Interventional oncology sets aim on becoming the fourth pillar in the treatment of cancer.
CVO expert Lawrence “Rusty” Hofmann, MD, shares his view of the landscape, plus his crossing techniques and device preferences.
Since the introduction of retrievable filters, our division has kept a database of every patient in whom a retrievable filter was placed by the interventional radiology department. Over the years as we started to learn more about the complications of retrievable filters, we became more aggressive in reaching out to patients for filter retrieval. Today, our database has matured to include more detailed information such as the reason for filter placement, type of retrievable filter, and the referring physician to further improve patient follow-up.
Experts discuss the potential for further investigation of cell therapy for the treatment of PAD/CLI
There are multiple endovascular options for treatment of infrainguinal disease, but treatment of severe calcific disease of the superficial femoral artery (SFA), popliteal artery, and tibial vessels remains a challenge. Peripheral atherectomy is a unique treatment modality because it allows debulking of plaque with luminal gain and minimal barotrauma. This results in less injury to the vessel during initial treatment and theoretically reduces hyperplastic reaction to the initial treatment. In severely calcific vessels, calcium debulking changes the vessel wall compliance with the removal of calcium. It can then be treated with low-pressure balloon inflation with minimal injury to the vessel wall. This is now a particularly attractive concept with the availability of drug-coated balloons and drug-eluting stents, as the vessel can be prepared with atherectomy before delivery of these devices. This may ensure adequate drug delivery to the tissue, thereby reducing intimal hyperplastic reaction and increasing durability of the procedures. Prevailing concerns with atherectomy (ie, dissection, perforation, clinically significant embolization, and durability) have prevented the widespread use of atherectomy.
OBJECTIVE. The purpose of this article is to highlight the clinical and radiologic evaluation of patients referred for transjugular intrahepatic portosystemic shunt (TIPS) creation.
OBJECTIVE. Severe acute respiratory syndrome (SARS) was a highly virulent atypical pneumonia caused by a novel coronavirus that resulted in a pandemic in 2003. Singapore was one of the most severely affected countries, and SARS took a heavy toll on our health care system. The lessons learned during the pandemic have shaped our national contagion response plan and have proved valuable in subsequent epidemics. We describe the lessons learned for the radiology department.
OBJECTIVE. To understand the abdominal aortic aneurysm imaging characteristics that must be accurately described for endovascular aortic aneurysm repair treatment planning, including evaluation of the landing zones, aneurysm morphology, and vascular access.
OBJECTIVE. Lifelong postprocedural imaging surveillance is necessary after endovascular abdominal aortic aneurysm repair (EVAR) to assess for complications of endograft placement, as well as device failure and continued aneurysm growth. Refinement of the surveillance CT technique and development of ultrasound and MRI protocols are important to limit radiation exposure.
OBJECTIVE. The purpose of this article is to review the CT angiographic and digital subtraction angiographic features of the male pelvic arteries.
OBJECTIVE. Transcatheter aortic valve implantation has emerged as a viable treatment alternative for patients with severe aortic stenosis who are not surgical candidates. Multidimensional (3D and 4D) MDCT angiography plays a critical role in the safety, success, and outcome of an institutional transcatheter aortic valve implantation program.
OBJECTIVE. The purpose of this article is to assess and describe the MRI findings after prostatic artery embolization for treatment of benign prostatic hyperplasia.
OBJECTIVE. The purpose of this article is to describe the indications for and approach to image-guided percutaneous ablation of renal tumors.
Purpose: The minimally important difference (MID) represents the smallest change in score on patient-reported outcome measures that is relevant to patients. The aim of this study was to introduce the MID for the Vascular Quality of Life Questionnaire (VascuQol) and the walking impairment questionnaire (WIQ) for patients with intermittent claudication (IC).
Purpose: To compare the impact of proximal or distal splenic artery embolisation versus that of splenectomy on splenic immune function as measured by IgM memory B cell levels.
