[Radiofrequency ablation of malignant liver tumors: use of a volumetric necrosis-tumor ratio for local control].
Sufficient safety margins are essential for preventing local tumor recurrence after radiofrequency ablation RFA of malignant liver tumors. The aim was to determine the initial tumor volume, ablation necrosis volume, and the necrosis-tumor quotient in order to compare these parameters with the rate of local control during follow-up. ⋯ The volumetric necrosis/tumor quotient NTQ makes it possible to predict the local outcome and can be used for the planning of additional therapy.

To study the influence of (Modic) signal alterations (SA) of the cartilage endplate (CEP) of vertebrae L3-S1 on the outcome of an in-patient minimally invasive treatment (MIT) using epidural injections on patients with lumbar disc herniation (LDH). ⋯ 1. Lumbar disc herniation is clearly associated with the prevalence of (Modic) signal alterations. 2. Extensive signal alterations tend to correlate with a negative outcome of an MIT using epidural injections. 3. Such SA in the central portion of the upper CEP correlate significantly with a negative treatment result. 4. The central portion of the upper CEP being extensively affected by (Modic) SA is a negative predictor for the success of a minimally invasive pain therapy.

To retrospectively evaluate procedural success and patency after endovascular treatment of acute dysfunctional hemodialysis fistulas and grafts in a non-preselected patient cohort. ⋯ Endovascular treatment of acute dysfunctional hemodialysis fistulas and grafts is effective in restoring the patency for hemodialysis.

Evaluation of the prognostic value of morphological cardiac parameters in patients with suspected and incidental acute pulmonary embolism (PE) using multidetector-row chest CT (MSCT). ⋯ The RV (D) and RV (D)/LV (D) ratio were suitable for identifying patients with acute cor pulmonale and for benign short-term prognosis. Further studies should prospectively address the combined use of CT-morphological and clinical parameters for the prediction of patient outcome.
