“…Rates of immediate technical success of angioplasties conducted with a balloon alone can vary from 70 to 90%. 1,[15][16][17][18][19][20] In a study conducted by Kovalik et al, 16 in 1994, the authors observed that there were two types of central venous injuries: non-elastic lesions, which respond well to angioplasty, and elastic lesions, which do or do not respond to angioplasty. Therefore, elastic lesions tend to maintain less patency in relation to non-elastic lesions.…”

Introduction: The majority of cases of stenosis or occlusion of central veins are the result of central catheters, arteriovenous fistulas, neoplasms or traumas and these conditions can cause severe cases of venous hypertension or reduce the flow through fistulas. The objective of this study is to analyze the results of central venous angioplasties conducted at our hospital. Methodology: We conducted a retrospective and descriptive study to analyze the results of central venous angioplasties conducted from 2010 to 2012 at a university hospital run by the Universidade Estadual de Londrina, Brazil. We calculated primary and secondary success rates and analyzed whether or not stents were used and complications occurred during a 6-month follow-up period. Results: A total of 25 central venous angioplasties were conducted. Twenty-four (96%) of these were because of catheter-related intimal hyperplasia and one was to treat the effects of compression by a tumor. Fifteen (60%) angioplasties were to correct stenosis and ten (40%) were because of occlusions, with a one-hundred percent success rate for all stenosis-related procedures. However, none of the cases of occlusion could be treated endovascularly. Patency during the 6-months follow-up period was 80% after reinterventions. Conclusions: Despite good results observed after primary interventions for stenoses, it must be accepted that all current treatment options for chronic occlusive venous disease will, sooner or later, lead to restenosis or occlusion. Venous occlusions constitute a challenge demanding the development of new techniques and new materials. Prevention is paramount, through avoidance of central catheterization and early creation of arteriovenous fistulas.

“…Because early trials showed that the unassisted patency rate of AVGs did not differ with stenting than with PTA alone (40)(41)(42), stent placement was recommended only in the setting of elastic stenoses or PTA failure. However, a recent prospective study of 61 patients with thrombosed AVG reported significantly higher patency rates after placement of a nitinol stent compared with PTA alone (43).…”

SummaryHemodialysis vascular access dysfunction is a major source of morbidity for patients with ESRD. Development of effective approaches to prevent and treat vascular access failure requires an understanding of the underlying mechanisms, suitable models for preclinical testing, systems for targeted delivery of interventions to maximize efficacy and minimize toxicity, and rigorous clinical trials that use appropriate outcome measures. This article reviews the substantial progress and ongoing challenges in developing novel treatments for arteriovenous vascular access failure and focuses on localized rather than systemic interventions.

“…The management of central stenosis is evolving. Whenever found, endovascular balloon angioplasty should be attempted to a minimum of the contiguous uninvolved vein (Quinn et al 1995). Unfortunately, central vein stenosis tends to recur (Quinn et al 995, Kovalik et al 1994).…”
