Echo Doppler color flow (EDCF) evaluation of vascular pathology in pediatric age groups
Insights
Ultrasonography, including Doppler and Echo Doppler Color Flow (EDCF), offers a valuable, non-invasive diagnostic tool for pediatric vascular diseases like arteriovenous fistulas and pseudoaneurysms, aiding in preoperative assessment and surgical follow-up.
Area of Science:
- Pediatric vascular diseases
- Diagnostic imaging in children
- Non-invasive angiology
Background:
- Vascular diseases in children are rare but complex.
- Traditional diagnostic methods were invasive (e.g., arteriography).
- Emerging ultrasonographic techniques offer new pediatric applications.
Purpose of the Study:
- To evaluate the utility of Doppler and Echo Doppler Color Flow (EDCF) in diagnosing pediatric vascular diseases.
- To compare diagnostic criteria in children versus adults.
- To assess the role of EDCF in preoperative diagnosis and postoperative follow-up.
Main Methods:
- Doppler c.w. and EDCF were used to examine 15 children with vascular diseases (AVF, pseudoaneurysms, angiomas/cysts).
- Three additional cases with suspected vascular disease were evaluated.
- Arteriography was used for confirmation in two congenital AVF cases.
Main Results:
- Doppler and EDCF proved useful for preoperative diagnosis.
- Diagnostic criteria in children differed from adults, with indirect signs often noted for AVFs.
- Pseudoaneurysms were readily detected by EDCF.
- Ultrasonography accurately identified vascular defects later confirmed and corrected surgically in 9 children.
- EDCF was effective for postoperative follow-up in 7 cases.
Conclusions:
- Ultrasonographic methods, including Doppler and EDCF, are valuable for diagnosing pediatric vascular diseases.
- These techniques are suitable for screening young patients and for surgical follow-up.
- The study supports broader use of ultrasonography in pediatric angiology.
Abstract:
Although rarely observed, vascular diseases in children constitute a complex clinical problem. Until recently the diagnostic approach to infant vascular diseases was based on invasive methods such as arteriography, but now the use of ultrasonographic methods such as Doppler c.w. and Echo Doppler Color Flow (EDCF) in angiology can offer new and interesting application even in the pediatric age range. In the present study 15 children affected by vascular diseases (eight with arteriovenous fistulas (AVF), two with pseudoaneurysms, and five with angiomas or cysts) either of iatrogenic or congenital etiology, were examined by Doppler c.w. and EDCF. In three additional cases a suspected vascular disease was not confirmed. The data obtained by Doppler c.w. and EDCF proved useful to perform a preoperative diagnosis; however some diagnostic criteria differed from those described in adulthood, as in the AVF cases, for instance, we observed the prevalence of indirect signs such as alterations of venous flow, and the presence of "multicolored speckled mass" and of "the spreading of the color in extravasal space" rather than a direct connection between an artery and a vein. Also pseudoaneurysms were easily detected by EDCF. In two cases of congenital AVF, the diagnosis was confirmed by arteriography. Surgery was performed in 9 children, 7 with AVF and 2 with pseudoaneurysm; in all cases, the vascular defect detected by ultrasonography was visualized and corrected. In 7 cases EDCF was also used in the follow-up. In conclusion this study suggests a possible more extensive use of ultrasonographic methods in the diagnostic approach to vascular diseases in pediatric age groups, and points out their validity in screening very young patients and in their surgical follow-up.
