Fat marrow embolism during intramedullary bone endoscopy: an experimental study in sheep.

We present a study designed to investigate whether the intramedullary bone endoscopy (IBE) procedure within the cavity of an intact long bone will create embolic loads on the lungs similar to that of other orthopedic procedures (e.g., stem implantation in total hip arthroplasty [THA]).

Vascular diffusion density and survival of patients with primary lung carcinomas.

Aim: To investigate the clinical significance of tumour vascularisation in operated lung cancer patients.

Materials And Methods: Histological slides obtained from 498 patients with potentially curative operated lung carcinomas in two different institutions of thoracic surgery were immunohistochemically stained with an anti-CD34 antibody and subjected to quantitative image analysis. Syntactic structure analysis measured the absolute and relative features of vessels, including the numerical tumour cells densities relative to their nearest neighbouring vessel.
