Ultrasound images of thrombosis of caval vein inferior--three selected cases.

Thrombosis of vena cava inferior can occur as complication of numerous diseases. Because of a variety of causes, the clinical signs accompanying thrombosis are often ambiguous, which is the cause of delay in initiation of appropriate treatment. This article presents three interesting cases of thrombosis of vena cava inferior in children accompanying extensive burn, the Budd-Chiari syndrome, and prolonged presence of catheters in vessels.

[Ultrasonographic diagnosis of Meckel's diverticulum--case report].

Meckel's diverticulum is the congenital anomaly of the gastrointestinal tract affecting about 2% of the population. It is a true diverticulum containing all layers of the ileum wall. Heterotopic tissue is frequently present (25%): gastric mucosa, duodenal mucosa, jejunal mucosa and pancreatic tissue.

[Porencephaly in infants and children imaged with tomography].

On the basis of current bibliography verum and spurum porencephaly have been distinguished. Verum porencephaly originates in prenatal life and is defined as disorder of brain tissue development. Its main characteristic is that cave borders are covered with grey matter often connected with lateral ventricle.

[A case of developmental cerebral cortex disorder with epilepsy resistant to treatment].

Developmental disorders of the cerebral cortex were described as a local lesion in the right frontal lobe. Wide gyruses with increased density of cortical brain were observed. Changes in the cerebral cortex were correlated with clinical symptoms and EEG results and were responsible for the epilepsy resistant to any treatment.

[Radiologic aspects of the coexistence of vesicoureteral reflux and other abnormalities of the urinary tact in children].

In this report cases of the coincidence of vesicoureteral reflux with different congenital abnormalities have been described. Radiological and ultrasonographic examinations of 240 children with 324 vesicoureteral refluxes showed the presence in 8.7% additional congenital anomalies such as: duplex pelvicaliceal system and duplex ureter, ureterocele, horseshoe kidney, primary megaureter, ureteropelvic junction obstruction, posterior urethral valves, neurogenic bladder.

[Observation of some semen parameters in men with varicocele].

Among 172 examined male patients varicoceles have been found in 57.6% patients. The frequency of varicocele appearance increased according to the fall of sperm concentration.

[Ultrasound images of prostate and seminal vesicles in infertile male patients].

The results of clinical examinations, semen analysis and endosonographic examinations of prostate and seminal vesicles were analysed in 172 male patients treated due to infertility. Ultrasound equipment with transrectal multiplane transducers 6.5 and 7.

[Varices of the spermatic cord and endo-sonographic changes of urogenital organs in men with decreased values of certain sperm parameters].

A comparative analysis was carried out of sperm cell density, proportion of mobility and viability, and the proportion of morphologically abnormal sperm cells in 80 (74.6%) men with varices of the spermatic cord and 88 (52.4%) men without the varices.

[Some routine test parameters of semen taken from the male partner of infertile couples and the state of the urogenital tract (prostate, seminal vesicles, testicles, epididymis) examined by ultrasound].

The authors investigated 214 men with endorectal and percutaneous scrotal sonography. These men were treated for the reason of sperm defects. The age range was 22 to 52 years.
