Disseminated intravascular coagulation (DIC) is an acquired coagulation disorder that occurs when the normal hemostatic balance is disturbed, primarily by excessive thrombin formation. Moreover, while DIC is a rare complication of aortic dissecting aneurysm, it is also a well-recognized one. We reported a case of DIC associated with aortic dissecting aneurysm in a 55-year-old woman who was transferred from another hospital because of chest pain radiating to her back and thrombocytopenia. Laboratory findings showed DIC with severe thrombocytopenia, and she was diagnosed as having an acute aortic dissection and DIC. After medical treatment on the aortic dissecting aneurysm, her DIC profile recovered.

Azygous vein aneurysm is a rare congenital lesion that needs to be differentiated from mediastinal mass lesions. Although almost of these anomalies are asymptomatic lesions, we experienced an interesting case in which a thrombus within an azygous vein aneurysm in a 75-year-old woman caused pulmonary thromboembolism. The patient was managed by medical treatment for one month and then the thrombus within both the azygous vein aneurysm and the pulmonary arteries completely resolved.

Simultaneous occurrence of aneurysmal subarachnoid hemorrhage (SAH) and hypertensive intracerebral hemorrhage (ICH) is very rare and only two cases have been previously reported in the literatures. We present a case of 68-yr-old man with a history of untreated hypertension, who suffered from sudden onset of headache followed by right hemiparesis. Computed tomographic (CT) scan revealed SAH in the basal cistern and remote ICH at the left putamen. Cerebral angiography showed a saccular aneurysm at the anterior communicating artery. No other vascular anomaly could be found at left putaminal area. Nine days after the ictal attack of SAH, the neck of aneurysm was clipped via the left frontotemporal craniotomy. Because of the ICH at the left frontal lobe and intraventricular hematoma on postoperative CT, we performed hematoma removal and external ventricular drainage 3 hours after the first operation. Postoperative neurological status had been improved to be drowsy and he was discharged in a severely disabled state 4 weeks after surgery. We suggest that the rupture of aneurysm possibly caused a rapid increase in blood pressure and subsequently resulted in hypertensive ICH.

Although pulmonary artery aneurysms are a rare vascular anomaly, they are seen in a wide variety of conditions, such as congenital heart disease, infection, trauma, pulmonary hypertension, cystic medial necrosis and generalized vasculitis. To our knowledge, mycotic aneurysms caused by pulmonary actinomycosis have not been reported in the radiologic literature. Herein, a case of pulmonary actinomycosis complicated by mycotic aneurysm is presented. On CT scans, this case showed focal aneurysmal dilatation of a peripheral pulmonary artery within necrotizing pneumonia of the right lower lobe, which was successfully treated with transcatheter embolization using wire coils.

We report herein a case successful endovascular treatment with a stent-graft of a rare case of rapidly growing mycotic aneurysm of the left common carotid artery due to acute bacterial endocarditis after eradication of the infection. Infected mycotic aneurysms of the peripheral vasculature have been considered as a contraindication for stent-graft implantation because of the possibility of microorganism spreading to the stent-graft; however, if there is evidence of complete eradication of microorganism and surgery is not an option, stent-graft implantation can be an effective and safe treatment modality for exclusion of the mycotic aneurysm.

There have been reports of the coexistence of abdominal aortic aneurysm (AAA) with intra-abdominal malignancy including gastric, colonic, pancreatic, and renal. We herein report a case of a previously undiagnosed AAA and a presenting complaint consistent with acute cholecystitis. Following cholecystectomy, this was noted to be a rare form of chronic cholecystitis: xanthogranulomatous cholecystitis. There is a known possible association of this uncommon condition with gallbladder cancer. The management of concomitant pathologies can present a real challenge to the multidisciplinary team, especially with large aneurysms.

Chest trauma can lead to various cardiac complications ranging from simple arrhythmias to myocardial rupture. An acute myocardial infarction (AMI) is a rare complication that can occur after chest trauma. We report a case of 66-year-old male who suffered a blunt chest trauma from a traffic accident resulting in an AMI. The coronary angiography revealed an eccentric 50% narrowing of the ostium of left anterior descending artery (LAD) by a dissection flap with calcification. Intravascular ultrasonography (IVUS) revealed eccentric calcified plaque (minimal luminal diameter [MLD]=3.5 mm) with a dissection flap. Intervention was not performed considering the MLD and calcified flap, and he has been conservatively managed with aspirin and losartan for 2 years. The follow-up coronary angiography showed an insignificant luminal narrowing of the proximal LAD from the ostium without evidence of a dissection. An early coronary evaluation including an IVUS study should be considered for managing patients who complain of ongoing, deep-seated chest pain with elevated cardiac enzyme levels and an abnormal electrocardiogram (ECG) after a blunt chest trauma. Based on this case, some limited cases of traumatic coronary artery dissections can be healed with conservative management and result in a good prognosis.

The rupture of an acute dissection of the ascending aorta into the space surrounding the pulmonary artery is an uncommon occurrence. No previous cases of transient pulmonary hypertension caused by a hematoma surrounding the pulmonary artery have been documented in the literature. Herein, we report a case of acute aortic dissection presenting as secondary pulmonary hypertension.

Intrathoracic segment of the subclavian artery is an unusual location for peripheral arterial aneurysms. They are normally caused by atherosclerosis, medial degeneration, trauma, and infection. We report a case of a patient with right subclavian artery aneurysm presenting with hoarseness. Chest radiograph demonstrated a superior mediastinal mass. Laryngoscopy showed a fixed right vocal cord. By chest computed tomography, magnetic resonance imaging, and angiography, preoperative diagnosis was established as a saccular aneurysm with afferent loop and efferent loop. Patient underwent complete resection of the aneurysm followed by endto-end anastomosis via median sternotomy. Postoperative pathology was consistent with an atherosclerotic aneurysm filled with thrombus. After surgical operation, hoarseness is still continued.
