Current national and international guidelines recommend endovascular therapy of iliofemoral thromboses in young patients, as a treatment option to avoid the post-thrombotic syndrome. Possible techniques include endovascular local lysis therapy, as well as pharmacomechanical or purely mechanical procedures. Endovascular therapy of chronic obstruction of the inferior V. cava or pelvic veins is an effective therapy for patients suffering from post-thrombotic syndrome. If there is involvement of the V. femoralis communis, hybrid operations may be considered in which an AV fistula is formed or endophlebectomy is carried out...

BACKGROUND: Patients with iliofemoral deep venous thrombosis are at risk for development of post-thrombotic syndrome. Iliac vein stenting has been shown to significantly improve clinical outcomes in patients with venous outflow obstruction, although many studies include a heterogeneous population with several different venous pathologic processes. Our objective was to evaluate the results of iliocaval and infrainguinal venous intervention for venous outflow obstruction due to post-thrombotic chronic venous occlusive disease...

BACKGROUND: Selecting patients for iliofemoral vein stenting has traditionally relied on the identification and quantification of stenotic lesions with imaging such as multiplanar venography. Recently, intravascular ultrasound (IVUS) imaging has become more available. However, to date, the usefulness of these imaging modalities using the customary >50% treatment threshold for diameter (multiplanar venography) and area (IVUS) stenosis of iliofemoral veins has not been validated prospectively within the context of clinical improvement...

BACKGROUND: In patients with polycystic liver disease, development of cysts induces hepatic venous outflow obstruction (HVOO) and parenchymal modifications, challenging the paradigm of a normal non-cystic liver parenchyma. The aims were to reappraise the pathology of the non-cystic parenchyma, by focusing on HVOO lesions; and to investigate the association with outflow obstruction at imaging and perioperative course after liver resection. METHODS: This is a retrospective study conducted in one tertiary center between 1993 and 2014...

Budd‑Chiari syndrome (BCS) is an uncommon disease characterized by the occlusion or obstruction of hepatic venous outflow. The mechanism of BCS is still unclear and there are no accurate and effective diagnostic or therapeutic tools. In the present study, blood samples from BCS patients and healthy controls were used for RNA‑sequencing. The differentially expressed genes (DEGs) in BCS patients compared with healthy controls were identified. Gene Ontology (GO) enrichment analysis, Kyoto Encyclopedia of Genes and Genomes pathway analysis and Protein‑Protein Interaction (PPI) networks construction were performed for DEGs...

BACKGROUND: Venous outflow obstructions are rare anatomic findings that can present with symptoms of elevated intracranial pressure, including headache and vision loss, and can be mistaken for more common diagnoses, such as idiopathic intracranial hypertension (IIH) or cerebral venous sinus thrombosis (CVST). While venous outflow obstructions have been reported in rare bone dysplasias and congenital abnormalities, to date they have not been reported in renal osteodystrophy (ROD), a relatively common disorder seen in patients with chronic kidney disease...

Budd-Chiari syndrome (BCS) is a rare disease with an incidence of 0.1 to 10 per million inhabitants a year caused by impaired venous outflow from the liver mostly at the level of hepatic veins and inferior vena cava. Etiological factors include hypercoagulable conditions, myeloprolipherative diseases, anatomical variability of the inferior vena cava, and environmental conditions. Survival rates in treated patients range from 42 to 100% depending on the etiology and the presence of risk factors including parameters of Child-Pugh score, sodium and creatinine plasma levels, and the choice of treatment...

We present our experience for patients who have undergone an anatomic repair (AR) for congenitally corrected transposition of the great arteries (CCTGA) at the Children's Hospital of Wisconsin. A retrospective chart review of patients who underwent AR for CCTGA from 2001 to 2015 was performed. The cohort consisted of 15 patients (74% male). Median age of anatomic repair was 15 months (range 4.5-45.6 months). Four patients had a bidirectional Glenn (BDG) prior to AR. At the time of AR,-9 (60%) underwent Senning/Rastelli procedure, 4 (26...

BACKGROUND: The majority of iliac venous obstructions occur on the left side, and endovascular therapy has become the first line treatment for this condition. A left common iliac venous stent will protrude into the inferior vena cava (IVC) to some extent, thereby covering the contralateral common iliac vein (CIV) outflow. This may increase the risk of thrombosis of the contralateral iliac vein. The aim of this paper was to determine the rate of, and factors associated with, contralateral lower limb venous thrombosis after stenting, and to evaluate the results of salvage revascularisation...

BACKGROUND: Pseudotumor cerebri (PTC), also known as idiopathic intracranial hypertension (IIH), is a condition associated with increased intracranial pressure (ICP) in the absence of radiographic findings such as mass lesions or cerebral edema. CASE DESCRIPTION: We describe a case of progressive headache and visual disturbances attributed to PTC that resulted from subacute superior sagittal sinus (SSS) stenosis by a metastatic tumor. CONCLUSIONS: Venous outflow obstruction often presents with an acute symptomatology including infarcts, hemorrhages, and seizures, but only rarely does it cause the progressive development of raised ICP...

Living donor liver transplantation using the left liver graft with the middle hepatic vein (MHV) is a well-established procedure. Following such procedures, outflow obstruction occurs in remnant livers. However, the effects of the outflow-obstructed liver volume (LVOut-Ob ), with or without venous communication development, remain unclear. The aim of the study is to investigate effects of outflow-obstructed regions by focusing on short-term outcomes and remnant liver hypertrophy in left liver procurement donors...

Penile strangulation due to any solid encircling ornament or metal is rarely reported. Venous outflow obstruction due to any constricting item around the shaft leads to venous congestion, urinary obstruction, and rarely gangrene of the penile shaft skin. We report a case presenting with penile near-strangulation due to iron-lead metallic junction pipe which was cut using a heavy electric metal cutter.

PURPOSE OF REVIEW: This review describes the contributions of abnormal bone circulation to the pathophysiology of osteoarthritis. Combining dynamic imaging with MRI and PET with previous observations reveals that venous stasis and a venous outlet syndrome is most likely the key circulatory pathology associated with the initiation or progression of osteoarthritis. RECENT FINDINGS: MRI and PET have revealed that venous outflow obstruction results in physicochemical changes in subchondral bone to which osteoblasts are responsive...

REVIEW
Dominique-Charles Valla
BACKGROUND: Budd-Chiari syndrome (BCS) is a rare disease characterized by hepatic venous outflow tract obstruction (HVOTO). METHODS: Recent literature has been analyzed for this narrative review. RESULTS: Primary BCS/HVOTO is a result of thrombosis. The same patient often has multiple risk factors for venous thrombosis and most have at least one. Presentation and etiology may differ between Western and certain Eastern countries. Myeloproliferative neoplasms are present in 40% of patients and are usually associated with the V617F-JAK2 mutation in myeloid cells, in particular peripheral blood granulocytes...

BACKGROUND AND PURPOSE: Extracerebral venous congestion can precipitate intracranial hypertension due to obstruction of cerebral blood outflow. Conditions that increase right atrial pressure, such as hypervolemia, are thought to increase resistance to jugular venous outflow and contribute to cerebro-venous congestion. Cerebral pulsatility index (CPI) is considered a surrogate marker of distal cerebrovascular resistance and is elevated with intracranial hypertension. Thus, we sought to test the hypothesis that elevated right atrial pressure is associated with increased CPI compared to normal right atrial pressure...
