ObjectiveTo summarize experience of surgical treatment of ascending aortic aneurysm and analyse related problems.MethodsOne hundred and fourteen (containing 62 cases had aortic dissection) consecutive cases underwent replacement of diseased ascending aorta alone (9 cases) or Bentall operation.ResultsThere were seven operative death (6.14%). The cardiac function, in six of them, was in class Ⅳ(NYHA) preoperatively. Follow up was completed in 107 patients, with a duration of 40±30 months. Eight patients succumbed due to intracranial hemorrhage (3 cases), rupture of abdominal aortic lesion (3 cases), cardiac failure after coronary artery bypass grafting (1 case), and sudden death of unknown cause (1 case),respectively. All 99 long term survivors (86.8%) were in NYHA class Ⅰor Ⅱ.ConclusionThe results indicate that Bentall operation for treating ascending aortic aneurysms and aortic insufficiency, or aortic replacement alone for treating ascending aortic aneurysm gives good functional recovery and an active life for the vast majority of survivors.
Objective To summarize the experience of open heart operation on neonates with critical and complex congenital heart diseases and evaluate the methods of perioperative management. Methods From May 2001 to January 2003, 12 patients of neonates with congenital heart diseases underwent emergency operation. Their operating ages ranged from 6 to 30 days, the body weights were 2.8 to 4.5 kg. Their diagnoses included D-transposition of the great arteries in 4 cases, ventricular septal defect with atrial septal defect in 5 cases, complete atrioventricular septal defect, obstructed supracardiac total anomalous pulmonary venous drainage and cardiac rhabdomyomas in 1 case respectively. 12 cases were operated under moderate or deep hypothermic cardiopulmonary bypass. Results All cases were observed in ICU for 2-11 days and discharged 7-19 days after operation. The postoperative complications included low cardiac output, mediastinal infection, respiratory distress syndrome, systemic capillary leak syndrome and acute renal failure. All cases were cured and the follow-up (from 6 months to 2 years) showed satisfactory outcome. Conclusion A particular cardiopulmonary bypass and proper perioperative management is very important to ensure the successful outcome. Peritoneal dialysis is an effective and safe method for treating acute renal failure after cardiac operation in neonates.
Objective To summarize the visual outcome of patients with severe ocular trauma treated with vitreous surgery. Methods Clinical data of 188(191 eyes) with severe ocular trauma treated with vitreous surgery in a period from November 1996 to April 1998 were analysed retrospectively. Results The study included penetrating injury in 56 eyes, foreign bodies in the posterior segment in 70 eyes, blunt injury in 41 eyes , and globe rupture in 24 eyes. Main complications included endophthalmitis in 35 eyes, choroidal bleeding in 20 eyes, retinal detachment in 60 eyes, and vitreous hemorrhage in 97 eyes. Post-opera-tively, out of 188 eyes, except for 3 of patients too young to examine, visual acuity improved in 133(70.7%), including 85(45.2%) with visal acuity 0.02-1.0, 46(24.5%) remained unchanged; and 9(4.8%) had worse vision. Among 34 with no-light-perception, 12 had light-perception or over. Conclusion A majority of severe trauma eyes can be salvaged with considerable visual recovery after adequate and timely vitreous surgery. (Chin J Ocul Fundus Dis,1999,15:4-6)
OBJECTIVE: To evaluate clinical result of reconstructed thumb and finger with a free hallux nail flap(HNF) and frozen-phalanx-joint-tendon-sheath composite tissue allograft in 270 cases. METHODS: The patients were followed up with reexamination in the ambulant clinic, communication, X-ray photography, lab-examination, isotope 99mTc MDP and reoperation. The data were analyzed by statistics or proved by clinical observation, which were followed up for five years in average (ranging from five months to sixteen years). RESULTS: Enveloping the allogeneic finger composite tissue with self-HNF and pieces of phalanx of great toe, it could reconstruct a thumb or finger with good contour and nutrition. The excellent rate of opposition function of the reconstructed thumbs was 71.91%. The sense of the fingers recovered after 3 months to 8 months of operation. Two-point discrimination was 3 mm to 15 mm. The junction between implanted allo-phalanges and auto-phalanges could be hastened by implanted with vascularized autogenous phalanx pieces in the HNF. The isotope 99mTc MDP was used to take X-ray photography in 24 cases for four months to 9 years and seven months, which showed that the blood vessels grew into the allo-phalanges. However, the Charcot’s arthropathy of allogeneic joints and bony absorption still could be seen in some cases. That might be concerned with chronic abrasion of joint or chronic rejection of host to graft. CONCLUSION: The operation is fit for repairing the defect of thumb or finger in any degree. The implanted vascularized self-phalanx pieces can promote bone union, but it can not prevent the allogeneic joints from arthropathy or bone absorption
