Minimally invasive cardiac procedures have been investigated to reduce the risks associated with open heart surgery. With the assistance of improvements in engineering technologies such as medical imaging, surgical navigation, and robotic devices, more cardiac surgeries can be performed in a minimally invasive fashion. We have surveyed these state-of-the-art engineering technologies and the minimally invasive cardiac procedures that are benefited from these technologies.

Vertebroplasty (VP) and kyphoplasty (KP) are minimally invasive vertebral augmentation procedures for the treatment of fresh vertebral compression fractures (VCFs) associated with osteoporosis, trauma, malignant conditions, hemangiomas, and osteonecrosis. During these procedures, bone cement (e.g., polymethylmethacrylate) is percutaneously injected into the vertebral body. Systematic reviews of both procedures have shown significantly improved back pain and quality of life compared to conservative therapy. ⋯ The evidence for increased risk of adjacent level fracture after these procedures compared to conservative treatment is inconclusive. When performed by a well-trained practitioner in appropriately selected patients, vertebroplasty and kyphoplasty are both safe and effective treatments for fresh vertebral compression fractures. Results from ongoing randomized controlled trials will provide further detailed information about both procedures in the future.

In the clinical office, during surgical planning, or in the operating room, neurosurgeons have been surrounded by the digital world either recreating old tools or introducing new ones. Technological refinements, chiefly based on the use of computer systems, have altered the modus operandi for neurosurgery. In the emergency room or in the office, patient data are entered, digitally dictated, or gathered from electronic medical records. ⋯ Mathematical models can dictate how a lesion may recur as well as how often a particular patient should be followed. Finally, virtual reality is being developed as a training tool for residents and surgeons by preoperatively simulating complex surgical scenarios. Altogether, computerization at each level of patient care has been affected by digital technology to help enhance the safety of procedures and thereby improve outcomes of patients undergoing neurosurgical procedures.

Necrotizing soft tissue infections (NSTIs) are aggressive severe soft tissue infection that cause rapid and widespread infection and necrosis of the skin and soft tissues and are highly lethal. NSTIs include necrotizing cellulitis, adipositis, fasciitis and myositis/myonecrosis and have significant potential for extensive soft tissue and limb loss. Early diagnosis and treatment of NSTIs remains the cornerstone of therapy. ⋯ Mortality rate has decreased from 25-50% in past years, to 10-16% in recent years with aggressive surgical and medical management. Additional innovative strategies for the treatment of NSTIs, including intravenous immuno-globulin G (IVIG), hyperbaric oxygen, and vacuum-assisted closure, do not yet have definitive evidence of efficacy, but may be considered in patients at high risk of death. A comprehensive knowledge of the pathophysiology, diagnostic features, causative microbial pathogens, and treatment strategies (including surgical debridement and antimicrobial therapy) is required for successful management of NSTIs.

Acute limb ischemia (ALI) is one of the most common vascular emergencies and characterized by sudden worsening of limb perfusion mainly caused by embolization of thrombotic masses or acute graft occlusion. It is a serious condition with potential thread to limb viability accompanied by significant mortality, morbidity and costs. This article provides an overview of etiology, classification and treatment options of ALI ischemia with special focus on the issue of postreperfusion syndrome. The concept of reperfusion injury following limb ischemia and a system for controlled limb reperfusion to offset postreperfusion synsrome is described in detail.
