  • Intradiploic epidermoid cysts of the cranium are rare, benign and slow growing lesion. However, these cysts may cause neurologic deficits due to mass effect. Intradiploic epidermoid cysts are thought to be derived from persistent ectodermal remnants present in the cranial bones during embryogenic development. Here, we report a case of an occipital intradiploic epidermoid cyst with posterior fossa extension. The patient developed intracranial hypertension associated with hydrocephalus due to aqueductal stenosis, and venous congestion secondary to compression of the torcular and the transverse sinus. The imaging studies included a computerized tomography[CT] venogram, which is essential for determining the pathophysiological mechanism of the clinical spectrum and for surgical planning. Near total removal was accomplished and the postoperative course was uneventful. Postoperative imaging studies demonstrated a reversal of the neural structures, but no patency of the sinus, which was presumably indicative of prolonged sinus stenosis. The patient gradually improved and was discharged free of symptoms.

  • Supravalvular aortic stenosis may be defined as an obstructive congenital deformity of the ascending aorta which originates just distal to the level of the origins of the coronary arteries It may be localized or diffuse. Enlargement of the aorta with a diamond-shaped patch of the noncoronary sinus of Valsalva was reported in 1961 by McGoon and associates But this reconstruction is asymmetric and the aortic obstruction may remain. In 1977, Dotty and associates reported the extended aortoplasty, the supravalvular ring was incised at two points in the noncoronary and in the right coronary sinuses of Valsalva closed with a tubular Dacron prosthesis of inverted Y-shape tailored to reconstruct the aorta We experienced three cases of the supravalvular aortic stenosis. The 11-year-old female and 4-year-old male with localized supravalvular aortic stenosis in William`s syndrome were operated with an inverted Y-shaped aortotomy toward the non-coronary sinus and the right coronary sinus and closed with "Hemashield`s collagen impregnated Dacron" tube graft, fashioned into "pantaloon" form patch. The 12-year-old male with localized supravalvular aortic stenosis and mitral insufficiency in William`s syndrome were operated with same procedure as two other patient above-mentioned for relief of supravalvular aortic stenosis and with mitral valve replacement. Postoperative course has been good.ourse has been good.

  • Dural arteriovenous fistula (DAVF) of the transverse sinus with ophthalmic manifestations in young children are rare. We reviewed two cases of direct AVF of the transverse sinus with ocular manifestations managed at our institution. The first, a 2.5 years old male child presented with left exophthalmos. Angiography revealed AVF between the occipital artery and the transverse sinus. The second, a 2 years old female child, complained of left exophthalmos. Imaging studies showed bilateral direct AVFs of the transverse sinus with bilateral dysmaturation of the sigmoid sinus. Transarterial embolization was done in both cases. Clinical and radiological follow up revealed complete cure. This report suggests that DAVF of the transverse sinus supplied by the external carotid branches can present with ophthalmic manifestations especially if there is distal venous stenosis or obliteration involving sigmoid sinus. Transarterial embolization using coils and liquid embolic agents could be safe and feasible to obliterate the fistula.

  • Congenital coronary arterial fistulae are the most prevalent hemodynamically significant congenital coronary artery malformations. Definition of congenital coronary arterial fistula is a direct communication between a coronary artery and the lumen of one of the four cardiac chambers or coronary sinus or SVC, pulmonary artery or pulmonary vein close to the heart. It is often associated with additional congenital or acquired heart disease. A 49 year old male patient was admitted with the chief complaints of anginal pain and exertional dyspnea for 9 months. He was diagnosed as the right coronary arterial fistula combined with right coronary arteriosclerotic stenosis and old inferior myocardial infarction by cardiac evaluation. The right coronary arterial fistula was communicated between the just distal portion of acute marginal branch and coronary sinus. The operative procedure was as followings; after suture ligation of fistula opening in the coronary sinus under beating heart, coronary arterial bypass grafting with saphenous vein was performed at the just proximal portion of the posterior descending branch under cardiopulmonary bypass. The postoperative course was uneventful and he was discharged without anginal pain at the 8th postoperative day.

  • Supravalvular aortic stenosis is relatively uncommon form of congenital heart disease and the most important lesion of this anomaly is various narrowing of the aortic lumen just above the sinus of Valsalva. We experienced a case of hourglass type of supravalvular aortic stenosis involving lcm from length from lcm above the sinus of Valsalva. The patient was associated with mental retardation, peculiar facies and dental anomaly. The diagnosis was confirmed preoperatively by retrograde left heart catheterization and left ventriculography. An incision was made in the ascending aorta and into the right coronary and noncornary sinus. Care was taken to protect the right coronary artery. A Y-shaped patch of Dacron was made to enlarge the stenotic portion of aorta. Postoperative pressure gradient between the aorta and left ventricle markedly reduced 36 mmHg in comparison with preoperative pressure gradient 150mmHg. The boy was discharged without any event.

