    Full Text Available Objective To discuss the individualized management strategy for intracranial vertebral artery dissecting aneurysms. Methods Eighteen patients with intracranial vertebral artery dissecting aneurysms were treated with different surgical methods. Results Eighteen patients underwent different surgical treatment. Five patients underwent complete occlusion of the aneurysm and parent artery by coiling, 5 were treated by stent -assisted coiling (3 densely packed coiling and 2 non-densely packed coiling, 4 underwent stent-only therapy and 3 of them presented hemodynamic improvement after surgery, 3 were treated by direct surgical clipping, and 1 underwent occipital artery-posterior inferior cerebellar artery bypass. Two aneurysms ruptured immaturely, in which one patient died on the third day after operation and one patient occurred moderate disablity. Only 1 patient who underwent complete occlusion of aneurysm and parent artery presented temporarily ischemic symptoms. No adverse effects were seen in other patients. Seventeen patients were followed up for 1 month to 3 years, and all the aneurysms were stable. Conclusion There are many kinds of therapeutic methods for intracranial vertebral artery dissecting aneurysms. The patients should be treated according to several factors such as the clinical manifestations, aneurysm configuration, and relationship with the posterior inferior cerebellar artery. The treatment should be individualized.

    Summary We evaluated the outcomes of endovascular or surgical treatment of ruptured vertebral artery dissecting aneurysms (VADAs), and investigated the relations between treatment complications and the development and location of the posterior inferior cerebellar artery (PICA). We treated 14 patients (12 men, two women; mean age, 56.2 years) with ruptured VADAs between March 1999 and June 2012 at our hospital. Six and eight patients had Hunt and Hess grades 1-3 and 4-5, respectively. Twelve patients underwent internal endovascular trapping, one underwent proximal endovascular occlusion alone, and one underwent proximal endovascular occlusion in the acute stage and occipital artery (OA)-PICA anastomosis and surgical trapping in the chronic stage. The types of VADA based on their location relative to the ipsilateral PICA were distal, PICA-involved, and non-PICA in nine, two, and three patients, respectively. The types of PICA based on their development and location were bilateral anterior inferior cerebellar artery (AICA)-PICA, ipsilateral AICA-PICA, extradural, and intradural type in one, two, two, and nine patients, respectively. Two patients with high anatomical risk developed medullary infarction, but their midterm outcomes were better than in previous reports. The modified Rankin scale indicated grades 0-2, 3-5, and 6 in eight, three, and three patients, respectively. A good outcome is often obtained in the treatment of ruptured VADA using internal endovascular trapping, except in the PICA-involved type, even with high-grade subarachnoid hemorrhage. Treatment of the PICA-involved type is controversial. The anatomical location and development of PICA may be predicted by complications with postoperative medullary infarction. PMID:24976093

    On lifting a heavy case, a 51-year-old male experienced a sudden onset of headache with giddiness and clouded vision. A week later, vertigo and right hand numbness were added to his symptoms. The next day anisocoria (right > left) and dilation of the left retinal veins were noted. Cranial computed tomography (CT) scan appeared normal and there were no other remarkable neurological findings. The patient was treated conservatively for cerebral infarction, however, the headache worsened and diplopia occurred. Neurological examination on admission revealed nothing unusual except for left Horner's syndrome. Physical examination showed a palpable sausage-like painless tumor on the left side of the neck. Angiography showed a narrowing of the internal carotid artery in the cervical region with a small dissecting aneurysm at the C3 level. Cervical CT scan at the upper C3 level showed a low density lunar defect in the high density section of the enlarged left internal carotid artery. The patient was operated on by superficial temporal artery-middle cerebral artery anastomosis to increase the intracranial blood flow. Postoperatively the symptoms were quickly relieved. Angiography 1 month later showed less narrowing of the carotid artery, though the dissecting aneurysm still remained. Postoperative cervical CT scan showed the left internal carotid artery to be of normal size. The patient returned to his work in normal condition 2 months later. It is emphasized that cervical CT scan may be useful in the diagnosis of this unusual type of cervical dissecting aneurysm. (author)

    We report a patient with a probable dissecting aneurysm of the anterior inferior cerebellar artery (AICA) initially presenting with a nonhemorrhagic symptom, which resulted in subarachnoid hemorrhage. A 61-year-old woman suddenly experienced nausea. Computed tomography (CT) on admission showed a high-density mass with a double lumen in the right cerebellopontine angle without subarachnoid hemorrhage. Five days after the onset, she suddenly lost consciousness. CT demonstrated subarachnoid hemorrhage. Emergency angiography revealed a probable dissecting aneurysm at the lateral pontomedullary segment of the right AICA. Although the initial symptom is not hemorrhage, an unruptured dissecting aneurysm of the AICA may have a high risk of rupture. Immediate radical treatment to prevent subsequent rupture is necessary for even an unruptured dissecting aneurysm of the AICA. Copyright © 2015 National Stroke Association. Published by Elsevier Inc.

    Primary renal artery dissection is a rare condition that causes renal infarction and renovascular hypertension. We describe a case of a 48-year-old man who was admitted for left renal infarction due to a primary dissecting aneurysm of renal artery. He was diagnosed by a contrast enhanced abdominal CT scan and a renal angiography demonstrating a dissection at the branch of the left renal artery. He was treated with conservative medical management, including anticoagulation therapy. Forty-five primary renal artery dissections in 38 patients from previous reports were analyzed. Based on this analysis, many cases of primary renal artery dissection were male and had a high blood pressure. Primary renal artery dissection occurred at the right side (12 cases), left side (19), and bilaterally (7). The renal arterial branches were rarely involved in primary renal artery dissection. Assays of peripheral blood renin activity were performed in 15 patients, and all cases had a high value. Therefore, the present case is thought to be unique because he was a normotensive patient with normal plasma renin activity and the renal arterial branch was only dissected.

    Dissecting aneurysms of the vertebral artery (VA) are difficult to treat using current surgical and endovascular techniques. To analyze retrospectively the efficacy and safety of flow diverters in the treatment of dissecting aneurysms of the vertebral artery. We identified six patients with six unruptured VA dissecting aneurysms either arising from the V4 or V3-V4 junction that were treated with the Pipeline embolization device (PED) at our institution between July 2012 and February 2015. Among other parameters, technical feasibility of the procedure, procedure-related complications, angiographic results, and clinical outcome were evaluated. PED placement was achieved in all cases and immediate angiography follow-up demonstrated intra-aneurysmal contrast stasis with parent artery preservation. A temporary episode of dysarthria was noted in one patient. Major procedure-related complications were not observed. The 6-month follow-up (n=6) demonstrated complete/near-complete aneurysm obliteration in five patients and partial obliteration in one. At the 1-year follow-up (n=5) stable complete aneurysm occlusion was seen in two patients. Two cases showed progression from near complete occlusion and partial occlusion at 6 months to complete occlusion and near complete occlusion. One cases showed unchanged near complete occlusion. No aneurysmal bleeding, in-stent stenosis or thromboembolic complication was seen. National Institutes of Health Stroke Scale and modified Rankin scale scores remained unchanged from admission to discharge. Our preliminary experience with the use of PED for the treatment of intradural VA dissecting aneurysms shows promising short-term results, making this technique a feasible and safe treatment option in patients suitable for this approach. However, long-term and larger cohort studies are needed to validate these results. Published by the BMJ Publishing Group Limited.

    Isolated abducens nerve paresis related to ruptured vertebral artery (VA) aneurysm is rare. It usually occurs bilaterally or ipsilaterally to the pathologic lesions. We report the case of a contralateral sixth nerve palsy following ruptured dissecting VA aneurysm. A 38-year-old man was admitted for the evaluation of a 6-day history of headache. Abnormalities were not seen on initial computed tomography (CT). On admission, the patient was alert and no signs reflecting neurologic deficits were noted. Time of flight magnetic resonance angiography revealed a fusiform dilatation of the right VA involving origin of the posterior inferior cerebellar artery. The patient suddenly suffered from severe headache with diplopia the day before the scheduled cerebral angiography. Neurologic examination disclosed nuchal rigidity and isolated left abducens nerve palsy. Emergent CT scan showed high density in the basal and prepontine cistern compatible with ruptured aneurismal hemorrhage. Right vertebral angiography illustrated a right VA dissecting aneurysm with prominent displaced vertebrobasilar artery to inferiorly on left side. Double-stent placement was conducted for the treatment of ruptured dissecting VA aneurysm. No diffusion restriction signals were observed in follow-up magnetic resonance imaging of the brain stem. Eleven weeks later, full recovery of left sixth nerve palsy was documented photographically. In conclusion, isolated contralateral abducens nerve palsy associated with ruptured VA aneurysm may develop due to direct nerve compression by displaced verterobasilar artery triggered by primary thick clot in the prepontine cistern.

    Isolated dissecting aneurysms of the posterior cerebral artery are not as rare as previously reported. Affecting primarily a younger population, this condition can be recognized by angiographic patterns, the most common being a ''pearl and string'' morphology. We reviewed the literature and present a series of six cases, discussing management strategies. (orig.)

    Indocyanine green videoangiography (ICG-VA) is an important intraoperative adjunct for saccular aneurysm surgery, but its efficacy in surgery for dissecting aneurysms has rarely been reported. The authors describe the usefulness of preclipping ICG-VA in a rare case of a ruptured dissecting aneurysm located at the precommunicating (A1) segment of the anterior cerebral artery. A 52-year-old woman, with no history of connective tissue diseases or vascular disorders, presented with sudden headache and convulsion. The CT scan showed that the patient had subarachnoid hemorrhage. Angiography showed a dissecting aneurysm in the left A1 segment of the anterior cerebral artery. Thus, the patient underwent trapping of the dissecting aneurysm. ICG-VA was used as an intraoperative adjunct before and after clipping. The preclipping ICG-VA showed the heterogeneously bright dissecting aneurysm and branching arteries even in the presence of hematoma. Preclipping ICG-VA may enhance the advantage of direct surgery for dissecting aneurysm by allowing visualization of the extent of the dissected vascular wall and the related branching arteries. ICG-VA can be an indispensable adjunct to minimize the compromise from the surgical treatment for intracranial dissecting aneurysms. Copyright © 2017 by the Congress of Neurological Surgeons

    2015-01-01

    Full Text Available Background: The endovascular strategy of the huge dissecting aneurysms involving the basilar artery (BA is controversial and challenging. This study was to investigate the clinical and angiographic outcomes of the treatment of the huge dissecting aneurysms involving the BA by the internal trapping (IT technique. Methods: We retrospectively studied 15 patients with the huge dissecting aneurysms involving the BA treated by the IT technique between September 2005 and September 2014 in Department of Interventional Neuroradiology of Beijing Tiantan Hospital. Clinical and angiographic data were reviewed and evaluated. Results: All patients were treated by the IT technique. That meant the dissecting artery and aneurysm segments were completed occlusion. After the procedure, the angiography demonstrated that all the dissecting artery and aneurysm segments were completed occlusion. Follow-up angiography was performed at 3-6 months or 12-18 months after the endovascular treatment (median 8 months, 14 patients had a good recovery. Re-canalization occurred in one patient whose aneurysm involved in bilateral vertebral arteries and the two third of the middle-lower BA. After the second treatment, the patient died by the ventricular tachycardia. Conclusions: The IT technique is a technically feasible and safe alternative for the treatment of BA dissecting aneurysms, but it is not necessarily the safest or most definitive treatment modality. The ideal treatment of the huge dissecting aneurysms involving the BA remains debatable and must be investigated on a case-by-case basis.

    We report here a case of a patient with a dissecting aneurysm of the anterior medullary segment of the posterior inferior cerebellar artery (PICA) which presented with Wallenberg's syndrome. A 32-year-male presented with an unusual case of Wallenberg's syndrome due to a dissecting aneurysm of the PICA manifesting as a sensation of heaviness in the occipital region and vertigo. The occipital symptoms persisted and vertigo and vomiting developed after 6 days. Numbness developed on the left side of the patient's face, and hyperalgesia on the right side of the body. The diagnosis of Wallenberg's syndrome was based on the above findings. MRI revealed infarction of the lateral aspect of the medulla oblongata and MR angiography revealed dilatation in the proximal portion of the left PICA. Digital subtraction angiography revealed that the left vertebral artery was essentially normal, but there was a spindle-shaped dilatation in the proximal portion of the left PICA. We carried out conservative therapy at the patient's request and 3D-CTA revealed that the dissecting aneurysm was markedly reduced in size seven months after the onset. Dissecting aneurysms of the intracranial posterior circulation have been shown to be less uncommon than previously thought. However, those involving the PICA without involvement of the vertebral artery at all are extremely rare. The natural history of the dissecting PICA aneurysm was unknown, and the indication for surgical treatment of such aneurysms remains controversial. Management options are conservative treatment, open surgical treatment including wrapping, trapping, and resection with reconstruction, but almost all of the patients underwent radical treatment to prevent rupture of the aneurysm. However we had no knowledge of the risk of rupture of a PICA dissecting aneurysm presenting with ischemic symptoms. We have reviewed the well-documented 15 cases of dissecting aneurysms of the PICA reported in the literature and we discuss the

    Full Text Available The etiology of the vertebral dissecting aneurysms is largely unknown, and they frequently occurs in relatively healthy young men. Objectives and Methods. A series of 57 consecutive cases defined by angiography were evaluated with regard to deviation in the course of the affected and contralateral vertebral arteries. Division was into 3 types: Type I without any deviation, Type II with mild-to-moderate deviation but not over the midline; and Type III with marked deviation over to the contralateral side beyond the midline. Results. The most frequent type of VA running was Type III for the affected and Type I nonaffected side, with this being found in all 17 patients except one. All of the Type III dissections occurred just proximal to a tortuous portion, while in cases with Type-I- and Type-II-affected sides, the majority (33 of 39 occurred near the union of the vertebral artery. In 10 of 57, a non-dominant side was affected, all except one being of Type I or II. With 12 recent patients assessed angiographically in detail for hemodynamics, eleven patients showed contrast material retrograde inflowing into the pseudolumen from the distal portion of the dissection site. Turbulent blood flow was recognized in all of these patients with retrograde inflow. Conclusions. Turbulent blood flow is one etiology of vertebral artery dissection aneurysms, with the sites in the majority of the cases being just proximal to a tortuous portion or union of vessels. In cases with dissection proximal to the tortuous course of the vertebral artery, retrograde inflow will occur more frequently than antegrade, which should be taken into account in designing therapeutic strategies.

    Ruptured intracranial dissecting aneurysms must be secured quickly to prevent re-hemorrhage. Endovascular sacrifice of the diseased segment is a well-established treatment method, however postoperative outcomes of symptomatic stroke and re-hemorrhage rates are not well reported, particularly for the perforator-rich distal vertebral artery or proximal posterior inferior cerebellar artery (PICA). We retrospectively reviewed cases of ruptured distal vertebral artery or PICA dissecting aneurysms that underwent endovascular treatment. Diagnosis was based on the presence of subarachnoid hemorrhage on initial CT imaging and of a dissecting aneurysm on catheter angiography. Patients with vertebral artery aneurysms were selected for coil embolization of the diseased arterial segment based on the adequacy of flow to the basilar artery from the contralateral vertebral artery. Patients with PICA aneurysms were generally treated only if they were poor surgical candidates. Outcomes included symptomatic and asymptomatic procedure-related cerebral infarction, recurrent aneurysm rupture, angiographic aneurysm recurrence, and estimated modified Rankin Scale (mRS). During the study period, 12 patients with dissecting aneurysms involving the distal vertebral artery (n=10) or PICA (n=2) were treated with endovascular sacrifice. Two patients suffered an ischemic infarction, one of whom was symptomatic (8.3%). One patient (8.3%) died prior to hospital discharge. No aneurysm recurrence was identified on follow-up imaging. Ten patients (83%) made a good recovery (mRS ≤2). Median clinical and imaging follow-up periods were 41.7 months (range 0-126.4 months) and 14.3 months (range 0.03-88.6 months), respectively. In patients with good collateral circulation, endovascular sacrifice may be the preferred treatment for acutely ruptured dissecting aneurysms involving the distal vertebral artery.

