Hereditary protein C deficiency is a chromosomal genetic disease caused by mutations in the protein C gene,which can lead to venous thrombosis and is mostly related to mutations in exons 4-9 and intron 8.Fatal pulmonary embolism caused by mutations in the protein C gene is rare,and the treatment faces great challenges.This article reports a case of fatal pulmonary embolism caused by a frameshift mutation in exon 8 of the protein C gene and summarizes the treatment experience of combining extracorporeal membrane oxygenation (for respiratory and circulatory support) with interventional thrombectomy,providing a basis for the diagnosis and treatment of this disease.
遗传性蛋白C缺陷症是由蛋白C基因突变引起的一种染色体遗传病,可导致静脉血栓形成,多与外显子4~9和内含子8的突变有关。蛋白C基因突变引起的致死性肺栓塞罕见,治疗面临巨大挑战。本文报道1例由蛋白C基因8号外显子移码突变引起的致死性肺栓塞,采用体外膜氧合进行呼吸、循环支持,并成功实行介入取栓的救治经验,为该疾病的诊断及救治提供参考。.
