Retention of fluids in the tissue as side effects.

Edema is caused by the accumulation of aqueous fluids in the tissues of the body from the vascular system. These accumulations can cause swelling of the entire body. As a rule, edema is a concomitant of previous underlying diseases. This either leads to excessive tissue fluid or the removal is disturbed, which accumulates the liquid. For example, heart failure or outflow disorders of the venous blood from the legs may be reasons for the formation of edema. Edema may impair the function of other vessels by applying pressure, which may negatively affect tissue oxygenation. With hyperspectral imaging, the water content of the tissue can be determined parallel to the oxygen saturation. For example, edema can be detected. An example is the recording of the following foot.

Aufnahme eines Fußes mit diabetischer Fußwunde, oben rechts ist der Wassergehalt (TWI) des Gewebes dargestellt. Der rote Bereich zeigt, dass sich dort viel Gewebewasser befindet, also ein Ödem vorhanden ist.

Picture of diabetic foot wound, top right shows the water content (TWI) of the tissue. The red area shows a lot of water, so there is an edema.

With TIVITA® Tissue, fluid deposits in the interstitium can be detected and subsequently treated. Follow-up visits can be used to monitor and tailor lymphoma compression to the appropriate patient for adequate compression. This is especially useful for patients with vascular disease.

Another accumulation of fluid forms a hematoma. The blood comes out of injured vessels and settles in the body tissue or a body cavity. Hematomas are usually caused by external trauma or after surgery, and are usually in the subcutaneous area. In contrast to edema, there is no water deposits. This is clearly differentiated with TIVITA® Tissue, as illustrated by the following example.

Retention of hematoma after surgery

Retention of hematoma after surgery, marked areas show the oxygenation and spectra on the right

The previous figure shows a significant change in the spectral course of the hematoma in contrast to the healthy tissue.
