Summary

Assessing surgical risk for lung resections involves evaluating pulmonary and cardiac function. Optimal assessment uses exercise testing and split-function studies to predict postoperative outcomes, guiding safe surgical decisions.

Area of Science:

  • Thoracic surgery
  • Pulmonary medicine
  • Cardiology

Background:

  • Pulmonary resections have reduced morbidity and mortality.
  • Assessing surgical risk is crucial for patient safety.
  • Pulmonary function tests and cardiac evaluations are standard risk assessment tools.

Purpose of the Study:

  • To review methods for assessing surgical risk in pulmonary resections.
  • To define parameters for safe surgical decisions.
  • To compare different risk assessment strategies.

Main Methods:

  • Review of pulmonary function tests (PFE1, TL,CO).
  • Cardiac risk assessment (ECG, echocardiography, nuclear studies).
  • Exercise testing (V'O2,max) and pulmonary split-function studies (ppo-parameters).

Main Results:

  • Normal pulmonary function allows pneumonectomy without further testing.
  • Maximal oxygen uptake (V'O2,max) <10 mL.kg(-1).min(-1) is prohibitive.
  • Predicted postoperative values (ppo) guide risk stratification for FEV1, TL,CO, and V'O2,max.

Conclusions:

  • Exercise testing and split-function studies refine surgical risk assessment.
  • Pulmonary function tests alone may overestimate functional loss.
  • Careful patient selection optimizes outcomes after lung resection.
