Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Rare case of inflammatory abdominal aortic aneurysm with an aortocaval fistula

Radiology Case Reports
Inflammatory abdominal aortic aneurysms (IAAA) are a distinct subcategory of abdominal aortic aneurysms that make up roughly 5%-10% of all abdominal aortic aneurysm (AAA) cases.

Abdominal aortic aneurysm in women [PDF]

Journal of Vascular Surgery, 2001
The purpose of this study was to compare abdominal aortic aneurysm (AAA) associations in men and women.Veterans aged 50 to 79 years without a previous history of AAA underwent ultrasound screening for AAA after completing a questionnaire on demographic information and potential risk factors.A total of 122,272 men and 3450 women were successfully ...

Increased Disarray of Extracellular Matrix Collagen‐I Fiber Network and Compromised Biomechanics in Aortae From Marfan‐Syndrome Mice Assessed Through Combined Opto‐Biomechatronics

Advanced Science, EarlyView.
Combined structure‐function assessment in aortic rings from Marfan mice using MechaMorph Opto‐Biomechatronics technology relates increased elasticity (stiffness) and dynamic viscosity and less ordered extracellular matrix 3D‐structure (collagen) as potential causes for impaired Windkessel function and compromised haemodynamics in Marfan's syndrome ...

Placement of an aortomonoiliac stent graft without femorofemoral revascularization in endovascular aneurysm repair: a case report [PDF]

, 2011
Introduction: Endovascular aortic repair, if technically feasible, is the treatment of choice for patients with a contained ruptured aortic aneurysm who are unfit for open surgery. Case presentation: We report the case of an 80-year-old Caucasian man who

ROS‐Responsive Nanoparticle Delivery of Dexmedetomidine Protects the Gut Vascular Barrier After Intestinal Ischemia/Reperfusion via the HDAC‐H3K27ac‐TCF4 Axis

Advanced Science, EarlyView.
A low dose of dexmedetomidine, delivered by ROS‐responsive nanoparticles, preferentially accumulates in the ischemic intestine and restores gut vascular barrier integrity after ischemia/reperfusion injury. This nanoparticle‐based strategy prevents bacterial translocation and liver damage without cardiorespiratory side effects, working through HDAC ...

Long Noncoding RNAs in Aortic Dissection: Mechanistic Roles and Therapeutic Potential

AGING MEDICINE, EarlyView.
Aortic dissection (AD) involves vascular inflammation, VSMC dysfunction, and ECM degradation. LncRNAs regulate AD progression via ceRNA networks, with great potential as diagnostic biomarkers and therapeutic targets, while further clinical validation is needed.

Radical Resection of the Third Portion of the Duodenum for Secondary Aortoduodenal Fistula

Annals of Gastroenterological Surgery, EarlyView.
Secondary aortoduodenal fistula most commonly involves the third portion of the duodenum and requires definitive management of both vascular and gastrointestinal components. We demonstrate a step‐by‐step technique for radical duodenal resection and reconstruction performed in structured collaboration with cardiovascular surgeons.

Prevalence of abdominal aortic aneurysms: a screening program in São Paulo, Brazil

São Paulo Medical Journal
CONTEXT: Abdominal aortic aneurysm is an asymptomatic but potentially fatal condition. Elective surgery can prevent death from rupture, and is indicated for aneurysms larger than 45 mm. Because aneurysms tend to grow with time, detection of small ones (>

Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation

Advanced Intelligent Systems, EarlyView.
This work introduces a novel bioelectric navigation system eliminates the need for harmful fluoroscopy during endovascular surgeries. A bespoke 16‐electrode catheter is fabricated using rapid thermal drawing and laser micro‐machining. Paired with a real‐time tracking algorithm fusing vascular geometry detection and distance estimation, this technology ...