    We report a rare case of a ruptured dissecting anterior inferior cerebellar artery (AICA) aneurysm treated by endosaccular embolization with a Guglielmi detachable coil (GDC). An 85-year-old female presented with headache. Computed tomographic (CT) scan showed subarachnoid hemorrhage and intraventricular hemorrhage in the fourth ventricule. Cerebral angiography and 3D-CT angiography revealed an aneurysmal dilatation at the anterior pontine segment of the right AICA with a diagnosis of arterial dissection. The right posterior inferior cerebellar artery (PICA) was absent and the right AICA supplied the territory normally nourished by the right PICA. The aneurismal dilatation was occluded by endosacullar embolization with preservation of the AICA. The distal AICA aneurysm is rare and only seven cases treated with endovascular embolization have been reported. In these, six cases were treated by parent artery occlusion with coil and the subsequent three cases presented with ischemic complications. Only one case was treated by endosaccular embolization with GDC. To our knowledge, this is the second report of the distal AICA aneurysm treated by endosaccular embolization with GDC. Distal AICA aneurysms are briefly discussed while reviewing the literature.

    Marfan syndrome is a connective tissue disorder associated with aortic dissection, aneurysmal degeneration and rupture. These cardiovascular complications represent the main cause of mortality, therefore repair is indicated. We present a 35-year-old woman who experienced acute onset of chest pain. Her imaging revealed a chronic DeBakey type I dissection with aortic root dilation and descending thoracic aneurysmal degeneration. She underwent a Bentall procedure and endovascular exclusion of the descending thoracic aortic aneurysm. She was closely followed and 2 years later a computed tomography angiography (CTA) revealed the aneurysmal degeneration of the thoracoabominal aorta and bilateral iliac arteries. The patient underwent a composite reconstruction using multi-visceral branched and bifurcated Dacron grafts. At 5 years from her last surgery, a CTA revealed no new dissection or further aneurysmal degenerations. Aortic disease in Marfan patients is a complex clinical problem that may lead to secondary or tertiary aortic reconstructions; close follow-up is mandatory.

    Full Text Available The retreatment of recurrent intracranial vertebral artery dissecting aneurysms (VADAs after stent assisted coiling (SAC has not yet been studied. The purpose of this study was to evaluate the strategies and outcomes for retreatment of recurrent VADAs after SAC.Between September 2009 and November 2013, six consecutive patients presenting with recurrent intracranial VADAs after SAC were enrolled in this study. They were all male with age ranging from 29 to 54 years (mean age, 46.2 years. The procedures of treatments and angiographic and clinical follow-up were reviewed retrospectively. Retreatment modalities were selected individually according to the characteristics of recurrence. The outcomes of retreatment were evaluated by angiographic and clinical follow-up.Six patients with recurrent intracranial VADAs after SAC were retreated, with second SAC in three patients, coil embolization, double overlapping stents placement and endovascular occlusion with aneurysm trapping in one patient, respectively. Immediate angiographic outcomes of retreatment were: complete occlusion in three patients, nearly complete occlusion in two patients, and contrast medium retention in dissecting aneurysm in one patient. All cases were technically successful. No complications related to endovascular procedures occurred. Angiographic follow-up was available in all five patients treated with second SAC or double overlapping stents, which was complete occlusion in four patients, obliteration of parent artery in one patient, showing no recurrence at 4-11 months (mean: 8.6 months. Clinical follow-up was performed in all six patients at 11-51 months after initial endovascular treatment and at 9-43 months after retreatment. The mRS of last clinical follow-up was excellent in five patients and mild disability in only one patient.Endovascular retreatment is feasible and effective for recurrent intracranial VADAs after SAC. Individualized strategies of retreatment should be

    Full Text Available The Low-profile Visualized Intraluminal Support (LVIS device is a new generation of self-expanding braided stent recently introduced in China for stent assisted coiling of intracranial aneurysms. The aim of our study is to evaluate the feasibility, safety, and efficacy of the LVIS device in reconstructive treatment of vertebral artery dissecting aneurysms (VADAs.We retrospectively reviewed the neurointerventional database of our institution from June 2014 to May 2016. Patients who underwent endovascular treatment of VADAs with LVIS stents were included in this study. Clinical presentation, aneurysmal characteristics, technical feasibility, procedural complications, and angiographic and clinical follow-up results were evaluated.38 patients with VADAs who underwent treatment with LVIS stent were identified, including 3 ruptured VADAs. All VADAs were successfully treated with reconstructive techniques including the stent-assisted coiling (n = 34 and stenting only (n = 4. Post-procedural complications developed in 3 patients (7.9% including two small brainstem infarctions and one delayed thromboembolic event. Complications resulted in one case of minor permanent morbidity (2.6%. There was no procedure-related mortality. The follow-up angiogram was available in 30 patients at an average of 8.3 months (range, 2 to 30 months, which revealed complete occlusion in 23 patients (76.7%, residual neck in five patients (16.7%, and residual sac in two patients (6.7%. The follow-up of 25 aneurysms with incomplete immediate occlusion revealed 22 aneurysms (88% with improvement in the Raymond class. One aneurysm (3.3% showed recanalization and required retreatment. Clinical followed-up at 5-28 months (mean 14.1 months was achieved in 36 patients because two patients died of pancreatic cancer and basal ganglia hemorrhage, respectively.

    Full Text Available Dyspepsia with mild, stabbing epigastric discomfort without history of trauma is a very common symptom that emergency physicians see in their daily practice. Vascular emergencies, mostly the aortic dissection and aneurysm, are always described in the differential diagnosis with persistent symptoms. Isolated celiac artery dissection occurring spontaneously is a very rare diagnosis. The involvement of branch vessels is generally observed and patients show various clinical signs and symptoms according to the involved branch vessel. Here we are presenting a case with spontaneous isolated celiac artery dissection, without any branch vessel involvement or visceral damage, detected by computed tomography scans taken on admission.

    Isolated saccular compared to fusiform aneurysm is considered to be a rare entity with challenges of its own. A 62-year-old female was diagnosed with a case of saccular aneurysm and penetrating atherosclerotic ulcer of the aortic arch. Additionally, she also had one vessel coronary artery disease and type B abdominal aortic dissection. She was then managed with open aortic arch repair and coronary artery bypass grafting. If required, elective endovascular repair will be done for the abdominal aorta on a later date.

    The hepatic artery aneurysms are rare, especially in interahepatic branches, The frequency consists of 75-80% extrahepatic and 20-25% intrahepatic. Catheterization is achieved usually from common femoral artery, other methods implemented in the case of unsuccessful catheterization from femoral artery, are translumbar and brachial catheterization. The study consist of 565 patients that were referred to the angiography ward, During seven years of assessment, five cases of hepatic artery aneurysm were found; this is a rare condition reported in the English literature. In the literature as well as in this case report the hepatic artery aneurysms are rare. In reported series the extrahepatic artery aneurysms are found more often than in the intrahepatic artery aneurysm but in this case report intrahepatic artery aneurysms are more than extrahepatic one.

Additionally, the effect of FDS on the aneurysmal flow pattern was investigated by performing in vivo flow analysis using parametric color coding (PCC). We evaluated 11 patients with unruptured, intradural VADAs, treated with FDS. Pre- and postinterventional DSA-series were postprocessed by PCC, and time-density curves were calculated. The parameters aneurysmal inflow-velocity, outflow-velocity and relative time-to-peak (rTTP) were calculated. Pre- and postinterventional values were compared and correlated with the occlusion rate after six months. Follow-up DSA detected 10 aneurysms occluded, meaning an occlusion rate of 91%. No procedure-related morbidity and mortality was found. Flow analyses revealed a significant reduction of aneurysmal inflow- velocity and prolongation of rTTP after FDS deployment. Concerning aneurysm occlusion, the postinterventional outflow-velocity turned out to be a marginally statistically significant predictor. A definite threshold value (-0.7 density change/s) could be determined for the outflow-velocity that allows prediction of complete aneurysm occlusion with high sensitivity and specificity (100%). Using FDS can be considered an efficient and safe therapy option in treating unruptured, intradural VADA. From in vivo flow analyses the postinterventional aneurysmal outflow-velocity turned out to be a potential predictor for later complete aneurysm occlusion. Here, it might be possible to determine a threshold value that allows prediction of aneurysm occlusion with high specificity and sensitivity. As fast, applicable and easy-to-handle tool, PCC could be used for procedural monitoring and might contribute to further treatment optimization. © The Author(s) 2015.

    Cine MRI was performed in 25 cases of aortic dissection and comparative study among cine MRI, spin-echo static MRI, contrast-enhanced CT and intravenous digital subtraction angiography (IVDSA) was made. Cine MRI accurately detected aortic dissection. It was most accurate among various diagnostic methods in demonstration of entry site of dissection. Take-off of renal artery and its relation to true and false channels was also accurately demonstrated by cine MRI. The above results suggest that cine MRI can be an important diagnostic modality with almost equal diagnostic quality to those of conventional angiography. However, further technical improvement to shorten the imaging time seems necessary to replace angiography. (author)

    Anterior choroid artery aneurysms (AChAAs) constitute 2%-5% of all intracranial aneurysms. They are usually small, thin walled with one or several arteries originating at their base, and often associated with multiple aneurysms. In this article, we review the practical microsurgical anatomy, the preoperative imaging, surgical planning, and the microneurosurgical steps in the dissection and the clipping of AChAAs. This review, and the whole series on intracranial aneurysms (IAs), are mainly based on the personal microneurosurgical experience of the senior author (J.H.) in two Finnish centers (Helsinki and Kuopio) that serve, without patient selection, the catchment area in Southern and Eastern Finland. These two centers have treated more than 10,000 patients with IAs since 1951. In the Kuopio Cerebral Aneurysm Database of 3005 patients with 4253 IAs, 831 patients (28%) had altogether 980 internal carotid artery (ICA) aneurysms, of whom 95 patients had 99 (2%) AChAAs. Ruptured AChAAs, found in 39 patients (41%), with median size of 6 mm (range = 2-19 mm), were associated with intracerebral hematoma (ICH) in only 1 (3%) patient. Multiple aneurysms were seen in 58 (61%) patients. The main difficulty in microneurosurgical management of AChAAs is to preserve flow in the anterior choroid artery originating at the base and often attached to the aneurysm dome. This necessitates perfect surgical strategy based on preoperative knowledge of 3 dimensional angioarchitecture and proper orientation during the microsurgical dissection.

    Splenic artery aneurysms - the most common visceral artery aneurysms - are found most often in multiparous women and in patients with portal hypertension. Indications for treatment of splenic artery aneurysm or pseudoaneurysm include specific symptoms, female gender and childbearing age, presence of portal hypertension, planned liver transplantation, a pseudoaneurysm of any size, and an aneurysm with a diameter of more than 2.5cm. Historically, the treatment of splenic artery aneurysm has been surgical ligation of the splenic artery, ligation of the aneurysm, or aneurysmectomy with or without splenectomy, depending on the aneurysm location. There are other percutaneous interventional techniques. The authors present a case of a splenic artery aneurysm in a 51-year-old woman, detected incidentally. RESUMO Aneurismas da artéria esplênica - os aneurismas arteriais viscerais mais comuns - são encontrados mais frequentemente em mulheres multíparas e em pacientes com hipertensão portal. As indicações para o seu tratamento incluem sintomas específicos, sexo feminino e idade fértil, presença de hipertensão portal, paciente em fila de transplante hepático, um pseudoaneurisma de qualquer tamanho, e um aneurisma com um diâmetro superior a 2,5cm. Historicamente, o tratamento do aneurisma da artéria esplênica tem sido a ligadura cirúrgica da artéria esplênica, a ligadura do aneurisma ou a aneurismectomia, com ou sem esplenectomia, dependendo do local do aneurisma. Existem outras técnicas intervencionistas percutâneas. Os autores apresentam o caso de um aneurisma de artéria esplênica em uma mulher de 51 anos de idade, diagnosticado incidentalmente.

    The authors describe the off-label use of Onyx for embolization of fusiform mycotic and dissecting intracranial aneurysms based on their experience with 3 patients treated at the University of Utah Hospital from 2006 through 2007. Technical success in occluding the parent artery/aneurysm was achieved in all patients. There were no complications. The authors conclude that Onyx can be used to achieve occlusion of fusiform mycotic and dissecting intracranial aneurysms in conjunction with parent artery occlusion.

    Intracranial aneurysms in the paediatric population are uncommon, accounting for 2% to 6% of all aneurysms, and spontaneous arterial dissection is rarely reported as the cause of aneurysms in children, especially in the posterior cerebral artery. Two cases of paediatric spontaneous posterior cerebral artery dissecting aneurysms are reported, one in a 33-month-old male child presenting with aneurysmal rupture and subarachnoid haemorrhage and the other in a 9-year-old boy with an unruptured aneurysm. The first child was successfully treated by endovascular parent vessel occlusion without neurological deficit and in the second a spontaneous thrombosis of the aneurysm and its parent artery occurred associated with hydrocephalus and a favourable outcome. Dissecting aneurysms are dynamic lesions with variable and unpredictable evolution and close follow-up and/or early treatment is warranted. Spontaneous arterial dissection is a rare, probably still under-recognized, cause of intracranial aneurysms that may be responsible for a significant number of aneurysms and spontaneous aneurysmal thromboses in children.

    Bilateral internal carotid artery dissections have been reported, but spontaneous bilateral dissections are rare. Internal carotid artery dissection can present with a spectrum of symptoms ranging from headache to completed stroke. Two cases of spontaneous bilateral carotid artery dissection are presented, one with headache and minimal symptoms and the other with a stroke syndrome. No cause could be found in either case, making the dissections completely spontaneous. Bilateral internal carotid artery dissection (ICAD) should be considered in young patients with unexplained head and neck pain with or without focal neurological symptoms and signs. The increasing availability of imaging would sustain the higher index of suspicion.

    2005-01-01

    Traumatic cervical artery dissection (TCAD) is a complication of severe blunt head or neck trauma, the main cause being motor vehicle accidents. TCAD are increasingly recognized, and incidences of up to 0.86% for internal carotid and 0.53% for traumatic vertebral artery dissections (TVAD) among blunt trauma victims are reported. Diagnostic evaluation for TCAD is mandatory in the presence of (1) hemorrhage of potential arterial origin originating from the nose, ears, mouth, or a wound; (2) expanding cervical hematoma; (3) cervical bruit in a patient >50 years of age; (4) evidence of acute infarct at brain imaging; (5) unexplained central or lateralizing neurological deficit or transient ischemic attack, or (6) Horner syndrome, neck or head pain. In addition, a number of centers screen asymptomatic patients with blunt trauma for TCAD. Catheter angiography is the standard of reference for diagnosis of TCAD. Color duplex ultrasound, computed tomographic, and magnetic resonance angiography are noninvasive screening alternatives, but each method has its diagnostic limitations compared to catheter angiography. Anticoagulants and antiplatelet drugs may prevent ischemic stroke, but bleeding from traumatized tissues may offset the benefits of antithrombotic treatment. Endovascular therapy of dissected vessels, thrombarterectomy, direct suture of intimal tears, and extracranial-intracranial bypass should be considered in exceptional cases. Neurological outcome is probably worse in TCAD compared to spontaneous CAD, although it is unclear whether this is due to dissection-induced ischemic stroke or associated traumatic lesions.

  19. Epidemiology of aortic disease - aneurysm, dissection, occlusion

    Steckmeier, B.

