What is a basilic vein transposition used for?
BVT is an alternative method with excellent initial maturation and functional patency rates requiring less extensive skin incision and surgical dissection. It is the most durable hemodialysis access procedure for those patients having multiple forearm AVF surgeries.
What is a transposed AV fistula?
This arteriovenous fistula transposition is based on a first-stage proximal radial artery to radial vein arteriovenous fistula. The transposed brachial vein is elevated anteriorly to the incision to avoid repeated needle access through the surgical scar.
What is Second Stage basilic vein transposition?
In two-stage procedures, the basilic vein is mobilised through a transverse antecubital fossa incision followed by creation of the fistula. Following a period of 4–6 weeks necessary for maturation, the second stage involves mobilisation of the basilic vein through two longitudinal skip incisions (Fig.
What does vein transposition mean?
CONVENTIONAL BASILIC VEIN TRANSPOSITION (BVT) After dissecting the basilic vein up to axillary vein, it is cut in the cubital fossa and transposed into the subcutaneous tissue by multiple small incisions. End to side basilic vein brachial artery anastmosis is done.
What is meant by the term transposition?
Definition of transposition 1a : an act, process, or instance of transposing or being transposed. b : the transfer of a segment of DNA from one site to another in the genome. 2a : the transfer of any term of an equation from one side over to the other side with a corresponding change of the sign.
What is cephalic vein transposition?
The option for cephalic vein transposition (CVT), described by Chen et al., involves surgical revision to redirect the blood flow to the adjacent patient veins.
How deep is the basilic vein?
As it ascends the medial side of the biceps in the arm proper (between the elbow and shoulder), the basilic vein normally perforates the brachial fascia (deep fascia) above the medial epicondyle, or even as high as mid-arm….
What is a basilic vein?
The basilic vein receives tributaries from the ulnar component of the dorsal venous network. It runs up the posterior surface of the forearm and curves around the ulnar border below the elbow to the anterior surface of the forearm. In the elbow, it is joined by the vena mediana cubiti, a branch from the cephalic vein.
What is cephalic vein stenosis?
Cephalic arch stenosis is considered one of the commonest cause of dysfunction in a brachiocephalic fistula which involves the cephalic vein in the region of the cephalic arch prior to junction with the axillary vein.
What is the rule of transposition?
In traditional logic the reasoning process of transposition as a rule of inference is applied to categorical propositions through contraposition and obversion, a series of immediate inferences where the rule of obversion is first applied to the original categorical proposition “All S is P”; yielding the obverse “No S …
What is the risk of drawing blood from the basilic vein?
Under the basilic vein runs an artery and a nerve, so puncturing here runs the risk of damaging the nerve or artery and is usually more painful. DO NOT insert the needle where veins are diverting, because this increases the chance of a haematoma. The vein should be visible without applying the tourniquet.
Is basilic vein transposition possible in a fistula?
Though basilic vein transposition is well established in multiple failed fistulae’s and obese patients, it requires large incision and morbidities like edema and infection. To avoid such compilations we, at our institution, adopted a small incision technique using two small 3-4 cm incisions.
Is the no-touch technique used to create basilic vein transposition-radial artery fistula?
Materials and methods: The no-touch technique was used to created basilic vein transposition-radial artery fistula in 22 patients. Another 30 patients received surgeries for RC-AVF.
When is autogenous arteriovenous access recommended for basilic vein transposition?
In spite of troublesome comorbidities associated with basilic vein transposition (BVT), it is still the most preferred technique when autologous veins … Primary use of the autogenous arteriovenous access is recommended by the National Kidney Foundation-Dialysis Outcomes Quality Initiative guidelines.
How are postoperative complications of basilic vein transposition (BVT) distributed?
Distribution of postoperative complications of basilic vein transposition (BVT) fistulae in relation to surgical technique (one or two-stage procedures) on both, intention to treat and per protocol analysis. Some patients had more than one complication. CI: confidence interval.
