Traumatic nonanastomotic axilloprofundal PTFE-bypass rupture: a case report.

A 76-year-old male patient was admitted to our emergency department with painful swelling of the right lateral chest after a fall. Imaging revealed a hematoma, secondary to rupture of a synthetic axilloprofundal bypass. In an emergency surgical procedure, the spelled hematoma was evacuated and the graft legs were successfully ligated.

Relevance of Ki-67 antigen expression and K-ras mutation in colorectal liver metastases.

Aims: The liver is a frequent site of metastases from colorectal cancer. While these lesions are potentially amenable to surgical resection, they are usually very aggressive, and recurrence is frequent. Mutations of the proto-oncogene K- ras are thought to impart a strong growth signal to tumour cells and are closely associated with the development of malignancies of the colon and rectum.
