Central vein obstruction in hemodialysis patients: Results of radiological and surgical intervention

Abstract

Symptomatic CVO in dialysis patients with AVFs can be treated with a high success rate through radiological intervention. Surgical reconstruction is an appropriate alternative method in case of failed PTA.

Endovascular treatment of occlusive central venous disease: one center's experience

“…1,[15][16][17][18][19][20][23][24][25][26][27][28] Additionally, also in common with other authors, 20,21 we did not observe superior patency in angioplasties with stents. Notwithstanding, our results differ with …”

“…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.…”

“…There are reports of primary patency at 6 months, varying from 23 to 55%. 1,[15][16][17][18][19][20] In 2007, in one of the largest studies of angioplasties for COVD undertaken to date, Bakken et al 20 studied 47 patients and demonstrated a technical success rate of 77%, with primary patency at 3 months of 58%, at 6 months of 45% and at 12 months of 29% (Table 2).…”

Treatment of Central Venous Obstruction in the Dialysis Patient: Patient Considerations and Treatment Options

“…To date, there have been no large randomized control or cohort studies to assess PTA for CVD, making it difficult to draw conclusions on the outcomes of PTA and make comparisons to alternative newer technologies. PTA has demonstrated a variable technical success rate ranging from 70% to 90% (Bakken et al, 2007;Beathard, 1992;Dammers, de Haan, Planken, van der Sande, & Tordoir, 2003;Glanz et al, 1988;Kovalik, Newman, Suhocki, Knelson, & Schwab, 1994;Quinn et al, 1995;Surowiec et al, 2004). A study by Kovalik et al (1994) made some interesting observations, including a technical failure rate of 7%, with greater than 50% improvement in 70% of patients with CVD with nonelastic lesions.…”

“…There is a 6-month primary patency range of 23% to 63% and a cumulative patency range of 29% to 100%. There is a 12-month primary patency range of 12% to 50% and a cumulative patency range of 13% to 100% (Bakken et al, 2007;Clark et al, 1990;Dammers et al, 2003;Glanz et al, 1988;Kovalik et al, 1994;Quinn et al, 1995;Surowiec et al, 2004). One of the largest studies to date on PTA for CVD by Bakken et al in 2007 composed of 47 patients demonstrated a technical success rate of 77%.…”
