title: Exhaustion of vascular endowment in hemodialysis: proposal for a permanent inlet access.
abstract: The subcutaneous reservoir is a new vascular access for patients on regular hemodialysis (HD). A double chamber in Titanium- Pirolytic Carbon with siliconic boreable superior caps is inserted in to a subcutaneous subclavian side, and always in subcutis connected to two siliconic catheters located in the right jugular resulting in the right atrium. The puncture of each chamber is performed with a special hemodialysis-cannula telescopically assembled on a "dilatation tube", in which a stylet is inserted. In correct sequence, the cutaneous planes and the caps are bored, dilated, and finally the HD cannula after sliding over the previous structures is positioned in the inner chamber, closing the HD circuit. In our study two patients were implanted, with a survival of 24 months, good compliance, no cardiovascular impairments and lack of catheteral pathology.
