Angiographic and epidemiological characteristics associated with aneurysm remnants after microsurgical clipping.

This study was conducted from February 2009 to August 2012 on a series of 90 patients with 105 aneurysms referred to the Santa Casa of Belo Horizonte who were surgically treated and angiographically controlled. RESULTS: Surgical clipping was considered incomplete in 13.3% of the aneurysms. The mean age of cases with an aneurysm remnant was 57.5 years, whereas the mean age without aneurysm remnant was 49.7 years (P = 0.02). Aneurysm remnants were detected more frequently on the internal carotid artery, nevertheless, no statistically significant differences were verified when comparing the locations. Aneurysm size in the preoperative angiography verified that the mean size of aneurysms operated was 6.56 mm, such that in cases showing a postoperative remnant, the mean size was 9.7 mm and in cases with complete clipping it was 6.08 mm (P = 0.02). Postoperative angiography showed that, in cases with residual aneurysm, the number of clips used was higher - a mean of 1.8 for complete clipping and 3.1 for incomplete clipping (P

CONCLUSIONS: our experience suggests that in a selected population of patients with challenging anatomy outside the IFU for conventional endograft, EVAR by Ovation stent-graft can be safely performed with satisfactory immediate outcomes. PMID: 31793884 [PubMed - as supplied by publisher]

CONCLUSIONS: Despite the greater inherent complexity, procedural and long-term clinical outcomes following PCI of distal LM trifurcations with everolimus-eluting stents in a modest-sized cohort from the EXCEL trial were similar compared with treatment of distal LM bifurcation disease without trifurcations. These findings support PCI as a treatment strategy for selected patients with distal LM trifurcation disease. PMID: 31793882 [PubMed - as supplied by publisher]

ConclusionBaseline cut off thrombus appearance predicts a  higher number of thrombectomy maneuvers. In day to day practice this may prepare the neurointerventionalist for a more challenging endovascular procedure ahead. Stroke etiology, clinical outcomes and thrombus-specific characteristics did not show any associations with the thrombus appearance.

This study assessed the efficacy of a pro-thrombotic VTA targeting phosphatidylserine (PS) in a radiation-primed AVM animal model. The model AVM was surgically created in rats by anastomosis of the left external jugular vein to the adjacent common carotid artery. After 6  weeks, the AVM was irradiated (20 Gy) using gamma knife surgery (GKS). A PS-targeting VTA was created by conjugation of annexin V with human thrombin and administered intravenously 3 weeks post-GKS or sham. Unconjugated thrombin was used as a non-targeting control. AVM thrombosis and occlusion w as monitored 3 weeks later by angiograph...

Computed tomography angiography derived global longitudinal strain (CTA-GLS) has been shown to be feasible, however its prognostic value remains unclear in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). We evaluated the association of baseline CTA-GLS with outcomes including all-cause mortality and composite endpoint of death and heart failure hospitalization in 223 patients treated with TAVR. Patients with normal LVEF but reduced CTA-GLS had similar event rate to those with impaired LVEF, and higher than those with normal LVEF and preserved CTA-GLS. Baseline CTA-GLS assessme...
