Pradeep Sagar, R Rajesh, Mahesh Shanmugam, Vinaya Kumar Konana, Divyansh MishraIndian Journal of Ophthalmology 2018 66(6):872-876 The aim of this study is to compare the optical coherence tomography angiography (OCTA) and fundus fluorescein angiography (FFA) features of retinal capillary hemangioblastoma (RCH). This is an observational case series of three patients with von Hippel–Lindau (VHL) disease and one patient with juxtapapillary RCH. All patients underwent FFA with a mydriatic fundus camera and OCTA with swept-source angio OCT. The FFA and OCTA characteristics of tumors were compared. In our series, FFA coul...
Patient-based decision aids and other multimedia tools have been developed to help enrich the preoperative discussion between surgeon and patient. Use of these tools, however, can be time-consuming and logistically challenging. We investigated whether simply showing patients their images from preoperative computed tomography (CT) or angiography would improve patients' satisfaction with the preoperative discussion. We also examined whether this improved the patient's understanding and trust and whether it contributed to increased preoperative anxiety.
Cortical venous drainage (CVD) increases the probability of intracranial hemorrhage and mortality rate of dural arteriovenous fistulas (DAVF). Although digital subtraction angiography (DSA) is the most accurate method to determine CVD in DAVFs, this modality has limitations due to its invasive nature and radiation issues. The purpose of this study was to evaluate the diagnostic utility of arterial spin-labeling perfusion-weighted images (ASL-PWI) to identify CVD in patients with DAVF. The Institutional Review Board of our hospital approved this retrospective study. ASL-PWI features of 22 patients with DAVF were retrospect...
Conclusions: Significant anatomic variation exists between the right and the left cutaneous branches of deep circumflex femoral arteries. Hence, preoperative imaging by computed tomography angiography (CTA) aids in determination of the vascular anatomy of the descending branch of the lateral circumflex femoral artery and in selection of septocutaneous branches, thereby reducing operative time.

Conclusion The pilot study suggests that both decision aids are highly valued by patients with CAD. The booklet/DVD DA was associated with higher rates of complete review and improved knowledge about the management of stable coronary disease.
Conclusion The performance of intracranial vessel occlusion detection on CTA was improved with the availability of brain CT perfusion maps due to the improved detection of distal and posterior circulation vessel occlusions.
Conclusion: This proof-of-concept study employing a proteomic discovery platform offers insight into statin effects on novel immune pathways relevant to ASCVD progression in HIV. Novel biomarker discovery may enhance precision medicine strategies to estimate the efficacy of targeted therapies to reduce ASCVD progression and events in HIV.
