“…In addition, coils should have been sized 20%-30% larger than the size of the vessel as measured on a pre-deployment angiogram to prevent distal embolization or migration, as the placement of an undersized coil risks its distal embolization away from the intended location (24). Koganemaru et al (27) reported that small-diameter primary coils and microcatheter tips that are thinner than normal can be used to increase the safety and reliability of coil embolization.…”

“…or smaller. [6][7][8][9] The triaxial system was previously shown to be useful for super-selective catheterization under various conditions. 5 In particular, it should be very effective for cases which definitely need super-selective catheterization, such as those with pseudoaneurysm, gastrointestinal bleeding, or type 2 endoleak after EVAR.…”

Background A triple-coaxial (triaxial) system, which consists of a small microcatheter, a large microcatheter, and a 4-Fr. catheter, has been reported to allow super-selective catheterization. A 1.6-Fr. microcatheter has recently become available as the small microcatheter for the triaxial system, in addition to 0.014-in. pushable bare platinum coils that may be introduced into the 1.6-Fr. microcatheter. Purpose The purpose of the present study was to evaluate the feasibility of 0.014-in. pushable bare platinum coils in embolization through the 1.6-Fr. microcatheter of the triaxial system. Material and Methods Between November 2015 and October 2019, 19 embolizations were performed on 18 patients, 9 males and 9 females with a median age of 77 years (range, 41–88 years), using 0.014-in. pushable bare platinum coils through the 1.6-Fr. microcatheter of the triaxial system. The technical success rate, clinical success rate, and complications associated with the procedure were assessed. Technical success was defined as the successful delivery and placement of 0.014-in. pushable bare platinum coils, and clinical success as the immediate postembolic complete cessation of blood flow confirmed by digital subtraction angiography. Results Eighty-four 0.014-in. pushable bare platinum coils were delivered and 19 arteries were successfully embolized. The median number of 0.014-in. pushable bare platinum coils was 4 (range, 1–12). The technical success rate was 100% (84/84) and the clinical success rate was also 100% (19/19). There were no complications associated with the procedures. Conclusion The use of 0.014-in. pushable bare platinum coils in super-selective embolization through the 1.6-Fr. microcatheter of the triaxial system appears to be feasible and safe.

“…Despite the identification of at least 20% of coil dense packing to reduce the risk of aneurysm recanalization [26]. In case of tight packing density with covered of long tracts of efferent and afferent artery to SAA, the acute exclusion of splenic circulation can potentially lead to splenic infarction [27][28][29]. The employed Concerto Helix Detachable Coil System (Medtronic, Inc.) are constructed of a platinum embolization coil linked to a pushable delivery system enclosed to the spiral.…”

Splenic artery aneurysm (SAA) management is various but endovascular solutions are preferred for a lower incidence of mortality and morbidity. The aim is to report SAA management using moderate packing of detachable coil embolization without routine splenectomy. From January 2015 to September 2022, we retrospectively analyzed patients presenting SAA and treated by moderate packing detachable coil embolization. SAA treatment indications were transverse diameter >2 cm, any size pseudoaneurysm, any size women in childbearing age and abdominal symptoms. The measured outcomes were technical success; mortality, morbidity, abdominal symptoms onset, and splenic infarction. Median follow-up was 34.77±9 months. Seven patients (median transverse diameter of 23±20 mm) were included. Technical success was achieved in all cases. No early mortality, abdominal pain onset or recurrence, reintervention, or splenic infarction was registered. Detachable coil moderate packing embolization is safe and effective for SAA management. The moderate coil packing maintained a limited splenic vascularization in the early period and avoided splenic infarction. During the follow-up, the coil embolization allowed SAA exclusion with no SAA growth. Larger patient samples with longer follow-up are required to validate this technique.
