A technical review of percutaneous sclerotherapy with bleomycin for giant hepatic venous malformation.

Background: Hepatic venous malformation (HVM), traditionally called liver haemangioma, is considered the most common benign hepatic lesion. Treatment might be indicated in large and symptomatic HVMs. We aim to describe stepwise technical aspects of trans-hepatic percutaneous sclerotherapy of hepatic venous malformation (HVM).

Percutaneous Sclerotherapy for Budd-Chiari Syndrome Secondary to Giant Hepatic Venous Malformations (Hemangiomas).

This prospective study evaluated the safety and effectiveness of percutaneous sclerotherapy in the treatment of secondary Budd-Chiari syndrome due to hepatic venous malformations (HVMs). Four patients (mean age, 40 years; 3 women) with 5 HVMs underwent 7 sessions of percutaneous sclerotherapy with a mixture of bleomycin and lipiodol. All patients had chronic Budd-Chiari syndrome, determined based on imaging findings, with the main symptom being abdominal discomfort and distention.

Balloon-occluded antegrade transvenous obliteration of rectal varices: A case report.

Patients with liver cirrhosis frequently experience rectal variceal bleeding subsequent to portal hypertension. Unlike gastroesophageal variceal bleeding, a well-established guideline does not exist in terms of management of bleeding rectal varices. A 75-year-old male with non-alcoholic-steatohepatitis induced cirrhosis presented with a 3-day history of severe rectorrhagia.

Percutaneous Sclerotherapy with Bleomycin and Ethiodized Oil: A Promising Treatment in Symptomatic Giant Liver Hemangioma.

Background Percutaneous sclerotherapy with bleomycin has been proven to have a potential benefit in the management of low-flow venous malformations. Liver hemangiomas are considered low-flow venous malformations. Thus, percutaneous sclerotherapy could potentially have a promising result in their management.

Successful vascular interventional management of superior mesenteric vein thrombosis in a patient with COVID-19: A case report and review of literature.

Coronavirus disease (COVID-19) is associated with thrombosis formation in various vessels, including those in the abdomen. In this case report, we present a COVID-19 infected patient who had developed abdominal discomfort. The patient underwent magnetic resonance imaging, which showed signs of thrombosis formation in the superior mesenteric vein (SMV).

Intractable parastomal bleeding in a portal hypertensive patient managed by direct sclerotherapy: a case report.

Patients with a stoma have 5% chance of developing parastomal varices, which tend to repetitive massive and life-threatening hemorrhages. Treatment of choice in parastomal varices have not been established, while Transjugular Intrahepatic Portosystemic Shunt (TIPS) has been revealed as the most successful measure. We report a hemodynamically unstable patient with a history of Ulcerative Colitis (UC) and Primary Sclerosing Cholangitis (PSC) with colostomy, because of colon cancer who presented with massive parastomal bleeding.

Application of Microwave Ablation for Treating Pulmonary Adenocarcinoma: A Case Report.

Pulmonary metastases occasionally do not respond to chemotherapy and surgery. Moreover, some early stage cancer patients, who are candidates for surgery, are unable to tolerate surgery. In such cases, microwave ablation is a convenient alternative for tumor eradication.

Percutaneous Sclerotherapy for Giant Symptomatic Liver Hemangiomas: A Pilot Study.

This single-center prospective trial evaluated the safety and efficacy of percutaneous sclerotherapy for liver hemangiomas in 5 patients (1 man, 4 women; mean age 41.2 y) between 2016 and 2017. All patients were symptomatic (4 abdominal pain; 1 early satiety) and refused surgery.

The relationship between total mass and blood supply of parathyroid glands and their secretion of parathyroid hormone in hemodialysis patients with secondary hyperparathyroidism.

Characteristics of parathyroid glands usually determined by ultrasonography such as its total weight or volume might be a good indicator for the induction or suppression of parathyroid hormone (PTH) secretion from these glands. In the present study, we investigated the relationship between the volume and blood supply grade of the parathyroid glands, and its PTH secretion. Study subjects included 52 consecutive patients with the secondary hyperparathyroidism undergoing maintenance hemodialysis therapy referred to dialysis wards of the Imam Khomeini and Amiralam University Hospitals in Tehran.

Coil Embolotherapy of Unilateral Diffuse Pulmonary Arteriovenous Malformations in a Nineteen-Year-Old Woman.

Pulmonary arteriovenous malformations (AVMs) are rare vascular malformations of the lung that usually led to a notable risk of serious and life-threatening complications. There is considerable debate about the best management of strategies for the group of patients with diffuse AVMs. Several therapeutic options have been reported for management of this abnormality among which coil embolization is currently the preferred ones.

Renal Sympathetic Denervation by CT-scan-Guided Periarterial Ethanol Injection in Sheep.

