  ABSTRACT: The objective of this study was to analyze the long-term outcome of 51 patients with brachial-jugular grafts for dialysis. Age, presence of diabetic nephropathy, complications of the angio-access, and therapeutic methods of treating complications were analyzed. All surgical procedures were performed under local anesthesia in an ambulatory surgical setting. The duration of angio-access was analyzed using the life-table method. Our results showed that brachial-jugular grafts can be performed under local anesthesia and in an ambulatory surgical setting. This procedure can be an alternative to complex intrathoracic procedures, Dacron cuff catheters, or lower limb grafts, in cases of stenosis or occlusion of the subclavian vein.

  ABSTRACT: We describe a 56-year-old woman who received dialysis through a right jugular catheter and developed a progressive right breast enlargement 1 year after arteriovenous graft shunt construction in the right forearm. Arm edema was not observed. A fistulography showed retrograde long thoracic and lateral thoracic veins flow secondary to a right brachiocephalic vein occlusion. Breast enlargement disappeared completely 2 weeks after a transfemoral balloon angioplasty and stent placement.

  ABSTRACT: To show the long-term results of 97 politetraflouroethylene dialysis grafts submitted to a graft by-pass to treat graft-vein stenosis. Venous stenoses were studied and diagnosed by means of fistulography in cases with fistula dysfunction or during surgery for graft thrombectomy. Both early and late complication rates were studied, as well as primary and secondary patency rates. Number of cases, 97. Mean age, 58 years (7-79). Diabetic nephropathy: 19.5%. Types of grafts in which stenoses developed: straight forearms 13; loop forearm 9; 6 mm upper arm 36; 6-8 mm upper arm 34; brachio-jugular 4; femoro-femoral 1. Overall follow-up time: 2,427 graft-months. Mean follow-up time: 21 +/- 5 months. Late complication rate: 0.30 episodes per graft-year of follow-up. Re-stenosis rate: 0.12 graft-year of follow-up. Primary cumulative patency rate: 70%, 62%, 51%, 45% at one, two, three and four years, respectively. Secondary cumulative patency rate: 87%, 79%, 74% and 71% at one, two, three and four years, respectively (p < 0.0016). No differences were observed between secondary patency observed after by-pass to treat dysfunction or thrombosis (p = 0.09259). In our experience, by-pass to proximal vein is associated with good results both at short and long term, probably because the intimal hyperplasia area is excluded and because by-pass is performed on an already dilated vein. The procedure can be performed under local anesthesia and in an outpatient basis between dialysis, with little discomfort for the patient.
