Abstract
Renal transplant is the first-line treatment of end-stage renal disease. The increasing number of transplants performed every year has led to a larger population of transplant patients. Complications may arise during the perioperative and postoperative periods, and imaging plays a key role in this scenario. Contrast-enhanced US (CEUS) is a safe tool that adds additional value to US. Contrast agents are usually administered intravenously, but urinary tract anatomy and complications such as stenosis or leak can be studied using intracavitary administration of contrast agents. Assessment of the graft and iliac vessels with CEUS is particularly helpful in identifying vascular and parenchymal complications, such as arterial or venous thrombosis and stenosis, acute tubular injury, or cortical necrosis, which can lead to graft loss. Furthermore, infectious and malignant graft involvement can be accurately studied with CEUS, which can help in detection of renal abscesses and in the differentiation between benign and malignant disease. CEUS is also useful in interventional procedures, helping to guide percutaneous aspiration of collections with better delimitation of the graft boundaries and to guide renal graft biopsies by avoiding avascular areas. Potential postprocedural vascular complications, such as pseudoaneurysm, arteriovenous fistula, or active bleeding, are identified with CEUS. In addition, newer quantification tools such as CEUS perfusion are promising, but further studies are needed to approve its use for clinical purposes. ©RSNA, 2024 Supplemental material is available for this article.

Abstract
This case series aims to explore the application of preoperative CT guided Botox injections in three different cases of abdominal wall reconstructions. Each of the three cases highlights the role of chemical component separation in achieving myofascial release and contributing to a successful surgical repair. The use of Botox in the preoperative planning of abdominal wall repair aims at creating a tension-free environment for midline closure and promoting an overall positive postoperative course for the patient. This case series presents as a valuable contribution to the different surgical approaches in abdominal wall reconstruction and the collaboration between Interventional Radiology and Surgery in treating such patients.

Abstract
Pseudoaneurysms are a commonly encountered pathology, though pseudoaneurysms of the visceral arteries are a less frequent, but potentially deadly entity. Transarterial embolization is the typical treatment of visceral pseudoaneurysms, but success is dependent on anatomy that is conducive to selecting the supplying vessel. Abdominal ultrasound is a viable method to effectively treat visceral pseudoaneurysms when transarterial embolization is not possible. It is also an excellent example of the growing utilization of ultrasound guidance in various interventional radiologic procedures. The usefulness of ultrasound is demonstrated in this case report, where a left gastric artery pseudoaneurysm was embolized through ultrasound guidance.

Abstract
Splenic artery aneurysm (SAAs) rupture is associated with a high mortality rate. Regular surveillance with imaging before and after intervention is crucial to guide best evidence treatment. The following study aimed to determine the efficacy of color Doppler ultrasound imaging (DUS) compared to digital subtraction angiography (DSA) and magnetic resonance angiography (MRA) as a follow-up modality after selective coil embolization of true SAAs. We analyzed data from 20 patients, 15 females (48.1 ± 16.1 years) undergoing selective SAA coil embolization using detachable fibered embolization coils. Imaging using DUS, MRA, and DSA was performed 3 months after the initial embolization or the consequent re-embolization procedure. Primary clinical success, defined as Class I aneurysm occlusion, on 3-month follow-up was seen in 16 (80.0%) patients. DUS had a sensitivity of 94.4% and a specificity of 42.9% when compared to DSA and 92.3% and 30%, respectively, when compared to MRA in identifying Class I aneurysm occlusion. The positive predictive value (PPV) of DUS in identifying the need for re-embolization was 75.0%, while the NPV of DUS in these terms was 90.5%. DUS showed a high sensitivity in detecting aneurysm occlusion and clinical success, simultaneously exhibiting poor specificity. Still, with caution, this follow-up modality could be used for monitoring select low-risk patients after selective embolization of SAAs. DUS could provide a higher cost-to-benefit ratio, enabling more systematic post-procedural follow-up, as it is far more commonly used compared to MRA and non-invasive compared to DSA.

Abstract
Splenic artery pseudoaneurysm (PSA) is a contained vascular wall lesion associated with a high mortality rate, generally related to pancreatitis, trauma, malignancy, iatrogenic injury, and segmental arterial mediolysis. Computed tomography angiography allows us to visualize the vascular anatomy, differentiate a PSA from an aneurysm, and provide adequate information for endovascular/surgical treatment. The present review reports on the main state-of-the-art splenic artery PSA diagnosis, differentiating between the pros and cons of the imaging methods and about the endovascular treatment.

