A 72-year-old woman with a history of malignant lymphoma was referred to our hospital for the treatment of a bronchial artery aneurysm. Computed tomography (CT) scan showed a round, 30 mm-diameter fusiform aneurysm with two tortuous inflow arteries. We deployed thoracic stent grafting to cover the orifice of the two inflow arteries without transcatheter bronchial arterial embolization. Postoperative CT scan revealed complete thrombosis of the aneurysm. Although further follow-up is mandatory, this may be considered a viable treatment option in cases wherein the bronchial artery aneurysm is anatomically difficult to treat...

PURPOSE: Transcatheter arterial embolization (TAE) has been widely used in treating non-curative hepatocellular carcinoma (HCC). However, it is noticed that TAE may cause invasion of some cancer cells into circulation, resulting in distal metastasis and poor therapeutic outcome. Here, we aimed to reduce the side effects of TAE using the inhibitors for epidermal growth factor receptor (EGFR). METHODS: Transient hepatic artery ligation (HAL) was used as a mouse model for TAE...

OBJECTIVE: To report our experience on the value of transcatheter arterial embolization (TAE) or transcatheter arterial chemoembolization (TACE) for the uterus-preserving management of retained placenta accreta with marked vascularity after abortion or delivery. STUDY DESIGN: Thirty-eight consecutive women with retained placenta accreta were retrospectively analyzed over a 5-year period. When elevated levels of serum β-hCG (> 25 mIU/mL) were detected, TACE with dactinomycin was chosen for devascularization along with cytotoxic effects on active trophoblasts; in contrast, if the serum β-hCG level was low (≤ 25 mIU/mL), TAE was chosen...

A pulmonary arteriovenous malformation (PAVM) is a direct connection between the pulmonary arteries and veins for which metallic coil transcatheter embolization is the standard of care. Detecting recanalization after PAVM treatment is crucial, but direct visualization with computed tomography or magnetic resonance imaging (MRI) is generally difficult. Here, we report a case of a recanalized PAVM that was directly detected with ultra-short echo time MRI. The detection of these signals in the coils was confirmed in a phantom study...

Limited clinical evidence demonstrates the effectiveness of direct retroperitoneal pelvic packing for hemorrhage control in pelvic fractures due to the difficulty in measuring pressure on the pelvic walls within the pelvic cavity after retroperitoneal pelvic packing. Using a cadaver model, the authors aimed to assess whether retroperitoneal pelvic packing generates pressure that exceeds the venous return and arterial pressure in the pelvis. The pressure on the pelvic wall was measured in 5 fresh Japanese cadavers...

Ruptured pheochromocytoma is a rare disease. Its mortality rate is up to 31%-50%. Proper management of ruptured pheochromocytoma remains unclear. A 44-year-old male patient visited our Emergency Department and presented with abrupt onset of left flank pain. His blood pressure was 190/140 mmHg with purse rate of 130 beats/min. CT scan showed 8.1 × 5.6-cm-sized heterogeneously mass with rupture on the left retroperitoneal space and active bleeding. His symptom of abdominal pain was aggravated. Follow-up laboratory analysis revealed elevated WBC count and decreased hemoglobin 2 hours after admission...

The kidney is the third most common abdominal organ to be injured in trauma, following the spleen and liver, respectively. The most commonly used classification scheme is the American Association for the Surgery of Trauma (AAST) classification of blunt renal injuries, which grades renal injury according to the size of laceration and its proximity to the renal hilum. Arteriovenous fistula and pseudoaneurysm are the most common iatrogenic biopsy-related or surgery-related vascular injuries in native kidneys. The approach to renal artery injuries has changed over time from more aggressive intervention to more conservative observational or endovascular management, including selective transcatheter arterial embolization (TAE) and the placement of stents/stent grafts...

PURPOSE: CT during hepatic arteriography (CTHA) of cone-beam computed tomography (CBCT) provides valid information in performing transcatheter arterial chemo-embolization (TACE). The usefulness of CTHA with the diluted contrast medium has been reported in some medical conferences. However, the operation becomes somehow complicated for the medical institutions that have angiography injectors with a single head. In this study, we aimed to investigate the clinical equivalence of low-rate injection method and diluted injection method...

BACKGROUND: Visceral artery aneurysms at the origin of the gastric and gastroepiploic artery are uncommon. Raptured visceral aneurysms cause high mortality and require urgent and adequate intervention and treatment. PRESENTATION OF CASE: A 65-year-old woman was transferred to the emergency department with sudden abdominal and back pain. Radiographically, we diagnosed intra-abdominal bleeding due to a ruptured aneurysm of the right gastric artery. Although her vital signs were relatively stable, transcatheter arterial embolization (TAE) could not be performed due to thrombotic occlusion of her abdominal aorta, and bilateral axillary arteries...

Pulmonary arteriovenous malformation, which is defined as the presence of an ab-normal connection between the pulmonary artery and pulmonary vein, is rarely seen. Although it generally presents as a congenital condition, it may be accompanied by hereditary hemorrhagic telangiectasia. Clinical signs vary according to the amount of shunt in proportion to the number and size of the fistulae. Patients may present with cyanosis and respiratory trouble. If the disease remains untreated, it may result in cardiac failure and ineffective endocarditis, thereby leading to the rupture of the an-eurysmal fistula...

We herein report an uncommon case of a life-threatening retroperitoneal hematoma after a bone marrow biopsy. Two hours after iliac crest bone harvesting, the patient experienced syncope and severe hypotension. Urgent contrast-enhanced computed tomography demonstrated extravasation from the superior gluteal artery. Transcatheter coil embolization was performed successfully, without complications. Life-threatening complications caused by retroperitoneal bleeding after bone marrow biopsy are very rare. There are few reports on the use of endovascular treatment in the management of life-threatening hemorrhagic complications after bone marrow biopsy...

Background: Currently, there are few strategies for improving the quality of life (QOL) in patients with autosomal dominant polycystic kidney disease (ADPKD) and massive kidneys. Renal transcatheter arterial embolization (TAE) reduces kidney volume, but its impact on QOL in ADPKD patients on hemodialysis is unknown. This study investigated the influence of renal TAE on QOL in ADPKD patients with massive kidneys receiving hemodialysis. Methods: This prospective observational study enrolled 188 ADPKD patients on hemodialysis (92 men and 96 women; mean age 56...

BACKGROUND: The reversed Potts shunt improves right ventricular (RV) function in patients with suprasystemic pulmonary arterial hypertension (PAH). The proximity of the left pulmonary artery (LPA) to the descending aorta (DAo) permits the creation of a transcatheter connection. We sought to assess the safety, feasibility, and hemodynamic efficacy of the transcatheter Potts shunt (TPS) in children. METHODS: The TPS procedure was performed using radiofrequency energy for vessel perforation and deployment of a covered stent to connect the DAo and LPA...
