This condition is typically idiopathic and can be associated with various infections or malignancies. Recently, FBA has been linked to COVID-19 in some reports. This report describes a rare association between COVID-19 and FBA and presents characteristic findings from multimodal imaging. We describe the case of a 30-year-old man, otherwise healthy, who experienced acute vision loss in his left eye 1 week after testing positive for COVID-19. His initial visual acuity was 20/20 in the right eye and counting fingers at 2 feet in the left eye. A fundus examination disclosed extensive vascular sheathing affecting the arteries and veins, accompanied by widespread intraretinal, preretinal, and subretinal hemorrhages indicative of FBA. Fundus fluorescein angiography revealed notably delayed filling in both arterial and venous systems. Optical coherence tomography of the left eye displayed inner retinal layer hyperreflectivity, suggesting ischemia coupled with substantial subretinal fluid. The systemic evaluation of the patient was unremarkable. The treatment included systemic corticosteroids, azathioprine, intravitreal bevacizumab, and panretinal photocoagulation. After 6 months of treatment, the left eye examination showed resolution of vascular sheathing, retinal hemorrhages, and subretinal fluid, although the final visual acuity in the left eye remained unchanged.

However, limiting instrument inventory and simplifying surgical procedures are also desirable to reduce costs. In a multicenter study, we assessed the feasibility of robotic lobectomy with a single type of robotic stapler [SureForm45 Curved-Tip (SF45C); Intuitive Surgical Inc.] inserted through one 12-mm port placed at the anterior tip of the lower intercostal space. We also investigated the potential cost savings of using an additional 60-mm stapler for interlobar division. A total of 135 lobectomy cases were enrolled. In all cases, all stapling procedures were completed using the SF45C inserted from the designated 12-mm port. We found that it was potentially less expensive to use the SureForm60 stapler if more than six SF45C reloads were needed for interlobar division. However, in our series, only 1 case (0.7%) met this requirement. The use of a single type of stapler from one 12-mm port in a robotic lobectomy is technically feasible.

This study aimed to investigate the efficacy of intravenous injection of RACs in reducing stroke volume and increasing anti-inflammatory and angiogenic factors in mice with focal cerebral ischemia. Mice with occluded MCAs received intravenous injections of phosphate-buffered saline (PBS) (control), low-dose RACs, or high-dose RACs. The proximal part of the left MCA was occluded to induce permanent focal ischemia. After 3 days, we administered PBS or low-dose (1 × 10<sup>4 </sup>/50 µL) or high-dose RACs (1 × 10<sup>5 </sup>/50 µL) through the tail vein and assessed the infarct volume on day 7. High-dose RACs significantly decreased infarct volume compared to PBS, whereas low-dose RACs showed no effect. The number of interleukin-10 (IL-10)-positive and vascular endothelial growth factor (VEGF)-positive cells in the peri-infarct area on day 7 was significantly higher in mice treated with low-dose and high-dose RACs than in the PBS control group. Intravenous injection of RACs can reduce ischemic stroke volume; however, a higher dose of RACs is required than the dose used in intraarterial transplantation.
