Ligamentum flavum cysts may cause pain, radicular symptoms and signs. The diagnosis of ligamentum flavum cyst is done by radiologic studies, surgical intervention and histopathological examinations of the ligaments. In an 80-year female patient, in the inner aspect of the ligamentum flavum a cyst about ten mm's was found, compressing the S1 nerve root. In literature survey seventy-five similar cases were found. Careful exploration, incision and excision of the cyst and the ligament and its adherence to dura mater and facet joint are main problems.

Aim. We have conducted this study to seek and observe visual clues through immunohistochemical staining for differences in Et-1/2/3 expression and the free-low capacity measuring the blood flow through grafts, in the left internal mammary artery grafts prepared either with clipped or nonclipped techniques. Methods. A total of 40 consecutive patients with a diagnosis of coronary artery disease who would benefit from elective coronary artery bypass graft surgery were randomised into two groups consisting 20 patients each. Left internal mammary artery was harvested by a traditional clipped (control group) and a modified nonclipped (stu . . .dy group) technique in each of the groups. All harvested arterial segments were evaluated for luminal endothelial integrity through hematoxylin&eosin and immunohistochemical staining. Results. The free-low capacity of left internal mammary artery grafts were significantly higher in nonclipped arteries when compared with that of clipped ones (P=0.001). The arterial lumen of the nonclipped segments were visibly more dilated than the clipped ones. Nonclipped segments presented a lighter immunostaining for Et-1/2/3 when compared with the clipped ones ( Daha fazlası Daha az
