Ultrasound guided percutaneous dilatation tracheotomy (US-PDT) to prevent potentially life-threatening complications: A case report.

Introduction: Percutaneous dilatation tracheotomy (PDT) is a relatively recent technique that enables non surgeons to perform tracheotomies at bedside reducing operation rooms schedules. It is burdened by a moderate risk of postoperative bleeding.

Presentation Of Case: The patient was a 57 years old with a temporal intraparenchymal hematoma, submitted to percutaneous dilatation tracheotomy. Despite the favorable anatomical features, a pre-procedural US was performed, identifying a pulsating vessel with an arterial pattern, 2 cm above the hollow. The procedure was then considered at high risk, an operation room was required for the technique and an on-call surgeon was alerted. The procedure was ended safely and any bleeding was avoided because the technique was practiced with the best precautions.

Discussion: PDT strength is the possibility for non surgeons to perform tracheotomies in selected patients at bedside, reducing operation rooms congestion. Such technique though is a "blind" technique, and postoperative bleedings can occur and represent a feared complication. Conversely, the surgical tracheotomy permits a better control of hemorrhages, but needs the involvement of a surgeon and availability of an operation room. Performing a PDT guided by a neck ultrasound is useful to identify eventual aberrant vessel whose course could complicate the tracheotomy, it is part of PDT guidelines of some States.

Conclusion: US-PDT could help reducing procedure related complications selecting those high risk patients still in need of operating room and surgical assistance. US-PDT feasibility combined to its easy availability and low costs encourage its introduction into everyday practice.
