A 59-yr-old man presented with intraventricular hemorrhage and was found to have a large temporo-occipital arteriovenous malformation (AVM), Spetzler-Martin grade 4. The preoperative intra-arterial digital subtraction angiography (IADSA) showed the AVM was 4 × 4 cm2, had superficial and deep venous drainage, and was fed by multiple branches of the posterior cerebral artery and middle cerebral artery. Preoperative embolization was done in 4 stages. He underwent a left temporo-occipital craniotomy, mastoidectomy, and retrosigmoid craniotomy with a posterior temporal approach...

Polyarteritis nodosa is a chronic systemic vasculitis, characterized by the autoimmune, necrotising lesion of the walls of the small- and medium-bore visceral and peripheral arteries, resulting in vessel aneurysms and the secondary degeneration of organs and systems. All types of vessels (arteries, veins, capillaries) can be affected or, alternatively, the process can be limited predominantly to the vessels of one system, the clinical symptoms depending on the bore and location of the affected vessels. Varying degrees of the lesion, varying combinations and sequencing, the compensation abilities of the vessel disorders can blur the clinical picture, even though early pathomorphological changes are quite pronounced...

BACKGROUND: We report on the results of our endovascular aneurysm repair (EVAR)-first strategy for ruptured abdominal aortic aneurysms (RAAAs) focuses on Fitzgerald classification and vein thrombosis. MATERIALS AND METHODS: From 2011 to 2017, 31 patients with RAAA underwent EVAR at our hospital. We compared Fitzgerald (F)-1 patients (group A) with F-2-4 patients with obvious retroperitoneal hematoma (group B). RESULTS: The baseline characteristics in group A (n=9) and group B (n=22) were similar...

BACKGROUND: Arteriovenous malformation (AVM)-associated aneurysms are common, being reported in 15% of cases. In regards to ruptured posterior fossa AVMs, associated aneurysms are present in 48% of cases and are the etiology of the bleed in 37%. We present a 75 year-old female who presented with a subarachnoid hemorrhage (SAH) secondary to a ruptured aneurysm arising from a flow-related basilar perforator artery feeder of an anterior pontine AVM. We report the successful treatment of the aneurysm with coil embolization...

Background: Onyx® is a liquid embolic agent, which is approved for the treatment of cerebral vascular lesions but still rarely used in peripheral interventional radiology. The goal of this study is to report the feasibility and safety of embolization with Onyx® for peripheral hemostatic and non-hemostatic endovascular procedures. Methods: Retrospective study of all consecutive patients who underwent visceral or peripheral embolization with Onyx® for hemostatic or non-hemostatic purpose in our department between May 2014 and November 2016...

True infrapopliteal aneurysms occur very rarely; the majority of reported cases are secondary to trauma or infection. We report the development of a tibio-peroneal trunk (TPT) aneurysm 6 months after atherectomy and angioplasty and describe subsequent open surgical repair via a great saphenous vein bypass graft.

An arteriovenous fistula is a rare complication of ruptured abdominal aortic or iliac artery aneurysms (IAAs). Its clinical symptoms depend on its size, with signs of heart failure dominating if the fistula is large. Herein, we present a case of arteriovenous fistula with an unusual presentation. An 86-year-old male patient presented with extreme lower extremity edema, skin erosion, and continuous lymphorrhea (starting 3 months prior). Despite the large fistula between the right common IAA and the left common iliac vein after the rupture of the aneurysm, he did not develop heart failure symptoms, as the large shunt was predominantly directed toward the left lower extremity due to iliac vein compression...

INTRODUCTION: Endovascular aortic interventions are suitable alternatives to open surgery, being less invasive and having lower mortality and complications. Accurate positioning of the stent graft is a critical point because of systolic thrush. Techniques used to prevent it include pharmacological (antihypertensive drugs, nitroglycerin, adenosine) and mechanical methods (temporary caval occlusion by balloon). Rapid Right Ventricular Pacing (RRVP) is an emerging alternative with good patient tolerance and low level of complications...

INTRODUCTION: Renal artery aneurysm (RAA) is a rare clinical entity with an estimated prevalence of 0.15% to 0.1%in the general population. The majority of patients present asymptomatically and the diagnosis is made incidentally during a hypertension study test, and more rarely, fortuitously after backache. Indications to treat have been subject of intense debate, nevertheless there seems to be some consensus that RAAs greater than 2 cm in diameter, expanding RAA, with thrombus or in pregnant women should be treated...

INTRODUCTION: Brachial artery aneurysms are relatively uncommon and generally due to infectious, post-traumatic or iatrogenic etiology. They seem to affect 4.5% of arteriovenous fistula. The usual manifestation is an accidental finding of a pulsatile, painless, and asymptomatic mass. Complications include sac thrombosis, thromboembolic ischaemic events, and disruption with profuse bleeding. METHODS: The aim of this study is to present a case of true brachial artery aneurysm in end-stage renal disease patient after arteriovenous fistula creation...

