reflux in the internal jugular and vertebral veins, reflux in the deep cerebral veins, high-resolution B-mode ultrasound evidence of stenosis of the internal jugular vein, absence of flow in the internal jugular or vertebral veins on Doppler ultrasound, and; reverted postural control of the main cerebral venous outflow pathways.
The first description of thrombosis of the cerebral veins and sinuses is attributed to the French physician Ribes, who in 1825 observed thrombosis of the sagittal sinus and cerebral veins in a man who had had seizures and delirium. [29] Until the second half of the 20th century it remained a diagnosis generally made after death. [30]
Venography (also called phlebography or ascending phlebography) is a procedure in which an X-ray of the veins, a venogram, is taken after a special dye is injected into the bone marrow or veins. The dye has to be injected constantly via a catheter, making it an invasive procedure.
The veins puncture the relevant dural sinus, piercing the arachnoid and dura mater as bridging veins that drain their contents into the sinus. [5] The deep venous system. The deep venous system is primarily composed of traditional veins inside the deep structures of the brain, which join behind the midbrain to form the great cerebral vein (vein ...

AP chest x-rays are harder to read than PA x-rays and are therefore generally reserved for situations where it is difficult for the patient to get an ordinary chest x-ray, such as when the patient is bedridden. In this situation, mobile X-ray equipment is used to obtain a lying down chest x-ray (known as a "supine film").
Deep cerebral vein thrombosis is a rare [7] condition characterized by the presence of a blood clot in the deep cerebral veins and can appear in the septal veins. [8] This condition is commonly comorbid with other thrombi in the cerebral veins.
3D model of cerebral veins. In human anatomy, the cerebral veins are blood vessels in the cerebral circulation which drain blood from the cerebrum of the human brain. They are divisible into external (superficial cerebral veins) and internal (internal cerebral veins) groups according to the outer or inner parts of the hemispheres they drain into.
