It may supervene with infection.

可能会并发感染。

About half of the patients supervene telangiectasis, and also associated with cerebral infarction and brain abscess.

半数病人可并发遗传性毛细血管扩张症，还可并发脑梗塞和脑脓肿。

Early diagnosis may be important because secondary local and systemic infection may supervene and, without timely and appropriate intervention, the disease often leads to sepsis and death.

早期诊断是极重要的，因为次发性局部或系统性之感染，若无即时且适当之治疗，会导致败血症和死亡。