Successful endovascular embolization of a giant splenic artery pseudoaneurysm secondary to a huge pancreatic pseudocyst with concomitant spleen invasion. Pol J Radiol 2021; 86:e489-e495.

Abstract
Pseudoaneurysms of the pancreatic and peripancreatic arteries is a well-known complication of chronic or necrotizing pancreatitis due to proteolytic enzymatic digestion of the arterial wall. A major part of peripancreatic pseudoaneurysms involve the splenic artery, but any peripancreatic artery may be involved and bleed. They are potentially life threatening for patients, due to spontaneous intraperitoneal rupture, rupture and fistulization into the surrounding organs, or fistulization into the pancreatic duct. Small ones are usually asymptomatic and are often diagnosed incidentally, while giant (> 5 cm) aneurysms and pseudoaneurysms are symptomatic and may be detected as a pulsatile mass in the upper-left quadrant or epigastrium. Imaging plays a key role in the identification of splenic artery aneurysms and pseudoaneurysms, while angiography still represents the gold standard for the diagnosis, although nowadays it plays a prominent role in treatment. Treatment of splenic artery pseudoaneurysms is mandatory because of the high probability of rupture, with a mortality rate of up to 90%. The gold standard treatment is represented by surgery, with a mortality rate between 16% and 50%. In recent years the endovascular approach has proven to be an effective alternative treatment for splenic artery pseudoaneurysms, and it is currently the method of choice. In this article, we present the case of a ant pseudoaneurysm of the splenic artery due to huge pseudocysts in a young alcoholic patient with recurrent and chronic pancreatitis, complicated by fistulization and invasion of spleen parenchyma and arteriovenous fistula.

Abstract
Conventional ultrasound imaging (US) is the first-line investigation in acute
non-traumatic abdominal emergencies, but sometimes it needs further
examinations, such as computed tomography (CT), to reach a certain
diagnosis. Contrast-enhanced ultrasound (CEUS), through injection of
contrast medium, may provide the radiologist with additional information
that could not be investigated with baseline US. It could help reach a
diagnosis and rapidly determine the proper therapy in an emergency setting.
The purpose of this review is to explain and illustrate the various
possibilities and limitations of CEUS in acute non-traumatic abdominal
diseases, in particular acute inflammation, parenchymal infarcts, and
hemorrhages.

Abstract
BACKGROUND Primary retroperitoneal liposarcoma (PRPLS) is a rare soft tissue tumor with nonspecific clinical symptoms; it has different computed tomography (CT) image features according to pathological types. Some patients with a single tumor have been previously reported in the literature. We present an exceptional case of a PRPLS patient with multiple large tumors exhibiting different patterns of appearance on CT and confirmed as atypical lipomatous tumor/well-differentiated liposarcoma by postoperative pathology.
CASE SUMMARY A 64-year-old man presented with abdominal distension for 1 year. The patient was diagnosed with PRPLS based on physical examination, laparotomy, ultrasonography, CT scan, and surgery. Both of the tumors were completely resected through surgery and confirmed as atypical lipomatous tumor/well-differentiated liposarcoma by postoperative pathology. The postoperative course was uneventful without recurrence or metastasis, as demonstrated by abdominal-pelvic CT during an 18 mo follow-up.
CONCLUSION Multiple large Well-differentiated liposarcomas with different patterns of appearance on CT image can occur simultaneously in the same patient, to which more attention should be paid to make an effective differential diagnosis.

Abstract
Pseudoaneurysm (PSA) formation is the most common arterial complication of endovascular procedures requiring arterial puncture. The present study reported a case of a 72-year-old male patient with iatrogenic femoral artery PSA treated with contrast-enhanced ultrasound (CEUS)-guided thrombin injection. Conventional ultrasound (US) and CEUS were used to diagnose, guide treatment, and evaluate the treatment efficacy. In the case, the PSA was successfully occluded with 1000 IU of thrombin. During the follow-up after 48 hours of thrombin injection, US found that the PSA had complete thrombosis without arterial supply. No complications occurrence in the course of the treatment. CEUS-guided thrombin injection for the treatment of PSA was effective and safety and the associated literatures were also reviewed.