Objective To analyze the causes and the reoperation therapies after salvage limb surgery with prosthesis for bone tumors. Methods The retrospective analysis was performed on 85 patients undergoing the limb salvage operation with prosthetic replacement for tumors from January 1994 to December 2004. Ofthe patients, 21 (13 males and 8 females, aged 18-58 years) underwent reoperations for various reasons. All the diagnoses were pathologically confirmed(10 patients with osteosarcoma, 4 with chondrosarcoma, 5 with giant cell tumor of the bone, 2 with osteofibrosarcoma). The distal femur was involved in 9 patients, proximal tibia in 8, proximal femur in 2, proximal humerus in 1, and acetabulum in 1. According to the Enneking surgical grading system, there were 5 patients in ⅠB and 16 in ⅡB. The time between the first operation and the reoperation was 2 weeks to 20 years. The common reasons for the reoperation were tumor recurrence in 8 patients, prosthetic loosening in 5, no healing of the incision in4,joint dislocation in 3, and implant fracture in 1. The amputation and the prosthesis revision were respectively performed on 6 patients, extensive resection ofthe tumor on 3, the myo-skin flap translocation on 4, internal hemipelvectomy without reconstruction on 1, and open reduction on 1.Results The follow-up in18 patients for 1-5 years (average, 3 years and 4 months) revealed that 4 patients died of osteosarcoma with pulmonary metastasis. The other 14 patients had no tumor recurrence or loosening of the prosthesis, and the incisions healed well. The assessment on the joint function was performed on 13 of the 18 patients and the results were as follows: excellent in 2 patients, good in 5, fair in 4, and poor in 2, with a satisfaction rate of the reoperation with limb salvage of 84.6%and an excellent-good rate of 53.8%. Conclusion Tumor recurrence is the most common reason for the reoperation after the limb salvage with prosthesis for tumors, and loosening of the prosthesis is an important reason, too. By therules of the bone tumor limb savage, the limb salvage operations can also beperformed, which can achieve a satisfactory result of the limb function.
Giant thoracic tumor is currently one of the diagnostic and therapeutic challenges of thoracic surgery, with no established guideline or standard for diagnosis and treatment. The quality control of individualized surgical strategy and perioperative management with multi-disciplinary participation is the key to ensure the safety and improve the prognosis of patients. Based on the clinical experience of our institution and others, we hereby discussed and summarized the basic principles, surgical strategies and perioperative management of giant thoracic tumor, aiming to provide a reference of quality control.
Successrui treatment o? ? cases o? softtissue defect of the hand after explosive in-juries have been achieved by using free skinflap. Three to seven days after emergency de-bridement, repair was then carried out bytransfer of free vascularized anterolateralfemoral skin flap (in 4 cases) and lateralskin flap of the leg (in 2 cases). An experi-ence was introduced for primary repair of de-fect of the dorsum of the hand from a pene-trating injury by a skin flap of which the skin of the central portion was removeed with the preservation of the subcutaneous tissue and fascia.
【Abstract】 Objective To explore the cause of the perioprative period compl ication of scandinavian total anklereplacement(STAR) and to summarize the experience in the treatment and prevention. Methods From March 1999 toNovember 2006, 35 patients were given total ankle replacement(TAR) with STAR system. There were 19 males and 16 femaleswith an average age of 50.5 years (27 to 68 years), including 12 cases of posttraumatic arthritis, 8 cases of osteoarthritis and 15cases of rheumatoid arthritis. All patients had pain of ankle joint, swell ing and l imitation of joint motion. The disease coursewas 9-64 months. The curative effect was estimated by Kofoed total ankle scoring system. The mean preoperative ankle scorewas 29(6-48); the mean pain score was 18.3(0-35); the mean function score was 11.7(6-18); and the mean activity score was9.2(3-12). The type of all compl ications were record, and its cause, prevetion and treatment were analyszed. Results Thirtythreepatients achieved heal ing by first intention, 2 achieved delayed union because of infection. Twenty-eight patients werefollowed up 3-80 months (mean 43.5 months). Medial malleolus fracture occurred in 2 cases, unstable ankle joint introversion in2 cases, l imitation of ankle dorsiextension in 1 case and 1 case had hypoesthesia at intermediate dorsal skin of foot and 3rd-5thmetatarsal skin without obvious dysfunction; all were treated with symptomatic medication. The postoperative mean ankle scorewas 85.5 (58-95); the mean pain score was 48.3(35-50); the mean function score was 20.7(18-30); the mean activity score was17.2(16-20). There were statistically significant differences when compared with preoperative score(P lt; 0.01). The cl inical resultswere excellent in 16 patients, good in 9 patients and fair in 3 patients. The X-ray films showed no loosening and subsidence ofprosthesis. Conclusion Although STAR can retain the functions of the operated joint, it has its special compl ications. It isimportant to obey operation principle with proficient operative technique, to strictly control surgical indication and to intensifyperioperative period treatment so as to decrease the compl ications.