    2001-01-01

    The physiological infrarenal aortic diameter varies between 12.4 mm in women an 27.6 mm in men. As defined, an aneurysmatic dilatation begins with 29 mm. According to that, 9% of all people above the age of 65 are affected by an abdominal aortic aneurysm (AAA). Compared with the female sex, the male sex predominates at a rate of about 5:1. The disease is predominant in men of the white race. In black men, black and white women the incidence of AAA is identical. 38 to 50 percent of the AAA patients (patients) suffer from hypertension, 33 to 60% from coronary, 28% from cerebrovascular and 25% from peripheral occlusive disease. The AAA expansion rate varies between 0.2 and 0.8 cm per year and is exponential from a diameter of 5 cm on. In autopsy studies, the rupture rates with AAA diameters of 7 cm were below 5%, 39% and 65%, respecitvely. 70% of the AAA patients do not die of a rupture, but of a cardiac disease. Serum markers, such as metalloproteinases and procollagen peptides are significantly increased in AAA patients. Thoraco-abdominal aneurysms (TAA) make up only 2 to 5% of all degenerative aneurysms. 20 to 30% of the TAA patients are also affected by an AAA. 80% of the TAA are degenerative, 15 to 20% are a consequence of the chronic dissection - including 5% of Marfan patients -, 2% occur in case of infections and 1 to 2% in case of aortitis. The TAA incidence in 100,000 person-years is 5.9% during a monitoring period of 30 years. In case of TAA, an operation is indicated with a maximum diameter of 5.5 to 6 cm and more and, in case of a Marfan's syndrome (incidence of 1:10,000), with a maximum diameter of 5.5 cm and more. With regard to aorto-iliac occlusive diseases, there are defined 3 types of distribution. Type I refers to the region of the bifurcation itself. Type II defines the diffuse aortoiliac spread of the disease. Type III designates multiple-level occlusions also beyond the inguinal ligament. Type I patients in most cases are female and more

    Full Text Available Aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. The most common cause of coronary artery aneurysms is atherosclerosis. Angiography is the gold standard for diagnosis and treatment. Depending on the severity of the coexisting coronary stenosis, patients with left main coronary artery aneurysms can be effectively managed either surgically or pharmacologically. We herein report a case of left main coronary artery aneurysm in a 72-year-old man with a prior history of hypertension presenting to our hospital because of unstable angina. The electrocardiogram showed ST-segment depression and T-wave inversion in the precordial leads. All the data of blood chemistry were normal. Echocardiography showed akinetic anterior wall, septum, and apex, mild mitral regurgitation and ejection fraction of 45%. Coronary angiography revealed a saccular aneurysm of the left main coronary artery with significant stenosis in the left anterior descending, left circumflex, and right coronary artery. The patient immediately underwent coronary artery bypass grafting and ligation of the aneurysm. At six months’ follow-up, he remained asymptomatic.

    The magnetic resonance (MR) findings of three cases with vertebro-basilar dissecting aneurysms (DA) were compared with those of two cases with vertebro-basilar fusiform aneurysms (FA). No abnormal findings, excepting a dilatation of a signal-void area corresponding to the arterial blood flow, were shown on the MR images in the patients with a FA. In contrast to the FA cases, various abnormalities were detected by the MR studies in all three DA cases. An intimal flap and a double lumen were demonstrated in one case. An intra-mural hematoma was shown in one case. A hematoma neighboring the parent artery was demonstrated in two cases. MR imaging was thought to be useful for detecting intracranial vascular lesions, such as a DA, and for discriminating between a DA and a FA. (orig.)

    Full Text Available INTRODUCTION Renal artery aneurysms is relatively uncommon with reported incidence ranges from 0.3% to 1%. However, considering all visceral artery aneurysms the percentage of renal artery aneurysms is relatively high between 15-25%. The distal forms of renal artery aneurysms sometimes require "ex vivo" reconstruction and kidney autotransplantation. CASE REPORT A 75-year-old male presented with the right abdominal and back pain. He suffered from a long history of arterial hypertension and chronic renal failure over the last few months (urea blood = 19.8 mmol/l; creatinine = 198 mmol/l. Duplex ultrasonography showed abdominal aortic aneurysm. Subsequent translumbarangiography revealed juxtarenal abdominal aortic aneurysm associated with distal right renal artery aneurysm. The operation was performed under combined thoracic epidural analgesia and general anesthesia using transperitoneal approach. After the laparotomy, the ascending colon was mobilized and reflected medially followed by Kocher maneuver. The result was visualization of the anterior aspect of the right kidney, the collecting system, ureter as well as the right renal vein and artery with large saccular aneurysm located distally. After mobilization of the renal vessels and careful dissection of the ureter, the kidney was explanted. The operation was continued by two surgical teams. The first team performed abdominal aortic aneurysm resection and reconstruction with bifurcated Dacron graft. The second team performed ex vivo reparation of renal artery aneurysm. All time during the explantation, the kidney was perfused by Collins' solution. The saccular right renal artery aneurysm 4 cm in diameter was located at the kidney hilus at the first bifurcation. Three branches originated from the aneurysm. The aneurysm was resected completely. The longest and widest of three branches arising from the aneurysmal sac was end-to-end anastomized with 6 mm PTFE graft. After this intervention, one of

    Full Text Available Extracranial carotid artery aneurysms (ECAA are rare but may be accompanied with significant morbidity. Previous studies mostly focused on diagnostic imaging and treatment. In contrast, the pathophysiological mechanisms and natural course of ECAA are largely unknown. Understanding the pathophysiological background may add to prediction of risk for adverse outcome and need for surgical exclusion. The aim of this study was to investigate the histopathological characteristics of ECAA in patients who underwent complete surgical ECAA resection.From March 2004 till June 2013, 13 patients were treated with open ECAA repair. During surgery the aneurysm sac was resected and processed for standardized histological analysis. Sections were stained with routine hematoxylin and eosin and special stains to detect elastin, collagen, different types of inflammatory cells, vascular smooth muscle cells and endothelial cells.Histopathological characterization revealed two distinct categories: dissection (abrupt interruption of the media; n = 3 and degeneration (general loss of elastin fibers in the media; n = 10. In the degenerative samples the elastin fibers in the media were fragmented and were partly absent. Inflammatory cells were observed in the vessel wall of the aneurysms.Histological analysis in this small sample size revealed dissection and degeneration as the two distinct underlying mechanisms in ECAA formation.

    Middle cerebral artery (MCA) aneurysms usually arise at the primary MCA bifurcation or trifurcation. Distal MCA aneurysms are rarely considered as sources of aneurysmal subarachnoid hemorrhage (SAH). It has been reported that ruptured distal MCA aneurysms are associated with head trauma, neoplastic emboli, arterial dissection, or bacterial infection. We experienced five cases of ruptured distal MCA aneurysms and evaluated their clinical characteristics. Retrospective analysis of aneurysmal SAH at Kobayashi Neurosurgical Neurological Hospital was performed from January, 2004 to December, 2014. Clinical characteristics of ruptured distal MCA aneurysms were analyzed using our database. Among 191 aneurysmal SAH patients, there were five ruptured distal MCA aneurysms. All patients did not have any specific medical problems such as infectious disease, head trauma, or cardiac disorders. The incidence of ruptured distal MCA aneurysm was higher than expected and was equivalent to 9.4% of the total ruptured MCA aneurysms. Strong male predominance (80%) and M2-3 junction aneurysm preponderance (80%) were observed. In addition, there were only two patients (40%) with intracerebral hematoma in our study. We reported five cases of ruptured distal MCA aneurysms. Although ruptured distal MCA aneurysms are thought to be rare as sources of aneurysmal SAH, the incidence of ruptured distal MCA aneurysm was 9.4% of all ruptured MCA aneurysms in our study. Ruptured distal MCA aneurysms should be considered as sources of aneurysmal SAH without intracerebral hematoma. Copyright © 2017 Elsevier Ltd. All rights reserved.

  9. Giant Dissecting Aortic Aneurysm in an Asymptomatic Young Male

    2015-01-01

    Full Text Available Giant aortic aneurysm is defined as aneurysm in the aorta greater than 10 cm in diameter. It is a rare finding since most patients will present with complications of dissection or rupture before the size of aneurysm reaches that magnitude. Etiological factors include atherosclerosis, Marfan’s syndrome, giant cell arteritis, tuberculosis, syphilis, HIV-associated vasculitis, hereditary hemorrhagic telangiectasia, and medial agenesis. Once diagnosed, prompt surgical intervention is the treatment of choice. Although asymptomatic unruptured giant aortic aneurysm has been reported in the literature, there has not been any case of asymptomatic giant dissecting aortic aneurysm reported in the literature thus far. We report a case of giant dissecting ascending aortic aneurysm in an asymptomatic young male who was referred to our institution for abnormal findings on physical exam.

    OBJECTIVE While most paraclinoid aneurysms can be clipped with excellent results, new postoperative visual deficits are a concern. New technology, including flow diverters, has increased the popularity of endovascular therapy. However, endovascular treatment of paraclinoid aneurysms is not without procedural risks, is associated with higher rates of incomplete aneurysm occlusion and recurrence, and may not address optic nerve compression symptoms that surgical debulking can. The increasing endovascular management of paraclinoid aneurysms should be justified by comparisons to surgical benchmarks. The authors, therefore, undertook this study to define patient, visual, and aneurysm outcomes in the most common type of paraclinoid aneurysm: ophthalmic artery (OphA) aneurysms. METHODS Results from microsurgical clipping of 208 OphA aneurysms in 198 patients were retrospectively reviewed. Patient demographics, aneurysm morphology (size, calcification, etc.), clinical characteristics, and patient outcomes were recorded and analyzed. RESULTS Despite 20% of these aneurysms being large or giant in size, complete aneurysm occlusion was accomplished in 91% of 208 cases, with OphA patency preserved in 99.5%. The aneurysm recurrence rate was 3.1% and the retreatment rate was 0%. Good outcomes (modified Rankin Scale score 0-2) were observed in 96.2% of patients overall and in all 156 patients with unruptured aneurysms. New visual field defects (hemianopsia or quadrantanopsia) were observed in 8 patients (3.8%), decreased visual acuity in 5 (2.4%), and monocular blindness in 9 (4.3%). Vision improved in 9 (52.9%) of the 17 patients with preoperative visual deficits. CONCLUSIONS The most important risk associated with clipping OphA aneurysms is a new visual deficit. Meticulous microsurgical technique is necessary during anterior clinoidectomy, aneurysm dissection, and clip application to optimize visual outcomes, and aggressive medical management postoperatively might potentially

    Case 1: A 77-year-old woman had effort angina pectoris. Coronary angiography (CAG) revealed a coronary artery aneurysm on the left descending artery. Coronary artery bypass grafting (CABG) and patch angioplasty for the aneurysm were performed. Case 2 : A 69-year-old woman had effort dyspnea CAG showed dilation of the left main trunk and beaded aneurysms (maximum 6 cm in diameter) behind the ascending aorta with a fistula to the right atrium. We closed the fistula and performed CABG to the circumflex branch. Case 3 : A 78-year-old woman had had general fatigue for 2 weeks. Previous CAG had revealed coronary artery aneurysms and current chest computered tomography revealed pericardial effusion. She was, therefore, diagnosed with the rupture of the coronary artery aneurysm. We closed the coronary artery aneurysm and performed CABG. Case 4: A 55-year-old man had been diagnosed with acute myocardial infarction and had undergone percutaneous coronary intervention 3 years before. CAG revealed a coronary artery aneurysm on the right coronary artery. We resected the aneurysm and interposed with saphenous vein graft. Although coronary artery aneurysm often has no symptoms, in the cases of angina, myocardial infarction, rupture or large aneurysm more than 3 times larger than the normal diameter, surgical repair should be considered.

    Dilation of the ascending aorta and aortic dissections are often seen in Marfan syndrome; however, true aneurysms of the subclavian and axillary arteries rarely seem to develop in patients who have this disease. We present the case of a 58-year-old man with Marfan syndrome who had undergone a Bentall procedure and thoracoabdominal aortic repair for an aortic dissection and who later developed multiple aneurysmal dilations of his right subclavian and axillary arteries. The aneurysms were succe...

  14. Ruptured gastroepiploic artery aneurysm: A case report

    Ahmad S. Ashrafi

    Full Text Available Introduction: Gastroepiploic artery aneurysms are extremely rare, with few reported cases in the literature. The risk of rupture however, is high and thus warrants attention. Presentation of case: Here we present a rare case of a women who presented to the emergency department in shock and was found to have a ruptured gastroepiploic artery aneurysm during surgical exploration. Suture ligation of the aneurysm was completed. Discussion: Although rare, gastroepiploic artery aneurysms have up to a 90% rate of rupture and therefore require intervention. A laparoscopic approach has been described however, in cases where rupture has occurred, urgent laparotomy and control of hemorrhage is needed. Conclusion: We describe a rare case of a ruptured gastroepiploic aneurysm that was successfully managed with urgent laparotomy and aneurysmal resection.

    2016-01-01

    Full Text Available We would like to describe a case with a complex aortic disease treated in hybrid fashion. We present an interesting case of a 65-year-old man with a medical history of hypertension, hyperlipidemia, and coronary artery disease percutaneously treated. An acute Type B aortic dissection occurred and treated with the implantation of a stent-graft which occluded the left subclavian artery due to its extension to the aortic arch. This event required a carotid-subclavian artery bypass due to ischemia of the left arm. An aneurysm in the innominate artery also detected, was treated with another stent-graft implantation 3 months later. At 5-year follow-up, an aneurysm of the thyreocervical trunk was found while the stent-graft of the aorta was well-tolerated without endoleak and the carotid-subclavian graft was patent. The aneurysm was asymptomatic but considering the risk of spontaneous rupture of an aneurysm of this size, elective surgery was indicated. Because the aneurysm was very close to the brachiocephalic bifurcation, open surgical repair would require a sternotomy. The right common carotid artery and right subclavian artery were exposed. The thyrocervical trunk, right internal mammary artery and right vertebral artery were occluded by ligations to isolate the aneurysm. An 8-mm Dacron graft was anastomosed end-to-end to the distal part of subclavian artery. We would like through this case, discuss the role of the hybrid cardiovascular surgery to minimize the postoperative complications in complex cardiovascular pathology. We also discuss the international bibliography about the thyreocervical trunk aneurysm and the treatment options.

    Pulmonary artery aneurysms are rare lesions. Clagett et al reported that one aneurysm of the pulmonary artery may be found in approximately 14,000 necropsies. We have experienced a case of giant pulmonary artery aneurysm confirmed by computed tomography. A 38 year-old man with atrial septal defect admitted to Kanazawa City Hospital. He had been pointed out of a right hilar mass when he was 26 years old. His complaint was bloody sputum and cough. Pulmonary angiography was not useful for the definite diagnosis because of its mural thrombi. Enhanced computed tomography showed a giant pulmonary artery aneurysm with a mural thrombi in its cavity. This shows that enhanced computed tomography is very useful for the diagnosis of a pulmonary artery aneurysm with a mural thrombi in its cavity. (author)

    Full Text Available Background:The creation of an electronic database facilitates the storage of information, as well as streamlines the exchange of data, making easier the exchange of knowledge for future research.Objective:To construct an electronic database containing comprehensive and up-to-date clinical and surgical data on the most common arterial aneurysms, to help advance scientific research.Methods:The most important specialist textbooks and articles found in journals and on internet databases were reviewed in order to define the basic structure of the protocol. Data were computerized using the SINPE© system for integrated electronic protocols and tested in a pilot study.Results:The data entered onto the system was first used to create a Master protocol, organized into a structure of top-level directories covering a large proportion of the content on vascular diseases as follows: patient history; physical examination; supplementary tests and examinations; diagnosis; treatment; and clinical course. By selecting items from the Master protocol, Specific protocols were then created for the 22 arterial sites most often involved by aneurysms. The program provides a method for collection of data on patients including clinical characteristics (patient history and physical examination, supplementary tests and examinations, treatments received and follow-up care after treatment. Any information of interest on these patients that is contained in the protocol can then be used to query the database and select data for studies.Conclusions:It proved possible to construct a database of clinical and surgical data on the arterial aneurysms of greatest interest and, by adapting the data to specific software, the database was integrated into the SINPE© system, thereby providing a standardized method for collection of data on these patients and tools for retrieving this information in an organized manner for use in scientific studies.

