What is Surgical Removal of Dead Tissue?

After a serious injury or infection, it is common for tissue to die and fall off the body. However, when tissues die on a large scale, it presents a very real danger to the health of the dog. These gangrenous or necrotic tissues will almost always require excision or amputation in order to prevent sepsis and eventual death. This process is known as 'debridement' and usually takes the form of cutting dead flesh away from an existing wound.

Surgical Removal of Dead Tissue Procedure in Dogs

The main method of surgically removing dead tissue is to use a scalpel or similar implement to manually cut it from the body. Sometimes, a mechanical 'scouring' device can be used to strip it away, but this method is less common due to its high tendency to damage healthy tissue. The first step the surgeon will take is to sedate the dog with a general anesthetic, which will allow the vet to better examine the wound and determine exactly where their cuts need to be placed. The next step is to incrementally remove the dead tissue, taking care not to cut deeply into the healthy tissue that surrounds it. After the dead flesh has been removed, the wound will be cleaned and covered with a dressing in order to heal properly. 

Efficacy of Surgical Removal of Dead Tissue in Dogs

Unless an infection has already spread from gangrenous tissue into the rest of the body, the effects of removing dead tissue will be instant. The wound will now be able to heal properly, instead of having its progress blocked by the dead matter. Although scarring may be an issue afterwards, the effects of successfully excising gangrenous flesh will be permanent as a major vector for infection is removed from the body. 

That said, there are alternative methods for removing dead tissue that are not quite as invasive (though somewhat less reliable). The first is to simply cover the wound and give the body an opportunity to break it down naturally (although this can simply give the rot time to spread). The second method is to use man-made chemicals to burn the dead flesh away. Although quite effective, this method does carry a substantial risk of harming healthy tissue. The third alternative is to use naturally occurring enzymes to digest the dead flesh whilst it is still in the wound - though this can take quite some time.

Surgical Removal of Dead Tissue Recovery in Dogs

Following the surgery, it is important for owners to provide a high quality of aftercare, as the wound their pet just had debrided will have increased considerably in surface area. This means that the dog's movements may have to be restricted via even less exercise and the use of an 'E-collar' to prevent them from introducing more bacteria into the wound with their mouth. Painkillers will also be required to stop them from suffering unneeded discomfort until the healing process is complete. The vet may also want to schedule a series of checkups after the surgery to make sure that no further complications have arisen. The total healing time for the surgical wound itself may be just over a month, depending on the size and depth of the area affected, and the age and general health of the dog involved.

Cost of Surgical Removal of Dead Tissue in Dogs

The cost of wound debridement depends on several factors including the severity of the base injury and the nature of the dog's medical history. More extensive surgery will command a higher price, as more expertise and finesse is required in order to avoid complications. Typically, the base cost will be over $600 but can be expected to not exceed $1,000.

Dog Surgical Removal of Dead Tissue Considerations

As always, owners of older dogs or dogs with a history of heart and breathing problems should be wary of any surgery that requires the use of general anesthesia. That said, while there are alternatives available, direct surgical removal of dead tissue is one of the fastest and most reliable ways to rectify the problem. 

Surgical Removal of Dead Tissue Prevention in Dogs

It is virtually impossible to predict and avoid most common injuries, as they are more or less an inevitable part of any active dog's life. That said, making sure to keep cuts and other open wounds clean and free of dirt will prevent a dog from developing necrotic tissue that requires removal. This does not just apply to surgical wounds, but also to everyday cuts and scratches.

Would an alternative to debridement possibly be safer for a geriatric dog? I am so worried about our girl going through surgery, but I want her better. I also feel we may be battling recurring infection if we don't at least do a lift surgery. Our little one (17 years old) has had an infection of the vaginal area. She has lost a bit of weight over the last year (switched her to real food) and se is spayed. The vet discovered that there is a hood of skin causing moisture and possibly urine to collect in the area. The vet also discovered necrotic tissue. The recommendation is surgery to debride and lift/tuck the skin. They sedated her to clean the area at a lower than usual does due to her age. She came home ad was out cold and disoriented the little time she was awake for the rest of the evening. I am so afraid she may not handle surgery well, but also am afraid of what will happen if we don't. To compound things, we are moving in 1.5 weeks. If surgery is the best option, I believe we will wait until we get to our new location. that puts the surgery out at least 3 weeks.

I understand your concerns, especially in a girl the age of Jennie, but I cannot think of an alternative especially if your Veterinarian found some necrotic tissue; I wouldn’t wait the three weeks for you to settle into your new home but get the surgery done sooner, assuming that her blood tests come back well and she is otherwise in good general health.

My dog got a broken leg and femur due to a car running her over. I took her to the vet immediately this happen on Thursday morning, he charge over a $1600 and told him I would try to raise the money left him a down payment of $100 and he kept my dog. Went back Friday to see her and saw that she still had small pieces of rocks around wound and by this time donations where being called in. On Saturday I went to see her foot look swollen and didn't wanted to check wound because it look swollen ( doctor was not there so could not ask about her health) Sunday vet was close went monday morning to tell vet that the money was raise for surgery but he gave me the bad news the my dog had gangrene and her leg had to be amputated, I then ask to try to save it and he said he was going to do his best. My dog had surgery until 5-6 pm they save the leg.
Is it true that gangrene can come back???
Did my dog get gangrene because vet didn't clean the wound good??

Or is this normal???

Took dog right after accident.
