Subintimal angioplasty is technically successful in most patients, with few complications. Most procedures provide short-term clinical success and have allowed for successful wound healing and temporary relief of rest pain. However, late arterial patency is poor, with a high rate of symptom recurrence. Many patients will have recurrent pain, and some will require major amputation. Nevertheless, limb-salvage rates are significantly better than arterial patency. Intermediate-term patency is higher than that commonly reported for prosthetic bypass, and despite the lack of durable long-term patency, the procedure offers an additional potentially effective therapeutic option in the treatment of patients with limb-threatening ischemia and femoropopliteal occlusion.

Methods are described for the isolation and identification of aerobic bacteria occurring naturally in the hind-gut of the cockroach Blatta orientalis captured from a number of wild sources, to establish whether or not human pathogens occurred naturally within the gut. During the investigation an organism was frequently found which could not be classified in any described species, and for which we propose the name Escherichia blattae.
