Preoperative embolization of hypervascualr brain tumors is known to be an effective method to reduce intraoperative bleeding and to reduce the operative difficulty. The most commonly tumor vessels are branches of the external carotid artery, which are frequently embolized as a preoperative procedure. However, branches from the internal carotid artery, such as the ophthalmic artery, tentorial artery, or cortical branches sometimes feed tumors, but there are some limitations of embolization of branches from the internal carotid artery. In addition, hypervascular tumors are rarely associated with neoplastic aneurysms. Their possible role in producing massive intraoperative hemorrhage has been well recognized. We describe the successful embolization of the tumor vessels from branches of the internal carotid artery and their neovascularization.

Discrete subaortic stenos is one of the subtype of congenital left ventricular outflow obstruction and frequently associated with other defect such as ventricular septal defect, coarctation of the aorta, inturrupted aortic arch, double-chambered right ventricle and atrioventricular canal. It is progressive disease from the neonatal period and can be a cause of secondary endocarditis or aortic regurgitation. The authors have experienced a case of discrete subaortic stenosis without other associated lesions in 8 years old male patient who has complained chest discomfort. The diagnosis was established by the findings of echocardiography and cardiac catheterization. We report this case with a brief review of related literatures.

This study presents data on the externally received doses for radiation workers who used the Korea Radioisotope Association's personal monitoring and dose record keeping service from 1984. Distributions of annual dose by age of worker and occupational category were given. The number of radiation workers registered was 23,257 in 1997. The trend of the number of radiation workers and their annual doses increased since 1984. The measured radiation dose were generally low. The collective annual dose and the mean annual dose were 33.45 Sv and 1.44 mSv, respectively. Very few workers(0.5%) exceeded 20 mSv(2 rem) and only 1 exceeded 50 mSv, the legal limit for dose.

Recent advances in stent technology have allowed the introduction of more flexible stents that may be tracked more easily in the intracranial vessels. We present a patient with improved cerebral perfusion as assessed by single-photon emission computed tomographic(SPECT) scan after stent-assisted angioplasty for symptomatic middle cerebral artery stenosis. A 72-year-old man presented with multiple episodes of transient verbral disturbance and right-sided motor weakness for 5 months despite treatment with aspirin and clopedigrel. Angiography revealed a 50% to 60% stenosis of the left middle cerebral artery. 99m Tc-exametazime-SPECT scan demonstrated decreased cerebral blood flow in the left cerebral hemisphere, particularly in the left middle cerebral artery territory. The patient was recommended a stent-assisted angioplasty for middle cerebral artery stenosis. The patient underwent uncomplicated stenting with S-660 2.5- by 9-mm stent(Arterial Vascular Engineering, Santa Rosa, CA) of the left middle cerebral artery, with excellent angiographic results. Follow-up brain SPECT scan showed markedly improved perfusion. Stent-assisted percutaneous transluminal angioplasty can provide a favorable clinical course as well as improved cerebral perfusion for a patient with middle cerebral artery stenosis. Long-term follow-up data and additional clinical experience are required to assess the durability of this procedure.
