Diagnosis of Budd-Chiari syndrome.

Abdom Radiol (NY) 2018 Aug;43(8):1896-1907

Department of Radiology, Hôpital Beaujon, HUPNVS, 100, Bd du Général Leclerc, Clichy, France.

Budd-Chiari syndrome (BCS) is defined by clinical and laboratory signs associated with partial or complete impairment of hepatic venous drainage in the absence of right heart failure or constrictive pericarditis. Primary BCS is the most frequent type and is a complication of hypercoagulable states, in particular myeloproliferative neoplasms. Secondary BCS involves tumor invasion or extrinsic compression.

[Role of Intraoperative Indirect Channelography in Glaucoma Stent Implantation].

Klin Monbl Augenheilkd 2017 Nov 6;234(11):1378-1386. Epub 2017 Jul 6.

Augenklinik Berlin-Marzahn.

Several glaucoma stents are available to surgically reduce the intraocular pressure in primary open-angle glaucoma (POAG). In comparison to conjunctival opening procedures, the advantages of microinvasive glaucoma surgery (MIGS) are relatively atraumatic ab-interno procedures through a paracentesis, conjunctival sparing for later filtrating surgery, and possible combined cataract surgery. In this overview, the principle of intraoperative indirect channelography as a decision criterion for the individual selection of glaucoma stent implantation is presented. Read More

Evaluation of Venous Drainage Patterns for Skull Base Meningioma Surgery.

Neurol Med Chir (Tokyo) 2017 Oct 5;57(10):505-512. Epub 2017 Jun 5.

Department of Neurosurgery, School of Medicine, Fujita Health University.

The evaluation of venous drainage patterns prior to surgery for skull base meningioma is important owing to their deep location and the vulnerability of surrounding vascular structures. In recent years, the microsurgical skull base approach has matured as a surgical technique, making it an important option for reducing complications related to skull base meningioma surgery. In addition, knowledge of the venous anatomy can prevent venous drainage route disturbance and potentially life-threatening complications. Read More

An overview of the hemodynamic aspects of the blood flow in the venous outflow tract of the arteriovenous fistula.

J Vasc Access 2012 Jul-Sep;13(3):271-8

Department of Vascular Surgery, "Democritus" University of Thrace, University Hospital of Alexandroupolis, Alexandroupolis, Greece.

Upper limb vein aneurysms complicate all types of autogenous arteriovenous fistulae (AVF) and comprise false aneurysms secondary to venipuncture trauma as well as true aneurysms, characterized by dilatation of native veins. The dilatation of a normal vein and the development of a true aneurysm are strongly influenced by local hemodynamic factors affecting the flow in the drainage venous system and are also the target of operative interventions. This review article focuses on the description of these hemodynamic aspects which all physicians involved in the management of dialysis patients should be aware of. Read More

Overview of the CSF dual outflow system.

Authors:
Michael Pollay

Acta Neurochir Suppl 2012 ;113:47-50

University of Oklahoma College of Medicine, Sun City West, AZ, USA.

It was firmly established in the mid-twentieth century that the arachnoid villi represented an open pathway between the subarachnoid space and the dural venous sinuses. Intracellular and extracellular pathways within the villous structure provided the conduit for cerebrospinal fluid (CSF) and particulate matter. The importance of the lymphatic system was established by the demonstration of CSF tracers entering the nasal lymphatic system via the perineural subarachnoid space enveloping the olfactory nerve rootlets.

Venous drainage--gravity or assisted?

Authors:
F De Somer

Perfusion 2011 Sep;26 Suppl 1:15-9

Heart Centre, Gent, Belgium.

Since the early start of cardiopulmonary bypass, vascular access has been recognized as a main variable for obtaining optimal blood flow during cardiopulmonary bypass. In particular, venous drainage can limit the maximum flow as the wide, low-resistance, collapsible veins are connected with smaller stiff cannulas and tubing. Due to the introduction of long venous cannulas for minimally invasive cardiac surgery and the desire to limit hemodilution during cardiopulmonary bypass, more and more centers have started using assisted venous drainage techniques.

The surgical management of chronic subdural hematoma.

Neurosurg Rev 2012 Apr 10;35(2):155-69; discussion 169. Epub 2011 Sep 10.

Department of Neurological Surgery, Columbia University, College of Physicians & Surgeons, 710 West 168th Street, New York, NY 10032, USA.

Chronic subdural hematoma (cSDH) is an increasingly common neurological disease process. Despite the wide prevalence of cSDH, there remains a lack of consensus regarding numerous aspects of its clinical management. We provide an overview of the epidemiology and pathophysiology of cSDH and discuss several controversial management issues, including the timing of post-operative resumption of anticoagulant medications, the effectiveness of anti-epileptic prophylaxis, protocols for mobilization following evacuation of cSDH, as well as the comparative effectiveness of the various techniques of surgical evacuation.

The chronic cerebrospinal venous insufficiency syndrome.

Phlebology 2010 Dec;25(6):269-79

Vascular Disease Centre, Interventional Radiology Unit, University of Ferrara, 44100 Ferrara, Italy.

