Burned unilateral half-cheek resurfacing techniques.

Postburn cheek deformities are a tragedy for patients and pose a great challenge to surgeons due to a limited number of well-matching donor sites. In cases of unilateral half-cheek deformity, the flap's skin should match the contralateral cheek and the residual skin of the deformed cheek. The skin of a distant flap does not match the facial skin and resembles a patch.

Unilateral cervical burn scar deformity elimination with contralateral cervicothoracic flap--a new approach.

Unilateral postburn cervical deformity is a severe cosmetic and functional defect and a challenging reconstructive problem. Many flaps have been suggested; however, after surgery, operational scars, located along the anterior neck's middle line, and the flap's skin differ from cervical healthy skin. A small flap resembles a patch.

Clinical manifestations and diagnosis of pathological deformity of the internal carotid artery.

Objective: to study clinical and morphological aspects of pathologically deformed pathological deformity of the internal carotid artery.

Methods: the study was based on retrospectively analysing the findings of examination and the outcomes of surgical treatment of 142 patients presenting with an isolated pathological deformity of the internal carotid artery (1СA), who underwent a total of 166 reconstructive operations.

Results: more than half (58%) of the patients were operated on for 1С A kinking, 27% for coiling and only 15% were found to have C- and S-shape tortuosity.

The elimination of postburn nasal contracture in children with trapeze-flap plasty.

One consequence of a facial burn is nasal contracture. In pediatric patients, scar tension presents a particular problem because of facial growth. The forehead and nasal scar contraction deform the nose dorsum, especially between the eyes.

Post-burn microstomia: anatomy and elimination with trapeze-flap plasty.

Perioral contractures after burn (microstomia) is a common consequence of facial burns. A small oral opening creates a problem for oral hygiene, food intake and intubation. Therefore, contracture treatment is beneficial once severe limitation of function is realised.

Nuclear ploidy as an indicator of malignancy of intraductal pancreatic papillary mucinous tumors.

We carried out comparative morphometric and densitometric analysis of cell nuclei in pancreatic intraductal papillary mucinous tumors. Proliferative activity values, aneuploidy coefficient, and histogram of nuclear DNA content are recommended as additional criteria for the diagnosis of tumor malignancy.

Nuclear ploidy is an indicator of malignancy endocrine pancreatic tumor.

Comparative morphometric and densitometric studies of cell nuclei in endocrine tumors of various differentiation degree and endocrinocytes of Langerhans islet in the adjacent pancreatic tissue were carried out. Index of proliferative activity, aneuploidy coefficient, and histogram of nuclear DNA content are recommended as additional criteria for the diagnosis of endocrine tumor malignancy.

Trapezoid adipose scar local flap: postburn lateral truncal contracture elimination with trapeze-flap plasty.

Trunk burns result in various complications, deformities, and contractures. Contracture of the lateral surface of the trunk is one of the serious complications that limits movements of the spine; children experience structural changes in the form of scoliosis. Therefore, the lateral truncal contracture should be the subject of early surgical treatment.

Detection of small hypervascular hepatocellular carcinomas by EASL criteria: comparison with double-phase CT during hepatic arteriography.

Background And Aims: To compare the detectability of small hypervascular hepatocellular carcinoma (HCC) between double-phase CT during hepatic arteriography (CTHA) criteria (hypervascular on the early-phase of CTHA and corona enhancement on the late-phase of CTHA) widely introduced in Japan and EASL criteria (hypervascular on the arterial dominant phase and wash out on the equilibrium phase of dynamic CT and/or MRI).

Methods: 116 hypervascular HCC lesions (≤2 cm) of 38 patients were evaluated. CTHA was performed in every patient, both dynamic CT and dynamic MRI in 22 patients, only dynamic CT in 8, and only dynamic MRI in 8.

First web space post-burn contracture types: contracture elimination methods.

First web space adduction contractures are a common consequence of hand burns. Many reconstructive techniques are used and investigation for more effective methods continues. Effective hand reconstruction usually considers anatomy as its foundation.

Postburn perineal obliteration: elimination of perineal, inguinal, and perianal contractures with the groin flap.

Deep burns of the perineum result in perineal obliteration, hip adduction contracture, and limitation of hip range of motion. Bodily hygiene becomes difficult to maintain. Perineal obliteration is often combined with inguinal and perianal contractures and genitalia injury.

Flexion contractures of fingers: contracture elimination with trapeze-flap plasty.

Scar flexion contracture of fingers is one of the most serious consequences of hand burns and patient disability after burn. Many kinds of reconstructive techniques are currently used and new procedures are being investigated. The author presents a new method of finger contracture reconstruction developed in the process of burn reconstructive operations on hands of over a thousand patients.

