Portal vein aneurysm: report of six cases and review of the literature

Portal vein aneurysm is very rare, and its relation to portal hypertension has been emphasized. We report six cases of portal vein aneurysm (five extrahepatic and one intrahepatic). All patients were asymptomatic and had no signs suggestive of portal hypertension; the lesion was incidentally detected by ultrasound. Color Doppler sonography showed a constant hepatopetal flow along the aneurysmal wall, which immediately led to the diagnosis. We stress the usefulness of color Doppler sonography for studying the hemodynamics of this vascular anomaly and briefly review the literature.

Factors related to detection of blood flow by color Doppler ultrasonography in intussusception

Color Doppler ultrasonography was performed in 125 patients with 134 intussusceptions. Color flow was present in 121 cases of intussusception (group A) and was absent in 13 cases (group B). Young age and duration of symptoms greater than 48 hr were significantly related to the nonvisualization of blood flow detected by color Doppler sonography (P < 0.05). The successful rate of air reduction was significantly higher in group A than in group B (109 of 121 versus 4 of 13). Color Doppler ultrasonography is useful to predict the reducibility of an intussuscepted intestine. The nonvisualization of blood flow by this method is not a contraindication for air reduction.     

Color Doppler sonography of bile duct tumor thrombi in hepatocellular carcinoma.

OBJECTIVE: To determine with the use of color Doppler sonography whether bile duct tumor thrombi had detectable vasculature in hepatocellular carcinoma. METHODS: Among 491 patients with tissue-proven hepatocellular carcinoma, 9 (1.8%) had bile duct tumor thrombi. All 9 patients had spectral Doppler sonography guided by color Doppler sonography (3.75-MHz convex probe). RESULTS: All 9 patients had dilated bile ducts with isoechoic thrombi. Eight patients had tumors infiltrating into and obstructing adjacent major bile ducts. The other patient had common hepatic duct tumor emboli that were not adjacent to primary tumors. Color signals were detectable within bile duct tumor thrombi in 7 patients. All of them had pulsatile waveforms on spectral analyses. CONCLUSIONS: Bile duct tumor thrombosis with obstructive jaundice was a rare complication of hepatocellular carcinoma. A detectable color signal with pulsatile waveforms was shown in most cases by color Doppler sonography with spectral analyses.     

Splenic artery aneurysm: value of color Doppler and the limitation of gray-scale ultrasonography

Background: To reevaluate the advantages and limitations of gray-scale and color Doppler sonography in the diagnosis of splenic artery (Sp-A) aneurysm. Methods: We reviewed the gray-scale and color Doppler sonograms of five cases with Sp-A aneurysm (four patients with portal hypertension and one patient without portal hypertension). Color Doppler sonography was performed in all five patients, and power Doppler sonography was performed in three. Results: Gray-scale sonography failed to detect the aneurysm in four of five cases because of a surrounding splenorenal (Sp-R) shunt in three patients and marked calcification of the aneurysmal wall in one patient. Pulsed Doppler sonography showed a slightly turbulent pulsatile flow along the aneurysmal wall, which immediately led to the diagnosis in four cases, including the three cases with Sp-R shunt. In one case, color Doppler sonography failed to detect the aneurysm because of a markedly calcified aneurysmal wall, although power Doppler sonography could visualize the aneurysm. Conclusions: Gray-scale sonography is not a useful diagnostic tool for Sp-A aneurysm. Clinicians should use color Doppler sonography in the evaluation of the splenic hilus in patients with Sp-R shunt to find a small Sp-A aneurysm. The addition of power Doppler sonography is helpful in visualizing calcified Sp-A aneurysms.     

视网膜母细胞瘤超声图像及血流特征

Arteriovenous fistula after renal biopsy in children.

Our objective was to assess the prevalence and history of arteriovenous fistula after renal biopsy in pediatric patients by the use of color Doppler sonography. Fifty patients, aged 6 days to 18.5 years, underwent sonographically guided renal biopsy. Color Doppler sonography was performed prior to, during, and after the procedure. Postbiopsy hematoma was detected in 46 patients (92%), of whom 10 suffered clinically significant bleeds. Six patients (age range, 8 to 18.5 years) developed postbiopsy arteriovenous fistula. In three cases the arteriovenous fistula diminished spontaneously, one persisted without symptoms, and two symptomatic arteriovenous fistulas needed coil implantation. Color Doppler sonography demonstrated all arteriovenous fistulas 4 hours after the procedure and duplex Doppler sonography demonstrated the flow disturbances in the feeding and draining vessels. We conclude that color Doppler sonography allows noninvasive detection and follow-up study of postbiopsy arteriovenous fistula, thus helping to define management after interventional procedures.     

The diagnostic value of levovist in Doppler imaging of visceral arteries in patients with abdominal angina before and after angioplasty

PURPOSE: To assess the diagnostic value of Levovist in the ultrasound imaging of visceral arteries in patients with clinical symptoms of abdominal angina, before and after percutaneous transluminal angioplasty (PTA). MATERIAL AND METHOD: During a 12-month period (2000/2001) five patients with visceral arterial stenoses had ultrasound examinations and a subsequent PTA procedure. Indications for ultrasound examination were abdominal angina symptoms persisting for 3-5 years, (postprandial abdominal pain, diarrhea, and vomiting). In all patients ultrasound examinations were performed using color and spectral Doppler before and after Levovist injections. Color Doppler images and maximum blood flow velocity in stenosed visceral arteries were assessed. Patients underwent control Doppler examinations with Levovist injections to assess the effect of PTA. RESULTS: In three patients conventional Doppler examination did not allow proper evaluation of visceral arteries, because of weak color and spectral Doppler signal and in two remaining patients visceral arteries were not visualized at all. In all five patients strong enhancement of color and spectral Doppler signal was observed after Levovist administration. In all these cases a hemodynamically significant stenosis was diagnosed: coeliac trunk-2 and superior mesenteric artery-3. PTA was performed successfully in these patients. In one of them ultrasound examination done before Levovist injection allowed good visualization of treated SMA and showed good PTA result. In the remaining four patients Doppler examination with the use of Levovist demonstrated visceral arteries well and confirmed successful PTA procedures. CONCLUSIONS: The use of Levovist makes the diagnostic efficiency of Doppler examinations much higher. In most cases it allows an unequivocal diagnosis of visceral artery stenosis in patients with abdominal angina symptoms. The Doppler examination with the use of Levovist is the method of choice in follow-up after PTA.

Color Doppler sonography: Anatomic and physiologic assessment of the thyroid

The purpose of this study was to assess the potential application of color Doppler sonography in thyroid imaging. Thyroid nodules and other thyroid pathology detected by color Doppler ultrasound and nuclear scintigraphy were compared in 115 patients. The majority of “cold” nodules demonstrated a peripheral rim of color flow and no internal color flow with color Doppler sonography. A large number of “hot” nodules demonstrated internal color flow. Color Doppler sonography was helpful in delineating nodules in otherwise inhomogeneous glands. We determined that color Doppler cannot reliably distinguish benign from malignant thyroid nodules; fine-needle aspiration biopsy remains the most accurate method in differentiating benign and malignant lesions. We suggest that color Doppler sonography plays only a limited role in the evaluation of nodular thyroid disease at this time. The color Doppler appearance of other thyroid disorders (including toxic multinodular goiter, Graves' disease, and thyroiditis) is discussed. © 1995 John Wiley & Sons, Inc.
