数据说明

Lung infarct is a rare complication of lobectomy. Commonly, postoperative infarct is due to pulmonary torsion and rarely due inadvertent ligation of the pulmonary artery or vein of the residual lobe. Here is a rare case of infarct of the residual upper lobe following a right upper lobectomy, presenting with opacity in the right upper zone, reported as “gossypiboma” by a radiologist.
A 21-year-old man in otherwise good health underwent a right upper lobectomy for aspergilloma. The surgery was uneventful. On the third postoperative day, he developed a fever and dull aching pain in his right chest. Plain x-ray revealed an opacity in the right upper zone (Figure 1). Contrast enhanced computed tomography (CT) scan revealed intracavity mass with air bubbles and a long radio-opaque marker, reported by the radiologist as a retained surgical sponge (gossypiboma) (Figure 2).
Based on the CT report, an immediate surgical re-exploration was done, and there was no retained sponge but an infarct of the residual right upper lobe was noted (Figures 3 and 4). It was found that the cause of infarct was a misinterpretation of the fissure during staple separation of the upper from the middle lobe after ligation of the upper lobe artery during right upper lobectomy, leading to infarct of residual devascularized lobe. The infarcted part was excised by wedge resection, and the patient recovered well postoperatively.
Discussion
Lobar torsion predominantly occurs following right upper lobectomy when the oblique fissure is complete and the middle lobe has the potential to twist around its pedicle. Very rarely, infarct occurs without torsion of the lobes, and only one case has been reported in literature (1). When pulmonary arterial occlusion is associated with venous outflow interruption (as occurs in a right upper lobectomy), any remaining portion of the upper lobe becomes amenable to a wedge infarction (2). Intrathoracic gossypiboma is extremely rare, but reported and characteristic CT features include a spongiform appearance with gas bubbles. Differentials of intrathoracic gossypiboma include aspergilloma, bronchial carcinoma, bronchiectasis, hydatid cyst, and empyema. Interestingly,
