Preoperative Pulmonary Vasculature Mapping

Patients underwent CT pulmonary arteriography/venography (CTPA/V) using a 64-slice multi-detector CT (MDCT) unit (Aquilion-64, Toshiba Medical Systems, Tokyo, Japan) with injection of contrast medium (iodixanol, Visipaque 320, GE Healthcare, Cork, Ireland) after admission. Image data in DICOM format were imported into the Exoview system to complete the 3D reconstruction, with pulmonary bronchi, arteries, veins, and tumors marked out with different colors (Figure 2). Detailed parameters and procedures have been reported in our previous article (13 (link)). For each individual, careful preoperative planning was carried out by surgeons on the basis of the 3D reconstruction images to reduce the risk of unplanned injury of aberrant anatomical structures. Additionally, we briefly defined several variations of pulmonary vessels.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
