[Instent rupture of a saphenous vein graft during percutaneous intervention successfully treated with a covered stent]. / Rupture iatrogène intrastent d'un pontage aorto-coronaire veineux traitée avec succès par endoprothèse couverte.

Percutaneous coronary interventions of saphenous vein grafts are associated with an increased risk of periprocedural complications; among these, the rupture of the vein graft is probably the less common and the most dangerous; it is even more exceptional when it occurs on a stented portion of the graft. We report the case of a 75-year-old man who presented during a balloon angioplasty of intent restenosis of a saphenous vein graft a spectacular graft rupture at the level of the previously stented site and who was ultimately successfully treated with a covered stent.

[Bilateral tension pneumothorax after retrieval of transtracheal jet ventilation catheter]. / Pneumothorax bilatéral au retrait du cathéter de jet ventilation à haute fréquence.

We report a bilateral tension pneumothorax which occurred in a 36-year-old man after high-frequency jet ventilation (HFJV) for panendoscopy. The patient had been treated with radiotherapy and chemotherapy two years ago for an oropharyngeal adenocarcinoma, and by surgery for a recurrence. The incident occurred after a cough episode triggered by the withdrawal of the Ravussin transtracheal catheter. We are discussing the risk factors and the mechanisms of pneumothorax during HFJV with special emphasis on trapping and lung fibrosis.
