Summary
Thoracoscopic pulmonary wedge resection successfully treated peripheral pulmonary arteriovenous malformations in 6 patients. This minimally invasive approach offers a viable alternative when embolization is challenging or ineffective.
Area of Science:
- Cardiothoracic Surgery
- Pulmonary Medicine
- Vascular Surgery
Background:
- Pulmonary arteriovenous malformations (PAVMs) are abnormal connections between pulmonary arteries and veins.
- Peripheral PAVMs can be challenging to treat with conventional methods like embolization.
- Surgical intervention is sometimes necessary for complex or persistent PAVMs.
Purpose of the Study:
- To evaluate the efficacy and safety of thoracoscopic pulmonary wedge resection for peripheral PAVMs.
- To present surgical outcomes for a consecutive series of patients treated with this minimally invasive technique.
Main Methods:
- Six consecutive patients with peripheral PAVMs underwent thoracoscopic pulmonary wedge resection.
- A linear cutting stapler was used to resect the feeding artery, draining vein, and malformation.
- Operative details, complications, and postoperative outcomes were recorded.
Main Results:
- All 6 PAVMs were completely removed, confirmed by histology.
- Mean operative time was 50 minutes (range 30-95 minutes) with minimal bleeding.
- Postoperative hospital stay was one week, with no major surgery-related complications.
- One patient experienced a preoperative brain infarction due to embolization coil migration.
Conclusions:
- Thoracoscopic pulmonary wedge resection is a feasible and effective treatment for peripheral PAVMs.
- This minimally invasive technique provides a valuable alternative to embolization when it is difficult or unsuccessful.
- The procedure demonstrates good safety and efficacy for selected PAVM cases.
