A 33-year male with history of penetrating trauma to left upper chest in 2006, presented through Medical unit to Radiology Department with complain of hemoptysis. Chest X-ray showed a soft tissue lesion in left upper lobe with a linear metallic foreign body. Contrast enhanced CT scan of chest and later CTA was performed which showed a saccular aneurysm arising from mediastinal part of left common aortic artery surrounded by thrombosis with a cylindrical linear metallic foreign body. He was planned for endovascular repair with stenting which he could not afford due to financial constraints...

Aortoesophageal fistula is a rare but life-threatening cause of massive gastrointestinal bleeding. We reported a case of primary aortoesophageal fistula associated with thoracic aortic pseudoaneurysm. Esophagogastroduodenoscopy demonstrated a bulging erosive lesion coated with fibrin. The patient was therefore diagnosed as malignant esophageal mesenchymoma initially. An emergency contrast-enhanced computed tomography revealed an out-pouching saccular aneurysm protruding toward the esophagus at the level of T8-9...

Pneumococcal mycotic aneurysms are rare and associated with significant mortality and morbidity. Early intravenous antibiotic therapy and surgical intervention is the mainstay of treatment. Pneumococci frequently autolyze in blood cultures, making microbiological diagnosis challenging. We present the case of a man in his mid 70s with multiple thoracoabdominal mycotic aneurysms. Surgery was performed to a threatening saccular aortic arch aneurysm. Samples were sent for microbiological analysis and all were culture negative...

Abdominal aortic aneurysms (AAAs) and intracranial saccular aneurysms (IAs) are the most common types of aneurysms. This study was to investigate the common pathogenesis shared between these two kinds of aneurysms. We collected 12 IAs samples and 12 control arteries from the Beijing Tiantan Hospital and performed microarray analysis. In addition, we utilized the microarray datasets of IAs and AAAs from the Gene Expression Omnibus (GEO), in combination with our microarray results, to generate messenger RNA expression profiles for both AAAs and IAs in our study...

A 62-years-old female had undergone ascending aortic replacement with homograft for graft infection and mediastinitis after initial replacement of ascending aorta due to acute type A dissection. Ten years after homograft replacement, follow up computed tomography showed acute growing saccular aneurysm of the homograft without infectious symptoms. We urgently performed Bentall procedure and hemiarch replacement successfully. Pathological diagnosis was true aneurysm of the homograft. She was discharged from hospital without any complication and has been quite uneventful 7 years after surgery...

Hoarseness of voice due to Vocal Cord Palsy (VCP) resulting from aortic aneurysm is a rare entity. Hoarseness due to left Recurrent Laryngeal Nerve (RLN) paralysis caused by identifiable cardiovascular disease has been described as Ortner's syndrome or Cardiovocal syndrome. Very rarely, thoracic aortic aneurysm can cause Phrenic Nerve (PN) palsy causing hemidiaphragm paralysis. But, aortic aneurysm causing both RLN and PN palsy is an extremely rare occasion. Our literature review showed only three cases of combined RLN and PN palsy due to thoracic aortic aneurysm...

An 83-year-old male with multiple comorbidities presented with critical aortic stenosis and a saccular aortic arch aneurysm. Through a mini thoracotomy, a balloon expandable transcatheter aortic valve was delivered transapically. A thoracic stent graft was then delivered through the prosthetic valve and deployed in the arch, while a covered stent was deployed in the left common carotid artery. Three-year postoperative computed tomography showed a thrombosed arch aneurysm with decreased size. This case demonstrates the feasibility of using combined transapical transcatheter technologies to treat multicomponent disease in a high-risk patient during a single operation...

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is a rare disease consistent in vascular dysplasias affecting different organs. Liver involvement includes telangiectases, arteriovenous shunting, and ischemic cholangitis, and its prevalence ranges from 8% to 31%. Spontaneous pseudoaneurysms have never been reported associated to HHT. Several variations in the origin of the main hepatic artery (MHA) have been described in large radiological series and can be found in around 4% of general population...

The wall of a true aneurysm is composed of all histologic layers of the aorta. A false aneurysm represents a small, contained rupture of aorta followed by bulging of the corresponding area that is usually sustained by a fibrous peel. Aortic dissection is defined as a separation of the lamellae of the aortic wall. Herein, we describe an unusual clinical presentation of aortic dissection in a 37-year-old male patient that presented severe aortic regurgitation and unusual bulges with linear intimal fissures in ascending aorta underwent mechanical aortic valve replacement and interposition of tubular vascular graft in ascending aorta...

BACKGROUND AND PURPOSE: Among patients with vertebrobasilar dolichoectasia is a subset of patients with disease affecting the anterior circulation as well. We hypothesized that multivessel intracranial dolichoectasia may represent a distinct phenotype from single-territory vertebrobasilar dolichoectasia. The purpose of this study was to characterize clinical characteristics and angiographic features of this proposed distinct phenotype termed "diffuse intracranial dolichoectasia" and compare them with those in patients with isolated vertebrobasilar dolichoectasia...

We describe a very rare case of a 67-year-old man with multiple saccular aortic aneurysms throughout the entire aorta due to antineutrophil cytoplasmic antibody-associated vasculitis (AAV). The patient underwent staged aortic surgical procedures, including stent-graft insertion for a left iliac artery aneurysm, thoracic endovascular aortic repair for a descending aortic aneurysm, and total replacement of the ascending aorta and aortic arch with the use of high-dose steroids to control inflammation. The histologic findings demonstrated that the damage to the vasa vasorum of the adventitia resulting from AAV caused ischemia of the media, resulting in the formation of saccular aneurysmal changes...

A mycotic aneurysm that also involves the visceral arteries is a life-threatening condition. Surgical management typically consists of débridement and in situ repair with a Dacron graft and reimplantation of the involved visceral branches. We report a rare case of a mycotic saccular thoracoabdominal aortic aneurysm involving the celiac artery, with Streptococcus pneumoniae as the responsible organism. Successful repair of the aneurysm and concomitant revascularization of the celiac artery were achieved.

OBJECTIVE: Low wall shear stress (WSS) has been reported to be associated with accelerated atherosclerosis, aneurysm growth, or rupture. We evaluated the geometry of aortic arch aneurysms and their relationship with WSS by using the 4-dimensional flow magnetic resonance imaging to better characterize the saccular aneurysms. METHODS: We analyzed the geometry in 100 patients using multiplanar reconstruction of computed tomography. We evaluated WSS and vortex flow using 4-dimensional flow magnetic resonance imaging in 16 of them, which were compared with 8 age-matched control subjects and eight healthy young volunteers...
