摘要:

AbstractBilateral cystic adenomatoid malformation of the lung (CAML), solid type (Stocker 111), is a rare malformation that we observed sonographically in two fetuses at 23 weeks. The ultrasonic image showed an echogenic mass compressing the heart and occupying the whole thoracic cavity. Massive ascites, probably as a result of heart failure, was apparent. The prognosis is fatal. Prenatal diagnosis enables termination of pregnancy and saves the mother from invasive procedures in case of fetal distress. In unilateral, more favorable lesions, the managing physician is prepared for respiratory distress of the newborn and an emergency operation.

摘要:

AbstractReal‐time two‐dimensional Doppler echography (2‐D Doppler), which permits both structural and blood flow evaluations simultaneously, was applied during hepatectomy in three cases. Intrahepatic portal flow was observed in one case both before and after Pringle's maneuver. Hemihepatic blood flow interruption, which was guided by 2‐D Doppler imaging, was tried in two cases. Extrahepatic blood flow was also detected easily with 2‐D Doppler techniques. This approach is useful for both anatomic and hemodynamic evaluation during hepati

摘要:

AbstractHigh‐resolution ultrasonography was performed on 14 patients with soft tissue swelling of the wrist and hand. The examination was done using a real‐time 10‐MHz sector probe placed directly on the lesion. The sonographic image could always demonstrate the liquid nature of cystic lesions. In recent ganglia, the fluid content was anechoic, and the cystic walls were rather thin; in some older lesions, irregular internal echoes and thicker walls were found. Rather often, multiple ganglia were observed, grouped in clusters. The presence of a liquid‐filled duct directed to the articular space was demonstrated in 8/11 cases (73%). This finding is considered a diagnostic characteristic of ganglia, and it is very useful for correct surgical planning. In extensor cystic tenosynovitis, the echographic picture was quite different: the anechoic cavity was longitudinal in shape, following the tendon sheath, and the communicating duct was absent. Finally, the sonographic pattern of one case of de Quervain's disease was analyzed and di

摘要:

AbstractGrowth of the fetal head has been reexamined in a longitudinal study of 32 normally growing fetuses using the head profile area (HA). The Rossavik growth model (characterized by the coefficientsc, k, ands)fit these data very well (R2[±SD] 99.6 [± 0.3]%), and regression analysis indicated that optimum results are obtained when the coefficient k is kept constant. Head area growth before 28 weeks was found to be related to the coefficient c, which was strongly correlated(R269.2%) with the time of HA growth initiation. These results suggest that c reflects the genetic factors controlling growth in the early part of pregnancy. The coefficient s was negatively correlated with c (R282.1%) and had two components, one associated withc bred. s)and one not associated with c (s‐residual). This linkage between c and s, together with the parallel head growth seen after 30 weeks, suggests the possibility of a maternal system in which genetically determined head size (c) can be sensed and modified by other factors (s) to maximize compatibility between the fetal head and maternal pel

摘要:

AbstractGrowth of the fetal abdomen has been reexamined in a longitudinal study of 32 normally growing fetuses using the abdominal profile area (AA) and the Rossavik growth model. The growth of the fetal abdomen was compared to that of the fetal head. In early pregnancy the growth rate was higher for the fetal head than for the fetal abdomen, whereas the opposite was the case in late pregnancy. The coefficientkwas lower, and the s was higher, for AA than for the head profile area (HA), giving a less prominent sigmoid shape to the AA growth curve. The best correlation to fetal weight at birth was found for the AA growth curve as a whole. The AA s‐residual correlated best of all single parameters, with the coefficient c of HA being next. The s‐residual appears to reflect the nutritional supply available in late pregnancy, and we conclude that fetal weight at birth depends more on this supply than on the genetic factors controlling fetal gro

摘要:

AbstractThe acute scrotum remains a difficult clinical challenge because of numerous etiologies including inflammatory processes, testicular torsions, traumas, and tumors that can justify early surgery. Ultrasound study appears to be the imaging modality of choice to confirm the clinical assessment. We reviewed 825 scrotal scans performed with high‐resolution scanners; 283 were considered pathologic and classified as follows: 27 tumors (9.5%), 21 traumas including torsions (7.4%), 142 infectious diseases (50.1%), 99 dystrophic diseases (29.2%), and 16 miscellaneous (5.6%). Acute scrotal pain was the only symptom in 83 cases (29.3%). In this paper, we emphasize the different roles of ultrasound depending on the initial clinical presentation, which determines the clinician's questions. In the typical cases, ultrasound has a major role in the prognosis, as it allows evaluation of the severity of the lesions. On the other hand, in atypical cases, ultrasound has a decisive role in planning the management, which will be immediate surgery when sonographic findings highly suspicious for testicular torsion or acute ischemia of the testis are found. Based on our experience, we believe that ultrasound is a highly reliable modality for guiding medical or surgical treatment of an acute scrotu
