Ten had acute DVT, and four were chronic. At first, a temporary filter catheter was introduced from the right subclavian vein, through which an infusion microcatheter(2.2F, 150 cm) was inserted. A pulse spray system (3F, 135 cm) was also employed. Urokinase (UK) was introduced locally into the thrombus by the pulse method (3,000 U/30 sec)and by continuous infusion (120,000-240,000 U/day). After complete clot dissolution, residual left common iliac vein narrowing in two patients (May-Thurner syndrome) was treated by means of PTA and placement of a Wallstent endoprosthesis. All patients continued to receive oral Warfarin.Results: Dramatic improvement of symptoms was noted in all patients after treatment. Complete thrombolysis was achieved in 11 patients (11/14: 79% success rate). Each of three incomplete cases had chronic DVT. The duration of filter insertion was a mean 16 days (range, 8-37 days)after administration of a mean 2.58 million U of UK (range, 0.24-5.04 million U). No major or minor complications occurred. At present, no patients show recurrent symptoms.Conclusion: Selective thrombolytic therapy performed by using a small-caliber catheter passed through a temporary vena cava filter is safe and effective.","PeriodicalId":19251,"journal":{"name":"Nihon Igaku Hoshasen Gakkai zasshi.

{"title":"[Brachytherapy for prostate carcinoma].","authors":"Atsunori Yorozu","doi":"","DOIUrl":"","url":null,"abstract":"This review aims to provide an overview of prostate brachytherapy and disseminate consensus guidelines formed by the American Brachytherapy Society. In Japan, permanent transperineal prostate brachytherapy with I-125 started in September 2003. Patients with high probability of organ-confined disease are appropriately treated with brachytherapy. Brachytherapy candidates with a significant risk of extraprostatic extension should be treated with supplemental external beam radiation therapy. The recommended prescription doses for monotherapy are 145 Gy. The corresponding boost doses after 40-50 Gy of external beam are 100-110 Gy. Dosimetric planning of the implant should be carried out for all patients before seed insertion. Post-implant dosimetry and evaluation must be performed on all patients. A dose-volume histogram of the prostate should be performed. The dose that covers 90% of the prostate volume, the percentage of prostate volume receiving 100%, 150%, and 200% of the prescribed dose, and the rectal dose and urethral dose should be reported. ABS recommends standardization of the reporting of brachytherapy-related prostate morbidity, including urinary, rectal, and sexual function. These morbidities should be correlated with the doses to normal tissues. High-dose-rate (HDR) brachytherapy with Ir- 192 has preceded seed implants in Japan. HDR has some theoretical advantages. We should develop techniques of both types of brachytherapy in Japan.","PeriodicalId":19251,"journal":{"name":"Nihon Igaku Hoshasen Gakkai zasshi.

Twenty-two patients (17 men and 5 women) with suspected myocardial infarction underwent breath-hold 3D late-enhanced viability examination at least 30 days after occurrence. All patients underwent a Tl-scintigraphy examination. First, 10 patients were examined without applying parallel imaging, then the next 12 patients were studied using parallel imaging. All 3D late-enhanced images at the short axis were acquired 10, 15, and 20 min after an injection of contrast agent, and both the long axis and the four-chamber views were acquired after 15 min. In quantitative analysis, the late-enhanced myocardial images at 10, 15, and 20 min showed higher contrast-to-noise ratios (CNR) in parallel imaging than those with no parallel imaging. During the time-intensity curve of the myocardium, no significant change was observed at 10 or 15 min; however, marked signal reduction was observed at 20 min. In diagnostic evaluation, images obtained with parallel imaging were superior to those without parallel imaging. In general, the application of parallel imaging reduces acquisition time with an expense of reduction in SNR. However, the breath-hold 3D late-enhanced images with parallel imaging showed no apparent SNR reduction. Furthermore, parallel imaging provided clear edge definition between the infarction and the normal region. The reduction of acquisition time with parallel imaging may be less susceptible to fast cardiac motion. In conclusion, breath-hold 3D delayed-enhancement MRI using parallel imaging was highly evaluated in our study and may show promise in clinical application.","PeriodicalId":19251,"journal":{"name":"Nihon Igaku Hoshasen Gakkai zasshi.
