Safety and efficacy of pelvic arterial embolization for primary postpartum hemorrhage in hemodynamically stable and hemodynamically unstable patients: Is it "time" for a paradigm change?

Background: Pelvic artery embolization (PAE) is an effective and safe technique for treating postpartum hemorrhage (PPH) with hemodynamic stability. However, its use in hemodynamically unstable patients remains controversial.

Purpose: To determine the safety and efficacy of pelvic arterial embolization (PAE) according to the hemodynamic state of primary postpartum hemorrhage (PPH) patients.

Varying Outcomes among Patients with Large Angiomyolipomas according to the Treatment Method.

Purpose: This study aimed to evaluate the outcomes of large angiomyolipoma (AML) treatment by selective arterial embolization (SAE) versus nephron-sparing surgery (NSS) using a robotic surgical system.

Materials And Methods: Between January 2011 and June 2018, we retrospectively reviewed 25 patients who underwent robot-assisted partial nephrectomy (RAPN) or SAE for large AMLs. Ten patients underwent RAPN, and 15 underwent SAE.

The Hemoptysis and the Subclavian Artery Pseudoaneurysm due to a Fishbone Injury: A Case Report.

Ingestion of a foreign body is a common cause of esophageal injury, but hemoptysis is a rare manifestation of the esophageal penetration by a swallowed foreign body. The swallowing of a fishbone is hard to diagnose and the definite diagnosis is usually made during surgery. We describe the case of a 50-year-old man with direct injury to the lung parenchyma, the azygos vein, and the subclavian artery pseudoaneurysm due to a fishbone penetration from the upper esophagus into the lung.

Delayed, life-threatening hemorrhage after self-expandable metallic biliary stent placement: clinical manifestations and endovascular treatment.

Background: Life-threatening, delayed hemorrhage after self-expandable metallic stent (SEMS) insertion for malignant biliary obstruction is very rare. Clinical manifestations, radiologic characteristics, treatment, and prognosis of this complication are not well-known.

Purpose: To present the clinical manifestations, radiologic findings, and endovascular treatment of life-threatening, delayed hemorrhage secondary to SEMS placement.

Can the 1.8 mm transnasal biopsy forceps instead of standard 2.2 mm alter rapid urease test and histological diagnosis?

Background And Aim: Biopsy specimens are taken during transnasal esophagogastroduodenoscopy with 1.8 mm forceps. The aims of this study were to compare the concordance of the Campylobacter-like organism (CLO) test and histological diagnoses between biopsies taken with 1.

Ultrasonographic analysis of subcutaneous angiolipoma.

Objective: To describe and analyze the ultrasonographic appearance of subcutaneous angiolipoma in pathology-proven cases.

Materials And Methods: We retrospectively searched the January 2004 to May 2011 surgical pathology database for cases of pathology-proven angiolipoma. The ultrasonographic findings were analyzed for angiolipoma size, shape, margin, echo texture, echogenicity, acoustic enhancement, calcifications, and color Doppler flow.

Classification of persistent primitive trigeminal artery (PPTA): a reconsideration based on MRA.

Background: Persistent primitive trigeminal artery (PPTA) is the most common permanent carotid-basilar anastomosis. Magnetic resonance angiography (MRA) has become the primary non-invasive imaging technique for evaluation of cerebral vascular anatomy and can provide detailed 3D imaging of intracranial vessels.

Purpose: To evaluate the usefulness of MRA for the detection of PPTA and to re-classify its variations based on the embryologic types of PcomA and its relationship with the basilar artery and its branches.

Intra-arterial adjuvant tirofiban after unsuccessful intra-arterial thrombolysis of acute ischemic stroke: preliminary experience in 16 patients.

Introduction: Intra-arterial (IA) thrombolysis with plasminogen activator is well-known, but the use of IA tirofiban as an adjuvant for IA thrombolysis is not well-known. We investigated the feasibility of IA tirofiban as an adjuvant after unsuccessful IA recanalization with urokinase (UK) for acute ischemic stroke.

