Objective: The objective of this work is to evaluate the long-term results of endovascular treatment of popliteal artery aneurysms with a stentgraft. Methodology: In the period from June 2011 to December 2023, 66 patients with popliteal artery aneurysm were treated endovascularly at our institution with stentgraft implantation, 60 men and 6 women aged 51 to 90 years, the median age was 70 years. The length of follow-up was 1-128 months, the average follow-up time was 50 months. Patients were regularly observed using doppler imaging, a plain radiograph of the stentgraft and check-ups by a vascular surgeon. Primary and secondary patency of stentgrafts was retrospectively evaluated. Other monitored parameters were the coincidence of bilateral aneurysm of the popliteal artery, aneurysm of the abdominal aorta, integrity failure of the stentgraft skeleton, or the occurrence of migration or collapse of the stentgraft. Results: In our group, the technical success rate was 100%. One-year, three-year, and five-year primary patency rates were 78%, 68.2%, and 61%. Secondary patency rates were 94.8%, 88.6% and 80.5%. According to Kaplan-Maier analysis, the probabilities of primary patency at one, three and five years were 67.4-88.5%, 56.0-80.5%, 46.5-75.5%, and the probabilities of secondary patency at one, three and five years 89.1-100%, 80.0-97.3%, 67.3-93.8%. Stentgraft migration occurred once, collapse also occurred once, and stentgraft integrity failure occurred seven times. The coincidence of bilateral involvement of popliteal artery aneurysm was detected twenty-six times, and the simultaneous occurrence of abdominal aortic aneurysm sixteen times. Conclusion: Endovascular treatment of popliteal artery aneurysm is a simple and safe method that provides acceptable long-term patency. [ABSTRACT FROM AUTHOR]

We present a successful urgent endovascular treatment of symptomatic endoleak (EL) 7 years after primary implantation of a bifurcation stent graft (SG) into abdominal aortic aneurysm in an elderly, polymorbid man with solitary kidney. Combined parallel insertion of a renal SG from the brachial approach and proximal extension of distally migrated SG from the femoral approach resulted in the resolution of type IA EL while preserving perfusion of the solitary renal artery. Subsequently, the apparent type II EL was successfully treated by direct, transabdominal injection of thrombin into the aneurysm sac. At follow-up 8 weeks after thrombin application, the patient was free of EL and associated clinical symptoms. [ABSTRACT FROM AUTHOR]

Hemodynamic parameters play a significant role in the development of intracranial aneurysms and their time-depending changes during a prolonged follow-up period could lead to an increasing risk of rupture or to aneurysm rupture. The characteristics of these changes could bring significant information about the development of aneurysms and their rupture. In this unique study, we analyzed four incidental unruptured intracranial aneurysms in four patients who were followed-up for a mean period of 5 years until their rupture. We performed computational fluid dynamic simulations with the data from two or three follow-up angiographic examinations from each patient and analyzed the results with regard to time-dependent changes in terms of the values of hemodynamic parameters. Except one aneurysm of a fusiform dissecting origin, three aneurysms on MRA were described as non-growing. In the aneurysm domes, the minimal wall shear stress decreased and the low wall shear stress area increased significantly over time; the results indicated that the time-dependent changes such as decreasing values of minimal wall shear stress and increasing values of low wall shear stress area could lead to an increased risk of rupture. For accurate evaluation of the rupture risk using computational fluid dynamic simulation, it is important to analyze more than two models of aneurysm during a follow-up period and focus on significant changes in the values of hemodynamic parameters.

We present a case of a patient with a newly diagnosed vasculitis of polyarteritis nodosa, that manifested itself by macroscopic hematuria, secondary hypertension and multiple infarctions in both kidneys. Imaging methods revealed multiple small aneurysms of the renal arteries that caused occlusion of their segmental branches and consequently led to partial ischemia of the parenchyma. Asymptomatic aneurysms on branches of proper hepatic artery and dissection of left common and external iliac artery were also diagnosed. Digital subtraction angiography is considered to be the gold standard of imaging in polyarteritis nodosa, although it could be replaced by CT angiography due to its rapid advances.

Coronary artery ectasia (CAE) is a rare clinical condition which represents a form of atherosclerotic coronary artery disease. It is defined as dilatation of the coronary artery 1.5 times greater than that of an adjacent normal segment of coronary artery (1). This entity has been reported in patients undergoing coronary angiography from 3 % to 8 %, alone or in combination with stenotic lesions. The rate of recognition may increase with the use of new non-invasive imaging methods like computed tomography (CT) and magnetic resonance (MR) coronary angiography. The clinical significance of CAE is not very well defined and the results have been mixed and conflicting (2,3). As the main etiologic factor responsible for CAE is atherosclerosis, there are other factors involved in different groups of patients. The objective of this article is to review and examine the clinical characteristics of CAE, diagnosis, treatment and its prognosis. Also the purpose of this review is to update and to summarize the clinical features of CAE. [ABSTRACT FROM AUTHOR]

Only limited data are available on the extent of the vasa vasorum of the human thoracic aorta, although this could be important with regard to certain pathophysiological states, i.e. aortic aneurysm or atherosclerosis. A preliminary investigation shows that the vascularization of the human thoracic aorta reaches deeper layers than generally believed. [ABSTRACT FROM AUTHOR]

