Purpose: To report a case of central retinal vein occlusion in a young patient after the use of amyl nitrate "poppers."
Methods: Description of the patient's clinical history, ophthalmic examination, retinal imaging, and treatment.
Results: A 38-year-old man presented with a central retinal vein occlusion in his right eye after inhaling amyl nitrite "poppers." There appeared to be a definitive temporal association between poppers use and both the onset of the vein occlusion and the patient's visual scotomata, which recurred immediately after drug use multiple times. Optical coherence tomography displayed cystic macular edema, which was treated with intravitreal bevacizumab. The patient's hypercoagulable laboratory workup was negative.
Conclusion: This is the first report of a central retinal vein occlusion associated with poppers inhalation. A high index of suspicion for poppers use should be maintained in young patients who present with retinal vein occlusion, particularly in homosexual patients with a normal laboratory workup that fails to reveal a hypercoagulable etiology.

May-Thurner syndrome is an anatomical anomaly characterized by venous compression of the iliac vein by the arterial system. It is more common in women. It may be asymptomatic or lead to symptoms related to hypertension/venous occlusion, namely, edema of the lower limb.

Although typically associated with haematopoietic stem cell transplantation, VOD/SOS may also occur following intensive multimodal chemotherapy regimens. In children, symptoms of VOD/SOS are refractory thrombocytopaenia, weight gain, hepatomegaly, ascites and fluid retention, hyperbilirubinaemia and sometimes right upper quadrant pain.

Background: The aim of the study was to explore a feasible method for alleviating limb ischemia-reperfusion injury (LI/RI) through the use of a high-concentration citrate solution (HC-A solution) for limb perfusion (LP).
Methods: Eighteen pigs were divided into three groups: the Sham group, LI/RI group, and HCA group. The Sham group underwent exposure of the iliac artery and vein.

Pulmonary hypertensive changes are commonly seen by the surgical pathologist, but the majority represents secondary changes due to some process extrinsic to the lung. Some primary, or idiopathic, vascular diseases result in unique pathologic changes including the plexiform lesion and venous hypertensive changes. Thromboembolic disease also shows unique pathologic features.

Retinal vein occlusion (RVO) has become the second most common retinal vascular disease after diabetic retinopathy. Existing therapeutic approaches, including intravitreal injection of antivascular endothelial growth factors (anti-VEGFs) and/or glucocorticoids and laser therapy, primarily address secondary macular edema and neovascularisation. However, these strategies do not address the underlying cause of the disease and may have harmful side effects.