Methods: We retrospectively analyzed all 16 consecutive patients (11 men and five women; mean age, 61.

Acute kidney injury after transarterial chemoembolization for hepatocellular carcinoma: a retrospective analysis.

Background: Transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) may result in acute kidney injury (AKI) like other angiographic interventions.

Methods: To investigate the incidence, risk factor and outcomes of AKI after TACE, defined by Acute Kidney Injury Network (AKIN) criteria, we retrospectively analyzed 442 TACE treatment sessions in 236 HCC patients.

Results: The incidence of AKI in the first 48 h after TACE was 9.

A new model of tracheal stenosis in dogs using combined bronchoscopic electrocautery and ethanol injection.

Purpose: To establish a new animal model of tracheal stenosis in dogs that involves combined bronchoscopic electrocautery and ethanol injection.

Materials And Methods: Ten mongrel dogs were included in the study. With flexible bronchoscopic and fluoroscopic guidance, a combination of electrocautery (30 W) and ethanol injection (total volume 2 mL) was circumferentially applied to the trachea at the third thoracic vertebra level.

[Hemobilia from pancreatic arteriovenous malformation: successful treatment with transportal coil embolization of draining veins].

Pancreatic arteriovenous malformations (AVM) are extremely rare diseases frequently complicated by gastrointestinal hemorrhage. While surgical resection of affected lesion is preferred for the treatment of pancreatic AVM, angiographic intervention can be used as an alternative treatment, especially in surgically high-risk patients. We experienced a patient with pancreatic AVM manifested by hemobilia and biliary sepsis.

Renal artery embolization of perirenal hematoma in hemorrhagic fever with renal syndrome: a case report.

Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease characterized by fever, hemorrhage and renal failure. Among the various hemorrhagic complications of HFRS, spontaneous rupture of the kidney and perirenal hematoma are very rare findings. We report here on a case of HFRS complicated by massive perirenal hematoma, and this was treated with transcatheter arterial embolization.

Suppressive effect of Zedoariae rhizoma on pulmonary metastasis of B16 melanoma cells.

The inhibitory effect of Curcuma zedoaria Roscoe (WE-CZ) on experimental pulmonary metastasis of B16 melanoma cells was investigated. The intake of WE-CZ at doses of 250 and 500 mg/kg for 6 weeks from 2 weeks before tumor inoculation significantly reduced the number of metastatic surface nodules in the lung, resulting in an extended life span. When the duration of WE-CZ intake was examined, survival time was not affected by pre-intake before B16 melanoma cell inoculation and was slightly extended by post-intake after B16 melanoma cell inoculation, although the life span was prolonged by intake throughout the experiment.

Operator-dependent techniques for graded compression sonography to detect the appendix and diagnose acute appendicitis.

Objective: The objective of our prospective study was to evaluate the value of various operator-dependent techniques that allow graded compression sonography to detect normal or abnormal vermiform appendix.

Subjects And Methods: A total of 877 subjects were included in this study. This sample population consisted of two groups: 202 control subjects and 675 patients who were suspected of having acute appendicitis.

Synovial sarcoma of the head and neck: a case of predominantly cystic mass.

We report a case of predominantly cystic synovial sarcoma partly adherent to the hyoid bone in the submental area. The mass demonstrated posterior acoustic enhancement at sonography and a complex cystic mass with mural nodules and solid septa at CT.

Graded compression sonography with adjuvant use of a posterior manual compression technique in the sonographic diagnosis of acute appendicitis.

Objective: We evaluated the usefulness of graded compression sonography with the adjuvant use of a posterior manual compression technique for detection of the vermiform appendix and the diagnosis of acute appendicitis.

Subjects And Methods: Five hundred seventy consecutive patients referred for suspected acute appendicitis were prospectively examined by original, graded compression sonography with a 5- or a 7.5-MHz linear transducer.
