Collateral circulation(側支循環)是當主要血管發生阻塞或功能障礙時,通過次要血管擴張和相鄰血管之間的既有吻合支建立的代償性血液循環系統。以下是詳細解釋:
形成機制
當動脈或靜脈因血栓、動脈粥樣硬化等病變導緻血流受阻時,周圍較細小的血管(如側支動脈或靜脈)會逐漸擴張,并通過預先存在的吻合支形成新的血流路徑,以維持組織供血或回流。這種代償機制可避免組織因缺血而壞死。
生理與臨床意義
相關病理與術語
側支循環的形成與動脈粥樣硬化、血管内皮細胞功能密切相關,其有效性受血流動力學和血管解剖結構影響。在影像學檢查中,評估側支循環狀态對制定治療方案(如血管介入手術)具有指導意義。
側支循環是機體應對血管阻塞的重要代償機制,其研究對心腦血管疾病、門靜脈高壓等疾病的診療具有重要價值。
