[Percutaneous lumbar diskectomy].

The results after percutaneous lumbar discectomy were evaluated in 52 patients with low back pain corresponding to the L5 or S1 root. All patients were examined with a median follow-up time of 14 weeks. The patients were divided in two groups.

Haemostatic activation in patients with head injury with and without simultaneous multiple trauma.

In a prospective study including 16 patients with multiple trauma and head injury and 14 patients with isolated head injury we measured plasma levels of prothrombin fragment 1 and 2 (F1 + 2) and thrombin/antithrombin III complex (TAT) on admission and on days 1, 2, 3, and 7 after the incident. On admission, all patients had values of F1 + 2 and TAT above the reference range. Admission levels of both F1 + 2 and TAT were significantly higher compared with levels on the following days.

Fibrinogen and fibrin derivatives in traumatized patients: relation to injury severity and posttraumatic pulmonary dysfunction.

In a prospective study including 30 traumatized patients, levels of fibrinogen, fibrinopeptide A (FpA), fibrin monomers (FM) and fibrin degradation products (FbDP) were measured on admission and on days 1, 2, 3 and 7 after the incident. High levels of FpA, FM and FbDP were observed immediately after the trauma. Fibrinogen levels increased during the first 7 posttraumatic days whereas FpA and FM decreased.
