Peripheral Venous Hypertension Related to Arteriovenous Fistula for Hemodialysis-A Case Report

血液透析用動靜脈瘻管引發週邊靜脈高血壓-病例報告

摘要


靜脈高血壓在慢性血液透析的病患是一個值得重視的問題。原因可由前臂與手掌回流靜脈產生動脈化而造成,同時動靜脈管失去透析功能,上肢腫脹呈藍紫色或色素沈著的變化,有時會形成皮膚潰瘍,在嚴重的病例甚至會造成手指壞疽變化與神經痛。產生的原因可因靜脈系統產生動脈化而造成。病理變化與慢性靜脈循環不良形成的鬱血性皮膚炎類似,包括了真皮上部微血管壁增厚,內皮細胞較為膨大。早期診斷可預防嚴重的壞疽變化,因此對於皮膚科醫師來說相當的重要。

並列摘要


Venous hypertension is a significant problem for patients under chronic hemodialysis. Arterialization of the outflow venous system may induce this condition, and result in impairment of arteriovenous access function, disabling upper extremity edema, violaceous discoloration and hyperpigmentation, ulceration of the skin, and in advanced cases, gangrene formation of the fingers and neuralgia. Histologic features show thick-walled capillaries with plump endothelial cells in upper dermis, which are compatible with the pattern of stasis dermatitis by chronic venous insufficiency. Early awareness of these problems is crucial for dermatologists to prevent the extreme result of gangrene formation.