    1997-01-01

    To establish the method of constructing an experimental aneurysm model in porcine carotid artery Fourteen aneurysms were created in the carotid arteries of eight pigs. After paramedian incision under intravenous anesthesia, the common carotid artery and external jugular vein were separated. A portion of the latter was cut to make an aneurysmal sac and this was sutured to the side wall of the common carotid arterial wall (end to side). Within one week, anarteriogram was obtained in all pigs and color Doppler study was performed in four. Digital subtraction arteriograms were serially obtained three images/sec, and these were analyzed to determine the size of the sac and the neck, flow pattern in the aneurysm, and stenosis in the common carotid artery. Arteriographic findings were obtained in ten of 14 aneurysms. Six aneurysms were saccular in shape, and the mean size of the sac and neck was 16 x 10mm and 5.3mm, respectively. Four aneurysms were lobulated, and in these cases, the mean size of the sac and neck was 9 x 3mm and 3.7mm, respectively. The mean size of the proximal common carotid artery was 4.5mm, and at the operation site, mean stenosis was 40%. In 10/14 cases (71%), we successfully established an aneurysm model in the porcine carotid artery, and believe that it is suitable for use in interventional neuroradiology experiments

    Classification of paraclinoid carotid artery (CA) aneurysms based on their associated branching arteries has been confusing because superior hypophyseal arteries (SHAs) are too fine to appear opacified on cerebral angiograms. The authors performed a retrospective radiometric analysis of surgically treated paraclinoid aneurysms to elucidate their angiographic and anatomical characteristics. A retrospective analysis was made of 85 intradural paraclinoid aneurysms in which the presence or absence of branching arteries had been determined at the time of surgical clipping. The lesions were classified as supraclinoid, clinoid, and infraclinoid aneurysms based on their relation to the anterior clinoid process on lateral angiograms of the CA. The direction of the aneurysms were measured according to angles formed between the medial portion of the horizontal line crossing the aneurysm sac and the center of the aneurysm neck on anteroposterior angiograms. Branching arteries were associated with 68 aneurysms, of which 28 were ophthalmic artery (OphA) lesions (32.9%) and 40 were SHA ones (47.1%); associated branching arteries were absent in 17 aneurysms (20%). Twenty-five aneurysms (29.4%) were located at the supraclinoidal level, 46 (54.1%) at the clinoidal, and 14 (16.5%) at the infraclinoidal. The majority of aneurysms identified at the supraclinoidal level were OphA lesions (44%) or those unassociated with branching arteries (48%), with mean directions of 57 degrees or 67 degrees, respectively. At the clinoidal level, the mean directions of aneurysms were 76 degrees in six lesions unassociated with branching arteries (13%), 43 degrees in 16 OphA lesions (35%), and -11 degrees in 24 SHA ones (52%). All aneurysms at the infraclinoidal level arose at the origin of the SHAs, with a mean direction of -29 degrees, and most of these were embedded in the carotid cave. Aneurysms arising from the SHA can be distinguished from those not located at an arterial division by cerebral

    Intracranial vertebral artery (VA) dissection has three clinical presentations: ischemia, hemorrhage, and mass effect. Imaging findings of intracranial VA dissections vary according to clinical presentation. Irregular stenosis or occlusion of the VA is the most common finding in patients with posterior fossa infarction, whereas a dissecting aneurysm is the main feature in those with acute subarachnoid hemorrhage. A chronic, giant, dissecting aneurysm can cause mass effect on the brain stem or cranial nerves, as well as distal embolism. Magnetic resonance imaging is useful for detection of intramural hematomas and intimal flaps, both of which are diagnostic of VA dissection. Multidetector computed tomography angiography is increasingly used for diagnosis of VA dissection. Catheter angiography is still beneficial for evaluation of precise endoluminal morphology of the dissection before surgical or endovascular intervention. Endovascular treatment is now considered a major therapeutic option for patients with a ruptured dissecting aneurysm or a chronic dissecting aneurysm. Anticoagulation therapy is currently considered the initial treatment of choice in patients with posterior circulation ischemic symptoms. Endovascular treatment, such as stent-assisted angioplasty or coil occlusion at the dissection site, can be performed in selected patients with posterior fossa ischemic symptoms. (orig.)

    An isolated iliac artery aneurysm is where there is aneurysmal dilatation of one or more branches of the iliac system, with no associated dilatation of the aorta. Such aneurysms are rare and comprise 1% of all intra-abdominal aneurysms. The signs and symptoms of such an aneurysm are influenced by its concealed location within the bony pelvis. Awareness of these special characteristics improves the chances of early diagnosis and proper treatment before possible rupture. We present the clinical and radiological features of three such aneurysms. Ultrasound was the first imaging modality to be performed. Ipsilateral hydronephrosis was demonstrated in each case, this lead to imaging the pelvis and the correct diagnosis. We review the clinical and radiological literature and conclude that the pelvis should be imaged in all cases of unexplained hydronephrosis.

    Spontaneous isolated celiac artery dissection is a rare disease and patients without evidence of significant complications often resolve with medical therapy alone; however, the extension of the dissection can lead to more serious complications including aneurysmal dilatation, complete occlusion, and rupture of a visceral artery. In these patients, optimal management has not yet been clearly defined and treatment primarily depends on clinical presentation and lesions identified on imaging studies. This case report demonstrates the conservative management of spontaneous celiac artery dissection. A 49-year-old male presented to our emergency department with acute and persistent abdominal pain. A contrast-enhanced computed tomogram (CT) of abdomen showed a pseudoaneurysm involving the ostium of the celiac artery with focal dissection, with no evidence of thrombosis or infarction to the visceral organs. Ultrasound studies demonstrated a prominent but patent celiac artery with adequate distal perfusion. Therefore, conservative medical management with antiplatelet therapy was initiated in our patient. Follow-up repeat ultrasound three weeks following discharge showed no evidence of dissection flap, stenosis, thrombosis or increase in the size of the aneurysm. This case report demonstrates that conservative medical management with antiplatelet therapy can be sufficient in treating spontaneous isolated celiac artery dissection with pseudoaneurysm formation. We suggest endovascular or surgical intervention should be reserved for patients who present with hemodynamic instability, or other serious complications, such as aneurysm rupture or visceral infarction.

    Endovascular treatment is an attractive approach for the treatment of unruptured vertebral dissecting aneurysms, and includes internal trapping and stent-assisted coil embolization. However, the optimal therapy remains debatable. We reviewed our experience with both endovascular treatment modalities and compared the safety, efficacy, and short-term outcomes for each approach. We retrospectively reviewed 65 consecutive patients with unruptured vertebral dissecting aneurysms who underwent endovascular treatment between January 2003 and January 2014. 24 patients underwent endovascular internal trapping (group A) while 41 patients underwent stent-assisted coiling (group B). Thirteen patients underwent single stent with coiling while 28 patients underwent double or three stent-assisted coiling. Short-term outcomes were evaluated using the modified Rankin Scale. A favorable clinical outcome was achieved in 58 of 65 patients. Procedure-related complications included ischemic symptoms (n = 6) and recurrence (n = 4). There was no statistical difference in modified Rankin Scale scoring between groups. Group A patients had more ischemia symptoms compared with group B patients (p = 0.043), Group B patients had higher recurrence rates compared with group A patients, but the difference had no statistical significance (p = 1.00). However, recurrence only occurred in patients who underwent stent-assisted coiling alone (p = 0.046). Stent-assisted coiling for unruptured vertebral dissecting aneurysms may maintain artery patency. Multilayer disposition of stents with coils may decrease complications and facilitate aneurysm occlusion. Larger, prospective studies are necessary to determine the long-term outcomes of reconstructive therapy.

  16. Self-limiting Spontaneous Isolated Celiac Artery Dissection: A Case Report

    Directory of Open Access Journals (Sweden)

    A.D. Morzycki

    Full Text Available : Introduction: Isolated dissection of the celiac artery is rare, with less then 100 cases reported to date. Although some patients present with epigastric pain and tenderness, many cases are asymptomatic and found incidentally on CT. The appropriate management of isolated celiac artery dissections is unclear. This report illustrates an observational approach to a symptomatic case of isolated celiac artery dissection. Report: A 55-year-old Caucassian male presented to the emergency department with epigastric pain. His Initial CT revealed possible celiac artery dissection with associated intramural hematoma. Due to continued pain, a subsequent CTA was ordered. This scan showed progression of the intramural hematoma to near occlusion of the hepatic artery. Despite this, there were no signs of ischemic hepatitis as indicated by normal levels of liver transaminases. There was also no evidence to suggest propagation of the dissection or pseudo-aneurysm formation. We therefore choose a conservative and observational approach to this isolated celiac artery dissection. His dissection was managed with ASA and metoprolol, and he was discharged after 1 week of observation. 3 week follow-up CTA showed spontaneous resolution of the intramural hematoma and improved patency of the hepatic artery. There was no change at 3 months follow-up. Conclusion: This case highlights that an observational approach to cases of isolated celiac artery dissection may be indicated if there is no evident end organ disease or malperfusion.

    1999-01-01

    Acute dissection of the thoracic aorta is a well-recognized, often fatal condition that frequently extends to involve the abdominal aorta and iliac vessels. The ostia of the renal and mesenteric vessels may be compromised, and the resulting visceral ischemia may necessitate surgical intervention. However, visceral perfusion may be restored if blood flow from true to false lumen is re-established or if the false lumen is obliterated, either spontaneously or by surgical or interventional techniques. Isolated dissections of mesenteric, renal, and carotid vessels are rarely reported. These may be spontaneous, related to high blood pressure and underlying disease of the vessel wall, or caused by abdominal trauma or medical intervention, including angiographic procedures. They are usually associated with pain and other signs and symptoms of ischemia in the appropriate territory. We present a case of chronic superior mesenteric artery (SMA) dissection, an incidental angiographic finding, in an asymptomatic patient being evaluated for resection of an abdominal aortic aneurysm (AAA).

    Full Text Available ABSTRACTBackground and Purpose: The pathogenesis of spontaneous cervical artery dissections (sCAD and its best medical treatment are debated. This may be due to a lack of clear classification of sCAD. We propose the new Borgess classification of sCAD, based on the presence or absence of intimal tear as depicted on imaging studies and effect on blood flow. Materials and Methods: This is a single-center investigator-initiated registry on consecutive patients treated for sCAD. In the Borgess classification, type I dissections have intact intima and type II dissections have an intimal tear. Results: Forty-four patients and 52 dissected arteries were found. Forty-nine of 52 dissections (93% were treated with dual anti-platelet therapy. Twenty-one of 52 dissections were type I; 31 were type II. Type I dissections were more likely to present with ischemic symptoms (stroke, TIA (p=0.001. More type I dissections occurred in the vertebral artery, while more type II dissections occurred in the internal carotid artery (p

    We present the case of a 65-year-old male who presented with stable angina and dyspnea on exertion. His initial workup yielded a positive treadmill stress test for reversible apical ischemia, and transthoracic echocardiogram demonstrated impaired systolic function. Cardiac catheterization was then performed, revealing severe atherosclerotic disease including multiple coronary artery aneurysms. As a result, the patient was advised to and subsequently underwent a coronary artery bypass graft. This case highlights the presence of multiple coronary artery aneurysms and the ability to appreciate these pathologic findings on multiple imaging modalities, including coronary angiogram, transesophageal echocardiography, and direct visualization through the surgical field.

    Because it is a very rare isolated lesion, we decided to present this case of idiopathic pulmonary artery aneurysm (IPAA) and review the cases published in the literature in order to correlate our clinical and imaging findings, as well as management based on patient data. IPAA was first described in a case of autopsy by Bristowe in 1860 and later in 1947 by Deterling and Claggett, whose prevalence was lower than eight to one hundred thousand. Although the use of diagnostic imaging methods has been applied in a very large population in recent decades, this lesion has been most often described in postmortem examinations. Therefore, it is important to be aware of possible clinical symptoms, at times non-specific, as well as the signs on imaging studies. In this study, therefore, the report of a case of an asymptomatic patient whose diagnosis was done through color Doppler echocardiography in a routine test in 2012, later confirmed by simple chest computed tomography (chest CT) and cardiac catheterization as IPAA and its branches. We discussed the literature available and the possibilities for treatment and the use of color Doppler echocardiography as an initial diagnostic tool for such a rare and intriguing disease. (author)

    Patients with aneurysmal dissections involving both the thoracic and the abdominal aorta are particularly challenging to treat with endovascular techniques because of the natural communications at the level of the visceral arteries. We present the case of a patient with Marfan syndrome with an aneurysmal aortic dissection involving the thoracic and abdominal aorta who was treated by a combination of endografts, surgical bypass, and a fenestrated tube graft.

    BACKGROUND: Cervical artery dissection is a common cause of stroke in young patients without vascular risk factors and may affect the carotid or vertebral arteries. The risk of spontaneous dissection is higher in those with genetic predisposing factors while other cases may be precipitated by an event involving head or neck movement or associated with direct neck trauma. CASE REPORT: We present the case of a previously well young woman with a history of migraine who developed internal carotid artery dissection following a turbulent short-haul commercial flight while restrained using a seatbelt. DISCUSSION: We propose that repetitive flexion-hyperextension neck movements encountered during the flight were the most likely precipitant of carotid artery dissection in this case and review the therapeutic options available.

    Full Text Available Spontaneous coronary artery dissection (SCAD is a very rare clinical condition. Physiopathology of SCAD is still mostly unclear. Clinical presentation of SCAD ranges from atypical symptoms to sudden cardiac death. The diagnosis of dissection is generally made by using conventional coronary angiography. Invasive or conservative treatment is reasonable.

    We evaluated the indications of operation and radiologic findings in 12 operated DeBakey type III aortic dissections. We retrospectively reviewed radiologic findings of 12 operated DeBakey type III aortic dissections, using CT, MRI, or aortography, and correlations were made with clinical course of the patients. Three cases were uncomplicated dissections. There were aneurysm rupture in 4 cases, impending rupture in 4 cases, occlusion of common iliac artery in 2 cases, occlusion of renal artery in 1 case, and compression of bronchus and esophagus by dilated aorta in 1 case. Associated clinical sign and symptoms were chest and back pain in 12 cases, claudication in 3 cases, dyspnea and dysphagia in 1 case, hoarseness in 1 case, and hemoptysis in 1 case. Post-operative complications were death from aneurysm rupture in 1 case, paraplegia in 2 cases, acute renal failure in 3 cases, and hemopericardium in 1 case. Although medical therapy is preferred in management of DeBakey type III aortic dissection, surgical treatment should be considered in patients with radiological findings of aortic rupture, impending rupture, occlusion of aortic major branches

    Purpose: True pancreaticoduodenal artery aneurysms are rare. No definitive study evaluating the natural history of these lesions or their preferred method of treatment has been published. The purpose of this study was to evaluate the outcome of preventive treatment of unruptured pancreaticoduodenal artery aneurysms using a Markov model. Materials and methods: With the use of a Markov model, we performed a decision analysis to evaluate the outcome of preventive treatment of unruptured pancreaticoduodenal artery aneurysms. The risk of rupture and the mortality of preventive treatment are unknown. Therefore, we performed sensitivity analysis using these parameters. Effectiveness was measured in life expectancy. Results: For 80-year-old patients, preventive treatment was dominated by no treatment if mortality rates of preventive treatment were greater than 1.4%, greater than 2.6%, greater than 3.8%, and greater than 4.8% at annual rupture rates of 1%, 2%, 3%, and 4%, respectively. For 50-year-old patients, preventive treatment was dominated by no treatment if mortality rates of preventive treatment were greater than 3.3%, greater than 5.9%, greater than 8.0%, and greater than 9.7% at annual rupture rates of 1%, 2%, 3%, and 4%, respectively. Conclusion: The effectiveness of preventive treatment of unruptured pancreaticoduodenal artery aneurysms depends on the aneurysm rupture rate, mortality rate of preventive treatment, and patient age. Taking into account the effects of these parameters is important in making treatment decisions.

