The bridging stents were positioned so that 3 to 4 mm of the stent graft protruded into the aortic lumen and were inflated with a balloon to 10 bar. The sheath was advanced over the balloon during balloon deflation to facilitate advancement of the flaring balloon. The protruding segments were flared with 9 mm diameter, 20 mm length balloon (Mustang, Boston Scientific, Marlborough, Massachusetts) for the renal artery stents (implanted through 6 mm diameter fenestrations), and a 10 mm diameter, 20 mm length balloon for the mesenteric stents (implanted through 8 mm fenestrations). The proximal marker of the flaring balloon was advanced to the level of the fenestration markers and the balloon was inflated to 10 bar. Positive forward pressure was applied on the shaft of the balloon to position it horizontal to obtain a 360° flair of the aortic portion of the bridging stent. Intraoperative data on procedure length, fluoroscopy time, dose area product (gray-centimeters squared [Gy·cm2]), volume of contrast agent injected, stent-related events, and additional procedures were collected.

TIPS Creation with Viatorr Stent-Graft

All patients underwent routine clinical and laboratory examinations prior to TIPS-creation. TIPS-creation was performed under combined ultrasound and fluoroscopic guidance with placement of a 10 mm Viatorr stent-graft (Gore Medical, Flagstaff, Arizona, USA) between the right hepatic vein and the right portal venous branch. Balloon dilatation was performed to an effective diameter of 8 to 10 mm with a non-compliant balloon (Mustang, Boston Scientific, Galway, Ireland) based on the individual needs of the patient with the goal to reduce the portosystemic gradient by half (ideally below 12 mmHg).

All procedures will be performed in a hybrid operating theatre using standard
percutaneous techniques under local anaesthesia. Unfractionated heparin (2000
iu) will be used for peri-procedural anticoagulation. An initial fistulogram
will be obtained. The stenosis will be crossed with a 0.018″ guidewire (Boston
Scientific, Marlborough, MA, USA) and support catheter. Mandatory pre-dilatation
of the target lesion with a standard high-pressure non-compliant balloon
(Mustang®, Boston Scientific, Marlborough, MA, USA) for 2 min,
will be used to match the calibre of the adjacent normal vessel. The Selution
SLR™ SCB will then be inserted and inflated for 2 min to rated burst pressure of
10 ATM, which according to the design specifications of the SCB will allow
maximal drug transfer to the vessel wall. Balloon length shall be chosen to be
at least 2 cm longer than the area treated during pre-dilatation (1 cm overlap
proximal and distal) in order to avoid geographical miss. No post-dilatation
will be allowed.

Evaluation of Balloon Catheter Performance

Three balloon catheters of 6 and 8 mm in diameter widely used in percutaneous transluminal angioplasty (PTA) procedures were tested: Mustang (Boston scientific, Natick, MA), Conquest (BD, Franklin lakes, NJ), and Genoss PTA (Genoss, Suwon, Korea). Mustang and Genoss are semicompliant balloon catheters, and Conquest is a non-compliant balloon catheter [21] [22] [23] [24] . The name of the manufacturer and size of balloon catheters and their nominal pressure and RBP experimented in this study are presented in Table 1.
This experimental study employed cylindrical modules made of transparent acrylic material to simulate the vessel wall. Because the transparent acrylic material has little elasticity and cannot simulate the elasticity of the vessel wall of the human, we experimented with two types of cylinders for each balloon diameter to simulate both extremes: tight and loose cylinders.

Ultrasound-Guided Percutaneous Transluminal Angioplasty

All PTA procedures were performed under ultrasound guidance. Briefly, the patient was administered local anesthesia; a 6-F vascular sheath (Terumo Inc., Japan) was inserted into the vessel, and 20 mg of heparin was injected. A 0.035-inch guidewire (Terumo Inc., Japan) was introduced, and the lesion was traversed under ultrasound guidance. In most cases, the tip of the guidewire was delivered at the level of the proximal arteries (e.g., brachial artery) to ensure stability of the working guidewire. A high-pressure balloon (Mustang, Boston Scientific Inc., USA) of appropriate size (usually 5–7 mm for veins) was placed along the guidewire to dilate the lesion, and the balloon was brought to the working pressure (usually 10 atm × 60 s). If the ‘girdle sign’ or residual stenosis >30% was still visible, the balloon pressure was gradually increased until it reached a rated pressure of 24 atm × 60 s × 2-times. If the high-pressure balloon still did not open completely, re-dilatation, such as with the parallel wire technique, could be chosen, or surgical revision was considered. Cutting balloons, drug-coated balloons, and stents were not used.

IVUS-Guided Peripheral Artery Recanalization

All patients underwent IVUS-guided percutaneous transluminal angioplasty (PTA). Conventional balloon dilatation catheters (Ultra-thin diamond or Mustang, Boston Scientific Japan, Tokyo, Japan) were used to enlarge stenotic vessels up to their rated balloon pressures if applicable.
VA surgery was performed when significant underlying vessel restenosis was refractory to recanalization even by repeatedly intensive conventional PTAs. The tissue specimens of exactly stenotic vessels were obtained from vascular surgeries in 3 out of 10 patients who had undergone repeated IVUS-VH analyses to reconstruct virtually histological composition of stenotic lesions.
The study was approved by the local ethical committee and was also in adherence with the Declaration of Helsinki.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
