Abstract: Objective To evaluate the results of surgical treatment of tetralogy of Fallot in adults． Methods From July 2002 to August 2009，75 adult patients with tetralogy of Fallot received surgical treatment in Xijing Hospital, ForthMilitary Medical University．There were 35 males and 40 females, with age at l7 to 37 years (23.30±3.50 years), and eoperativehemoglobin at 143 to 231 g/L(172.00±31.00 g/L)．All these patients were diagnosed by.echocardiograph before operation. All the patients were received tetralogy of Fallot of corrective operation in the hypothermia cardiopulmonary bypass. A total of 46 patients had a transannular right ventricular outflow tract patch，and 29 patients had a non ansannular patch． Results Operation time was 157 to 276 min(221.32±41.34 min), cardiopulmonary bypass time was 68 to 163 min(91.71±28.35 min) and aorta intercepted time was 37 to 96 min（55.47±23.61 min）. There were 6 operative deaths with an operative mortality at 8.00％. The causes of death were low output syndrome(n=3)，acute renal failure(n=2)， and multiple organ failure(n=1)．Nine patients needed reoperation for postoperative bleeding(12.00％)．We followed up 69 patients from 3 to 56 months (26.31±7.40 months). There were 2 patients with trivial residual shunt. The cardiac function status were New York Heart Association(NYHA) Ⅰ to Ⅱ in the 69 patients．No late death occured． Conclusion The effectiveness of surgical treatment for adults with tetralogy of Fallot is satisfactory．
Abstract: Objective To summarize the experience of surgical treatment of tetralogy of Fallot (TOF) with anomalous coronary artery. Methods From March 1993 to April 2006, 22 patients with TOF and anomalous coronary artery underwent repair. The resection of hypertrophied parietal, septal band and the ventricular septal defect (VSD) repairs were performed by trans-right ventricular outflow tract (RVOT) approach in 5 cases, and by transatrial approach in 17 cases, which consisted of 7 cases required a transannular patch to enlarge a pulmonary annulus, construction of a double barrel outlet in 6 cases, by autologous pericardium conduit (3 cases), homograft (1 case) and reflected anterior wall of the main pulmonary artery in combination with bovine pericardium (2 cases). Results There was one operative death because of the anomalous coronary artery impairment. The accessory left anterior descending artery was severed because it was mistaken for the conal arteryin 1 case, which caused failure to wean from bypass, after the left internal mammary artery was anastomosed to the accessory left anterior descending artery, the cardiopulmonary bypass (CPB) was stopped successfully. Mean early gradient(ΔP) was 23.4mmHg and ΔP＞20mmHg in 9 cases. Eighteen cases were followed up, mean time was 13.2 months. Late ΔP＞20mmHg in 7 cases, and ΔP were less than 20mmHg in 11 cases. Conclusion The repair of TOF with anomalous coronary artery is more safe by using the transatrial approach. The surgical reconstruction of RVOT depends on the anatomic characteristic of anomalous coronary artery.
Abstract:Objective To summarize the experiences of single stage repair of interrupted aortic arch （IAA） associated with cardiac anomalies. Methods From Jan. 2000 to Dec. 2005, 48 patients admited in hospital and 35 patients were operated, the mean age at operation was 1.1 years. The associated anomalies included 23 cases of ventricular septal defect, 2 cases of transposition of great arteries, 3 cases of aortopulmonary window with aortic origin of right pulmonary artery, 2 cases of truncus arteriosus, 2 cases of double outlet right ventricle, 2 cases of stenotic fifth arch and 1 case of aberrant origin of right subclavian artery with mild hypoplastic decending aorta. Among them, 34 patients underwent single stage repair and 1 kid underwent palliative correction. Results There were 4 surgical deaths. The sequelae included one diaphragm paralysis and one 3rd degree of atrioventricular block. Only 5 kids recurred mild stenosis of aortic arch anastomosis and 2 death occurred during 3 months to 4 years of follow-up. Conclusion Though early surgical mortality for primary single stage repair is now relatively low, if appropriate interventions has been accomplished during perioperative period, but outcomes of IAA remain of concern, especially in patients with associated lesions.
