Left ventricular pseudoaneurysm is especially rare in childhood, and its main treatment option should be surgery. We describe the case of a 9.5-year-old boy who first underwent mitral vegetation excision and then an unsuccessful pseudoaneurysm operation. Owing to pseudoaneurysmal sac dimensions, inferior caval vein syndrome developed. We delivered the Amplatzer ...

The introduction of flow diverters for treatment of intracranial aneurysms represents a major paradigm shift in the treatment of these lesions. The theoretical hallmark of flow diverters is the treatment of the diseased segment harboring the aneurysm instead of treating the aneurysm itself. Flow diverters are designed to induce disruption ...

Treatment with statins improves clinical outcome, but the exact mechanisms of pleiotropic statin effects on vascular function in human atherosclerosis remain unclear. We examined the direct effects of atorvastatin on tetrahydrobiopterin-mediated endothelial nitric oxide (NO) synthase coupling in patients with coronary artery disease. We first examined the association of statin ...

Lower extremity deep venous thrombosis (DVT) has traditionally been divided into proximal and distal DVT. Proximal DVT is further subdivided into iliofemoral DVT, involving the common femoral vein and/or iliac vein, and represents an obstructive disease process with a worse prognosis than proximal DVT without involvement of these large draining ...

Thoracic endovascular aortic repair (TEVAR) has been one of the most important advances in the management of thoracic aortic disease in the past two decades. The procedure was originally developed by Dake and colleagues in 1994 for the treatment of descending thoracic aortic aneurysm (DTAA), using the same principles as ...

Central venous catheter occlusions disrupt delivery of needed therapies to vulnerable neonatal and young pediatric patients. Nursing practices that minimize risk of catheter occlusion include proper infusion and flushing techniques. Treatment strategies vary on the basis of the source of the occlusion. Mechanical occlusions can often be resolved by altering ...

Osseous sarcoidosis is relatively uncommon, and treatment with corticosteroids is not always effective. Moreover, patients with an advanced stage of pulmonary sarcoidosis are sometimes infected with aspergillus in the cavities of the pulmonary lesions, and long-term use of corticosteroids should be prohibited to prevent the development of fatal invasive pulmonary ...

Descending thoracic dissections originating distal to the origin of the left subclavian artery carry a significant mortality if left untreated. Past thinking advocated avoiding surgical treatment of acute Stanford type B or DeBakey type III dissections, reserving therapy for chronic dissections over 14 days to a month after presentation. The ...

Pulmonary sequestration is a rare congenital malformation whose origin is bronchial and arterial simultaneously and its vascularization comes from an anomalous systemic artery. Its clinical presentation includes recurrent pneumopathy in the same anatomic location of the lung and difficult to resolve or recurrent lung abscess. It is usually treated with ...

In early embryologic development the sciatic artery provides the blood supply to the lower limb bud. When the femoral artery develops, the sciatic artery involutes. However, in rare cases, the sciatic artery persists. It can be visualised as a prolongation of the inferior gluteal artery (branch of the internal iliac ...

Congenitally corrected transposition of the great arteries (ccTGA) is a complex cardiac anomaly with an unfavorable natural history. Surgical treatment has been available for over 50 years. Initial procedures used for ccTGA did not correct atrio-ventricular discordance, leaving the right ventricle in systemic position. In the past two decades anatomic ...

Unruptured intracranial aneurysms (UIA) are increasingly treated with endovascular treatment although this method continues to be associated with aneurysm recurrences in up to 30-40%, especially for large aneurysms or those with wide (>4 mm) necks. Although the significance of a recurrence remains unknown, they not only require angiographic follow-up but ...

Intracranial stenosis is associated with a high risk of ischemic events, even with medical treatment. Percutaneous transluminal angioplasty and stenting (PTAS) is an accepted intervention for addressing a moderate intracranial stenosis (≥50%) that is refractory to medical treatment. Distal emboli are seen in 34% to 70% of patients on MRI ...

An 86-year-old female was incidentally discovered with an asymptomatic 5.3 cm infrarenal aortic aneurysm. Preoperative imaging demonstrated the aortic neck to have severe suprarenal and infrarenal angulation. The patient was deemed unfit for open aortic repair due to multiple medical comorbidities. Endovascular treatment was performed with a modified Zenith bifurcated ...

Traditional therapy for pulmonary embolism includes systemic anticoagulation, systemic thrombolysis, catheter-directed thrombolysis / suction catheter thrombectomy, and surgical thromboembolectomy. Currently, the standard treatment for submassive and massive pulmonary embolism involves the use of systemic anticoagulation. However, unlike systemic anticoagulation there is no standard treatment algorithm for the use of thrombolytics ...

The Ross procedure or pulmonary autograft has been frequently used for surgical treatment of aortic valve disease. One considerable disadvantage of the Ross procedure is the involvement of two valves (aortic and pulmonary) in treatment of single (aortic) valve disease. Both the aortic and pulmonary valves are at risk for ...

Left aortic arch with aberrant right subclavian artery is the most common congenital vascular anomaly involving the aortic arch. In 60% of cases, the aberrant right subclavian artery arises from a dilated segment of the aortic arch called Kommerell's diverticulum. Aneurysm of the aberrant right subclavian artery is rare; this ...

Renal artery aneurysms (RAA) are rare (general population incidence is 0.09%). At this time, the appropriateness of the type of intervention ‑ surgical or endovascular ‑ is based on single center experiences rather than large randomized trials. Endovascular therapy offers less morbidity but surgery has excellent long-term results. In reality, ...

Perioperative optic neuropathy is a disease which can lead to serious, irreversible damage of vision. This complication could be the result of non-ocular surgery, for example, cardiac or spinal procedures. We present a case of anterior ischemic neuropathy (AION) which occurred following a conventional coronary artery bypass graft procedure. A ...

Carotid blowout is a devastating complication in patients with head and neck malignancy. Various treatments including high risk surgery, carotid stenting or carotid occlusion using either coils or detachable balloons have been described. The key for any treatment is the rapidity at which it can be performed. We describe treatment ...

Arterial ischemic stroke occurs as a result of abnormal clinical circumstances that alter hemostasis and cause thrombosis, either within a vessel or as an embolic event. Understanding normal hemostasis, including differences between children (developmental hemostasis) and adults, will provide background for determining the pathophysiology of stroke and potential treatments.

Thoracic endovascular aortic repair (TEVAR) is an important surgical option for the emergency treatment of ruptured thoracic aortic aneurysms, but is associated with a risk of spinal cord ischemia (SCI). Although risk factors for the development of SCI have been well described, the effectiveness of treatment to increase spinal cord ...
