Subarachnoid hemorrhage due to intradural cerebral aneurysm and simultaneous spinal subdural hematoma: illustrative case.

Background: Spontaneous spinal subdural hematomas (SSDHs) are unusual. Among their probable etiologies, an association with ruptured brain aneurysms has been described in an extraordinary way. The underlying pathophysiological mechanism is not conclusively described in the literature.

Fibrin-Platelet Clots in Acute Ischemic Stroke. Predictors and Clinical Significance in a Mechanical Thrombectomy Series.

The histological composition of the clot influences its mechanical properties, affects the efficacy of endovascular treatment (EVT), and could determine the clinical outcome of patients with acute ischemic stroke (AIS). Insights into clot composition may guide therapeutic decision-making prior to EVT and facilitate revascularization therapies. Consecutive patients with AIS recorded in a prospective single-center reperfusion registry from December 2015 to December 2019 and treated with EVT were included.

Comaneci device-assisted embolization of wide-necked carotid aneurysms with an unfavorable ratio.

Background: Endovascular treatment is the technique of choice for most intracranial aneurysms. However, the treatment of morphologically complex wide-necked aneurysms with an unfavorable anatomy is still a therapeutic challenge. The purpose of the study is to describe the initial experience with the Comaneci embolization assist device for the treatment of wide-necked aneurysms with an unfavorable ratio for direct embolization.

Endovascular management of an unsual case of spontaneous Retroperitoneal Haemorrhage due to Fibromuscular Dysplasia.

Background: Fibromuscular dysplasia (FMD) is an uncommon vascular disease that results in stenosis, dissection or aneurysmal degeneration. However, it can sometimes manifest atypically, as we show in this case.

Case Presentation: A 24-year old patient with no relevant medical history with severe left hypochondrium pain.

Simultaneous Angioplasty and Mechanical Thrombectomy in Tandem Carotid Occlusions. Incidence of Reocclusions and Prognostic Predictors.

Objectives: The best revascularization technique for tandem carotid occlusions is not clearly defined. The primary objective of this study is to describe our technical and clinical results, analyzing the main predictors of functional independence. The secondary objective is the analysis of stent reocclusion rate.

Histopathological and Bacteriological Analysis of Thrombus Material Extracted During Mechanical Thrombectomy in Acute Stroke Patients.

Purpose: Management of stroke secondary to septic emboli (SE) remains challenging, due to both the lack of specific recommendations and the gravity of the underlying pathology.The aim of this study is to describe the presence of SE in a series of mechanical thrombectomies (MT), analyzing technical complexity and outcomes with respect to the patients by means of histological analysis and microbiological study of the clot.

Methods: All the retrieved clots were studied under an established protocol, including histopathological and bacteriological study with hematoxylin-eosin, Gram and Gomori trichrome staining.
