Chinese Journal of Thoracic and Cardiovascular Surgery 2001;17(3):162-164
Objective: To evaluate the effects of one lung ventilation on hemodynamics and blood gas during thoracoscopic surgery in piglets. Methods: Eight domestic pigs weighting (7.1±0.7) kg were included in this study. The anaesthesia was maintained with 1% isoflurance. After tracheotomy, an endotracheal tube was positioned in the left mainstem bronchus. Hemodynamic parameters as well as blood gas analyses were obtained using Swan-Ganz and arterial catheter. Results: During one lung ventilation, pulmonary artery pressure increased from (15.8±1.5) mm?Hg to (19.5±2.3) mm?Hg. Arterial oxygen saturation, blood gas analyses and other hemodynamic parameters remained unchanged. Conclusion: One lung ventilation was well tolerated in regard to hemodynamics and blood gas analyses in piglets.

Objective:To discuss the clinical and imaging features as well as the treatment and prognosis of primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma. Methods:We retrospectively analyzed the clinical, imaging, and follow-up data of 13 patients with pulmonary MALT lymphoma in the Chinese PLA General Hospital from April 2000 to July 2012. Results:Of the 13 patients with pulmonary MALT lymphoma, 8 were male and 5 were female (1.6:1 ratio). The age of onset varies from 21 years to 67 years, and the median age is 59 years. The major clinical manifestations include chest discomfort in 6 cases, cough in 2 cases, fever in 2 cases, and chest pain in 1 case. Two cases had no observable discomfort. One patient suffered from Sj?gren's syndrome. The chest CT of the patients showed pulmonary consolidation with air bronchogram in 3 cases, patchy shadows in 3 cases, mass shadow in 4 cases, and ground-glass opacities in 4 cases. In addition, 10 cases showed bilateral pulmonary multiple changes, 4 showed mediastinal lymph node enlargement, and 1 showed pleural effusion. Operation was performed on 6 patients, 3 of which were given postoperative adjuvant chemotherapy. Four patients underwent chemotherapy involving the CHOP or R-CHOP regimen, whereas three patients received symptomatic and supportive treatment only. One case was lost to follow-up. The follow-up period ranged from 1 year to 11 years. In one patient, the disease progressed four years after the diagnosis, and the patient died after 11 years. One patient died from the side effects of chemotherapy. The remaining 10 cases were still alive and did not show any progression of the disease. Conclusion:The clinical feature of pulmonary MALT lymphoma is not typical. Thus, imaging techniques cannot detect specific changes. Surgical resection is vital in the diagnosis and treatment of this disease because it can help provide a clear diagnosis, particularly to patients with limited lesions and from which specimens could not be obtained using conventional methods. Moreover, the prognosis of this treatment is generally good.

Purpose To evaluate the correlation between T2-FLAIR hyperintense vessel sign (HVS) and the stenotic degree of internal carotid artery (ICA) and assess the HVS changes after the carotid endarterectomy (CEA). Materials and Methods Fifty-one patients with CEA were retrospectively enrolled. The stenosis of the bilateral ICA were as:≥90%, and<90%. The distribution of HVS locations was classified as three regions:sylvian fissure, sulci of temporo-occipital lobe and other areas. The presence and the location of HVS were counted. The extrension of HVS on T2-FLAIR were graded as:I:the presence of HVS was<1/3 of the MCA territory, II:the presence of HVS was≥1/3 of the MCA territory.χ2-test was performed for correlation between HVS and ICA stenosis. The difference of HVS and stenosis of ICA and their effects on CEA was accessed. Results HVS was significantly higher in the ICA stenosis more than 90%group than in the less than 90% group (χ2=23.584, P<0.001). The frequencies of HVS were 12, 34 and 15 in sylvian fissure, sulci of temporo-occipital lobe and other area, respectively. The proportion of grade II HVS was higher in the ≥ 90% group than in the<90% group (χ2=8.395, P<0.05). After CEA, HVS on 29 affected hemispheres were showed to be disappeared (n=24) or remained (n=5) in the treated side. Conclusion The presence and the grade of HVS were correlated with the stenotic degree of ICA. In the patients with ICA stenosis, HVS was most frequently found in the sulci of temporal lobe and occipital lobe, and seldom found in sylvian fissure. HVS disappeared after CEA indicating that HVS can be considered as a marker for CEA treatment.

Objective To summarize the clinical characteristics, diagnosis and surgical management experiences of 51 cases of pulmonary fungal infections. Methods The clinical data of 51pulmonary fungal infection patients hospitalized in department of thoracic surgery of PLA General Hospital from 1981 to 2008 were retrospectively analyzed. Results The recruited cases included three cases of Candida albicans, 22 of Aspergillus, and 26 of Cryptococcus. The clinical symptoms included cough, hemoptysis, fever, chest tightness, chest pain and asthma. Twenty cases were identified through routine healthy examination. Of chest X-ray and computed tomograply scan, 29 cases presented with solid nodules in the lung, some of which had burrs and spikes; 13 presented with pulmonary cavity with even wall thickness and smooth inner wall including 7 with aspergillar glomera.Forty-eight cases underwent standard thoracotomy operations and 3 cases underwent thoracoscope or thoracoscopy-assisted minithoracotomy. Seventeen underwent pulmonary lobectomies, and 34 wedge resections. There was no operative mortality in the 51 patients. All diagnoses were confirmed by postoperative pathology. There was no relapse during 3- 10 years of follow-up. Conclusions Primary pulmonary fungal infections lack characteristic presentations in clinical manifestations and imaging examinations. Pathology is the evidence for definite diagnosis. Surgical intervention is an effective tool for diagnose and treatment of this disease.
