Percutaneous treatment of uterine fibroleiomyomas: Analysis of complications and quality of life after embolization

2001

Purpose. To determine the rate complications and the quality of life of patients submitted to uterine artery embolization for the treatment of uterine fibroids. Material and method. Thirty-two women, aged 32-52yrs underwent bilateral embolization of the uterine artery. The patients were affected by menorrhagia (100%) associated with: anaemia in 9 cases, intense menstrual pain in 10 and pressure symptoms in 3. The embolization procedure consisted of selective catheterization of the uterine arteries and injection of embolic particles (PVA). A questionnaire was administered to 27 patients over a period of 4-16 months to evaluate the patients' quality of life after the treatment. Results. The p…

Stent-assisted detachable coil embolization of wide-necked renal artery aneurysms

2017

Renal artery aneurysms (RAAs) are rare with an estimated incidence of 0.1% in the general population, and they represent approximately 25% of all visceral aneurysms. The gold standard of treatment is open surgery, but it is associated with a high risk of nephrectomy, mortality, and morbidity. Less invasive endovascular therapies are becoming increasingly common for the treatment of RAAs. Here, we aimed to report three cases of wide-necked complex renal artery aneurysms treated endovascularly using stent-assisted coil embolization with self-expandable stent nitinol Solitaire AB and Concerto Axium coils. In addition, we describe the use of the waffle-cone technique in a case of wide-necked sa…

A novel NF1 mutation in a pediatric patient with renal artery aneurysm

2022

Abstract Background Neurofibromatosis type 1 (NF1) is a neurocutaneous syndrome, due to heterozygous pathogenic variants in NF1 gene. The main clinical manifestations are multiple café au lait spots, axillary and inguinal freckling, cutaneous and plexiform neurofibromas, optic glioma, Lisch nodules and osseous lesions, such as sphenoid and tibial dysplasia. Vasculopathy is another feature of NF1; it consists of stenosis, aneurysms, and arteriovenous malformations, frequently involving renal arteries. Case presentation We report on a 9-year-old girl with a novel mutation in NF1 gene and renal artery aneurysm, treated by coil embolization and complicated with hypertension. Conclusion Vasculop…

Combined use of uterine artery embolization and local methotrexate injection in interstitial ectopic pregnancies with poor prognosis.

2009

Objective To report three cases of interstitial pregnancies treated successfully by combining uterine artery embolization (UAE) and ultrasound-guided local administration of methotrexate (MTX); and to assess the effect of UAE on ovarian reserve by prospectively measuring serum antimullerian hormone (AMH) levels. Design Case report. Setting Departments of obstetrics and gynecology and radiology of a university hospital. Patient(s) Three patients with interstitial pregnancy. Treatment with multiple IM injections of MTX had failed in cases 1 and 3. Case 2 presented high initial serum β-hCG levels (93,563 mIU/mL), suggesting the presence of a substantial amount of trophoblastic tissue. Interven…

BRONCHIAL ARTERY EMBOLIZATION IN CYSTIC FIBROSIS PATIENTS: A SINGLE CENTRE EXPERIENCE

Management of large dorsal diffuse plexiform neurofibroma

2014

Abstract Neurofibromas are considered one of the hallmark signs of neurofibromatosis type 1(NF1). Diffuse plexiform neurofibroma is a congenital NF1-associated tumor, characterized by overgrowth and interference with function of the affected area. The rich vascular plexus associated with neurofibromas, together with their infiltrative pattern, makes them difficult to eradicate. Complications of neurofibromas are rare but include malignant transformation and potentially lifethreatening hemorrhages. The use of the term “giant” to define a neurofibroma is controversial because there is no clear consensus and descriptions are limited to few case reports. We report a case of a large dorsal diffu…

Imaging-guided interventions modulating portal venous flow: Evidence and controversies

2021

Portal hypertension is defined by an increase in the portosystemic venous gradient. In most cases, increased resistance to portal blood flow is the initial cause of elevated portal pressure. More than 90% of cases of portal hypertension are estimated to be due to advanced chronic liver disease or cirrhosis. Transjugular intrahepatic portosystemic shunts, a non-pharmacological treatment for portal hypertension, involve the placement of a stent between the portal vein and the hepatic vein or inferior vena cava which helps bypass hepatic resistance. Portal hypertension may also be a result of extrahepatic portal vein thrombosis or compression. In these cases, percutaneous portal vein recanalis…

Transgraft sac Embolization Combined with Graft Reinforcement for Refractory Mixed-Type Endoleak.

2018

International audience; An 80-year-old female underwent EVAR 4 years ago. She presented type II endoleak with sac expansion from 68 to 80 mm during 3-year follow-up after EVAR. Although she underwent translumbar percutaneous sac embolization, the AAA sac continued to enlarge, suggesting mixed-type endoleak including type I, II, and III. Transgraft direct sac angiography revealed endoleak cavity without demonstrable feeding vessel. Transgraft sac embolization using n-butyl cyanoacrylate and graft reinforcement was performed concurrently, without complications. The graft reinforcement consisted of graft extension for eliminating occult type I endoleak, and relining for eliminating occult type…

Left atrial thrombi despite anticoagulant and antiplatelet therapy

1994

To investigate risk factors for embolization in patients with echocardiographically detected left atrial thrombi and to evaluate thrombus development, we examined 29 patients with transesophageal and transthoracic echocardiography at two points during a follow-up of 18 months. We compared patients with a history of possible arterial embolization (n = 13) with those without (n = 16) in regard to age, gender, left atrial dilatation, localization of the thrombus in the left atrial cavity, spontaneous echo contrast, and atrial fibrillation. Eight patients were treated with aspirin, 20 with phenprocoumon. Only left atrial spontaneous contrast was associated with thromboembolism (10/15 patients w…

Treatment of hepatocellular carcinoma: A systematic review of randomized controlled trials

1997

Summary Background Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death. Many treatments have been proposed but considerable uncertainty still remains about their effectiveness. In this review we evaluated the quality, clinical coherence, consistency and results of Randomized Controlled Trials (RCT) of non-surgical treatments for HCC. Methods Thirty-seven RCTs examining the effect of different treatments were retrieved using MEDLINE (November 1978 to December 1995) and a review of reference lists. Selected aspects of the quality of design, conduct and reporting were examined. The odds ratio for the probability of surviving up to one year was calculated according to the …
