Pulmonary endomertiosis is a rare disorder with the typical symptom of hemoptysis during menstruation (catamenial hemoptysis). We report a case of a 19-year-old woman, gravida 0, with 3-month history of catamenial hemoptysis which was confirmed with chest computed tomography. She was treated by means of thoracoscopic wedge resection for the right lesion and fuperior segmental resection through the left thoracotomy, successively. Preoperative fluoroscopy-guided hooking for thoracosopic target lwsion was helpful in circumstances with one lung anesthesia. Four months of follow-up after an uneventful discharge revealed out no recurrence of catamenial hemoptysis in symptoms and images.

The incidence of the distal anterior cerebral artery(DACA) aneurysm comprises about 2-6% of all intracerebral aneurysms. Because of the low incidence, unique anatomies of the distal anterior cerebral arteries and some technical difficulties in surgery, these aneurysms present such challenge to neurosurgeons. Presently, early surgery using interhemispheric approach is preferred. The auhtors experienced six patients with DACA aneurysms in 130 consecutive intracerebral aneurysms surgically treated between May. 1994 and Dec. 1997. The patients received operations within five days from the ictus, except one patient because of symptomatic vasospasm. The surgical approaches were all unilateral interhemispheric approaches. During the operations, infusion of large amount of mannitol and CSF volume removal were applied, although there were few difficulties in the interhemispheric dissections, the outcomes of the patients were excellent in three, good in three. The authors suggest that early operative interventions using unilateral interhemispheric approach without generous craniotomy can improve the outcomes of the patients with ruptured DACA aneurysm.

OBJECTIVE: The author conducts a retrospective study to analyze long-term outcome and complication of LINAC radiosurgery for cerebral arteriovenous malformation(AVM). METHODS: We performed a detailed long-term follow-up study of 31 patients who could be followed up more than 2 years, with AVM treated by LINAC radiosurgery during January, 1996 to July, 2001. At the time of radiosurgery, the mean age was 47 years (range: 13-68). The median follow up period after radiosurgery was 27.2 months (range: 24-36). In all patients, AVM were completely covered with a 50~90% isodose line. The margin dose delivered by the LINAC was 14~28Gy(mean: 20.9Gy) at the periphery. RESULTS: Angiographic complete obliteration rate was 74.2% at 2 years after radiosurgery. Hemorrhage occured in 2cases(6.5%) at 12 and 14months after radiosurgery retrospectively, and 1patient died. Radiation related complication was developed in 1case(3.2%). CONCLUSION: LINAC radiosurgery is safe and effective in the treatment of cerebral arteriovenous malformation.

The common cause of tracheoesophageal fistula(T-E fistula) after tracheal intubation is ulceration and necrosis of the posterior wall of trachea by compression pressure generated by cuff. We experienced a young woman sustaining a T-E fistula which was found on the 12th day of intubation for cardiopulmonary resuscitation. Because spontaneous closure of the fistula is far uncommon, operative closure should be aimed for and should be done as soon as diagnosis is conformed. We delayed operative closure because of poor general condition of the patient. In spite of delayed reconstruction, the tracheal reconstruction itself was successful, but the patient died of peritonitis induced sepsis on the postoperative 41th day.

For the treatment of carotid-cavernous fistula, detachable balloon occlusion(DBO) is the method of choice. When it fails, or when the fistula is incompletely occluded, alternative treatment methods include direct surgery and internal carotid artery occlusion at the proximal and distal portion of the fistula. Before ligation or occlusion of the internal carotid artery, however, coil embolization should be considered, as this preserves patent internal carotid artery. The authors used DBO in a 22-year-old male patient with carotid-cavernous fistula which developed after head injury. During the procedures the fistula was partially obstructed by one detachable balloon. In spite of several attempted occlusions with a second balloon, this could not be introduced into the small remnant fistula hole. The second stage of intervention involved embolization with a Guglielmi detachable coil(GDC) ; this was successfully introduced into the partially obstructed fistula, which was thus completely occluded, and the patient's clinical symptoms improved. In this case, GDC emboization was an effective tool for the treatment of carotid-cavernous fistula incompletely occluded by a detachable balloon.

PURPOSE: To investigate the error tendency between preoperative expected refraction and postoperative manifest refraction based on anterior chamber depth (ACD) and axial length (AXL) in cataract surgery cases and to report how ACD and AXL affect determination of intraocular lens (IOL) power. METHODS: We retrospectively studied 82 eyes of 62 patients who underwent cataract surgery in our hospital between August 2008 and January 2009. Anterior chamber depth and AXL were measured using IOL Master(R), and IOL power was calculated using the SRK II and SRK/T formulae. Patients were divided into three groups based on ACD and into another three based on AXL. Refractive error (RE) was analyzed one month after surgery. RESULTS: Though the RE of each group showed a tendency for hyperopic shifts, only those obtained with the SRK/T formula showed statistically significant differences between groups (p<0.05). Using the SRK/T formula, we found that an increasing AXL was associated with an increased hyperopic shift. This was more pronounced in those with shallow ACD (<2.5 mm), though the difference was not statistically significant. Similarly, an increase in ACD was associated with an increased hyperopic shift, and this difference was more pronounced in those with short AXL (<22.5 mm), and this time the difference was statistically significant. CONCLUSIONS: As ACD and AXL significantly affect RE, both should be considered when investigating postoperative RE tendency and when determining IOL power. Postoperative RE will be greatly affected by a short AXL or a shallow ACD, and therefore these factors should be considered in IOL power determination.

OBJECTIVES: Pituitary apoplexy is a well-described clinical syndrome resulting from pituitary hemorrhage, hemorrhagic infarction, or infarction, almost invariably occurring in the presence of an adenoma. We analyzed pituitary apoplexy with an emphasis on clinical presentation, pathology and predisposing factors. METHODS: We reviewed 35 histologically proven pituitary adenomas, operated from January 1995 to August 1999, to select 8 cases which showed clinical or operative findings compatible with pituitary apoplexy. These patients were analyzed in terms of symptom and sign, hormonal status, and predisposing factors, pathologic findings. RESULTS: Among 35 surgically treated tumors of the pituitary gland, 8 cases(23%) were diagnosed as pituitary apoplexy. The pathologic findings revealed hemorrhage(7 cases) and infarction(1 case) of pituitary adenomas. One case had predisposing factor of appendectomy. The most common presenting symptom and sign were sudden severe headache and visual disturbance. CONCLUSION: We treated pituitary apoplexy surgically and obtained good outcomes. Pituitary apoplexy due to massive infarction of the pituitary gland is very rare condition but surgical treatment by trans-spheniodal surgery showed a good result.

Mazabraud's syndrome, the etiology of which is unknown, is a rare benign disease, characterized by theas-sociation of intramuscular myxoma and fibrous dysplasia of bone, usually polyostotic. We describe a case ofMazabraud's syndrome in which with two intramuscular myxomas of the forearm were associated with polyostoticfibrous dysplasia.
