Purpose: To determine whether celiac ganglion block can serve as a diagnostic test for dysautonomia as the cause of gastrointestinal dysmotility-related symptoms.

Materials And Methods: This was an institutional review board-approved, prospective, single-arm, registered study, from January 2020 to May 2021, and included patients aged 14-85 years with gastrointestinal symptoms of food intolerance, abdominal pain, or angina. Patients with nonneurogenic causes (ie, chronic cholecystitis, peptic ulcer disease, gastroesophageal reflux, and malabsorption syndrome) were excluded.

Spontaneous breast hematoma as a complication of anticoagulation therapy requiring angiography and embolization.

Spontaneous breast hematoma is a rare complication of therapeutic anticoagulation therapy with few cases reported in the literature. We present a case of spontaneous breast hematoma resulting in hypotension and symptomatic anemia. Angiography demonstrated multiple sites of hemorrhage within the breast, which was treated with gelatin sponge embolization.

Percutaneous Cryoablation for Stage 1 Renal Cell Carcinoma: Outcomes from a 10-year Prospective Study and Comparison with Matched Cohorts from the National Cancer Database.

Background Percutaneous cryoablation (PCA) is an increasingly utilized treatment for stage I renal cell carcinoma (RCC), albeit without supportive level I evidence. Purpose Primary objective was to determine the 10-year oncologic outcomes of PCA for stage I RCC in a prospective manner. Secondary objectives were to compare outcomes after partial nephrectomy (PN) and radical nephrectomy (RN) from the National Cancer Database (NCDB), to determine long-term renal function, and to determine the risk of metachronous disease.

Adrenal vein sampling with and without cosyntropin stimulation for detection of surgically remediable aldosteronism.

Context And Objective: Bilateral adrenal vein sampling (AVS), the diagnostic standard for identifying surgically remediable aldosteronism (SRA), is commonly performed after cosyntropin stimulation (post-ACTHstim). The role of AVS without cosyntropin stimulation (pre-ACTHstim) has not been established. The selectivity index (SI), the adrenal vein (av) serum cortisol concentration divided by that in a peripheral vein, confirms av sampling.

Single 15-Min Protocol Yields the Same Cryoablation Size and Margin as the Conventional 10-8-10-Min Protocol: Results of Kidney and Liver Swine Experiment.

Introduction: The objective was to determine the ablation size of a single 15-min freeze and compare it with the conventional 10-min freeze-8-min thaw-10-min freeze protocol. Secondary objectives were to determine the ablation margin and to ascertain whether islands of viable tissue remain within the ablation zone.

Materials And Methods: Five adult swine under general anesthesia were used.

CT-Guided, Percutaneous Ethanol Sympatholysis for Primary Hyperhidrosis.

Purpose: Primary hyperhidrosis (PH) typically involves the craniofacial (CF) or axillary-palmar (AP) region. Our purpose was to determine the safety and efficacy of CT-guided sympatholysis for treating PH.

Methods: In this prospective study, 39 consecutive patients with CF or AP PH were referred for percutaneous sympatholysis.

Resolution of generalized compensatory hyperhidrosis related to sympathectomy, after T2 sympatholysis.

Compensatory hyperhidrosis (CH) is common after sympathectomy, and most treatments are ineffective. We present a 36-year-old man whose CH was effectively treated with percutaneous sympatholysis. The patient's axillary-palmar hyperhidrosis had been treated with T3-4 sympathetic ligation.

Kidney Cancer.

The number of new cases of renal cell carcinoma has been steadily increasing since the 1960s, reaching 62,000 and 89,000 annually in the United States and Europe, respectively, in 2016. The current standard of care for early-stage disease is nephron-sparing surgery, which has a demonstrated long-term disease-free survival and an acceptable safety profile. Technical developments (thin, powerful probes and real-time image guidance systems) have allowed image-guided percutaneous ablation to become a viable option for stage I renal cell carcinoma.

Hemorrhagic Complications of Percutaneous Cryoablation for Renal Tumors: Results from a 7-year Prospective Study.

Purpose: Cryoablation of renal tumors is assumed to have a higher risk of hemorrhagic complications compared to other ablative modalities. Our purpose was to establish the exact risk and to identify hemorrhagic risk factors.

Materials And Methods: This IRB approved, 7-year prospective study included 261 renal cryoablations.

Extramedullary hemopoiesis.

