Superselective angiographic embolization for intractable epistaxis.

Conclusions: Routine embolization of the ipsilateral facial artery (FA) is effective because of the high success rate. The use of different embolic materials for the internal maxillary artery (IMA) and the FA was considered safe because of the absence of major complications.

Objective: To evaluate outcomes of routine embolization of the FA as well as the IMA ipsilateral to the bleeding site for intractable epistaxis, and outcomes using different embolic materials for the FA and the IMA.

Transradial approach for noncoronary angiography and interventions.

Purpose: The purpose of this study was to retrospectively evaluate the feasibility and safety of a transradial approach for non-coronary angiography and interventions.

Background: Generally, the transradial approach is used for coronary angiography and intervention around the world, and experiences have been widely reported. However, few large studies have examined the transradial approach for vessels other than the coronary or cerebral artery.

Iatrogenic venous air embolism caused by CT injector--from a risk management point of view.

An iatrogenic venous air embolism caused by computed tomography (CT) injector occurred in a 74-year-old man undergoing abdominal-pelvic CT for evaluation of an abdominal aortic aneurysm (AAA). During the initial inspection scan of the thoracic part, a large amount of air was detected in the right ventricle, but no contrast medium was noted in the aorta. Surface oxygen was given immediately, and the patient was placed in the left lateral decubitus position on the CT bed.

T2-weighted MR imaging of prostate cancer: multishot echo-planar imaging vs fast spin-echo imaging.

The aim of the present study was to assess the performance of pre-biopsy T2-weighted MR imaging using multishot echo-planar imaging (EPI) sequence for visualization of prostate cancer and to compare image quality with that of fast spin-echo (FSE) sequence. Thirty-nine patients with suspected prostate cancer and one healthy male volunteer were examined on a 1.5-T MR scanner equipped with a pelvic phased-array coil.

[A case of thymic carcinoma responded to intra-arterial chemotherapy combined with radiation therapy].

A 70-year-old male complained of pain in the left neck. A tumor of about 8 cm in diameter was detected by contrast CT in the region extending from the anterior to upper mediastinum. For definitive diagnosis, biopsy was performed under CT guidance, and the patient was diagnosed as having anaplastic carcinoma in the thymus (T4, N1, M0, stage IVb).

A long-term survivor of leiomyosarcoma around the right side of the base of the skull: effective radiotherapy combined with intra-arterial chemotherapy.

We report a rare case of a leiomyosarcoma that developed around the right side of the base of the skull in a 51-year-old woman. The patient consulted our hospital complaining of pain in the right side of her neck and upper right arm in August 1994. A leiomyosarcoma, originating around the right side of the neck and base of the skull was diagnosed.

[A case of advanced hypopharyngeal carcinoma successfully treated with superselective intra-arterial infusion of docetaxel].

Docetaxel is an excellent agent with a high antitumor effect for advanced/recurrent head and neck cancer. A 67-year-old male with advanced hypopharyngeal cancer (T3N2bM1: Stage IV) underwent two courses of superselective intra-arterial infusion of docetaxel and intravenous administration of CDDP and 5-FU. Using a coaxial technique, a microcatheter was placed in the feeding artery.