Chronic cerebrospinal venous insufficiency (CCSVI) is a syndrome characterized by stenosies of the internal jugular and/or azygous veins (IJVs-AZ) with opening of collaterals and insufficient drainage proved by reduced cerebral blood flow and increased mean transit time in cerebral MRI perfusional study. The present review is aimed to give a comprehensive overview of the actual status of the art of the diagnosis and treatment of this condition. As far as the origin of venous narrowing is concerned, phlebographic studies of the IJVs and AZ systems demonstrated that venous stenoses were likely to be truncular venous malformations; mostly, they are intraluminal defects such as malformed valve, septa webs.

The role of interventional radiology in the management of deep venous thrombosis: advanced therapy.

Cardiovasc Intervent Radiol 2011 Jun 7;34(3):445-61. Epub 2010 Oct 7.

Section of Interventional Radiology, Department of Radiology, University College Hospital Galway, Newcastle Road, Galway, Ireland.

Deep vein thrombosis (DVT) is often managed with a health care pathway that funnels patients to anticoagulation therapy alone. This "usual treatment" is designed to stop propagation and embolisation of venous thrombus but not remove it. Surgical thrombectomy was once the only option in severe cases in which limbs were threatened, but thrombus removal is no longer restricted to emergency cases. Read More

Normal and abnormal development of pulmonary veins: state of the art and correlation with clinical entities.

Int J Cardiol 2011 Feb 2;147(1):13-24. Epub 2010 Aug 2.

Department of Cardio-thoracic Surgery, University Medical Center Groningen, University of Groningen, The Netherlands.

Interest for the pulmonary veins has increased in the past decade after the potential arrhythmogenicity of the myocardial sleeve surrounding these structures has been recognized. Furthermore, there are several clinical entities, such as anomalous connection pattern and pulmonary vein stenosis, that are related to abnormal pulmonary vein development. In this review, we will describe current literature and aim to elucidate and reorganize current opinions on normal and abnormal pulmonary vein development in relation to clinical (management of) diseases.

Universitätsklinik für Hals-, Nasen- und Ohrenheilkunde und Poliklinik, Universitätsklinikum Freiburg, Freiburg.

Background: Because the tongue is an organ known for its excellent blood supply, ischaemic lingual necrosis is extremely rare within clinical everyday life. Acute lingual circulatory disturbances can result from impairment of venous drainage or more often from ischaemic arterial occlusion. Due to permanent function loss of the tongue, apparent lingual necrosis may lead to severe mutilation of the patient. Read More

The human pineal gland: relationships with surrounding structures and blood supply.

Neurol Res 2000 Dec;22(8):747-90

Laboratoire d'Anatomie, Faculté du Médecine et de Pharmacie, Place St. Jacques, 25000 Besancon, France.

After a short overview of the history of our knowledge of the pineal gland, its anatomy and its function, this work is primarily devoted to the relationships of the pineal gland to the nerve structures which delineate the pineal region. The complex surrounding blood vessels located in the quadrigeminal cistern are described with a special focus on the numerous venous trunks. Finally, the pineal blood supply is studied in three steps: (1) The arterial supply obtained through several groups of pineal arteries stemming mainly from the medial posterior choroidal arteries; (2) The venous drainage by the lateral pineal veins flowing, in most cases, into the cerebral vein of Galen; (3) The intrapineal vascular architecture with specific features concerning the central part of the gland highly vascularized by large sinusoid capillaries and its peripheral part poorly vascularized by small and fine blood vessels.

School of Biomedical Sciences, University of Nottingham Medical School, Queen's Medical Centre, UK.

The arterio-venous difference technique is now well established in the study of organ and tissue metabolism. This technique requires samples to be obtained of the arterial blood supplying and the venous drainage from a tissue, together with a measurement of the blood flow through the tissue. The technique is most appropriate when the arterial concentration and tissue metabolism of a substance are constant, and when the blood flow is stable. Read More

Perfusion Services, Cleveland Clinic Foundation, USA.

The introduction of minimally invasive approaches to cardiac surgery offered the opportunity to reduce patient's pain associated with median stemotomy as well as infection and postoperative bleeding. This technique required the use of one small venous cannula necessitating the implementation of kinetic assisted venous drainage (KAVD). However, KAVD proved costly due to the use of a centrifugal pump and could be de-primed if air was introduced into the venous line. Read More

Microvascular changes in venous disease: an update.

Angiology 1997 Jan;48(1):27-32

Department of Medicine, University Hospital, Zurich, Switzerland.

In an overview the microvascular involvement in chronic venous insufficiency (CVI) is described. Microangiopathy in the lower leg areas is characterized by the presence of typical enlarged and ramified blood capillaries, reduced capillary number, microvascular thrombosis and obliterations, and/or increased permeability of microlymphatics. Transcutaneous oxygen tension (tcPO2) is decreased and directly correlated to the number of perfused capillaries, whereas laser Doppler flux is enhanced. Read More
