Constrictions or occlusions of veins can lead to painful swelling of the dependent extremity (leg or arm). If circumscribed constrictions or fresh occlusions can be detected, interventional reopening can be considered. Access to the vascular system depends on the localization of the findings.

In addition to chronic constrictions caused by expired thromboses (blood clot formation in the vein), we also treat fresh occlusions of the veins, e.g. pelvic vein thromboses.

In the case of blood clots in the pelvic or leg veins(leg or pelvic vein thrombosis), a metal umbrella may be inserted into the inferior vena cava after other treatment options have been considered. If clots detach from the thrombosis, they remain trapped in the umbrella and cannot sponge into the pulmonary vessels. Once the thrombosis has been treated, the umbrella can also be removed from the vessel by our Department within a certain period of time.

Varicose veins of the testicles are a possible cause of swelling in the testicle area and a reason for infertility. These varicose veins can be sclerosed "from the inside" via a puncture in the inguinal vein and the insertion of a catheter (tube) and represent an alternative to surgery.

Over the years, hemodialysis shunts can develop constrictions or occlusions. In many cases, minimally invasive reopening is feasible.

Certain forms of hormone overproduction are caused by a pathological enlargement of the adrenal gland. Some imaging constellations (CT or MRI) make it necessary to take blood samples from the adrenal veins in order to determine which of the adrenal glands is responsible for the overproduction. In order to increase the accuracy of these blood samples, we work closely with the endocrinology department at the MHH and can significantly increase the accuracy during the procedure using a rapid laboratory test.
