Portable cardiopulmonary bypass: resuscitation from prolonged ice-water submersion and asystole.
Accidental hypothermia associated with near-drowning and cardiac arrest has a high mortality, especially in the adult. We report the resuscitation of a 31-year-old man who suffered extended ice-water submersion, severe hypothermia (23 degrees C), and prolonged (> or = 78 minutes) cardiac asystole. A modified portable cardiopulmonary bypass system and femoral-femoral cannulation in the Emergency Department permitted the rapid institution of core rewarming, oxygenation, and controlled reperfusion, with a successful outcome. Rapid initiation of cardiopulmonary bypass outside the operating room can be an initial treatment option in this unique clinical situation.

Subclavian balloon angioplasty in the management of the coronary-subclavian steal syndrome.
The syndrome of coronary-subclavian steal presenting with angina pectoris after coronary revascularization with the mammary arteries is not common. This disorder should be suspected in post LIMA patients with blood pressure differences between the arms and confirmed by angiography. PTA of the subclavian artery via the brachial approach, in appropriately selected patients, offers potential advantages over carotid subclavian bypass including an apparent lower complication rate with equally good results. Recurrences, which are apt to be more common after PTA versus carotid subclavian bypass, are easily managed with repeat dilatation. This course of management in our patient resulted in an excellent clinical outcome without complication. This report emphasizes the importance of considering subclavian stenosis in patients with prior LIMA bypass grafting, particularly when the ipsilateral arm blood pressure is reduced. In such cases, subclavian PTA offers a reasonable nonsurgical approach for correction.
