Intracranial calcification is known to be a physiologic phenomenon and is often seen in brain CTs of patients visiting the emergency department. The pattern of a calcified lesion may be related to the pathologic condition, and calcified lesion itself may cause neurologic symptoms. The causes of pathologic intracranial calcification are infection, brain tumor, vascular disorder, endocrinologic disorders, and genetic disorder associated with calcium metabolic defects. The most common sites of intracranial calcification are the basal ganglia, subcortical tissue of the cerebrum, the thalamus, the choroid plexus, and the dentate nucleus of the cerebellum. The diagnosis of pathologic calcification can be done by using brain CT or MRI, and pathologic calcification should be differentiated from other causes of calcification by using laboratory data. We report and discuss a case of extensive intracranial calcification with idiopathic hypoparathyroidism.

PURPOSE: The aim of this pilot study was to determine the relationship between the beta-fibrinogen G/A-455 single nucleotide polymorphism and the risk of ischemic stroke in Korea because there are racial differences in polymorphisms and Koreans have never been studied before. METHODS: From March to September 2003, we compared 80(male : female=1.2 : 0.8) patients who were diagnosed with ischemic stroke at Kyung Hee university hospital emergency center had been to 150 control subjects. The genotypes of the beta-fibrinogen G/A-455 polymorphism were confirmed by using the polymerase chain reaction (PCR) followed by HaeIII restriction enzyme digestion. RESULTS: The results showed that the patient group had a much higher rate of heterozygotism (GA or AG). A statistical analysis of the genotype frequency showed chi2 to be 6.24, indicating a significant difference between the patient and the control groups (p=0.044). For the allele frequency, the odds ratio was 1.88(95% CI 1.16-3.04), indicating a significant difference between the two groups, and also allele frequency in ischemic stroke patient with or without hyperfibrinogenemia, male sex and smoking history showed odds ratio to be 2.38(95% CI 1.26~4.49), 1.78(95% CI 1.01~3.14)and 1.94(95% CI 1.12~3.35) indicating significant difference. CONCLUSION: The high rate of polymorphisms of the AA genotype of beta-fibrinogen G/A-455 in ischemic stroke patients in our study leads us to the belief of the possibility that beta-fibrinogen G/A-455 polymorphisms in males with a smoking history and hyperfibrinogenemia, if found in advance, could lead to an improved prognosis and reduced clinical expenses by allowing early diagnosis and preventive management.

Mitral regurgitation originating from mitral valve leaflet perforation secondary to blunt chest trauma is a rare condition. The mechanisms related with valvular injury are rapid acceleration- deceleration movements of the thorax, compression of the heart between the sternum and vertebrae during early systole or late diastole, and abrupt increase of the intrathoracic pressure followed by cardiac rupture. Transesophageal echocardiography (TEE) is a recommended diagnostic tool and is superior to transthoracic echocardiography (TTE) for diagnosing valvular lesions. Valvular injury causing sudden and severe mitral regurgitation will lead to congestive heart failure and death without operative correction. A high index of suspicion with appropriate diagnostic methods will provide a diagnosis and allow the possibility of operative correction. We report the case of a 45-year-old man with delayed presentation of traumatic mitral valve perforation and review previous reports of blunt traumatic mitral valve injury.

Primary cardiac tumors are rare and about 20~25% of primary cardiac tumors are malignant. Moreover, primary malignant mesenchymoma of the heart is extremely rare. Recently, we have experienced two cases of cardiac malignant mesenchymoma. In the first case, malignant mesenchymoma which was originated from the posterior wall of the left atrium obstructing the mitral orifice was revealed pathologically in a 61-year-old woman with mitral regurgitation. The mass, which was 2.7 X 3.7cm in size on the posterior wall of left atrium, was extended to the posteromedial commissure and annulus of the mitral valve. The mass was resected partially without excision of the left atrial free wall. She was discharged after 30 days without any problems and she received chemotherapy and followed up for 19months. The second case was a 4 X 5cm in size, friable, yellow-whitish multilobulated mass in the left atrium which was originated from the left lower pulmonary vein. Multiple minor tumor nodules were found in the wall of the left atrium and the posterior leaflet of mitral valve. Partial mass excision and mitral valve replacement were performed.

PURPOSE: To evaluate the diagnostic efficacy of gastric air filling during DSA-hepatic arteriography of the left lobe in overcoming the pitfalls caused by accessory left gastric artery and left hepatic artery from left gastric artery. MATERIALS AND METHODS: In a prospective study, standard hepatic arteriogram and hepatic arteriogram after ingestion of an effervescent agent were performed in 22 patients with anatomic variation of the celiac axis. The anatomic variations were accessory left gastric artery in 15 patients and left hepatic arteryfrom left gastric artery in seven. RESULTS: Hepatic arteriogram after ingestion of an effervescent agent was excellent in differentiating nodular stomach staining from hepatic tumor staining in the left hepatic lobe in patients with accessory left gastric artery, and for evaluation of the left hepatic lobe when this was obscured by stomach staining. CONCLUSION: Hepatic arteriogram after ingestion of an effervescent agent is a simple and safe method for overcoming angiographic pitfalls due to anatomic variation.

