A case of an unruptured hepatic aneurysm on the common hepatic artery at the junction of the gastroduodenal and proper hepatic arteries treated with transcatheter arterial embolization.

Hepatic aneurysms are rare, but can prove fatal once they rupture. Transcatheter arterial embolization (TAE) is performed as a prophylactic treatment. The position of the aneurysm determines the degree of difficulty of TAE. Maintaining blood flow to the liver can become difficult, particularly when the aneurysm is at an arterial junction. The patient was a 72-year-old man diagnosed with a hepatic aneurysm. The aneurysm was situated on the common hepatic artery at the junction of the gastroduodenal and proper hepatic arteries. TAE was performed with framing, followed by coil embolization. Blood flow to the liver was maintained via the gastroduodenal artery. Appropriate framing is important for safe and efficient TAE.

The role of advanced practice nurses in improving healthcare outcomes for patients with chronic kidney disease: A scoping review protocol.

INTRODUCTION: The number of patients with chronic kidney disease is increasing worldwide; previous studies have suggested that advanced practice nurses, including nurse practitioners and clinical nurse specialists, with expert practice skills can provide high-quality care and solve complex healthcare problems. In general, nurse practitioners are generalist nurses who work as autonomous clinicians with whole personal care. Clinical nurse specialists, in contrast, are nurses with advanced nursing knowledge and skills for individuals or specific populations. Their roles are independent and different; however, similarities exist in their role in potentially improving healthcare outcomes. Although two previous studies described the role of nephrology nurse practitioners, they were systematic reviews, and their outcomes were limited. To clarify the overall aspect of advanced practice nurses' role, it is necessary to extract the studies illustrating advanced practice nurses' practices for patients with chronic kidney disease. OBJECTIVE: This study aims to map the literature describing the role of advanced practice nurses in improving healthcare outcomes for patients with chronic kidney disease. MATERIALS AND METHODS: This scoping review will be conducted using the Joanna Briggs Institute methodology for scoping review. Online databases will be searched across MEDLINE (PubMed), CINAHL (EBSCOhost), Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and Web of Science. Only studies published in English will be included, and no date limit will be set. Chronic kidney disease, renal replacement therapy, and advanced practice nurses as keywords and related search terms will be used. Two independent reviewers will screen the title and abstract/full-text; in case of discrepancy, a third reviewer will make the final decision. The results will be extracted and presented following the review question concerning the study characteristics, patients' characteristics, condition of chronic kidney disease, and role of advanced practice nurses.

[Case of ANCA associated vasculitis induced by interferon therapy for HCV infection].

A 50-year-old man with chronic HCV infection had been received the injections of 12MU of Consensus-Interferon (C-IFN) three times a week in a previous hospital. Six months later, C-IFN therapy was terminated because of fever and massive ascites. Diuretics and antibiotics had not been effective against these symptoms. In the meantime, skin symptoms of purpura and giant ulcers in the extremities developed, and he was transferred to our hospital. Because skin biopsy revealed vasculitis and serum MPO-ANCA was positive, the diagnosis of ANCA associated vasculitis was made. Methylpredonizoron pulse therapy improved skin symptoms and massive ascites, and the skin ulcers eventually disappeared. ANCA is suggested to be responsible for this rare complication.

Drug-induced liver injury with serious multiform exudative erythema following the use of an over-the-counter medication containing ibuprofen.

A 36-year-old Japanese woman took over-the-counter (OTC) medication for headaches for 20 days. Subsequently, five days after discontinuing the medication, a skin rash developed over the patient's upper and lower limbs and face, in addition to a fever, brown urine and serious liver dysfunction. Drug lymphocyte stimulation tests implicated ibuprofen, a main component of the OTC drugs, which has the potential to induce this pathology, and a diagnosis of drug-induced liver injury with multiform exudative erythema was made. The patient's symptoms and liver function tests returned to normal following treatment with systemic steroids.

Clear visualization of extravasation on angiography using carbon dioxide in a case of hepatocellular carcinoma rupture with unclear visualization using iodine contrast agent.

A 62-year-old woman with hepatocellular carcinoma (HCC) and asthma presented with acute abdominal pain and a decreased hemoglobin level. Peritoneal fluid was detected around the lesion, and rupture was suspected based on the findings of computed tomography. Extravasation of the HCC tumor was not detected on angiography with iodine contrast agent; however, such extravasation was clearly observed on angiography with carbon dioxide (CO2). CO2 angiography is sometimes utilized in patients with arterial bleeding. This modality be more effective and safe than angiography with iodine contrast agent for assessing potential ruptured HCC lesions.

Acute aortic dissection with new massive cerebral infarction - a successful repair with ligature of the right common carotid artery.

It remains unclear whether or not the infarcted brain caused by aortic dissection should be reperfused when an emergency operation is needed for aortic arch dissection. A 64-year-old woman presented with severe back pain and syncope with a sudden left hemiplegia. CT scan demonstrated an aortic dissection of the entire aorta, obstruction of the right common carotid artery by extended aortic dissection, cerebral infarction of the right middle cerebral artery territory, brain edema and pericardial effusion. Though she was unable to communicate with us, she underwent an emergent aortic arch replacement and ligature of the right common carotid artery nine hours after the onset of stroke, when massive cerebral infarction was established. She survived the operation and regained full consciousness. When brain infarction was established by extended aortic dissection in emergent aortic surgery, concomitant ligature of the responsible artery to the brain infarction may be allowed for avoiding cerebral damage leading to brain death.

Lateral supracerebellar transtentorial approach for petroclival meningiomas: operative technique and outcome.

OBJECT: The retrosigmoid intradural suprameatal approach with the patient in a semisitting position is an effective alternative to transpetrosal approaches for the treatment of petroclival meningiomas. The authors have made a simple modification to the retrosigmoid intradural suprameatal approach by using the lateral oblique position and preferentially dividing the tentorium with limited drilling of the suprameatal bone, which is termed the "lateral supracerebellar transtentorial approach." METHODS: Twenty-six patients with petroclival meningiomas surgically treated via the lateral supracerebellar transtentorial approach were analyzed. All tumors had most of their bulk in the posterior fossa with some degree of extension into the middle fossa and/or Meckel cave. The patient is placed in the lateral oblique position, and a standard retrosigmoid craniotomy is performed. The tentorium medial to the trigeminal nerve is incised toward the free edge, which improves exposure to the petroclival region without extensive resection of the suprameatal petrous bone. RESULTS: Gross-total resection was achieved in 11 patients (42%). Ten patients (38%) underwent subtotal resection, and 5 patients (19%) underwent partial resection. There was no incidence of operative death, and the postoperative permanent morbidity rate was 15%. All patients except one did well postoperatively and were independent at the time of their last follow-up examinations. CONCLUSIONS: The lateral supracerebellar transtentorial approach provides the simplest and safest access to the petroclival region. It offers an advantageous approach to petroclival meningiomas exclusively located in the posterior fossa with minimal extension into the Meckel cave and middle fossa.
