The CDU-guided SFA puncture technique was both more effective than CDU-guided CFA access in patients with scarred groins, obesity, or failed CFA punctures and safer, with reduced screen times, radiation doses, and complications.

Colonic stenting in acute large-bowel obstruction is more likely to be successful in shorter, malignant strictures with less angulation distal to the obstruction. Longer benign strictures are less likely to be successful and may be associated with an increased risk of perforation.

The successful use of peripheral nerve blocks was safe and effective as an alternative to sedative/opiate, epidural or general anesthesia in patients undergoing complex angiography and has optimized the use of radiological and anesthetic department resources. This has permitted the frequent radiological treatment of patients with limb-threatening ischemia and reduced delays caused by the difficulty in enlisting the help of anesthetists, often at short notice, from the busy operating lists.

BackgroundThe surgical treatment of bone tumours can result in large peri-operative blood loss, due to their large sizes and hypervascularity. Pre-operative embolisation has been successfully used to downgrade vascularity, thus reducing peri-operative blood loss and its associated complications.MethodsPre-operative embolisation was successfully undertaken on twenty-six patients with a variety of primary and secondary bone tumours.ResultsMean blood loss was 796 mL and we experienced no complications.ConclusionPre-operative arterial embolisation of large, richly vascular bone tumours in anatomically difficult positions, is a safe and effective method of downstaging vascularity and reducing blood loss.

We describe the management of a 30-year-old male with type I neurofibromatosis who required an above-knee amputation for bleeding, infection, swelling, and multiple severe joint instability. Postoperatively, he continued to bleed from the stump site. Angiography revealed multiple small distal bleeding aneurysms. Hemostasis was eventually achieved with standard microcoil embolization.
