RESUMEN
Objective:To explore the high-frequency ultrasonographic and clinical features of superficial intravascular tumors.Methods:Thirteen superficial intravascular tumor patients who underwent ultrasound examination form Beijing Jishuitan Hospital during 2016-2020 were retrospectively analyzed. The location, anatomic blood vessels, shape, size, boundary, internal echo, blood flow and clinical characteristics of the tumors were analyzed.Results:Among the 13 cases, most of the tumors were oval like or long strip, and a few were round like. All 11 cases of primary intravascular tumors showed hypoechoic mass; 2 cases of intravascular metastasis or recurrence showed solid hypoechoic with hyperechoic mass. Arterial blood flow spectrum was detected in 12 cases. Two patients with glomus tumor showed typical tenderness at the fixed point. Two patients had a history of bone tumors in the upper or lower extremities.Conclusions:High frequency ultrasound can clearly recognize the location of the superficial intravascular tumors, describe the morphological characteristics and sonographic features of the tumor, then help to make a more accurate qualitative diagnosis.
RESUMEN
Objective:To measure the pubo-femoral distance of hips of the infants diagnosed with Graf type Ⅰ by high frequency ultrasound.Methods:A total of 1 084 infants(2 168 hips) diagnosed with Graf type Ⅰ by ultrasonography were collected in Beijing Jishuitan Hospital from June 2019 to May 2020. The ultrasonographic examinations included Graf method and pubo-femoral distance measurement. The 95% medical reference value was adopted to confirm range of normal values of the pubo-femoral distance. And the differences of the pubo-femoral distance between different gender, age and bilateral hip were compared.Results:The pubo-femoral distance of hips diagnosed with Graf type Ⅰ was (0.27±0.06)cm, the pubo-femoral distance of males was(0.27±0.06)cm, the pubo-femoral distance of females was (0.27±0.07)cm. The 95% medical reference value was 0.15-0.38 cm. The 95% medical reference value of males was 0.15-0.39 cm, and the 95% medical reference value of females was 0.13-0.41 cm. There were no significant differences between the sexes or between the age(all P>0.05). The difference between the bilateral hip joints from the same infant was statistically significant[(0.274±0.064)cm vs (0.265±0.064)cm, P<0.05]. Conclusions:The 95% medical reference value of hip diagnosed with Graf type Ⅰ is 0.15-0.38 cm.
RESUMEN
Objective@#To discuss the value of femoral head coverage (FHC) in the follow-up of infants with developmental dysplasia of the hip(DDH).@*Methods@#Two hundred and seventeen DDH infants(434 hips) diagnosed by clinical examination and ultrasonography were chosed as treatment group, and then received the brace treatment and followed up with ultrasonography. Four hundred and sixteen infants(832 hips) with normal hips diagnosed by clinical examination and ultrasonography were chosed as control group. The ultrasonographic examination included Graf method and FHC measurement. The infants in the treatment group were followed up with ultrasonography examination up to the age of 6 months.@*Results@#The FHC in the control group was (59.69±4.36)%. In the treatment group, 302 hips were diagnosed to be DDH.Among them, 36 hips were Graf type Ⅱa, 132 hips were Graf type Ⅱb, 69 hips were Graf type Ⅱc, 8 hips were Graf type D, 41 hips were Graf type Ⅲ, and 16 hips were Graf type Ⅳ. The FHC of these hips were (51.33±5.18)%, (53.07±3.94)%, (44.52±5.32)%, (38.70±5.85)%, (27.23±6.82)% and 0, respectively. After treatment, 222 hips became Graf type Ⅰ, 49 hips were improved, and their FHC increased. Twenty-eight hips were not significantly improved after treatment, but the FHC of most hips (including 14 hips of type Ⅱb, 3 hips of Ⅱc and 4 hips of type Ⅲ) increased. Three hips of Graf type Ⅲ aggravated to Graf type Ⅳ, and the FHC decreased to 0.@*Conclusions@#The FHC has important value in the follow-up of infants with DDH.
