Answer

Answer

An untreated PTA can lead to numerous complications, including the following:

  • Erosion of the carotid artery

  • The development of sepsis

  • The development of other localized serious bacterial infections, including mediastinitis and deep neck space infections, which arise from tracking of the infection from the tonsillar fossas to the deep fascial planes of the neck with extension into the chest
