Partial biochemical response of adrenal artery embolization for pheochromocytoma: A case report and review of the literature.

We present the case of a 22-year-old male with a left adrenal pheochromocytoma, initially diagnosed during a workup for thoracic pain. The patient's tumor was refractory to medical management, and surgical resection was ruled out due to high cardiovascular risk, stemming from cyanotic congenital heart disease, aortic aneurysm, and factor VII deficiency. The patient underwent adrenal artery embolization (AAE) as a salvage treatment.

Conventional and Contrast-enhanced US of the Lung: From Performance to Diagnosis.

In recent years, lung US has evolved from a marginal tool to an integral component of diagnostic chest imaging. Contrast-enhanced US (CEUS) can improve routine gray-scale imaging of the lung and chest, particularly in diagnosis of peripheral lung diseases (PLDs). Although an underused tool in many centers, and despite inherent limitations in evaluation of central lung disease caused by high acoustic impedance between air and soft tissues, lung CEUS has emerged as a valuable tool in diagnosis of PLDs.

Continuous positive airway pressure is unsafe for radiofrequency ablation of lung cancer under sedation: a randomised controlled trial.

Objective: To evaluate the safety of a minimum continuous positive airway pressure of 4 cmHO (CPAP + 4) during computed tomography (CT)-guided radiofrequency ablation (RFA) for lung malignancies under procedural sedation and analgesia (PSA).

Methods: This was a prospective, randomised, single-blind, parallel-group, placebo-controlled trial with an open-label medical device conducted at a single tertiary university hospital in Barcelona, Spain. Forty-six patients over 18 years of age scheduled for CT-guided RFA of a malignant pulmonary tumour under PSA were randomised to receive either CPAP + 4 or a modified mask for placebo CPAP (Sham-CPAP).

Minimizing neurovascular complications during image-guided percutaneous cryoablation of a cervical spinal aneurysmal bone cyst using protective doxycycline sclerotherapy: a case report.

Background: Aneurysmal bone cysts (ABC) are rare, locally aggressive bone tumors primarily observed in pediatric patients. Surgical curettage is the treatment of choice. Image-guided percutaneous cryoablation (CYOA) is a recently implemented alternative technique in cases not amenable to surgery.

Imaging of chronic thromboembolic pulmonary hypertension before, during and after balloon pulmonary angioplasty.

Balloon pulmonary angioplasty (BPA) has recently been elevated as a class I recommendation for the treatment of inoperable or residual chronic thromboembolic pulmonary hypertension (CTEPH). Proper patient selection, procedural safety, and post-procedural evaluation are crucial in the management of these patients, with imaging work-up playing a pivotal role. Understanding the diagnostic and therapeutic imaging algorithms of CTEPH, the imaging features of patients amenable to BPA, all imaging findings observed during and immediately after the procedure and the changes observed during the follow-up is crucial for all interventional radiologists involved in the care of patients with CTEPH.

Clinicopathological and Neuroimaging Features of Primary Gliosarcoma: A Case Series and Review of Literature.

Background: Gliosarcoma (GS) is a rare primary high-grade brain neoplasm with a poor prognosis and challenging surgical resection. Although it is now considered a morphologic variant of IDH-wildtype glioblastoma (World Health Organization Classification of Tumours 2021), GS may display peculiarities that hamper both surgical and oncological management.

Methods: In this retrospective study, we searched our registry for histologically confirmed GS patients between 2006 and 2020.

Percutaneous transhepatic biliary drainage for biliary obstruction in perihilar cholangiocarcinoma: a 10-year analysis of safety and outcomes using the CCI index.

Purpose: To evaluate percutaneous transhepatic biliary drainage (PTBD) safety and efficacy in patients with perihilar cholangiocarcinoma (PCCA).

Methods: This retrospective observational study included patients with PCCA and obstructive cholestasis referred for a PTBD in our institution between 2010 and 2020. Technical and clinical success rates and major complication and mortality rates one month after PTBD were used as main variables.

Preoperative localization of lung nodules: a comparative analysis of hookwire and radio-guided procedures.

Background: Histological diagnosis of pulmonary nodules requires surgical resection on many occasions. There are multiple localization strategies each with their own benefits and complications. The objective of this study is to compare preoperative lung nodule localization with hookwire and radiotracer injection (radioguided occult lesion localization, ROLL).

Persistent lymph nodes after curative chemoradiotherapy for head and neck cancer: imaging predictors of response for decision-making.

Purpose: To identify response predictors in patients with head and neck squamous cell carcinoma (N + HNSCC) and persistent lymph nodes after curative chemoradiotherapy treatment (CCRT).

Materials And Methods: Consecutive patients with N + HNSCC treated with CCRT and persistent lymph nodes at first follow-up between 2015 and 2021 were identified and analyzed. Complete response was defined as the absence of lymph node metastatic involvement in patients with salvage lymphadenectomy or the absence of progression after 1 year of successive follow-ups.

Optimal Timing for Cardiac Surgery in Infective Endocarditis with Neurological Complications: A Narrative Review.

In patients with infective endocarditis and neurological complications, the optimal timing for cardiac surgery is unclear due to the varied risk of clinical deterioration when early surgery is performed. The aim of this review is to summarize the best evidence on the optimal timing for cardiac surgery in the presence of each type of neurological complication. An English literature search was carried out from June 2018 through July 2022.

Derivo embolization device for intracranial aneurysms: a Spanish multicenter retrospective study.

Background: Flow diverters have emerged in recent years as a safe and effective treatment for intracranial aneurysms, with expanding indications. The Derivo embolization device (DED) is a second-generation flow diverter with a surface finish that may reduce thrombogenicity. We report our multicenter experience evaluating its safety and efficacy.

Oral hydration as a safe prophylactic measure to prevent post-contrast acute kidney injury in oncologic patients with chronic kidney disease (IIIb) referred for contrast-enhanced computed tomography: subanalysis of the oncological group of the NICIR study.

Background: T he objective of this study is to evaluate oral hydration compared to intravenous (i.v.) hydration in the prevention of post-contrast acute kidney injury (PC-AKI) in the oncologic subgroup of patients with stage IIIb chronic kidney disease (CKD) included in the NICIR study referred for elective contrast-enhanced computed tomography (CE-CT).

Image-guided percutaneous ablation for the treatment of lung malignancies: current state of the art.

Image-guided percutaneous lung ablation has proven to be a valid treatment alternative in patients with early-stage non-small cell lung carcinoma or oligometastatic lung disease. Available ablative modalities include radiofrequency ablation, microwave ablation, and cryoablation. Currently, there are no sufficiently representative studies to determine significant differences between the results of these techniques.

Oral hydration compared to intravenous hydration in the prevention of post-contrast acute kidney injury in patients with chronic kidney disease stage IIIb: A phase III non-inferiority study (NICIR study).

Objective: To evaluate the non-inferiority of oral hydration compared to intravenous (i.v.) hydration in the prevention of post-contrast acute kidney injury (PC-AKI) in patients with stage IIIb chronic kidney disease (CKD) referred for an elective contrast-enhanced computed tomography (CE-CT).

Arterio-biliary fistula caused by a hepatic artery pseudoaneurysm in a recently performed liver transplant: successful resolution and long-term liver implant preservation using a covered coronary stent.

Background: The formation of a hepatic artery pseudoaneurysm in a liver implant is a rare but potentially fatal complication. Fistulization of such pseudoaneurysms into the bile duct is sporadic. The most common causes of hepatic artery pseudoaneurysm are infection at the anastomosis site, inadequate surgical technique, and an iatrogenic origin due to minimally invasive procedures.