Comparative characteristics of nuclear ploidy of cells in endocrine and solid pseudopapillary tumors of the pancreas.

We carried out comparative morphometry and densitometry of cell nuclei in endocrine and solid pseudopapillary tumors and of exocrinocytes and endocrinocytes of the adjacent pancreatic tissue. The nuclear size, perimeters, and DNA content were higher in tumor cells. The index of proliferative activity, coefficient of aneuploidy, and histograms of DNA content in cell nuclei are recommended as additional criteria for differential diagnosis between endocrine and solid pseudopapillary tumors.

Nuclear ploidy and intensity of proliferation of hepatocellular cancer cells.

Comparative morphometric and densitometric study of tumor cells and adjacent hepatocyte nuclei was carried out in hepatocellular cancer. Enlargement of the nuclei and increase in DNA content and index of proliferation of Ki-67 tumor cells inversely correlated with differentiation degree of hepatocellular cancer, which reflects the regularity of staged development of tumors.

Postburn hand border contractures and eliminating them with trapeze-flap plasty.

The hand burns can be complicated with the scar contracture of the ulnar or radial hand border. The contracture restricts the mobility of adjacent joints (fifth interphalangeal, wrist joints), causing deviation of the small finger and the whole hand. The contracture and deviation are caused by semilunar fold sheets of which are scars (medial contracture).

Surgical management of atherosclerotic-aetiology vasorenal hypertension.

The present retrospective study was carried out to analyse clinical outcomes of 56 surgical interventions performed on renal arteries in a total of 48 patients suffering from atherosclerotic- aetiology vasorenal hypertension (VRH). Of these, 14 patients were subjected to stenting of renal vessels, 19 underwent aortorenal prosthetic repair, 11 patients endured transaortic endarterectomy (TEA), and four cases were treated by resection of the renal artery with reimplantation. The immediate postoperative outcomes turned out positive in 81% of the patients, to have remained so within an average follow-up period of up to 5 years in 72% of the patients.

Post-burn philtrum restoration.

One of the consequences of face burn is upper lip deformation with philtrum injury. The philtrum's absence poses severe cosmetic defects. A literature review shows no effective developed technique which allows the surgeon to restore the upper lip and the philtrum in a single-stage procedure.

In memoriam of Michael Ellis DeBakey. Alternative reconstructions of carotid bifurcation for atherosclerosis: the history and the latest advances.

The paper overviews the history of reconstructive surgery for atherosclerotic lesions of carotid bifurcation, as well as indications for various revascularization procedures for internal carotid artery, based on the experience of the Vascular Surgery Department, A. V. Vishnevsky Institute of Surgery, and in particular, on 205 interventions that were carried out in 2006.

Structural-and-functional alterations in the arterial wall and clinical manifestations of nonspecific aortoarteritis.

The authors studied structural-and-functional properties of the arterial wall, also assessing elastic properties of the common femoral artery and the brachial artery flow-dependent dilatation (FDD) index in a total of thirty-six patients presenting with nonspecific aortoarteritis (NAA). The overwhelming majority of the patients, i. e.

Trapeze-flap plasty: effective method for postburn neck contracture elimination.

The new method for postburn neck contracture management is presented. The method is found to be most effective when using the local flap procedures on patients who cannot undergo complex and long surgical procedures that are aimed at both contracture elimination and neck skin restoration (children, elderly patients, patients with inadequate donor sites, and patients with cosmetically acceptable scar appearance). The method consists of the opposite transposition of trapezoid scar-fascial flaps which are prepared one on each antero-lateral neck surface.

Burned perineum reconstruction: a new approach.

The treatment of postburn contractures of perineum remains a complex and an unsolved problem. Fourteen patients were operated. According to our observations, the perineum contracture can have two formations: (a) transverse scar folds formed between both the thighs and (b) obliteration of perineum by scar tissues.

Restoration of the shape, location and skin of the severe burn-damaged breast.

Thermal injuries to the anterior chest in pre-pubescent girls result in breast contracture. During puberty, the breast parenchyma develops and grows underneath the scars, resulting in being flattened and disfigured. The breast mound, as well as the nipple-areolar complex, is partially or completely levelled out and displaced.

Surgical management of multiple posttraumatic arteriovenous fistulas of femoral vessels.

Presented herein are two case reports concerning surgical management of posttraumatic arteriovenous fistulas of femoral vessels. Case 1. A 45-year-old female patient attended with a history of a shotgun injury wound of her left femur and crus sustained when a girl of eight.
