Takayasu arteritis is a chronic inflammatory arteriopathy of unknown etiology affecting large vessels, the aorta and its main branches. We experienced a case of Takayasu arteritis type III in a 9 years old girl. The diagnosis was made by physical examinations and digital subtration aortography (DSA) which showed occlusion of left subclavian artery and left renal artery and stenosis of abdominal aorta. Medical treatment and percutaneous transluminal angioplasty (PTA) were performed. A brief review of literatures was made.

OBJECTIVE: Although hemodialysis using heparin bound Hemophan (HBH-HD) has been reported to be a possible modality in patients at risk of bleeding, the efficiency and safety of HBH-HD is not certain. Therefore, we prospectively compared the safety and efficiency of HBH-HD with those of saline flushing HD (SF-HD) and HD using low dose heparin (LDH-HD) in 13 HD patients at risk of bleeding in a cross-over design. METHODS: The safety and efficiency were evaluated by measuring activated partial prothrombin time (aPTT) before and during HD, hemostasis time after needle removal, total blood compartment volume (TBCV) loss of dialyzer, urea clearance (K) and Kt/V. RESULTS: There was no difference in compression time needed to achieve hemostasis at puncture site after needle removal between HBH-HD, SF-HD and LDH-HD. During HBH-HD, there was a slight increase in aPTT at 15 min (50.6+/-4.5 sec), compared to predialysis levels (40.9+/-4.7 sec). In this cross- over study, aPTT during dialysis session was markedly higher in LDH-HD than those in HBH-HD or SF-HD (p<0.05). The loss of TBCV of the dialyzer was greater in SF-HD than HBH-HD or LDH-HD (17.4+/-1.9% vs. 12.4+/-1.4% vs. 10.1+/-1.8%). However, there was no difference in K (212.0+/-30.7 vs. 217.2+/-36.9 vs. 221.6+/- 29.5 mL/min) and Kt/V (1.22+/-0.12 vs. 1.24+/-0.16 vs. 1.26+/-0.18). CONCLUSION: We concluded that the safety and efficiency of HBH-HD are not different compared to SF-HD or LDH-HD and HBH-HD could an alternative hemodialysis method in patients at risk of bleeding.
