The patient was a 60-year-old man with encephalopathy without liver cirrhosis. CT angiography revealed a patent ductus venosus between the anterior segmental branch of the portal vein and the middle hepatic vein. Coils were framed in the patent ductus venosus and then used to fill in the frame. After treatment, ...

The identification of infundibula on noninvasive imaging modalities may be challenging. Because these lesions have generally been viewed as nonpathological, distinguishing them from small or micro-aneurysms is important. A 39-year-old male was diagnosed with recurrence of typical orgasmic headache. An outpoutching arising from the distal part of the right P1 ...

The substrate of paradoxic embolization is a patent foramen ovale allowing right-to-left passage of embolic material. A thrombus in transit entrapped by a patent foramen straddling an atrial septal aneurysm is an exceedingly transient condition rarely documented on imaging studies. We present the case of a 67-year-old man with acute ...

Retrograde or combined retrograde and antegrade recanalization should be considered when antegrade recanalization has failed in selected patients with critical limb ischemia (CLI). Retrograde recanalization is typically attempted through a patent segment of the popliteal artery or an infrapopliteal artery. The challenge arises, however, when there are no patent popliteal ...

We investigated tissue responses to endoskeleton stent grafts for saccular abdominal aortic aneurysms (AAAs) in canines. Saccular AAAs were made with Dacron patch in 8 dogs, and were excluded by endoskeleton stent grafts composed of nitinol stent and expanded polytetrafluoroethylene graft. Animals were sacrificed at 2 months (Group 1; n ...

This report discusses a premature complex newborn with persistent pulmonary difficulties following the clipping of the PDA. Bronchoscopy was critical in revealing a metallic clip obstructing the bronchus. Thoracothomy revealed that the clip had been placed across the bronchus. This case illustrates the importance of bronchoscopy in the face of ...

Arteriovenous malformations arising from iliac arteries are rare anomalies. Percutaneous embolization of such malformations is an established therapeutic option. In this paper, we will describe a case, wherein the internal iliac artery feeding a giant arteriovenous fistula was closed using a patent ductus arteriosus (PDA) duct occluder percutaneously. The PDA ...

The indication for pulmonary metastasectomy has been postulated based on nonrandomized clinical experiences. The postoperative survival rate of selected patients with pulmonary metastasis is acceptable; nevertheless, pulmonary metastasectomy might cure patients if the neoplastic cells are located only in the lung parenchyma. Computed tomography has been the most reliable preoperative ...
