“…Endobronchial coil migration as a long-term complication is rare, with only 13 reported cases (Table 2) (1,(9)(10)(11)(12)(13)(14)(15)(16)(17)(18). In 7 of the 13 patients, coil migration occurred more than a year after coil embolization, with a median period of 2.3 (1.2-12) years.…”

An 87-year-old woman who had undergone coil embolization 25 years ago for pulmonary arteriovenous fistula, which was diagnosed following repeated cerebral infarction, presented with massive hemoptysis. The coils migrated and were excreted in stool following hemoptysis during long-term follow-up. Although the technical success rate of coil embolization for pulmonary arteriovenous malformations is extremely high, and coil embolization-related complications are rare, little is known about the long-term complications. We herein report the clinical course of our case, review previous reports related to coil migration as a long-term complication, and discuss the associated mechanism.

“…Complications caused by coil migration after pulmonary embolization include fistulization, erosion into the bronchus, migration into the contralateral pulmonary vasculature, pulmonary hypertension, pneumothorax, and migration to the heart ( 9 ). The exact mechanism underlying coil migration remains unclear.…”

“…Coil embolisation has been widely used in AVMs achieving a technical success rate of 99%. Unfortunately, however, complications associated with coil embolisation include coil recanalisation, vascular damage and coil migration [102]. To overcome this problem, it is possible to use hydrogel-coated coils capable of increasing the packing density in the vascular lumen, ensuring better results and reducing the speed of recanalisation compared to bare coils.…”

This review focuses on the use of conventional gel or coil and “new” generation hydrogel used as an embolic agent in endovascular applications. In general, embolic agents have deep or multidistrict vascular penetration properties as they ensure complete occlusion of vessels by exploiting the patient’s coagulation system, which recognises them as substances foreign to the body, thus triggering the coagulation cascade. This is why they are widely used in the treatment of endovascular corrections (EV repair), arteriovenous malformations (AVM), endoleaks (E), visceral aneurysms or pseudo-aneurysms, and embolisation of pre-surgical or post-surgical (iatrogenic) lesions. Conventional gels such as Onyx or coils are now commercially available, both of which are frequently used in endovascular interventional procedures, as they are minimally invasive and have numerous advantages over conventional open repair (OR) surgery. Recently, these agents have been modified and optimised to develop new embolic substances in the form of hydrogels based on alginate, chitosan, fibroin and other polymers to ensure embolisation through phase transition phenomena. The main aim of this work was to expand on the data already known in the literature concerning the application of these devices in the endovascular field, focusing on the advantages, disadvantages and safety profiles of conventional and innovative embolic agents and also through some clinical cases reported. The clinical case series concerns the correction and exclusion of endoleak type I or type II appeared after an endovascular procedure of exclusion of aneurysmal abdominal aortic (EVAR) with a coil (coil penumbra released by a LANTERN microcatheter), the exclusion of renal arterial malformation (MAV) with a coil (penumbra coil released by a LANTERN microcatheter) and the correction of endoleak through the application of Onyx 18 in the arteries where sealing by the endoprosthesis was not guaranteed.

“…The common complications associated with coil embolization include coil recanalization, [84,85] vascular injury, [86] and coil migration. [87] These issues could be addressed by using hydrogel-coated coils to increase the packing density in the vascular lumen, which resulted in improved outcomes as well as lowering the recanalization rate compared to bare coils. [88,89] Liquid embolic agents permit a high and homogeneous packing of the vascular area and reduce the likelihood of recanalization.…”

Transcatheter arterial embolization, a minimally invasive treatment to deliberately occlude the blood vessels, has become a safe and effective procedure for the management of vascular diseases and benign/malignant tumors. Particularly, hydrogel‐based embolic agents have garnered much attention because of their potential to address some of the limitations of clinically used embolic agents and can be rationally designed to impart more favorable characteristics or functions. In this review, the recent progress toward the development of polymer‐based hydrogels for effective endovascular embolization, including the in situ gelling hydrogels mediated by physically or chemically crosslinking, imageable hydrogels for intraprocedural and postprocedural feedback, use of hydrogels as the drug depot for local delivery of therapeutic drugs, hemostatic hydrogels inducing extrinsic or intrinsic coagulation of blood, stimuli‐responsive shape memory hydrogels as the smart embolization devices, and hydrogels incorporating external‐stimuli functional materials for multidisciplinary therapy, is systemically summarized. Moreover, the potential considerations of hydrogel‐based embolic agents confronted in therapeutic embolization are pointed out. Finally, the perspectives for the development of more effective embolic hydrogels are also highlighted.
