[目的] 评价指动脉转位与静脉移植修复断指再植中血管缺损的临床效果。[方法] 2014年9月~2018年9月对本院153指伴血管缺损的断指进行断指再植术,其中采用指动脉转位技术94指,比较两组围手术期和随访资料。[结果] 采用指动脉转位技术94指中,同指动脉转位16指,邻指局部转位29指、邻指顺行转位24指、邻指逆行转位18指、虎口动脉转位7指;缺损长度平均(4.74±1.82) cm。静脉移植组59指,缺损长度平均(4.52±1.41)cm。指动脉转位组中7指出现动脉危象,其中4指再次探查吻合后成活,2指截除,1指部分坏死,总成活率96.81%。静脉移植组12指发生动脉危象,其中5指再次探查后成活,4指截除,3指部分坏死,总成活率88.14%,两组成活率比较差异有统计学意义(P0.05)。术后12个月,动脉转位组掌指关节、近侧指间关节和远侧指间关节ROM均显著大于静脉移植组,差异均有统计学意义(P0.05)。术后12个月按BMRC评级标准,动脉转位组再植断指的感觉功能显著优于静脉移植组,差异有统计学意义(P0.05)。[结论] 指动脉转位是修复再植动脉缺损的有效方案,不仅能提高再植指成活率,而且有利于术后神经功能和关节功能恢复。 相似文献

To improve visualization of the small vessels for distal bypass grafting, arteriograms of the lower extremity were obtained in 187 patients by use of active warming of the extremities, selective distal positioning of the catheter for contrast agent injections, and intraarterial administration of tolazoline. With these techniques, satisfactory visualization was obtained for planning of operation, and in only one patient was an intraoperative arteriogram necessary before bypass grafts were placed. 相似文献

Presented with the alternative of a bowl or bottle in which to void a urine specimen, patients often chose the unexpected, with mistakes far more frequent among women than men. The “positives” did not differ significantly from our general office population, but errors by women with medical orientation were numerous. 相似文献

The pediatric small vessel vasculitides reviewed in this article are Henoch–Schönlein purpura (HSP) and the anti-neutrophil cytoplasmic antibody-associated vasculitides (AAV). The new classification criteria for HSP and Wegener’s granulomatosis are now validated and will facilitate the conduct of future epidemiological studies and clinical trials. The clinical manifestations of small vessel vasculitis in children are described, and current therapies discussed. There is a lack of good clinical trial data on which to base therapy for HSP. Similarly, data based on randomized controlled trials (RCTs) for pediatric AAV are lacking, although children with AAV are for the first time now included in a RCT of mycophenolate mofetil versus cyclophosphamide. Significant challenges remain in the field of pediatric small vessel vasculitis, including the development of validated disease outcome measures and biomarkers to be used in clinical trials. Lastly, long-term outcome data are lacking in survivors of pediatric small vessel vasculitis. 相似文献

In many situations, temporary artery occlusion is an integral component of aneurysm surgery. The use of temporary clip may allow safer and easier aneurysmal dissection and clipping. Several points, concerning the duration and overall risks of temporary occlusion and the method of choice for cerebral function monitoring have to be discussed. MATERIAL AND METHODS: Non exhaustive review of neurosurgical literature. DISCUSSION: Temporary clip application decreases the risk of intraoperative aneurysmal rupture. The analysis of data published in the literature showed that several questions remain open concerning the optimal method of neuroprotection and cerebral function monitoring, as well as the limit of occlusion duration. Other clinical trials are needed to assess the efficacy and safety of this technique. 相似文献

Early diagnosis, expeditious vascular repair, and aggressive management of complications have resulted in an amputation rate of less than 9%. Repair rather than ligation of an associated femoral vein injury is commonly practiced by experienced trauma surgeons. In most circumstances, a reversed autogenous saphenous vein graft from the contralateral extremity is the conduit of choice; however, if a saphenous vein cannot be used because of size discrepancies, multiple associated trauma, or extensive contamination, polytetrafluoroethylene can be used with good results. If vein ligation is performed, early fasciotomy is indicated for close and meticulous monitoring of the compartmental pressures. Clearly, the most crucial components for a successful outcome are a thorough evaluation, early operation, and a flawless vascular repair. 相似文献

Trauma to the iliac vasculature continues to pose a significant challenge to management. In several large series, mortality for penetrating injuries is reported as approaching 40%. Uncontrollable hemorrhage originating from an anatomically inaccessible source and multiple associated injuries often contribute to this high mortality rate. This article discusses the current existing management strategies and the controversial role of PTFE in vascular reconstruction within a contaminated field. Concomitant injuries to the enteric viscera and genitourinary system are also addressed. Postoperative management including anticoagulation and the complications of liberal fasciotomy are mentioned. The evolving role of endovascular therapy as an adjunctive modality in the armamentarium of the trauma surgeon is also presented briefly. 相似文献

The management of lower extremity vascular injuries has undergone dramatic changes over the last century. With the optimal management of femoral and popliteal injuries established, controversy still exists with respect to management of vascular injuries below the popliteal fossa, in the shank arterial vessels. These injuries are uncommon, often limb threatening, and usually require complex management decisions. Incidence of shank vessel injuries, imaging studies required for accurate and expedient diagnosis, determinants influencing the decision for repair or amputation, and details of techniques in surgical intervention are discussed. 相似文献

Takayasu arteritis is a chronic granulomatous disease of the aorta and its major branches that usually affects women during
the second and third decades of life, but it has been reported in young children. This review details the clinical, pathological
and radiological features, differential diagnoses and management of the condition, focusing chiefly on the disease in children.
The recent definition of Takayasu arteritis is discussed. The condition should be considered in patients with unexplained
arterial hypertension or unexplained inflammatory syndromes without signs of localization. Since the disease may be life-threatening
and progressive, early recognition is necessary to initiate appropriate therapy. Patients with persistent ischaemic symptoms
including hypertension might benefit from revascularization procedures. 相似文献

During a 24 month period, 30 patients were treated for central vessel trauma (CVT). Injured vessels included all of the major arteries and veins in the chesk, neck and abdomen except the infrarenal aorta. Overall survival was 70 per cent. Experience with specific injuries is reviewed with commentary on surgical access to difficult areas including the thoracic outlet, suprarenal aorta and inferior vena cava. Common factors in the nine deaths are reviewed with the findings that cardiac arrest at any time during pre- or intraoperative management is uniformly lethal; emergency thoracotomy for control of bleeding carries an expectedly high mortality; cross-clamping of the descending thoracic aorta to control hemoperitoneum has a limit of tolerance of about one hour, and prolonged shock, whether compensated or profound is poorly tolerated and is associated with a high mortality. 相似文献
