肺動静脈奇形に対する塞栓術のコンプレックスケース

抄録

Pulmonary arteriovenous malformations (PAVMs) are abnormal communications between the pulmonary arteries and veins without any intervening capillary beds, and cause hypoxemia, cyanosis, dyspnea, and neurologic complications consisting of trans ischemic attack, stroke, and brain abscess. Thus, treatment for PAVMs is justified even for asymptomatic ones, and recently transcatheter embolization has become a common procedure. Meanwhile, complications can occur during embolization such as chest pain, cerebral infarction, and migration of the embolic material. Furthermore, persistence after the successful embolization is also an important issue. However, there are some other pitfalls. Herein, we introduce two complex cases of embolization for PAVM.
