Cerebral DSA was performed via the transfemoral arterial approach using a dedicated biplane neuroangiography unit (RF-1000-125, Artis Zee biplane, Siemens Healthineer, Berlin, Germany) with the help of 1 type of guidewire (Terumo®, 0.035 inch, Tokyo, Japan) and 3 types of catheters—Taper (Cook, Bloomington, IN, USA), Imager (Boston Scientific, Marlborough, MA, USA), Simmons I (AngioDynamics, Queensbury, NY, USA). A non-ionic contrast medium (lomeron 300 [iomeprol 612.4 mg/mL], Bracco S.p.A., Milan, Italy) was used for all procedures with automatic machine injection of the contrast medium followed by a saline flush after each injection. The FemoSeal®, vascular closure device, was used for hemostasis at the site of vascular access. All procedures in this series were performed by a single neurovascular surgeon (the author of this study).
Imager
Manufactured by Boston Scientific
Sourced in United States
The Imager is a laboratory equipment product designed for image capture and analysis. It serves as a versatile tool for researchers and scientists, enabling them to capture high-quality images of various samples or specimens. The core function of the Imager is to provide a reliable and efficient means of acquiring visual data for further analysis and study.

The SAE procedure was performed 6–8 h before OS by an interventional radiologist with ten years of experience in SAE using the following technique: the femoral artery was punctured and a 5-F introducer sheath was placed; the splenic artery was catheterised under fluoroscopy using a 4- or 5-F cobra catheter (Imager, Boston Scientific, USA). We used a microcatheter (Renegade HI-FLO microcatheter, Boston Scientific, USA) in five patients with a tortuous splenic artery. The microcatheter was advanced through the cobra catheter till the splenic hilum. After securing the left gastroepiploic artery to preserve distal pancreatic branches of the splenic artery, infusion of polyvinyl alcohol particles (300–355 μm in diameter) (Contour Emboli, Boston Scientific Cork Ltd., Ireland) mixed with 25 mL of iodinated contrast and one ampule of gentamycin (80 mg) was done. The embolisation procedure was considered satisfactory when at least 60–70% of the parenchymal vascularity appeared as occluded at subjective assessment (Fig. 1 ). The procedure was performed using an angiography unit (Cath Lab System, Siemens, Artis Zee Ceiling VC21C). The average duration of the procedure was 20 min.![]()

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.
