Background:
Endovascular repair represents an option becoming progressively more integral to the treatment of thoracic aortic pathology. Effective use by practitioners of the most appropriate endovascular equipment is essential to the continued growth of this treatment modality. This article aims to provide an overview of the guidewires, catheters, and sheaths employed in the practice of thoracic endovascular aortic repair (TEVAR).
Methods:
We reviewed our current utilization of guidewires, catheters, and sheaths in TEVAR. Concurrently, we conducted a survey of the present medical literature with regard to the materials and methods used in this procedure by other cardiothoracic surgeons, vascular surgeons, and interventional radiologists.
Results:
Fundamental principals of the guidewires, catheters, and sheaths used in TEVAR are consistent across the spectrum of specialists performing this procedure. However, considerable variation exists in the specific products used by practitioners.
Conclusions:
The importance of proper training and experience with the endovascular equipment used in TEVAR cannot be understated. We believe the endovascular tools discussed in this article offer a proper selection for safe and effective performance of these procedures.

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...
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...
