{"title":"Pressed for time: The sonographic signs of testicular compartment syndrome","authors":"Khara Johnson‐Smith","doi":"10.1002/sono.12287","DOIUrl":"https://doi.org/10.1002/sono.12287","url":null,"abstract":"Testicular compartment syndrome (TCS) is the compromise of microcirculation as a result of extraluminal compression or increased venous resistance, which leads to hypoxia and eventual infarction. Injury occurs as a result of increased pressure within a small or low-compliance compartment resulting in a reduction or complete loss of perfusion to the tissues and subsequent ischemia. Compartment syndrome is most commonly reported in the upper and lower limbs; however the testicles are susceptible and sensitive to expansive processes due to the low compliance of the surrounding tunica albuginea. This case report aims to add to the small number of case reports currently available on this topic. There are multiple known causes of compartment syndromes such as crush injury, arterial occlusion, fractures associated with trauma and prolonged malposition of the limb. Due to the fragility of the capillaries and testicular microvasculature any expansive conditions of the testicle or scrotum such a hydrocele, abscess, epididymitis or epididymo-orchitis can cause TCS. As TCS results in hypoxia, it is considered a urological emergency and the success of intervention is time dependant. Ultrasound is well-recognised as the modality of choice for testicular imaging as it does not use ionising radiation, is non-invasive and readily available. Technological advancements have resulted in high resolution imaging which is highly sensitive to scrotal pathology when used in conjunction with colour and spectral Doppler. Ultrasound can provide detailed information about testicular perfusion and detect hypervascularity; the cardinal sign of inflammation. With spectral Doppler, sonographic assessment of the testes can differentiate between inflammatory causes of pain and torsion or other surgically treatable urgent conditions. Therefore, the success of surgical intervention for patients with TCS may be highly dependent upon its diagnosis and the recognition of sonographic signs. This case report aims to raise awareness about TCS for both treating physicians and sonographers and demonstrates two possible outcomes that may result from different management strategies. This case report also highlights the relevance of reversed end diastolic flow (REDF) and the importance of spectral Doppler in sonographic assessment of the testes.","PeriodicalId":29898,"journal":{"name":"Sonography","volume":"71 1","pages":"40 - 44"},"PeriodicalIF":0.4,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83158147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zelesco","doi":"10.1002/sono.12285","DOIUrl":"https://doi.org/10.1002/sono.12285","url":null,"abstract":"Fetal lower urinary tract obstruction (LUTO) affects 2.2 per 10,000 births. It can be a consequence of a range of pathological processes. It has a high mortality and morbidity. Ultrasound plays a pivotal role in the diagnosis of fetal obstructive uropathies, both pre and postnatally. In a study published in 2014, Dias et al. stated that prenatal ultrasound has a 95% sensitivity and 80% specificity in diagnosing LUTO. Posterior urethral valves (PUVs), ureterocele, bladder stone, bladder diverticulum, and meatal stenosis are common causes of urinary obstruction. Anterior urethral valves (AUVs) are a rare cause of congenital obstruction of the male urethra compared to the more commonly encountered PUV. AUV has a profound effect on the bladder, urethra, and upper urinary tract. It shares common prenatal sonographic features with other causes of LUTO. Sonographic features depend on the time of presentation and the severity of the obstruction. Antenatally, on ultrasound megacystis, hydronephrosis, and oligohydramnios may be seen. Postnatally, LUTO may result in severe renal dysfunction. In these cases, renal transplantation may be the only option to facilitate normal renal function. Rarely, extravasation of urine from the upper urinary tract, or rupture of the bladder may occur to relieve urinary pressure and prevent further renal damage. Spontaneous rupture of the fetal bladder in utero is a rare complication of LUTO. We present a case of late presentation of spontaneous bladder rupture in a 34-week 1-day-old male fetus with a postnatal diagnosis of AUV.","PeriodicalId":29898,"journal":{"name":"Sonography","volume":"118 1","pages":"180 - 184"},"PeriodicalIF":0.4,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85372745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is the mechanical restriction of the heart muscle by the epicardial leads. Epicardial pacing leads are leads surgically inserted to pace the heart extrinsically, when the hearts own intrinsic pacing system is faulty. Movement or slippage of lead position can effectively result in physical restriction of heart muscle growth. This strangulation of the heart has been documented to cause ischaemia and systolic dysfunction (as a result of compressed coronary arteries), mitral valve dysfunction (obstruction or regurgitation) or right ventricular outflow tract obstruction. This case discusses a 16-year-old male who underwent epicardial lead pacing as an infant for congenital heart block and presented at review with new symptoms of lethargy and “falling behind his peers.” The transthoracic echocardiogram (TTE) showed moderately reduced left ventricular (LV) function with a bright, compressed mitral valve annulus, as well as subtle right ventricle (RV) cavity indentation suggesting possible strangulation from redundant epicardial leads.","PeriodicalId":29898,"journal":{"name":"Sonography","volume":"67 6 1","pages":"172 - 175"},"PeriodicalIF":0.4,"publicationDate":"2021-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76495735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
