Minimally Invasive Image-Guided Percutaneous Irreversible Electroporation of Adrenal Metastases.

Purpose: A single-center retrospective study was performed to evaluate the safety and efficacy of minimally invasive irreversible electroporation (IRE) to treat metastatic adrenal tumors.

Materials And Methods: This single-center study, approved by the Institutional Review Board, retrospectively analyzed six patients who underwent image-guided percutaneous IRE for adrenal metastases. Pre-procedural imaging included CT, MRI and/or F-FDG PET-CT scans.

Irreversible Electroporation in Treating Colorectal Liver Metastases in Proximity to Critical Structures.

Purpose: To evaluate the safety, effectiveness, and oncological outcomes of irreversible electroporation (IRE) of unresectable colorectal liver metastases (CRLMs) close to critical structures.

Materials And Methods: This is a single-center, institutional review board (IRB)-approved, retrospective analysis of patients who underwent percutaneous computed tomography (CT)-guided IRE of CRLM. Between August 2018 and October 2023, 26 patients had 46 tumors treated with percutaneous IRE in 30 ablation sessions.

Intracranial and Extracranial Evaluation.

The vascular lab is an essential tool in diagnosing intracranial and extracranial disease including vasospasm from subarachnoid hemorrhage and carotid artery stenosis in the setting of stroke or transient ischemic attack. This article discusses the indications, protocol, and diagnostic criteria for transcranial doppler (TCD) and carotid artery duplex ultrasound. Intracranial and extracranial arterial testing by way of TCD and carotid imaging carries enormous implications and can provide life or death information.

Abdominal Vascular Evaluation.

The vascular lab (VL) is instrumental in diagnosing vascular diseases such as renal artery stenosis and mesenteric ischemia or following a patient after transjugular intrahepatic portal systemic shunt (TIPS) creation. This article discusses indications, protocol, and diagnostic criteria for abdominal vascular ultrasound. The vascular lab can be used to investigate pathology in the abdomen either as a preliminary screening tool to evaluate for a pathology such as mesenteric artery stenosis in a patient with food fear and weight loss, renal artery stenosis in a patient with refractory hypertension or renal failure, or as a diagnostic tool in follow up after a patient has undergone a transjugular intrahepatic portal systemic shunt (TIPS) for portal hypertension.

The Vascular Lab and the Interventional Radiologist.

A vascular laboratory (VL) can be defined as a place where physicians and technologists have a commitment to perform and interpret non-invasive testing with objective techniques that are most appropriate to the facility and the skills of the laboratory personnel. It provides the entry point for many patients as well as being the sight for diagnosis and follow up for patients with vascular disease for Interventional Radiologists (IRs). VLs may be run by a multi-specialty service, may be hospital-based, or may be private practice-based providing more of a concierge service.

Arterial Evaluation.

The vascular lab (VL) is a powerful tool in diagnosing arterial disease, including peripheral and aortic disease, which is cornerstone of many VLs. This article discusses the indications, protocol, and diagnostic criteria of noninvasive testing for peripheral arterial disease and contrast enhanced ultrasound after endovascular repair of aortic aneurysm.