Background: Renal nerves are a recent target in the treatment of hypertension. Renal sympathetic denervation (RSD) is currently performed using catheter-based radiofrequency ablation (RFA) and because this method has limitations, percutaneous magnetic resonance (MR)-guided periarterial ethanol injection is a suggested alternative. However, few studies have been conducted on the effectiveness of percutaneous ethanol injection for RSD.

Peripheral venous malformations with a dominant outflow vein: results of ethanol embolization.

Venous malformations are the most common form of symptomatic vascular malformations. VM s could classify into low-flow lesions (VMs) and high-flow lesions (AVMs). For low-flow venous lesions, direct percutaneous puncture with injection of sclerosing agents (sclerotherapy) has been described as a successful therapy.

Contribution of stone size to chronic kidney disease in kidney stone formers.

Objectives: To determine whether stone burden correlates with the degree of chronic kidney disease in kidney stone formers.

Methods: A total of 97 extracorporeal shockwave lithotripsy candidates aged 18 years and older were included. Size, number and location of the kidney stones, along with cumulative stone size, defined as the sum of diameters of all stones) were determined.

In 2001, a Liver Transplantation (LT) program was commenced in Imam Khomeini Hospital Complex as the first one in the capital city of Tehran which is the second liver transplantation center in Iran. This study presents the results of our 10-year experience with LT.

Intraosseous Lipoma of the Femor: Image Findings.

Introduction: Intraosseous lipoma is a rare benign bone disease. Long and cancellous bones are the most locationsthat can be affected. Almost all lesions were discovered incidentally on imaging modalities that were done during an unrelated investigation.

Successful catheter-directed venous thrombolysis in an ankylosing spondylitis patient with phlegmasia cerulea dolens.

Ankylosing spondylitis (AS) is an inflammatory rheumatic disease. Phlegmasia cerulea dolens is a severe form of deep vein thrombosis characterized by swelling, pain, and bluish discoloration. Treatment delay may cause venous gangrene, tissue ischemia, limb loss or death.

Color Doppler indices of orbital arterial flow in end-stage renal disease patients; are the changes related to chronic hemodialysis or chronic renal failure?

Background: Endothelial injury is a well-known complication in chronic kidney disease (CKD) and hemodialysis. One of the sites in which early vascular changes may be detected is the retina. Of course, these flow changes may not be detected in ophthalmologic exams, but it seems that color Doppler sonography of retinal arteries may be helpful in these cases.

Diffusion-weighted magnetic resonance imaging for diagnosis of liver fibrosis and inflammation in chronic viral hepatitis: the performance of low or high B values and small or large regions of interest.

Objective: To investigate the performance of different b values and regions of interest (ROI) for diagnosing liver fibrosis in patients with chronic viral hepatitis by using diffusion-weighted (DW) magnetic resonance imaging (MRI).

Methods: Eleven healthy participants and 33 patients with viral hepatitis B or C were enrolled. The stage of liver fibrosis and the grade of necroinflammation were determined by using a histologic activity index.

Antidepressant effects of magnetic resonance imaging--based stimulation on major depressive disorder: a double-blind randomized clinical trial.

Antidepressant effects of magnetic resonance imaging (MRI) based stimulation have been reported in animal studies, but no human studies are available on subjects with major depressive disorder. Here, the efficacy of two diagnostic MRI protocols (echo-planar diffusion-weighted imaging (DWI) and T1-weighted imaging) was assessed in patients with major depressive disorder. In this double-blind randomized clinical trial, 51 patients with clinically proven major depressive disorder were randomly enrolled into three equal groups.

Transcatheter embolization of congenital hepatic arteriovenous malformation using ethylene-vinyl alcohol copolymer (Onyx).

A male infant with high-output heart failure who had been found to have a hepatic arteriovenous malformation by ultrasound imaging was referred to our center (Department of Diagnostic and Interventional Radiology, Imam Khomeini Hospital, Tehran University of Medical Sciences, Islamic Republic of Iran) for further evaluation. Computed tomography angiography revealed a large hepatic arteriovenous malformation with feeders originating from enlarged hepatic arteries and draining to enlarged hepatic veins. We performed a transcatheter embolization of the anomaly using ethylene vinyl alcohol copolymer (Onyx) during a single session.

Depiction of the gall bladder (GB), cystic duct (CD), proximal and distal parts of the common bile duct (CBD), intrahepatic ducts (IHD), ampulla of vater (AV), main pancreatic duct (MPD) and signal loss of stomach and three different segments of the duodenum were investigated according to VAS and Likert scores.

A review on dural tail sign.

"Dural tail sign" (DTS) which is a thickening of the dura adjacent to an intracranial pathology on contrast-enhanced T1 MR Images, was first thought to be pathognomonic of meningioma, however, many subsequent studies demonstrated this sign adjacent to various intra- and extra-cranial pathologies and in spinal lesions. In this paper we outline the history, accompanying pathologies and the differentiation and probable pathophysiology of DTS. We also discuss whether we can predict tumoral involvement of the dural tail before surgery and whether the dural tail adjacent to a tumor should be resected.
