Limb salvage prediction in peripheral artery disease patients using angiographic computer vision.

Background: Peripheral artery disease (PAD) outcomes often rely on the expertise of individual vascular units, introducing potential subjectivity into disease staging. This retrospective, multicenter cohort study aimed to demonstrate the ability of artificial intelligence (AI) to provide disease staging based on inter-institutional expertise by predicting limb outcomes in post-interventional pedal angiograms of PAD patients, specifically in comparison to the inframalleolar modifier in the Global Limb Anatomic Staging System (IM GLASS).

Methods: We used computer vision (CV) based on the MobileNetV2 model, implemented via TensorFlow.

Classification of anatomic patterns of peripheral artery disease with automated machine learning (AutoML).

Aim: The aim of this study was to investigate the potential of novel automated machine learning (AutoML) in vascular medicine by developing a discriminative artificial intelligence (AI) model for the classification of anatomical patterns of peripheral artery disease (PAD).

Material And Methods: Random open-source angiograms of lower limbs were collected using a web-indexed search. An experienced researcher in vascular medicine labelled the angiograms according to the most applicable grade of femoropopliteal disease in the Global Limb Anatomic Staging System (GLASS).

Stroke rate after thoracic endovascular aortic repair using de-airing of stentgrafts with high-volume of saline solution.

: Our aim was to determine the rate of ischemic stroke following thoracic endovascular aortic repair (TEVAR) after reducing gas volume released during stentgraft deployment by de-airing of thoracic stentgrafts with high-volume of 0.9% heparinized saline solution. : A single center retrospective analysis of all consecutive patients undergoing TEVAR from 2014 to 2019 was performed.

Type II endoleak and aortic aneurysm sac shrinkage after preemptive embolization of aneurysm sac side branches.

Objective: Type II endoleak (T2EL) is the most common endoleak after endovascular aneurysm repair (EVAR). Its optimal management has been controversially discussed. Thus, preliminary selective embolization of aneurysm sac side branches (ASSBs) has been adopted to prevent T2EL.

[Current concepts of perforated sigmoid diverticulitis].

Despite modern therapeutical options,perforated sigma diverticulitis still represents a life-threatening disease. In terms of diagnostic and therapeutic proceeding, the covered perforation has to be distinguished from free perforation.Primary therapeutic objective is the excision of the inflamed bowel segment to avoid abdominal sepsis.

A reliable tool to determine cell viability in complex 3-d culture: the acid phosphatase assay.

Cell-based assays are more complex than cell-free test systems but still reflect a highly artificial cellular environment. Incorporation of organotypic 3-dimensional (3-D) culture systems into mainstream drug development processes is increasingly discussed but severely limited by complex methodological requirements. The objective of this study was to explore a panel of standard assays to provide an easy-handling, standardized protocol for rapid routine analysis of cell survival in multicellular tumor spheroid-based antitumor drug testing.
