Presented in this study were three cases of lung cancer undergoing pulmonary venoplasty. In the 3 patients with central type of carcinoma of lung involving pulmonary vein, the main branch of right superior pulmonary vein and the distal end of the superior-lobe vein were occluded. The root part of the vein of right-middle lobe, plus part of vessel of of right superior vein was resected. The right superior vein was reconstructed by continuous 6-0 Prolene sutures. After the operation, the reconstructed was patent and the surgical margin was tumor-free. Postoperatively, clinical manifestations and plain chest films did not show any signs of venous blockade. The patients were discharged healed 3 weeks after the operation. The technical details of the surgery were presented, the improvements on the basis of traditional methods were discussed and its clinical application was evaluated. It is concluded that pulmonary venoplasty is a safe and feasible operation. Further improvement of the surgery will help conserve more lung tissue and benefit more patients because of expanded indications.

Airway management during carinal resection should provide adequate ventilation and oxygenation as well as a good surgical field, but without complications such as barotraumas or aspiration. One method of airway management is high frequency jet ventilation (HFJV) of one lung or both lungs. We describe a patient undergoing carinal resection, who was managed with HFJV of one lung, using a de-ballooned bronchial blocker of a Univent tube without cardiopulmonary compromise. HFJV of one lung using a bronchial blocker of a Univent tube is a simple and safe method which does not need additional catheters to perform HFJV and enables the position of the stiffer bronchial blocker more stable in airway when employed during carinal resection.

Bronchoplasty was extended to the segmental level and the effect of the multi-segmental surgery for the central non-small lung cancer was observed. The involved lobular bronchi and part of main bronchi were resected and single-layer continuous suture with 5-0 Prolene was used for suturing of the carina of the reconstructed segmental bronchi to form lobular bronchi. Then, single-layer continuous suture with 4-0 Prolene was employed to anastomose the "lobular bronchi" with main bronchi. Our results showed that the 15 bronchoplasties were successfully performed. The tumors were completely removed and postoperatively, the pulmonary functions of the patients were substantially improved. No broncho-pleural fistula and stomal stenosis took place in all the cases. The quality of life of the patients were obviously improved. It is concluded that multisegmental bronchoplasty can completely remove the tumor of central non-small-cell lung cancer and conserve more non-involved lung. The procedure is especially suitable for those patients with severely impaired lung functions and it expands the indications of surgical resection of lung cancer.

OBJECTIVETo explore the effects of ultrafiltration technique in preventing and relieving pulmonary injury in children undergoing open heart surgery and cardiopulmonary bypass (CPB).
METHODSThirty cases with congenital heart defects were divided into a control group and an experimental group. In the control group, conventional cardiopulmonary bypass was used without ultrafiltration; while in the experimental group, cardiopulmonary bypass with balanced ultrafiltration and modified ultrafiltration were used. Pulmonary static compliance (Cstat), airway resistance (Raw), alveolar-arterial oxygen difference (A-a DO2), hematocrit (HCT), serum albumin (Alb), interleukin-6 (IL-6), endothelia-1 (ET-1) and thromboxane (TXB2) were measured.
RESULTSThe pulmonary function was improved, HCT and serum albumin concentrations were increased, and some harmful medium-size solutes were decreased in the experimental groups compared with the control group.
CONCLUSIONSCombination of balanced ultrafiltration with modified ultrafiltration can effectively concentrate blood, exclude harmful inflammatory mediators, and attenuate lung edema and inflammatory responsive pulmonary injury.

5.Problem and strategy in surgical treatment of single ventricle.
Journal of Central South University(Medical Sciences) 2008;33(12):1071-1075
Single ventricle disease is a complex congenital heart anomaly with a high operative mortality. In the past few years, much progress had been made in surgical treatment of single ventricle. However, some problems in the diagnosis and treatment still remained. Based on the author's experience, the concept, morphology, and pathophysiology were reviewed and indications of various surgical techniques, problems during the operation and post-operation with their strategies were discussed in this article. Most single ventricular diseases are treated by Fontan series surgery; in which better results can be achieved through extra-cardiac conduct. Ventricular separation which is better than Fontan series surgery can be performed on those qualified. If the pulmonary vessels are maldeveloped, systematic to pulmonary shunt is preferred to promote the development of pulmonary vessels. When pulmonary hypertension occurs, Banding procedure is suggested to prevent pathologic changes of pulmonary vessels. The development of pulmonary vessels and total pulmonary resistance varies greatly from patients at different ages. Choosing appropriate patients is the key to obtain satisfactory outcome.The pulmonary vessel resistance and cardiac function status are the most important factors for successful operation.

