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.
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。
The formation of an arteriovenous fistual for dialysis by routine interrupted sutures anastomosing the vein and artery is difficult to perform and time-consuming. A new method, telescopic adhesive anastomosis was studied and applied in 10 hemodialysis patients, who were in need of an arteriovenous fistula. The external diameter of the vessels anastomosed was 2.40 +/- 0.20 mm (radial artery) or 2.40 +/- 0.35 mm (cephalic vein). After thorough debridement of the vascular ends, the arterial end was put in the venous lumen. In order to fix the telescopic vessels, two stitches were applied 180 degrees apart from each other and tied. Each stitch was inserted from vein (penetrating the whole wall) to artery (just through the adventitia and partial thickness of the media vasorum). The distance from the stitch to the edge of the vein was 0.5 mm, and that of the artery was approximated to the external diameter of the vessle. The medical adhesive was then applied for sealing the anastomotic adventitia. Ten seconds were given for the solidification of the adhesive. The patients were followed up for 8 months. The patency rate was 100%, and the rate of blood flow was more than 300 ml/min (measured by ultrasonography). It was shown that this method could be managed easily and quickly, and the so-formed fistula would fulfill the need of hemodialysis.
目的探讨为维持性血液透析患者行肘部动静脉内瘘的手术方法及技巧。 方法回顾性分析我院2009年8月至2012年8月期间行肘部动静脉内瘘68例患者的临床资料。 结果68例患者手术均成功。所有患者术后血流量都能满足血液透析需要，无感染、皮下血肿等并发症。随访至今，未发现血管内血栓形成、造瘘口狭窄等。 结论对于腕部自体动静脉不能行造瘘术时，肘部动静脉内瘘为血液透析患者提供了一条新的血管通路。
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.
