Radial Artery Access Technique for Coronary Angiography

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

The access site was anaesthetized with lidocaine and then right radial arterial access was taken using a 6F radial sheath (Radifocus introducer II, Terumo, Japan). To reduce vasospasm and forearm discomfort, pre prepared mixture containing Nitroglycerine 100 μg, Diltiazem 5 mg and Lidocaine 21.3 mg was administered through the radial sheath. Unfractionated heparin was administered in all patients in doses of 100 units/kg.
Coronary angiograms were performed with 5 French (5F) diagnostic catheters (Optitorque, Terumo, Japan) followed by angioplasty using 6F standard coronary guiding catheters (Launcher, Medtronic Inc., Minneapolis, USA). Immediately after the procedure, the radial artery sheath was removed and haemaostasis was achieved by the application of haemaostasis device (TR band, Terumo, Japan) using patent haemaostasis technique.¹⁷ Procedural details like catheter exchanges, angiographic severity of coronary artery disease, number of vessels stented, total number of stents used in each patient, procedure time and radiation dose were noted for each patient.

Comprehensive Gallbladder Stone Removal

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

One week after PTBD, contrast was injected through the CBD catheter to perform cholangiography, identifying the anatomic characteristics of the bile duct tree and if there was any residual CBD stones. If yes, PTBD was performed again. If no, a guide wire and a 4-Fr single-angle catheter (Terumo Medical Corporation, Tokyo, Japan) were introduced through the previous transhepatic tract into the gallbladder through the cystic duct in sequence. Cholangiography revealed the number, size, and location of the gallbladder stones (Figure 4A). Large stones were extracted to the CBD with a basket (Olympus, Japan) and then pushed into the duodenum using PTBD (Figure 4B). Sandy stones could be aspirated through a guiding catheter (Launcher, Medtronic, Minneapolis, MN, United States) (Figure 4C). An 8.5-Fr drainage catheter was placed in the gallbladder and removed after two weeks without residual stones.

Retroinjection in Cardiac Venous System

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

An 8F introducer sheath was placed in the femoral vein and a shortened 7F guiding catheter with large inner diameter (Launcher, Medtronic) was advanced to the ostium of the great cardiac vein, the most prominent vein of the LV lateral wall (LVLW) or the MCV. With the support of the guiding catheter and a hydrophilic 0.032″, 0.025″ or 0.018″ guidewire, a 4-6F wedge pressure balloon catheter was advanced selectively one by one into the three main veins of the LV for the retroinjection procedure.
In the fourth set of experiments, a 2.5F microcatheter was inserted into the apical part of the ACV through the 6F wedge pressure balloon catheter, using the standard 0.014″ guidewire. For occluding the main venous anastomosis, a 4-5F wedge pressure balloon catheter was inserted into the main anastomotic vein of the target vein via a 7F guiding catheter (Launcer, Medtronic) and an 8F introducer sheath placed in the external jugular vein.

Endovascular Treatment for Portal Venous Thrombosis

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

An 8-Fr sheath (Supersheath; Medikit, Tokyo, Japan) was inserted into the portal venous system via the transhepatic or transileocolic route, and heparin was administered to maintain the activated clotting time within the range of 200–300 s during temporary EVT sessions. A 6-Fr catheter (Aspiraircass; Medikit) and an 8-Fr guiding catheter (Launcher; Medtronic, Dublin, Ireland) were used for manual AT. A one-shot injection of the thrombolytic agent was administered using urokinase (Mochida, Tokyo, Japan) via a 5-Fr multiple-side-hole infusion catheter (Fountain Infusion System; Merit Medical, South Jordan, UT, USA). POBA was performed for fragmentation of the thrombus and crimping the thrombus to the vessel wall. Bare metal stents (WALLSTENT; Boston Scientific, Marlborough, MA, US. E-LUMINEXX; BD, Tokyo, Japan) were used in cases with mechanical stenosis or thrombi refractory to AT, POBA, and CDT. Most cases were initiated with AT to remove the thrombus as much as possible. CDT and POBA were performed for residual thrombi refractory to AT. Primary stenting was performed in cases of mechanical stenosis and thrombus confined to the main trunk of the PV and SMV. The continuous CDT session was initialized when recanalization of PV and SMV was not achieved.

Radial Access Angiography and Angioplasty

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

The RA was cannulated using a through-and-through puncture technique, and only 6Fr hydrophilic 10-cm-long sheaths (Radiofocus Introducer II, Terumo, Japan) were used. After sheath insertion, a radial cocktail containing 5 mg of verapamil and heparin 3000 U diluted in a 10-ml syringe was injected gradually through the sheath side arm into the RA. Coronary angiography was preferentially performed using a single diagnostic universal 5Fr Tiger catheter (Terumo, Japan), although standard 5Fr Judkins diagnostic coronary catheters (Cordis, USA) could also be used. Angioplasty was performed with 6F guiding catheters (Launcher, Medtronic, Inc., USA) under full heparinization (add up to 10,000 U). Hemostasis was achieved by immediate postprocedural sheath removal and simple gauze and elastic bandage are used for 2–4 h, during which patients were advised to restrict movements of the wrist joint.

Transcatheter Arterial Duct Stenting

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

Procedures were done under general anesthesia. The approach was based on the orientation of the duct and was predominantly from the right axillary artery. A 5F sheath was inserted in the artery. A 4F Judkins right coronary diagnostic catheter (Cooks medical, Bloomington, USA) was used for cannulation of the duct. Selective hand injections of contrast were performed to profile the duct and BPAs in left anterior oblique view with cranial tilt or right anterior oblique view based on the anatomy and course of the arterial duct (Fig. 1A). The duct was crossed using an 0.014″ coronary guide wire, Runthrough (Terumo Medical Inc. Somerset, NJ) or Whisper extra support (Abbott laboratories, Santa Clara, CA). The wire was advanced as distally as possible into non-stenosed pulmonary artery. Then a 5F Judkins right coronary guide catheter, either Launcher (Medtronic, Minnesota, USA) or Cordis (Cordis Medicals, Santa Clara, CA) was exchanged to deliver the stent.

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.
