Kaddaha, R. O., M. A. Haggagb, and U. Lotfyb, "Adult thoracic and abdominal aortic coarctation, combined value of MSCTA and conventional angiography in endovascular management", The Egyptian Journal of Radiology and Nuclear Medicine, vol. 47, pp. 509–520, 2016. AbstractWebsite


To detect the value of MSCTA in diagnosis and preplanning in endovascular management of adult thoracic and abdominal coarctation. The additional value of conventional angiography before or during the procedures is explained. The follow-up by either techniques is evaluated for early detection of re-coarctation and re-intervention.

Patients and methods

This retrospective study included 22 patients, 9 females and 13 males, age ranging from 17 to 49 years. The main clinical presentation was hypertension (n = 15). All patients were evaluated by MSCTA and conventional angiography with pressure gradient studies for preoperative evaluation and planning of treatment. Follow-up MSCTA was done at 6 months interval for 3 years.


MSCTA detected suprarenal MAS (n = 3), infrarenal and juxtarenal MAS (n = 10), pre- and post-coarctation dilatation of the thoracic aorta and subclavian (n = 4), thoracic collateral pathways (n = 5). Mean narrowest diameter is 2.3 mm (1.2–4.5 mm). In conventional angiography peak systolic gradient decreased from 33 to 2 mmHg. Successful endovascular repair was done in n = 15, PTA was done alone in 6 and PTA and stenting were done in n = 9. Endovascular re-intervention was done in n = 3.


Aortic COA could be found in any segment of the aorta. Proper identification of the anatomical details and pressure gradient studies are important factors affecting the plan of management.

To detect the added value of magnetic resonance arthrography (MRA) over MRI in different triangular fibrocartilage complex (TFCC) and intrinsic wrist ligament lesions.

Patients and methods

MRI and MRA were achieved in 57 patients presented with wrist pain. Another symptompless Ten control individuals with negative MRI and MRA findings were included. Images were assessed for the presence of TFCC, scapholunate ligament (SCL) and lunotriquetral ligament (LTL) lesions. Imaging findings were compared with arthroscopic findings in all cases.


Out of fifty-seven patients, 38 males (66.6%) and 19 females (33.3%) (age range 19–61 years (mean = 34.3 years) were included in the study, The sensitivity, specificity and accuracy of MRI and MRA for TFCC peripheral tears were 79.16%, 100%, 85.29% and 91.66%, 100%, and 94.11% respectively, the sensitivity, specificity and accuracy of MRI and MRA for TFCC central tears were 60%, 100%, 80% and 90%, 100%, and 95% respectively. Sensitivity, specificity and accuracy of MRI and MRA for SCL partial tears were 63.15%, 100%, 75.86% and 94.73%, 100% and 96.55%, respectively. For LTL partial tears, the values were 20%, 100%, 73.33% and 80%, 100%, and 93.33% respectively.

Abstract

PURPOSE: To determine the sonographic criteria for diagnosis of fetal intracranial hemorrhage (ICH), using both gray scale ultrasound, and tomographic ultrasound imaging (TUI).

MATERIALS AND METHODS: A prospective multicenter study, recruiting patients at risk of fetal ICH over four years. All cases with fetal ICH had serial ultrasound assessments, including TUI, fetal and postnatal MRIs.

RESULTS: Twenty-one patients were diagnosed with fetal ICH, two cases had extracerebral (subdural) hemorrhage, 16 cases had intracerebral (intraventricular) hemorrhage and three cases had combined hemorrhage. The mean gestational age at which they were diagnosed was 29.8 ± 5.2 weeks. Seventy-six percent of cases had no identifiable risk factors. IUGR was associated with 57.9% of cases. Using grey scale ultrasound, we demonstrated clear cut sonographic criteria for diagnosis of fetal ICH. TUI enabled us to detect some midline cerebral lesions not detected by grey scale 2D ultrasound alone. Fetal and postnatal MRI confirmed those findings.

CONCLUSION: Ultrasonography can be used in the detection, classification and monitoring the progression of various types of ICH. TUI is an additional diagnostic tool that might help to detect the exact size, and extent of those lesions. Fetal MRI is not superior, but might aid in the diagnosis.
