Purpose: To report the use of a balloon catheter to facilitate percutaneous ultrasound-guided thrombin injection of a subclavian artery pseudoaneurysm.
Case Report: A 36-year-old man presented with hoarseness after the insertion of a right temporary internal jugular line. Arteriography showed a short neck right subclavian artery pseudoaneurysm. A 6 mm × 40 mm balloon catheter was positioned across the neck of the pseudoaneurysm to permit percutaneous ultrasound-guided thrombin injection. Immediate post-treatment angiogram demonstrated no filling of the pseudoaneurysm. Seven-month clinical and imaging follow-up confirmed resolution of the pseudoaneurysm and hoarseness.
Conclusions: This clinical vignette highlights the potential of balloon catheter-assisted percutaneous ultrasound-guided thrombin injection as an alternative to open or endovascular repair of pseudoaneurysms of the subclavian arteries.

Subclavian artery pseudoaneurysm (SAP) is a rare but lethal diagnosis, and an important condition that should be detected and managed imperatively. SAP has been seldom described in the literature, explaining the lack of concrete management guidelines. Herein we present a case study of a 63-year-old man with SAP post a transcatheter aortic valve implantation (TAVI) done 8 days prior to current presentation.

Purpose: This study explores the potential interaction of brolucizumab with platelets and its effects on platelet activation and reactivity, crucial in retinal vasculitis and retinal vascular occlusion. Safety concerns remain of interest, although brolucizumab showed superior retinal efficacy and reduced injection frequency compared to other licensed anti-VEGF agents.
Methods: Resting and activated platelets of healthy volunteers were pretreated with brolucizumab at the following concentrations 0.

Objective: To investigate the safety and effectiveness of balloon occlusion and intra-sac thrombin injection in the endovascular repair of ruptured abdominal aortic aneurysm.
Methods: From October 2019 to October 2022, the clinical data of 16 patients with rAAA treated with balloon occlusion technique and intra-sac thrombin injection combined with EVAR were retrospectively analyzed, including 13 males and 3 females, aged 42-85 years, with a median age of 70.5 years.

Pseudoaneurysms develop as a result of disruption of the arterial wall due to trauma or iatrogenic reasons such as catheterization, and it is important due to the high risk of bleeding and rupture. Until recently, the main treatment of pseudoaneurysms was surgical repair. However, in recent years, minimally invasive methods such as ultrasound-guided compression and percutaneous thrombin injection have been used more frequently.

Article Synopsis
- - The study focuses on in situ injectable hydrogels, which are important for applications in regenerative medicine and drug delivery, but face challenges in controlling gelation speed for easier injection.
- - Researchers investigated a system using bispecific aptamers that can inhibit thrombin (an enzyme involved in clotting) to slow down the formation of fibrin hydrogels.
- - The study found that when these aptamers interacted with complementary sequences, they could reverse the inhibition, speeding up the hydrogel formation process, demonstrating a new dynamic control for enzyme-mediated hydrogel development.
