Negative pressure wound therapy (NPWT) has been proven to be one of the most effective techniques in the treatment of severely infected wounds of various origins and localizations. At the same time, the prospects for its application are constantly expanding. This clinical observation demonstrates the use of NPWT in the treatment of an adult patient hospitalized in severe condition with a picture of extensive post-traumatic infected subgaleal hematoma. The development of a generalized suppurative purulent process was contributed both by the patient’s late request for medical help (18^th day after the injury) and, as a consequence, the lack of primary surgical treatment of the scalp soft tissue injury, as well as the anatomical features of this area. The magnetic resonance tomography as instrumental examination methods played a significant role in the diagnosis of complications in addition to clinical data. Medical tactics was based on the surgical treatment of the infected focus, the application of antibacterial therapy, taking into consideration the isolated microbial flora (Streptococcus pyogenes). To eliminate severe inflammatory changes in the tissues and to reduce the size of the vast subaponeurotic cavity, NPWT technique was applied, which made it possible in short time to prepare a postoperative wound for surgical closure. The early secondary suturing at the final stage of treatment allowed obtaining a good result.

Objective. To study the treatment results of patients with necrotizing fasciitis (NF) of the upper limb. Methods. The authors’ observations of 9 patients with a rare and severe disease: necrotizing fasciitis (NF) of the upper limb have been analyzed. Minor skin lesions in the area of the hand became the entry gate for any infection. The median time prior hospitalization was 4,8±1,8 (M±σ) days. Immediately upon admission, the diagnosis of upper limb NF was established in 5 patients. This was followed by emergency radical surgery. The rest were also urgently operated on, but with a diagnosis of phlegmon of the hand and in insufficient volume. They were diagnosed with NF within the first day and a second operation was performed. In most cases the lesion included tissues of the hand, forearm, and arm. Primary surgery was supplemented by staged necrectomies, the number of which averaged 4,7±1,9 per patient. The complex of intensive treatment included broad-spectrum antibiotics, anticoagulants (enoxaparin 8,000 anti-Xa IU / day). Surgical closure of postnecrectomic wounds was performed using skin plastic operations: plastics with local tissues, autodermoplasty with a split graft. Results. Most of the cases were classified as type II NF (Streptococcus pyogenes or Staphylococcus aureus). In one case, a very rare and extremely severe, NF caused by Pasteurella multocida was observed. No antibiotic-resistant strains were found. Emergency radical operation became the cornerstone of success. The need for staged necrectomy was determined by the formation of secondary necrosis in connection with severe microcirculation disorders. Extensive postnecrectomic wounds were closed after the inflammation subsided with the help of skin plastic operations. The average duration of inpatient treatment was 20,8±6,2 days. There were no lethal outcomes. Conclusion. A complex approach to the treatment of necrotising fasciitis of upper limb allowed getting positive treatment results in all cases.

Endovascular surgery for grade IV chronic ischemia of lower extremities was associated with good immediate results in most cases due to revascularization and organ-sparing interventions for suppurative lesions of the feet. Current endovascular methods allow to perform successful re-operations to restore blood flow in previously repaired arteries and implanted stents with restenosis or thrombosis.

Ollier disease is a rare congenital pathology characterized by the growth of enchondromas in bones, accompanied with their deformities, fractures, and the risk of malignancy. A 39-year-old patient with Ollier disease (acroform with lesions of hands and feet) suffered a rapid development of osteomyelitis of the proximal phalanx of the ring finger after a mosquito bite. The condition localized in the area of enchondroma. Surgical treatment included osteonecrectomy in the phalanx and enchondroma with excision of non-viable surrounding soft tissues, drainage of the surgical wound and the imposition of primary sutures. Morphological analysis confirmed the presence of ectopic embryonic cartilage specific for Ollier disease and the bone destruction. The excised tissues were infiltrated with immune cells and had signs of periosteal chronic inflammation including fibrosis and hyalinosis. These changes, which occurred long before the mosquito bite, became a favorable background for the development of a purulent infection.
