How long does a basilic vein transposition take?
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 is transposition of basilic vein?
The conventional surgical technique of basilic vein transposition consists of dissection and mobilizing the basilic vein at the medial side of the upper arm. After dissection, the basilic vein is transposed to a subcutaneous tunnel on the anterior surface of the arm and anastomosed to the brachial artery [10,11].
What is forearm vein transposition?
Forearm Looped Transposition When the distal radial and ulnar arteries are not appropriate for fistula creation but either the cephalic or basilic vein in the forearm is of appropriate size, a looped forearm vein fistula can be created. Either the basilic or the cephalic vein can be used in this situation.
Where is the cephalic vein?
The cephalic vein, along with the basilic vein, is one of the primary superficial veins that drain the upper limb 1. It courses through both the forearm and arm and terminates by draining into the axillary vein.
What is AV fistula transposition?
The arteriovenous fistula transposition is based on a first-stage proximal radial artery to median cubital vein arteriovenous fistula. Transposed brachial veins were elevated and positioned anteriorly to the incision to avoid repeated needle access through the surgical scar (Fig 2).
What is meant by 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.
Is basilic vein thrombosis a DVT?
DVT-UE must be distinguished from thrombosis of the superficial veins, i.e., the cephalic and basilic veins (1). Idiopathic DVT-UE and cases due to anatomical variants are known as primary DVT-UE.
Why is the cephalic vein in the arm?
The cephalic vein is a superficial vein of the upper limb and it’s one of the two main veins of the arm. Its name derives from ‘cephalic’ meaning head, as the vein runs up to the shoulder….Cephalic vein.
|Source||Dorsal venous network of the hand|
|Drainage area||Radial parts of the hand, forearm and arm|
Is cephalic vein considered deep?
The upper extremity veins are divided into the superficial and deep venous systems (figure 1). Superficial veins — The main superficial veins of the upper extremity include the cephalic, basilic, median cubital, and accessory cephalic veins (figure 1).
How serious is steal syndrome?
Hemodialysis access-related hand ischemia or ‘steal syndrome’ causes problems such as hand numbness, pain, coldness and weakness, as well as significantly reduced blood flow/pressure to affected tissues. In extreme cases, it can cause tissue death (gangrene), which may lead to the loss of fingers.