Various chronic hematologic disorders that lead to ineffective hemopoiesis or inadequate bone marrow function (ie, chronic hemolytic anemias, thalassemia, sickle cell anemia, myelofibrosis of many causes, lymphoma, and leukemia) can potentially precipitate extramarrow new blood element creation. Extramarrow soft tissue that produces blood elements is called extramedullary hemopoietic tissue and the process extramedullary hemopoiesis (EMH). Sites commonly involved by EMH include the liver, spleen, lymph nodes, and most commonly, paravertebral regions, although other sites can sometimes be involved.

Amyloidosis: review and imaging findings.

Amyloidosis is a collection of pathophysiologically related disease entities caused by the extracellular deposition of abnormal fibrillar proteins called amyloid. The accumulation of amyloid may be systemic, involving many organs, or localized manifesting as infiltration of individual organs, or in the form of a focal, tumorlike lesion. Amyloidosis may develop in the setting of underlying conditions, usually chronic inflammatory diseases, in which case it is termed secondary, or it may involve no underlying disease and thus be primary or idiopathic.

Efficacy and safety of percutaneous cryoablation for stage 1A/B renal cell carcinoma: results of a prospective, single-arm, 5-year study.

Purpose: Percutaneous cryoablation is gaining in popularity as a viable treatment option for renal cell carcinoma (RCC). We present the 5-year oncologic outcomes of a prospective trial.

Methods: Over a 5-year period, we treated 134 consecutive patients with biopsy-proven RCC with CT-guided percutaneous cryoablation.

Renal function and oncologic outcomes after cryoablation or partial nephrectomy for tumors in solitary kidneys.

Purpose: Preservation of renal function is of paramount importance in patients with tumors in solitary kidneys. We compared the renal function and oncologic outcomes of patients treated by partial nephrectomy with those of patients treated by cryoablation for solitary kidney tumors.

Materials And Methods: All patients with solitary kidneys who were treated for renal tumors at our institution between 1997 and 2007 were included in the screen.

Chemoembolization decreases drop-off risk of hepatocellular carcinoma patients on the liver transplant list.

Introduction: The drop-off risk for patients awaiting liver transplantation for hepatocellular carcinoma (HCC) is 22%. Transplant liver availability is expected to worsen, resulting in longer waiting times and increased drop-off rates. Our aim was to determine whether chemoembolization can decrease this risk.

Complications of renal cryoablation: a single center experience.

Purpose: We describe perioperative complications associated with renal cryoablation and identify potential risk factors for certain complications.

Materials And Methods: We retrospectively analyzed the medical records of patients with unifocal renal masses treated with cryosurgery at a single center between 1997 and 2007. All complications associated with these procedures were documented and classified into grades 1 to 5 by the Clavien surgical complication classification.

Nonresectable hepatocellular carcinoma: long-term toxicity in patients treated with transarterial chemoembolization--single-center experience.

Purpose: To determine the toxicity profile of transarterial chemoembolization (TACE) at 6 months and 1 year after treatment in patients with hepatocellular carcinoma (HCC) in a standardized oncology protocol so that TACE could be compared with systemic chemotherapeutic regimens for liver cancer.

Materials And Methods: The study was authorized by the institutional review board. Between January 2002 and January 2007, 190 patients (155 men, 35 women; median age, 65 years; age range, 18-84 years) with HCC who underwent TACE treatment were identified from a prospectively collected database.

Chemoembolization of hepatic metastases from ocular melanoma: assessment of response with contrast-enhanced and diffusion-weighted MRI.

Objective: The purpose of this study was to assess the utility of assessment of tumor size and enhancement with diffusion-weighted and conventional MRI in the evaluation of response to transarterial chemoembolization therapy for metastatic ocular melanoma.

Conclusion: In patients with ocular melanoma and liver metastasis treated with transarterial chemoembolization, functional MRI showed significant changes in the lesions. These changes included a decrease in tumor enhancement and an increase in the apparent diffusion coefficient of the tumor, suggesting increasing tumor necrosis and cell death.

Role of functional magnetic resonance imaging in assessing metastatic leiomyosarcoma response to chemoembolization.

Purpose: To assess the value of functional magnetic resonance (MR) imaging in the evaluation of early tumor response after transarterial chemoembolization (TACE) for metastatic leiomyosarcoma and compare tumor response using functional MR imaging versus traditional imaging response assessment, which is based on tumor size.

Materials And Methods: We evaluated 31 lesions in 10 patients with liver metastases from leiomyosarcoma using MR imaging studies before and after TACE. Diffusion and contrast-enhanced MR imaging was performed on a 1.
