Transcutaneous angioplasty of vertebral artery atheromatous ostial stricture.

The authors report experience of intravascular angioplasty of atheromatous ostial strictures of the vertebral artery in 24 patients. After reviewing the technique, they outline the indications provided through Doppler velocimetric data. The results seem to be encouraging as symptoms disappeared completely in 21 patients.

Coexpression of two thermosensitive defects in a Chinese hamster cell line. Manifestation of a G1 block associated with a mitosis defect.

Asynchronous cultures of ts12, an anchorage-dependent derivative of the thermosensitive Chinese hamster cell line ts111, show a rapid drop in [3H]thymidine incorporation with accumulation of the cells in the G1 and in the G2 phases of the cycle, when shifted from 34.5 to 39.4 degrees C. Shift-up experiments carried out after either isoleucine deprivation or synchronization at 39.4 degrees C, locate the execution point of a ts function in late G1 (2.5-3 h before S). However, stimulation of proliferation of a high density-arrested population allows a fraction of the cells to enter S. In addition to the G1 ts defect, ts12 expresses a slight cytokinesis defect at 39.4 degrees C (8-15% binucleate cells). The results suggest that altered processes are taking place at a post-metaphasic stage during the first hours after the shift-up. When populations are synchronized by a thymidine block and released at 39.4 degrees C, multinucleate cells in addition to binucleate cells are observed. Part of these multinucleate cells result from abnormal karyokinesis without inhibition of cytokinesis. Evidence is presented suggesting that excess thymidine allows the re-expression of the multinucleation phenotype of ts111.

[Endoluminal angioplasty for atheromatous stenoses of supra-aortic trunks. The brachiocephalic arterial trunk, subclavian arteries].

The authors are reporting their experience about percutaneous transluminal angioplasty in atheromatous stenosis of proximal supra-aortic arteries. In this series of 12 patients, with an 6 months follow-up, vertigo was the main clinical symptom (6 cases), and it must be pointed out that 5 of these 6 patients also underwent a proximal angioplasty of one or the two of their vertebral arteries at the same time. Two subclavian steal syndromes, one arterial insufficiency of an upper limb, one transient cerebral ischaemia, and two asymptomatic cases were also treated by the same procedure. For diagnosis as well as for follow-up, the authors are emphasizing the value of hemodynamic results of Doppler recording. As for the technics itself, it mainly derives from the PTA of the lower limbs arteries. The results in this series appear to be good from an hemodynamic point of view, with neither morbidity, nor mortality.

[Chemical sympathectomy in the treatment of arteriopathies of the lower limbs].

Phenol injected transcutaneously into the lumbar sympathetic chain appears to be effective in ischemic arterial disease of the lower limbs. Among the other procedures, such as angioplasty, belonging to the field of therapeutic radiology, this technique seems to have it's specific indications. A preliminary study in fifty patients is reported.
