D uring the last 5 years, there has been a tremendous interest in the development of new devices for percutaneous treatment of peripheral and coronary artery obstructive arterial disease.1 As during the development of balloon angioplasty, many of these devices were first tested in peripheral arteries before their use in coronary arteries. Although this stage of new device development may no lon...

Balloon dilatation angioplasty was successfully performed in five patients (ages 18 months to 17 years) with discrete aortic coarctation. The catheter size was No. 8F or 9F. Selection of balloon diameter was based on angiographic measurements of the aorta determined proximal and distal to the coarctation site. A 10 sec inflation-deflation cycle at 6 to 8 atmospheres (90 to 120 psi) was performe...

OBJECTIVE To investigate the release of chemoattractants after myocardial ischaemia during balloon angioplasty. DESIGN Sampling of femoral arterial and coronary sinus blood before and immediately after the first balloon inflation during angioplasty. In a study group of 16 patients the balloon was kept expanded for two minutes, whereas in a control group of eight patients the first balloon inf...

OBJECTIVES This study evaluated the long-term impact of endoluminal low power red laser light (LPRLL) on restenosis in an atherosclerotic rabbit model. BACKGROUND Despite widespread application of balloon angioplasty for treatment of coronary artery disease, restenosis limits its clinical benefits. Restenosis is a complex process and may be partly attributed to the inability of the vascular e...

We report 5 cases of non-Hodgkin lymphoma of the small intestine (S-NHL)treated with emergency operation.These cases showed three reasons for emergency operation:[1]massive hemorrhage with shock before diagnosis of S-NHL(Case 1),[2]obstruction of the small intestine before and during chemotherapeutic treatment for S-NHL (Cases 2 and 3),and[3]spontaneous perforation with peritonitis before diagn...

Background: Accelerated partial breast irradiation via interstitial balloon brachytherapy is a fast and effective treatment method for certain early stage breast cancers however skin, chest wall and Lung doses are correlated with toxicity in patients treated with breast brachytherapy.Objective: To investigate the percentage of the dose received by critical organ (skin), thermoluminescence detec...

Balloon flower (Platycodon grandiflorum) is a kind of mountain herbs whose roots have restorative properties and the cultivating acreage of balloon flower has been steadily increasing in Korea. More frequent rain and high amount of rainfalls as a result of climate changes predisposed balloon flower to the outbreaks of root rot at high-density cultivation area in recent years. Root crowns were u...
