Computed tomography demonstrated a giant saphenous vein graft aneurysm that compressed the right atrium of a 72-year-old woman 20 years after undergoing coronary artery bypass grafting. Angiography revealed contrast medium leakage in the mid-portion of the graft aneurysm. Aneurysmectomy was performed without repeat grafting. Postoperative myocardial scintigraphy demonstrated no significant ...

Idiopathic pulmonary artery aneurysm rupture was diagnosed in a 79-year-old man who presented with a dry cough. He was considered unlikely to tolerate extensive pulmonary artery reconstruction or lung resection; hence, he was salvaged by timely ligation of the distal pulmonary artery at the origin of the aneurysm.

The splenic artery arising from the superior mesenteric artery is an uncommon anatomical variant. This aberrant origin may rarely be associated with an aneurysm. Previous cases have been managed with surgery and combined surgical/endovascular or endovascular techniques, with the latter involving occlusion of the aneurysm with coils. We report a ...

Closure of adult patent ductus arteriosus (PDA) is difficult for its variation. We report a case of open stent-grafting for a 67-year-old woman who had PDA and a concomitant distal aortic arch aneurysm. The pulmonary/systemic flow ratio was 1.88, and the pulmonary arterial pressure was 34/21(25). The operation was done ...

Hereditary Haemorrhagic Telangiectasia (HHT) is a genetic disorder responsible for cutaneous or mucosal telangiectasia and arteriovenous malformations (AVMs). The most frequent locations are lung and brain. In contrast, orbital AVMs are very rare. We describe a case of symptomatic orbital arteriovenous malformation due to spontaneous thrombosis. A 65-year-old woman was ...

Endovascular repair of isolated iliac artery aneurysms is an established safe and effective management option. Type II endoleak is a potential complication, but rarely results in significant morbidity or mortality. We report a case of a patient who presented with a ruptured internal iliac artery aneurysm secondary to a Type ...

We report on a 66-year-old woman with a posterior circulation stroke that occurred after bronchial artery embolization (BAE) due to post-tuberculous bronchiectasis. Stroke is a rare complication of BAE and is usually thought to be caused by inadvertent embolization via a bronchial artery-pulmonary vein shunt. However, the possibility of thromboembolic ...

Good status of pulmonary perfusion is essential for a successful outcome after the Fontan procedure. Increased pulmonary pressure and vascular resistance, small size of the pulmonary arteries, and significant branch stenoses reflect some of the main problems causing failing Fontan circulation. Here we report a child who underwent a staged ...

Abstract  Ruptured thoracic aortic tuberculous pseudoaneurysms as a complication of mycobacterium tuberculosis infection of the spine are rare. Conventional treatment of a ruptured tuberculous pseudoaneurysm involves surgery with graft interposition or patch repair. We report successful repair of a ruptured tuberculous pseudoaneurysm of the descending thoracic aorta by endovascular stent ...

Aneurysms of the anterior choroidal artery are uncommon and account for only 2-5% of all intracranial aneurysms. Distal anterior choroidal artery aneurysms are rare and the pathogenesis of this aneurysm may be different from typical proximal ones. We describe an unusual case of ruptured de novo distal anterior choroidal artery ...

Pulmonary atresia and ventricular septal defect (PA-VSD) was diagnosed in a 2-year-old castrated male Terrier mix. Transthoracic echocardiography identified a large ventricular septal defect, overriding aorta and severe right ventricular hypertrophy. A main pulmonary artery could not be identified, consistent with pulmonary atresia or persistent truncus arteriosus. Transesophageal echocardiography and ...

Obstruction to a prosthetic cardiac valve is a well-recognized complication of cardiac valve replacement. Malfunction of the mobile component of a prosthetic valve to open or close correctly may occur in consequence of intrinsic or extrinsic causes (thrombus, vegetation, entrapment of left ventricular myocardium, suture entanglement, and pannus formation) that ...

BACKGROUND: Krüppel-like zinc-finger transcription factor 5 (KLF5), known as BTEB2 and IKLF, has several biological functions that involve cell proliferation, development, and apoptosis. In human cerebral aneurysms, macrophage infiltration is profoundly associated with growth and rupture, but the role of KLF5 remains unclear. We examined the significance of KLF5 expression ...

Object Intrasellar aneurysms are rare lesions that often mimic pituitary tumors, potentially resulting in catastrophic outcomes if they are not appropriately recognized. The authors aimed to characterize the clinical and anatomical details of this poorly defined entity in the modern era of neuroimaging and open/endovascular neurosurgery. Methods A PubMed literature ...

Complications during cerebral aneurysm embolization continue to occur even at high volume experienced centers. Such situations are unexpected, complex and can have devastating consequences. Individual anecdotal experience offers limited guidance. This literature review of the two most serious neuroendovascular procedural complications-namely, aneurysm perforation and thromboemboli-aims to propose a role based ...

Inferior vena cava (IVC) filters are widely used to decrease the risk of pulmonary embolism in patients with contraindications to anticoagulation. Complications include local hematoma, access site deep venous thrombosis (DVT), filter migration and embolization, leg penetration through the IVC wall, IVC occlusion, and filter fracture with embolization. Other rare ...

OBJECTIVE: The role of hemodynamics in the growth of intracranial aneurysms is not completely clear. We present a hemodynamic study with two adjacent unruptured aneurysms arising from one parent artery but growing in different ways. This study aimed to investigate whether there were differences in hemodynamic characteristics between the two ...

Treatment of peripheral chronic total occlusion (CTO) is one of the most challenging lesion subsets in peripheral revascularization. Advanced wire technology, novel re-entry catheters and imaging techniques help in crossing such lesions. Subintimal dissection using blunt microdissection devices along with true lumen reentry techniques have added to the success rates ...

Long-term outcomes after endovascular aneurysm repair (EVAR) for inflammatory aneurysms are unknown. We present a young patient with new-onset back pain and failure to thrive 6 years after EVAR for an inflammatory abdominal aortic aneurysm (AAA). Endograft explanation was performed with a presumed diagnosis of infection. Pathology revealed intimal sarcoma ...

Endovascular stents are being commonly used to treat cerebral wide-necked aneurysms recently. The effect of a stent placed in the parent artery is not only to protect the parent artery from occlusion, due to extension of coils and thrombosis, but also to act as flow diverter to vary the haemodynamics ...

Pulmonary chondromas are very rare benign tumors. We report a case of huge solitary pulmonary chondroma in a 53-year-old woman without specific symptom. The lesion was detected by CT and Tc-99m methylene diphosphonate bone scintigraphy. The primary diagnosis after radiologic examination was pulmonary hamartoma. Then, surgical excision was performed, and ...

This is a case of a right coronary artery (RCA) diverticulum. We highlight the complications of distal embolization and recurrent myocardial infarctions (MI), and the successful closure with a covered stent. A 33-year-old Khat user experienced non-ST elevation MI (non-STEMI) 3 times over 2 years. His first cardiac catheterization showed ...
