Developmental venous anomalies (DVAs) are usually asymptomatic. We report a case of DVA thrombosis with recurrent tiny frontal hematoma in a 24-year-old man. The contribution of T2-GRE and SWAN sequences are discussed. Follow-up attested complete recanalization after anticoagulation.

Pulmonary venous developmental anomalies have historically been evaluated using echocardiography and catheter-based angiography. In recent years, however, multidetector CT angiography (MDCTA) and MR angiography have become increasingly important tools for detailed characterization of these anomalies. This case report provides an in-depth review of the radiologic findings in a 15-year-old patient diagnosed with the supracardiac type of Total Anomalous Pulmonary Venous Connection (TAPVC).

Objective: Short stature, central hypothyroidism and infertility are common in those with a Fontan circulation. Given that the Fontan circulation often results in hepatic portal venous congestion, we hypothesize that the hypothalamic-pituitary portal circulation is also affected, contributing to subsequent hypothalamic-pituitary axis dysfunction.
Methods: MRI data from the Australian and New Zealand Fontan Registry (86 cases) was compared to 86 age- and sex-matched normal published controls.

We sought to characterize cellular composition across the cardiovascular system of the healthy Wistar rat, an important model in preclinical cardiovascular research. We performed single-nucleus RNA sequencing (snRNA-seq) in 78 samples in 10 distinct regions, including the four chambers of the heart, ventricular septum, sinoatrial node, atrioventricular node, aorta, pulmonary artery, and pulmonary veins, which produced 505,835 nuclei. We identified 26 distinct cell types and additional subtypes, with different cellular composition across cardiac regions and tissue-specific transcription for each cell type.

Background: The ability to generate endogenous Cre recombinase drivers using CRISPR-Cas9 knock-in technology allows lineage tracing, cell type specific gene studies, and validation of inferred developmental trajectories from phenotypic and gene expression analyses. This report describes endogenous zebrafish Cre and CreERT2 drivers generated with GeneWeld CRISPR-Cas9 precision targeted integration.
Results: and knock-ins crossed with ubiquitous -based Switch reporters led to broad labeling in expected mesodermal and neural crest-derived lineages in cardiac, pectoral fins, pharyngeal arch, liver, intestine, and mesothelial tissues, as well as enteric neurons.

Background: The lower limb venous system, a subject of extensive study due to its high clinical significance on deep vein thrombosis, presents a rare, intriguing, symmetrical variant in this dissection report.
Case Report: We present the uncommon and clinically meaningful bilateral persistent sciatic vein (PSV) variant. The developmental variant was symmetrically detected during a dissection of an 81-year-old female donated cadaver.
