About this trial

A method of ICG counterstaining localization under target artery occlusion without cutting,It's a new method of localization of small pulmonary nodules.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

<1cm CTR≤0.75; <1.5cm CTR≤0.5; <2cm CTR≤0.25 Lung nodules

The tumor center is located in the peripheral 2/3 area of the lung field

Preoperative analysis and planning of watershed by 3D reconstruction

Clinically assessed as cT1aN0M0 stage IA1/cT1bN0M0 stage IA2 (eighth edition), clinically resectable

Disqualifiers

No surgical video, no postoperative gross specimen and related distance measurement records

The incision edge does not exceed the target nodule diameter from the nodule edge

The resection range exceeds 50% of the preoperative planning

Postoperative pathological staging non-pT1aN0M0 IA1 stage/pT1bN0M0 IA2 stage (eighth edition)

Trial design

Design model

Single group

Treatments tested in this trial

  • Wedge resection under watershed analysis method

    Procedure/Surgery

    * Compare the preoperative 3D reconstruction model, and use electrocautery to directionally separate and expose the target artery; * Auxiliary devices (unlimited) to block the target artery, but should not be severed; ③ Peripheral intravenous injection of ICG, electrocautery to mark the border of counter-staining; ④ Evaluate the actual incisal margin according to the preoperative planning, and use the cutting stapler to wedge resection of the pulmonary nodule
