Its collagen-dense architecture forms a resilient and adaptive continuum that varies in thickness, fiber orientation and anchoring patterns from the thigh to the foot. Recently, the use of high-resolution ultrasonography, supported by anatomical and histological evidence, revealed more intricate organization than traditionally illustrated. This is particularly true in the distal leg and ankle, where lattice-like fiber arrangements, retinacular thickenings and deep anchoring bands form a dynamically integrated support system. These features confirm the functional continuity of fascial layers throughout the limb and their relevance in maintaining tendon alignment-modulating load transfer and stabilizing the ankle/foot complex. This paper provides a concise and systematic guide to the sono-anatomy of lower-limb deep fasciae.

{"title":"Multiparametric Ultrasound in Budd-Chiari Syndrome: From Venous Outflow Obstruction to Microcirculatory Dysfunction.","authors":"Andrzej Fedak, Krystian Mirowski, Jan Jamroś, Agnieszka Czapska, Patrycja Mensah-Glanowska, Michal Kukla, Tadeusz Popiela","doi":"10.1002/jum.70495","DOIUrl":"https://doi.org/10.1002/jum.70495","url":null,"abstract":"&lt;p&gt;&lt;p&gt;Budd-Chiari syndrome (BCS) is a rare and potentially severe disorder of hepatic venous outflow with a heterogeneous anatomical and etiological spectrum. Obstruction may range from focal or segmental involvement of a single hepatic vein to multifocal hepatic venous disease with inferior vena cava (IVC) involvement. Although BCS is traditionally diagnosed by demonstrating macroscopic venous obstruction, its clinical severity also depends on the resulting changes in sinusoidal pressure, hepatic perfusion, collateral circulation, and the intrahepatic microcirculation. Paroxysmal nocturnal hemoglobinuria (PNH), although less common than myeloproliferative neoplasms as an underlying cause of BCS, represents a particularly severe prothrombotic model in which macrovascular thrombosis may coexist with systemic vascular and microcirculatory abnormalities. The purpose of the study is to provide a pathophysiology-oriented review of BCS, with emphasis on the relationship between hepatic venous outflow obstruction, altered hepatic hemodynamics, tissue perfusion, microcirculatory dysfunction, and the complementary role of conventional and advanced imaging techniques, using PNH as a model of severe thrombotic BCS. A narrative literature review was performed using PubMed/MEDLINE and related biomedical databases for publications from January 2000 to March 2026, supplemented by relevant earlier landmark studies. Literature addressing the etiology and pathophysiology of BCS, PNH-associated thrombosis, hepatic hemodynamics, conventional and advanced ultrasound techniques, computed tomography (CT), and magnetic resonance imaging (MRI) was reviewed. Particular attention was given to Doppler ultrasound, contrast-enhanced ultrasound (CEUS), parametric perfusion imaging, microvascular flow imaging, and elastography. BCS results from a broad spectrum of primary and secondary causes, including myeloproliferative neoplasms, PNH, inherited and acquired thrombophilia, malignancy, trauma, and iatrogenic conditions. The anatomical extent and duration of venous obstruction determine the degree of sinusoidal hypertension, hepatic congestion, redistribution of portal and arterial flow, and development of intrahepatic collateral pathways. Conventional Doppler ultrasound remains the foundation of diagnosis and provides assessment of venous patency, the extent of obstruction, waveform abnormalities, portal and arterial hemodynamics, and collateral circulation. CEUS and parametric perfusion imaging provide complementary information regarding regional and temporal hepatic perfusion, while microvascular flow imaging may demonstrate slow residual flow and small collateral pathways not readily visualized with conventional Doppler. Elastography provides additional information regarding congestion-related tissue stiffness and chronic remodeling. CT and MRI remain essential for comprehensive anatomical characterization, identification of secondary causes, assessment of parenchymal compl","PeriodicalId":17563,"journal":{"name":"Journal of Ultrasound in Medicine","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present the ultrasound characteristics of this entity and emphasize the value of high-resolution dermatologic ultrasound both as a diagnostic tool and for detailed lesion assessment in SNC. A retrospective, descriptive cross-sectional study was performed in patients with a clinical diagnosis of nevus comedonicus. Clinical and sonographic information was collected. All participants underwent ultrasound evaluation of the affected area, the contralateral region, and additional anatomical sites commonly involved in HS. Examinations were carried out using color Doppler ultrasound with high-frequency probes (18 and 24 MHz) and an ultra-high-frequency 71 MHz transducer. Severity was staged ultrasonographically in all patients using the mSOS-HS classification. Six patients met the inclusion criteria. In every case, ultrasound demonstrated features analogous to those typically observed in HS within the examined zones. However, in contrast to HS, clinical SNC lesions consistently followed a linear or segmental pattern and were exclusively unilateral. Ultrasonographic findings included follicular dilatations, pseudocysts, tunnels, dermal and subcutaneous inflammatory collections, and reduced dermal echogenicity accompanied by signs of local inflammation (hypervascularity). Overall, the ultrasound characteristics of SNC mirror a localized, segmental form of HS occurring in non-typical HS locations, strongly supporting a potential etiological link between the 2 disorders.
