This not only has diagnostic value, also has great
significance for surgical treatment. Double blocking venography, arteriography
and tumor puncture contrast angiography. Double blocking venography venous
lesions mainly apply to limb muscles of cavernous hemangioma; arteriography
only applies to the main arterial lesions cavernous hemangioma of the limb
muscles, hips and scapular region pulsating cavernous tumor; venography or
arteriovenous contrast tumor is unclear or does not develop the tumor puncture
angiography can not be done automatically, but it can not show the relationship
between the tumor and surrounding blood vessels. Due to limb cavernous hemangioma
majority of venous lesions mainly venography use it is up. Color Doppler
examination is the diagnostic value of the limbs cavernous hemangioma commonly
used inspection method able to understand the extent of the tumor, the size of
the main feeding source to provide a reliable basis for the surgery, and is
economical and practical, no damage, no pain. By preoperative color doppler
checked and confirmed, and confirmed by surgery and pathological examination.
Limb cavernous hemangioma deep position, cryotherapy, laser
therapy, injection hardening agents and radiation therapy are ineffective,
previously only as far as possible through the surgery early complete resection
to cure, resection is not complete and easy to relapse.
Surgery
The principle should save the basic functions of the case,
as far as possible the removal of all diseased tissue. Goidanich the limb deep
hemangiomas are divided into four types: localized, broad-based,
multi-hairstyle, diffuse, guiding significance for the determination of the surgery
the adaptation levy and analysis prognosis. Localized hemangiomas involving
only a muscle or a small range, complete resection rarely relapse; widely and
hairstyle, only for most of the wide range of diseases and dip and important
blood vessels and nerves, surgery and more resection visual impact muscle building review
Resection serious
dysfunction, should be considered at the same time or late reconstruction;
diffuse due to limb involvement more widely associated with limb edema, distal
ischemia, and nutritional disorders, difficult resection surgery, barely
surgery complications easy to relapse; extensive lesions, severe pain, limb
deformities and loss of function significantly, can consider amputation. Use of
a tourniquet during surgery, but does not drive the blood, thus reducing arterial
bleeding, without atrophy collapse of the blood vessels in tumor, clear vision,
because the vein is still filling identifiable tumor blood vessel traffic
branch and convenient ligation, pine tourniquet after bleeding.
A new generation of dual-wavelength the vascular lesions
cynergy therapy
Treatment principle: Shanghai Hua Activtissue Hospital
vascular tumor Branch introduction of dual-wavelength the vascular lesions
cynergy workstation, the workstation world
Workstation principleTwo lasers merge on most tip of Sweden to the same
piece of equipment to be able to continued coherence launch the 585 laser and
the Nd-YAG1064 laser pulsed dye, so that not only can effectively eliminate the
superficial red vessels, but also deep into the dermis internal Clear deep in
the blue blood vessels. In addition, the synergistic effect makes greatly
improve the treatment efficiency, and significantly reduce the side effects.
PDL pulsed dye laser: wavelength 585nm, specifically the
hemoglobin in the blood vessels absorption, through the principle of selective
photothermolysis "vascular coagulation necrosis, which phagocytic system
absorbed and excreted with the lymphatic circulation. because only solidified
in an instant for the hemoglobin for hemangioma, red birthmarks, port wine
stains, scars, small red blood vessels, telangiectasia, and erythema, acne and
other lesions of the International Medical and normal skin without any impact
to date, the pulsed dye laser is the "gold standard . "
Nd-YAG laser : wavelength 1064nm, when the hemoglobin absorb
the energy of the pulsed dye laser, will be formed in an instant methemoglobin.
This micro-coagulation protein dye laser absorption, but the Nd: YAG laser
absorption rate than hemoglobin increased three to five times to produce light
and heat more effectively, so that the coagulation of the blood vessel wall.
Nd: YAG laser on the deep blood vessels, the leg vascular lesions more
effectively.
