Cavernous sinus thrombosis

Introduction to cavernous sinus Cavernous sinus thrombosis is a severe suppurative thrombophlebitis that can be part of systemic sepsis. In addition to the intracranial infection, the disease is mainly caused by the spread of purulent lesions in the eyelids, face, mouth, throat, ear, nose, and paranasal sinuses. It can also be caused by the migration of systemic infectious diseases. In addition, it is related to physical weakness, cardiac insufficiency and trauma. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: optic atrophy

Cause of cavernous sinus thrombosis

In addition to the intracranial infection, the disease is mainly caused by the spread of purulent lesions in the eyelids, face, mouth, throat, ear, nose, and paranasal sinuses. It can also be caused by the migration of systemic infectious diseases. In addition, it is related to physical weakness, cardiac insufficiency and trauma.

The causes of cavernous sinus thrombosis can be divided into infectious and non-infectious.

Infectivity: As the name suggests, it is caused by infections in the scalp, face, sinuses, eyes, pharynx, ears, etc., which spread through the venous return to the cavernous sinus.

Non-infectious: may be due to head and face trauma, tumors or tuberculosis in other parts of the body.

Cavernous sinus thrombosis prevention

1. Pay attention to facial hygiene, correct bad habits such as picking nose and pulling nose.

2. When the nose, lips, and cheeks are swollen, they should be treated promptly, and should not be squeezed or abused.

Cavernous sinus thrombosis Complications optic atrophy

Can cause optic atrophy and so on.

Symptoms of cavernous sinus thrombosis Common symptoms Apathy, nausea, mastoid edema, coma, papilledema, venous reflux, eyeball, sensation, disappearance, paralysis

In addition to the symptoms of systemic poisoning caused by the primary lesion, plus the symptoms caused by metastatic infection of sepsis, especially in the early stage of the disease, paralysis of the contralateral extraocular rectus muscle can be found, which becomes a sign of differential diagnosis.

First, local symptoms

1. Due to venous reflux disorder, eyeball protrusion, bulbar conjunctiva and eyelid edema, congestion, nasal root edema and post-auricular mastoid edema, retinal vein dilation, distortion, retinal edema, hemorrhage, and even mild optic papilla Edema, followed by optic atrophy.

2. Due to the compression of the sinus nerve, the pupil is dilated, direct, indirect photoreaction disappears, extraocular muscle paralysis, fixed eyeball, loss of corneal sensation and pain in the first branch of the trigeminal nerve.

The above symptoms of venous return obstruction and cranial nerve involvement can be rapidly extended to the contralateral side within a few days due to the continued development of the disease.

Second, systemic symptoms

The condition is acute, and the situation is fierce. There is headache, nausea, vomiting, indifferent expression or coma. The edema of the mastoid is caused by the filling and expansion of the nipple. It is a characteristic sign of cavernous sinus thrombosis.

Examination of cavernous sinus thrombosis

1. ENT examination, especially fundus examination.

2. Blood analysis.

Diagnosis and diagnosis of cavernous sinus

diagnosis

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

Differential diagnosis

1. Cellulitis of the cellulitis: often unilateral onset, eyeball fixation is incomplete, the pupil indirect reduction of light response is rare, and systemic symptoms are also mild.

2. Intraorbital tumors: When the tumor is secondary to infection, it is similar to the cavernous sinus thrombosis, but the symptoms of this infection often occur after the eyeball is prominent, and can be identified according to the medical history.
