysm of the ductus diverticulum with the Inoue branched stent graft. In a 78-year-old woman, an abnormal shadow was noted at the aortopulmonary window on a chest x-ray film. A computed tomography scan demonstrated a 3.8-cm saccular aneurysm, which protruded inferiorly from the distal end of the aortic arch. The aneurysm was considered an aneurysm of the ductus diverticulum, and surgery was required. However, the patient was considered at high risk for respiratory dysfunction with conventional open surgery. Endovascular repair with an Inoue single-branched stent graft was performed with the patient under local anesthesia, successfully and without complication or endoleak. To our knowledge, this is the first report of endovascular treatment of an aneurysm of the ductus diverticulum.
