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.
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.
目的探讨胆囊结石病引起胆道内瘘的原因,提高其诊断和治疗水平。方法收集我院1990~1999年收治的胆道内瘘患者46例,并对其病因、诊断与治疗进行分析。结果胆囊十二指肠瘘18例(39.1%),胆囊结肠瘘8例(17.4%),胆囊与胃、空肠内瘘各1例(4.3%); 胆囊胆管瘘18例(39.1%)。术后出现并发症4例(8.7%),死亡1例(2.2%),治愈率为97.8%。结论重视本病的临床表现及术前、术中检查,选择恰当手术方式,可减少死亡与并发症的发生。
Objective To evaluate the effect of Fogarty balloon catheter embolectomy on arteriovenous graft thrombosis in hemodialysis patients. Methods We retrospectively analyzed the clinical data of 11 patients who underwent maintaining hemodialysis and arteriovenous graft thrombosis through Fogarty balloon catheter embolectomy between March 2010 and November 2014. The thrombosed graft was incised, and a 4 or 6 French catheter was placed in the venous and arterial limbs of the graft respectively. The Fogarty balloon was passed beyond the thrombus and pulled out after saline was infused into the balloon, and the thrombus was taken out. The procedure was considered unsuccessful if the blood flow was not re-established or if the graft re-thrombosed within hours. Results The treatment was successfully performed in all the patients. Of the 11 patients, 3 received balloon dilation due to stenosis of venous anastomosis, and 2 received angioplasty due to underlying arterial anastomosis lesion. After corresponding measures were taken, the thrombus of all the 11 patients were taken out, and blood flow was recovered. Two to seven days after surgery, low molecular weight heparin was used for anti-coagulation. The blood flow of all arteriovenous grafts reached over 250 mL/min. All the patients were followed up for 4 to 30 months. During the follow-up, the arteriovenous graft remained functional in 5 patients; 4 patients had re-thrombosis on day 2, 3, 25, and 71 after surgery respectively; one changed to undergo peritoneal dialysis due to rupture and infection of the graft, and one patient was transferred to another hospital in another area and was not followed up any longer. The therapy was successful in 81.8% of this group of patients. Conclusion Fogarty balloon catheter embolectomy is effective in restoring patency of thrombosed arteriovenous graft in hemodialysis patients, and more studies are needed.
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。
At present, the whole lifecycle management of vascular access for hemodialysis in China is still in its early stages. Faced with a large group of chronic kidney disease patients, hospitals at all levels lack systematic and continuous nursing management models. To address the issue of lacking continuous and effective nursing management of vascular access for dialysis during the period from hospitalization for autologous arteriovenous fistula surgery to outpatient maintenance hemodialysis treatment, this article introduces the background, specific implementation methods, and preliminary results of the new model of integrated medical and nursing follow-up management of vascular access for patients with hemodialysis during hospitalization and outpatient period constructed by the Wenjiang Hemodialysis Center of West China Hospital, Sichuan University. The purpose is to explore a new model for continuous and effective management of vascular access for hemodialysis patients.
