Objective:
A technique is presented for catheterization of an obstructed bronchus when use of a conventional vascular catheter has failed. In some cases, strictures become too stenotic or blunt for passage of a guidewire, making further intervention impossible. We attempted to negotiate a stricture opening using a transjugular intrahepatic portosystemic shunt (TIPS) dilator with a guidewire inside it.
Conclusion:
The catheterization technique with a TIPS dilator was successful in nine cases in which use of conventional catheters and guidewires had failed.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