    The pathogenesis of intracranial arterial aneurysms (AA) remains unclear, despite their clinical importance. An improved understanding of this disease is important in choosing therapeutic options. In addition to the ''classical'' berry-type aneurysm, there are various other types of intracranial AA such as infectious, dissecting or giant, partially-thrombosed aneurysms. From the clinician's perspective, the hypothesis that some of these intracranial AA might be due to abluminal factors has been proposed for several years. Indeed, this hypothesis and the empirical use of anti-inflammatory drugs in giant intracranial aneurysms have been confirmed by recent studies reporting that an enzyme involved in the inflammatory cascade (5-lipoxygenase or 5-LO) promotes the pathogenesis of specific aneurysms in humans. 5-LO generates different forms of leukotrienes which are potent mediators of inflammation. Adventitial inflammation leads to a weakening of the media from the abluminal part of the vessel wall due to the release of proinflammatory factors that invade the media, thereby degrading the extracellular matrix, the elastic lamina of the vascular wall, and, finally, the integrity of the vessel lumen. This in turn results in a dilation of the vessel and aneurysm formation. Moreover, neoangiogenesis of vasa vasorum is found in close proximity to 5-LO activated macrophages. In addition to this biological cascade, we argue that repeated subadventitial haemorrhages from the new vasa vasorum play an important role in aneurysm pathogenesis, due to a progressive increase in size mediated by the apposition of new layers of intramural haematoma within the vessel wall. Intracranial giant AA can therefore be regarded as a proliferative disease of the vessel wall induced by extravascular activity. (orig.)

    Isolated and spontaneous dissection of mesenteric arteries is a rare entity; a little more than 50 cases have been reported in medical literature. There is no therapeutic consensus concerning this type of lesion. In this study, we report the results of our treatment based on a conservative approach. This retrospective study concerns eight patients with dissection of the celiac trunk and/or of the upper mesenteric artery (UMA) who were treated between 2002 and 2006. Because these patients were not presenting with acute intestinal ischemia diagnosed by clinical examination or paraclinical tests (medical imaging/biology) or with vital complications, they were treated with an efficient anticoagulation (heparin followed by anti-vitamin K) for 3 to 6 months. Endovascular or surgical treatment was used as the first option in patients with obvious intestinal ischemia or likely to have an arterial rupture, and also when medical treatment had failed. Clinical and radiological follow-up was at 1 month, 3 months, 6 months, and 1 year and then every year. Seven men and one woman (mean age, 48.2; age range, 38-53 years) were treated. Six patients presented with isolated dissection (celiac trunk=4, UMA=2). One patient had a celiac trunk and a UMA dissection and one had a celiac trunk and a UMA dissection along with a dissection of his two renal arteries. On entering the hospital, a patient was operated on for mesenteric ischemia related to a stenosis of the upper mesenteric artery (upper aortomesenteric bypass); a covered stent was implanted in the celiac trunk of another patient presenting with a contained rupture. Both patients were successfully treated. Six patients were medically treated. One of them required an aortohepatic bypass to treat an aneurysmal evolution of the celiac trunk revealed by a computed tomography scan obtained 1 month after the symptoms had begun. In one patient, the dissection remained stable on imaging. Four patients were cured, with a mean 20.1-month

    Objective: To evaluate the clinical value of multiple detector computed tomography (MDCT) in the diagnosis and planning the treatment of splenic aneurysms. Methods: Eight cases with splenic artery aneurysms (SAA) were retrospectively reviewed. Sixty four-slice spiral CT scans were performed. Intravenous contrast material was injected at 4 ml/s, and arterial and venous phase images were obtained. Subsequently, arterial phase images were analyzed and made for CT angiography. The diagnosis was made by using axial and reconstructive images. All of the patients were also performed Doppler color echocardiography. Results: All patients showed splenic artery and splenic artery aneurysms clearly with CT arterial phase images. Among them, six patients had splenic artery aneurysms, one had giant splenic artery aneurysms (GSAA) and one had splenic artery pseudoaneurysms. Ultrasound examination only diagnosed six of them. Conclusion: MDCT is a noninvasive and valuable method in diagnosis of splenic artery aneurysms and has high value in determination of treatment plan

    Full Text Available Abstract Coronary artery dissection is a rare but well-described cause for myocardial infarction during the post-partum period. Dissection of multiple coronary arteries is even less frequent. Here we present a case of recurrent post-partum coronary artery dissections. This unusual presentation poses unique problems for management. A 35 year-old female, gravida 3 para 2, presented with myocardial infarction 9 weeks and 3 days post-partum. Cardiac catheterization demonstrated left anterior descending (LAD dissection but an otherwise normal coronary anatomy. The lesion was treated with four everolimus eluting stents. Initially the patient made an unremarkable recovery until ventricular fibrillation arrest occurred on the following day. Unsynchronized cardioversion restored a normal sinus rhythm and repeat catheterization revealed new right coronary artery (RCA dissection. A wire was passed distally, but it was unclear whether this was through the true or false lumen and no stents could be placed. However, improvement of distal RCA perfusion was noted on angiogram. Despite failure of interventional therapy the patient was therefore treated conservatively. Early operation after myocardial infarction has a significantly elevated risk of mortality and the initial dissection had occurred within 24 hours. This strategy proved successful as follow-up transthoracic echocardiography after four months demonstrated a preserved left ventricular ejection fraction of 55-60% without regional wall motion abnormalities. The patient remained asymptomatic from a cardiac point of view.

    Full Text Available Abstract Introduction Hepatic artery aneurysms remain a clinically significant entity. Their incidence continues to rise slowly and mortality from spontaneous rupture is high. Repair is recommended in those aneurysms greater than 2 cm in diameter. It is not surprising that vascular comorbidities, such as ischaemic heart disease, are common in surgical patients, particularly those with arterial aneurysms such as these. The decision of when to operate on patients who require urgent surgery despite having recently suffered an acute coronary syndrome remains somewhat of a grey and controversial area. We discuss the role of delayed surgery and postoperative followup of this vascular problem. Case presentation A 58-year-old man was admitted with a 5.5 cm hepatic artery aneurysm. The aneurysm was asymptomatic and was an incidental finding as a result of an abdominal computed tomography scan to investigate an episode of haemoptysis (Figure 1. Three weeks prior to admission, the patient had suffered a large inferior myocardial infarction and was treated by thrombolysis and primary coronary angioplasty. Angiographic assessment revealed a large aneurysm of the common hepatic artery involving the origins of the hepatic, gastroduodenal, left and right gastric arteries and the splenic artery (Figures 2 and 3. Endovascular treatment was not considered feasible and immediate surgery was too high-risk in the early post-infarction period. Therefore, surgery was delayed for 3 months when aneurysm repair with reconstruction of the hepatic artery was successfully performed. Graft patency was confirmed with the aid of an abdominal arterial duplex. Plasma levels of conventional liver function enzymes and of alpha-glutathione-S-transferase were within normal limits. This was used to assess the extent of any hepatocellular damage perioperatively. The patient made a good recovery and was well at his routine outpatient check-ups. Conclusion There is no significant

    Peripheral arterial aneurysms (PAA) may rupture, cause emboli and ischemia, and local symptoms due to compression. A total of 109 patients who underwent surgery for PAA were analyzed retrospectively, including clinical presentation, surgical procedures used, and postoperative follow-up data obtained 10 days after discharge. True aneurysm was present in 59 (54.1%) patients and pseudoaneurysm in 50 (45.9%). The femoral artery was the most common location. The surgical procedures used were as follows: graft interposition in 31 patients, bypass with synthetic or autologous grafts in 33 patients, aneurysm ligation in 5 patients, primary repair in 41 patients, and patch angioplasty reconstruction in 7 patients. One patient died as a result of massive hemorrhage. In four patients, amputation had to be performed. It is possible to prevent amputation and other complications, including mortality, during the surgical treatment of symptomatic and asymptomatic PAA.

    A 65-year-old female was admitted to our hospital complaining of left upper abdominal pain. Although the symptom improved with observation, serum creatinine rose to 2.0 mg/dl. Slight atrophy of the left kidney was seen on abdominal plain computed tomography. In order to examine the possibility of renal infarction from thrombosis with angiography, we consulted the department of cardiovascular medicine. Even though we did not detect thrombosis with left renal angiography or intravascular ultrasound, there was a dissection finding localized at the left renal artery. Based on this finding, we made a diagnosis of spontaneous renal artery dissection and performed stent placement. Spontaneous renal artery dissection is extremely rare and the frequency of occurrence is reported to be less than 0.05%. Recently, however the frequency of detection has risen with the development of clinical imaging. We must keep in mind that the condition has the possibility of leading to renal blood circulation disorders.

    2017-09-01

    Spontaneous coronary artery dissection (SCAD) is a non-atherosclerotic, non-traumatic cause of coronary artery dissection. SCAD is the most common cause of myocardial infarction in pregnancy or the postpartum period and results in significant cardiovascular morbidity and mortality in the pregnant population. It is important to consider pregnancy-associated spontaneous coronary artery dissection (PASCAD) high on the differential for a pregnant woman who presents with symptoms consistent with acute coronary syndrome. Management of these patients requires a thoughtful, multidisciplinary approach, with consideration of conservative management if possible. Counseling regarding future pregnancies is also critical and requires compassionate care. Given our limited understanding of SCAD, including PASCAD, more data and research are needed to help guide diagnosis, management, and determination of prognosis.

    Isolated aneurysms of the iliac arteries are rare. They must be considered as a disease pattern of their own as against aneurysms of the abdominal aorta because of the specific anatomical conditions in the pelvis. The clinical symptomatology is determinated by their localisation and topographical relationships within teh pelvis; this can give rise to problems in differential diagnosis primary urological, neurological or gastrointestinal diseases. The prognosis is decisively determined early and correct diagnosis because of the danger of rupture. Sonography, computed tomography and angiography are indispensable aids in preoperative planning.

    Full Text Available The extracranial internal carotid artery aneurysm (EICAA is an uncommon arterial lesion. Patients typically present with neurologic symptoms resulting from impaired cerebral perfusion and compression symptoms of cranial nerves. Often EICAA presents as a pulsatile neck mass, which is otherwise asymptomatic. We present a case of an 84-year-old female, who was initially referred to the Emergency Department for Otolaryngology with suspected peritonsillar abscess. The patient had a history of recent upper airway infection and cardiovascular comorbidities, including hypertension and ischaemic stroke complicated by extensive neurologic deficits. Physical examination revealed a compact, nonpulsatile mass in the lateral parapharyngeal space and local erythema of the mucosa. Duplex Doppler Ultrasonography and Computed Tomography revealed an atherosclerotic aneurysm of the right internal carotid artery, measuring 63×55×88 mm, stretching from the skull base to the angle of the mandible.

    Central nervous system vasculitis has multiple presentations, including stroke, seizures, cranial nerve palsies, and encephalopathy. We present the case of an unresponsive 45-year-old woman with vasculitis associated with fulminant intracranial vessel dissection and occlusion with ischemic strokes and subarachnoid hemorrhage secondary to aneurysm rupture. Imaging studies demonstrated both ischemic and hemorrhagic strokes. She had a ruptured right internal carotid artery dorsal variant aneurysm, right vertebral artery dissection with occlusion and posterior inferior cerebellar artery infarct, left vertebral artery dissection, and severe vasculitis involving intracranial and extracranial vessels. She initially was treated for her vasculitis with high-dose steroids followed by clip wrapping of the dorsal variant aneurysm. Unfortunately, her surgery was complicated by intraprocedural rupture, and the patient died during her hospitalization. Fulminant central nervous system vasculitis can occur with critical vascular anomalies that require emergent intervention and should be part of the differential diagnosis of patients presenting with these multiple vascular pathologies.

    Acute myocardial infarction during pregnancy is associated with high maternal and fetal mortality. Coronary atherosclerosis is the most common cause due to an increase in the age of the patients and the association with cardiovascular risk factors such as smoking, hypertension, diabetes mellitus, preeclampsia, and the existence of family history of coronary disease. However, thrombosis, coronary dissection or coronary vasospasms are other causes that may justify it. We report the case of a 33 weeks pregnant first-time mother, without cardiovascular risk factors, who presented an acute coronary event in the context of atherosclerotic disease and coronary dissection after percutaneous coronary intervention.

    This is a report about 4 patients with aneurysms of the superior mesenteric artery of arteriosclerotic, mycotic and probably congenital etiology together with a review of the literature as to the etiology, diagnostic possibilities and therapy. Arteriography is the method of choice even though a diagnosis may be possible by sonography or CT in special cases. Even though an aneurysm of the superior mesenteric artery is rare, it has to be considered in the differential diagnosis of persisting abdominal problems of unknown origin. This is especially true for patients with a predisposing history such as previous or existing endocarditis, sepsis, arteriosclerosis and hypertension. Because of the possibility of rupture followed by life threating bleeding an adequate diagnostic step such as arteriography has to be considered finally. (orig.) [de

    Objective: To summarize the main points of nursing cooperation in endovascular aneurysm repair treatment for aortic dissection. Methods: Preoperative psychological care and the other preparations were carefully conducted. During the operation, the patient's body was correctly placed. Active cooperation with the performance of angiography and close observation during heparinization were carried out. The proper delivery of catheter and stent to the operator was carefully done. Close observation for the patient's vital signs, the renal function and the changes of limb blood supply were made. Results: Under close cooperation of' the operators, nurses, anesthesiologists and technicians, the surgery was successfully accomplished in 35 patients. The monitoring of vital signs during the entire performance of operation was well executed. No surgical instruments delivery error's or surgery failure due to unsuitable cooperation occurred. Conclusion: Perfect preoperative preparation, strict nursing cooperation and team cooperation are the key points to ensure a successful endovascular aneurysm repair for aortic dissection. (authors)

    Gastroduodenal artery (GDA) aneurysm is a rare entity, comprising only 1.5% of all 3000 cases of visceral artery aneurysms that have been reported in literature. We report a case of a 55-year-old Caucasian man, diagnosed with right inguinal hernia. He was admitted to our department for surgical treatment. His medical history was remarkable for hypertension, and angina. He was operated the next day. A external oblique right inguinal hernia was diagnosed intraoperative. The Halsted technique was used for primary inguinal hernia. Immediate postoperative evolution was favorable, systolic blood pressure of 120 mmHg, pulse of 68 beats/minute. 16 h postoperative there was a sudden alteration of the general condition with signs of hemodynamic shock, with a systolic blood pressure of 60 mmHg, tachycardia of 110 beats/min. Physical examination revealed a pale, cold, and clammy patient. His hemoglobin had dropped from 14 g/dL on admission to 6 g/dL. A bedside ultrasound identified pelvic free fluid. An exploratory laparotomy revealed hemoperitoneum, and over 2 500 ml of blood and clot, a large hematoma was identified that was occupying the transvers colon mesentery and retroperitoneum. A clot was removed, revealing ruptured gastroduodenal artery aneurysm with active hemorrhage. The opening was isolated and closed. The contents were returned to the abdomen, which was irrigated and closed. Postoperative laboratory evaluation revealed hyperamylasemia (1543 IU/L, Normal Value (NV) = 15-95 IU/L). He remained normotensive throughout his 8-day hospitalization and was discharged home in good condition. In conclusion, gastroduodenal artery aneurysm rupture is a rare and patients can present with nonspecific symptoms. Rapid diagnosis, localization, and surgical or endovascular intervention are necessary to avoid devastating consequences.

    Aneurysm of the cystic artery is not common, and it is a rare cause of hemobilia. Most of reported cases are pseudoaneurysms resulting from either an inflammatory process in the abdomen or abdominal trauma. We report a healthy individual who developed hemobilia and acute pancreatitis associated with cystic artery aneurysm. The patient was managed with angio-embolization with an uneventful post-embolization course. Visceral artery aneurysms are rare and can rupture with potentially grave outcome due to excessive bleeding. Angiographic embolization as a common method of treatment for visceral artery aneurysms was used in our patient with good outcome.

