ABSTRACT
BACKGROUND: Silent infarction in the brain can be detected in around 34 per cent of patients after carotid endarterectomy (CEA) and 54 per cent after carotid angioplasty and stenting (CAS). This study compared the risk of new infarctions in the brain in patients undergoing CEA or CAS. METHODS: Consecutive patients with internal carotid artery (ICA) stenosis exceeding 70 per cent were screened for inclusion in this prospective study. Patients with indications for intervention, and eligible for both methods, were allocated randomly to CEA or CAS. Neurological examination, cognitive function tests and MRI of the brain were undertaken before and 24 h after intervention. RESULTS: Of 150 randomized patients, 73 (47 men; mean age 64·9(7·1) years) underwent CEA and 77 (58 men; 66·4(7·5) years) had CAS. New infarctions on MRI were found more frequently after CAS (49 versus 25 per cent; P = 0·002). Lesion volume was also significantly greater after CAS (P = 0·010). Multiple logistic regression analyses identified intervention in the right ICA as the only independent predictor of brain infarction (odds ratio 2·10, 95 per cent c.i. 1·03 to 4·25; P = 0·040). Stroke or transient ischaemic attack occurred in one patient after CEA and in two after CAS. No significant differences were found in cognitive test results between the groups. CONCLUSION: These data confirm a higher risk of silent infarction in the brain on MRI after CAS in comparison with CEA, but without measurable change in cognitive function.

The surgical correction of ruptured intracranial infectious pseudoaneurysms is associated with high morbidity and mortality. An endovascular therapeutic approach has been introduced recently. This treatment is, compared to surgical intervention, less invasive, faster, more effective and safer, thus making it a gentler option, particularly for pediatric patients. Lower morbidity and mortality have been achieved thanks to the combination of prolonged administration of antibiotics, coil embolization, and parent artery occlusion. Two pediatric cases of bleeding mycotic pseudoaneurysm treated successfully with fibered coil embolization and long-term antibiotics are dealt with in this manuscript.

SUMMARY: A fusiform aneurysm in the terminal M1 middle cerebral artery (MCA) segment was treated by a construction of a high-flow arterial extracranial-intracranial (EC-IC) bypass. Due to severe bypass vasospasms, local vasodilating agents together with percutaneous angioplasty and stent implantation were applied, but failed due to subsequent bypass occlusion. To remedy this complication a new bypass was created from a segment of the saphenous vein, followed by MCA aneurysm embolization and parent artery occlusion. One year after the surgery, the venous bypass remains patent and the aneurysm occluded, with the patient fully active, without any neurological sequelae.
ABSTRACT
SUMMARY: We report on a case of a 14-year-old boy with a giant serpentine aneurysm of the left internal carotid artery cavernous segment with symptoms of acute mass-effect cranial nerve dysfunction. After a balloon occlusion test of the collateral circulation, the patient underwent parent artery occlusion with platinum Guglielmi detachable coils and fibered coils. An optimal angiographic result and successful clinical outcome were achieved with resolution of IIIrd, IVth and VIth cranial nerve ischemic symptoms. CT angiography and 3D-XRA rotational angiography reconstructions gave sufficient inclusion information on the giant serpentine aneurysm angioarchitechture.
ABSTRACT
SUMMARY: PHACE(S) syndrome is an acronym for neurocutaneous disease encompassing the expression of (P) posterior cranial fossa malformations, (H) facial haemangiomas, (A) arterial anomalies, (C) aortic coarctaion and other cardiac defects, (E) eye abnormalities and (S) for sternal malformation or stenotic arterial diseases. We report on a case of PHACE syndrome complete expression with persistent fetal vascular anomalies unusually in a 55-year-old women with large bilateral facial and neck haemangioma and posterior fossa circulation insufficiency.
