[Left monoplegia revealing pulmonary arteriovenous fistual in an adolescent: occclusion with an Amplatzer occluder].

A 16 year old adolescent was admitted to hospital for investigation of a transient left monoplegia. The clinical, electric and radiological examinations were all normal. Echocardiography showed no abnormality of cardiac structures or function. Contrast echocardiography was performed and showed a right-to-left shunt suggesting a pulmonary arteriovenous fistula which was confirmed at angiography. The fistula was closed at catheterisation by a detachable balloon: in a second procedure, the balloon was deflated and contrast studies showed a recurrence of the right-to-left shunt. An Amplatzer 8/6 duct occluder was implanted with excellent results and no recurrence at 3 months.

[Teleradiographic analysis of velopharyngeal insufficiency in CATCH 22 association].

The CATCH 22 association (Cardiac defect, Abnormal facies, Thymic hypoplasia, Cleft palate, Hypocalcemia) combines certain signs common to various syndromes (Di-George syndrome, velocardiofacial syndrome, etc.) in combination with a 22q11 chromosomal microdeletion. Velopharyngeal insufficiency can be a complementary sign, or even a presenting sign of this chromosomal anomaly. After clinical examination of these patients, velopharyngeal insufficiency appeared to be due to a deep nasopharynx rather than to a short soft palate. We therefore reviewed 11 patients with teleradiography. We studied the length of the soft palate, the depth of the nasopharynx, the ratio of the depth of the nasopharynx over the length of the soft palate, and we compared our results with those observed in reference populations. The results demonstrate nasopharyngeal disproportion with a normal length of the soft palate and increased depth of the nasopharynx. This anatomical finding therefore encourages us to propose sphincteroplasty rather than velopharyngoplasty.

[Giant multifocal venous malformation with monomelic predominance].

INTRODUCTION: Venous malformations are usually easy to recognise. We describe one case in which the clinical aspect was suggestive of Maffucci's syndrome. OBSERVATION: A 44-year-old male, had numerous angiomatous nodules which could be emptied by pressure since infancy. The progressive increase in volume of these lesions on the arms and forearms led to enormous deformation and major disability. The thoracic area and the right foot were also affected to a lesser degree. Two endobuccal lesions were also found on the clinical examination The cutaneous lesions were tender and occasionally hyperhidrosis was present. The presence of phleboliths on Xray and the presence of venous and capillary cavities with numerous thrombi confirmed the diagnosis of venous malformation. Following the failure of the Ethibloc(R) embolization, eight excisions were made in a two-year-period with a good functional result. Elastic strapping was then applied. DISCUSSION: The diagnosis of venous malformation was based on clinical, radiological and histological findings. The absence of chondroma excluded the diagnosis of Maffucci's syndrome. Spindle cell hemangioendothelioma, "blue rubber bleb nevus" and glomangiomatosis were confirmed by the histological findings. The absence of port-wine stain or bone hypertrophy and the presence of multiple nodules excluded Klippel-Trenaunay syndrome. The presence of multifocal involvement with oral lesions, the severity of the deformation and the relative success of the surgical procedure make this case unusual.

Rupture of a sinus of Valsalva aneurysm in a neonate.

A neonate with severe congestive heart failure due to rupture of the right sinus of Valsalva into the right ventricle is described. The initial diagnosis was made with colour Doppler echocardiography and confirmed by aortography. Patch closure of the sinus of Valsalva defect was performed successfully on the 3rd day of life.

[Median- and long-term results of Mustard and Senning operations in isolated transposition of great vessels].

This study concerns 89 cases of isolated transposition with early surgical repair by auricular transposition of the venous returns. Fairly good results were obtained with an operative mortality rate less than 10%, few postoperative complications, and long-term follow-up without significant worsening of the functional capacities of these patients. From this study, the authors state precisely the present indications for treatment of isolated transposition.