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome and sudden cardiac death. It should be suspected in every healthy young woman without cardiac risk factors, especially during the peripartum or postpartum periods. It is important to check for a history of drug abuse, collagen vascular disease or blunt trauma of the chest. Coronary angiography is essential for diagnosis and early management. We wonder whether thrombolysis might aggravate coronary dissection. All types of treatment (medical therapy, percutaneous intervention or surgery) improve the prognosis without affecting survival times if used appropriately according to the clinical stability and the angiographic features of the involved coronary arteries. Prompt recognition and targeted treatment improve outcomes. We report a case of SCAD in a young female free of traditional cardiovascular risk factors, who presented six hours after thrombolysis for ST elevation myocardial infarction. Coronary angiography showed a dissection of the left anterior descending and immediate branch. She had successful coronary artery bypass grafting, with complete healing of left anterior descending dissection.

    Carotid artery dissection is an important cause of ischemic stroke in all age groups, particularly in young patients. The purpose of this work was to assess whether there is an association between the presence of an internal carotid artery dissection (ICAD) and the arterial tortuosity. This study considered 124 patients (72 males and 52 females; median age 57 years) with CT/MR diagnosis of ICAD of the internal carotid artery were considered in this multi-centric retrospective study. The arterial tortuosity was evaluated and, when present, was categorized as elongation, kinking, or coiling. For each patient, both the right and left sides were considered for a total number of 248 arteries in order to have the same number of cases and controls. Fisher's exact test was applied to test the association between elongation, kinking, coiling, dissection, and the side affected by CAD. Fisher's exact test showed a statistically significant association between the ICAD and kinking (p = 0.0089) and coiling (p = 0.0251) whereas no statistically significant difference was found with arterial vessel elongation (p = 0.444). ICAD was more often seen on the left side compared to the right (p = 0.0001). These results were confirmed using both carotid arteries of the same patient as dependent parameter with p = 0.0012, 0.0129, and 0.3323 for kinking, coiling, and elongation, respectively. The presence of kinking and coiling is associated with ICAD. (orig.)

    Full Text Available Introduction. Splenic artery aneurysms are potentially lethal lesions. We report two illustrative cases and discuss etiology, diagnosis and treatment of these aneurysms. Outline of Cases. Both patients, age 31 and 80 years, were biparous women. The younger woman, otherwise healthy, was referred from a local hospital 3 weeks after she underwent a left subcostal laparotomy and exploration for symptomatic abdominal mass diagnosed by CT. Angiography established the diagnosis of a large, non-ruptured splenic artery aneurysm. Elective aneurysmectomy with splenectomy was performed using the approach through the upper median laparotomy and bursa omentalis. Postoperative course was uneventful. Histopathology demonstrated cystic medial necrosis with chronic dissection. The other patient, elderly woman, presented urgently with acute abdominal pain and syncope and was diagnosed by computed tomography with a huge, ruptured splenic artery aneurysm. She underwent immediate aneurysmectomy with splenectomy using the same, above-mentioned approach. External pancreatic fistula and pancreatic pseudocyst complicated the postoperative course, requiring open pseudocyst drainage and cystojejunostomy. After a protracted hospitalization patient eventually recovered. The pathological diagnosis was atherosclerotic aneurysm. Conclusion. Splenic artery aneurysms are infrequent lesions, with varied etiology and clinical presentation. Timely diagnosis and adequate treatment prevent life-threatening rupture and lessen the risk of operative morbidity and mortality. [Projekat Ministarstva nauke Republike Srbije, br. 175008

    Full Text Available Aneurysmal disease affecting the aorta and visceral vessels in young patients is uncommon and typically associated with connective tissue disorders. We describe the case of a 17-year-old girl who presented with acute onset of abdominal pain; computed tomography scan revealed aortic and bilateral renal artery aneurysms and a perirenal hematoma. She was taken to the angiography suite; rupture of the right renal artery aneurysm was identified and immediately treated successfully with coil embolization. The left renal artery aneurysm was repaired with ex-vivo renal autotransplantation; 2 years later, the aorta and right renal artery underwent surgical reconstruction.

    Full Text Available We are reporting a case of familial thoracic aortic aneurysm and dissection in a 26-year-old man with no significant past medical history and a family history of dissecting aortic aneurysm in his mother at the age of 40. The patient presented with cough, shortness of breath, and chest pain. Chest X-ray showed bilateral pulmonary infiltrates. CT scan of the chest showed a dissection of the ascending aorta. The patient underwent aortic dissection repair and three months later he returned to our hospital with new complaints of back pain. CT angiography showed a new aortic dissection extending from the left carotid artery through the bifurcation and into the iliac arteries. The patient underwent replacement of the aortic root, ascending aorta, total aortic arch, and aortic valve. The patient recovered well postoperatively. Genetic studies of the patient and his children revealed no mutations in ACTA2, TGFBR1, TGFBR2, TGFB2, MYH11, MYLK, SMAD3, or FBN1. This case report focuses on a patient with familial TAAD and discusses the associated genetic loci and available screening methods. It is important to recognize potential cases of familial TAAD and understand the available screening methods since early diagnosis allows appropriate management of risk factors and treatment when necessary.

    Aneurysms located at the distal portion of the anterior inferior cerebellar artery (AICA) are rare, and their clinical features are not fully understood. We report the clinical features and management of nine distal AICA aneurysms in nine patients treated during the past decade at Kagoshima University Hospital and affiliated hospitals. Our series includes seven women and two men. Of their nine aneurysms, eight were ruptured and one was unruptured; six were saccular and three were dissecting aneurysms. The most prevalent location was the meatal loop (n = 5) followed by the postmeatal (n = 3) and premeatal segment (n = 1) of the AICA, suggesting hemodynamic stress as an etiology of these distal AICA aneurysms. Of the nine patients, five presented with angiographic features suggestive of increased hemodynamic stress to the AICA and the common trunk of the posterior inferior cerebellar artery, with vertebral artery stenosis, marked laterality, and a primitive hypoglossal artery. We addressed eight aneurysms (eight patients) surgically; one aneurysm in one patient disappeared in the course of 3 months without surgical treatment. Of the eight surgically treated aneurysms, seven were ruptured and one was unruptured, five were clipped via lateral suboccipital craniotomy, two were trapped via lateral suboccipital craniotomy, and one was embolized. Good outcomes were obtained in six of the eight patients who underwent operation (75 %). We consider increased hemodynamic stress attributable to anatomic variations in the AICA and related posterior circulation to be the predominant contributor to the development of distal AICA aneurysms. Direct clipping and trapping yielded favorable outcomes in our series.

    Spontaneous coronary artery dissection (SCAD) is a non-iatrogenic and non-traumatic separation of the coronary arterial wall. While SCAD represents an important cause of myocardial infarction, optimal diagnostic and therapeutic options remain challenging. We sought to review recent studies and provide an update on diagnosis and management of SCAD. Coronary angiography is the first-line diagnostic modality for SCAD, with three angiographic features commonly observed in SCAD: type 1 (pathognomonic angiographic appearance with contrast staining of the arterial wall), type 2 (long coronary stenosis), and type 3 (focal tubular stenosis). In addition, adjunctive intracoronary imaging can aid in identifying coronary dissections. Conservative management with beta-blockers and aspirin remains the mainstay of therapy. However, patients with high-risk features and recurrent symptoms may require revascularization. Several techniques have been reported, such as long stents to seal the entire length of the dissection, stepwise stenting starting at the distal edge followed by proximal edge stenting, use of bioabsorbable stents, and cutting balloon angioplasty. Furthermore, cardiac rehabilitation appears to be safe and offers significant benefits for patients with SCAD. Coronary angiographic classification contributed to the increased recognition of SCAD in recent years. Selecting the most suitable and appropriate therapy based on accurate diagnosis is the cornerstone of management in SCAD. Further studies are needed to establish optimal treatment of SCAD depending on anatomical and/or clinical features.

    Spontaneous coronary artery dissection (SCAD) is the most common cause of pregnancy-associated myocardial infarction and remains poorly characterized. This study sought to assess presentation, clinical factors, and outcomes of pregnancy-associated spontaneous coronary artery dissection (P-SCAD) compared with spontaneous coronary artery dissection not associated with pregnancy (NP-SCAD). A Mayo Clinic registry was established in 2010 to include comprehensive retrospective and prospective SCAD data. Records were reviewed to identify women who were pregnant or ≤12 weeks postpartum at time of SCAD. Complete records were available for 323 women; 54 women met criteria for P-SCAD (4 during pregnancy) and they were compared with 269 women with NP-SCAD. Most events occurred within the first month postpartum (35 of 50). Compared with NP-SCAD, P-SCAD patients more frequently presented with ST-segment elevation myocardial infarction (57% vs. 36%; p = 0.009), left main or multivessel SCAD (24% vs. 5%; p vs. 14%; p = 0.0027, respectively), and left ventricular function ≤35% (26% vs. 10%; p = 0.0071). Among women with imaging of other vascular territories, P-SCAD was less likely with a diagnosis of fibromuscular dysplasia and extracoronary vascular abnormalities (42% vs. 64%; p = 0.047; and 46% vs. 77%; p = 0.0032, respectively). Compared with U.S. birth data, women with P-SCAD were more often multiparous (p = 0.0167), had a history of infertility therapies (p = 0.0004), and had pre-eclampsia (p = 0.001). On long-term follow-up (median 2.3 years) recurrent SCAD occurred in 51 patients, with no difference in the Kaplan Meier 5-year recurrence rates (10% vs. 23%; p = 0.18). P-SCAD patients had more acute presentations and high-risk features than women with NP-SCAD did. The highest frequency of P-SCAD occurred during the first postpartum month and P-SCAD patients less often had extracoronary vascular abnormalities. Hormonal, hemodynamic variations, and yet

    2016-01-01

    Full Text Available Giant coronary artery aneurysms are rare clinical entities. We report the case of a 49-year-old man who presented with dyspnoea and exertional chest pain. Investigations confirmed an aneurysmal right coronary artery measuring 4 cm with a fistulous communication to the right atrium. Following right atriotomy, the fistula was oversewn and the aneurysmal right coronary artery ligated at its origin and at several points along its course. A saphenous vein graft was anastomosed to the posterior descending artery. Persistent ventricular fibrillation occurred upon chest closure, attributed to ischaemia following ligation of the aneurysmal coronary artery. Emergent resternotomy and internal defibrillation were successfully performed. The sternum was stented open to reduce right ventricular strain and closed the following day. The patient made an unremarkable recovery. We here address the technical challenges associated with surgical repair of right coronary aneurysms and the physiology and management of potential complications.

    K.-M. Park

    Full Text Available Introduction: Bilateral extracranial carotid artery aneurysms (ECAAs are very rare. The case of a patient with bilateral ECAA who underwent staged surgical repair is reported. Report: A 35 year old man was referred with a slow growing pulsatile neck mass causing mild discomfort. Computed tomography and duplex ultrasound showed a right ECAA, with a 3.0 cm diameter 5 cm long true aneurysm, and a left ECAA, with 2.1 cm diameter 4.5 cm long true aneurysm. In two stages, both aneurysms were excised and bypassed with an interposition graft using saphenous vein. Discussion: ECAAs are rare with an incidence of about 4% of all peripheral aneurysms. Selection of treatment options is largely dependent on the aneurysm anatomy, including size and length. During open repair, it is important to avoid nerve injury.

    Full Text Available Abstract Background Vertebral artery dissection (VAD is often associated with trauma or occurs spontaneously, inevitably causing some neurological deficits. Even though acute infection can be related to the development of spontaneous VAD (sVAD, VAD associated with viral meningitis has never been reported in the literature. Case presentation A 42-year-old man with fever, sore throat, and runny nose developed sudden onset of occipital headache, vertigo, transient confusion, diplopia, and ataxia. Brain stem encephalitis was diagnosed initially because the cerebrospinal fluid (CSF study showed inflammatory changes. However, subsequent diffusion-weighted (DWI magnetic resonance imaging of his brain demonstrated left lateral medullary infarction, and the digital subtraction angiography (DSA confirmed VAD involving left V4 segment of the artery. Consequently, the patient was diagnosed as VAD accompanied by viral meningitis. Conclusion This case suggests that viral meningitis might lead to inflammatory injury of the vertebral arterial wall, even sVAD with multiple neurological symptoms.

    2008-01-01

    Purpose: To report about the endovascular treatment of isolated iliac artery aneurysms (IIAA) with stentgraft placement and transluminal or CT-guided embolization of the internal iliac artery or the combination of these methods. Methods and materials: Over a period of 5.6 years, 36 interventions were performed in 20 patients with 23 IIAAs. In a retrospective analysis patient records were reviewed. The CT-angiography follow-up was evaluated for the presence of re-perfusion of the IIAA and for change of aneurysm diameter. Results: Primary success was achieved in 15/23 aneurysms (65%), and secondary success in 21/23 aneurysms (91%). In 5/23 cases two interventions and in 1/23 cases three interventions were necessary to achieve secondary success. Embolization alone, as a therapy for aneurysms involving only the internal iliac artery, had a success rate of 27%. No procedure-related minor or major complications occurred. Mean decrease of aneurysm size during a mean observation period of 14.1 months was 6.9% which was not significant (p = 0.3; 95% confidence interval +7-21%). Conclusion: Endovascular therapy of isolated iliac artery aneurysms performed percutaneously has become a treatment alternative to open surgical repair. This method is feasible and safe with low procedure-related morbidity and mortality. However, on average more than one intervention has to be performed to achieve successful permanent exclusion of the aneurysm and embolization alone in isolated internal iliac artery aneurysms is not sufficient

    Full Text Available There are many genetic syndromes associated with the aortic aneurysmal disease which include Marfan syndrome (MFS, Ehlers-Danlos syndrome (EDS, Loeys-Dietz syndrome (LDS, familial thoracic aortic aneurysms and dissections (TAAD, bicuspid aortic valve disease (BAV, and autosomal dominant polycystic kidney disease (ADPKD. In the absence of familial history and other clinical findings, the proportion of thoracic and abdominal aortic aneurysms and dissections resulting from a genetic predisposition is still unknown. In this study, we propose the review of the current genetic knowledge in the aortic disease, observing, in the results that the causative genes and molecular pathways involved in the pathophysiology of aortic aneurysm disease remain undiscovered and continue to be an area of intensive research.

    Dilation of the ascending aorta and aortic dissections are often seen in Marfan syndrome; however, true aneurysms of the subclavian and axillary arteries rarely seem to develop in patients who have this disease. We present the case of a 58-year-old man with Marfan syndrome who had undergone a Bentall procedure and thoracoabdominal aortic repair for an aortic dissection and who later developed multiple aneurysmal dilations of his right subclavian and axillary arteries. The aneurysms were successfully repaired by means of a surgical bypass technique in which a Dacron graft was placed between the carotid and brachial arteries. We also discuss our strategy for determining the optimal surgical approach in these patients.

    Marfan syndrome has a pleomorphic phenotype. Those affected have abnormalities in the eyes and in the nervous, cardiovascular and musculoskeletal systems. Among these abnormalities are many reported aneurysms, involving the ascending, descending thoracic and abdominal aorta, the sinus of Valsalva, and the internal carotid artery. We report a left internal mammary artery (LIMA) aneurysm in a patient with Marfan syndrome and no other known predisposition to such an aneurysm. No other case of LIMA aneurysm in Marfan syndrome has, to our knowledge, been reported. (author)

    Purpose. To evaluate the safety and efficacy of stent placement for extracranial and intracranial arterial dissections. Methods. Eighteen patients underwent endovascular treatment of carotid and vertebral dissections using intraluminal stent placement. Five patients with arterial dissection were treated, 2 using one insertion of a single stent and 3 using placement of two stents. Patients with a dissecting aneurysm were treated as follows: 7 patients with insertion of one stent, 4 with placement of two stents, and 2 by stent-assisted Guglielmi detachable coil embolization. In the 18 patients in whom stenting was attempted, the overall success in reaching the target lesion was 94.4%. Of the 17 patients treated with stents, stent release and positioning were considered optimal in 16 (94%) and suboptimal in one (6%). In patients who underwent a successful procedure, all parent arteries were preserved. There were no instances of postprocedural ischemic attacks, new neurologic deficits, or new minor or major strokes prior to patient discharge. In follow up, all patients were assessed, using the modified Rankin scale, as functionally improved or of stable clinical status. The reduction in dissection-induced stenosis or pseudoaneurysm, the patency rate obtained at follow-up, and the lack of strokes (ischemic or hemorrhagic) suggest that stent placement offers a viable alternative to complex surgical bypass or reconstructive procedures. The long-term efficacy and durability of stent placement for arterial dissection remain to be determined in a larger series

  8. Flash fluorescence with indocyanine green videoangiography to identify the recipient artery for bypass with distal middle cerebral artery aneurysms: operative technique.

