Robotic surgical systems are becoming increasingly popular for the treatment of cardiovascular diseases. However, most of them have been designed without considering techniques and skills of natural surgical manipulations, which are key factors to clinical success of percutaneous coronary intervention. This paper proposes an HMM-based framework to recognize six typical endovascular manipulations for surgical skill analysis. A simulative surgical platform is built for endovascular manipulations assessed by five subjects (1 expert and 4 novices). The performances of the proposed framework are evaluated by three experimental schemes with the optimal model parameters. The results show that endovascular manipulations are recognized with high accuracy and reliable performance. Furthermore, the acceptable results can also be applied to the design of next generation vascular interventional robots.

Coronary vasospasm involves constriction of the coronary arteries and has been described after manipulation of the coronary arteries (ie, after stenting or bypass grafting). This report details the case of a 57-year-old man who presented with an endoleak after thoracic endovascular aortic repair. He underwent a frozen elephant trunk procedure and postoperatively had diffuse coronary vasospasm, demonstrated on pre- and post-vasospasm cardiac catheterization.

Objective: A Leonis Mova (LM; SB Kawasumi, Kanagawa, Japan), one of the steerable microcatheters, has a remote-controlled flexible catheter tip manipulated with a dial in the hand grip, which enables operators to overcome complicated branching in endovascular surgeries. We report a case of a pituitary tumor in which the LM worked effectively as a distal access catheter (DAC) in tumor embolization.
Case Presentation: A female patient in her 70s complained of bitemporal hemianopsia, and an MRI revealed a pituitary tumor that appeared hypervascular.

Background: The use of endovascular procedures is becoming increasingly popular across multiple clinical domains. These procedures are generally performed under image guidance using an interventional c-arm x-ray system. Radiation exposure to both patients and interventional staff due to use of fluoroscopy is a health and occupational concern, but modifications to the interventional workflow to address radiation may come at the cost of procedure time or quality.

Bacterial contamination of angiographic materials and fluids has been shown to occur during human angiographic procedures. Angiographic examinations and experiments must be performed under sterile conditions to avoid complications due to contamination and possible subsequent infections. However, data regarding the frequency and the clinical consequences are limited.
