A femoral-femoral bridge graft
was used for vascular access.
Rest were either expanded polytetrafluoroethylene (ePTFE) bridge grafts
(37) or bovine arteriovenous bridge grafts
(9).The ratio of using bridge graft
was quite high in this study.
Pulmonary hypertension was present in 41(60%) patients with AVF 3(27%) patients with tunnel cuffed catheter and 1 patient had AV bridge graft. Pulmonary hypertension was more common in females; present in 28 females (67%) and 17 males (45%) that was statistically significant (pless than 0.05).
Out of 80 patients enrolled 68 patients (85%) were having AVF 11 Patients (13.8%) had tunneled cuff catheter and 1 patient (1.3%) had AV bridge graft. In our study PH was present in 45 patients (56%).
Single-stage reconstruction of soft-tissue defects including the Achilles tendon using the dorsalis pedis arterialized flap along with the extensor digitorum brevis as bridge graft

On November 18, 2011, approximately two years post his initial injury and operation, the patient was taken back to the operating room for excision of his fistula, removal of his bridge graft and subsequent abdominal reconstruction using Trans-Abdominal Wall Traction (TAWT).
The entire bridge graft, with the exception of the areas adhered to the fascia, was removed, explanted, and sent for histology.
Three years later in 1969, the first of several modified AVFs were being used for vascular access--the saphenous vein bridge graft (Konner, 2005).
In the early 1970s, three new grafts materials were introduced: the bovine carotid artery biologic graft (see Figure 3); the Gore-Tex[R] graft (see Figure 4), a serf-sealing synthetic product made of expanded polytetrafluoroethylene (e-PTFE); and another synthetic product called a Dacron velour vascular bridge graft (Konner, 2005).
The average patency rate of a dialysis bridge graft
is 41%-75%; an arteriovenous fistula that's used for access has a slightly better patency rate.
One may select one of many grafting techniques including: whip, cleft, splice, and side grafts (see Figure 1) as well as bridge grafts
and budding (Hertz, 2014).
Despite efforts in recent years to maximize access, prosthetic bridge grafts
are still necessary in about half of patients, despite inferior patency results.
