Introduction There is an absence of widely accepted guidelines for the management of infectious intracranial aneurysms (IIAs) owing to a dearth of high-quality evidence in the literature. Objective To better define the incidence of IIAs, treatment practices, and patient outcomes by performing a Nationwide Inpatient Sample (NIS) database query. Methods We queried the NIS database from 2002 to 2011 for all patients with the primary diagnosis of infectious endocarditis (IE), subarachnoid hemorrhage (SAH), or unruptured cerebral aneurysm by ICD-9-CM codes. ICD-9 procedure codes were used to identify patients undergoing neurosurgical or cardiothoracic procedures. Results The query identified 393 patients with primary diagnosis of IE, SAH or unruptured cerebral aneurysm treated during 2002-2011. The mean age of the patients was 53.5 years; 244 (62%) were male. The majority of patients presented with SAH (361; 91.9%). Only 73 (18.6%) patients underwent neurosurgical coiling or clipping for IIA. Of patients undergoing a neurosurgical procedure, 65 had SAH (constituting only 18% of patients with SAH) and 8 had unruptured aneurysms (constituting only 25% patients with unruptured aneurysms). Cardiac procedures were performed in only 72/393 patients (18.3%) patients. Only 67 (18.6%) of the patients with SAH and 5 (15.6%) with unruptured aneurysms underwent a cardiac corrective surgical procedure. Mortality was significantly higher in those patients managed conservatively (26.7%) than in those who underwent clipping or embolization (15.1%; p<0.001). Conclusions In this NIS database study, the majority of patients with IIAs were managed non-operatively, regardless of rupture status. Further investigation is warranted to standardize the management of these lesions. [ABSTRACT FROM AUTHOR]

Current approaches to stratify the risk for disease progression in thoracic aortic aneurysm (TAA) lack precision, which hinders clinical decision making. Connective tissue phenotyping of children with TAA previously identified the association between skin striae and increased rate of aortic dilation. The objective of this study was to analyze associations between connective tissue abnormalities and clinical endpoints in adults with aortopathy. Participants with TAA or aortic dissection (TAD) and trileaflet aortic valve were enrolled from 2016 to 2019 in the setting of cardiothoracic surgical care. Data were ascertained by structured interviews with participants. The mean age among 241 cases was 61 ± 13 years. Eighty (33%) had history of TAD. While most participants lacked a formal syndromic diagnosis clinically, connective tissue abnormalities were identified in 113 (47%). This included 20% with abdominal hernia and 13% with skin striae in atypical location. In multivariate analysis, striae and hypertension were significantly associated with TAD. Striae were associated with younger age of TAD or prophylactic aortic surgery. Striae were more frequent in TAD cases than age- and sex-matched controls. Thus, systemic features of connective tissue dysfunction were prevalent in adults with aortopathy. The emerging nexus between striae and aortopathy severity creates opportunities for clinical stratification and basic research. [ABSTRACT FROM AUTHOR]
