  • Clinical application of captopril renal scintigraphy in Takayasu's arteritis.
    Clinical nuclear medicine, 1993
    Co-Authors: Antonio G. Balingit, Jay H. Anderson

    Takayasu's disease (pulseless disease) is an uncommon chronic Inflammatory disease primarily affecting the medium and large Arteries, with a strong predilection for the aortic arch and its branches; hence, it sometimes is referred to as aortic arch syndrome. The etiology is unknown, although a systemic immunologic process seems most likely. About half the reported cases also revealed involvement of the pulmonary and renal arterles. The involvement is more marked in the origin of the vessel than distally. Although it is more common among Orientals, its distribution is worldwide, without racial boundary. A case is presented in which captopril renal scintigraphy and digital subtraction angiography were used to show renal artery stenosis as the cause of the patient's hypertension

    Abstract The topic of coronary Arteries in transposition of the great Arteries (TGA) is complex and confusing despite having been the subject of several recently published reports. One hundred thirty-three autopsy specimens of uncomplicated TGA were studied, with special attention to methodologic issues in anatomic description and classification. Uncomplicated TGA was defined as congenital anomaly involving origin of the aorta from the right ventricle and of the pulmonary artery from the left ventricle. Three types of transposition were recognized (“anterior aorta,” “side-by-side,” and “posterior aorta”) depending on the aortopulmonary relations, which were intrinsically defined by the relation of the valvular orifices of the great Arteries with respect to the atrioventricular orifices. The frequency of distribution of individual coronary patterns differs substantially in the first 2 types of TGA. As in normal hearts, coronary Arteries in TGA tend to originate from the facing sinuses (adjacent to the pulmonary valve); in TGA, however, variations in further distal anatomy are much more frequent. It is suggested that individual coronary patterns be described in terms of number of ostia, exact ostial location within or outside the aortic sinuses, and proximal course and distribution. The use of strict, simplified classifications of coronary patterns is discouraging because of the relevance of each individual anatomic parameter to clinical aims. Because of the aortopulmonary switch repair for TGA, this study emphasizes the surgical implications of the different coronary features.

  • Bilateral Fistulas from the Internal Mammary Arteries and the Bronchial Arteries to the Pulmonary Arteries
    Angiology, 1998
    Co-Authors: Ikuo Misumi, Kazuhiro Ueno, Yoshihiro Kimura, Youichi Hokamura, Hiroshige Yamabe, Tadamasa Yasunaga, Tatsuro Oguni, Chiaki Asao

    A 78-year-old man was admitted to hospital with heart failure and chronic bronchitis. A computed tomographic scan of the chest incidentally demonstrated bilateral abnormal vessels near the left atrium. Selective angiography showed that both internal mammary Arteries and bronchial Arteries communicated with the pulmonary Arteries bilaterally. The patient refused surgery and was discharged on medical therapy. This is the first reported case of bilateral fistulas between the internal mammary Arteries and bronchial Arteries and the pulmonary Arteries.

  • the movement of the brain stem and vessels around the brain stem in children with hydrocephalus and the arnold chiari deformity
    Developmental Medicine & Child Neurology, 2008
    Co-Authors: John L Emery, Richard K Levick

