For over 20 years, interventional methods have improved the outcomes of patients with cardiovascular disease or stroke. However, these procedures require an intricate combination of visual and tactile feedback and extensive training periods. An essential part of this training relates to catheter or guidewire manipulation. In this paper, we propose a composite model to realistically simulate a c...

Background: Tiny false intracranial rupture aneurysms are particularly rare. It is challenged both to neurosurgery and endovascular treatment. Methods: We present here five rare cases of perforator tiny aneurysms that were diagnosed based on DSA. These patients were found due to SAH, and they decided to treat these aneurysms with endovascular therapy. After numerous attempts, the coiling microc...

Ultrasound (USG) guidance has long been used for guiding central venous catheterization. USG provides direct visualization of needle puncture through the skin into the vein. Most of the time USG guidance is just limited to puncturing of the vein and seeing guidewire entering the vein while malpositioning of catheter occurs after that which is seen later on while checking chest radiograph. Repos...

Various endoscopic techniques have been developed to overcome the difficulties in biliary or pancreatic access during endoscopic retrograde cholangiopancreatography, according to the preference of the endoscopist or the aim of the procedures. In terms of endoscopic methods, guidewire-assisted cannulation is a commonly used and well-known initial cannulation technique, or an alternative in cases...

Entrapment and fracture of carotid angioplasty and stenting hardware is a rare complication of percutaneous stenting procedures. We describe a case of a retained distal filter embolic protection device and guidewire in a 57-year-old male in Beijing, China. After unsuccessful attempts at removal via interventional methods, a second stent was deployed to secure the original hardware in situ, and ...

We report the successful conversion of percutaneous cholecystostomy (PC) to endoscopic transpapillary gallbladder stenting (ETGS) with insertion of an antegrade guidewire into the duodenum. An 84-year-old man presented with severe acute cholecystitis and septic shock. He had significant comorbidities, and emergent PC was successfully performed. Subsequent ETGS was attempted but unsuccessful owi...

At present, most vascular intervention surgical robots (VISRs) cannot achieve effective force feedback and lack regulation of the clamping guidewire. In this paper, a VISR based on is proposed. It master–slave system consisting master manipulator that flexible enough slave wire feeder can deliver Accurate established to ensure safety operation, guidewire be regulated in real time. Based dynamic...