6.Expression of pin1 mRNA in the circulation of non-small cell lung cancer patients and influence of sequence of vessel ligation.
Journal of Central South University(Medical Sciences) 2008;33(12):1132-1136
OBJECTIVE:
To detect the expression of peptidylprolyl cis/trans isomerase NIMA-interacting l (pin1 mRNA) in the circulation of non-small cell lung cancer (NSCLC) and to investigate the effect of ligating pulmonary vein first or ligating pulmonary artery first during operation on haematogenous dissemination of cancer cells.
METHODS:
Twenty-six consecutive patients with NSCLC who underwent surgical resection with curative intention were randomly assigned into pulmonary artery first-ligation group (PA group) and pulmonary vein first-ligation group (PV group). Blood samples were collected just before and 7 days after the operation. During the lobectomy, blood samples of the proximal part and distal part of the pulmonary vein when it was ligated were collected. Another 10 patients with benign lung disease served as control subjects undergoing surgical resection, and 10 healthy persons served as negative controls. All blood samples were subjected to real-time RT-PCR with pin1 mRNA as the marker.
RESULTS:
Compared with the benign lung disease and healthy persons, pin1 mRNA in NSCLC was overexpressed (1.45 to approximately 29.86 vs.0.83 to approximately 1.26 vs 1, P<0.05). pin1 mRNA in stage III NSCLC and lymph node positive were significantly higher than in stage I to approximately II and lymph node negative(18.48+/-1.64 vs.10.57+/-1.05, P<0.05;18.93+/-2.10 vs.10.02+/-1.23, P<0.05). Expression of pin1 mRNA in the distal part of the pulmonary vein was significantly higher than that of the proximal part (30.56+/-1.37 vs.20.31+/-1.48, P<0.05); the expression 7 days after the operation was significantly lower than that of preoperation (20.68+/-1.17 vs.29.43+/-2.62, P<0.05). There was no significant difference between the PA group and PV group (9.95+/-0.91 vs.14.71+/-1.64, P>0.05; 16.84+/-2.36 vs.13.36+/-1.78, P>0.05).
CONCLUSION
pin1 mRNA was overexpressed in the circulation of NSCLC. Ligation of pulmonary vein before the ligation of the pulmonary artery may decrease the expression of pin1 mRNA in the circulation, which can prevent the release of tumor cells into the bloodstream.

OBJECTIVETo review the surgical treatment of supracardiac type of total anomalous pulmonary venous connection (TAPVC).
METHODSTwenty-four patients with supracardiac total anomalous pulmonary venous connection underwent surgical correction from July 1995 to June 2004. There were 11 males, 13 females. The patients aged from 40 days to 35 years (mean 4.5 years). Twenty-three patients were under 6 years old. The weight was from 3.8 to 54.0 kg (mean 17.5 kg). Ten patients were through right atrial incision, 8 through double-atrium incision to anastomose the left atria and the common pulmonary veins. Two used large patches separating the portal of the common pulmonary veins and the enlarged atrial septal defects to the left atria. The left atrium and the common pulmonary veins were anastomosed in one case using a large patch separating the portal of the common pulmonary vein and the enlarged atrial septal defect to the left atrium. Three anastomosed the top of the left atria and the common pulmonary veins.
RESULTSOne patient died postoperatively of low cardiac output syndrome. One with cardiac tamponade after operation was cured by reoperation. Six with arrhythia were all cured. One with acute pulmonary edema was cured by reopen of the vertical vein and closed later. The postoperative follow-up period ranged from 3 months to 7 years (mean 2.5 years). One complicated severe supracardiac arrhythia 2 weeks later. One with late pulmonary occlusion was cured by reoperation. There was no long term complication of the others.
CONCLUSIONSThe operative methods of TAPVC depend on the cardiac deformation. Proper surgery timely treatment of the postoperative complications may achieve a satisfactory result. The method of only use patch in the right atrium should select proper repair material. Anastomosing the top of the left atrium and the common pulmonary vein is a good method. It is easy for exposure and operating, meanwhile it has low occurrence of arrhythmias and should be recommended.

