Breast Reconstruction with Aeroform Tissue Expander

It seems like all the latest breast reconstruction techniques like Neopec come from Australia. Now the Australians have come up with a rapid way to expand chest skin after breast cancer mastectomy to allow placement of a breast implant and thereby reconstruct the breast (see my blog Reconstruction After Breast Cancer Surgery). Usually a saline balloon or expander is surgically placed and the surgeon then progressively fills it with salt water that is injected on a weekly basis to stretch the skin. This can take up to 6 months. Now they have devised an expander that contains a cylinder of compressed carbon dioxide gas. The patient controls the release of the gas into the expander with a handheld remote control and slowly expands on a daily basis.

Preliminary data reveal that using the Aeroform Tissue Expander the expansion can be completed in 17 days instead of 6 months. Enrollment in FDA clinical trials have begun in the US and the manufacturer is predicting a 2014 FDA clearance for general use.

Woman's Body Swallows Breast Implant

A report from Johns Hopkins University in the December 2011 New England Journal of Medicine describes the swallowing of a breast implant into a woman's chest cavity. The patient had reconstruction of both breasts after mastectomy for breast cancer. She subsequently had minimally invasive heart surgery via the right mastectomy scar. Some time later while partaking in a Pilates class the right implant was swallowed by her body during a stretching exercise. The intact implant squeezed through a small hole between her ribs left from the heart surgery and ended up on top of her right diaphragm. It must have been scary to look down and see the implant disappear into her chest.

The implant was retrieved, the hole in the chest was closed with a mesh patch and the implant was put back in its original position. Now I assume she is back doing Pilates. This is one thing you don't see everyday.

New Discovery Could Make Breast Implants Obsolete

Earth shattering news out of Australia this week could have monumental effects on breast surgery, both reconstruction after breast cancer and enlargement for cosmetic reasons. The technique discovered in Australia is called Neopec. So far the process has only been performed in pigs and was so successful that human trials are scheduled too begin in early 2010. The pigs grew new breasts in 6 weeks. The surgeon places a scaffold or shell of biodegradable material in the breast, redirects a small blood vessel from the arm into the shell, places a small amount of the patient's own fat inside the shell, and a dissolvable gel called Myogel is also placed in the shell. The Myogel and blood flow from the transferred artery stimulate the fat to grow until it fills the shell and therefore takes the shape of the shell. This is a direct finding from stem cell research. After that the biodegradable shell is dissolved by the body. In the future the shell may come with its own artificial blood vessel.
