Hemangiomas consist of a large number of proliferating blood vessels. The etiology of hemangioma includes early embryo, which is caused by abnormal development of primitive blood vessels. Primitive blood vessel is a kind of pipeline composed of endothelial cells, which form a dense network in the middle of matrix. How is hemangioma formed? The following is what I arranged. Welcome to reading.
How is hemangioma formed? Hemangioma is a congenital benign tumor or vascular malformation, which is more common at birth or shortly after birth. It originated from the remaining embryonic vascular cells, and the active endothelioid bacteria invaded the adjacent tissues to form endothelial splines, which were managed to form hemangioma and then connected with the left blood vessel. The blood vessels in the tumor are self-contained and not connected with the surrounding blood vessels. Hemangiomas in oral and maxillofacial region account for 60% of all hemangiomas, most of which occur in facial panel, subcutaneous tissue and oral mucosa, such as tongue, lips and floor of mouth, and a few occur in jaw or deep tissue.
In the process of human embryo development, especially in the early stage of vascular tissue differentiation, due to the small-scale dislocation of its control gene fragments, the tissue differentiation of its specific parts is abnormal and it develops into hemangioma. In the early embryonic period from August to 65438+February, the embryonic tissue was mechanically damaged, and regional tissue bleeding caused some hematopoietic stem cells to distribute to other embryonic characteristic cells, and some of them differentiated into vascular-like tissues, eventually forming hemangioma.
The main causes of hemangioma
1, genetic factors: the probability of hemangioma formation is generally small! During pregnancy, women were exposed to environmental pollution, drugs and adverse factors, which led to abnormal proliferation and expansion of vascular network in embryos within three months.
2. Traumatic factors: Under normal circumstances, if trauma is handled properly, it will not cause hemangioma on the panel, but if the wound is not bandaged in time, wound infection or scar hyperplasia will cause hemangioma on the panel.
3. Embryonic factors: Some scholars believe that the reason of early hemangioma is that the embryonic tissue suffered mechanical damage at 8~ 12 weeks of early embryo, and local tissue bleeding caused some hematopoietic stem cells to distribute to other embryonic characteristic cells, and some differentiated into vascular-like tissues, eventually forming hemangioma.
Classification of hemangioma 1. capillary angioma
The tumor is composed of a large number of interlaced and dilated capillaries. It is characterized by bright red or purple spots. Flush with the surface of the panel or slightly raised, with clear boundaries, irregular shapes and different sizes. Press the tumor with your finger, and the color will fade; After the pressure is released, the color returns.
2. Cavernous hemangioma
The tumor consists of an enlarged vascular lumen and a blood sinus lined with endothelial cells. Blood sinuses are different in size, like sponge-like structure, filled with venous blood and communicate with each other. It is a soft lump with no conscious symptoms and slow growth. When the head is low, the tumor expands due to congestion, and after it returns to normal, the lump returns to its original state. A superficial tumor with a blue-purple surface or mucosa. Dark, normal complexion. When palpated, the lump was soft, with unclear boundary and no tenderness. The mass will shrink during extrusion, and will return to its original size after pressure is released.
3. Tendinous hemangioma
Mainly formed by dilated arteriovenous anastomosis. The tumor is beaded or earthworm-shaped. Hearing has a sense of pulsation and tremor, auscultation has a blowing sound. If all the blood supply arteries are closed, the above pulsation and murmur will disappear.
Clinical treatment of hemangioma 1. Ultrasound minimally invasive therapy.
It is a new technology developed on the basis of interventional therapy and arteriovenous catheter technology. It is not as painful and expensive as interventional therapy, and it is very mature at present. Compared with other technologies, it does not produce radiation and radioactive substances, and does not use hormones, isotopes and chemotherapy drugs. This technique is suitable for the treatment of hemangioma such as capillary hemangioma, cavernous hemangioma, mixed hemangioma and lymphatic hemangioma, especially for infantile hemangioma, and has good therapeutic effect.