Internal jugular central venous line placement is a standardized and common clinical procedure. However, even the most skillful physician may face complications. Careful patient evaluation and detailed vascular anatomical knowledge can minimize the risk of iatrogenic injuries. Following a strict protocol in case of unsuccessful attempts of venous puncture helps to improve patient outcome. In this case report, we present a patient who suffered an unusual injury. Further, we discuss current treatment options for pseudoaneurysms. [ABSTRACT FROM AUTHOR]

We report a 65 year old patient who presented with both an aneurysm of the axillary artery and, some years later, with an acute aortic dissection type Stanford A. After surgical intervention of the dissection in the further workup, no specific etiology could be found. The most likely reason for the two aneurysms was the inadequately treated hypertension. Therefore, follow-up strategies aim to treat the risk factors which are known to promote aneurysm growth. [ABSTRACT FROM AUTHOR]

The incidence and operations of thoracic and thoracoabdominal aortic aneurysms have significantly increased. The indications for repair are considered to be a diameter of 6 cm or more and 5.5 cm for patient groups with increased risk of rupture. Complex open surgical repair is associated with significant mortality and complication rates. Total or hybrid endovascular repair seems to reduce early postoperative complications and mortality. The endovascular approach has evolved to be a good and predominant alternative to open repair of these aneurysms for older and high-risk patients as well as for aneurysms with optimal morphological suitability. Notwithstanding, at present a complete paradigm shift from open to endovascular repair for all patients, especially those with complex aneurysms, cannot yet be established. [ABSTRACT FROM AUTHOR]

Background: The integration of hybrid operation theatre into neurosurgical and neuroradiological routines is revolutionizing in particular the management of neurovascular emergencies, such as subarachnoid aneurysmal hemorrhage (SAH) or ruptured arteriovenous malformations. Results: The direct interaction between neurosurgeons and neuroradiologists in a joint environment changes and accelerates all diagnostic and therapeutic steps because all relevant procedures, including treatment control can be performed in a single room. Interventions of the skull base or the spine are also a domain of such hybrid theatre. Conclusion: As this new concept requires organisational changes throughout the entire patient management, a change of mindset is also needed at the institutional level in order to attain maximum benefits from such a setting.

In the last 10 years interventional neuroradiology has become established especially in the endovascular treatment of aneurysms as the preferred treatment according to level 1 evidence and more recently in the treatment of acute ischemic stroke. These interventions are performed as routine procedures in an increasing number of centers. This, however, necessitates that anesthesiologists and neuroradiologists become increasingly more familiar with the complementary expectations and potential pitfalls in working together to maximise efficiency and patient safety. As a further challenge there are different aspects to be considered in elective procedures and emergency procedures where time is brain. This article highlights these aspects for the two most common procedures: aneurysm treatment and multimodal recanalization treatment for acute ischemic stroke. [ABSTRACT FROM AUTHOR]

Aneurysms of the popliteal artery are the most common form of peripheral aneurysm with an incidence of 70-80 %. An enlargement of the popliteal artery of more than 50% of the original diameter is defined as a popliteal artery aneurysm and is found mainly in male patients older than 65 years of age. The incidence is 1%, in 50% of cases is bilateral and in up to 50% in association with other large vessel aneurysms (e.g. abdominal aorta). Differential diagnoses are Baker's cyst, cystic adventitial disease, entrapment syndrome and epitheloid hemangioma. One third of all diagnosed popliteal artery aneurysms are asymptomatic incidental findings, whereas two thirds are conspicuous due to symptoms (acute or chronic ischemia, local compression, rupture). The indications for invasive treatment are given for patients with patent aneurysms at a diameter of more than 2 cm or if a thrombus is present within the aneurysm. Symptomatic popliteal artery aneurysms are always an indication for therapy. Treatment strategies are surgical techniques and endovascular interventions, which both have a similar outcome and graft patency in midterm results. [ABSTRACT FROM AUTHOR]

The choice of potential options for an arteriovenous (AV) access is limited for each individual patient. Complications shorten the maximum life span of any AV access. This paper stresses the importance of recognizing complications in time so as to initiate early and adequate therapy which are explained in further detail. Existing vascular accesses should be used as long as possible while maintaining further alternatives for future AV access surgery. [ABSTRACT FROM AUTHOR]

The diagnosis, management and long-term implications of non-traumatic subarachnoid hemorrhage continue to be a multidisciplinary challenge. Often, the patients present to emergency or primary care physicians not particularly experienced in the differential diagnosis of headache. In most cases of a proven hemorrhage (aneurysm rupture in 85%), further treatment will require the discussion between experienced neurosurgeons and neuroradiologists whether to 'clip or coil'. Thus, subarachnoid hemorrhage is the first cerebrovascular disorder where a multidisciplinary approach has become the evidence-based standard of care. Patients with this condition are relatively young, and the survivors have a good life expectancy. Their neurologic, cognitive and psychiatric morbidity, risk of recurrent bleeding and elevated risk of other vascular diseases remain underestimated tasks for long-term care. [ABSTRACT FROM AUTHOR]