INTRODUCTION: The aim of this study is to evaluate the outcome of catheter directed thrombolysis (CDT) in acute lower limb ischaemia depending on the underlying etiology. METHODS: Retrospective single center analysis of electronic clinical data on patients with acute lower limb ischaemia treated with CDT. Between January 2011 and September 2017, 128 procedures in 106 patients were included. The etiology of ischaemia was native artery thrombosis in 39 procedures (30,5%), PTFE graft thrombosis in 56 (43,8%), intra-stent thrombosis in 11 (8,6%), emboly in 9 (7%), popliteal aneurysm thrombosis in 9 (7%), vein graft thrombosis in 2 (1,6%) and popliteal artery entrapment in 2 (1,6%)...

INTRODUCTION: Subclavian artery pseudoaneurysms are rare and occur mostly as a consequence of an inadvertent arterial puncture during central venous catheterization, endovascular therapeutic procedures or after penetrating or blunt trauma. They usually have a late clinical presentation, with pain, swelling or other compressive symptoms. The optimal treatment in this situation is still a matter of debate. The authors describe a case of late presentation of subclavian artery pseudoaneurysm after transjugular hepatic biopsy and discuss the several options for treatment...

Atraumatic tension hemothorax is extremely rare. We report a case of 62-year-old woman presented with obstructive and hypovolemic shock status by tension hemothorax due to ruptured aneurysm of congenital intercostal artery-azygous fistula. Contrast-enhanced computed tomography and aortography revealed an aberrant 12th intercostal artery flowing into the aneurysm with a fistula draining into the azygous vein and the rupture of aneurysm. Our experience indicates that the rupture of congenital arteriovenous fistulas (AVFs) of systemic circulation in the thoracic cavity might cause not only hypovolemic shock but also atraumatic tension hemothorax...

Extracranial carotid artery aneurysms (ECAA) are a rare cause of embolic stroke. The underlying etiology is variable, with atherosclerosis being the most common entity in older subjects. Several treatments have been developed over the last 20 years, but the preferred method remains unknown. Notwithstanding the widespread use of endovascular techniques, surgical reconstruction by means of a bifurcated venous bypass graft should be applied in younger patients. In this way, it is possible to avoid major concerns about the development of long-term intrastent restenosis, and also to spare the external carotid artery which represents the main branch for the ipsilateral cerebral and facial perfusion...

Patients with cardiac disease have high mortality rates, mainly owing to shock. Therefore, evaluation of cardiac function is one of the most challenging issues in the intensive and critical care unit. Cardiac point-of-care tests using ultrasound, such as focus assessed transthoracic echo (FATE) and rapid ultrasound in shock (RUSH). are useful for diagnosis and initial care of such patients. The author will introduce first a basic FATE protocol of how to scan from position 1-4, including subcostal 4-chamber, apical 4-chamber, parasternal long and short axis, and pleural scanning...

We describe a case of a 44 year-old man with a subcutaneous swelling in the left popliteal fossa. The patient complained pain posteriorly to the left knee since several months and presented with a saccular aneurysm of the left popliteal vein (PVA) with reflux clearly evidenced at duplex ultrasound scan (DUS), but in absence of thrombus inside and without clinical signs of embolism. The patient was treated surgically by aneurysmectomy with lateral venorrhaphy according to Aldridge technique and a duplex ultrasound scan after six months revealed a complete patency of the left popliteal vein...

The use of kidney grafts with aneurysmal disease involving the renal arteries for transplantation is very uncommon and relatively controversial. We herein present the case of a 52-year-old woman who volunteered to become a living-nonrelated donor; during the preoperative imaging workup, a computed tomography angiography revealed a 1.5-cm saccular aneurysm in the left kidney, while the contralateral renal artery was normal. We decided to utilize the left kidney for a 25-year-old male patient with end-stage renal disease, and following the ex vivo repair using the recipient epigastric vessels and saphenous veins, we completed the transplantation in the right pelvic fossa...

Primary iliac venous aneurysm is an exceedingly rare abnormality that can be complicated by pulmonary embolism, thrombosis, and rupture. Here we report the case of an otherwise healthy 40-year-old man with a unilateral external iliac vein aneurysm without any evidence of an arteriovenous fistula, proximal stenosis, or obstruction, as reported on computed tomography. Pulmonary embolism was diagnosed using 99m Tc-macroaggregated albumin scintigraphy. To prevent life-threatening complications, we treated the patient with anticoagulant therapy and performed aneurysmectomy with reconstruction using a saphenous vein graft patch...

We present the case of a right internal iliac artery aneurysm with arteriovenous fistula in the posterior wall of the right common iliac vein. The fistula would have been difficult to close using endovascular treatment. We strongly anticipated difficulty in controlling bleeding; therefore, we performed cardiopulmonary bypass. Closing the fistula with suture would have been difficult, so we ligated the right common iliac artery and vein around the aneurysm. Femoro-femoral bypass was also performed to preserve blood flow in the lower right leg...

The combination of a double inferior vena cava (IVC), a retroaortic left renal vein, and azygos continuation of the IVC is extremely rare. Here we report the case of a 74-year-old man with this complex venous anomaly associated with a juxtarenal abdominal aortic aneurysm (AAA), who underwent a successful graft implantation with left renal artery reconstruction without injuring the retroaortic venous system. The venous anomaly was diagnosed using preoperative contrast-enhanced computed tomography (CT). Thus, contrast-enhanced CT can provide sufficient information on AAA and anomalous venous anatomy to avoid fatal complications during AAA surgery...
