In the post-operative course of the interventions of lung resection for primary tumor, complications of different nature and severity can arise, recognizing different pathogenetic mechanisms and differing according to the type of resection performed and to the time elapsed after surgery. The low diagnostic accuracy of chest radiography requires a thorough knowledge of the radiologist about all radiographic findings, both normal and pathological, which can be found in the immediate post-operative period (within 30 days after surgery). This article aims to describe the incidence, the clinical features and the radiological aspects of immediate complications following pulmonary resections, with specific reference to those in which the diagnostic imaging provides a fundamental contribution. important role in the surveillance of patients undergoing lung resection for primary tumor (3,4). This work aims to describe the incidence, clinical and radiological aspects of immediate complications that may arise after resection for primitive lung neoplasm, with specific reference to those in which imaging is able to provide an effective diagnostic contribution.
Description of immediate complicationsIn patients undergoing surgical treatment for non-small cell lung cancer (NSCLC) the first post-operative period can be divided into two phases, immediate and early. The two phases differ substantially from each other in relation to the different clinical conditions of the patients and to the different management. In fact, the different clinical conditions and management of patients affects the choice of the radiological technique. In the immediate post-operative course, study of the patient is carried out essentially in the ward and it is therefore limited-both in normal course or in the presence of complications-in obtaining radiographs, performed with portable equipment (only in selected cases can be employed chest sonography or CT); the radiologist plays a central role in the early diagnosis of post-operative complications (5). Patients who underwent greater anatomic resection (pneumonectomy, bilobectomy and lobectomy) are monitored radiologically initially with bedside chest radiographs, and then with the two standard chest radiographs acquired with the patient in the upright position. The timing provides a radiological control in first and second post-operative day, then at the removal of the former and second drainage (after lobar or bilobar resection) in fourth and fifth post-operative day, at discharge and then at varying intervals depending on the clinical evolution. In patients undergoing sublobar resection (segmental or atypical) monitoring is less frequent, with X-rays performed in first post-operative day, at removal of the single drainage (3-4 post-operative days), at discharge and later in accordance with the clinical evolution. Not infrequently, the radiographic finding is difficult to be interpreted and the distinction between normal evolution and the onset of post-surgical complications may be uncertain....