    SUMMARY Post-mortem angiography and dissection of the large vessels and tissues of the brain stem was carried out on 25 children with the Arnold Chiari deformity. An abnormal descent and looping of the basilar Arteries was seen, and a very considerable downward looping of the posterior cerebellar vessels occurred in association with the descent of the cerebellum into the spinal cord canal. Measurements at dissection indicated an average descent of the vertebral Arteries and pons of 10 mm. in children with thoracolumbar and 3 mm. with lumbosacral meningomyeloceles. There was a comparable descent of the base of the 4th ventricle of 30 mm. with thoracolumbar meningomyeloceles and 23 mm. with lumbosacral meningomyeloceles. RESUME Le deplacement du tronc cerebral et des vaisseaux autour du tronc cerebral chei les enfants atteints d'hydrocephalic et de la difformite d'Arnold Chiari Angiographic post-mortem et dissection des grands vaisseaux et des tissus du tronc cerebral ont ete pratiquees chez 25 enfants atteints de la difformite d'Arnold Chiari. Une descente et une courbure anormales ont eacute;te notees dans les arteres basilaires, et une tres importante courbure vers le bas des vaisseaux cerebelleux etait associee a la descente du cervelet dans le canal rachidien. Des mesures effectuees lors de la dissection ont indique une descente moyenne des arteres vertebrales et des apophyses de 10 mm. chez les enfants atteints de meningomyEloceles thoraco-lombaires, et de 3 mm. chez ceux atteints de myeloceles lombo-sacres. II y avait une descente comparable de la base du 4 ene ventricule de 30 mm. avec meningomyEloceles thoraco-lombaires et 23 mm. avec meningomyelocEles lombo-sacres. ZUSAMMENFASSUNG Bewegung des Gehirnstamms unci der Gefasse urn den Gehirnstamm bei Kindern mil Hydrocephalus und der Arnold Chiari Deformitat Post-mortem Angiographic und Dissektion der grossen Gefasse und Gewebe des Gehirnstamms wurden bei 25 mit der Arnold Chiari DeformitAt behafteten Kindern ausgefUhrt. Eine abnorme Senkung und Verschleifung der Basilar-Arterien wurde fest-gestellt, und eine ausserst bedeutsame Abwartsverschleifung der posterioren Gehirngefasse trat auf, in Verbindung mit dem Herabsinken des Cerebellums in den Ruckenmarkskanal. Messungen bei der Dissektion ergaben eine Durschnitts-Senkung der vertebralen Arterien und pons von 10 mm. bei Kindern mit thoraco-lumbarer und 3 mm. bei lumbo-sacraler Meningomyeloceles. Es gab eine vergleichbare Senkung des Bodens der 4. Gehirnkammer von 30 mm. bei thoraco-lumbarer Meningomyeloceles und 23 mm. bei lumbo-sacraler Meningomyeloceles. RESUMEN Movimienlos del tronco cerebral y de los vasos alrededor del tronco cerebral en ninos que padecen de hidrocefalia o de la defonnidad de Arnold Chiari Despues de la muerte, se hicieron una angiografia y una diseccion de los vasos grandes y de los tejidos del tronco cerebral en 25 ninos que habian padecido de la deformidad de Arnold Chiari. Se vieron un descenso y una curvatura anormales de los troncos basilares, ademas de un descenso y una curvatura muy considerables de los vasos cerebelosos posteriores, con un descenso del cerebro en el conducto de la medula espinal. Las medidas tomadas durante la diseccion revelaron un descenso medio de las arterias verticales y del puente de Varolio de 10 mms. en los ninos que tenian meningomielocclcs toracico-lumbares, y de 3 mms. en los ninos que tenian meningomieloceles Iumbar-sacras. Se hallo igualmente un descenso de la base del cuarto ventriculo de 30 mms. en los ninos que tenian meningomieloceles toracico-lumbares, y de 23 mms. en los ninos que tenian meningomieloceles Iumbar-sacras.

    Abstract Objective Congenital heart defects with major aortopulmonary collateral Arteries show marked variability in the size and distribution of native pulmonary Arteries. We sought to classify the size and distribution of native pulmonary Arteries and to determine their influence on surgical outcome. Methods Between 1989 and 2002, 164 patients underwent surgical intervention for congenital heart defects with major aortopulmonary collateral Arteries (median age, 10 months). Three patterns of native pulmonary Arteries were identified: intrapericardial native pulmonary Arteries present (group I); confluent intrapulmonary native pulmonary Arteries without intrapericardial native pulmonary Arteries (group II); and nonconfluent intrapulmonary native pulmonary Arteries (group III). Thirty-seven (23%) patients had single-stage and 76 (47%) patients had multistage complete repair. Thirty (18%) patients await septation, and 8 (5.0%) patients are not septatable. Follow-up is 98% complete (median follow-up, 5.8 years). Results In the 164 patients there were 15 (9.1%) early and 12 (7.3%) late deaths. Early mortality after complete repair was 4.4% (n = 5). Actuarial survival was 90% ± 3% and 85% ± 4% at 1 and 10 years, respectively. Actuarial freedom from surgical or catheter reintervention in septated patients was 77% ± 4% and 45% ± 8% at 1 and 10 years, respectively. On multivariate analysis, the morphology of the native pulmonary Arteries was the only factor that influenced actuarial survival after complete repair ( P = .04). Group III had the highest risk of death after septation ( P = .008). Group II fared better than group III after the initial operation ( P Conclusions Current classifications of congenital heart defects with major aortopulmonary collateral Arteries are based on the presence or absence of intrapericardial pulmonary Arteries. We have identified a subgroup without intrapericardial native pulmonary Arteries but with confluent intrapulmonary native pulmonary Arteries. This group has a better outcome than those with nonconfluent intrapulmonary native pulmonary Arteries.
