The medical records of 146 consecutive patients who underwent pneumonectomy for primary lung cancer between May 2001 and April 2006 at Samsung Medical Center in Seoul, South Korea, were reviewed retrospectively.
The patient subsequently underwent a right sleeve pneumonectomy; however, he tragically died secondary to intraoperative flash pulmonary edema in the left lung.
The lung is usually deflated during segmentectomy, lobectomy, and pneumonectomy, causing so-called surgical atelectasis or collapse (Figure 1, A).
(5) Bronchiectasis, pneumonia and other pulmonary complications like collapse and fibrosis are preventable to a large extent; surgical interventions like lobectomy and pneumonectomy may not be required at all (Bush et al., 2007.
Despite pneumonectomy and combination therapy with amphotericin B and caspofungin, there was failure to respond to therapy with extensive spread to the contralateral lung and pericardial involvement.
Prolonged aortic clamp time exceeding 30 to 45 minutes during aortic aneurysm surgery' and left-sided nephrectomy has been implicated, as has splenectomy, pneumonectomy and adrenalectomy.
Pneumonectomy of the patient was done on the basis of CT findings and CT-guided FNAC and after the histopathological processing of the specimen, it revealed similar bimodal population of cells, one of them being small darkly staining blue cells and the other being large light cells with moderate amount of cytoplasm tending to form rosettes at places.
The general approach was thoracotomy: 2 (4%) underwent pneumonectomy, 38 (81%) had lobectomies, and 7 (15%) had wedge resection (these were peripheral tumors with relapse in none of the cases).
To facilitate a pulmonary resection and improve access in the thoracic cavity, the lung is usually deflated during segmentectomy, lobectomy, and pneumonectomy. Especially during video-assisted thoracoscopic surgery procedures, visualization of the surgical field is seriously hampered by a ventilated lung.
[1] Following this, Bainbridge [2] (1901), Tyrell Gray [3] (1909), Berkowitz and Greene [4] (1950) described SA as an excellent alternative to general anesthesia (GA) in children including thoracic surgeries (lobectomy, pneumonectomy).
For the type of operative procedure, it is important to document the type/extent of resection (wedge, segmentectomy, lobectomy, bilobectomy, pneumonectomy, other) and for en bloc specimens, any attached anatomic structures received (eg, portion of rib, pericardium).
