Excelsior xt27

In each case, patients had given written informed consent at least 24 hours before the procedure after being informed about the intended treatment and potential alternatives.
All treatments were performed under general anesthesia using bi-plane digital subtraction angiography (DSA) units (Axiom Artis, Siemens, Erlangen, Germany). A 6F short sheath with a 6F guiding catheter was used via right-sided femoral access as the standard approach. In cases with severe vessel elongation and the need for an intermediate catheter, an 8F right femoral approach was used. Heparin was administered intravenously immediately after groin puncture (usually 3,000 IU unfractionated heparin IV). All flushing solutions, including the guiding catheters and microcatheters, were heparinized (5,000 IU unfractionated heparin/l).
The p64 was deployed via an Excelsior XT27 (Stryker Neurovascular, Kalamazoo, MI, USA) microcatheter. The diameter and length of the p64 were chosen based on intraprocedural 2D and 3D calibrated measurements of the diameter of the parent artery, the distance between the proximal and distal landing zones, the discrepancy of the diameter between the landing zones, and the aneurysm neck size taking into account potential device foreshortening. Once satisfactory deployment and positioning were achieved, the p64 was mechanically detached.

All treatments were performed in patients under general anesthesia with a 6 F guiding catheter or 8 F guiding catheter with a 5 F intermediate catheter in cases of severe vessel elongation, with guidance provided by bi-plane digital subtraction angiography (DSA) (Axiom Artis, Siemens, Erlangen, Germany; Azurion, Philips, Eindhoven). The standard approach included femoral access using short sheaths, predominantly on the right side. All FDs were deployed via Trevo Pro 18, Excelsior XT27 (Stryker Neurovascular, Kalamazoo, MI, United States), Headway 21 (MicroVention Terumo, Tokyo, Japan) or Prowler Select Plus (Cerenovus, Johnson & Johnson, New Brunswick, NJ, United States) microcatheters.
All patients undergoing FD procedures received intravenous administration of 3,000–5,000 IU heparin. Heparinized irrigation solutions were used in all catheters (5,000 IU unfractionated heparin/L). FD implantation was performed by the two most experienced interventionalists at each center.

All procedures were performed with the animals under general anaesthesia with acepromazine (0.2 mg/kg, intramuscularly), Telazol (5 mg/kg, intravenously), and maintenance with 2% isoflurane. The right common femoral artery was surgically exposed and a 6-Fr introducer sheath inserted. Using a 5-Fr vertebral catheter and standard 0.035-in. guidewire, angiography of the common carotid arteries (CCAs), external carotid arteries (ECAs), and subclavian arteries (SAs) was performed. After full heparinisation and activated clotting time 2–2.5 times the normal value, a 0.027-in. Marksman microcatheter (Medtronic, Dublin, Ireland) or Excelsior XT 27 (Stryker, Kalamazoo, USA) with 0.014-in. microwire was used to access the supra-aortic vessels.
