  • Research on the Whole-course Standardized Care for Patients with Autologous Arteriovenous Fistula

    目的  研究自体动静脉内瘘全程规范化护理的可实施性及优势。 方法 制定自体动静脉内瘘全程规范化护理工作流程及标准,将2011年6月-8月经自体动静脉内瘘行维持性血液透析患者随机分为观察组(125例)和对照组(115例),分别予以全程规范化护理和普通护理,对比分析两组之间内瘘不良事件发生率、患者满意度、护士认同度等指标的差异。 结果 两组内瘘不良事件发生率分别为8.0%和21.0%,患者满意度分别为98.4%和84.3%,差异均有统计学意义(P<0.05);两组护士对本组护理模式认同度均为90.0%,差异无统计学意义(P>0.05)。 结论 自体动静脉内瘘全程规范化护理模式能有效降低内瘘不良事件发生率并显著提高患者满意度,值得临床推广。

  • MID-TERM RESULTS OF ARTERIOVENOUS AXILLARY LOOP GRAFT ON CHEST FOR ESTABLISHING HEMODIALYSIS ACCESS

    ObjectiveTo explore the role of arteriovenous axillary loop graft (AVALG) on chest for establishing hemodialysis access in patients with chronic renal failure. MethodsA retrospective analysis was made on the clinical data of 12 patients with chronic renal failure who underwent an AVALG on chest for hemodialysis access between December 2010 and May 2014. There were 2 males and 10 females with an average age of 65.25 years (range, 46-75 years). The main causes were chronic glomerulonephritis in 6 cases, diabetic nephropathy in 4 cases, and both kidney resection because of urinary tract tumors in 2 cases. The disease duration was 2-12 years (mean, 6 years). The 12 patients all underwent 5-14 times (mean, 7 times) failed prior vascular accesses [arteriovenous fistula (AVF)and arteriovenous graft (AVG)] leading to exhaustion of venous access sites on the upper extremities. ResultsThe AVALG on chest were functionally useful for hemodialysis access, 2-3 times per week, and the blood flow was 250-350 mL/minute; the average time for the first dialysis was 48 days (range, 42-93 days). All patients were followed up 12-54 months (mean, 20.92 months). There was no death during perioperative period. The primary patency rates at 6 and 12 months were 91.7% and 83.3% respectively, and the secondary patency rates at 6 and 12 months were both 100%. After operation, infection (1 case), thrombosis (2 cases), bleeding (2 cases), and swollen (1 case) occurred, which were all cured after corresponding treatment. ConclusionAVALG on chest is a supplementary option for chronic renal failure patients with inadequate upper extremity venous access sites after repeat occlusion.

  • Application progress of venous pressure monitoring in arteriovenous fistula

    Venous pressure monitoring is an important indicator for the arteriovenous fistula evaluation. Direct static venous pressure monitoring is recognized as the most accurate way of venous pressure monitoring, which is widely used in the functional monitoring, functional evaluation of arteriovenous fistula, the diagnosis of complications and the evaluation of surgical efficacy. Venous pressure monitoring has obvious advantages and disadvantages, so it is necessary to improve relevant knowledge to correctly guide clinical diagnosis and treatment. In this paper, the study of static venous pressure monitoring of arteriovenous fistula was summarized, in order to improve the understanding of the significance and clinical application of static venous pressure monitoring of arteriovenous fistula.

  • 超声引导在血液透析内瘘穿刺点压迫止血中的临床应用

    目的 探讨超声引导在血液透析内瘘穿刺点压迫止血中的临床应用。 方法 回顾性分析 2008 年 8 月—2015 年 10 月 36 例超声引导下血液透析内瘘穿刺点压迫止血的临床特点。36 例患者均为应用常规止血方法失败,而在超声引导下采用小方块形折叠纱布定点、垂直压迫出血点止血。 结果 36 例患者均使用超声引导定位法准确找到出血点,在 15~50 min 之内有效止血。 结论 超声引导小方块形折叠纱布定点、垂直压迫出血点止血法简单、安全、有效,为临床提供了又一实用的止血方法。

  • The Value of Ultrasound Evaluation and Marking before Arteriovenous Internal Fistula in Uremia Patients

    ObjectiveTo explore the value of ultrasound evaluation and marking before arteriovenous internal fistula in end-stage renal disease hemodialysis patients. MethodsTwenty-five uremia end-stage patients were admitted into our nephrology department from January 2012 to July 2012. All of the patients had encountered several times of fistula failure or had difficulty in establishing the forearm arteriovenous fistula. We focused on observing the brachial artery, radial artery, cephalic vein, the basilica vein and great saphenous vein. We measured the diameter of the vessels and marked the trend of arteries and veins in the body surface under the ultrasonic navigation. Our goal was to look for appropriate bypass vessels in the elbow and the upper arm. ResultsFourteen patients had endured several times of fistula failure. Among the 14 patients, 9 patients completed the surgery of reengineering fistula and autogenous great saphenous vein transplantation, 2 accepted artificial vascular transplantation, 1 completed the removal of blood clots in the left upper limb artificial blood vessels and arteriovenous internal fistula molding, and 2 gave up surgery. Eleven patients could not complete the arteriovenous fistula operation for the fine forearm superficial vein. Of them, 2 patients accepted artificial vascular operation, 6 underwent autogenous great saphenous vein transplantation, 1 with slender radial artery in diameter completed higher position fistula between the brachial artery and median cubital vein, and 2 gave up surgery. ConclusionArteriovenous internal fistula preoperative ultrasound assessment and marking have very important value in improving the success rate of operation in end-stage uremia patients.

  • The interventional treatment of venous hypertension associated with autogenous arteriovenous fistula

    Objective To investigate the clinical effect and safety of balloon angioplasty (BAP) for patients with venous hypertension associated with autogenous arteriovenous fistula (AVF). Methods Thirty-three patients with venous hypertension associated with AVF were hospitalized between August 2012 and August 2014 in the Department of Nephrology, West China Hospital of Sichuan University. All of the patients received BAP therapy. The clinical characteristics and therapeutic effects were comparatively summarized before and after operation. Results Venous hypertension in all the 33 patients was caused by central venous stenosis or occlusion. Among them, there were 13 cases of stenosis on the site where the left innominate vein crossed the aorta, 10 cases of stenosis at the junction of the left innominate vein and superior vena cava, 4 cases of stenosis at the junction of the left subclavian vein and the innominate vein, 3 cases of right innominate vein stenosis, and 3 cases of innominate vein occlusion. The lesions were most common in the innominate vein. Innominate vein stenosis or occlusion occurred in 19 cases (57.6%), and stenosis at the junction of innominate vein and the superior vena cava or subclavian vein occurred in 14 cases (42.4%). Of the 33 patients, one patient with complete occlusion of the innominate vein did not receive BAP treatment because guide wire could not pass through the occlusion site. The other 32 patients underwent BAP treatment, among whom 30 (93.8%) were successful, and 2 (6.2%) failed. No obvious complications occurred. One day after BAP treatment, patients’ symptoms were significantly relieved. One to seven days later, swelling of the hands, pain, and other symptoms were relieved. In the 30 patients who underwent the treatment successfully, 29 were followed up for 3 to 24 months. Among them, 21 (72.4%) maintained clinical remission and the AVFs were functional, 6 patients (20.7%) got a restenosis later, and 2 patients died. Conclusions BAP is effective and safe for venous hypertension associated with AVF. However, the follow-up of patients has displayed the possible risk of restenosis in long-term outcomes.