  • Supravalvular aortic stenosis is an uncommon, congenital narrowing of the ascending aorta which originates just distal to the level of the ostium of the coronary artery. We conducted a successful surgical treatment in a 39 year- old female patient with a congenital supravalvular aortic stenosis and aortic regurgitation who did not show signs of William's syndrome. After we performed an inverted Y-shaped aortotomy toward the noncoronary sinus and right coronary sinus, pantaloon shaped prosthetic patch(Vascutek, Ino, USA) was used to repair the narrowing sinotubular junction. The aortic valve was replaced concommittently using Sorin Bicarbon 19mm. Her postoperative course was uneventful. The patient discharged at 9th postoperative day in good health.

  • The incidence of single coronary artery is extremely rare in a review of congenital anomalies of the coronary arteries. This 27-year-old male patient was referred for the evaluation of cardiac condition showing exertional dyspnea[NYHA class II-III] and chest discomfort for about 1 year. A complete catheterization study including angiogram disclosed large single coronary artery arising from left aortic sinus [Ogden classification L-4] associated with bicuspid aortic valvular stenosis and low grade supravalvular aortic stenosis. Calcified stenotic aortic valve was fully removed with caution and the 19mm St. Jude Medical valve was then implanted in the small nortic annulus. The patient had an uneventful recovery and was discharged on 13th postoperative day.

  • A modified procedure for the operative management of the corrected transposition of the great arteries with ventricular septal defect and pulmonary stenosis or atresia was performed in 4 patients. (age ; 18 months-9 years). The operation consists of a venous switch procedure (Senning), intraventricular baffling directing the blood flow from the morphologic left ventricle into the aorta via ventricular septal defect through the right ventriculotomy, and insertion of valved conduit between the morphologic right ventricle and the pulmonary artery. All the four patients had large non-restrictive ventriular septal defects and no evidence of significant mitral valve regurgitation. Both ventricles were well-developed. Three cases had pulmonary atresia, and the remainder had severe subpulmonic stenosis. Postperatively, all patients showed no findings of systemic or pulmonary venous obstruction withnormal sinus rhythm. One patient died of sepsis due to infection by Methicillin-resistant S. aureus on the thirteenth postoperative day. Follow-up is done on the survivors, and all of them are dong well with regular sinus rhythm, with their functional class I or II at 2 to 8 months after the operation.

  • Despite its known limitation in the diagnostic value, the electrocardiography is one of the most common and routine examinations in the management of the patients with cardiac problems. The clinical results of 291 patients who underwent isolated mitral valve replacement from October 1978 to June 1983 were already reported. Their electrocardiograms were studied to assess the value of electrocardiographic examination in following the patients after valve replacement. The patients were divided into 5 groups beforehand according to the types of valve lesion on the bases of preoperative diagnosis and operative findings: Groups I: stenosis, I1: stenosis-dominant mixed, II1: equally mixed, IV: insufficiency-dominant mixed, and V: insufficiency. Their preoperative cardiac rhythm was sinus in 39.2% and atrial fibrillation in 59.1% of the patients. Seventy-three [42.4%] of the patients with atrial fibrillation gained sinus rhythm after operation, occurring in 67 from the day of surgery, and 42 returned to atrial fibrillation while 37 kept sinus rhythm at the follow-up end [mean follow-up period, 13.4\ulcorner1.4 months]. The P waves on the electrocardiograms of the preoperative sinus rhythm in 114 patients were normal in 5.3% and the findings of left atrial enlargement in 94.7% of the cases. They were normal in 42.1% and the findings of left atrial enlargement in 57.9% of the 140 patients with sinus rhythm at the follow-up. The preoperative major chamber enlargement was the right ventricle in Group I while it was the left ventricle in Group V, and it was in-between in Groups II-IV. The postoperative regression of the findings in ventricular enlargement was statistically significant only in Groups I and V. These results may suggest the importance of the serial electrocardiograms in following the patients with mitral valve replacement on the bases of outpatient. The electrocardiographic follow-up data were presented in patients with suspected or proved tissue valve failures.

  • Supravalvular aortic stenosis may be defined as an obstructive congenital deformity of the ascending aorta which originates just distal to the level of the origin of the coronary arteries. It may occur in several different anatomical form. Three type have been described; the hourglass, the hypoplastic and the membranous type, each term identifying the gross characteristic of the lesion causing by the aortic obstruction. Non cardiovascular condition commonly associated with supravalvular aortic stenosis are mental retardation, facial anomalies, hypercalcemia, etc. The diagnosis can be established preoperatively by left heart catheterization and selective angiography. Recently, we experienced a case of multiple localized supravalvular aortic stenosis involving, just above the sinus Valsalva and just proximal of the innominate artery. The surgical correction which was performed by a vertical incision across the each narrowing of aorta with replacement of diamond shaped double velour Woven Dacron patch under the CPB. He was discharged without any event.
