Outer retinal layer changes after dexamethasone implant for central retinal vein occlusion
Purpose: To analyze the outer retinal layer changes on spectral-domain optical coherence tomography after dexamethasone implant for the treatment of macular edema secondary to central retinal vein occlusions (CRVO). Methods: Thirty patients affected by macular edema related to CRVO (8 patients less than 50 years of age with nonischemic CRVO [50-niCRVO], and 10 patients with ischemic CRVO [iCRVO]) were included in a prospective study. After a comprehensive ophthalmologic examination, including best-corrected visual acuity, fluorescein angiography, and spectral-domain optical coherence tomography, each patient received a first implant. Further retreatments were performed on the basis of macular edema detection from the fourth month. Main outcome measure was the change in outer retinal layers at the 12-month examination. Results: The retinal layers of interest (external limiting membrane; ellipsoid zone; and retinal pigment epithelium) were classified as absent, disrupted, or present. The best baseline optical coherence tomography profile was found in
ConclusionsPreangiography levels of injury and repair biomarkers modestly predict the development of MAKE-D and can be used to improve the efficiency of future CA-AKI trials.

An 11-year-old boy with Klippel-Trenaunay syndrome with right lower extremity and pelvic venous ectasia underwent prophylactic embolization of persistent sciatic vein and markedly ectatic internal iliac vein using 24 coils (20 mm x 20 cm to 12 mm x 14 cm) (Nester; Cook Inc, Bloomington, Indiana) (Fig 1) to reduce risk of pulmonary embolism. He presented to the emergency department 3 days later with mild chest discomfort. Scout image from computed tomography (CT) pulmonary angiogram showed completely displaced coil nest in the chest (Fig 2).
Aortocaval fistula (ACF) is a rare but serious complication of ruptured abdominal aortic aneurysm (AAA). We discuss a 72-year-old man who presented with abdominal pain, acute renal failure, and bilateral leg phlegmasia. Computed tomography (CT) angiography confirmed an 8.5-cm AAA with ACF (Fig 1).
A 91-year-old man presented emergently with anterior neck pain, severe dysphagia, and neck expansion after a fall 1 day earlier. His oxygen saturation level was 88% on 4 L of oxygen. A triple-phase computed tomographic (CT) angiogram of the neck showed a massive prevertebral hematoma from a bleeding pseudoaneurysm (Fig 1). A right vertebral artery angiogram showed the prevertebral pseudoaneurysm to be supplied by a tiny muscular branch that was too small for selective transarterial catheterization (Fig 2).
ConclusionEVT of the true PcomA aneurysm is a safe and feasible procedure but may be associated with recurrence in midterm follow-up, requiring close surveillance and potential retreatment.
The term Ischemic cardiomyopathy(ICM) was originally coined by Dr. Burch from Tulane University, New Orleans, USA in 1970. For many decades there was skepticism regarding the existence of such entity. WHO classification over the years never included this term. ESC working group of 2008 (Elliott P, European Heart 29(2):270–276) decided not to include CAD as a cause for cardiomyopathy. Even the current MOGES system doesn’t invoke CAD as a cause for cardiomyopathy. But, I am sure, most of practicing cardiologists would agree, there is a need for such an entity. Why there is m...

AbstractPurposeTo assess and compare early changes in neuroinflammatory and vascular parameters in diabetic macular edema (DME) with subfoveal neuroretinal detachment (SND) after treatment with intravitreal dexamethasone (DEX-I) and ranibizumab (IVR).MethodsThirty-three eyes (33 patients) with treatment na ïve DME with SND were retrospectively evaluated at baseline and 2 months after DEX-I (15 eyes) and 1 month after 3 monthly IVR injections (18 eyes). Inclusion criteria were: complete eye examination, good quality OCT and OCT-A images. OCT parameters included: central macular thickness (CMT); numb er of hyp...
