Whole-body enhanced computed tomography of a septuagenarian woman hit by a truck revealed a traumatic aortic dissection (Stanford B) and arterial bleeding from the right lumbar artery in the right iliopsoas muscle. Angiography revealed an active arterial extravasation from a false lumen of the left lumbar artery. We performed a transcatheter arterial embolization (TAE) of the right lumbar artery. After fenestration of the intimal flap, the left lumbar artery was successfully selected and embolized; the patient's clinical condition subsequently stabilized...

A variety of syndromic diseases such as Marfan syndrome, Loeys-Dietz syndrome, and bicuspid aortic valve with aneurysm along with risk factors of smoking and hypertension result in ascending aortic aneurysms and dissections. Historically, a complicated variety of terms have been used to describe a range of histopathologies that are present in resected specimens. As a result, no consistent patterns of histopathology have been reported. We used the recent Society for Cardiovascular Pathology/Association for European Cardiovascular Pathology consensus statement on nomenclature and diagnostic criteria for noninflammatory aortic disease to blindly evaluate 148 surgically resected specimens...

BACKGROUND AND AIMS: Evidence on the association between passive smoking and risk of aortic dissection or aneurysm is limited. This study aimed to investigate whether passive smoking increases risk of mortality from aortic dissection or aneurysm. METHODS: The Japan Collaborative Cohort (JACC) Study is a prospective community-based cohort study begun in 1988-90 and followed up to the end of 2009. We examined 48,677 individuals (mean age, 56 years; women, 46%) without history of stroke, coronary heart disease, or cancer, who provided valid responses to a lifestyle questionnaire including questions on active and passive smoking...

OBJECTIVES: In vitro studies showed that lipophilic statins inhibit cell growth, adhesion, and invasion and induce apoptosis in cancer cell lines. In uterine cervical cancer, several important factors including age, stage, anemia, lymphovascular invasion, lymph node metastases, and parametrial spread were known to significantly predict survival. We investigated whether statin therapy as a prognostic factor would significantly predict survival in cervical cancer. METHODS: Patients with stages IB to IV cervical cancer who received radical hysterectomy and/or para-aortic lymph node dissection were included...

We present two cases of Amplatzer® device deployment that exhibited long-term failure necessitating surgical correction. The first case illustrates recanalization of a ruptured Valsalva aneurysm with worsening aortic insufficiency after percutaneous repair with the Amplatzer Vascular Plugs and Amplatzer duct occluder, while the second case illustrates recanalization after deployment of the Amplatzer septal occluder in a patient with a pseudoaneursym in a bovine aorta after type I aortic dissection repair. These two cases illustrate the potential long-term complications and limitations in durability with these devices...

Cardiovascular manifestations in patients with systemic lupus erythematosus (SLE) are common, but aortic aneurysm formation is rare. We present a 63-year-old male SLE patient with a two-year history of skin lesions, leucopenia, pericarditis, mitral valve vegetations consistent with Liebman-Sacks endocarditis, and an aneurysm of the ascending aorta, which was successfully repaired surgically. Histologic examination of the aneurysm showed medial cystic degeneration, smooth muscle necrosis, and mild adventitial perivascular lymphocytic aggregates...

BACKGROUND AND PURPOSE: Accurate diagnosis of acute aortic dissection (AAD) is sometimes difficult because of accompanying central nervous system (CNS) symptoms. The purpose of this study was to investigate the clinical characteristics of Type A AAD (TAAAD) with CNS symptoms. METHODS: We retrospectively reviewed the medical records of 8403 patients ambulanced to our emergency and critical care center between April 2009 and May 2014. RESULTS: We identified 59 TAAAD patients for the analysis (mean age, 67...

Thoracic endovascular repair is considered the first-line treatment in complicated acute type B dissection. Central venous catheters provide valuable vascular access during endovascular treatments. However, central venous catheters are not without complications. Herein, we report a case of central venous catheter insertion into the false lumen of a complicated acute type B aortic dissection by direct aortic puncture. The tip of the central venous catheter was in the false lumen. The central venous catheter was left in place initially and was removed after graft stent deployment...

Loeys-Dietz syndrome (LDS) is a rare connective tissue disorder (CTD) caused by mutations in the gene encoding transforming growth factor-β receptors Ⅰ and Ⅱ. Patients with LDS manifest spontaneous aneurysms and dissections of the aorta and peripheral artery. We report a successful treatment with a hybrid endovascular repair for a rapidly expanding thoracoabdominal aneurysm in a 41-year-old woman affected by LDS. To overcome the difficulties of anatomical and surgical repair, we applied an original strategy using surgeon-modified fenestrated endografts...

Takayasu arteritis is a panarteritis of unknown etiology involving the aorta and its main branches, with higher prevalence in women and peak of incidence in the second and third decades of life. Up to 30% of patients have coronary lesions and aortic valve involvement. Presentation mimicking aortic dissection is quite rare. Here described is the case of a young patient, presenting with an acute coronary syndrome associated with severe aortic regurgitation, who underwent emergent surgery with the suspicion of acute aortic dissection...

BACKGROUND: Esophageal perforation after aortic replacement/stenting for aortic dissection or aneurysm is a rare but severe complication. However, its cause, standard treatment, and prognosis are unclear. We analyzed the treatment and outcome retrospectively from seven cases experienced at our hospital. CASE PRESENTATION: The median age of the patients was 70 years (range, 41-86), and six of the seven cases were male. As the first treatment, aortic replacement techniques were performed in five, and thoracic endovascular aortic repair (TEVAR) procedure was performed in two...

History A 30-year-old man presented to the emergency department with epigastric pain. He was vomiting and in distress, and he had a history of thalassemia. Physical examination findings were unremarkable. Pertinent blood results were a hemoglobin level of 10.5 g/dL (6.52 mmol/L) (normal range, 13.5-18.0 g/dL [8.38-11.17 mmol/L]) and a bilirubin level of 62 µmol/L (normal range, 3-17 µmol/L). The remaining hematologic and biochemical results were normal. Aortic dissection was suspected clinically, so the patient was referred for imaging...
