[Traumatic dissection of the internal carotid artery following whiplash injury. Diagnostic workup and therapy of an often overlooked but potentially dangerous additional vascular lesion]. / Traumatische Dissektion der A. carotis interna nach HWS-Beschleunigungstrauma. Diagnostik und Therapie einer häufig übersehenen aber potenziell gefährlichen Begleitverletzung.

We report on the case of a 33-year-old male patient who was brought to the emergency room of our hospital after suffering a high-energy trauma due to an automobile accident. Besides a scaphoid fracture there were no signs of any neurological deficits. After several hours without clinical symptoms the patient developed dysarthria as the first manifestation of local cerebral ischemia based on a traumatic dissection of the internal carotid artery. Under systemic high-dose heparin therapy, fast and complete remission of all neurological disorders could be achieved. In the course of time a dissecting aneurysm developed. Temporary anticoagulation with phenprocoumon was started in the meantime and no further complications have appeared up to now. Besides presenting this absorbing case, this article highlights the diagnostic and therapeutic regime in cases of a traumatic dissection of supra-aortal arteries for rapid and adequate management of this rare but potentially dangerous complication.

[CT-findings in penetrating captive bolt injuries to the head and brain: analysis of the trauma-related CT-findings and review of the literature]. / CT-Befunde bei penetrierenden Kopfverletzungen durch Bolzenschussgeräte--Analyse der verletzungsspezifischen CT-Befunde und eine Übersicht über die relevante Literatur.

Penetrating gunshot injuries to the head and brain are rare in Germany and the rest of Western Europe. Due to the small number of cases over here no consistent diagnostic and therapeutic standards exist in this respect. Thus these kinds of injuries present a great challenge to the attending physicians. Most of these violations are a result of a suicidal attempt or an accident. Beside violations by firearms also penetrating injuries to the head and brain due to captive bolt devices, as used in slaughtery business for the "humane" killing of animals, occur from time to time. The impact on the head differs from that caused by firearms because no projectile is leaving the barrel and the used bolt, as a fix part of the device, does not remain in the affected tissue. That implies characteristic results within the radiological imaging that might be pathbreaking for the further treatment, because the origin of such a head injury is often unknown during primary care. Consequently the knowledge of these specific findings is central to the radiologist to make the appropriate diagnosis. Based on some clinical examples the trauma-related CT-findings are introduced and a short overview of the relevant literature is also given.

[Marjolin's ulcer: malignant transformation of a crural ulcer due to posttraumatic chronic osteomyelitis]. / Das Marjolin-Ulkus : Maligne Transformation eines Ulcus cruris auf dem Boden einer posttraumatischen chronischen Osteomyelitis.

We report on the case of an 81-year-old female patient who developed a squamous cell carcinoma in a long-lasting therapy-resistant crural ulcer of the lower leg due to posttraumatic chronic osteomyelitis. Eventually the lower leg had to be amputated because of massive destruction of soft tissue and the tibia bone. Based on the desolate wound conditions plastic reconstruction by a pivoted muscle flap and surgical covering with mesh graft plastic was also necessary.The amputation stump had completely healed 6 months after surgery and the patient is fitted with an artificial limb ensuring independent mobility even outside the home. Up to the present there is no evidence of any tumor recurrence or progression.
