In 20 patients the fibrinolytic capacity was assessed by the venous occlusion test and by stimulation with DDAVP injection (0.4 microgram/kg). Irrespective of the test used, all cases were classified into the same group of responsiveness (responder, low responder, non-responder) with the exception of one patient. DDAVP injection caused subjective discomfort only in some cases, while the venous occlusion test was invariably accompanied by pain.

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.

Branch retinal vein occlusion (BRVO) is a common retinal vascular condition and a significant contributor to vision loss worldwide, particularly in middle-aged and elderly populations. This review synthesizes current knowledge on the epidemiology, pathogenesis, and clinical features of BRVO, alongside recent advancements in diagnostic and therapeutic strategies. BRVO is approximately four times more prevalent than central retinal vein occlusion (CRVO) and often leads to significant vision impairment.

Retinal vein occlusion (RVO) is the leading cause of vision loss due to an obstruction in the retinal venous system. While RVO is often linked to thrombotic tendencies and coagulation abnormalities, the exact role of coagulation traits in its development is not fully understood. This study aims to investigate the potential causal relationship between coagulation traits and the risk of RVO by analyzing publicly available genome-wide association study (GWAS) summary statistics.

Objective: In this study, we aimed to retrospectively review patients with post-thrombotic syndrome (PTS) and investigate its long-term outcomes, and a novel classification were presented across multiple institutions.
Methods: We retrospectively evaluated patients with PTS who underwent endovascular therapy at two institutions between January 2018 and September 2023. Baseline patient demographics, lesion characteristics, and in-hospital and follow-up outcomes were collected and analyzed retrospectively.
Shunt Dependency Syndrome Combined with Sinus Stenosis after Cyst-peritoneal Shunting of Arachnoid Cyst: A 20-year Rare Complication.

Department of Neurology, The Second Affiliated Hospital of Xi'an Jiaotong University, Xi'an, China.
Shunt dependence syndrome is a serious long-term complication characterized by symptoms and signs of increased intracranial pressure with normal-sized lateral ventricles after several years of arachnoid cyst-peritoneal shunting. It is easy to misdiagnose and overlook when combined with sinus stenosis, thus delaying treatment. Here, we present a 35-year-old man with an unexplained headache and binocular horizontal diplopia with high intracranial pressure.
