We describe an uncommon case of acute coils migration with significant occlusion of M3 branch and our management of this complication. Ballon-assisted coil placement was performed for an unruptured intracavernous internal carotid artery aneurysm in a 62-year-old woman. After coil placement and balloon deflection, we observed coils migration with significant occlusion of M3 branch. After early clinical deterioration without other neurological symptoms, we decided to perform superficial temporal artery-middle cerebral artery (STA-MCA) bypass to ensure blood flow distal to the occlusion. The patient was discharged without neurological deficit. To the best of our knowledge, this is the first case report about STA-MCA bypass to treat acute coils migration. This technique could represent a successful rescue therapy in case of acute coils migration that cannot be retrieved by endovascular tools or in case where distal and deep location of migrated coils controindicate surgical removal.

Misshapen/NIKs-related kinase (MINK) 1 belongs to the mammalian germinal center kinase (GCK) family. It contains the N-terminal, conserved kinase domain, a coiled-coil region, a proline-rich region, and a GCK, C-terminal domain with the Citron-NIK-Homology (CNH) domain. The kinase is an essential component of cellular signaling pathways, which include Wnt signaling, JNK signaling, pathways engaging Ras proteins, the Hippo pathway, and STRIPAK complexes.

Rationale: Pseudoaneurysm is a potential postoperative complication in hepatobiliary and pancreatic surgery, with catheter-based interventions being the first-line treatment. This study reviews the literature on potential secondary complications following arterial embolization. Additionally, we report a case in which a dislodged embolization coil acted as a nidus for bile duct stone formation, leading to recurrent cholangitis.

Purpose: Intraprocedural complications during intracranial embolisation include thromboembolic vessel occlusion, catheter tip detachment and coil migration. Stentrievers and aspiration catheters are valuable devices for the management of these complications. We present our experience with the use of these devices.

A 21-year-old male with hereditary hemorrhagic telangiectasia underwent coil embolization for three pulmonary arteriovenous malformations (right Sc, right Sa, and left Sb). Three years after coil embolization, coil migration was observed in the right Sc and Sa, and a cavitary lesion developed between the two coils. Four years after embolization, the two coil lesions were found to have merged within the cavity.

We present an autopsy case of a child with Takayasu arteritis who succumbed due to cerebrovascular accident with an interesting finding in the inflamed aorta. On account of necro-inflammatory changes in the media of the distal descending thoracic aorta coupled with the shear stress of accelerated hypertension, there was a medial detachment, which migrated and lay between the intima and media of the abdominal aorta. This displacement was visualized on gross and histopathological examination as a 'laminated' appearance of coils of discontinuous inflamed tunica media, reminiscent of a hydatid cyst, which has been designated as medio-medial intussusceptions.
