The methods evaluated are horizontal mattress suture with subanular pledgets, horizontal mattress suture with supraanular pledgets and continuous running suture. <strong>Methods</strong>: Thirty hearts were explanted from newly terminated pigs. The hearts were randomized in the three groups. After an atriotomy, the mitral valve was cut out, and a patch was sutured into its place. An air pump model was connected to a balloon which was placed in the left ventricle through aorta and continuously filled with air to a maximum of 300 mmHg. The peak pressure at rupture was noted. If no rupture occurred before reaching 300 mmHg, the suture was found competent. <strong>Results</strong>: Two out of ten hearts in the continuous running suture-group had myocardial rupture within a pressure of 300 mmHg. In the remaining eight hearts there were no ruptures within 300 mmHg. In the two groups sutured with horizontal mattress with pledgets placed either subanular or supraanular, no rupture of myocardium occurred. When comparing continuous running suture with the horizontal mattress with subanular pledgets or the horizontal mattress with supraanular pledgets, the 1-sided Fishers’ exact was 0.237. At 5% significance level, there was no difference between the three suture methods. <strong>Conclusion</strong>: There was no statistically significant difference between the durability of the three suture methods, though rupture was only evident in the continuous running suture line. Since it is the surgeon’s choice to select the optimal suture technique, our study should be a reminder for the surgeon to reflect on the suturing factors that have an influence on successful mitral valve replacement.展开更多

The use of silicone implants in rhinoplasty has been widely used in China for many years, but is not suitable for patients seeking Caucasian tip shapes. The creation of an excessively high tip supported only by a silicone implant inevitably leads to implant extrusion. Although many rhinoplasty techniques have been used in Caucasian patients, there is currently no suitable method for Chinese patients, whose anatomy differs from that of Caucasians. The present study was aimed to investigate the clinical outcome of a novel method of rhinoplasty in Chinese people. Methods Eighty patients underwent rhinoplasty using our method between 2002 and 2006. We classified the patients into three types, according to the distance between tip defining points, and used different techniques accordingly. Furthermore, an innovative cartilage carving method and a tip fibro-fatty tissue flap were designed and combined with traditional techniques, such as insertion of silicone implant, cartilage grafts, suture techniques and cephalic trimming to reshape the nasal contours. The followup period was 10-60 months (average, 21 months). Results Remarkable modifications in nasal contours were achieved. No complications developed in any of the 80 patients. Seventy-eight patients were satisfied with the results. The outcomes remained unchanged over time. Conclusion Our method is effective and suitable for the treatment of Chinese patients with lower dorsa and bulbous nasal tips.展开更多

文摘Background Currently,adhesive technique is popular in vascular repair but not widely used for defective vessels.This study aimed to determine the feasibility and effectiveness of repairing defective vessels with 2-octyl-cyanoacrylate and a homemade prosthetic component.Methods Homemade prosthetic component consisting of expanded polytetrofluoroethylene (ePTFE),terylene film,and homemade soluble hollow stent mixed with adhesive can replace autologous graft and suture in repairing defective vessels,can fix vessels better using the stent without occlusive bleeding.Forty male mongrel dogs were used,20 for biomechanical tests and 20 for animal experiments.In the biomechanical test,dogs were randomly divided into two groups (n=10 each),one group repaired on the two sides of the carotid arteries with 2-octyl-cyanoacrylate and homemade component and another group repaired with suture and ePTFE.Of the 40 specimens,10 were used for adhesive and 10 for suture specimens for tension strength test,whereas the remaining specimens were used for bursting pressure test.In animal experiments,dogs were also divided into adhesive and suture groups (n=10),only of the left carotid artery.Recording the operational time,bleeding or not.Vessels were tested using color Doppler ultrasound,the inner diameter was measured,and the degree of stenosis at 8 weeks was evaluated digital subtraction angiography (DSA) were also performed.Specimens were then analyzed histologically.Results In the adhesive and suture groups,the specimens could afford atension strength of (23.80±1.51) N versus (24.60±1.08) N (P >0.05),the bursting pressure was (52.03±.2.43) kPa versus (50.04±3.51) kPa (P >0.05),and the mean time of anastomosis was (15.20±0.55) minutes versus (25.97±0.58) minutes (P <0.05).One dog in the adhesive group was bleeding from the suture.One dog from each group presented with thrombosis at 1 week.After measuring using ultrasound,the stenosis degree of all dogs were no more than 30% except the two thromboses.DSA and histological observation showed no obvious difference between the two groups.Conclusion Defective vascular anastomosis with 2-octyl-cyanoacrylate and our homemade prosthetic component is feasible,effective,timesaving,and easy to master.

文摘Background Anterior glottic web is one type of laryngeal stenosis.Previous surgical methods had some drawbacks,such as large surgical trauma,long postoperative recovery time,and multiple-stage surgery.This study aimed to explore better treatment to repair anterior glottis web.Methods We performed vocal cord mucosal flap procedure on 32 patients with anterior laryngeal webs.All subjects received vocal cord scar releasing and vocal cord mucosal flap repair and suture under general anesthesia with selfretaining laryngoscope.Results All 32 patients completed surgery in one stage,without postoperative laryngeal edema,difficulty in breathing,or other complications.After the surgery,the anterior commissure of vocal cords recovered to a decent triangle shape in 28 patients; however,in four patients there were 2 to 3 mm adhesion residuals on the anterior ends of the vocal cords,accompanied by scar appearance of bilateral vocal cords.The GRB score,voice handicap index scores,and maximum phonation time score significantly improved in all patients after the surgery.There was no evidence of recurrent laryngeal webbing in the 6-rnonth follow-up.Conclusion Vocal cords mucosal flap repair surgery has the advantages of less trauma,quick recovery,and significant improvement of the voice in the treatment of laryngeal webs.