Abstract
BACKGROUND Active bleeding due to arterial injury following the acupuncture can sometimes represent a life-threatening complication. Only few reports of an actively bleeding hematoma diagnosed by contrast-enhanced ultrasound, which enables the depiction of vascular, have been reported.
CASE SUMMARY Here, we report the case of a 75-year-old woman, who presented with sudden swelling, ecchymosis, and pain in the upper left limb. She underwent an acupuncture treatment of traditional Chinese medicine followed by a deep shoulder massage 2 d before admission to hospital. A few hours after the massage, her left upper arm was red, swollen and progressively aggravated. Ultrasonography showed a large hematoma (11.2 cm × 3.5 cm × 3.4 cm) beside the left brachial artery. Color Doppler ultrasound revealed that blood flow signals of the arteries branched into the hematoma. The contrast-enhanced ultrasound showed microbubbles from the brachial artery passing into the hematoma, diffused within the hematoma with the local surge of red blood cells, and disappearing after approximately 17 s. The microbubbles were likely due to bleeding from the arteries. After pressure bandaging treatment, the hematoma became smaller (3.1 cm × 1.7 cm) and organized according to ultrasonography performed 20 d later.
CONCLUSION This case highlights the ultimate importance of contrast-enhanced ultrasound for the diagnosis of an actively bleeding hematoma.

Abstract
The pseudoaneurysm (PA) is a perfused sac directly connecting with the arterial lumen by an interruption of the vessel wall continuity, more commonly secondary to trauma or iatrogenic causes. Aim of our study was to determine the accuracy and usefulness of Doppler techniques in the diagnosis of peripheral iatrogenic PAs secondary to minimally invasive procedures. From a three year prospective research, 20 Duplex Ultrasound (DUS) studies in as many patients presenting with periarterial pulsating mass clinically suspected for PA secondary to minimally invasive procedures were selected. The PA final diagnosis was confirmed by angiography in 12 patients (60% cases), by computed tomography angiography in 5 patients (25%), by surgery in 2 patients (10%), and by magnetic resonance angiography in 1 patient (5%). The vessels involved by PA formation were: common femoral artery in 8 cases (40%); superficial femoral artery in 4 cases (20%); brachial artery in 3 cases (15%); popliteal artery in 2 cases (10%); superficial temporal artery (STA) in 2 cases (10%); dorsal medial digital artery of the foot in 1 case (5%). Our study confirmed the usefulness of doppler techniques in the diagnosis of peripheral iatrogenic PAs. Specifically, a sensitivity of 90-95%, a specificity of 100% and predictive values of 100% (VPP) and 83-90% (VPN) were reported. The radiologist must always suspect a PA in the differential diagnosis of lesions contiguous to an artery vessel. This is to prevent potential complications such as e.g. massive haemorrhage. In this order, DUS allows a careful selection of patients who require to undergo in-depth imaging methods or surgical therapy, thus contributing to a significant reduction of contrast medium and exposure to ionizing radiation.

Gastroesophageal and gastric ultrasound in children: the state of the art. J Ultrasound 2020; 24:11-14. [PMID: 32361921 DOI: 10.1007/s40477-020-00471-w] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Accepted: 04/23/2020] [Indexed: 12/16/2022] Open
Abstract
In previous years, the role of gastroesophageal (GE) ultrasound as a diagnostic tool in gastroesophageal reflux disease (GERD) has been disputed. Most authors believe that it is difficult to diagnose GERD without correlation studies between esophageal pathology and ultrasonographic signs. Indeed, there are many anatomic descriptions of the normal GE junction. The fact that GERD diagnosis was made by morphological studies was believed to be an incorrect deduction. We revisit the pathophysiologic data concerning the gastroesophageal junction and gastric function and review the data in the literature of the past 30 years.

