Craniocervical necrotizing fasciitis of odontogenic origin with mediastinal extension.

We review an interesting case of craniocervical necrotizing fasciitis with thoracic extension in an immunocompetent 44-year-old man. The patient underwent aggressive medical and surgical management during a long hospitalization. Multiple surgical debridements, including transcervical mediastinal debridement, and eventually a thoracotomy for mediastinal abscess were required.

Prolonged cannulation of the left internal mammary artery (LIMA) for blood pressure monitoring in a child after cardiopulmonary bypass.

Cannulation of the radial artery percutaneously or by cut down is frequently used to monitor blood pressure in infants and children undergoing cardiopulmonary bypass. When radial artery cannulation is difficult because of previous cannulation attempts, and/or surgical cut downs, posterior tibial artery cannulation is sometimes undertaken. We describe a child in whom the left internal mammary artery (LIMA) was chosen for monitoring arterial blood pressure because of malfunction of the existing posterior tibial arterial pressure line after cardiopulmonary bypass.
