Patients and methods
Fourteen patients who underwent anatomic resection for primary lung cancer between February and September 2001 were included in this study. The 3D-CTPA images were obtained using an MDCT scanner (Somatom Plus 4-VZ; Siemens Medical System, Erlangen, Germany). Iodinated contrast medium was administered intravenously from the upper limb at a rate of 3.0 mL/s with a total dose of 100 mL by a mechanical injector. Images of the arterial phase were obtained by commencing the scanning when the injected
Scanning time
MDCT scanning required approximately 15 seconds per patient during a single respiratory pause, and the 3D images of pulmonary vessels were processed within 5 to 10 minutes after scanning.
Quality of images
PA branches were clearly identified at the subsegmental or more peripheral levels (Fig 1). Wearing special glasses offered more comprehensible 3D images. The reconstructed 3D-CTPA image of the PA could be rotated 360 degrees in any direction on the display screen. Although both PA and PV are visible in this 3D
Comment
Anatomic pulmonary resection such as lobectomy and segmentectomy is a common and basic procedure to treat various pulmonary tumors. Identification and appropriate treatment of the PA branches is a particularly important key to successful anatomic pulmonary resection although there are a multitude of anatomic variations in the PA branching pattern [2]. Because no one pattern for either the right or the left PA can be described as standard the thoracic surgeon must be mindful of the high degree

There are multiple reports describing the use of preoperative and intraoperative models in thoracic surgery to delineate pulmonary vascular and bronchial anatomy.33–37 Hagiwara and colleagues assessed 124 patients undergoing 3D-CT before pulmonary segmentectomy and found that pulmonary artery (PA) branches were accurately identified in 97.8% of cases, which included 15 cases of anomalous PA branches and 5 cases of anomalous pulmonary vein branches.
Comprehensive study of pulmonary hilam with its clinical correlation
2019, Annals of AnatomyCitation Excerpt :Thus pre-control of artery is essential in VATS lobectomy. If individual information about the exact number, location, or anatomic variation of pulmonary artery branches that have to be divided can be evaluated preoperatively in each case, the subsequent lung resection will be safer and more compatable (Watanabe et al., 2003). In present study, accessory arteries were present in 37.04% and 36.73% on left and right hilum respectively.
