Abstract:
Ipsilateral pneumothorax is a common complication of pacemaker implantation due to transvenous lead placement. We report a case of bilateral pneumothorax after unilateral subclavian vein cannulation for pacemaker implantation. An 85-year-old woman underwent dual-chamber pacemaker implantation for symptomatic atrioventricular block. The transvenous leads were inserted through the left subclavian vein under fluoroscopy and contrast venography, and bilateral pneumothorax was noted the day after implantation, although echocardiography and computed tomography showed no pericardial effusion or lead extrusion. A chest tube was placed in the left chest cavity, which was removed one week later without complications.

Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
Oxygen Delivering System III: Tracheostomy and T-piece
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...
Tracheostomy Decannulation
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
