Laryngeal hemangioma

Introduction

Introduction to laryngeal hemangioma Laryngeal hemangioma is rare. Divided into two types of capillary hemangioma and cavernous hemangioma, the former is more common. Capillary hemangioma consists of a group of thin-walled blood vessels with a small amount of connective tissue; cavernous hemangioma consists of sinusoidal vessels, soft as a sponge, dark red, without pedicles and diffused under the mucosa, mostly in infants and young children . There are many symptoms of laryngeal hemangioma. If there is damage, it can cause different degrees of bleeding. It occurs in the vicinity of the vocal cords. Laryngoscopy, capillary hemangioma is red or slightly purple, smooth surface, cavernous hemangioma dark red, uneven surface, can extend to the neck subcutaneous, faint blue purple. If the tumor is larger with hemoptysis, the trachea should be incision, and the tumor should be removed under laryngeal rupture. Frozen, laser, electrocoagulation, etc. can also be used. If the tumor is larger with hemoptysis, the trachea should be incision, and the tumor should be removed under laryngeal rupture. Frozen, laser, electrocoagulation, etc. can also be used. basic knowledge The proportion of illness: 0.23% (the probability of illness in infants and young children is 0.23%) Susceptible people: no specific population Mode of infection: non-infectious Complications: congestive heart failure

Cause

Cause of laryngeal hemangioma

1. Genetic factors

2. During pregnancy, women are exposed to environmental pollution, drug stimulation, and adverse factors cause abnormal growth and expansion of the vascular network within three months of the embryo.

3. Food factors caused by environmental pollution

4, traumatic factors

Pathology: Microscopically observed well-developed monolayer endothelial cells and a small amount of connective tissue as a matrix. There are only a small number of blood cells in the lumen. A confined lobulated mass with clear boundaries, slightly protruding from the surface of the skin, bright red and varying in size. Due to the narrow lumen, it rarely turns white when pressed.

Prevention

Laryngeal hemangioma prevention

Pregnant women should take care to avoid possible environmental or drug irritation.

Complication

Laryngeal hemangioma complications Complications, congestive heart failure

Complications of hemangioma include ulcers, hemorrhage, infection, damage to vital organs, congestive heart failure, and limb deformities caused by skeletal muscle damage. If the hemangioma invades the cervical vertebra, symptoms of nerve root compression, such as pain, upper limb sensation and movement disorder, may occur.

Symptom

Laryngeal hemangioma symptoms common symptoms hoarseness and sore throat

The hoarse voice is referred to as hoarseness, which means that the sound is lost in normal, round and clear sound, and becomes hairy, sand, dumb, and sly. Aphonic means that the vocal cords cannot vibrate when they are pronounced, or the vibrations are poor and no sound can be produced.

The anterior and posterior capsules of the nasal septum are thin, the blood vessels are rich and superficial, and are stimulated by trauma or dry air. The blood vessels are easily ruptured and hemorrhage, so it is called easy bleeding area.

Small area: the septal branch of the anterior and posterior stenosis, the posterior septal artery, the septal branch of the maxillary A and the upper lip A. The plexus is formed in the mucosa and submucosa of the anterior and posterior part of the nasal septum, sometimes with the nose. The septal branch of the artery is added, 90% of the snivel occurs here, so it is called the easy bleeding area! Difficulty in breathing, the patient feels that the air is insufficient, the breathing is laborious, and the objective is that the breathing activity is strong. The nose flaps, the purpura, the sitting breathing, and the assisted breathing muscles also participate in activities, and may have abnormal frequency, rhythm, and depth of breathing.

Examine

Examination of laryngeal hemangioma

1. X-ray examination: the lesion area is high-density shadow.

2. Ultrasound exploration: B-mode ultrasound shows irregular shape of the lesion, the boundary is unclear, the interval and the wall can be used as an echo interface, generally showing how many internal echoes of different strengths and weaknesses, and having compressibility. Ultrasound also showed tumor invasion range and depth, and Doppler ultrasound showed diffuse color flow and fast-flowing arterial spectrum.

3. CT scan.

4. MRI T1WI lesions showed medium signal, T2WI was high signal, and there were occasional signal streaks in the medium and high signal area, sometimes showing mixed signals or mottled.

Diagnosis

Diagnosis and diagnosis of laryngeal hemangioma

1. Capillary hemangioma: The main symptoms are hoarseness and hemoptysis. Laryngoscopy reveals that the tumor grows in the vocal cords, with or without pedicles, red or light purple, varying in size, and can occur in other parts of the larynx.

2. Cavernous hemangioma: more common in infants and young children, the tumor is small and asymptomatic, a wide range can be extended to the neck under the skin is blue-purple, in severe cases can produce hemoptysis and laryngeal obstruction, and even suffocation. Laryngoscopy revealed that the tumor is as soft as a sponge, diffusely growing in the ventricular zone, the larynx, and the mucous membrane under the skin. It is dark red and the surface is uneven.

3. It is not advisable to perform a biopsy to prevent bleeding.

4. It should be differentiated from varicose veins, vocal cord nodules, hemorrhagic polyps and non-specific granulomas.