BACKGROUNDThe Lecompte (REV) procedure is used to correct abnormal ventriculoarterial connections in patients with congenital heart diseases; it avoids the need for an extracardiac conduit for pulmonary outflow tract reconstruction. The present study aimed to investigate effectiveness and criteria of the REV procedure in children with abnormal ventriculoarterial connections.
METHODSThirty-eight children (mean age, (2.2 +/- 1.7) years; mean weight, (11.5 +/- 3.8) kg) with abnormal ventriculoarterial connections who had an REV procedure in our hospital from January 1998 to May 2006 were studied. Only 10 patients had the usual anteroposterior relationship of the two great arteries. The infundibular septum between the two semilunar valves was aggressively resected to enlarge it and construct a straighter left ventricular outflow tract and a wide tunnel between the ventricular septal defect (VSD) and the aorta. Eighteen cases had the original REV procedure; 20 had a modified REV procedure.
RESULTSAll patients are alive; none developed severe complications. The postoperative right ventricular (RV) to left ventricular (LV) pressure ratio was 0.20-0.45. Five patients had RV dysfunction; 2 patients had a pressure gradient in the RV ventricular outlet of 30.0-34.5 mmHg; 3 cases had a 37.5-47.3 mmHg pressure difference in the RPA. All patients had an RV pressure less than half the systemic pressure. These gradients' magnitudes in all patients were consistent with the post-operative RV to LV pressure ratio (P < 0.05). During the follow-up (mean, (4.2 +/- 0.6) years), 2 patients had an RPA pressure gradient of 24.0-29.3 mmHg which abated to less than 10 mmHg after two years.
CONCLUSIONSThe REV procedure provides satisfactory short- to medium-term results. It may be superior to the Rastelli procedure for treating ventriculoarterial connection abnormalities; it allows early, complete anatomic repair and reduces the need for late re-operation, since no extracardiac conduit is needed. Longer follow-up is needed to determine long-term outcomes.

9.Surgical treatment of anomalous origin of coronary artery from the pulmonary artery.
Chinese Medical Journal 2008;121(8):721-724
BACKGROUNDAnomalous origin of coronary artery from the pulmonary artery is a rare congenital cardiac malformation with a mortality rate of up to 90% within the first year of life without surgical intervention. Direct implantation of the anomalous coronary artery (ACA) into the aorta is successful in early life, but it may have increased surgical difficulty and risk with age. This retrospective study summarized our operative experience in direct implantation for treatment of this coronary anomaly in pediatric and adult patients.
METHODSFrom August 2000 to January 2003, 4 consecutive patients aged from 9 months to 41 years underwent dual coronary repair. Among them, two children and one infant with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) and one adult was anomalous origin of right coronary artery from the pulmonary artery (ARCAPA). Coronary arteries were directly implanted into the ascending aorta in 4 patients. In a boy with ALCAPA associated with moderate mitral insufficiency (MI), whose ACA arose remotely from the ascending aorta, we created a tube-shaped graft using part of the pulmonary arterial wall in continuity with the origin of the left coronary artery (LCA). Concomitant moderate MI was repaired in 2 patients, including this boy, after a dual-coronary repair.
RESULTSAll patients survived. There were no hospital or late deaths and no major complications as well. Echocardiography revealed that the left ventricular (LV) function including LV end-diastolic dimension (EDD) and ejection fraction (EF) was markedly improved at hospital discharge. At 3 - 6 years follow-up after surgery all patients were asymptomatic and currently in NYHA class I.
CONCLUSIONSThe best results are achieved with direct implantation of the ACA into the ascending aorta and simultaneous mitral valve repair if needed. Direct implantation is feasible in pediatric and adult patients with ALCAPA or ARCAPA including the coronary artery in a location remote from the ascending aorta. It is a good procedure to lengthen the ACA by creating a tube-shape graft using part of the pulmonary arterial wall in continuity with the origin of ACA.

OBJECTIVETo investigate the method of early surgical treatment of bronchopleural fistula after pneumonectomy.
METHODSTwelve patients (9 males and 3 females with a mean age of 58.6-/+5.7 years) with bronchopleural fistula after pneumonectomy received a reoperation within 72 h after a definite diagnosis. Empyema was found in none of the 12 cases. Fistula occurred within 4 to 17 days (8 days in average) after the operation. The fistula of the residual main bronchus was resected, and the thoracic cavity was asepticized by flushing.
RESULTSTen patients were discharged with complete healing. One patient was discharged following open drainage with daily change of the wound dress. One patient died due to multiple organ failure. The hospital stay of the patients ranged from 18 to 49 days (31 days in average) after the reoperation.
CONCLUSIONBronchopleural fistula after pneumonectomy, in case that empyema and multiple organ failure do not occur, can be healed by closing the fistula with the stapling device in early stage. Flushing the thoracic cavity is also necessary after the reoperation.