    Distal middle cerebral artery (MCA) aneurysms frequently have nonsaccular morphology that necessitates trapping and bypass. Bypasses can be difficult because efferent arteries lie deep in the opercular cleft and may not be easily identifiable. We introduce the "flash fluorescence" technique, which uses videoangiography with indocyanine green (ICG) dye to identify an appropriate recipient artery on the cortical surface for the bypass, enabling a more superficial and easier anastomosis. Flash fluorescence requires 3 steps: (1) temporary clip occlusion of the involved afferent artery; (2) videoangiography demonstrating fluorescence in uninvolved arteries on the cortical surface; and (3) removal of the temporary clip with flash fluorescence in the involved efferent arteries on the cortical surface, thereby identifying a recipient. Alternatively, temporary clips can occlude uninvolved arteries, and videoangiography will demonstrate initial fluorescence in efferent arteries during temporary occlusion and flash fluorescence in uninvolved arteries during reperfusion. From a consecutive series of 604 MCA aneurysms treated microsurgically, 22 (3.6%) were distal aneurysms and 11 required a bypass. The flash fluorescence technique was used in 3 patients to select the recipient artery for 2 superficial temporal artery-to-MCA bypasses and 1 MCA-MCA bypass. The correct recipient was selected in all cases. The flash fluorescence technique provides quick, reliable localization of an appropriate recipient artery for bypass when revascularization is needed for a distal MCA aneurysm. This technique eliminates the need for extensive dissection of the efferent artery and enables a superficial recipient site that makes the anastomosis safer, faster, and less demanding.

    Fluoroquinolones have been associated with collagen degradation, raising safety concerns related to more serious collagen disorders with use of these antibiotics, including aortic aneurysm and dissection. To examine the relationship between fluoroquinolone therapy and the risk of developing aortic aneurysm and dissection. We conducted a nested case-control analysis of 1477 case patients and 147 700 matched control cases from Taiwan's National Health Insurance Research Database (NHIRD) from among 1 million individuals longitudinally observed from January 2000 through December 2011. Cases patients were defined as those hospitalized for aortic aneurysm or dissection. One hundred control patients were matched for each case based on age and sex. Current, past, or any prior-year use of fluoroquinolone. Current use was defined as a filled fluoroquinolone prescription within 60 days of the aortic aneurysm or dissection; past use refers to a filled fluoroquinolone prescription between 61 and 365 days prior to the aortic aneurysm; and any prior-year use refers to having a fluoroquinolone prescription filled for 3 or more days any time during the 1-year period before the aortic aneurysm or dissection. Risk of developing aortic aneurysm or dissection. A total of 1477 individuals who experienced aortic aneurysm or dissection were matched to 147 700 controls. After propensity score adjustment, current use of fluoroquinolones was found to be associated with increased risk for aortic aneurysm or dissection (rate ratio [RR], 2.43; 95% CI, 1.83-3.22), as was past use, although this risk was attenuated (RR, 1.48; 95% CI, 1.18-1.86). Sensitivity analysis focusing on aortic aneurysm and dissection requiring surgery also demonstrated an increased risk associated with current fluoroquinolone use, but the increase was not statistically significant (propensity score-adjusted RR, 2.15; 95% CI, 0.97-4.60). Use of fluoroquinolones was associated with an increased risk of aortic aneurysm and

    Intracranial aneurysms are sometimes presented with visual symptoms by their rupture or direct compression of the optic nerve. It is because their prevalent sites are anatomically located close to the optic pathway. Anterior communicating artery is especially located in close proximity to optic nerve. Aneurysm arising in this area can produce visual symptoms according to their direction while the size is small. Clinical importance of visual symptoms presented by aneurysmal optic nerve compression is stressed in this study. Retrospective analysis of ruptured anterior communicating artery aneurysms compressing optic apparatus were carried out. Total 33 cases were enrolled in this study. Optic nerve compression of the aneurysms was confirmed by the surgical fields. In 33 cases among 351 cases of ruptured anterior communicating artery aneurysms treated surgically, from 1991 to 2000, the dome of aneurysm was compressed in optic pathway. In some cases, aneurysm impacted into the optic nerve that deep hollowness was found when the aneurysm sac was removed during operation. Among 33 cases, 10 cases presented with preoperative visual symptoms, such as visual dimness (5), unilateral visual field defect (2) or unilateral visual loss (3), 20 cases had no visual symptoms. Visual symptoms could not be checked in 3 cases due to the poor mental state. In 6 cases among 20 cases having no visual symptoms, optic nerve was deeply compressed by the dome of aneurysm which was seen in the surgical field. Of 10 patients who had visual symptoms, 8 showed improvement in visual symptoms within 6 months after clipping of aneurysms. In 2 cases, the visual symptoms did not recover. Anterior communicating artery aneurysm can cause visual symptoms by compressing the optic nerve or direct rupture to the optic nerve with focal hematoma formation. We emphasize that cerebral vascular study is highly recommended to detect intracranial aneurysm before its rupture in the case of normal CT findings with

    We aimed to evaluate risk factors of sis-VADAs recurrence after reconstructive treatment based on 113 reconstructed lesions. A total of 111 patients (M:F = 68:43; median age, 47 years) with 113 sis-VADAs underwent reconstruction from October 2000 to March 2011, using stent(s) and coils. Treatments and predictors of recurrence were retrospectively analysed. Fifty-eight sis-VADAs underwent single-stent treatment, and the remaining 55 sis-VADAs underwent treatment with 2-4 overlapping stents. Follow-up angiography was available for 94 sis-VADAs 12 -78 months, with recurrence in ten patients, including seven angiographic recurrences and three post-treatment haemorrhagic recurrences. A higher rate of post-treatment recurrence was observed in the single stent group than in the multiple stents group (p = 0.010). The interaction between stent (s) implantation and immediate occlusion degree (odds ratio [OR] =3.152; 95% confidence interval [CI], 1.293-7.686; p = 0.012), between stent (s) implantation and the posterior inferior cerebellar artery (PICA) involvement (OR = 4.607; 95% CI, 1.172-18.113; p = 0.029), and between PICA involvement and immediate occlusion degree (OR = 5.018; 95% CI, 1.263-19.933; p = 0.022) affect recurrence in the reconstructed sis-VADAs. This single centre cohort study indicated that the interaction effect between stent (s) implantation, PICA involvement, and immediate occlusion degree were closely associated with recurrence after reconstructive treatment of sis-VADA. The interaction between stent (s) and immediate occlusion degree affect aneurysmal recurrence. The interaction between stent and PICA involvement affect aneurysmal recurrence. The interaction between PICA involvement and immediate occlusion degree affect aneurysmal recurrence.

  13. Vertebral Artery Dissection Complicated by Basilar Artery Occlusion

    Full Text Available Acute basilar artery occlusion (ABAO is an infrequent but potentially fatal complication that can cause strokes in both adults and children. Traumatic vertebral artery dissection (VAD is one of the most common causes of ABAO in young patients. We present a case of an 11-year-old boy with VAD complicated by basilar artery occlusion 2 days after a fight with classmates that caused severe neurological deficits. He did not have any direct head trauma or concomitant risk factors. Clinical symptoms included nausea, vomiting, and rapid alteration of consciousness. Magnetic resonance imaging showed total occlusion of the basilar artery, and angiography confirmed VAD from the third to the fourth segments. A history of such subtle precipitating events should be noted when diagnosing young patients with brainstem strokes. A delay in the diagnosis of ABAO is frequently due to misleading symptoms and signs and the lack of awareness of this rare condition.

    Anterior inferior cerebellar artery (AICA) aneurysms are very rare. We carried out four direct operations for AICA aneurysms including two distal AICA aneurysms using lateral suboccipital retrosigmoid approaches (LSRA). We successfully performed the clipping by LSRA. but hearing loss occurred except in one of our cases which involved a chronic term operation in in our cases, In a 72 years old female with a ruptured dissecting aneurysm of the AICA anterior pontine segment, we performed the OA-PICA anastomosis first because of its being an AICA-PICA type, and then we continued to carry out the trapping operation of dissecting artery on day 0. She left our hospital cheerfully but hearing loss persisted on the operated side. Four examples of the dissecting aneurysm of AICA anterior pontine segment have been reported, but only our case involved the trapping with revascularization in acute stage. At the moment, there is no clinical or useful classification for distal AICA aneurysm because it is extremely rare. We will now propose a new classification. This classification is divided into two groups, (1) P (pons) -group and (2) C (cerebellum) -group. The P-group consists of pA (AICA anterior pontine segment). pL (lateral branch on the pons to the meatal loop) and pM (medial branch on the pons). C-group consists of m-loop (meatal loop), cL (lateral branch post meatal loop) and cM (medial branch on the cerebellum). From results of case reports (75 distal AICA aneurysms), we found that pA: 5 (6.7%), pL: 2 (2.8%), pM: 0, m-loop: 54 (72%), cL: 8 (11%), cM: 6 (8.3%). The followings factors were also found. (1) Occlusion of the parent artery of P-group without revascularization of peripheral circulation may entail the risk of death. (2) On the other hand, as for the C-group, the parent artery was able to be occluded without severe consequences, but hearing loss and/or cerebellar infarction occurred. We believe that this classification is simple and very useful for therapeutic

    Full Text Available The article presents the pathologic changes in the aortic wall in patients with MFS (three men at the age of 25, 27, 35 years operated on the aneurysm with dissection of the ascending aorta. Morphological changes in the middle of the shell of the aorta in patients with MFS were characterized by severe restructuring with profound irreversible alterative changes in all of its components. The pathological process captured media of the aorta throughout its entire length, not just in the areas of rupture and separation. The main pathomorphological signs of MFS were the focal accumulation of mucoid substances, ribbon-like nuclear-free zones, degenerative changes in smooth muscle cells, the formation of cystic media degeneration cavities, changes in elastic fibers - fragmentation, hyperelastosis, multiplication, thinning and straightening, areas of significant elastolysis. Multiple CMD was detected in all patients with MFS, the changes revealed the same type, but at different stages of the process.

    Aneurysms of the posterior cerebral artery (PCA) are rare, and most of the studies reported in the literature in which the endovascular approach was applied were carried out on a limited number of patients with PCA aneurysms. We retrospectively reviewed our cases of PCA aneurysms - at various locations and of differing shapes - that received endovascular treatment and evaluated the treatment outcome. From January 1996 to December 2006, 13 patients (eight females and five males) with 17 PCA aneurysms (nine fusiform and eight saccular) were treated using the endovascular approach. The age of the patients ranged from 20 to 67 years, with a mean age of 44 years. Of the 13 patients, ten presented with intracranial hemorrhage, and one patient, with a large P2 aneurysm, presented with trigeminal neuralgia; the aneurysms were asymptomatic in the remaining two patients. All 13 patients were successfully treated, with only one procedure-related symptomatic complication. Seven patients were treated by occlusion of the aneurysm and parent artery together; five patients, by selective embolization of the aneurysm; one patient, by partial coiling. Although infarctions were found in two patients treated with selective embolization and in three patients treated with parent artery occlusion, only one patient with a ruptured P2 aneurysm treated with parent artery occlusion developed transient amnesia as an ischemic symptom. Posterior cerebral artery aneurysms can be treated safely with either occlusion of the aneurysm together with the PCA or with a selective coil embolization. Infarctions may occur after endovascular treatment, but they are rarely the cause of a disabling symptom. (orig.)

    The ascending thoracic aorta is designed to withstand biomechanical forces from pulsatile blood. Thoracic aortic aneurysms and acute aortic dissections (TAADs) occur as a result of genetically triggered defects in aortic structure and a dysfunctional response to these forces. Here, we describe mutations in the forkhead transcription factor FOXE3 that predispose mutation-bearing individuals to TAAD. We performed exome sequencing of a large family with multiple members with TAADs and identified a rare variant in FOXE3 with an altered amino acid in the DNA-binding domain (p.Asp153His) that segregated with disease in this family. Additional pathogenic FOXE3 variants were identified in unrelated TAAD families. In mice, Foxe3 deficiency reduced smooth muscle cell (SMC) density and impaired SMC differentiation in the ascending aorta. Foxe3 expression was induced in aortic SMCs after transverse aortic constriction, and Foxe3 deficiency increased SMC apoptosis and ascending aortic rupture with increased aortic pressure. These phenotypes were rescued by inhibiting p53 activity, either by administration of a p53 inhibitor (pifithrin-α), or by crossing Foxe3–/– mice with p53–/– mice. Our data demonstrate that FOXE3 mutations lead to a reduced number of aortic SMCs during development and increased SMC apoptosis in the ascending aorta in response to increased biomechanical forces, thus defining an additional molecular pathway that leads to familial thoracic aortic disease.

    Full Text Available Aneurysms in various arterial beds have common risk- and genetic factors. Data on the correlation of extracranial carotid artery aneurysms (ECAA with aneurysms in other vascular territories are lacking. We aimed to investigate the prevalence of ECAA in patients with an intracranial aneurysm (IA.We used prospectively collected databases of consecutive patients registered at the University Medical Center Utrecht with an unruptured intracranial aneurysm (UIA or aneurysmal Subarachnoid hemorrhage (SAH. The medical files of patients included in both databases were screened for availability of radiological reports, imaging of the brain and of the cervical carotid arteries. All available radiological images were then reviewed primarily for the presence of an ECAA and secondarily for an extradural/cavernous carotid or vertebral artery aneurysm. An ECAA was defined as a fusiform dilation ≥150% of the normal internal or common carotid artery or a saccular distention of any size.We screened 4465 patient records (SAH database n = 3416, UIA database n = 1049, of which 2931 had radiological images of the carotid arteries available. An ECAA was identified in 12/638 patients (1.9%; 95% CI 1.1-3.3 with completely imaged carotid arteries and in 15/2293 patients (0.7%; 95% CI 0.4-1.1 with partially depicted carotid arteries. Seven out of 27 patients had an additional extradural (cavernous or vertebral artery aneurysm.This comprehensive study suggests a prevalence for ECAA of approximately 2% of patients with an IA. The rarity of the disease makes screening unnecessary so far. Future registry studies should study the factors associated with IA and ECAA to estimate the prevalence of ECAA in these young patients more accurately.

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare cause of acute myocardial infarction that is more common in younger patients (under age 50 and in women. Although the etiology is not known, some predisposing conditions to SCAD are well known and include Marfan syndrome, pregnancy and peripartum state, drug abuse, and some anatomical abnormalities of the coronary arteries such as aneurysms and severe kinking. We describe a case of SCAD in a young woman who presented with sudden onset of chest pain and was admitted for the treatment of acute coronary syndrome. The coronary angiography showed dissection of the left anterior descending artery. The patient underwent successful percutaneous transluminal coronary angioplasty and stent placement.

