Superior sagittal sinus thrombophlebitis

Introduction to superior sagittal sinus thrombophlebitis Upper sagittal sinus thrombophlebitis refers to acute frontal sinusitis, and the forehead infection and other trauma causes the bacteria to flow into the superior sagittal sinus through the frontal plate vein or the anterior sacral sinus, causing thrombosis of the superior sagittal sinus. Phlebitis. Pathological changes vary depending on the etiology and route of infection. Patients caused by frontal sinus sinus inflammation and frontal bone osteomyelitis, due to blood flow, can enter the sagittal sinus with bacteria or bacteria thrombus with blood, vasculitis, endothelial detachment . basic knowledge The proportion of illness: 0.002% Susceptible people: no special people Mode of infection: non-infectious Complications: osteomyelitis, subarachnoid abscess, epidural abscess, edema, brain abscess

Cause of superior sagittal sinus thrombophlebitis

Acute frontal sinusitis, acute frontal osteomyelitis, subarachnoid abscess or frontal infective trauma, bacteria flow into the superior sagittal sinus through the frontal plate vein or anterior sacral vein, which can cause thrombosis of the sinus Sexual phlebitis, an epidural abscess can also cause this disease.

Pathological changes vary depending on the etiology and route of infection. Patients caused by frontal sinus sinus inflammation and frontal bone osteomyelitis, due to blood flow, can enter the sagittal sinus with bacteria or bacteria thrombus with blood, vasculitis, endothelial detachment The thrombus is formed due to slow blood flow. The right otogenic sigmoid sinus thrombus can reversal blood flow to the superior sagittal sinus, but it occurs slowly. The thrombus is first walled, from small to large, and even full venous sinus embolism. Because the sagittal sinus receives the superficial venous blood flow in the parietal lobe of the bilateral cerebral hemisphere, the infectious thrombus can spread to the bilateral cortex, forming multiple focal encephalitis or superficial abscess, and causing meningitis, subdural abscess, etc. After timely treatment, if the infection can be controlled, the inflammation stops developing, the thrombus is gradually absorbed, the blood can communicate, the wall thrombus is absorbed faster, and the blood is recovered.

Prevention of superior sagittal sinus thrombophlebitis

Since the advent of antibiotics, this disease has rarely been seen. Occasionally, patients who are sick or not diagnosed with immune function may develop this disease. Gui Shiji (1983) reported one case.

1, the diet should be light and juicy, easy to digest and nutritious, eat spicy, fatty things, such as pepper, pepper, garlic, pepper and so on.

2, often eat a lot of fresh fruits, vegetables, raw nuts, plant seeds, soy products and whole grain food to meet the body's needs for various nutrients.

Complications of superior sagittal sinus thrombophlebitis Complications osteomyelitis aponeurosis subdural abscess epidural abscess edema brain abscess

1. The disease is often a complication of acute frontal sinusitis, acute frontal osteomyelitis, subarachnoid abscess or frontal traumatic trauma and epidural abscess.

2. The brain abscess associated with superior sagittal sinus thrombophlebitis is superficial, and can be puncture drainage by CT scan. Those with cerebral edema can use high-permeability and intracranial pressure.

Superior sagittal sinus thrombosis venous symptoms Common symptoms Nausea and vomiting Night sweats Burn wounds ...

In addition to the primary nasal symptoms, the patient has chills, fever, night sweats, and headache, vomiting and other clinical manifestations of meningeal irritation and sepsis, edema and tenderness may occur in the middle of the head, and patients may have a paroxysmal alternating Local epilepsy, followed by hemiplegia and abducens nerve paralysis, called the superior sagittal sinus syndrome, with the expansion of the lesion, hemiplegia can be extended from the lower extremities to the upper limbs, and severe cases may have symptoms such as coma and aphasia.

Superior sagittal sinus thrombophlebitis is easily overlooked because of its rareness. The following signs can be used as a diagnostic reference:

1. Acute frontal sinusitis accompanied by edema and tenderness in the corresponding area of the superior sagittal sinus.

2. There are multiple abscesses along the bone suture.

3. Sepsis is associated with superior sagittal sinus syndrome.

Examination of superior sagittal sinus thrombophlebitis

1. Blood routine.

2. Lumbar puncture can show increased intracranial pressure and meningeal reaction, blood leukopenia.

3. CT and other imaging examinations.

Diagnosis and differentiation of superior sagittal sinus thrombophlebitis

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory findings.

Differential diagnosis

Different from other diseases that cause meningeal irritation and sepsis, lumbar puncture and imaging examination can be used to diagnose the disease and find out the cause of the disease.
