    Notes: Abstract We investigated whether pre-existing subendothelial smooth muscle cell (SMC) accumulations in cholesterol-fed rabbits are transformed into foam cell plaques. Twenty-four rabbits received a standard diet supplemented with 2% cholesterol for 4 or 8 weeks. Six rabbits received a supplement of 0.3% cholesterol for 35 weeks. The aorta and other systemic and pulmonary vessels were studied by immunohistochemistry for smooth muscle cells SMC (α-SMC actin), macrophages (RAM11), cell replication (proliferating cell nuclear antigen) and endothelial cells (von Willebrand factor; vWF). Initially the foam cell plaques were composed exclusively of foam cells of macrophage origin (MFC). In more advanced lesions SMC and collagen fibres were also present, leading to a fibrous transformation of the plaque. Cell replication was mainly located in the MFC. The endothelial cells covering the plaques showed an increased immunoreactivity for vWF which was also deposited in the interstitium between the FC. Pre-existing subendothelial SMC did not transform into FC. The newly formed FC plaques remained clearly separated from the pre-existing subendothelial SMC. The development of the plaques can be attributed not only to monocyte recruitment but also to macrophage multiplication.

    Notes: Abstract Lymphocele is a most common surgical complication following renal transplantation. The indication for treatment is given when the lymphocele becomes hyptomatic. We succeeded in laparoscopically deroofing large lymphoceles in nine patients that were causing ureter compression in eight and ipsilateral leg edema in six cases. The postoperative course was uneventful, and the surgery-related hospitalization did not exceed 7 days. Severe adhesions and a thick lymphocele wall, which made preparation difficult, resulted in the transection of the transplant ureter in one case. Techniques and prerequisites that would help to avoid this type of complication are discussed. According to CT scan or sonography, there was no recurrence in any of the patients after a mean follow-up of 11 months. This technique seems to be superior to other methods of treatment because not only is a cure obtained with a single intervention, but there is also a low risk of infection and a short hospitalization.
