MRI of the gastroepiploic artery used as a bypass graft.

The right gastroepiploic artery (RGEA) is recognized for its long-term patency as a coronary artery bypass graft, a property shared with the internal thoracic artery. The usefulness of MRI for noninvasive visualization and evaluation of the RGEA graft was assessed using a spine coil as the surface coil in 14 patients with graft patency verified by postoperative angiography. The graft was visualized by spin-echo imaging as a signal-void surrounded by lipomatous tissue with high-signal intensity in all 14 cases. Cine MRI was also performed in 13 of the 14 patients; in each case the graft was confirmed to contain blood flow of high-signal intensity.

Respiratory function and acid-base status in accidental hypothermia assessed by arterial blood gas analysis.

To study the respiratory function and acid-base status in hypothermia, we retrospectively reviewed data of arterial blood gas analysis obtained from 63 patients with accidental hypothermia on admission. Twenty-nine showed acidemia and 16 showed alkalemia. The following results were obtained from 57 patients in whom blood gas analysis was performed in room air. PaCO2 was 46 mmHg or more in 2 and 34 mmHg or less in 46. Most of the patients exhibiting acidemia had metabolic acidosis except 2 with severe pneumonia or subdural hematoma. PaCO2 was low even in the patients with alkalemia. PaO2 was 60 mmHg or less in 8, of whom 7 had pneumonia, and 70 mmHg or more in most of the patients without pneumonia. We found that patients with accidental hypothermia generally showed a respiratory function proportionate to their decreased metabolism or hyperventilation, and most of the patients with acidemia exhibited metabolic acidosis.
