BACKGROUND Carotid artery stenting (CAS) has become an alternative treatment for patients presenting symptomatic carotid artery stenosis. The improvement in clinical outcomes with CAS has been associated with the development of embolic protection devices. The trial aim is to compare flow reversal versus filter protection during CAS through femoral access.(More)
Some patients with chronic cor pulmonale have hypoxemia only during normal daily activity. This can be corrected by portable oxygen. Whether or not the weight of the apparatus (4.2 kg) adds an additional metabolic demand of sufficient magnitude to cancel or outweigh the advantages of portable oxygen is the subject of this report in 6 patients with chronic(More)
We verified the utility of an oxygen economizer (Pendant Oxymizer) in assuring greater protection than nasal prongs against worsening of oxyhemoglobin resting desaturation (delta SaO2) induced by muscular exercise in 16 patients (ten with chronic obstructive pulmonary disease [COPD] and six with restrictive pulmonary disease). This worsening was quantified(More)
Peripheral neuropathy commonly occurs in patients with chronic obstructive lung disease (COPD). We report the presence of peripheral neuropathy in 19 of our 30 COPD patients (63.3%): 7 patients had clinical signs of a symmetric motor and sensory polyneuropathy, 12 patients had only subclinical evidence of peripheral nervous system involvement.(More)
We have evaluated the reliability of the transcutaneous (t.c.) method of measurement of arterial PO2 and PCO2 in adult man. In 33 simultaneous measurements of 9 normals and 12 patients with a wide range of hypoxemia, we found: t.c. PCO2 = 3.62 + 1.29 PaCO2 +/- 7.3 (r = 0.96) and t.c. PO2 = 11.14 + 0.86 PaO2 +/- 9.89 (r = 0.92). Recalculating t.c. PCO2 to 37(More)