Principles of treatment
Under the guidance of three-dimensional color Doppler ultrasound positioning, the technique is to puncture and insert the nutrient branch lumen and the swelling part with abnormal structure through a microcatheter, and use ultrasonic ablation technology in the blood vessel to shrink the blood supply branch vessel wall, narrow the lumen, reduce the blood supply of the tumor, and balance the blood supply and reflux of the tumor, thus achieving the purpose of treatment. It is a safe, effective and minimally invasive new minimally invasive technology.
technical characteristics
During the treatment, the operation is completely under the guidance of imaging equipment, and no radiation and radioactive substances are generated. It can be used for stereotactic treatment of visceral hemangioma except intracranial hemangioma and spinal hemangioma, which is suitable for a wide range of people, and infants born more than one month can generally receive treatment. Minimally invasive, no recurrence, less bleeding, combined with the unique hemangioma treatment drugs in our hospital, the treatment effect is excellent, the time is short, no recurrence, no surgery, no scars and beautiful appearance.
technical superiority
1 targeted positioning and precise treatment: targeted positioning is performed on the diseased tissues of hemangioma with precision instruments, so that the whole treatment process can be controlled, and the damage and destruction to normal panel tissues other than hemangioma are avoided during the treatment process, and the treatment is intuitive and accurate.
2 Simple operation, safety and reassurance: This technique is a minimally invasive technique for the treatment of hemangioma. The operation method is simple and convenient, which can make the diseased tissue of hemangioma organize, shrink and disappear until it is closed, avoiding the shortcoming of slow recovery of traditional surgery, making children suffer less and parents feel more at ease.
3 Minimally invasive therapy, the curative effect is remarkable: the brand-new minimally invasive therapy has broken through the therapeutic effect that traditional therapy has not achieved and avoided the formation of scars. Years of clinical treatment data show that ultrasound minimally invasive interventional therapy is effective and recognized and trusted by patients.
4. Fast recovery and low cost: the treatment adopts minimally invasive technology, which has little trauma, not only can quickly cure hemangioma, but also shorten the recovery time of patients and greatly reduce the hospitalization and treatment costs of patients.
5. Thorough treatment to avoid recurrence: traditional treatment is easy to relapse if it treats the symptoms rather than the root cause. Ultrasound minimally invasive treatment is superior to traditional treatment, which can prevent postoperative recurrence and avoid complications.
2. High frequency electrocoagulation method
Under the orientation of three-dimensional ultrasound, the advanced high-frequency electrocoagulation therapeutic instrument and catheter needle are used to directly act on the tumor, which causes high fever in the tumor, emulsification, coagulation and contraction of the blood vessel wall, and the tumor gradually shrinks, and the deformed blood vessel loses its ability to re-expand.
This treatment technique does not damage normal tissues and cells and avoids scar formation after treatment. It is suitable for cavernous hemangioma, capillary lymphangioma, tendinous hemangioma and multiple lymphoangiolipoma. The course of treatment is short and the effect is good, which has been unanimously recognized by the majority of hemangioma patients. Adapt to symptoms
Infantile hemangioma, strawberry hemangioma, deep tendon hemangioma, tendinous hemangioma, lymphatic hemangioma, cavernous hemangioma, etc. technical superiority
The treatment is rapid, efficient and unique.
High-frequency electrocoagulation minimally invasive treatment can quickly block the growth gene of hemangioma, target the elastic fibers and collagen fibers in the cell membrane and surrounding tissues of hemangioma, and promote the emulsification, coagulation and contraction of blood vessel wall until it disappears. The treatment method is unique and the effect is remarkable.
The curative effect is exact and there is no recurrence.
The common treatment of hemangioma takes a long time and is easy to recur. Adopting "high frequency electrocoagulation minimally invasive treatment" can make patients achieve ideal therapeutic effect in a short time and effectively avoid recurrence.
3. Compound narrow-spectrum photodynamic therapy
Principles of treatment
Under the control of a microcomputer, a semiconductor narrow-spectrum light source with a wavelength of 400nm-650nm is used, and different spectral wavelengths are selected for different photosensitizers within the wavelength range of the light source. It selectively penetrates the panel without damaging normal blood vessels and panel tissues, and directly acts on the diseased tissues by utilizing the tissue structure of port wine nevus located in the superficial dermis of the panel, so that the abnormal capillaries growing in port wine nevus collapse instantly, thus achieving the purpose of rapid treatment of diseases.
technical characteristics
In the course of treatment, a therapeutic light source consisting of at least two semiconductor narrow-spectrum light sources with different wavelengths is adopted, and a special narrow-spectrum light source substrate is designed, so that different narrow-band composite spectra are formed by making full use of the excellent wavelength selectivity of the semiconductor narrow-spectrum light sources to meet the best spectral requirements of different photosensitizers for photodynamic therapy drugs and achieve the best therapeutic effect.
