To evaluate the safety and efficacy of two different methods of proximal cystic artery embolization in patients undergoing yttrium-90 radioembolization. Materials and Methods Forty-six patients had cystic artery embolization performed immediately before yttrium- 90 radioembolization, either by using Gelfoam pledgets (n = 35) or coils (n = 11). Clinical symptomatology during the admission and angiographic findings at 1-month follow-up were retrospectively reviewed. Rates of collateralization or recanalization of the cystic artery were compared, as well as the frequency of postprocedural abdominal pain and need for cholecystectomy.

Stent graft has resulted in major advances in the treatment of trauma patients with blunt traumatic aortic injury (TAI) and has become the preferred method of treatment at many trauma centers. In this review, we provide an overview of the place of stent grafts for the management of this disease. As a whole, TEVAR repair of TAIs offers a survival advantage and reduction in major morbidity, including paraplegia, compared with open surgery. However, endovascular procedures in trauma require a sophisticated multidisciplinary and experienced team approach. More research and development of TAI-specific endograft devices is needed and large, multicenter studies will help to clarify the role of TEVAR compared with open repair of TAI.

Suboptimal blood pressure control is a leading cause of death globally and is responsible for 7 million deaths annually.1 It is estimated that one in four adults worldwide are hypertensive, equating to nearly 1 billion people—a number that is expected to grow to nearly 1.5 billion by 2025. Current therapeutic strategies center on lifestyle changes and pharmacologic interventions; however, the rates of blood pressure control and therapeutic efforts to reduce the rate of progression of hypertensive end-organ damage (resulting in myocardial infarction, stroke, and renal dysfunction) remain a neglected priority.

Despite significant improvements in diagnosis and pharmacotherapy, arterial hypertension remains a global health problem. The development of new antihypertensive drugs has not provided a satisfactory benefit. Resistant hypertension (defined as the failure to reach goal blood pressure [BP] in patients adhering to full doses of an appropriate three-drug regimen including a diuretic) is still diagnosed in approximately 13% of patients.1,2 This subgroup of patients has an increased risk of cardiovascular and renal events and requires additional therapy options. One of these options may be the renal denervation (RDN) method, which is based on the attenuation of a great contributor to the pathogenesis of arterial hypertension—the sympathetic nervous system.
Percutaneous vertebroplasty is a minimally invasive surgical technique for the treatment of spinal damage and pathological compression fractures. Iodine-125 (I-125) particles can inhibit the uncontrolled proliferation of tumor cells to achieve anti-tumor effects. We report treating a spinal cord compression and T5 metastatic lung cancer patient through percutaneous vertebroplasty and I-125 seed implantation. Three years of follow-up demonstrated that our surgical plan achieved a satisfactory clinical outcome with good postsurgical recovery of spinal column function and relieved the symptoms of spinal cord compression.

Interventional radiology (IR) is an invasive speciality with the potential for complications as with other invasive specialities. The World Health Organization (WHO) produced a surgical safety checklist to decrease the morbidity and mortality associated with surgery. The Cardiovascular and Interventional Society of Europe (CIRSE) set up a task force to produce a checklist for IR. Use of the checklist will, we hope, reduce the incidence of complications after IR procedures. It has been modified from the WHO surgical safety checklist and the RAD PASS from Holland.
