The Impact of Fissure-Adjacent Localization on Rupture Risk in Pulmonary Hydatid Disease.

Area of Science:

• Thoracic Surgery
• Parasitology
• Radiology

Background:

• Pulmonary hydatid cyst (PHC) rupture is a severe complication impacting surgical outcomes.
• Preoperative identification of rupture predictors is vital for risk stratification and surgical timing.

Purpose of the Study:

• To identify clinical, radiological, and laboratory predictors of PHC rupture.
• To specifically investigate the role of lung fissure relationships in PHC rupture.

Main Methods:

• Retrospective analysis of 37 patients undergoing surgery for PHC.
• Comparison of demographic, radiological, hematological, and operative data between ruptured and intact cyst groups.
• Multivariate logistic regression to determine independent predictors of rupture.

Main Results:

• Rupture occurred in 51.4% of patients.
• Higher preoperative C-reactive protein (CRP) and fissure connection were observed in the ruptured group (p < 0.05).
• Fissure relationship emerged as an independent predictor of rupture (OR: 5.150, p = 0.049).

Conclusions:

• Lung fissure involvement is a significant anatomical risk factor for PHC rupture.
• Preoperative imaging assessment of fissure-associated cysts is essential for surgical planning.
• Early identification of these cysts can improve patient outcomes and reduce surgical complications.
