Using overlapping low-profile visualized intraluminal support stent-assisted coil embolization for treating blood blister-like aneurysms of the internal carotid artery

In this study, we attempted to discuss the key techniques for overlapping low-profile visualized intraluminal support (LVIS) stent-assisted coil embolization, which is used for treating BBAs in our center. Clinical characteristics, endovascular treatment details, outcomes, and follow-up results of 13 patients with BBA treated at our center were retrospectively evaluated in this study. Overlapping LVIS stent-assisted coil embolization was successfully performed in all 13 patients of ruptured BBAs located in the ICAs. Recurrence of aneurysm was observed in 4 cases (30.8%) during the angiographic follow-up; in 2 of these cases, spontaneous healing was observed after discontinuation of antiplatelet therapy. Further, 2 patients with recurrence underwent endovascular treatment with complete obliteration of the aneurysm in one and occlusion of the parent artery after Onyx embolization and stent placement in the other. The overall obliteration rate of the BBAs was 92.3% (12/13). One patient (7.7%) developed intraoperative rupture of the aneurysm with coils protruding outside; however, no severe hemorrhage or neurological dysfunction occurred owing to timely embolization. Overlapping LVIS stent-assisted coil embolization is effective for management of BBA of the ICA. Appropriate adjustment in antiplatelet therapy may improve healing in recurrent cases.

Conclusion: Our paper presents a rare contingency, warning the operator to bear in mind the presence of arteries feeding the spinal cord. This crucial detail precludes the use of microparticles embolisation to prevent neurologic sequelae, whereas the use of endovascular coils for embolization should be mandatory. Moreover, this case reminds that the post-traumatic bleeding deriving from a cervical trauma may also occur later. PMID: 32391083 [PubMed]

Conclusion: While the literature has shifted towards endovascular treatment for TICAs, surgery still offers a safe and efficacious treatment strategy especially when TICAs present at large vessel bifurcation points where parent vessel sacrifice and stent assisted coiling are less favorable strategies. Severe flow limiting vasospasm can be seen in post-traumatic setting specifically PBI. Vasospasm can be treated during open surgery with intracisternal papaverine and arterial soft dissection as confirmed in this case report with intraoperative micro-flow probe measurements.

Conclusion: Clipping and coiling were both safe and feasible in the treatment of unruptured aneurysms. The clipping was advantageous in durability, while the rate of morbidity was lower, and hospitalization period was shorter in the coiling group. The clipping and coiling should coexist while complementing each other by understanding the advantages and disadvantages of both. PMID: 32257576 [PubMed - as supplied by publisher]

Conclusion: Cerebral aneurysm coiling could be considered as the first choice of treatment in the case of acute MI with hemodynamic stability, before carrying out cardiac endovascular intervention or antiplatelet medication to reduce the risk of rebleeding from a brain aneurysm.

With advances in neurointerventional device technology and increased experience with aneurysm embolization, endovascular treatment (EVT) has become a widely accepted modality to treat intracranial aneurysms (IAs) [1]. During EVT of IAs, aneurysms are packed as densely as possible, which makes it exceedingly difficult to implant coils while ensuring safety and complete occlusion [2,3]. However, there appears to be a paradoxical challenge for small ruptured aneurysms (SRAs,

CONCLUSION: The double microcatheter technique for the treatment of wide-necked VRAAs appears to be relatively safe and useful. However, complex renal artery aneurysm should be carefully managed in order to prevent infarction. PMID: 32209509 [PubMed - as supplied by publisher]
