A virtual reality based navigation system for endovascular surgery.

Endovascular surgery provides a minimally invasive solution for the treatment of aortic aneurysms. Fluoroscopic guidance involves X-rays exposure and loss of space information. We have developed a navigation system allowing real-time visualisation of the endovascular tools in a 3D model of the vessels without any radiation exposure.

[Endovascular aortic balloon catheter occlusion for severe renal trauma].

Control of the renal vascular pedicle in a context of severe renal trauma in a haemodynamically unstable patient is difficult due to the large retroperitoneal haematoma. Laparotomy in these exsanguinated patients is associated with a risk of cardiac arrest due to hypovolaemia. The authors describe an endovascular aortic balloon catheter occlusion technique prior to laparotomy for haemostasis nephrectomy in a haemodynamically unstable patient presenting an abdominal compartment syndrome.

[Malignant carotid paraganglioma. A case report].

The most common sites of paragangliomas occurring in the head and neck region are the carotid body and vagal glomus. The clinical course of carotid body paragangliomas is characterized by two modes of development: locoregional growth and distant metastatic dissemination. Few cases of malignant carotid body paraganglioma have been reported in the literature.

Critical hand ischemia after angioaccess surgery: diagnosis and treatment.

Severe hand ischemia is an uncommon complication of angioaccess surgery. Prompt recognition is necessary to prevent finger necrosis and permanent nerve damage. Treatment should relieve symptoms without compromising dialysis access.
