Summary
Double Y-stent placement successfully treated complex tracheobronchial stenosis in two patients with malignant disease. This innovative approach provided effective palliation for airway obstruction.
Area of Science:
- Pulmonology
- Interventional Bronchoscopy
- Oncology
Background:
- Silicone Y-stents are standard for main carinal stenosis.
- Tracheobronchial stenosis can be complex and not treatable with a single stent.
Observation:
- Two cases of malignant disease with complex tracheobronchial stenosis were analyzed.
- Stenosis involved the carina between the right upper lobe bronchus and bronchus intermedius, and the main carina.
Findings:
- Double Y-stent placement was performed as a single unit in both patients.
- The procedure successfully re-established airway patency and provided clinical palliation.
Implications:
- Double Y-stent placement offers a viable solution for complex tracheobronchial stenosis.
- This technique can improve quality of life for patients with malignant airway obstruction.

01:28Tracheostomy: 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...

01:16Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

01:23Oxygen Delivering System III: Tracheostomy and T-piece
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

01:22Trachea
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of the...

01:25Tracheostomy 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...

01:23Tracheostomy Suctioning II: Procedure
Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...
