A thorough pre-procedural patient evaluation promotes patient comfort and safety prior to any transradial access case in interventional radiology. Effective communication by health staff is key for guiding a patient’s expectations about an upcoming procedure and for improving overall patient satisfaction. The process of informed consent provides patients with autonomy over their health and with further understanding about the risks and benefits that are specific to procedures utilizing a radial access approach. Patients can be informed that transradial access has a reduced rate of complications when compared to transfemoral access. It is important to screen a patient’s medical history, physical exam, and medication reconciliation for particular details that may influence the appropriateness criteria for a radial access approach.

Several treatment options exist for acute intra-abdominal arterial thromboembolic events, including systemic thrombolytics, endovascular therapy, and less commonly surgery. A novel alternative treatment intervention for acute intra-abdominal arterial thrombus is the use of stent retriever (SR) devices, tools traditionally applied for treatment of acute vascular thrombosis in stroke patients. This brief report presents two cases of acute intra-abdominal arterial thrombosis successfully managed by deployment of SRs. Furthermore, it details the history, device mechanism, and design of SRs and describes cases in literature involving effective extracranial SR application.

Spontaneous dissection of abdominal aortic branches is rare. Prior reports discuss incidents of isolated renal artery dissections and isolated splanchnic artery dissections; however, these types of dissections almost never occur simultaneously. Based on literature review, only one other case report has described spontaneous dissections of multiple visceral arteries. This brief report presents the successful endovascular treatment of a previously healthy man with spontaneous dissection of the proximal celiac artery and bilateral renal arteries. Due to the patient's acute presentation and renal injury, stenting of bilateral renal arteries was undertaken with successful medical outcomes on postprocedural follow up.

Subarachnoid hemorrhage is a medical emergency. Berry aneurysm rupture is the second most common cause following trauma. Diagnosis is often challenging. Neurogenic heart syndrome often complicates subarachnoid hemorrhage. A concomitant pheochromocytoma can be deadly causing sudden cardiac arrhythmia. Here, we describe a case of subarachnoid hemorrhage with concomitant incidental pheochromocytoma in a relatively young female who died suddenly, diagnosed during autopsy. A 57-year-old Hispanic woman with past medical history of asthma, prediabetes, and uncontrolled hypertension collapsed unexpectedly. She initially had ventricular tachycardia, followed by pulseless electrical activity and finally asystole without response to resuscitation. In the emergency department she was on epinephrine, calcium, naloxone, and tPA with suspected thrombotic stroke. Despite measures, she was pronounced dead. Autopsy revealed subarachnoid hemorrhage due to a ruptured berry aneurysm. Additionally, pheochromocytoma was detected in the right adrenal gland. Subarachnoid hemorrhage has a grave prognosis by itself. This case describes the uncommon detection of pheochromocytoma in the setting of subarachnoid hemorrhage.
