Contrast Ultrasound

Purpose: To compare the capabilities and evaluate the effectiveness of gray-scale B-mode, Doppler mapping and contrast enhanced in the assessment of cystic renal lesions.Material and methods: Ultrasound examination (US) was performed in 61 patients with cystic kidney formations (category Bosniak ≥ II). Cysts of categories Bosniak ≥ III were histologically verified, rest (categories II–IIF) were under follow up. All patients underwent gray-scale ultrasound, color Doppler imaging and contrast enhanced (CEUS).Results: The efficiency of the B mode was: sensitivity 55.6 %; specificity 72.1 %; accuracy 62.3 %, in the CDI mode these indicators were 52.8; 80.1; 63.9 %, respectively. Contrast ultrasound significantly increased the capabilities of the method, and also made it possible to evaluate cystic formations according to the Bosniak criteria with indicators of the effectiveness of the method up to 100.0; 92.0; 96.7 %, respectively.Conclusions: CEUS demonstrated high informative value in the assessment of renal cystic formations in comparison with native ultrasound and Doppler modes, and therefore the technique should be considered as promising for inclusion in the algorithm of examination of complex renal cysts.

Objective The left atrial appendage (LAA) is the source of 90% of thrombi in patients with atrial fibrillation. Our double LAA ligation (LLAA) technique was shown to be 96% successful in a small study. However, the outcomes of these patients have yet to be compared with a set of nonligated patients. Methods From 2005 to 2012, a total of 808 patients received LAA using our double ligation technique using both a polydioxanone (PDS) II endosnare and a running 4-0 Prolene pledgeted suture. The 30-day outcomes of these patients were compared with that of nonligated patients. Fifty-six of the ligated patients had a postoperative transesophageal echocardiography (TEE). An echocardiographer reviewed the follow-up TEEs for LAA remnant and/or residual flow into the LAA using color Doppler imaging. The patients with LAA flow and/or remnant depth of 1 cm or greater were deemed to have an unsuccessful exclusion. Results The ligated group had a trend of less postoperative atrial fibrillation (19.4% vs 22.9%, P = 0.07) and an overall significantly lower in-hospital mortality (0.7% vs 3.0%, P < 0.001) and lower 30-day mortality (0.7% vs 3.4%, P < 0.0001). The LAA was successfully excluded in 53 (94.7%) of the 56 patients with TEE. Conclusions Double LAA ligation correlates with lower rates of in-hospital and 30-day mortality. This advantage comes without an increase in perioperative complications. This technique can easily be performed off or on pump, is very reproducible, and comes at a very low cost compared with LAA occlusion devices. Stroke has a multifactorial etiology; successful LLAA removes one potential source of thrombi perioperatively and in the long-term.

Pump Twin

Twin reversed arterial perfusion (TRAP) sequence, is a rare malformation occurring in monozygotic multiple gestations. One well-developed normal (pump) twin and the other twin with absent cardiac structure (acardiac), who is hemodynamically dependent on the normal (pump) twin are characteristic of this syndrome. The acardiac twin develops multiple anomalies that make survival difficult. The prognosis of the pump twin is variable with mortality rate ranging from 50% to 70%. Complications that affect the prognosis of the pump twin include complications of congestive cardiac failure due to increased cardiac demand, prematurity secondary to preterm delivery, and polyhydramnios. Because of these complications prompt detection, follow-up, and treatment of this condition is very important. We report two cases of TRAP sequence that emphasizes the importance of gray-scale and color Doppler imaging in diagnosis, detection of poor prognostic features, follow-up, and management of TRAP sequence.

Testicular torsion is one of the main causes of acute scrotum and may result in permanent damage of the testicular tissue. Color Doppler imaging has been frequently used in the diagnosis of testicular torsion and posttreatment follow-up period of the disease. There are some studies reporting the value and usefulness of diffusion-weighted imaging in the diagnosis of testicular torsion. However, to the best of our knowledge, there is no report regarding the monitoring of preoperative external detorsion in testicular torsion with diffusion-weighted imaging examination. In this article, diffusion-weighted imaging findings in the management of preoperative external detorsion in a case with testicular torsion were presented.
