The large diameter of the stent-graft device (22 25 Fr) requires a surgical cutdown to expose the common femoral artery, but recently TEVAR can also be performed with a completely percutaneous access with the use of percutaneous access closure devices.
To describe the use of an innovative 5-part Percutaneous Access Needle with Glidewire (5-PANG), a novel technique in an attempt to make percutaneous nephrolithotomy (PCNL a routinely performed procedure) tract establishment a fast, safe, and less cumbersome procedure.
If an efferent or afferent loop was not marked with clips, patients underwent CT or CT IVCs, choosing the shortest loop which had an anterior location with safe percutaneous access on the basis of the CT.
Percutaneous access is an option in such patients, and the clinical staff can perform it.
Preliminary results of the use of a low-profile design that allows percutaneous access are presented.
Early CT (A, B) showed circumscribed effusion abutting the CFA at the level of percutaneous access, which was interpreted as a minor bleed and treated conservatively.
A noninferiority trial design was chosen to compare percutaneous access with standard open femoral exposure.
Next, percutaneous access was achieved with the aid of a C-arm fluoroscopic device, with the patient in the prone position, using an 18-gauge needle and a guidewire.
The Superion device is a single-piece, self-expanding titanium implant that is delivered via percutaneous access and deployed between the spinous processes of the symptomatic vertebral levels.
Between January 1986 and December 2007, 63 patients required percutaneous access to the biliary tree.
