Renal vein occlusion: diagnosis and treatment.

Renal vein occlusion in adults is usually a result of vein thrombosis, which is frequently associated with the nephrotic syndrome. The anatomy of renal vascularization is of primary importance for understanding its pathophysiological responses and the clinical and diagnostic presentation of patients with this condition. The reaction of the kidney to its vein occlusion is determined by the balance between the acuteness of the disease, extent of the development of collateral circulation, involvement of one or both kidneys and the origin of the underlying disease.

Endovascular treatment of an open cervical fracture with carotid artery tear.

The dilemma of how to treat penetrating wound injuries to the neck, which involve a combination of a common carotid artery rupture and a cervical spinal fracture, is presented in this case report.

Isolated complete popliteal artery rupture associated with knee dislocation. Case reports.

Complete dislocation of the knee is a rare injury, and is frequently associated with injuries to other structures in the popliteal fossa. Prompt recognition of associated popliteal artery disruption and early revascularization is paramount for successful and functional results. The necessity for emergency vascular reconstruction markedly complicates an already difficult orthopaedic problem.

Delayed carotid artery rupture in advanced cervical cancer--a dilemma in emergency management.

Carotid artery rupture in the setting of advanced carcinoma of the head and neck constitutes a surgical emergency. This report details three such patients, two of whom presented with profuse bleeding, the other with imminent rupture. Notably, our first patient ruptured 27 years after having had radiotherapy for carcinoma of the larynx.
