The Carboclip is a no-needle vascular access device made of an inverted Titanium body. The horizontal bar of 6 mm inner diameter is connected with artery and vein via a vascular graft. The vertical body houses an elastic plug in which is inserted a double canula diving in the blood stream for extracorporeal blood circulation (EBC). The body is wrapped by a flange made of microporous biocarbon in which the subcutaneous fibroblast will growth, forming an antimicrobial barrier and fixing the port to the skin. We report our experience on 30 devices implanted in 30 sheep with 26 extracorporeal circulation simulating hemodialysis. The results demonstrate good tightness of the plug as well at rest as during EBC procedure, sufficient blood flow rate of about 400 ml/min, and benefits of the microporous carbon flange.

Objective: To evaluate the safety and efficacy of the area reduction post-closure technique for bedside weaning of veno-arterial extracorporeal membrane oxygenation (V-A ECMO).
Methods: A retrospective study was conducted from December 2022 to November 2023, analyzing data from patients who underwent V-A ECMO weaning at our center. The area reduction post-closure technique, utilizing two ProGlide devices (Abbott Vascular, Santa Clara, CA), was adopted as a standard practice.

A 53-year-old woman undergoing combination therapy with epidermal growth factor receptor (EGFR) and vascular endothelial growth factor receptor (VEGFR) inhibitors for advanced lung cancer with brain metastases developed pustules and punctate purpura on both lower extremities. Histopathological examination revealed neutrophilic infiltration around the hair follicles and erythrocyte extravasation in the perivascular regions near the hair roots, leading to a diagnosis of purpuric papulopustular eruptions. The rash improved with oral doxycycline (100 mg/day) and topical corticosteroids.
