Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
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...

Achieving precise thoracic endograft placement is difficult. Combining techniques like debranching, magnified imaging, and controlled deployment reliably improves accuracy for endovascular aneurysm repair.

Area of Science:

  • Vascular Surgery
  • Medical Imaging
  • Cardiovascular Interventions

Background:

  • Thoracic endograft placement presents challenges due to complex anatomy and hemodynamics.
  • Accurate positioning is crucial for successful endovascular aneurysm repair (EVAR).

Purpose of the Study:

  • To present a combined technique for precise thoracic endograft placement.
  • To evaluate the reliability and effectiveness of this approach.

Main Methods:

  • Utilizing debranching techniques to optimize the proximal landing zone.
  • Employing magnified imaging for clear visualization of supra-arch branches and landing area.
  • Using screen markers and deploying the endograft proximally to the target marker.
  • Implementing controlled deployment under hypotensive status or temporary cardiac asystole.
