“…Yamauchi et al 7 reported the use of subcutaneous infiltration of epinephrine-containing lidocaine to control the blood flow from the STA during TAE of dural arteriovenous fistulas. Omura et al 12 reported a damp-and-push technique for embolization of dural arteriovenous fistulas while preserving cutaneous vessels. In this method, liquid embolic material is injected from a major feeder while occluding a high-flow feeder with a balloon microcatheter.…”

BACKGROUND In meningiomas that occur in the high-convexity region, the superficial temporal artery (STA) frequently feeds the tumor, and when embolizing from the middle meningeal artery (MMA), the embolic material may not reach the tumor vessels because of the pressure gradient resulting from the STA blood flow, resulting in inadequate embolization. In this case, a circular plastic material was used to apply circumferential pressure around the parietal foramen to control blood flow to the tumor. OBSERVATIONS A 45-year-old male underwent head magnetic resonance imaging that revealed a 2.2-cm meningioma in the right high-convexity region. Preoperative embolization was performed. When N-butyl-2-cyanoacrylate was injected from the right MMA while using a circular plastic material to compress the skin around the parietal foramen through which the bilateral STAs (the tumor feeders) flow, it was able to fully penetrate the tumor vessel and occlude the other feeders in a retrograde manner. The patient underwent tumor removal after embolization uneventfully. LESSONS Manual compression of the STA using a circular plastic material is useful when the tumor is fed by the STA through the parietal foramen and is also applicable to transarterial embolization of dural arteriovenous fistulas fed by the STA or occipital artery.

Background This study aimed to assess the effectiveness and versatility of an intentional early detachment technique with detachable coils to address challenging vascular embolization scenarios. This novel approach aims to provide interventional radiologists with an alternative method for achieving precise coil placement when standard methods of detachable coil placement are rendered ineffective owing to vascular anatomy or limited available equipment. Materials and Methods This was a retrospective study comprising 11 patients (9 males and 2 females; median age, 77 years) who underwent embolization procedures using the intentional early detachment technique via 1.6-Fr or 1.3-Fr microcatheters between October 2021 and December 2023. In this technique, detachable coils were intentionally detached within the microcatheter and placed using saline flushing. Technical success, complications, and clinical success were evaluated. Results The technique was applied in three distinct scenarios: tortuous vascular anatomy (4 cases), inadequate system backup (3 cases), and 1.3-Fr microcatheter use (4 cases). The technical and clinical success rates were 100%. No complications were observed, and there were no cases of coil migration or malpositioning. Conclusion The intentional early detachment technique is valuable for interventional radiologists and offers a solution for challenging vascular embolization scenarios. Although its application is limited to specific circumstances, it can significantly enhance coil placement in complex cases, thereby contributing to improved patient care.
