A 28-year-old man with a history of coil embolization of multiple pulmonary arteriovenous malformations presented with hemoptysis 11 years after initial embolization. A cavity lesion in the left upper lobe, which was accompanied by deformed coils and ground-glass opacity, was considered responsible for hemoptysis. Embolization of the bronchial artery was performed.

Background The objective of this study was to present the long-term safety and effectiveness of strand remodelling with a hypercompliant balloon. Methods Patients with complex wide-neck bifurcation aneurysms (WNBAs) who underwent strand remodelling with a hypercompliant balloon via Y-stent-assisted coil embolization (Y-SACE) between September 2016 and January 2020 were included in the study. The feasibility, safety, effectiveness, and complication rates of the strand remodelling technique were investigated. Results A total of 12 patients (6 females, 6 males) were included in this study. Significant expansion was obtained in the intersection zone after remodelling. No regression was observed in the expansion rates during follow-up. There was no additional morbidity or mortality. No delayed thromboembolic complications occurred in our patients during long-term follow-up. Conclusions Performing strand remodelling to reduce thromboembolic complications triggered by structural faults caused by the Y-stent configuration is feasible, safe, and effective. This new approach can aid in the prevention of thromboembolic complications in Y-SACE.

We evaluated long-term angiographical follow-up of cerebral aneurysms treated with detachable platinum coils with special reference to the long-term morphological outcomes of incompletely obliterated aneurysms. Serial long-term follow-up cerebral angiograms (>1 year) were obtained in 47 cases out of 134 cases treated with GDCs or IDCs from 1994 to 1999. In 47 patients, intial angiographical results demonstrated ten complete aneurysmal occlusion, seven aneurysms with a small neck remnant, twenty aneurysms with body filling and ten aneurysms with both of neck remnant and body filling. In the ten completely obliterated aneurysms, follow-up angiograms revealed no aneurysmal recanalization. In seven aneurysms with neck remnant, three remained unchanged, four showed enlargement of contrast filling in the part of the neck of the aneurysm. In twenty aneurysms with body filling, five had developed into complete obliteration, three remained unchanged, 11 had recanalization, and one aneurysm displayed regrowth. In ten aneurysms with both of neck remnant and body filling, two remained unchanged, five had recanalization, and three aneurysms displayed regrowth. Long-term angiographical follow-up results are less satisfactory in cases involving incompletely obliterated lesions. A higher incidence of recanalizations were promoted in cases with neck remnant and/or body filling. Strict follow-up angiography is mandatory when a complete obliteration is not achieved.

OBJECTIVELong-term follow-up results of the treatment of unruptured intracranial aneurysms (UIAs) by means of coil embolization remain unclear. The aim of this study was to analyze the frequency of rupture, retreatment, stroke, and death in patients with coiled UIAs who were followed for up to 20 years at multiple stroke centers.METHODSThe authors retrospectively analyzed data from cases in which patients underwent coil embolization between 1995 and 2004 at 4 stroke centers. In collecting the late (≥ 1 year) follow-up data, postal questionnaires were used to assess whether patients had experienced rupture or retreatment of a coiled aneurysm or any stroke or had died.RESULTSOverall, 184 patients with 188 UIAs were included. The median follow-up period was 12 years (interquartile range 11–13 years, maximum 20 years). A total of 152 UIAs (81%) were followed for more than 10 years. The incidence of rupture was 2 in 2122 aneurysm-years (annual rupture rate 0.09%). Nine of the 188 patients with coiled UIAs (4.8%) underwent additional treatment. In 5 of these 9 cases, the first retreatment was performed more than 5 years after the initial treatment. Large aneurysms were significantly more likely to require retreatment. Nine strokes occurred over the 2122 aneurysm-years. Seventeen patients died in this cohort.CONCLUSIONSThis study demonstrates a low risk of rupture of coiled UIAs with long-term follow-up periods of up to 20 years. This suggests that coiling of UIAs could prevent rupture for a long period of time. However, large aneurysms might need to be followed for a longer time.

Arteriovenous malformation (AVM)-related aneurysms have been described in the literature. Their behavior varies based on their location in relation to and the activity of the shunting through the index AVM. The intuitive expectation supported by numerous reports is that these aneurysms should regress if the AVM is excluded from the circulation. We describe a case of 46-year-old man who presented with a posterior fossa AVM with an aneurysm on the posterior inferior cerebellar artery feeding the AVM. The nidus of the AVM was successfully excluded by glue embolization, with initial regression of the PICA aneurysm on serial imaging. Five years after the endovascular treatment, the aneurysm showed significant re-growth necessitating endovascular coiling. This case presents the re-growth of an AVM-related aneurysm and emphasizes the importance of long-term follow-up of such aneurysms even if the AVM is completely excluded.
