[Unusual complication of venous thrombosis of the upper limb: pulmonary hypertension].

Although less frequent than that of the lower limbs, venous thrombosis of the upper limbs may cause pulmonary embolism. This embolism is usually moderate and facilitated by the delay or absence of anticoagulant treatment. We report the case of a young man who had multiple and recurrent embolism consecutive to thrombosis of the axillary and subclavian veins and who rapidly developed pulmonary arterial hypertension on previously healthy lungs.

[Electrophysiological characteristics of asymptomatic Wolff-Parkinson-White syndromes].

The management of the Wolff-Parkinson-White syndrome (WPW) is controversial especially when the patient is asymptomatic. The aim of this study was to evaluate the electrophysiological characteristics of such patients. Thirty two asymptomatic subjects with overt WPW on the surface ECG aged 14 to 68 years (average 36 +/- 15 years) underwent endocavitary or oesophageal electrophysiological study with the following protocol: programmed atrial stimulation using 1 or 2 extrastimuli over 3 cycles to evaluate the induction of paroxysmal junctional tachycardia and atrial fibrillation; atrial pacing at increasing frequencies to assess the shortest cycle conducted by the bundle of Kent.

[Dermoid cyst of the mediastinum fistulized into the bronchi (author's transl)].

The authors report a case of dermoid cyst of the mediastinum fistulized into the bronchi. This case was peculiar by virtue of its confusing clinical, radiological and biological characteristics which rendered the diagnosis difficult and in showing the value of bronchography in demonstrating the existence of the bronchocystic fistula. This excavated and fistulized tumor could be determined only after thoracotomy, confirming the primordial role of surgery in pathology of this type.
