Successful percutaneous transluminal angioplasty (PTA) of an internal mammary artery graft was performed in a 40 year old male patient who had recurrent angina soon after bypass surgery. Coronary angiography showed total occlusion of proximal portion of the left anterior descending artery and normal right coronary artery. Angiography of the left internal mammary artery graft revealed a tight stenosis (90% diameter narrowing) in the mammary artery at its insection into the left anterior descending artery.Angiography after the angioplasty demonstrated a widely patent graft (residual stenosis 10%) and translesional pressure gradient was 10 mmHg.

Chondroblastoma is a rare primary bone tumor which originates from cartilage, and represents approximate 1% af all bone tumor. The chondroblastoma arises most frequently from the epiphysis of the long bones with the humerus being the commonest site. It afflicts usually the young under 25 years with greater incidence in male. As there is no cartilage cell on craniofacial bone which is mainly fromed by intramembranous ossification, the chondroblastoma on the craniofacial bone is extremely rare. But the chondroblastoma recurred frequently in craniofacial bone when the mass is excised incompletely or curretted and, as the tumor has the outstanding ability of local invasiveness, it destructs the adjacent bone. In addition, it is difficult to diagnose differentially from sarcoma or giant cell tumor histopathologically. Due to the entities described above, it is necessary to remove the entire tumor mass as complete as possible, to treat with radiation pre or postoperatively for preventing from recurrence, and to observe for a long time. The chondroblastoma on temporal bone is rare and is difficult to diagnose and treat successfully. So we'd like to present a case of chondroblastoma which was originated from temporal side of TMJ with literatural review.

To determine factors involved in left ventricular aneurysm formation after transmural anterior myocardial infarction, 74 patients with a first myocardial infarction who underwent cardiac catheterization within 6 weeks of infarction were evaluated.Patients were divided into four groups depending on the status of the left anterioe descending artery(LAD) and the presence Group I(n=15);aneurysm with occluded LAD, Group II(n=16);no aneusrysm and occluded LAD, Group III(n=18);aneusrysm and patent LAD, and Group IV(n=25);no aneusrsm with patent LAD. Neither age, sex nor risk factors for coronary disease correlated with aneusrysm formation,but the duration of chest pain in patients with previous angina was significantly longer in group II(no aneusrysm with occluded LAD) compared with other groups(P<0.01). Single vessel disease was more commom in Group I and III(aneusrysm) compared with II and IV(no aneusrysm)(P<0.06). Collateral blood supply was more frequently observed in Group I and II(occluded LAD) compared with Group III and IV(patent LAD)(P<0.01) and was slightly less in Group I(aneusrysm) compared with Group II(no aneusrym)(P<0.07). Delta area decreasing rate of the left ventricle was significantly lower in Group I and III(aneusrysm)compared with Group II and IV(no aneusrysm)(P<0.01). Single vessel disease in assocition with poor collateral circulation tends to be a determinant of left ventricular aneusrysm formation after anterior myocardial infarction.

Although halothane is one of the most widely used inhalational anesthetics, it may cause postanesthetic complications such as halothane hepatitis. Halothane hepatitis has been reported lintermittently since 1958 with variable incidence. Changes in hepatic functions by halothane hepatitis are usually mild and reversible but they may be fatal it the patient had already shock, sepsis, massive blood transfusion, previous hepatic disease, hypoxia or induction of microsomal enzyme system. Hepatitis due to blood transfusion has high incidence especially in Korea where 10~20% of all population has vital hepatitis. Most of transfusion hepatitis is also mild but it may progress to chronic condition and eventually death. We experienced 2 cases of fulminant hepatitis after operation. Several factors such as massive whole blood transfusion, upper abdominal trauma, inhalational anesthetic agent, induction of microsomal enzyme system and shock might be attributed to development of the fulminant hepatitis.

Isolated masseter spasm after succinylcholine administration is a rare abnormal response, but has been reported by a number of authors and is considered and early manifestation of malignant hyperpyrexia. We experienced a isolated masseter spasm after a small dose of succinylcholine administration in a facial palsy patient of central type due to brain tumor. It was likely that the intensity of this spasm was dose dependent to the amount of succinylcholine administration, and the spasm was prevented by pretreatment of nondepolarizing muscle relaxant. Anesthesia was performed safely for about 5 hours with nitrous oxide and halothane. We considered that this spasm was due to supersensitivity appearing at the denervated muscle.

Epidural nerve block is the most widely practiced procedure in the pain clinic. Accidental dural puncture during epidural nerve block also has been associated with postdural puncture headache and total spinal anesthesia. Especially, total spinal anesthesia is the most serious complication of epidural nerve block and can lead to a life threatening conditions. We have experienced two cases in whom total spinal anesthesia occurred during epidural nerve block for neck and lower back pain control. Immediately after epidural nerve block, the patients became unresponsive and apneic with loss of muscle tone in all extremity. We performed resuscitations and about 3 hours later the patients recovered completely without any complication.

Transscleral and transpupillary diode lasers are methods of cyclophotocoagulation used to lower intraocular pressure by reducing aqueous humor production through ciliary ablation. When compared with the neodymium[Nd]-YAG, the diode laser has characteristics of lower transmission rate through the sclera and more absorption by pigment or melanin in the ciliary body, therefore the transpupillary method might be more effective in Asians who have greater ciliary body pigmentation than caucasian. We compared the efficacy of diode laser transpupillary and transscleral cyclophotocoagulation on lowering of the intraocular pressure in Asian patients. We performed transpupillary[group 2, n=9]and transscleral [group 1, n=21]diode laser cyclophotocoagulation in medically uncontrolled glaucoma patients. Preoperative mean intraocular pressures were 35.0 +/-13.1 millimeters of mercury[group 1]and 31.8 +/-9.8 millimeters of mercury[group 2], respectively. Postoperative mean pressure were 23.0 +/-14.8 millimeters of mercury[group 1]and 24.8 +/-9.9 millimeters of mercury [group 2], respectively. The intraocular pressure decreased in both groups[p=0.002 group 1, p=0.025 group 2]with statistical significance. Complications were phthisis, bullous keratopathy[group 1]and corneal edema[group 2]. Both transscleral and transpupillary diode laser cyclophoto-coagulation may be performed safely to decrease intraocular pressure. Retrospective studies and long term follow up are further needed to determine the safety of laser cyclophotocoagulation.
