153. High resolution non invasive assessment of vessel volume and any obstructing volume in animals and in volunteers by sequential transcutaneous colour doppler ultrasonography in vivo

Calibre-persistent labial artery (CPLA) is a commonly underdiagnosed vascular lesion of the lip. CPLA is an arterial branch that penetrates the submucosal tissue without loss of calibre. Clinical diagnosis is significant as misdiagnosis can lead to profuse haemorrhage following an excisional biopsy or surgical excision. Colour Doppler ultrasonography is a safe and non-invasive diagnostic tool to confirm the diagnosis. Here, we report a case of a 24-year-old man who complained of an asymptomatic pulsating non-progressive nodule on the left side of upper lip initially diagnosed as peripheral angiomatous lesion. Diagnosis was confirmed by high-resolution Colour Doppler Ultrasonography. The purpose of this case report is to highlight the clinical importance and diagnosis of a rarely reported soft tissue swelling of the lip to the attention of clinicians.

Santa Inês

Context In vivo embryo production, also called multiple ovulation and embryo transfer, can accelerate genetic gain, and thus improve animal production. However, there are issues limiting a wider use of this biotechnology in sheep livestock. Aims This study aimed to determine (1) whether a previous response to superovulation (SOV) can be used as a criterion to select ewes for in vivo embryo production, (2) whether the intensity of the SOV response (number of corpora lutea, CL) can affect the embryo recovery rate, and (3) whether the number of CL quantified by colour Doppler ultrasonography can be used to calculate the recovery rate. Methods Twenty-five Santa Inês ewes underwent SOV three times (SOV1, SOV2 and SOV3), with 200 mg FSH and natural mating. The number of CL after each SOV was determined by laparoscopy and by colour Doppler ultrasonography. Key results The number of CL significantly decreased (P < 0.05) after SOV1 (7.5 ± 4.8) to 3.0 ± 5.0 at SOV 2 and 2.2 ± 3.5 at SOV3. Strong correlations were observed between SOV2 and SOV3 in terms of numbers of CL (r = 0.86, r2 = 0.74; P < 0.0001) and viable embryos (r = 0.79, r2 = 0.63; P < 00001). However, no correlations were observed between SOV1 and SOV2 or between SOV1 and SOV3. Recovery rate did not differ with the intensity of the SOV response (≤6, 7–10, >10 CL) or between the methods used to quantify CL. Conclusions Ewes did not show the same pattern of response when submitted to successive FSH-based SOV. The intensity of the SOV response did not affect the recovery rate, and the number of CL estimated by colour Doppler ultrasonography can be used to calculate the recovery rate. Implications Selecting sheep embryo donors by a previous SOV response is not always feasible. The recovery rate is homogeneous and it is not affected by the intensity of the SOV response. A nonsurgical technique can be used to assess the recovery rate, improving animal welfare in MOET programs.

Chiari Syndrome

Budd-Chiari Syndrome (BCS) is known as a disease caused by the presence of outflow obstruction of the hepatic vein and is commonly not considered as a diagnosis. Such obstruction may happen in all hepatic vein flow points, starting from small veins to the inferior vena cava opening in the right atrium, regardless of the aetiology. This syndrome occurs in approximately 0.001% population and has various aetiologies, including congenital and acquired prothrombotic conditions, myeloproliferative disease, and oral contraceptives use. Advancement in imaging enables most BCS to be diagnosed based on non-invasive imaging tests. Colour Doppler ultrasonography, which has sensitivity and specificity rate of 85-95%, is an appropriate technique for early investigation of Budd-Chiari syndrome. Colour Doppler ultrasonography and MSCT with contrast have a significancy rate of 85-91.3% with a p value 0.05 between both modalities in diagnosing BCS. Management of BCS starts with the non-invasive to highly invasive procedures, consisting of medical or recanalization therapy to prevent necrosis.
