BackgroundSpontaneous bilateral iliopsoas hematomas is a rare complication after anticoagulant therapy. Furthermore, the onset of bilateral iliopsoas hematoma is unknown because the causes are unclear.Case PresentationA 65-year-old man on anticoagulant therapy after mechanical aortic valve replacement was admitted after presenting with severe pain in the left flank and abdomen. Abdominal CT revealed a large left-sided iliopsoas hematoma with extravasation. Fresh frozen plasma was transfused due to prolonged prothrombin time. Transarterial embolization was successfully performed. During the hospital stay, follow-up abdominal CT was performed and a small right-sided iliopsoas hematoma was detected. This was closely observed and an intervention was not performed, as the patient was asymptomatic. The final CT prior to discharge revealed a reduction in size of each hematoma.ConclusionsSpontaneous bilateral iliopsoas hematoma can be developed subsequently. Patients with unilateral iliopsoas hematoma should be closely monitored for development of bilateral iliopsoas hematoma.

Neurofibromatosis type I (NF-1) induced vasculopathy is rare but catastrophic complication after aneurysmal rupture. We present the case of a 55-year-old female who developed hypovolemic shock because of left internal mammary artery (IMA) pseudoaneurysm rupture associated with NF-1. Even she was not detected NF-1 at the time of arrival in emergency room. We decided to perform percutaneous embolization instead of surgical approach. In this case, after intervention, the ruptured left IMA aneurysm was well treated. After 10 days, the patient discharged without any complications.

BackgroundVertebral artery variations are common in thoracic aortic patients. If patients have the aberrant left vertebral artery, the more difficult to determine the treatment modality.Case presentationWe report the case of a 63-year-old man with an aberrant left vertebral artery originating from an aneurysmal aortic arch. The patient underwent a successful hybrid thoracic endovascular aortic repair after aortic arch debranching and transposition of the aberrant left vertebral artery to the left common carotid artery through a supraclavicular incision without sternotomy.ConclusionsThe aberrant left vertebral artery originating from the aortic arch can be safely transposed to the left common carotid artery through a supraclavicular approach.

Coronary sinus ostial atresia is a rare disease. Most patients are usually asymptomatic and diagnosed incidentally during surgery or at autopsy. We report a case of coronary sinus ostial atresia with unroofed coronary sinus syndrome in a previously healthy woman who presented with infective endocarditis.

A 51-year-old male presented with blood-tinged sputum and a 40mmHg difference in pressure between the upper and lower extremities. A computed tomographic angiogram (CTA) of the chest showed a calcified and tortuous focal aneurysmal descending thoracic aorta with features of a coarctation (Fig. 1). There was dilatation of the bronchial and internal mammary arteries. At the time of surgery, the aorta

Cardiac tumor can produce a variety of symptoms and clinical findings depending on the location, size, and histologic type. It may cause heart failure usually by interfering with intracardiac blood flows associated with the mass effects. Here, we report an extremely rare case of heart failure caused by primary cardiac sarcoma with a review of the literature. The cause of heart failure was moderate to severe mitral steno-insufficiency due to the direct tumoral invasion of mitral valve apparatus combined with obstruction of the pulmonary veins.
