Introduction: The objective of our study is to know the efficacy and safety of endovascular treatment in our setting.
Patients And Methods: a) prospective evaluation of patients with aneurysmal subarachnoid hemorrhage (SAH) or incidental aneurysm (Dec 1999-Dec 2002), and b) neurological, angiographic and evolutive evaluation of the endovascularly operated patients.
Results: A total of 79 patients were evaluated: 75 with SAH, 4 with incidental aneurysm. Arteriographies were performed in 74 (93.6%), detecting 58 aneurysms in 52 patients, 15 of the anterior communicating artery (25%) and 14 of the posterior communicating artery (24%). Fifty-two aneurysms were treated with Guglielmi Detachable Coiling (GDC) (89.6 %). Total occlusion (100 %) was obtained in 48 (82.7%) and partial occlusion in 4. Technique failure occurred in six cases. The earlier complications, after endovascular procedure (< 24 h), were one rebleeding, four angiographic spasms and ischemia and one coil displacement. During the first month, there were other cases of rebleeding and two cases of spasm and ischemia. Morbidity rate was 11.5 %. Death rate was 5.7 %. Follow-up period ranges between 6 and 42 months. After endovascular treatment 40 patients had a favourable outcome (Ranking 1-2) and 9 suffered moderate-severe incapacity (Ranking 3-5). We prescribed angiographic controls one year after the hemorrhagic event and there was only one case of aneurysmal recurrence.
Discussion: In our experience endovascular treatment is useful to treat ruptured and unruptured aneurysms, with similar surgical occlusion, morbidity and death rates.

Outcome of acute ischemic stroke with absent opacification of the cervical internal carotid artery at CT-angiography after endovascular treatment.

Occlusion of the distal internal carotid artery can simulate a proximal occlusion of its cervical tract on CT angiography in patients with acute ischemic stroke, that is, pseudo-occlusion. As true and false carotid occlusions can present similarly on non-invasive imaging in patients undergoing endovascular treatment for stroke, our study aimed to evaluate clinical and technical differences of these conditions and the possible consequences of a misdiagnosis. We retrospectively reviewed consecutive patients who underwent mechanical thrombectomy for acute ischemic stroke at a single center between July 2015 and May 2022 and included patients with absent opacification of the cervical carotid artery on CT-angiography.

This first-in-man (FIM) study evaluated the feasibility and safety of a new peripheral plaque atherectomy system in patients with symptomatic lower extremity artery disease (LEAD). Ten patients with symptomatic LEAD (Rutherford class 2-5) were enrolled in a prospective, single-center study from March to April 2024. Patients aged 18-85 years with target lesions showing ≥70% stenosis and reference vessel diameters ≥1.

Background: Contrast-associated acute kidney injury (CA-AKI) is frequent in patients with chronic kidney disease who are submitted to cardiac endovascular procedures using iodinated contrast. In hemoadsorption, cartridges containing styrene-divinylbenzene sorbent resin are applied to remove substances from the blood through an extracorporeal circuit. Importantly, iodinated contrast is also removed via adsorption.

Patients with intracranial aneurysm (IA) are at high risk of cerebral hemorrhage, which is associated with high mortality. Craniotomy or interventional endovascular coiling are common treatment methods in clinical practice, depending on the patient's condition. However, the recurrence rate of IA after either method remains unclear.

The e-STROKE study is a prospective, multicenter observational study designed to assess the impact of various CT parameters (including e-ASPECT, CT perfusion (CTP), collateral flow status, and the size and location of the ischemic lesion) on the clinical outcomes of patients with ischemic stroke, as evaluated by the modified Rankins Scale (mRS) three months post-stroke. This study also aims to investigate whether the use of multimodal CT imaging increases the number of patients eligible for recanalization therapy. The analysis will integrate data from the RES-Q registry and radiological data from the e-STROKE system provided by Brainomix Ltd.
