Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...
Tracheostomy Care II: Procedure01:25

Tracheostomy Care II: Procedure

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask and...

Area of Science:

  • Neurosurgery
  • Radiation Oncology
  • Medical Imaging

Background:

  • Obstructive hydrocephalus can result from malignant pathology.
  • Minimally invasive techniques are sought for neurosurgical interventions.
  • Radiosurgery offers a precise, non-invasive treatment modality.

Purpose of the Study:

  • To describe a novel radiosurgical technique for third ventriculostomy.
  • To evaluate the feasibility and safety of this minimally invasive approach.
  • To address mild obstructive hydrocephalus secondary to malignant pathology.

Main Methods:

  • A radiosurgical third ventriculostomy was performed using a dedicated LINAC.
  • A 100 Gy dose was delivered to the floor of the third ventricle via multiple noncoplanar arcs.
  • The procedure targeted the midpoint between the mamillary bodies and infundibular recess.

Main Results:

  • A third ventriculostomy with a 2.63 mm diameter was confirmed by MRI at three months.
  • Ventricular size index (VSI) showed a 4% decrease one week post-irradiation.
  • No significant changes in metastatic lesions were observed, and no short-term morbidity was reported.

Conclusions:

  • This is the first report demonstrating LINAC-based radiosurgical third ventriculostomy.
  • The technique proved precise and safe in the short term.
  • This minimally invasive approach shows promise for managing obstructive hydrocephalus.
