The method of treatment after Ilizarov was used in 28 patients with occlusion of lower extremity arteries, mainly of distal localization, with the III and IV degrees of ischemia. Osteotomy of mainly the tibial bone and distraction of the free osseous split was performed during 31-36 days. Two patients had fractures of the bone during operative interventions, after operation four patients had purulent complications or necrosis of the skin around the wire. The immediate positive result was noted in 20 patients. Their fate was followed-up in remote periods from 2 to 19 months, good results were observed in 18 patients. The use of the Ilizarov method was most justified in patients with the III and IV degrees of ischemia when other methods of treatment failed to give any effect and surgical reconstruction of the vessels is impossible. When treating patients with the IV degree, it is necessary to take into consideration the late appearance of revascularization and possibility of temporary deterioration. The use of the Ilizarov method foresees provision of the joint work of an angiosurgeon and a traumatologist-orthopedist. 相似文献

Neuroimaging in Pineal Tumors 总被引:4,自引:0,他引:4
F Reis MD AV Faria MD PhD VA Zanardi MD PhD JR Menezes MD F Cendes MD PhD LS Queiroz MD PhD 《Journal of neuroimaging》2006,16(1):52-58
BACKGROUND AND PURPOSE: The authors report radiological findings in 11 tumors in the pineal region, which were histologically diagnosed as germinomas, pineocytomas pineoblastomas, ependymomas, teratomas, and astrocytomas. METHODS: Computed tomography (CT) was performed in seven patients and magnetic resonance imaging (MRI) was performed in all patients. RESULTS: CT showed a solid or solid/cystic mass with variable contrast enhancement. MRI showed a heterogeneous mass, with hypointense signal on T1 and iso/hyperintense signal on T2-weighted images (WI) and gadolinium enhancement. Extension to adjacent structures occurred in five patients and spread through the cerebral spinal fluid (CSF) in two. CONCLUSIONS: Pineal region tumors have no pathognomonic imaging pattern. MRI and CT are complementary in diagnosis and are important to determine localization, extension, and meningeal spread. 相似文献

Is the outcome of in-vitro fertilization and embryo transfer treatment improved by spontaneous or surgical drainage of a hydrosalpinx? 总被引:4,自引:7,他引:4
Sowter MC; Akande VA; Williams JA; Hull MG 《Human reproduction (Oxford, England)》1997,12(10):2147-2150
A pilot study was designed to examine whether the outcome of embryo
transfer in women with a hydrosalpinx might be improved by surgical
drainage of the hydrosalpinx at the time of oocyte collection for in- vitro
fertilization treatment. A comparative, controlled but retrospective
analysis of the results was performed of all women with infective tubal
damage aged <40 years old, who had ovulatory cycles, a normal uterus and
a partner with normal spermatozoa. A standardized treatment regimen was
used. A maximum of three embryos were transferred. Hydrosalpinx was defined
by prior hysterosalpingography and/or laparoscopy with transcervical dye
injection. A total of 237 embryo transfer cycles in women with
hydrosalpinges (tubal distension not visible in 151, visible but not
drained in 30 and drained in 56) were compared with 705 embryo transfer
cycles in women with tubal disease but no hydrosalpinx. Results were
analysed in the first three cycles but also separately in the first cycle
to check for bias. Success rates were higher in the first cycle, but did
not significantly influence overall differences. Implantation rates were
significantly reduced overall in the hydrosalpinx group (8.0 versus 13.2%
for controls; P < 0.001), being 8.3% (P < 0.01) in the subgroup
without evident tubal distension and 7.5% (not significant) in the drained
hydrosalpinx group. This study shows that tubal damage with distal
occlusion is associated with a marked reduction in embryo implantation,
even in the absence of obvious fluid distension. Surgical drainage of
distended hydrosalpinges appears to offer no benefit.

Distribution of the eight components of extracellular matrix in small villi of human placenta was studied with indirect immunofluorescence. Normal full-term pregnancy was found to present rough fibers and type I collagen conglomerates accumulated in the stromal center, while type III and V collagens occurred all over the villous surface. Stromal localization of type IV collagen was recorded as well as its presence in basal membranes of the epithelium and vessels. Fibronectin showed diffuse distribution concentrating along the vessels. Laminin, entactin and in lesser degree heparan sulphate proteoglycan were registered in epithelial and vascular basal membranes. Isolated sclerosis of the villi in pathological pregnancy involved stromal accumulation of type I, III collagens, small fragments of collagens type IV, V and fibronectin. Multiple sclerosis of adherent villi demonstrated hyalin-like conglomerates of various collagens and fibronectin filling up the stroma. Laminin, heparan sulphate proteoglycan and entactin were not observed at these sites. 相似文献

The authors share their experiences with treatment of wounds of the neck in 210 patients. Major vessels were injured in 85 of them (40.5%), arterial vessels being injured in 19 patients, venous vessels in 23 patients. 43 patients had wounds of the hollow, parenchymatous organs and nerves. All the patients with wounds of the hollow and parenchymatous organs recovered. Lethality among the patients with wounds of the major vessels was 11.9% and was due to a combination of injuries of the vessels and blood loss incompatible with life. Active surgical treatment of penetrating wounds of the neck with careful revision of the wound, use of emergency esophagogastroduodenoscopy, laryngotracheobronchoscopy, X-ray examination allow the amount of diagnostic errors and lethality to be reduced. 相似文献

Development of left ventricular pseudoaneurysm is a rare complication of mitral valve surgery and requires urgent surgical intervention. We describe a case of pseudoaneurysm of membranous septum following repeat mitral valve replacement with the use of multimodality imaging. 相似文献
