Title: Is Celiac Trunk Revascularization Necessary After High-Flow Pancreaticoduodenal Arterial Arcades Aneurysm Retrograde Embolization?

High-flow pancreaticoduodenal artery (PDA) aneurysms secondary to celiac trunk occlusion or stenosis have a high risk of rupture. Embolization offers a less invasive alternative to surgery. We evaluated the effectiveness and safety of retrograde embolization via the superior mesenteric artery of high-flow PDA aneurysms without celiac trunk revascularization.

Arterial embolization for massive bleeding from a locally advanced breast tumor.

Advances in breast cancer treatment have markedly reduced the incidence of massive bleeding, yet severe hemorrhage remains a critical issue in locally advanced or metastatic cases. Traditional management strategies often prove inadequate for significant bleeding, highlighting the need for alternative interventions. We detail the management of a 64-year-old patient with a neglected locally advanced breast tumor, leading to life-threatening hemorrhage.

Radiofrequency Combined with Intratumoral Immunotherapy: Preclinical Results and Safety in Metastatic Colorectal Carcinoma.

Radiofrequency ablation (RFA) of cancer induces an anti-tumor immunity, which is insufficient to prevent recurrences. In mice, RFA-intratumoral immunotherapy by granulocyte-macrophage colony-stimulating factor (GM-CSF) and Bacillus Calmette-Guerin resulted in complete metastases regression. Infectious risk in human needs replacement of live vaccines.

Endovascular Management of Life-Threatening Hemoptysis in Primary Lung Cancer: A Retrospective Study.

Objective: The aim of this study was to evaluate the efficacy and safety of endovascular treatment of hemoptysis caused by primary lung cancer.

Methods: We conducted a single-center retrospective study (2005-2021), including patients who underwent thoracic embolization for life-threatening hemoptysis complication of lung cancer. Exclusion criteria were hemoptysis caused by a benign lung tumor or by a lung metastasis of a primary non-lung tumor.

Psoas muscle index is not representative of skeletal muscle index for evaluating cancer sarcopenia.

Background: A common method for diagnosing sarcopenia involves estimating the muscle mass by computed tomography (CT) via measurements of the cross-sectional muscle area (CSMA) of all muscles at the third lumbar vertebra (L3) level. Recently, single-muscle measurements of the psoas major muscle at L3 have emerged as a surrogate for sarcopenia detection, but its reliability and accuracy remain to be demonstrated.

Methods: This prospective cross-sectional study involved 29 healthcare establishments and recruited patients with metastatic cancers.

Strategies to safely rule out pulmonary embolism in COVID-19 outpatients: a multicenter retrospective study.

Objectives: The objective was to define a safe strategy to exclude pulmonary embolism (PE) in COVID-19 outpatients, without performing CT pulmonary angiogram (CTPA).

Methods: COVID-19 outpatients from 15 university hospitals who underwent a CTPA were retrospectively evaluated. D-Dimers, variables of the revised Geneva and Wells scores, as well as laboratory findings and clinical characteristics related to COVID-19 pneumonia, were collected.

Safeness of Simultaneous Colonic Resection and Hepatic Radiofrequency Ablation.

Background And Objectives: Previous reports showed an increased risk of infectious complications when liver radiofrequency ablation (RFA) is performed simultaneously to colorectal resection. The aim of this study was to compare early and long-term outcomes of simultaneous versus staged strategy.

Methods: Data from colorectal cancer liver metastases consecutively treated by surgery of the primary tumor with an associated liver RFA procedure between January 1, 2010 and January 31, 2020.

Contemporary Outcomes for the Curative Treatment of Colorectal Cancer Pulmonary Metastases.

Purpose: Treatment of pulmonary metastases (PM) from colorectal cancer (CRC) is the standard of care by several guidelines from Europe and the USA, but the validity of this strategy has been recently questioned, and the available evidence supporting this strategy is weak. We report the outcomes of a curative intent strategy in a very recent and homogenous series of patients.

Methods: We did a retrospective review of all curative intent surgical or ablative treatment of PM from CRC performed consecutively in 3 French institutions from January 2015 to December 2019.

Endovascular treatment of haemorrhagic pancreatic serous cystadenoma.

Background: Pancreatic microcystic serous cystadenoma are rare benign pancreatic tumors. No treatment is needed in most cases as this lesion is often discovered incidentally. Surgery is not required except in symptomatic cases.

Myocardial Infarction in a 29-Year-Old Woman Leads to Diagnosis and Treatment of a Rare Disease.

