Delayed coil migration after endovascular treatment with detachable coils, particularly several months after treatment, is extremely rare. In this report, the authors describe a 77-year-old female in whom delayed coil migration to the anterior cerebral artery and posterior communicating artery (PCoA) developed 3 months after an uncomplicated aneurysm embolization. The patient was successfully retreated with a closed-cell stent. Computational fluid dynamics (CFD) revealed high wall shear stress (WSS) and multiple vortices in the residual cavity of the initially treated aneurysm...

The diagnosis of brachiocephalic disease is often overlooked. Symptoms include arm claudication and vertebro-basilar insufficiency. In patients who have had the use of the internal mammary artery for coronary bypass surgery, the development of symptoms of myocardial ischemia should alert the clinician to the possibility of subclavian artery stenosis. Also in patients who have had axillo-femoral bypass, lower extremity claudication may occur. Recognition involves physical examination and accurate non-invasive testing...

The incidence of aneurysm after open surgical repair of coarctation is 11% to 24%. If the condition is left untreated, fatal rupture may occur. Thoracic endovascular aortic repair (TEVAR) has been reported as a feasible and safe alternative to open surgical repeated procedures in this context. However, TEVAR might be challenging because of the proximity of the pathologic condition to the supraaortic vessels and the ongoing presence of the coarctation. We report a unique case of a 48-year old man undergoing TEVAR because of aortic aneurysm after previous surgical coarctation treatment and successful closure of the coarctation with a vascular plug device...

We describe a very rare case of a 67-year-old man with multiple saccular aortic aneurysms throughout the entire aorta due to antineutrophil cytoplasmic antibody-associated vasculitis (AAV). The patient underwent staged aortic surgical procedures, including stent-graft insertion for a left iliac artery aneurysm, thoracic endovascular aortic repair for a descending aortic aneurysm, and total replacement of the ascending aorta and aortic arch with the use of high-dose steroids to control inflammation. The histologic findings demonstrated that the damage to the vasa vasorum of the adventitia resulting from AAV caused ischemia of the media, resulting in the formation of saccular aneurysmal changes...

Methylmethacrylate is a prosthetic material commonly used for the reconstruction of large chest wall defects. We present the first reported case of delayed methylmethacrylate plate migration, which resulted in an aortic pseudoaneurysm with aortopulmonary fistula. Treatment management, including staged repair combining endovascular and open approaches, is also discussed.

Endovascular repair of abdominal aortic aneurysms has widely replaced the open surgical repair due to its minimal invasive nature and the accompanying lower perioperative mortality and morbidity. During the past two decades, certain improvements and developments have provided a wide variety of endograft structural designs and geometric patterns, enabling the physician to approach a more patient-specific treatment of AAA. This review presents the currently available aortic endografts and describes the clinical, technical and mechanical characteristics of them...

OBJECTIVES: In patients with acute aortic dissection involving the arch and the descending aorta (AADA DeBakey type I), performing a total aortic arch replacement with the frozen elephant trunk (FET) procedure for supposedly better long-term results is still controversial. METHODS: From February 2004 to April 2016, 94 patients with AADA DeBakey type I had an FET procedure (80% men, age 58 ± 12 years). During the early period (Group 1, 2004-10), the FET technique was performed using non-branched grafts...

SummaryTreating complex aortic arch disease with proximal and distal aortic segment involvement is challenging. In recent years, different surgical and endovascular techniques have been applied in a single or multiple-stage approach with the aim to cure and simplify these conditions. The first procedure available for this purpose was the conventional elephant trunk technique. Its recent evolution is the frozen elephant trunk, which treats the descending thoracic aorta using the antegrade release of a self-expandable stent graft...

BACKGROUND: Endovascular recanalization of a completely occluded proximal internal carotid artery (ICA) with underlying stenosis may be challenging owing to a possible thrombotic component. This is especially true when the landing zone for a balloon-tipped guiding catheter (BGC) at the bulb portion is insufficient. Sequential application of the balloons of a BGC and an angioplasty catheter may prevent thromboembolism during revascularization. This study analyzed the safety and effectiveness of this relay-balloon technique...

OBJECTIVE: The effect of patient age on the likelihood of recurrence of ruptured aneurysms after endovascular coil embolization is not well understood. Our aim was to compare the incidence of aneurysmal recurrence after coiling between young and old patients. METHODS: We performed a retrospective cohort study on patients presenting to our institution with a ruptured intracranial aneurysm treated with endovascular coiling. Aneurysm recurrence was defined as a Modified Raymond Roy Classification (MRRC) grade of 3A or 3B on follow-up angiography performed on first follow-up angiography...

Air embolism is a rare but potentially fatal complication of surgical procedures. Rapid recognition and intervention is critical for reducing morbidity and mortality. We retrospectively characterized our experience with air embolism during medical procedures at a tertiary medical center. Electronic medical records were searched for all cases of air embolism over a 25-year period; relevant medical and imaging records were reviewed. Sixty-seven air embolism cases were identified; the mean age was 59 years (range, 3-89 years)...

OBJECTIVE Vascular malformations of the spine represent rare clinical entities with profound neurological implications. Previously reported studies on management strategies for spinal dural arteriovenous fistulas (sDAVFs) appeared before the advent of modern liquid embolic agents. Authors of the present study review their institutional experience with endovascularly and surgically treated sDAVFs. METHODS The authors performed a retrospective, observational, single-center case series on sDAVFs treated with endovascular embolization, microsurgical occlusion, or both between 2004 and 2013...

The aim of the present study was to observe the long-term prognostic value of early interventional therapy for lower extremity deep venous thrombosis (LDVT). In total, 85 patients diagnosed with LDVT for the first time were consecutively selected (identified course of disease was <3 months), and were divided into the control group with 43 cases and the observation group with 42 cases according to different therapeutic methods. The control group received anticoagulation therapy and thrombolysis, or integrated surgical thrombectomy, a conventional open operation, while the observation group received comprehensive treatment, combining endovascular catheter-directed thrombolysis and thrombectomy...

Posttraumatic external carotid artery pseudoaneurysm with arteriovenous fistula is a rare condition. An 8-year-old child presented with painful pulsatile swelling in the preauricular region following a penetrating glass shrapnel injury. Detailed evaluation showed distal external carotid artery pseudoaneurysm with fistula, which was draining into the retromandibular vein. Endovascular treatment was performed. This case highlights the role of endovascular intervention for such rare complicated vascular pathologies...
