Dissection of the internal carotid artery is very rare; however, it is diagnosed more frequently with increasing radiographic diagnostic tools. Patients may be completely asymptomatic or may present with symptoms ranging between localized pain to severe cerebral ischemic events. Treatment is usually medical or with interventional radiographic tools. In this report, we present surgical management of internal carotid artery dissection in a 61-year-old female patient.

Congenital aneurysm of the ascending aorta is a rare cardiovascular pathology and usually associated with well-known connective tissue disorders. We present an idiopathic ascending aortic aneurysm extending to the aortic arch in an antenatally diagnosed newborn who required immediate surgical treatment due to the rapid progression of aneurysm size at the age of 1 day.

Atherosclerosis is a systemic disease, and multiarterial involvement is common. Involvement of all the supra-aortic arteries may occur in the same patient making cerebral revascularization challenging. In this report, we present complete supra-aortic revascularization, that is, revascularization of the bilateral common carotid and subclavian arteries in a 51-year-old male patient with occluded brachiocephalic trunk, left subclavian artery, and proximally stenotic left common carotid artery. A temporary ascending aorta to left external carotid artery bypass provided meticulous cerebral protection with pulsatile cerebral flow in the presence of a proximal arterial clamp; hence, a neurologically uneventful procedure during bilateral common carotid artery revascularization.

Abstract Aim: Carotid artery stenosis and atrial fibrillation are diseases of the aging patient population. Literature lacks precise anticoagulation treatment protocols for patients with atrial fibrillation following carotid endarterectomy. We present our experiences with anticoagulation strategy in this particular patient population. Patients and methods: Between June 2001–September 2017, 165 patients with chronic or paroxysmal atrial fibrillation out of 1594 cases from three different institutions whom received Coumadin and aspirin and required carotid endarterectomy were reviewed, respectively. Mean age was 63.4 ± 7.9 years. Male/female ratio was 102/63. There were 67 diabetic and 138 hypertensive cases. Results: Patients are followed a mean of 64.4 ± 16.9 months. Early mortality occurred in two patients due to intracranial bleeding and heart failure. Another patient was lost due to intracerebral hemorrhage and 16 other patients died due to various causes in the late follow-up. Three patients required exploration against bleeding. Conclusion: Combination of warfarin with an aim to keep the INR value between 2 and 3, and aspirin at a dosage of 100 mg per day seemed feasible and in our modest patient cohort. Further studies including multicenter larger data are warranted in order to establish a precise anticoagulation treatment protocol for patients with atrial fibrillation after carotid endarterectomy.

Marfan syndrome is an inherited connective tissue disorder affecting mainly eyes and skeletal and cardiovascular systems. Cardiovascular involvement may lead to life-threatening aortic pathologies including aneurysms and/or dissections. In this report, the authors present images of a patient with Marfan syndrome with a history of Bentall-De Bono procedure followed by aortic arch and infrarenal aortoiliac replacements who strongly refused conventional open repair and underwent abdominal debranching followed by thoracoabdominal endovascular stent grafting for the treatment of thoracoabdominal aneurysm.

Chronic atherosclerotic mesenteric ischemia is a debilitating disorder. It may cause postprandial abdominal pain leading to severe weight loss. Patients are usually emotionally affected with major depression. The disease can be treated with open surgical and endovascular techniques and both methods have individual risks and benefits. In this report, the authors present anatomical revascularization of the superior mesenteric artery and the celiac trunk.

Treatment of thoracic aortic aneurysms constitutes high mortality and morbidity rates despite improvements in surgery, anesthesia, and technology. Endovascular stent grafting may be an alternative therapy with lower risks when compared with conventional techniques. However, sometimes the branches of the aortic arch may require transport to the proximal segments prior to successful thoracic aortic endovascular stent grafting. Atherosclerosis is accounted among the etiology of both aneurysms and occlusive diseases that can coexist in the same patient. In these situations stent grafting may even be more complicated. In this report, we present the treatment of a 92-year-old patient with aortic arch aneurysm and proximal descending aortic aneurysm. For successful thoracic endovascular stent grafting, the patient needed an alternative route other than the native femoral and iliac arteries for the deployment of the stent graft. In addition, debranching of left carotid and subclavian arteries from the aortic arch was also required for successful exclusion of the thoracic aneurysm.

Dacron grafts are frequently used during surgical revascularization procedures. Complications including graft thrombosis and infection are well known; however, aneurysm formation is extremely rare. In this report, we describe dilatation of a Dacron graft detected four years after aortobifemoral bypass procedure in a 50-year-old male patient who was treated with endovascular stent grafting.

Mediastinal cysts are extremely rare clinical disorders. They usually have a pericardial origin. In this report, we present a 27-year-old male patient with a mediastinal bronchogenic cyst together with clinical presentation and management of the pathology.
