ARTERIOARTERIAL PROSTHETIC LOOP: AN ALTERNATIVE APPROACH FOR HEMODIALYSIS ACCESS
Esmail Mahmoud Serag eldin;
Abstract
Vascular access failure causes substantial morbidity in patients with end-stage renal disease who require long-term hemodialysis. As standard vascular access, an arteriovenous (AV) fistula created with a superficial vein or a prosthetic AV access with a suitable deep vein are used.
Still, in some patients, veins can be exhausted owing to multiple long-term indwelling central vein catheters (CVC), transvenous pacemakers, or previously failed AV vascular access attempts.
Stenosis and occlusion of central veins can be treated surgically or by angioplasty to establish sufficient outflow required for AV access. Central subclavian vein obstruction can be reconstructed by different surgical techniques with good results. However, these procedures need a suitable jugular vein or undisturbed contralateral venous outflow.
Endovascular interventions for the treatment of central venous obstruction show excellent initial success, but primary patency rates for 1 year are < 50%, restenosis rates are high, and long-term results are uncertain.
Several uncommon procedures for maintenance of AV grafts at central venous obstruction have been published. However, some of these approaches appear inadequate for the creation of vascular access.
