C1酯酶抑制因子系激肽系统的成分,具有重要的控制接触活化的作用。C1酯酶抑制因子缺陷患者,以复发性局限性、非化脓性、皮下水肿为主要表现,肿胀也可发生于上呼吸道,易引起窒息。对组织的轻微创伤如拔牙是引起血管性水肿的主要原因,其发病率较其它外科手术为高。作者对3例这类患者拔牙的预防和治疗作了回顾分析。 3例均为C1酯酶抑制因子缺陷患者,因拔牙而入院,以前有牙科治疗史,但未发生致命性的血管性水 C1 Esterase Inhibitors are components of the kinin system that have important roles in controlling contact activation. C1 esterase inhibitor deficiencies in patients with recurrent limitations, non-purulent, subcutaneous edema as the main performance, swelling can also occur in the upper respiratory tract, easily lead to asphyxia. Tissue minor trauma such as tooth extraction is the leading cause of angioedema, its incidence is higher than other surgeries. The authors retrospectively analyzed the prevention and treatment of tooth extraction in 3 patients. 3 cases were patients with C1 esterase inhibitor deficiency, admitted to hospital for tooth extraction, previously had a history of dental treatment, but did not happen fatal vascular water
