RATIONALE: Isolated dissection of the celiac artery (IDCA) is one of isolated visceral artery dissection, which can occur alone, and can also be complicated with superior mesenteric artery dissection and splenic artery pseudoaneurysm. This disease is very rare in clinic. The exact pathogenesis of IDCA remains unknown. At present, no consensus has yet been reached on the best treatment strategy for this rare disease. In the present study, the clinical data of one IDCA patient diagnosed and treated in our hospital was retrospectively analyzed, and related literatures were reviewed, in order to improve the understanding of the disease...

Aortic root aneurysm is the most common cardiovascular manifestation requiring surgical intervention in patients with Marfan syndrome (MFS), a heritable thoracic aortic disease. Elective replacement of the aortic root is the treatment of choice for patients with aneurysmal complications of the aortic root and ascending aorta. There are two basic approaches to aortic root replacement: valve-sparing (VS) and valve-replacing (VR) techniques. After successful aortic root replacement surgery, several patients with MFS may develop a late complication related to their aortic disease process, such as developing a pseudoaneurysm of the coronary artery reattachment buttons, aneurysmal expansion, or aortic dissection in the remaining native aorta...

Enlarging LV pseudoaneurysms are a rare complication (especially after surgical revascularization) and require tailored surgical decision-making and techniques for repair. We present a challenging case of a rapidly enlarging LV pseudoaneurysm four weeks after coronary bypass. The repair was approached via left thoracotomy utilizing circulatory arrest with selective antegrade cerebral perfusion.

OBJECTIVE: Rupture of uterine artery pseudoaneurysm (UAP) is a life-threatening event after childbirth. Hysterectomy or uterine arterial embolization was often needed for hemostasis. However, such procedures may cause severe morbidities for these women. To estimate the efficacy of uterine balloon tamponade (UBT) for controlling ruptured UAP bleeding, a retrospective analysis in a single teaching hospital was performed. MATERIALS AND METHODS: We reviewed the medical record of Juntendo University Hospital in 2015...

BACKGROUND: The pseudoaneurysms of sinus of Valsalva is an uncommon and serious complication of an infection, trauma, or after cardiac surgery or procedure. Pseudoaneurysms of sinus of Valsalva from left is rare. We describe a case of pseudoaneurysm of the left coronary sinus of Valsalva invaded into the left ventricle (LV) diagnosed by transthoracic echocardiography (TTE), transesophageal ecoccardiography (TEE), and multiple detector computed tomography (MDCT). CASE PRESENTATION: A 44-year-old male patient had New York Heart Association (NYHA) class II / III dyspnea during 4 months...

A chronically persistent left atrial pseudoaneurysm is a rare complication of valvular surgery, trauma, myocardial infarction and endocaritis but this is the first known description of a chronic pseudoaneurysm as a complication of coronary rupture during percutaneous coronary intervention (PCI). We report computed tomography images depicting this in the case of elective PCI in an 81-year-old gentleman for limiting angina.

Splenic artery pseudoaneurysms (PSA) are rare entities and far less common than true aneurysms of the splenic artery. The most common etiology is pancreatitis, recurrent either in the setting of chronic pancreatitis or as an episode of acute pancreatitis. Less common causes include trauma, peptic ulcer disease, or iatrogenic causes. Almost all of the trauma-related case reports have been due to blunt trauma. We believe this to be the first reported case of a splenic artery PSA presenting with massive hematemesis at a significant time frame after penetrating trauma...

BACKGROUND: Although research on pediatric intracranial aneurysms is well documented, studies of pediatric intracranial distal arterial aneurysms (PIDAAs) remain scarce. METHODS: All pediatric patients (≤ 18 years) with intracranial aneurysms located distally to the M2 segment of the middle cerebral artery (MCA), A2 segment of the anterior cerebral artery, P2 segment of the posterior cerebral artery, and other cerebral arteries distal to the main branch who were treated at our center between January 2012 and April 2017 were retrospectively reviewed...

Hemorrhagic complications are the most common major complications that occur after radiofrequency ablation, but hematemesis as a complication after radiofrequency ablation for hepatic tumor has not been mentioned before. A hepatogastric fistula as a delayed complication is also rare. We present the case of a 77-year-old man with severe hematemesis that occurred 2 months after radiofrequency ablation of a liver metastasis of gastric cancer. A ruptured hepatic artery pseudoaneurysm and a hepatogastric fistula were confirmed through serial imaging examinations...

PURPOSE: To investigate the endovascular treatment (stenting with or without coiling) of cervical and intracranial lesions associated with internal carotid artery (ICA) redundancy. MATERIALS AND METHODS: Nine patients harboring twelve lesions of dissections, pseudoaneurysms and aneurysms in the presence of ICA redundancy were treated using stent deployment with or without coiling. There were eight females and one male patient with an age range of 31-89 years (mean 55)...

Giant cavernous aneurysms of the internal carotid artery (ICA) are challenging lesions associated with high surgical morbidity. Prior to the past several years, these were treated by surgical reconstruction, proximal ligation, or stent-assisted coiling techniques. Flow diversion has become the standard of care for these lesions, providing a high rate of obliteration with a much better safety profile. However, flow diverters rely upon a navigable vasculature and, usually, a tri-axial support system. Cases in which such access is difficult require unique approaches to combine the strengths of both surgical and endovascular therapy...

Pulmonary artery pseudoaneurysm (PAPA), an uncommon complication of pyogenic bacterial and fungal infections and related septic emboli, is associated with high mortality. The pulmonary artery (PA) lacks an adventitial wall; therefore, repeated endovascular seeding of the PA with septic emboli creates saccular dilations that are more likely to rupture than systemic arterial aneurysms. The most common clinical presentation of PAPA is massive hemoptysis and resultant worsening hypoxemia. Computed tomography angiography is the preferred diagnostic modality for PAPA; typical imaging patterns include focal outpouchings of contrast adjacent to a branch of the PA following the same contrast density as the PA in all phases of the study...
