Neofissure after right upper lobectomy: radiographic evaluation.

Summary

A neofissure forms after right upper lung lobectomy, separating the middle and lower lobes. Computed tomography (CT) scans effectively visualize this neofissure in most patients, aiding anatomical understanding.

Area of Science:

  • Thoracic surgery
  • Radiology
  • Anatomy

Background:

  • Right upper lobectomy is a common thoracic surgical procedure.
  • Post-surgical anatomical changes require clear visualization for accurate interpretation.
  • The neofissure is a newly formed anatomical boundary after right upper lobectomy.

Purpose of the Study:

  • To evaluate the visibility of the neofissure on chest radiographs and CT scans after right upper lobectomy.
  • To describe the anatomical orientation and characteristics of the neofissure.

Main Methods:

  • Retrospective analysis of chest radiographs and CT scans from 25 patients who underwent right upper lobectomy.
  • Assessment of neofissure identifiability and orientation on imaging.
  • Correlation of neofissure location with adjacent lung lobes.

Main Results:

  • The neofissure was identifiable on CT scans in 96% of patients, compared to 28% on radiographs.
  • When fully visualized, the neofissure was predominantly coronal (60%), anteriorly and superiorly displaced.
  • Variations in orientation included partial coronal-sagittal (35%) and predominantly sagittal (5%) planes.

Conclusions:

  • CT imaging is highly effective for visualizing the post-lobectomy neofissure.
  • The neofissure's orientation varies, typically maintaining a predominantly coronal plane.
  • Understanding the neofissure's anatomy is crucial for interpreting post-surgical imaging of the right lung.
