RESUMO
Hemangiopericytoma (HP) is a rare tumoral neoplasm of the soft tissues. Here, we report a case of HP that appeared in a young woman in a very uncommon location (perianal). Initially it was considered as a perianal abscess: arteriography, CT-scan and, eventually, histological studies, confirmed the diagnosis of HP. The tumoral mass was first embolized and thereafter was resected through a double approach (abdominal and perineal). One and a half years after surgery, the patient remains asymptomatic.

Authors present their experience (32 patients affected by a traumatic femoropopliteal injury) with vascular traumatisms at the lower limb. Causes, treatment and successful results with the new technics and the early clinical management to the patients are commented.

After a period of time of 5 years, we made a review of all the patients registered at our Center. Eight cases of closed traumatism at the scapulohumeral belt, with vascular injury associated (0.2% of all closed traumatisms at this level registered in our center during this time) were reported. Six patients presented also an osteoarticular injury associated. Three different vascular injuries were showed: three cases of complete arterial section, two arterial contusions and a partial arterial section. From the two cases without osteoarticular injuries, one of them showed a complete section and the other presented an arterial contusion. Polytraumatic patients showed multiple osteoarticular injuries. We registered one fracture-luxation at the shoulder, 3 diafisaric humeral fractures, one humeral neck fracture, one clavicle fracture, one fracture-luxation at the cervical column and one simple luxation of the shoulder.

High plasma fibrinogen appears to be an important risk factor for the development of atherosclerosis. The aim of our study was to measure fibrinogen and fibrin degradation products (D-dimer), interleukin-6 tissue plasminogen activator, plasminogen activator inhibitor-1 and urokinase-type plasminogen activator in the plasma and arterial walls of 45 patients who had arterial surgery between April 1993 and November 1995. The arterial specimens were also examined by immunohistochemists for these same factors. The serum fibrinogen and fibrin degradation products were high in all patients, and fibrinolysis was depressed. Few leukocytes were seen in the arterial walls, which had poor fibrinolytic activity. Plasminogen-activator inhibitor activity in the wall was also reduced in the affected arterial walls. The abdominal aorta appeared to have the highest levels of fibrinogen and this may be related to its ability to form aneurysms. Fibrinogen may play an important role in the progression of atherosclerotic disease.
