Aneurysms of the extracranial internal carotid artery.

Aneurysm of the carotid artery is a rare pathology. According to the modern concepts, aneurysm of the artery is classified as a local enlargement of its diameter, namely by over than 50% as compared to the adjacent unchanged segment. In addition to the establishment as to whether aneurysm is present, the aims of examination consist in specification of the site, size, presence and extent of the interluminal thrombus. Duplex scanning is highly effective in so-called <> aneurysms, whereas in distal lesions its potential is insufficient. Today the greatest information content may be attained due to the application of spiral computed tomography (CT) by means of three-dimensional reconstruction or MRT but CT is more preferable. It is necessary to carefully visualize the intracranial bed.

Aromatic derivatives of mevalonic acid (2-phenyl-3-methyl-3-hydroxy pentanic and 2,3-diphenyl-3-hydroxy pentanic acids) decreased the yield of unesterified fatty acids from adipose tissue by about 28-36 percent after subcutaneous administration into rats within one or two weeks and under conditions of incubation of the adipose tissue in vitro. Distinct decrease in the yield of glycerol was cause by 2,3-diphenyl-3-hydroxy pentanic acid (1 with 10-minus 3 = 5 with 10-minus 3 M) under conditions of lipolysis stimulated by adrenaline. Antilipolytic effect of the preparation was more pronounced than that of well-known hypolipidemic drug clofibrate (p-chlorophenhydroxy isobutyrate).
