BACKGROUND: Standard endovascular therapy has shown little success in treatment of very large and giant ophthalmic segment aneurysms. We hypothesize that surgical treatment of these aneurysms yields better results in terms of visual function and aneurysm obliteration. METHODS: The Toronto Brain Vascular Malformation Study Group database was analyzed to retrieve ...

We assessed the potential safety of withholding treatment of pulmonary embolism (PE) limited to subsegmental branches. Literature review showed that untreated patients with mostly subsegmental PE had no fatal recurrences in 1 to 3 months and no nonfatal recurrences of PE in 3 months. Patients with suspected PE who had ...

A perimesencephalic subarachnoid hemorrhage refers to the presence of bleeding around the midbrain with a normal angiography, meeting the well established clinical criteria and radiological criteria. Unlike the aneurysmal subarachnoid hemorrhage, it has a good prognosis, the recovery in most cases being complete and satisfactory. On the other hand, between ...

In-stent reocclusion is a frequent complication of endovascular treatment and stenting, especially in the superficial femoral artery. Neointimal hyperplasia is the main cause of this problem, but in many cases, it occurs as a result of the presence of stent strut fractures. The two treatment options are endovascular and surgical ...

In addition to classic aortic dissection and intramural hematoma, acute aortic syndrome also includes penetrating aortic ulcers (PAU). The recent advent of highly detailed axial imaging allows closer assessment of PAU and its pathophysiology. However, there is still ongoing discussion about the natural history of the disease, leading to challenging ...

Prevention of late cardiovascular complications after radiation therapy (RT) for treatment of a malignant tumor is challenging. We report the case of a young male patient with Hodgkin's lymphoma treated with RT, who developed ischemic heart disease during follow-up, although he had no cardiovascular risk factors. We conclude that patients ...

Optimal management of renal artery atherosclerotic occlusive disease has been widely debated and studied. Although the accepted invasive treatment has evolved into favoring balloon angioplasty and stenting, the indications for intervention or medical therapy have not been universally agreed upon. The Angioplasty and Stenting for Renal Artery Lesions (ASTRAL) trial ...

Coronary angiography (CAG) was performed in a 77-year-old woman who presented with chest discomfort. The CAG showed two diseased vessels. For treatment, the patient underwent angioplasty and stenting. During intravascular ultrasonography (IVUS) following stent deployment, the IVUS catheter became entrapped in the left anterior descending coronary artery, causing ischemic changes ...

The main treatment for acute arterial ischemic stroke is intravenous or intra-arterial thrombolysis within a particular time window. Endovascular mechanical embolectomy is another treatment option in the case of major artery occlusion. Endovascular mechanical embolectomy is a useful technique for restoring blood flow in patients with large-vessel occlusion, and especially ...

The treatment of calcified coronary artery lesions is a challenge for percutaneous angioplasty. Rotational atherectomy is an established technique for the effective modification of these lesions prior to conventional angioplasty and stent implantation. Drug-eluting stents (DES) have shown encouraging results in complex lesions and high-risk patients. This retrospective study investigated ...

Intracranial aneurysms (IAs) require deliberately selected treatment strategies as they are incrementally found prior to rupture and deleterious subarachnoid haemorrhage (SAH). Multiple and recurrent aneurysms necessitate both neurointerventionalists and neurosurgeons to optimize aneurysmal occlusion in an interdisciplinary effort. The present study was conducted to condense essential strategies from a single ...

In the present study we tested the hypothesis whether hyperhomocysteinemia, an elevated homocysteine level, induces venous phenotype in artery. To test our hypothesis, we employed wild type (WT) and cystathionine β-synthase heterozygous (+/-) (CBS+/-) mice treatment with or without folic acid (FA). Aortic blood flow and velocity were significantly lower ...

SUMMARY: In this report, we present the fatal spontaneous delayed rupture of a previously unruptured large PICA aneurysm following treatment with the PED. Pathology at postmortem examination has supported the theory that intra-aneurysmal thrombus may acutely destabilize the aneurysm wall. Aneurysms with an anatomic arrangement that promote continued flow into ...

Coronary stents have been used for the treatment of patients with coronary artery disease (CAD), and significantly improved procedural safety and are associated with a lower rate of restenosis compared with balloon angioplasty alone. Drug-eluting stents (DES) have been dominant for the treatment of CAD with efficacy in significantly reducing ...

Background:Inflammatory pseudotumours are mostly seen in the lung, and occasionally in the head and neck region including the sinonasal area. Reported treatment modalities comprise corticosteroid treatment, surgical excision and radiotherapy. The latter option is required because wide surgical resection may be difficult for head and neck lesions, especially in children. ...

The purpose of this study was to evaluate the incidence of inaccurate stent positioning in the treatment of coronary aorto-ostial lesions. The percutaneous treatment of aorto-ostial disease is challenging, with a paucity of data describing the incidence of stent mispositioning. We retrospectively reviewed the accuracy of stent positioning in 100 ...

Cerebral aneurysms of an infectious etiology, so-called "mycotic" aneurysms, are rare neurovascular pathologies. Primary treatment may be targeted on the aneurysm, but care has to be driven by the underlying pathology to prevent an often fatal clinical course with a mortality rate reaching 90%. 2 case reports are presented, and ...

Venous thromboembolic disease is associated with significant morbidity and mortality. Anticoagulation has been the mainstay of treatment and prevention. Unfortunately, anticoagulation frequently fails or is contraindicated. Use of inferior vena cava filters can be an effective alternative in these scenarios. Though inferior vena cava filters have been used for > ...

Percutaneous atherectomy provides an alternative approach to the endovascular treatment of peripheral atherosclerotic occlusive disease beyond angioplasty and stenting, and has the theoretical advantage of lesion debulking and minimizing barotrauma to the vessel wall. Atherectomy has evolved greatly during the last decade, with currently four FDA approved devices for the ...

Anatomical constraints limit the utility of endovascular therapy with infrarenal stent grafts in approximately 40% of the patients. Fenestrated and branched stent grafts that incorporate the visceral and renal arteries are currently not approved for commercial use in the United States and require at least 6 to 8 weeks for ...

Morbidity and mortality after conventional open repair of post-dissecting thoracoabdominal aortic aneurysms (TAAA) remain high despite the improvement of results. Recently, "hybrid" open de-branching procedures combined with endovascular stent-grafting of the atherosclerotic thoracic aortic aneurisms have been performed, as an alternative approach. However, patients with significant cardiac, pulmonary or renal ...

Bilateral traumatic carotid-cavernous fistulae (TCCFs) is rarely encountered neurovascular disease. For treatment of TCCF, detachable balloons have been widely used. Nowadays, transarterial and/or transvenous coil embolization with placement of covered stents is adopted as another treatment method. We experienced a patient with a bilateral TCCFs who was successfully treated with ...

An azygos vein aneurysm is a very rare cause of a posterior mediastinal mass. Once the diagnosis has been confirmed, no treatment is usually required. However, the aneurysm can thrombose, and this may lead pulmonary thromboembolism, or the aneurysm may rupture. In these instances, the excision of the mass is ...
