Thoracic duct embolization
Thoracic duct embolization (TDE) is a safe, efficacious treatment for chylothorax 1. Chylothoraces with a low drain output (<1L/day) are traditionally managed conservatively with dietary change, whilst high output (>1L/d) are managed with surgical thoracic duct (TD) ligation 2.
Thoracic duct em...

Percutaneous lung tumor ablation
Percutaneous lung tumor ablation techniques are an alternative to surgery or stereotactic body radiotherapy (SBRT) for the treatment of certain malignancies. They have specific indications and contraindications, but are mostly limited to small oligonodular and favourably located lesions.

Cauldwell classification
Cauldwell classification is a commonly used classification 4 in assessing bronchial artery branching patterns.
Classification
The bronchial artery branching pattern is classified into four types based on the number of intercostobronchial trunks (ICBT) - that give rise to the right bronchial ar...

Sniff test
The fluoroscopic sniff test, also known as diaphragm fluoroscopy, is a quick and easy real time fluoroscopic assessment of diaphragmatic motor function (excursion). It is used most often to confirm absence of muscular contraction of the diaphragm during inspiration in patients with phrenic nerve...

Peripherally inserted central catheter
Peripherally inserted central catheters (PICCs), often incorrectly tautologically termed PICC lines, are a type of central venous catheter predominantly used amongst oncology patients and those with chronic diseases (e.g. cystic fibrosis).
They offer the ability to have long-term central venous...

Preoperative pulmonary nodule localization
Preoperative pulmonary nodule localization is a CT-guided procedure where a marker is applied to a usually small lung lesion to assist in its surgical identification and resection. The widespread use of video-assisted thoracic surgery (VATS) and the advance in robotically assisted surgical inter...
Article
Thoracentesis
Thoracentesis, commonly known as a pleural tap or chest tap, is a procedure where excess pleural fluid is drained from the pleural space for diagnostic and/or therapeutic reasons. Ultrasound-guided thoracentesis performed by radiologists has been shown to have fewer complications than blind thor...

Tracheobronchial stent
A tracheobronchial stent is a device used to treat symptomatic airway compression.
This device is inserted under bronchoscopic guidance in patients with external compression from mediastinal-based malignancy, for example, lung or esophageal cancers. It may also be used in the treatment of trac...

Left paramediastinal catheter position (differential)
When a central venous catheter that is supposed to terminate in the superior vena cava or right atrium is abnormally located to the left of the mediastinum and below the level of the brachiocephalic vein, a limited differential of left paramediastinal catheter position should be considered 1:
l...
Article
Infusothorax
Infusothorax (plural: infusothoraces), also known as a chemothorax, is a complication of central venous catheter malposition where the catheter tip is located in the pleural space and the infusion of the fluid collects inadvertently in the pleural space in the form of a pleural effusion. Longer ...
Article
Heimlich valve
The Heimlich valve, also known as the flutter valve, is a unidirectional valve to ensure that gas/fluid drained from the pleural space cannot flow back in.
The Heimlich valve is cheap, easy to use, and does not require clamping unlike 'traditional' thoracostomy drainage tubes. Suction can stil...

Double lumen cannula for VV ECMO
The double lumen cannula enables veno-venous extracorporeal membrane oxygenation (VV ECMO) to patients with severe respiratory failure. It is often used as a bridge to lung transplant.
The cannulation is usually performed via the right jugular vein. This position allows the patients to stay aw...
