Percutaneous ilio-caval thrombectomy with the Amplatz device: preliminary results
No full textThe Amplatz Thrombectomy Device (ATD) is a percutaneous, rotational thrombectomy catheter, capable of recirculating and homogenizing the thrombus in order to obtain mechanical clot dissolution. The authors present their experience with mechanical thrombectomy with the ATD in eight cases of ilio-caval thrombosis. Under temporary caval filter protection, the ATD was introduced through the right transjugular approach (in one patient this was used in combination with the right femoral approach) and activated for a time ranging from 90 to 180 s. Complete clearing of thrombotic material in the treated venous segments was achieved in six cases (75 %), partial success was obtained in one case (12.5 %) and failure occurred in one patient (12.5 %). One patient developed a recurrence of venous iliac thrombosis 1 week after the procedure and postphlebitic syndrome 6 months after the first episode of deep venous thrombosis, and one patient died from acute myocardial infarction, unrelated to thrombectomy session, after 3 days. A negative clinical and radiological follow-up at 3, 6, 12 and 24 months was obtained in the remaining six patients. If a fresh free-floating ilio-caval clot must be removed immediately, the ATD can be effective under temporary filter protection
Digital tomosynthesis spot view in architectural distortions: outcomes in management and radiation dose
Full text linkpurpose to evaluate if digital breast tomosynthesis spot compression view (DBT-SCV) could be an additional projection to confirm or deny architectural distortions (ADs) detected by digital breast tomosynthesis (DBT) while assessing the average glandular radiation dose. methods this is a retrospective cohort study enrolling 8864 DBT exams, of which only cases detecting primary AD and with BI-RADS 2-5 score were considered. seventy-one AD cases examined with DBT-SCV, US and MRI were evaluated for correlation in terms of BI-RADS score; variables among exams were assessed for inter-relationships. results Of all ADs identified at DBT, biopsy yielded malignancy in only 38%. PPV in identifying malignancy of ADs was higher for DBT-SCV than DBT (p < 0.05); the NPV of DBT-SCV was 94%. the difference between DBT and DBT-SCV in the detection of benign ADs was statistically significant (p < 0.05). AD without US or MRI confirmation was less likely to represent malignancy (p < 0.05). In detecting malignant cases of ADs, both DBT and DBT-SCV were strongly correlated with US and RM (Kappa > 0.90). In identifying benign cases of ADs, DBT-SCV was poorly/moderately correlated with US and RM (Kappa 0.25 and 0.66); DBT was negatively correlated with US and MRI. conclusion DBT-SCV could be useful to better characterize AD firstly identified by DBT, keeping dose levels within the reference limits. If AD is detected by DBT without an US or MRI correlate, that is not confirmed by DBT-SCV, a "wait and see " approach can be applied to reduce unnecessary biopsy

Assessment of "occasional" atherosclerotic lesions identified with computerized tomography. Analysis of tomodensitrometric findings and identification of "risk" groups in 1,500 patients
No full textAtherosclerosis is a disease with a chronic-progressive course. We report on the statistic prevalence of vascular lesions in 1,500 asymptomatic patients with vascular diseases examined with Computed Tomography (CT) for different reasons. The aortoiliac arterial district was involved in 934/1,500 patients (62.3%), with simple or calcified plaques, thrombosis or dilatations. We investigated the involvement of other arterial vessels (47%) whenever feasible (57.7% of cases). The aorta was thrombosed in 107 patients (2.8%) and the thrombus associated with a calcification and a dilated vessel in 45 of them (42.1%). The aorta or the iliac arteries were enlarged in 62 patients (4.1%) and arterial diameter exceeded 4 cm in 20 patients (1.3%). Finally, the statistical significance was analyzed considering risk factors-i.e., smoking, arterial hypertension, diabetes and hypolipoproteinemia. All the patients with 2 or more risk factors had positive CT findings; the prevalence was 75% in cigarette smokers, 83% in hypertensive, 81.3% in dislipidemic and 93.5% in diabetic patients. These data demonstrate that, in agreement with international literature reports, it is possible to single out the groups of patients that, because of their age, risk factors and sex, should be considered for color Doppler screening programs and the selected cases to be submitted to CT
