Intra-caval Net for Thrombus Capture

Check if the same lab product or an alternative is used in the 5 most similar protocols
After venography, a 0.035-inch guidewire (Terumo) was kept in the IVC through the sheath. The abdomen was incised at midline, and the IVC carefully exposed and isolated. The previously placed guidewire served as a marker of IVC, as it could be detected by fluoroscopy or felt by hand. Two vessel clips were then used to temporarily block the IVC bloodstream. One clip was placed on the IVC just below the renal veins and the other on the IVC just proximal to the bifurcation of the common iliac veins.
Next, four 4-0 polypropylene sutures (PROLENE™; Ethicon, USA) with a needle were used to pass through the IVC (2 cm below the renal veins) individually at anterior-posterior, transverse, and oblique directions (Fig. 6A). The intra-caval net was then made, consisting of four sutures intercrossed at the centre of the IVC lumen (Fig. 6B). Each suture was tied end-to-end at the outside wall of IVC. The net was used to capture the downstream thrombus. The vessel clips were finally removed and repeated venography was performed to inspect the IVC. The abdomen was closed, and the skin was sutured with 4-0 silk.

Before the procedure, the New Zealand rabbits were anesthetized via intramuscular injection. The animals were placed in a supine position with the neck hyperextended under fluoroscopic guidance (Artis zee DSA system, SIEMENS, Germany). The whole process was completed through a 5-Fr stent delivery system. A 12-Fr dilator (12-F dilator, Cook Medical) was used to dilate the entrance. Then, an intratracheal channel was created with a 0.035-inch guidewire (Terumo Corporation, Tokyo, Japan) and 5-Fr catheter (Terumo Corporation, Tokyo, Japan). The delivery system was pushed with the stent over the guidewire, and the stent was released at least 1.5–2 cm cranially to the carina (as shown in Fig. 6a). The animals were then clinically monitored and sacrificed 4 weeks after stenting.

Ureteroscopic Laser Lithotripsy Procedure

Check if the same lab product or an alternative is used in the 5 most similar protocols
After spinal or general anesthesia, all URSL procedures was performed in the lithotomy position using an 8/9.5 F semi-rigid ureteroscope (Karl Storz, Tuttlingen, Germany), a holmium laser lithotripsy system (Lumenis, Santa Clara, Amercia) and a pressure-controlled irrigation pump (JingRui, Zhejiang, China). Before lithotripsy, a 0.035-inch guidewire (Terumo, Shizuoka, Japan) was employed to attempt to pass through the stone by a semi-rigid ureteroscope. If guidewire failed to pass the stone, URSL was firstly conducted for space creation between the stone and the ureteral wall. The stones were fragmented using holmium laser lithotripsy after guidewire placed in the ureter. If patients were diagnosed as proximal impacted ureteral stone, after space creating, a ureteral occlusion device was utilized for the prevention of stone migration before continuing stone fragmentation. A double J stent (size 4.7 F of 6 F) was inserted in ureter at the end of procedure. Four weeks after surgery, the stent was removed and abdominal x-ray film was taken to detect the stone-free status in the follow up evaluation. All procedures were finished by the same experienced endourologist.

Ultrasound-Guided Percutaneous Transluminal Angioplasty

Check if the same lab product or an alternative is used in the 5 most similar protocols
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.

Four endovascular trained surgeons evaluated the model and performed the endovascular procedures in the circulation model. An introduction sheet was inserted proximal and the thrombotic occlusion was passed via a 0.035 inch guide wire (Terumo GmbH Germany, Eschborn, Germany) in order to perform simple aspiration thrombectomy, stent-implantation (Abbott, Chicago, USA; Absolut Pro Vascular self-expanding stent, 6 × 40 mm) and thrombectomy via Fogarty catheter (Edwards Lifesciences, Irvine, USA; Over-the-wire Fogarty catheter). Afterwards all interventionalists answered the SUS questionnaire and evaluated the handling of the model.

In the case of non-thrombotic occlusion, the distal end of the occluded venous segment was selected as the puncture site. Under ultrasound guidance, an 18 G (64 mm length) puncture needle (TERUMO, Tokyo, Japan) was employed to perforate the vein. The needle was introduced into the subcutaneous tissue following the pre-planned direction and angle (Figure 1(B)). Subsequently, a 0.035-inch guidewire (TERUMO, Tokyo, Japan) and a 6 F vascular sheath were inserted, with the sheath advanced over the guidewire to access the intended vessel (Figure 1(C)). Ultrasound reassessment ensured that the percutaneous tunnel was supported by the sheath.

cTACE was performed according to our standard institutional protocol, and all procedures were performed by an interventional radiologist (XYZ) with 15 years of experience in hepatic interventions. With use of the Seldinger's technique, a 5-F vascular sheath was placed in the right common femoral artery over a 0.035-inch guide wire (Terumo Medical, Somerset, NJ). Under fluoroscopic guidance, a 5-F glide Simmons-1 catheter (Cordis, Miami, FL) was advanced into the aortic arch and then used to select the celiac axis. The catheter was advanced into the desired hepatic artery over the guide wire. Using a 3-F Renegade High-Flo catheter coaxially over a 0.014-inch Transcend wire (Boston Scientific, Natick, MA), selective catheterization was performed to achieve lobar or segmental chemoembolization. A solution containing 50 mg doxorubicin (Adriamycin; Pharmacia &Upjohn, Peapack, NJ), and 10 mg mitomycin C in a 1:1 mixture with Lipiodol (Lipiodol; Guerbet, Paris, France) was infused and followed by the infusion of gelatin-coated trisacryl microspheres (Embosphere particles; Biosphere Medical, Rockland, MA) until arterial inflow was retarded as seen on fluoroscopy.

Check if the same lab product or an alternative is used in the 5 most similar protocols
The procedure was implemented under local anesthesia, accessing either through the right femoral or the left subclavian artery. Utilizing the Seldinger technique, a catheter was introduced into the arterial lumen over a 0.035-inch guidewire (Terumo, Tokyo, Japan). Angiography was performed on celiac, superior mesenteric, and extrahepatic arteries that fed the tumor, if present, to assess the anatomy of the hepatic blood supply and tumor arteries. Before HAIC port implantation, collateral branches from extrahepatic arteries were occluded to enhance treatment efficacy. Microcoils (Tornado, Cook, USA) were used to embolize the right gastric artery to prevent chemotherapeutic agents from refluxing into the stomach. A 5 Fr port and catheter (Celsite, B. Braun Medical, Pennsylvania, USA) were placed in the common hepatic artery before the distal end of the catheter was fixed to the gastroduodenal artery using Microcoils. After each cycle of HAIC therapy, 3,000–5,000 U of heparin were injected into the port to prevent catheter occlusion (17 (link)).
