This study was designed to investigate if it needs to do prophylaxis for pulmonary embolism in the patients treated with different kinds of dialysis or not, and if it is, to find a proper method for prophylaxis. Methods. Ten numbers of patients with central venous catheters (CVC group), 13 numbers of patients with arteriovenous fistula (AVF group) were enrolled in this study. Eleven patients treated with peritoneal dialysis (PD group) were utilized as a control group. Clinical and laboratory examinations to exclude pulmonary embolism were carried out in both AVF and PD groups at the onset and after three months. Same examinations were performed in CVC group at the onset and after 3 weeks (mean: 21 days). Examinations to exclude pulmonary embolism consist of medical history, clinical examinations, d-dimer measures, chest x-ray, respiratory function tests, blood gas analyses, ventilation-perfusion scintigraphies. Results. Neither clinical nor laboratory findings in any stages reflected any suspicion for pulmonary embolism. None of the patients in any groups was admitted with pulmonary embolism in any period of follow-up. There was not any statistically difference between the outcomes of all first examinations and of all second ones (P>0.005). Neither obvious nor subclinical pulmonary embolism was detected in any case. None of the patients had deep venous thrombosis in any stage of follow-up. Conclusion. Conventional techniques of haemodialysis do not lead to pulmonary embolism unless deep venous thrombosis due to any intervention occurs in the patients. Thus, prophylactic anticoagulant usage to prevent pulmonary embolism is not necessary in haemodialysis patients. To shorten the length of stay of central venous catheters is the most important factors for pulmonary embolism prophylaxis in haemodialysis patients.Öğe The mechanical or electrical induction of medullary angiogenesis: Will it improve sternal wound healing?(2004) Alat I.; Inan M.; Gurses I.; Kekilli E.; Germen B.; Harma A.; Eskin A.We induced angiogenesis in the tibial medulla and cortex of rabbits by electrical and mechanical stimulation, with the aim of future application to ischemic disease. Sixteen New Zealand rabbits were divided into 4 groups: in Group 1, a K wire was inserted into the medullary channel; in Group 2, a hole was drilled into the tibia; in Group 3, electrical stimulation was applied to the medullary channel; and in Group 4 (the control group), nothing was done. The interventions were applied during a 21-day period, after which all animals were evaluated scintigraphically and histopathologically. All 3 interventional groups were significantly superior to the control group in regard to medullary and cortical vascularity: the P values were 0.021 in all comparisons to control. However, the most fibrotic changes in the medulla occurred in the group that had been treated with electricity (P=0.008). Slight fibrotic changes occurred in the hole group (P=0.040), and none occurred in the K-wire group. In sum, all 3 interventions are capable of inducing medullary angiogenesis, but electricity is inferior in regard to fibrotic change. We believe that this present study can establish a baseline for further work that explores clinical applications to problematic ischemic conditions, including delayed sternal wound healing after cardiac surgery.Öğe The more Turkish without the racism [1] [Irkçilik olmaksizin daha çok Türkçe](2005) Alat I.[No abstract available]Öğe A new philosophy on stem cell trials in cardiovascular diseases: To collect pollen or to be a beekeeper [2](2005) Alat I.[No abstract available]Öğe Takayasu and giant cell (temporal) arteritis: The concealed realities(2004) Alat I.; Bahçeci F.; Taşkapan H.; Saraç K.[No abstract available]
