Cryosurgery (cryotherapy) is the local application of extreme cold for a controlled destruction or removal of abnormal or diseased tissue. In the past years innovations in the methods of application of the cryogen have made cryosurgery a preferred surgical treatment option for veterinarians to use on their patient animals. More portable, easy to use hand-held devices, such as the CryoIQ®, were developed to give the veterinarian the possibility to treat skin lesions with accuracy and efficacy, either in their office or in the field.
The freezing of the tissue by the direct application of the cryogen makes the procedure safe, efficient and fast. The freezing temperature will destroy cells in the target tissue, the accuracy will avoid destruction of adjacent healthy tissue and a powerful method of application will allow the veterinarian a rapid penetration of the targeted lesion.
The compact, portable CryoIQ® hand-held device uses Nitrous Oxide cartridges as a cryogen with a freezing temperature of -89°C/-128° F and once punctured the Nitrous Oxide is delivered with a 725psi/ 50 bar pressure to the lesion which allows the veterinarian a fast and effective treatment.
The CryoIQ® gives the veterinarian the ability to control the width and depth of a skin lesion treatment using various types of applicators and for every 4 seconds of freeze the skin will be penetrated 1mm in depth, to a maximum of 5-6mm.
The CryoIQ® offers the feature of using 2 different freezing methods which enhances the treatment options for the veterinarian:
- Liquid Spray Freezing:
- Provides millimeter precision freezing to the treatment site through micro capillaries.
- Contact Freezing:
- Closed tip applicators are cooled off by the cryogen before placing onto the lesion for a hassle-free contact freezing.
Cryosurgery has been used by veterinarians are to in treatment procedures for, but not limited to:
- Eyelid tumors and masses
- Tail and tail- base tumors
- Tongue tumors
- Paw or pad mast cell tumors
- Skin tags
- Tumors in the mouth, ear
- Peri-anal carcinomas and anal gland tumors
Advantages of veterinary cryosurgery:
- Inexpensive procedure because anesthesia and sterile preparation not necessary (out-patient procedure).
- Fast and efficient treatment, less time needed for the veterinarian in a busy office.
- Minimal to none pre-or post- operative care.
- No general anesthesia needed in the majority of the treatments.
- The tissue and surrounding blood vessels freeze which causes its own numbing, making it practically painless and bloodless.
- Lower risks of complication, less pain and quicker healing.