PURPOSE: To evaluate the usefulness of percutaneous transhepatic biliary drainage (PTBD) tract dilatation using a Nipro set. MATERIALS AND METHODS: We dilated 28 percutaneous biliary drainage tracts up to 18F ; 26 procedures involved PTBD, and two, cholecystostomy. A Nipro set was used for dilatation, the purposes of which were stone removal (n=18) and choledochoscopic biposy (n=10). For dilatation, local anesthesia was used in all cases. RESULTS: In all patients, tract dilatation was successful. In 21 of 28 cases, dilatation of the right PTBD tract was involved, and in five of 28, dilatation of the left tract. In two cases, tract dilatation was done in cholecystostomy tracts. Complications encountered were pain (n=17), bradycardia (n=2), hemobilia (n=2), bleeding (n=1)and fever (n=1). CONCLUSION: In choledocoscopy, tract dilatation using a Nipro set is safe and simple.

BACKGROUND: Percutaneous transluminal coronary angioplasty(PTCA) for long coronary lesion is known to be associated with low success rate,suboptimal outcome,high complication and restenosis rates. Here we report the early clinical and angiographic results of long coronary stent implantations for long coronary lesions. METHOD: We analyzed the clinical,angiographic features and early results after stent implantations in 46 patients who were implanted long coronary stent(> or =20mm in length)among 174 stented patients at Chonnam University Hospital from Jan.through Nov.1996. RESULT: 1) Age was 59+/-7(35-78) years,and sex ratio was 2.5:1(33 male:13 female). clinical diagnosis was as follows; 24 patients with unstable angina, 21 with acute myocardial infarction, 1 with stable angina and 6 with old myocardial infarction. Left ventricular ejection fraction by left venriculogram was 58+/-10(27-87)%. 2) Involved numbers of vessel were single in 27 patients, two in 14 patients, and three in 5 patients. Target stented coronary arteries were 28 left anterior descending arteries, 17 rigtt coronory arteries, and 1 left circumflex artery. Morphologic types of target lesions were type C in 26 patients, type B2 in 20, and diameter stenosis(DS) was 76+/-13%, minimal luminal diameter(MLD) 1.0+/-0.3mm, length 21+/-6(10-38)mm. Indications for stent were 28 denovo lesions, 10 restenoses, 5 suboptimal PTCAs and 3 bailout procedures. Twenty six Microstents 2, 15 Wallstents, 4 Freedom stents, and 1 Wictor stent were used. Stent diameter was 3.2+/-0.3(2.5-5.0)mm and length 30+/-3(20-49)mm, stent diameter/reference diameter(RD) ratio 1.0+/-0.1, and stent minus lesion length 9.0+/-3.7mm. 3) Stents were deployed successfully in all 46 patients. No procedure-related death, myocardial infarction, emergency bypass surgery, and laboratory evidences of acute or subacute stent thrombosis were observed. 4) DS was decreased to 3.5+/-7.5%, MLD was increased to 3.2+/-0.3mm(p<0.0001, respectively). Acute gain was 2.2+/-0.4mm(71.8+/-15.6%,p<0.0001). CONCLUSION: We observed high success rate without major complications in long stent implantations for long coronary arterial lesions. Long-term follow-up should be required to prove long coronary stent as a better treatment modality to reduce acute complications and late restenosis.

When any part of the pacemaker system is infected, all pacemaker hardware should be removed, because reinfection rates of 51% to 77% have been noted in patients whose infected pacemaker system has been only partially explanted. The removal of infected leads during cardiopulmonary bypass prevents mechanical injury as well as the spread of infection and vegetation. We report one case of endocarditis by staphylococcus aureus with infected transvenous pacing lead which was migrated into the heart from the left subclavian vein. We removed the migrated pacing lead and vegetation under cardiopulmonary bypass.

Severe, occlusive spiral dissection during diagnostic coronary angiogram is very rare. A 41-year old female patient was admitted because of chest pain at night. Her left coronary angiogram revealed no significant stenosis with diffuse luminal narrowing. Immediately after right coronary artery (RCA) injection, sudden occlusion of middle RCA was noted, which was not improved despite multiple injections of intracoronary nitrate. The patient complained of severe chest pain and ST segment elevation was observed on electrocardiogram monitoring. After wiring into true lumen of RCA, distal flow was improved and intravascular ultrasound revealed spiral dissection flap extending from proximal to middle RCA. Final coronary angioram showed patent RCA with spiral dissection and good distal flow into the distal RCA. The patient had no clinical events during 2-month clinical follow-up.