A 29-year-old woman without history of cardiac disease or risk factors sought treatment for sudden onset of chest pain radiating down the back, jaw, and arms, complicated by discomfort in the orthostatic position and severe headache. She had a history of epistaxis since childhood as well as familial history of epistaxis via her mother. BMI was 22 kg/m, and electrocardiography showed ST segment depression in V1V2 precordial leads and T-wave inversion in inferior leads.

Thrombosis of Medium-Sized and Large Arteries During Covid-19 Infection: Results of the COVIVASC Study.

Background: COVID-19 infection is associated not only with venous thromboses but also with arterial thromboses (COV-ATs) in relation with an endothelial dysfunction, a coagulopathy and rhythm disorders. The incidence, the topography, and the prognosis of COV-ATs remain poorly known. The objective of this study was to report the overall experience of the Greater Paris University Hospitals (Assistance Publique - Hopitaux de Paris, AP-HP) during the first pandemic wave of COVID-19 infection.

Ruptured Intercostal Artery Aneurysm with Radiculomedullary Branch Downstream Treated with Endovascular Stenting.

Intercostal artery aneurysms are extremely rare, and could be associated with aortic coarctation, systemic diseases like neurofibromatosis, or more rarely Marfan syndrome. They could be life-threatening when ruptured, leading to hemothorax or mediastinal hematoma. Endovascular management before or after rupture of intercostal aneurysms, should be considered.

Contribution of Interventional Radiologist in the Management of Pseudoaneurysm and Neck Hemorrhages in COVID-19 patients.

Patients with severe coronavirus disease 2019 (COVID-19) may have endothelial inflammation, pseudoaneurysm, and an increasing risk of bleeding, especially during surgical procedures. In this article, we reported 2 cases of COVID-19 patients with neck vascular lesions. The first patient had pseudoaneurysm of the cricothyroid artery, which was treated by percutaneous glue injection through ultrasonography guidance.

Analysis of inspiratory and expiratory muscles using ultrasound in rats: A reproducible and non-invasive tool to study respiratory function.

Ultrasound imaging is a non-invasive technique to assess organ function. Its potential application in rodents to evaluate respiratory function remains poorly investigated. We aimed to assess and validate ultrasound technique in rats to analyze inspiratory and expiratory muscles.

phenotype overlaps with hereditary haemorrhagic telangiectasia: two case reports.

Background We report two cases of -related capillary malformation-arteriovenous malformation (CM-AVM1) syndrome mimicking hereditary haemorrhagic telangiectasia (HHT).Methods and results A 28-year-old man, previously embolised for cerebral arteriovenous malformations (AVMs), presented with epistaxis and typical nasal telangiectasias of HHT. CT scan revealed a large portocaval shunt.

18-FDG PSEUDOTUMORAL LESION WITH QUICK FLOWERING TO A TYPICAL LUNG CT COVID-19.

As coronavirus pandemic continues to spread over the world, physicians have to be aware of atypical features of COVID-19 pneumonia. We report the case of a 78-year-old man presenting with pseudo-tumoral focal lesion of the left lung which switched shortly to severe and diffuse COVID-19 induced pneumonia. Nuclear medicine physicians and radiologists should be careful of some misleading hypermetabolic aspects mostly in asymptomatic patients.

[Relevance of a catheter team for short stays with elderly people].

Elderly patients hospitalized in acute care service very often have a weakened venous tissue which, in the case of medium-term intravenous treatment, leads to multiple painful punctures. In order to alleviate this major inconvenience, within the framework of a cooperation protocol, a catheter team was trained in the ultrasound-guided insertion of the appropriate catheter for the management of geriatric patients.

Higher prevalence of splenic artery aneurysms in hereditary hemorrhagic telangiectasia: Vascular implications and risk factors.

Background: Splenic artery aneurysm (SAA) is a rare but potentially fatal condition. Rupture results in 25% mortality up to 75% in pregnant women with 95% fetal mortality. Brief reports suggest an increased risk of developing SAA in patients with HHT.

Pulmonary gas exchange in hereditary hemorrhagic telangiectasia patients with liver arteriovenous malformations.

Background: The severity of Hereditary Hemorrhagic Telangiectasia (HHT) disease is generally related to vascular visceral involvement represented by arteriovenous malformations (AVMs). Pulmonary function tests (PFTs) remain normal in HHT patients without Pulmonary AVMs (PAVMs) and respiratory comorbidity. The aim of our study was to compare the diffusing capacity of the lung for carbon monoxide (D) and nitric oxide (D) and its 2 components: the pulmonary capillary blood volume (Vc) and the alveolar-capillary membrane conductance (Dm), in HHT patients with PAVMs, PAVMs and liver AVMs (LAVMs), LAVMs without PAVM, no PAVM and LAVM, and controls.
