Some colorectal cancer (CRC) patients present symptoms of bowel obstruction, which is considered a surgical emergency. Because of poor medical condition and high incidence of post-surgical complications, there has been increasing use of self-expanding metal stents (SEMS) for the purpose of palliation or as a bridge to surgery with some benefits, including shorter hospital stays, lower rates of adverse events, and one-stage surgery. However, with increasing survival of CRC patients, there have been controversial data on clinical outcomes and complications, compared between SEMS use and surgery for treatment of malignant bowel obstruction. We review recent clinical data on clinical outcomes of SEMS use compared to surgery, including complications.
Hepatocellular carcinoma (HCC) is one of the most common malignant diseases worldwide. While curative therapies, including resection, liver transplantation, and percutaneous ablation (percutaneous ethanol injection and radiofrequency ablation), are applicable for only a portion of the HCC population, transcatheter arterial chemoembolization (TACE) has been recognized as an effective palliative treatment option for patients with advanced HCC. TACE is also used even for single HCCs in which it is difficult to perform surgical resection or locoregional treatment due to systemic co-morbidities or anatomical problems. TACE has become widely adopted in the treatment of HCC. By using computed tomography-angiography, TACE is capable of performing diagnosis and treatment at the same time. Furthermore, TACE plays an important role in the multidisciplinary treatment for HCC when combined with other treatment. In this review, we first discuss the history of TACE, and then review the previous findings about techniques of achieving a locoregional treatment effect (liver infarction treatment, e.g., ultra-selective TACE, balloon-occluded TACE), and the use of TACE as a drug delivery system for anti-cancer agents (palliative, e.g., platinum complex agents, drug-eluting beads) for multiple lesions.
The purpose of the study was to retrospectively compare technique effectiveness of computed tomography (CT)-guided versus magnetic resonance (MR)-guided radiofrequency (RF) ablation of hepatocellular carcinoma (HCC).
Liver metastasis from a neuroendocrine tumour (NET) represents a significant clinical entity. A multidisciplinary group of experts was convened to develop state-of-the-art recommendations for its management.
Bronchial artery embolization (BAE) has been accepted as the most effective minimally invasive therapy alternative to surgery for massive and recurrent hemoptysis (1,2). However, because BAE does not address the underlying disease, recurrence of hemoptysis is common and requires frequent repeat embolization (3). Although advances in embolic materials and embolization techniques have led to technical improvements, there has been no substantial change in the overall recurrence rates since the 1970s (4,5). Therefore, there is no consensus on which embolic material is best; as of now, absorbable gelatin sponge particles or polyvinyl alcohol (PVA) particles are most widely used because they are inexpensive, easy to handle, and can be controlled with regard to embolic size (1,5,6).
Despite recent improvements in surveillance programs, some hepatocellular carcinomas (HCCs) are diagnosed at an advanced stage, with vascular invasion and distant metastasis corresponding to Barcelona Clinic Liver Cancer (BCLC) stage C, for which systemic therapy with sorafenib (Bayer Healthcare, Leverkusen, Germany) is widely accepted as the current standard of care (1–3). Although sorafenib has demonstrated clear survival benefits in both Western and Asia-Pacific patients with advanced HCC, it displays only modest clinical efficacy as a single therapy in this poorly controllable disease; hence, there is an urgent need for new treatment strategies (4,5).
A 70-year-old asymptomatic woman with a history of hypertension visited her primary care physician for a checkup. The findings of a physical examination performed at this time were unremarkable. Laboratory results were remarkable for an increased creatinine level of 1.62 mg/dL (143.21 μmol/L), which was up from her baseline level of 1.02 mg/dL (90.17 μmol/L). Renal ultrasonography (US) and subsequent computed tomography (CT) of the chest, abdomen, and pelvis were performed.
The approval of the new certificate in interventional radiology (IR) and diagnostic radiology (DR) by the American Board of Medical Specialties (ABMS) was the culmination of more than 7 years of focused work and was just one incremental step in more than 2 decades of change in IR training (1). The approval was a notable event for two reasons: The basic training schematic in IR was changed from a 1-4-1 pattern (years of internship-years of DR-years of IR) to a 1-3-2 pattern, and IR was recognized as a primary specialty of the American Board of Radiology (ABR). Of critical importance and by careful design, IR remains a part of radiology, interventional radiologists remain radiologists, and the new programs will reside within radiology departments and report to DR chairs. The new certificate signifies competence in both DR and IR. Nevertheless, this is a big change for radiology and engenders much passionate discussion among stakeholders (2).
In September of 2012, the American Board of Medical Specialties (ABMS) approved a new field of residency training, the interventional radiology (IR) residency (1). The Accreditation Council of Graduate Medical Education (ACGME) added its approval in June of 2013. The result is a new pathway to becoming an interventional radiologist (2).

There is increasing evidence supporting endovascular intervention in patients with critical limb ischemia (CLI) and infrapopliteal artery occlusion where in-line flow to the foot can be reestablished. Patients with CLI due to infrapopliteal arterial occlusive disease are a high-risk group in which the current reported amputation and mortality rates at 1 year are 25% and 20 to 25%, respectively.[1] [2] Treatment of infrapopliteal arterial disease is vital to prevent amputation, relieve ischemic pain, heal lower extremity wounds, and prevent gangrene.
Incidence and mortality trends attributed to kidney cancer exhibit marked regional variability, likely related to demographic, environmental, and genetic factors. Efforts to identify reversible factors, which lead to the development of renal cell carcinoma (RCC), have led not only to a greater understanding of the etiology of RCC but also the genetic and histologic characteristics of renal tumors. This article describes this evolution by discussing contemporary RCC incidence and mortality data, the risk factors for development of RCC, the histologic features, and anatomic and integrated staging systems that guide treatment.
Interventional radiology (IR) has seen an increase in the numbers of patients referred for urinary diversion in patients with ureteral leaks. This increase has corresponded to the increasing use of complicated surgical procedures for lower urinary tract tumors
Women with histologically proven concordant benign breast disease are often followed closely after biopsy for a period of two years, and they are considered to be at high-risk for cancer development. Our goal was to evaluate the utility of short-term (six-month) imaging follow-up and determine the incidence of breast cancer development in this population.