Objective To investigate the effect of removing the implanted plate-rod system for scol iosis (PRSS) on maintaining scol iosis curve correction and preserving spinal mobil ity in patients with scol iosis. Methods From June 1998 to February 2002, 119 cases of scol iosis were treated with the implant of PRSS, which was removed 26-68 months later (average46.8 months). Complete follow-up data were obtained in 21 patients, including 6 males and 15 females aged 11-17 years old (average 13.8 years old). The disease course was 9-16 years (average 12.1 years). There were 2 cases of congenital scol iosis and 19 cases of idiopathic scol iosis, which included 5 cases of IA, 2 of IB, 1 of IIA, 2 of IIB, 2 of IIC, 2 of IIIA, 3 of IIIB, and 2 of IVA according to Lenke classification. There were 13 cases of thoracic scol iosis and 8 of thoracolumbar scol iosis. AP view and the lateral and anterior bending view of X-ray films before and at 3 to 6 months after removing PRSS were comparatively analyzed, the coronal and the sagittal Cobb angle were measured, and the height of vertebral body on the concave side and the convex side were measured, so as to know the effect of PRSS on the growth of the vertebral endplates. Results All the implants were removed successfully with an average operation time of 2.5 hours (range 2-4 hours) and a small amount of intraoperative blood loss. Twenty-one cases were followed up for 6-72 months (average 34.4 months). The coronal Cobb angle before and after the removal of PRSS was (20.25 ± 8.25)° and (23.63 ± 8.41)°, respectively, indicating there was no significant difference (P gt; 0.05); while the sagittal Cobb angle was (39.44 ± 12.38)° and (49.94 ± 10.42)°, respectively, indicating there was a significant difference (P lt; 0.05). The height of the top vertebral body on the concave side before and after the removal of PRSS was (1.78 ± 0.40) cm and (2.08 ± 0.35) cm, respectively, and there was a significant difference (P lt; 0.01); while the height on the convex side was (2.16 ± 0.47) cm and (2.18 ± 0.35) cm, respectively, indicating no significant difference was evident (P gt; 0.05). All the 21 patients had good prognosis and no major operative compl ication occurred. Conclusion PRSS is an effective instrumentation for the management of scol iosis. After the removal of the PRSS, the correction of scol iosis can be maintained, and the spinal mobil ity can be protected and restored.
Objective To explore the clinical effect of combining medial and lateral canthoplasty with blepharoptosis correction at onestage for congenital blepharophimosis syndrome. Methods From January 2002 to May 2006, 26 patients(52 sides) with congenital blepharophimosis syndrome were treated. There were 16 males and 10 females, aging from 3 to 35 years (mean 8.5 years). They were all bilateral blepharoptosis significantly. The palpebral muscle force was 03 mm; the transverse dimension and vertical dimension of the palpebral fissue were 13-22 mm and 2-4 mm; the intercanthal distance was 33-44 mm; the levator function was 1-3 mm. Results Twenty-six patients underwent medial canthoplasty and blepharoptosis correction, of them, 12 patients were also given lateral canthoplasty at one-stage. The postoperative transverse dimension and vertical dimension of the palpebral fissue were 6-8 mm and 24-32 mm, respectively. The intercanthal distance was 29-34 mm. The levator function was 46 mm. The supratarsal fold in the upper lid was natural. With a follow up of 3 months to 4 years，all patients were satisfied with their results. Conclusion One-stage surgical treatment of combining medial and lateral canthoplasty with blepharoptosis correction can achieve good result for blepharophimosis syndrome with a shortened treatment time.
Objective To explore the indication, advantage and disadvantage of modified or classical technique of intraoral sagittal split ramus osteotomy (SSRO) for correction of mandibular prognathism. Methods From January 1997 to January 2005, 95 patients suffering from mandibular prognathism or accompanied by other deformities were treated with modified or classical technique of intraoral SSRO. Of 95 cases, there were 34 males and 61 females, aging 15 to 44 years, including 53 cases of single mandibular prognathism, 28 cases accompanied with mandibular deviation, 11 cases accompanied with maxillaryretrognathism, 2 cases accompanied with glossacele and 1 case accompanied with malar protrution. X-ray cephalometry showed: sella-nasion-A point(SNA) 80-83°, sella-nasion-B point(SNB) 80-84°, A point-nasion-B point(ANB)-3-1°.Fortythree cases were corrected by modified SSRO and 52 cases by classical SSRO. Results The face appearance and dental articulation of all the patients were improved greatly. In patients by classical SSRO, disorder of local sensibility occurred in 9 cases, mandibular fracture during the cleavage ofthe ascending ramus in 1 case, significant bleeding in 1 case, postoperative infection in 1 case and postoperative relapse in 3 cases. In patients by modifiedSSRO, disorder of local sensibility occurred in 2 cases and postoperative relapse in 1 case; no mandibular fracture, significant bleeding, postoperative infection and other complications occurred. With a follow-up of 3 months to 7 years, X-ray cephalometry showed SNA 81-83°, SNB 78-81°and ANB 1-4°. 〖WTHZ〗Conclusion Modified SSRO is an ideal method of correcting mandibular prognathism, especially severer mandibularprognathism accompanied by mandible deviation deformity.
Objective To study the method of treating hemifacial atrophy withfree serratus muscle flap. Methods Three patients diagnosed as having serious hemifacial atroph was treated with free serratus muscle flap. The root of the flap was thoracodorsal artery and thoracodorsal vein, which was anastomosed with superficial temporal artery and vein, facial artery and vein, lingual artery and vein,and so on.During the operation, long thoracic nerve was dissected and anastomosed with facial nerve. The sizes of the flaps were 12 cm×8 cm16 cm×12 cm.Results All free-muscle flaps healed well after the transplant. The face and buccal area looked chubby and rounded. There were no obvious protuberance and discontentment on the buccal area. The shoulders of all patients moved well. The facial contourof the patients recovered well during the follow-up period (1.3 years). Conclusion The method has a good result, The long-term effect needs further study.
