Acute aortic dissection is often a fatal condition with in-hospital mortality rates of 27%. The incidence of acute aortic dissection is low at around 3 cases per 100,000 person-years. There is a strong relationship between hypertension and aortic dissection. 72% of patients in the International Registry of Acute Aortic Dissection had a history of hypertension. The inciting event is an intimal tear extending into the media with resultant dissection of blood along the laminar planes of the media. Cisplatin, a commonly used platinum-based chemotherapy drug, is associated with the development of hypertension on long-term follow up studies. This knowledge should prompt clinicians to screen for the development of hypertension and to be aware of its potential complications in patients treated with cisplatin-containing chemotherapy. Despite the known vascular complications of chemotherapy, there is a paucity of data on the association of aortic dissection with active cancer or chemotherapy. We present an unusual case of an extensive, acute aortic dissection in a relatively young male patient receiving gemcitabine and cisplatin for advanced metastatic pancreatic adenocarcinoma.
急性主动脉夹层通常是一种致命疾病,院内死亡率为27%。急性主动脉夹层的发病率较低,约为每10万人年3例。高血压与主动脉夹层之间存在密切关系。国际急性主动脉夹层注册研究中72%的患者有高血压病史。诱发事件是内膜撕裂延伸至中膜,导致血液沿中膜的层状平面剥离。顺铂是一种常用的铂类化疗药物,长期随访研究表明其与高血压的发生有关。这一认识应促使临床医生对接受含顺铂化疗的患者筛查高血压的发生,并了解其潜在并发症。尽管已知化疗存在血管并发症,但关于主动脉夹层与活动性癌症或化疗之间关联的数据却很少。我们报告了一例不寻常的病例,一名相对年轻的男性患者因晚期转移性胰腺腺癌接受吉西他滨和顺铂治疗,发生了广泛的急性主动脉夹层。
