Endovascular Treatment of Acute Basilar Artery Occlusion: Registro Endovascolare Lombardo Occlusione Basilar Artery (RELOBA) Study Group Experience.

BACKGROUND: Acute basilar artery occlusion (BAO) is considered among the most severe medical emergencies, with very high morbidity and mortality. The aims of this study are to present 5 years experience of 12 centers in Lombardy region on BAO endovascular treatment and to evaluate prognostic factors that may improve clinical outcomes and recanalization rates. MATERIALS AND METHODS: Registro Endovascolare Lombardo Occlusione Basilar Artery (RELOBA) registry is a retrospective multicentric collection of patients with acute BAO who underwent endovascular treatment between 2010 and 2015. A total of 102 patients (mean age 65 years) were included. Clinical, procedural, and neuroradiological data were collected. Angiographic results (Treatment in Cerebral Ischemia scale [TICI] score 2b-3) were assessed by each center's interventional neuroradiologist. Good clinical outcome was considered as a modified Rankin Scale score ranging between 0 and 2 in a 3-month follow-up. RESULTS: Thirty-nine percent of patients showed good clinical outcome at 3 months. Mortality rate was 30%. TICI 2b-3 was achieved in 62% of patients. Univariate analysis showed that age, National Institutes of Health Stroke Scale (NIHSS) at onset, time to recanalization, and TICI score were all statistically significant clinical outcome predictors (P < .05). Multivariate logistic regression showed that time to recanalization, age, and NIHSS at onset were significant independent predictors of good outcome. CONCLUSIONS: BAO treatment needs more efforts to assure patients better clinical outcomes. Mechanical thrombectomy is feasible and effective in patients with acute BAO. These results must be confirmed by further prospective studies within randomized controlled settings.

Pituitary gland metastasis from rectal cancer: report of a case and literature review.

Pituitary metastases are unusual complications of malignancies. In about only 2% of patients they origin from colorectal cancer (CRC), with breast and lung as the most common primary tumors. Nevertheless, some authors reported a recent increase of the incidence of metastases in infrequent sites, such as brain or bone, arising from gastrointestinal cancers, probably due to the expanded treatment options and the resulting improved survival. Here, we report the case of a 54-year old woman diagnosed with lung metastases from rectal cancer, who, after several cycles of radio- and chemotherapy, presented symptoms and signs of pituitary disfunction (i.e. diabetes insipidus, hypothyroidism and diplopy). The diagnosis of pituitary metastasis from rectal cancer was histologically confirmed after surgery.

Subependymal periventricular heterotopias in a patient with ehlers-danlos syndrome: a new case.

Ehlers-Danlos syndrome is a complex hereditary connective tissue disorder that is characterized by abnormalities of the skin and joints and visceral and neurological manifestations. At present, at least 11 forms are recognized on the basis of their clinical characteristics, methods of transmission, and biochemical defect. The neurologic manifestations include cerebrovascular disease, peripheral neuropathy, plexopathy, periventricular subependymal heterotopias, and epilepsy. Previously, 2 females were reported to be affected with subependimal periventricular heterotopias and Ehlers-Danlos syndrome type 1. The authors report a new case of a 12-year-old girl with similar clinical and neuroradiological features.

Alpha-1-antitrypsin deficiency-associated cervical artery dissection: report of three cases.

The pathogenesis of cervical artery dissection is poorly understood. Deficiency of the elastase inhibitor alpha-1-antitrypsin may represent a predisposing condition. Biochemical and genetic analyses in a series of 12 consecutive patients with spontaneous dissection of the neck vessels showed 3 cases associated to alpha-1-antitrypsin deficiency, in combination with transient precipitating factors. A disequilibrium between proteolytic enzymes and protease inhibitors may contribute to the pathogenesis of cervical artery dissection leading to structural abnormalities of the extracellular matrix and increasing the susceptibility of the vessel wall to additional short-lived trigger mechanisms.