Intraoperative microvascular assessment with contrast-enhanced ultrasound (CEUS) during uterine artery embolisation (UAE): a case report and literature review. J Ultrasound 2020; 24:529-533. [PMID: 32141044 DOI: 10.1007/s40477-020-00441-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2019] [Accepted: 02/21/2020] [Indexed: 02/07/2023] Open
Abstract
The clinical success of uterine artery embolization is determined by its endpoint. An aggressive UAE could lead to endometritis and increases the risk of unintended embolization of other organs. Conversely, an incomplete procedure may result in a poor clinical outcome due to regrowth of the fibroids. We present a case with innovative use of intraoperative contrast-enhanced ultrasonography (CEUS) for the assessment of vascularity of the targeted fibroid to determine the endpoint of embolization perioperatively. We aim to report a case of the use of intraoperative CEUS during UAE to highlight the potential pitfall of its use and provide a review of its application in the literature. Our case affirms the reported usefulness and the practical feasibility to assess the vascularity of fibroids during UAE and highlights that caution should be made by operators in cases of multiple fibroids.

Abstract
Thyroglossal duct cysts (TGDCs) are the most common congenital abnormality of the neck, accounting for approximately 70% of congenital neck lesions. Two-thirds of thyroglossal duct anomalies are diagnosed within the first three decades of life, with more than half being identified before 10 years of age. The age of presentation, clinical examination and imaging are essential for an accurate diagnosis. This review aims to summarize the imaging findings of TGDCs and their main differential diagnoses with emphasis on ultrasound assessment. A focus on site-specific key differentiating between them is also addressed.

Diastasis of rectus abdominis muscles: patterns of anatomical variation as demonstrated by ultrasound. Pol J Radiol 2019; 84:e542-e548. [PMID: 32082453 PMCID: PMC7016498 DOI: 10.5114/pjr.2019.91303] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2019] [Accepted: 11/12/2019] [Indexed: 12/14/2022] Open
Abstract
Purpose The aim of our study was to categorise the anatomical variations of rectus abdominis muscle diastasis (diastasis recti) by using ultrasound (US). Material and methods In a one-year period 92 women were evaluated with US because of suspected diastasis of rectus muscles. Patients were examined in a supine position, with head extended, upper limbs aligned to the trunk, and knees flexed. US was performed with high-frequency, broad-band transducers. Trapezoid field-of-view and extended field-of-view were employed to measure diastasis exceeding 5 cm. Diastasis was defined as a margin-to-margin distance > 20 mm at rest and classified according to the following anatomical patterns: open only above the navel, open only below the navel, open at the navel level, open completely but wider above the navel, and open completely but wider below the navel. Results Diastasis was found in 82 patients (30-61 years old, mean age 35 years). The width was 21-97 mm, mean 39 mm. The prevalence and severity of the anatomical patterns was as follows: open only above the navel in 48 patients (21-88 mm, mean 40 mm), open only below the navel in one patient (33 mm), open at the navel level in seven patients (23-39 mm, mean 34 mm), open completely but wider above the navel in 24 patients (21-97 mm, mean 41 mm), open completely but wider below the navel in two patients (21-29 mm, mean 25 mm). Conclusions The above-navel patterns of recti muscle diastasis are the most common. Even when open completely, diastasis is usually wider above the navel. Knowledge of the anatomical type of rectus muscle diastasis could be of value to the patient (exercises to do and to avoid) and to the surgeon (abdominoplasty planning).

Abstract
BACKGROUND Gastric cancer is the third most lethal malignant tumor worldwide. Metastasis has always been a major cause of poor prognosis. Epidemiological evidence shows that the most common sites for metastasis of gastric carcinoma are the liver (48%), peritoneum (32%), lung (15%), and bone (12%); however, subcutaneous metastasis is are and occurs in approximately 0.8% of cases. We report a rare case of armpit subcutaneous metastasis of gastric cancer. The best surgical window was missed, as a result of lacking attention of the mass.
CASE SUMMARY A 69-year-old man who had previously undergone radical gastrectomy and received eight cycles of oral chemotherapy for gastric cancer showed a rapidly growing mass in his the left armpit; within just 3 mo, the mass grew to a size of 6.9 cm × 4.4 cm × 5.7 cm. Color Doppler ultrasonography and Positron emission tomography/computed tomography prompted the possibility of metastasis of the malignancy. Fine needle aspiration biopsy guided by color Doppler ultrasound showed the presence of cancer cells in the mass. Immunohistochemical examination showed CDX-2 (+), PCK (+), CK20 (+), CK7 (-), and TTF (-), which supported the metastasis of gastric cancer. Considering the risk of resection, the patient did not undergo surgical treatment.
CONCLUSION The case indicates that unidentified subcutaneous masses in patients with a history of gastric cancer should be carefully evaluated.
