[Angiographic identification of spinal cord arteries before bronchial artery embolization].

Ischemic spinal cord injury is the major risk of bronchial artery embolization. The spinal artery may be overlooked on initial intercostobronchial trunk arteriography, as a result of reverse flow within the intercostal branch. Its identification, conversely, is easier on postembolization angiography.

[Management of severe amiodarone-induced pneumopathy using inhaled nitric oxide].

Treatment of amiodarone-induced pulmonary toxicity generally consists in simply discontinuing the drug with subsequent improvement in clinical condition and radiologic abnormalities. Corticosteroid therapy, when used, may accelerate recovery. Early diagnosis is however necessary and mandates the immediate cessation of the drug otherwise diffuse interstitial and alveolar damage can develop and lead to acute respiratory distress syndrome with a high rate mortality.

[Failures and complications of bronchial artery embolization].

Bronchial artery embolization (BAE) is well accepted and widely used for management of massive and recurrent hemoptysis. Recurrent hemoptysis occurs in 20% of cases. It may be due to partial embolization, recruitment of other systemic collaterals, recanalization of an embolized artery, or progression of primary disease.

[Percutaneous vertebral biopsy].

CT-guided vertebral biopsy is a simple, non dangerous, and usually an effective method for the actiological diagnosis and the treatment of vertebral lesions. The authors detail the biopsy technique, the needles and the route used according to the anatomical distribution and the osteosclerotic or osteolytic aspect of the vertebral lesion. In 60% of ordinary infectious spondylodiscitis the biopsy is positive.

[Renal artery occlusion: percutaneous revascularization].

The value of percutaneous revascularization of acute or chronic occluded renal arteries is demonstrated in 9 cases. Recanalization and dilatation was technically successful in 6 patients. The authors stress the importance of anatomo-radiologic criterion for successful recanalization.
