Cerebral Vessels: An Overview of Anatomy, Physiology, and Role in the Drainage of Fluids and Solutes.

Front Neurol 2020 13;11:611485. Epub 2021 Jan 13.

Faculty of Medicine, University of Southampton, Southampton, United Kingdom.

The cerebral vasculature is made up of highly specialized structures that assure constant brain perfusion necessary to meet the very high demand for oxygen and glucose by neurons and glial cells. A dense, redundant network of arteries is spread over the entire pial surface from which penetrating arteries dive into the cortex to reach the neurovascular units. Besides providing blood to the brain parenchyma, cerebral arteries are key in the drainage of interstitial fluid (ISF) and solutes such as amyloid-beta. Read More

Determining Optimal Routes to Surgery for Borderline Resectable Venous Pancreatic Cancer-Where Is the Least Harm and Most Benefit?

Front Oncol 2019 17;9:1060. Epub 2019 Oct 17.

Department of HPB Surgery and Liver Transplant, University Hospitals of Birmingham NHS Foundation Trust, Birmingham, United Kingdom.

Surgery among patients with borderline resectable pancreatic cancer (BRPC) and venous disease has emerged as a viable strategy to achieve curative treatment. By definition, these patients are at increased risk of a positive resection margin, however, controversy exists with regards to necessity of radical surgery and optimum pathways with no consensus on definitive treatment. A surgery first approach is possible though outcomes vary but patients can have an efficient pathway to surgery, particularly if biliary drainage is avoided which limits overall complications.

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

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 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
