Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: 1. Malignant pulmonary tumor (suspected or confirmed) that necessitates resection lines other tan usual interlobar fissure 2. In addition to conventional criteria for VAL-MAP, there is anticipated advantage in using microcoil such as - Wedge resection is applied and the deep resection line is deeper than the outer 1/3 of the lung in CT, although the center of the tumor is in the outer 1/3, - the center of the tumor is within the outer 1/3 of the lung - high ldegree of pigmentation of the lung is anticipated

Exclusion criteria

Exclusion criteria: 1. Allergic to platinum 2. Allergic to indigo carmine 3. For some reason, intra-airway placement of the microcil is difficult 4. pregnant woman 5. younger than 20 or patients whose own willness cannot be confirmed 6. Bronchschopy and/or marking procedure is not feasible due to complications 7. Anatomy precludes successful resection defined in this study 8. Other reasons a participating surgeon/physician judges the patient is not appropriate candidate for the study
