  • Stellate ganglion block (SGB) is applicated frequently to increase the blood flow and to reduce the pain in head, neck and upper extremity. The effects of SGB are able to be estimated by clinical signs and symptoms of Horner's syndrome, skin warmth, anhydrosis, etc. The effects are also estimated by sympathetic function and the blood flow. Blood flow velocities and pulsatility indices of common carotid,d axillary, brachial and radial artery were measured by Doppler flowmeter after SGB with 1% lidocaine at C6 level. Blood velocities of all arteries were increased and pulsatility indices of all arteries were decreased. This results suggest that SGB increase the blood flow of head and upper extremity and Doppler flowmeter is a good indicator of the effects of SGB.

  • Thirteen patients with cyanotic cardiac malformations having more complex intracardiac defects, hemodynamics and operative procedures than ones in Tetralogy of Fallot undertaken total surgical corrections from July 1981 to August 1985. The cases of corrective surgery for complex cardiac malformations were 3.9% of all congenital cardiac malformations and 12.6% of cyanotic cardiac malformations. Six patients died within 30 days after surgery. So operative mortality was 46%; Transposition of the great arteries, two of 4 patients, due to low cardiac output syndrome and tracheal bleeding ; Univentricular heart, one of 3 patients, due to bleeding; Corrected transposition of the great arteries, one of 2 patients, due to acute heart failure; Tricuspid atresia, one of 2 patients, due to low cardiac output syndrome; Double outlet right ventricle, one of single patient, due to respiratory failure. The cases of surgical correction for complex cardiac malformations are progressively increasing in numbers. The more accurate evaluation of anatomical condition and hemodynamics in preoperative diagnosis, studies on applicable surgical procedure and perioperative care of patients are necessary in the improvement of clinical and surgical results.

  • A 18-year-old female underwent surgical correction of tricuspid atresia and complete transposition of great arteries combined with atrial 8 ventricular septal defect and pulmonary stenosis. After the transection of main pulmonary artery just above the pulmonic valve, proximal portion of main pulmonary artery was closed with running suture and distal portion of main pulmonary artery anastomosed with right atrial appendage without valve insertion. Atrial septal defect was closed with running suture. Postoperative course was uneventful and she discharged on 18th postoperative day. Her condition is in very good until present. Modified Fontan`s operation without valve placement [in the condition of low pulmonary vascular resistance and good left ventricular function] may has a good result.

  • A seventeen-month-old male baby, who had received conventional biventricular repair for congenitally corrected transposition of the great arteries, underwent excision of supratricuspid ring. Although tricuspid valve annulus was marginally small on direct inspection in the operating theater, circumferential excision of supratricuspid ring alone completely relieved the right ventricular inflow obstruction.

  • A multistage plan and multidisciplinary approach are the keys to successful repair in patients with pulmonary atresia (PA) with ventricular septal defect (VSD) and major aortopulmonary collateral arteries (MAPCAs). In this article, we present a multidisciplinary approach adopted to treat a patient with PA with VSD and MAPCAs associated with left pulmonary artery interruption.

  • We report on a diabetic 52-year-old man who complained ocular floating sensation, headache and dizziness, in whom a left parieto-occipital dural ateriovenous fistulas [DAVFs], fed by bilateral superficial temporal arteries and occipital artery, drained into the cortical vein of the left parieto-occipital convexity. Because the patient's chief complaint was ocular symptom for diabetic retinopathy, we initially didn't consider an DAVFs until brain magnetic resonance imaging [MRI] was done. Diffusion-weighted brain MRI revealed acute cerebral infarction and microhemorrhage in the lesion. Transarterial embolization with mixture of glue and lipiodol obliterated the DAVFs completely. Although the DAVFs fed by multi-arteries, the fistulous portion has been disappeared after embolization via an only left occipital artery Endovascular embolization of the fistula led to symptomatic improvement, except ocular discomfort.

  • Aortopulmonary window (APW) is a rare cardiac anomaly that was reported to occur in only 43 cases over 33 years at a large-volume cardiac center. It can present as an isolated anomaly or in combination with another cardiac anomaly. The surgical technique for APW has evolved from simple ligation to separation of the 2 great arteries. However, because of the rarity of APW, there is no standard surgical treatment for this disease entity. Herein, we present successful aortic reconstruction using a main pulmonary artery flap after separation of the 2 great arteries in a neonate with isolated APW.

  • Platycodon grandiflorum and Glycyrrhiza uralensis contain several bioactive compounds, such as saponin, oleanolic acid, and flavone. P. grandiflorum and G. uralensis have traditionally been used to treat disorders related to blood pressure, diabetes, and counteracting poison, and they have antinociceptive and antiinflammatory properties. However, the validity of complex saponin's vasodilatory effect has not been scientifically investigated. Therefore, this study explores the vasodilatory effect of complex saponin extracted from P. grandiflorum and G. uralensis mixture extract on rabbit carotid arteries. To this end, arterial rings with intact or damaged endothelium were used in an organ bath experiment and contracted by endothelin. Complex saponins, the major active constituents of P. grandiflorum and G. uralensis mixture extract, exhibited a moderate vasodilatory effect on the rabbit's basilar arteries. Therefore, treatment with complex saponin extracted from P. grandiflorum and G. uralensis mixture extract may selectively accelerate cerebral blood flow through basilar arterial dilation. Overall, the findings suggest that the extracted complex saponins can serve as vasodilator sources.

  • Double outlet right ventricle (DORV) is a relatively common congenital heart disease in which both great arteries are connected completely or predominantly to the morphologic RV. Unlike other congenital heart diseases, DORV demonstrates various anatomic and hemodynamic subtypes, mimicking ventricular septal defect, tetralogy of Fallot, transposition of the great arteries, and functional single ventricle. Because different surgical strategies are applied to different subtypes of DORV with ventricular septal defects, a detailed assessment of intracardiac anatomy should be performed preoperatively. Due to high spatial and contrast resolutions, cardiac CT can provide an accurate characterization of various intracardiac morphologic features of DORV. In this pictorial essay, major anatomic factors affecting surgical decision-making in DORV with ventricular septal defects were comprehensively reviewed using three-dimensional cardiac CT data. In addition, the surgical procedures available for these patients and major postoperative complications are described.
