RESUMO
Objective To investigate the clinicopathological characteristics and postoperative prognosis analysis of intra-thoracic localized Castleman disease (LCD).Methods The clinical data of 9 patients with intra-thoracic LCD who accepted surgical treatment were retrospectively analyzed.There were 5 males and 4 females,with age of (32.8 ± 10.9) years.Two patients complained of chest pain,1 patient suffered from paraneoplastic pemphigus,and the rest were diagnosed by physical examination.Four cases were diagnosed with LCD by preoperative CT examination.Results All patients underwent surgical resection.Four patients were performed open surgery and 5 patients had video assisted thoracic surgery.All patients accepted radical surgery.But 2 of these patients had postoperative complications.One patient was the injury of phrenic nerve and another was pericardial effusion.Patho-histological showed hyaline vascular type of Catleman disease in all patients.All patients survived without recurrence during the follow-up for 2-53 months.Conclusions Intra-thoracic is rare and liable to misdiagnosed.For increasing the preoperative diagnosis rate of LCD,the combined application of imaging tests is important,and clinicians and radiologists should also enhance the awareness of this disease.Complete surgical resection of the tumor is the best therapeutic alternative for intra-thoracic LCD.
RESUMO
Objective To evaluate the effect of video- assisted thoracoscopic pulmonary segmentectomy in patients with isolated pulmonary arteriovenous fistula (PAVF). Methods A retrospective analysis was performed on 10 patients with PAVF in the department of thoracic surgery of the first affiliated hospital of Nanjing Medical University between January 2010 and December 2016. Computed tomography angiography (CTA) and three-dimensional reconstruction were performed before operation, and all patients accepted video-assisted thoracoscopic pulmonary segmentectomy. Results The diagnosis of PAVF was identified by CTA, with maximum diameter of tumor of 3.0- 5.0 cm. No perioperative mortality or postoperative complications were observed including bleeding, hemoptysis, serious air leakage, and bronchopleural fistula. The lesions were completely removed in all 10 patients, and no patients converted to open surgery intraoperatively. Blood gas analysis showed that oxygen partial pressure before operation, in the first day after operation and the third month after operation was (62.5 ± 6.7), (70.2 ± 4.8) and (75.4 ± 4.8) mmHg (1 mmHg = 0.133kPa) respectively; which was significantly increased successively (P<0.05). After a follow-up time of 3-30 months, no recurrences were observed. Conclusions Video- assisted thoracoscopic pulmonary segmentectomy guided by preoperative CTA and three-dimensional reconstruction is a very effective method for the treatment of isolated PAVF.
