APPLICATION OF CROTCH-SHAPED VEIN GRAFTS IN REPAIRING DEFECTS OF THEVESSELS WITH A LARGE DIAMETER

Objective To investigate the results and applicationvalue of crotch-shaped vein grafts in repairing defects of the vessels with a large diameter.Methods From June 1998 to October 2003, 35 cases of vesseldefects with a large diameter were repaired with crotch-shaped vein graft (29 males and 6 females,aged 18 to 45 years with an average of 25.7 years ). The locations of defects were femoral artery in 25 cases, popliteal artery in 2 cases, femoral vein in 7 cases, and subclavian vein in 1 case. The interval between injure and operatioinwas 1-8.5 hours (4.1 hours on average).The blood flows of trouble and healthy vascular were determined with Doppler detector and compared preoperatively andpostoperatively. Results All the anastomotic stomas were patent in 35 cases. Thirty-one cases were followed up 6 weeks to 24 months (9.5 months on average), the patent rate was 100%, no case occurred vasospasm or tromboembolism; 2 cases occurred stomal leak and became hematoma, 3 cases occurred muscular necrosis, and the 5 cases achieved primary healing after secondary operation. The Doppler results showed that there was statistically significant difference in the blood flow betweenpostoperation and preoperation (Plt;0.01), but no statistically significant difference when compared the trouble vascular after operation with healthy vascular (Pgt;0.05). Conclusion The methodof crotch-shaped vein grafts is safe and effective in repairing defects of vessels with a large diameter,which is easy to draw materials and handy to operate. It has a promising value in clinical application.

ARTIFICIAL VASCULAR PROSTHESIS IN THE REPAIR OF ARTERIAL INJURIES OF THE EXTREMITIES

From June, 1987 through June, 1994, 126 cases of injuries of major arteries of the extremities were treated, in which Nationedmade Teflon artificial vascular prosthesis was used to repair in 20 cases. Eighteen of the twenty cases were operated immediately after initial injury and the other two had secondary operation. The sites of the original injuries were as follows: the external iliac artery in 1, femoral artery in 15, popliteal artery in 2 and the brachial artery in 2. The length of the defect of the artery was measured from 3 to 12cm. In 2 of 20 cases, the artificial vascular prosthesis was used because of the failurs of primary repair from autogenous saphaneous vein graft. The shortterm patency rate was 100 per cent and the longterm patency rate was 95 per cent. The diagnosis of vascular injury, the properties of the artificial vascular prosthesis and the points important in operation were discussed.

无骨折指体血管损伤的修复

目的 探讨无指骨骨折指体血管损伤后的临床处理及效果。 方法 1998年10月～2005年12月，根据指体血管损伤的程度，分别对56例62指采用直接修复血管神经肌腱、截骨短缩指骨、移植血管加腹部皮瓣移位三种方法进行修复。其中男38例42指，女18例20指；年龄18～40岁，平均29岁。皮带卷轧伤18例，纺纱卷伤16例，绳子勒伤16例，其他6例。拇指12指，食指18指，中指16指，环指10指，小指6指。术后按断指再植的术后处理，移位皮瓣修复者患侧肢体与躯干用绑带捆绑固定，注意观察皮瓣有无扭转。结果 采用直接吻合血管和截骨短缩指骨修复的44例50指，成活49指，成活率98％；采用移植血管加腹部皮瓣移位修复的12例12指，指体皮瓣均成活。成活的61指经6~12个月随访，根据断指再植评定标准，优35指，良15指，差8指，劣3指，优良率82％。结论 对无指骨骨折指体血管损伤，应根据血管损伤程度采用不同方法修复，能保留指体及恢复功能。

Progress of Non-Invasive Arterial Measurements and Evaulation of Cardiovascular Injury of OSAHS

阻塞性睡眠呼吸暂停低通气综合征( OSAHS) 是心血管疾病的独立危险因素[1,2 ]。睡眠过程中反复发生氧饱和度降低和频繁觉醒是心血管损伤的病理生理基础。OSAHS 血管损害的早期改变可表现为血管僵硬度增加, 对亚临床血管病变患者开展早期动脉弹性功能检测及早进行干预, 可有效预防心血管疾病的发生。本文就常用的无创动脉硬化检测lt;br /gt;技术及其对OSAHS 心血管损伤的评估相关研究进展进行综述。

DIAGNOSIS AND TREATMENT OF VASCULAR INJURY IN LIMBS

To report the diagnosis methods and cl inical treatment effects of blood vessel trunk damage in l imbs. Methods From January 2001 to June 2006, 72 patients with vascular injury in l imbs were treated. There were 50 males and 22 females, aged from 5-60 years (median 39 years) and including 44 cases of open injury and 28 cases of closed injury.The locations were subclavian artery in 1, femoral artery in 23, popl iteal artery in 20, radia artery and ulna artery in 12, brachial artery in 11, axilary artery in 3 and anterior and posterior tibia artery in 2. The disease course was 30 minutes to 27 days. Injured arteries were repaired by suturing directly in 3 cases, by end-end anastomosis in 39 cases and by saphenous transplantation in 30 cases. The length of transplant veins was 3 cm to 8 cm. Results In 72 cases, 67 survived and 5 were given amputation. Fortyeight cases were followed up 6 months to 5 years. The blood flow rate and the diameter of blood vessel on the affected l imbs were not different from that of normal l imbs by colorful Doppler blood flow monitor. Forty cases recovered satisfactory l imb function. Eight cases had different degrees of dysfunction, of them, four cases received functional reconstructive operation, and the function and appearance were improved. Conclusion To investigate the mechanism and situation of injury, to examine patients carefully and analyze comprehensively are the key points of making earl ier diagnosis for branch blood vessel damage; microsurgical repair of the injured blood vessel is the assurance of the blood flow rate. For the blood vessel above elbow and knee injured and lacked blood supply more than 4 hours and fascia syndrome, earl ier opening the fascia cavity is the effective methods to recover the function of the l imbs and to avoid disabil ity.
