A Review of Antithrombotic Treatment in Critical Limb Ischemia After Endovascular Intervention

Cardiology and Therapy, 2019
Endovascular intervention is often used to treat critical limb ischemia (CLI). Post-intervention treatment with antiplatelet and/or anticoagulant therapy has reduced morbidity and mortality due to cardiovascular complications.

A Novel Sample-efficient Deep Reinforcement Learning with Episodic Policy Transfer for PID-Based Control in Cardiac Catheterization Robots [PDF]

arXiv, 2021
Robotic catheterization is typically used for percutaneous coronary intervention procedures nowadays and it involves steering flexible endovascular tools to open up occlusion in the coronaries. In this study, a sample-efficient deep reinforcement learning with episodic policy transfer is, for the first time, used for motion control during robotic ...

ANGIOPLASTY AND STENTING OF BASILAR ARTERY WITH SHORT-TERM RESULTS

ARYA Atherosclerosis, 2010
Symptomatic basilar artery stenosis has a poor prognosis. Surgical bypasses are technically demanding and of no proven benefit. A new generation of intravascular stents that are flexible enough to navigate the tortuosities of the vertebral artery may ...

Systematic review of endovascular intervention and surgery for common femoral artery atherosclerotic disease

British Journal of Surgery, 2018
Endovascular intervention has emerged as a potential alternative to open surgery in treating common femoral artery (CFA) atherosclerotic disease. The aim of this systematic review was to assess the safety and efficacy of both techniques.

Endovascular image‐guided interventions (EIGIs) [PDF]

Medical Physics, 2007
Minimally invasive interventions are rapidly replacing invasive surgical procedures for the most prevalent human disease conditions. X‐ray image‐guided interventions carried out using the insertion and navigation of catheters through the vasculature are increasing in number and sophistication. In this article, we offer our vision for the future of this

Uterine artery embolisation for uterine myoma — a case series

Лечащий Врач
Background. To date, there is quite a lot of international experience with uterine artery embolisation. This method is an alternative to classical myomectomy and differs from it by less invasiveness and surgical trauma, and faster rehabilitation ...

Endovascular therapy for ischemic stroke with perfusion-imaging selection.

New England Journal of Medicine, 2015
BACKGROUND Trials of endovascular therapy for ischemic stroke have produced variable results. We conducted this study to test whether more advanced imaging selection, recently developed devices, and earlier intervention improve outcomes.

Autonomous navigation of catheters and guidewires in mechanical thrombectomy using inverse reinforcement learning [PDF]

Int J CARS (2024)
Purpose: Autonomous navigation of catheters and guidewires can enhance endovascular surgery safety and efficacy, reducing procedure times and operator radiation exposure. Integrating tele-operated robotics could widen access to time-sensitive emergency procedures like mechanical thrombectomy (MT).

Randomized assessment of rapid endovascular treatment of ischemic stroke.

New England Journal of Medicine, 2015
BACKGROUND Among patients with a proximal vessel occlusion in the anterior circulation, 60 to 80% of patients die within 90 days after stroke onset or do not regain functional independence despite alteplase treatment.

Combination antifungal therapy for treatment of Candida parapsilosis prosthetic valve endocarditis and utility of T2Candida Panel®: A case series

IDCases, 2019
Although Candida species are common pathogens for nosocomial infections, Candida endocarditis is still considered a rare entity. Here, we report two cases of Candida parapsilosis endovascular infections in patients with prosthetic valves, both of which ...