    Most aneurysms of hand arteries are traumatic. It is a generally rare unrecognized pathology. Complications are serious (embolism and thromboses of interdigital arteries). Two main causes can be recalled: acute trauma, with development of a false aneurysm; repeated microtrauma (hand hammer syndrome), with occurrence of an arterial dysplasic aneurysm. The diagnosis is based on the presence of a pulsatile mass, with finger dysesthesia, unilateral Raynaud's phenomenon. It is confirmed by duplex Doppler. Arteriography is necessary but can be replaced by an angio-MR. We report a case of false traumatic aneurysm of the ulnar artery in a teenager. This case illustrates this rare condition and opens discussion on therapeutic options. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Spontaneous coronary artery dissection (SCAD) is an uncommon disease. We report the case of a 50 year-old woman with a past medical history of aneurysmal subarachnoid hemorrhage, presenting with acute chest pain and diffuse ST segment elevation on ECG. Coronary angiogram revealed a SCAD of the left anterior descending coronary artery. The association between cerebral aneurysms and SCAD should trigger providers concern for fibromuscular dysplasia. We hereby report on a rare and atypical case involving the relationship between fibromuscular dysplasia and SCAD.

    A review of 4,500 angiograms yielded 11 patients with dissection of the vertebral arteries who had MRI and (in 4 patients) MR angiography (MRA) in the acute phase of stroke. One patient with incidental discovery at arteriography of asymptomatic vertebral artery dissection and two patients with acute strokes with MRI and MRA findings consistent with vertebral artery dissection were included. Dissection occurred after neck trauma or chiropractic manipulation in 4 patients and was spontaneous in 10. Dissection involved the extracranial vertebral artery in 9 patients, the extra-intracranial junction in 1, and the intracranial artery in 4. MRI demonstrated infarcts in the brain stem, cerebellum, thalamus or temporo-occipital regions in 7 patients with extra- or extra-intracranial dissections and a solitary lateral medullary infarct in 4 patients (3 with intracranial and 1 with extra-intracranial dissection). In 2 patients no brain abnormality related to vertebral artery dissection was found and in one MRI did not show subarachnoid haemorrhage revealed by CT. Intramural dissecting haematoma appeared as crescentic or rounded high signal on T1-weighted images in 10 patients examined 3-20 days after the onset of symptoms. The abnormal vessel stood out in the low signal cerebrospinal fluid in intracranial dissections, whereas it was more difficult to detect in extracranial dissections because of the intermediate-to-high signal of the normal perivascular structures and slow flow proximal and distal to the dissection. In two patients examined within 36 h of the onset, mural thickening was of intermediate signal intensity on T1-weighted images and high signal on spin-density and T2-weighted images. MRA showed abrupt stenosis in 2 patients and disappearance of flow signal at and distal to the dissection in 5. Follow-up arteriography, MRI or MRA showed findings consistent with occlusion of the dissected vessel in 6 of 8 patients. (orig.). With 7 figs., 3 tabs.

    Full Text Available Upper extremity peripheral artery aneurysms are rare, and have been previously reported in children to be associated with congenital malformations and infectious or inflammatory processes. In this case series, we present two unique cases of spontaneous isolated true aneurysms of the brachial artery in two children. Both cases were incidentally found on examination, diagnosed by ultrasonography, and successfully managed by surgical excision and micro-vascular repair with vein grafting.

    Full Text Available Introduction. Reconstruction of chronic type B dissection and thoracoabdominal aortic aneurysm (TAAA remaining after the emergency reconstruction of the ascending thoracic aorta and aortic arch for acute type A dissection represents one of the major surgical challenges. Complications of chronic type B dissection are aneurysmal formation and rupture of an aortic aneurysm with a high mortality rate. We presented a case of visceral hybrid reconstruction of TAAA secondary to chronic dissection type B after the Bentall procedure with the elephant trunk technique due to acute type A aortic dissection in a high-risk patient. Case report. A 62 year-old woman was admitted to our institution for reconstruction of Crawford type I TAAA secondary to chronic dissection. The patient had had an acute type A aortic dissection 3 years before and undergone reconstruction by the Bentall procedure with the elephant trunk technique with valve replacement. On admission the patient had coronary artery disease (myocardial infarction, two times in the past 3 years, congestive heart disease with ejection fraction of 25% and chronic obstructive pulmonary disease. On computed tomography (CT of the aorta TAAA was revealed with a maximum diameter of 93 mm in the descending thoracic aorta secondary to chronic dissection. All the visceral arteries originated from the true lumen with exception of the celiac artery (CA, and the end of chronic dissection was below the origin of the superior mesenteric artery (SMA. The patient was operated on using surgical visceral reconstruction of the SMA, CA and the right renal artery (RRA as the first procedure. Postoperative course was without complications. Endovascular TAAA reconstruction was performed as the second procedure one month later, when the elephant trunk was used as the proximal landing zone for the endograft, and distal landing zone was the level of origin of the RRA. Postoperatively, the patient had no neurological deficit and

    Full Text Available Pulmonary artery dissection is extremely rare but it is a really life-threatening condition when it happens. Most patients die suddenly from major bleeding or tamponade caused by direct rupture into mediastinum or retrograde into the pericardial sac. What we are reporting is a rare case of a 46-year-old female patient whose pulmonary artery dissection involves both the pulmonary valve and right pulmonary artery. The patient had acute chest pain and severe dyspnea, and the diagnosis of pulmonary artery dissection was confirmed by ultrasonography and CT angiography. Moreover, its etiology, clinical manifestations, and management are also discussed in this article.

    Aneurysms may arise at various locations along the course of the posterior inferior cerebellar artery. Brainstem and cranial nerves manipulation make the surgical approach to proximal aneurysms difficult, while the occlusion of the parent vessel is sometimes unavoidable in peripheral aneurysms. Endovascular treatment can be a good alternative, but also with this approach the location of the aneurysm is critical. If occlusion of the parent vessel is planned, anatomical variations and vascular territories of the brainstem should be considered. We report our experience with 18 consecutive aneurysms (12 proximal, 6 peripheral) treated by coils. Complete occlusion was achieved in 14 patients and subtotal in 4. In three patients the parent vessel had to be sacrificed. During treatment two perforations occurred; aneurysms were completely occluded without clinical consequences. Two small asymptomatic cerebellar infarctions were seen on postoperative computed tomography. Clinical outcome was good in 16 patients. (orig.)

    We investigated whether university education is more likely in cervical artery dissection (CeAD)-patients than in age- and sex-matched patients with ischemic stroke (IS) due to other causes (non-CeAD-IS-patients). Patients from the Cervical Artery Dissection and Ischemic Stroke Patients study with documented self-reported profession before onset of IS due to CeAD (n = 715) or non-CeAD causes (n = 631) were analyzed. In the reported profession, the absence or presence of university education was assessed. Professions could be rated as academic or non-academic in 518 CeAD and 456 non-CeAD patients. Clinical outcome at 3 months was defined as excellent if modified Rankin Scale was 0-1. University education was more frequent in CeAD-patients (100 of 518, 19.3%) than in non-CeAD-IS-patients (61 of 456, 13.4%, p = 0.008). CeAD-patients with and without university education differed significantly with regard to smoking (39 vs. 57%, p = 0.001) and excellent outcome (80 vs. 66%, p = 0.004). In logistic regression analysis, university education was associated with excellent outcome in CeAD-patients (OR 2.44, 95% CI 1.37-5.38) independent of other outcome predictors such as age (OR 0.97, 95% CI 0.84-0.99), NIHSS (OR 0.80, 95% CI 0.76-0.84) and local signs (OR 2.77, 95% CI 1.37-5.57). We observed a higher rate of university education in patients with CeAD compared with non-CeAD patients in our study population. University education was associated with favorable outcome in CeAD-patients. The mechanism behind this association remains unclear.

    Summary We report a rare case of a ruptured distal anterior inferior cerebellar artery (possibly dissecting) aneurysm of the caudal trunk, successfully treated by endovascular occlusion. A 41-year-old man presented with sudden severe headache and drowsiness. On the day of ictus, conventional angiography was performed to make the above diagnosis, followed by endovascular occlusion of the sac and the parent artery. The patient recovered completely without any neurologic deficit after treatment. Endovascular occlusion could be a safe and effective treatment option in a case of a ruptured distal AICA aneurysm of the caudal trunk. PMID:20566118

    2006-03-01

    In this study, the effects of unequal physiologic flow conditions in the internal carotid arteries on the intra-aneurysmal hemodynamics of anterior communicating artery aneurysms were investigated. Patient-specific vascular computational fluid dynamics models of five cerebral aneurysms were constructed from bilateral 3D rotational angiography images. The aneurysmal hemodynamics was analyzed under a range of physiologic flow conditions including the effects of unequal mean flows and phase shifts between the flow waveforms of the left and right internal carotid arteries. A total of five simulations were performed for each patient, and unsteady wall shear stress (WSS) maps were created for each flow condition. Time dependent curves of average WSS magnitude over selected regions on the aneurysms were constructed and used to analyze the influence of the inflow conditions. It was found that mean flow imbalances in the feeding vessels tend to shift the regions of elevated WSS (flow impingement region) towards the dominating inflow jet and to change the magnitude of the WSS peaks. However, the overall qualitative appearance of the WSS distribution and velocity simulations is not substantially affected. In contrast, phase differences tend to increase the temporal complexity of the hemodynamic patterns and to destabilize the intra-aneurysmal flow pattern. However, these effects are less important when the A1 confluence is less symmetric, i.e. dominated by one of the A1 segments. Conditions affecting the flow characteristics in the parent arteries of cerebral aneurysms with more than one avenue of inflow should be incorporated into flow models.

    The case of a 13-month-old boy with fibromuscular dysplasia (FMD) presenting with a large saccular aneurysm of the left renal artery and renovascular hypertension is reported. Renal and intrarenal arteries showed numerous small aneurysms alternating with stenoses. All arterial lesions were localized to the left kidney. After left nephrectomy, the patient's blood pressure normalized. Histopathologic examination of the arteries disclosed changes typical of medial fibroplasias, the most frequently described form of FMD in children. This diagnosis is rewarding as it represents a surgically curable cause of severe hypertension. (orig.)

    Future aneurysmal behaviors or treatment outcomes of cerebral aneurysms may be related to the hemodynamics around the inflow zone. Here we investigated the influence of parent artery curvature on the inflow zone location of unruptured sidewall internal carotid artery aneurysms. In 32 aneurysms, the inflow zone location was decided by 4D flow MR imaging, and the radius of the parent artery curvature was measured in 2D on an en face image of the section plane corresponding to the aneurysm orifice. The inflow zone was on the distal neck in 10 (group 1, 31.3%), on the lateral side in 19 (group 2, 59.4%), and on the proximal neck in 3 (group 3, 9.4%) aneurysms. The radius in group 1 was significantly larger than that in group 2 (8.3 mm [4.5 mm] versus 4.5 mm [1.9 mm]; median [interquartile range]; P 8.0 mm were in group 1. All 18 aneurysms with a radius of <6.0 mm were in group 2 or 3. In two group 3 aneurysms, the inflow zone was located in a part of the neck extending beyond the central axis of the parent artery. The inflow zone locations of sidewall aneurysms can be influenced by the parent artery curvature evaluated in 2D on an en face image of the section plane corresponding to the aneurysm orifice. © 2015 by American Journal of Neuroradiology.

    Full Text Available Background. Cervicocephalic arterial dissection (CCAD is rare in the postpartum period. To our knowledge this is the first reported case of postpartum angiopathy (PPA presenting with ischemic stroke due to intracranial arterial dissection. Case. A 41-year-old woman presented with blurred vision, headache, and generalized seizures 5 days after delivering twins. She was treated with magnesium for eclampsia. MRI identified multiple posterior circulation infarcts. Angiography identified a complex dissection extending from both intradural vertebral arteries, through the basilar artery, and into both posterior cerebral arteries. Multiple segments of arterial dilatation and narrowing consistent with PPA were present. Xenon enhanced CT (Xe-CT showed reduced regional cerebral blood flow that is improved with elevation in blood pressure. Conclusion. Intracranial vertebrobasilar dissection causing stroke is a rare complication of pregnancy. Eclampsia and PPA may play a role in its pathogenesis. Blood pressure management may be tailored using quantitative blood flow studies, such as Xe-CT.

    We report a 3-day-old boy with double outlet of the right ventricle and interruption of the aortic arch who developed spontaneous dissection of the arterial duct (DA) despite use of continuous infusion of lipo-prostaglandin E1 (PGE1). Transthoracic echocardiography demonstrated the spontaneous dissecting aneurysm of DA, which was confirmed by histology at the modified Norwood procedure done at age of 18 days. This is the first report of spontaneous dissection of DA in a neonate receiving PGE1, suggesting a new closing mechanism of DA.

    When treating dissecting aneurysm of the thoracoabdominal aorta surgically in patients with Marfan syndrome, we have usually performed graft replacement- including the entire thoracoabdominal aorta and reconstruction of all visceral branches, even if dilatation is mild in some segments-to avoid further aortic operations in the follow-up period. From October 1999 through July 2011, 20 consecutive patients with Marfan syndrome underwent repair of dissecting aneurysm of the thoracoabdominal aorta (median age, 45 years; range, 19-65 years). All patients underwent surgical intervention with cerebrospinal fluid (CSF) drainage and distal aortic and selective organ perfusion. Deep hypothermia was used in 13 patients for spinal cord protection. No in-hospital mortality was observed. One patient had temporary spinal cord ischemia but was fully recovered by discharge. Other complications included exploration for bleeding (n=1), prolonged ventilation (n=1), and graft infection (n=1). At a mean follow-up of 54 months (range, 9-129 months), 1 patient had died of interstitial pneumonia at 38 months postoperatively. Survival at 8% years was 91.2±9.0%. Two patients required additional aortic procedures (total arch replacement and aortic valve-sparing surgery). Actuarial rate of freedom from aortic operations at 8 years was 83.9%±10.5%, but no patient needed required repeated thoracotomy for an aortic procedure. Neither false nor patch aneurysms were observed using computed tomography (CT) during follow-up surveillance. Graft replacement for dissecting aneurysm of the thoracoabdominal aorta in Marfan syndrome offers good early and long-term results. We believe total aortic replacement including the entire thoracoabdominal aorta and reconstruction of all visceral arteries should be recommended for selected patients with Marfan syndrome.

    Full Text Available Background. Rupture of a splenic artery aneurysm is rare complication of pregnancy that is associated with a significant maternal and fetal mortality. Case. A multiparous female presented in the third trimester with hypotension, tachycardia, and altered mental status. A ruptured splenic artery aneurysm was discovered at the time of laparotomy and cesarean delivery. The patient made a full recovery following resection of the aneurysm. The neonate survived but suffered severe neurologic impairment. Conclusion. The diagnosis of ruptured splenic artery aneurysm should be considered in a pregnant woman presenting with signs of intra-abdominal hemorrhage. Early intervention by a multidisciplinary surgical team is key to preserving the life of the mother and fetus.

    Objective: To study the necessity of radionuclide dynamic renal imaging before the operation for the patients with dissecting aneurysm of aorta. Methods: Twenty-five normal subjects (male: female = 16:9, average age 48.32 ± 10.09) and 54 patients with dissecting aneurysm of aorta (male:female 44:10, average age 54.39 ± 11.55) were included in this study. Twenty-four of them belonged to Debackey I and 30 belonged to Debackey III. They were divided into 3 groups according to the situation of renal function and all of the study groups underwent renal scintigraphy. During the study, time of peak (T p ), half clearing time (T 1/2 ), clear rate of 20 min (CR 20min ) were measured. Results: Renal scintigraphy of 25 normal subjects showed: 1) both kidneys appeared 2 min later than abdominal aorta developed; 2) both kidneys were in the normal position, and with normal shape and size; 3) T p : (2.89 ± 0.76) min, T 1/2 :(7.24 ± 1.64) min, CR 20min : (69.87 ± 5.45)%. The scintigraphic results of the 54 patients with dissecting aneurysm of aorta showed: 1) Group 1, both renal developing time and renal function of both kidneys were in the normal range; 2) Group 2, the sizes of two kidneys were obviously different, renal developing time of the abnormal kidney was extended, and the renal function of two kidneys were different from each other; 3) Group 3, the renal developing time and renal function of both kidneys were abnormal, and were significantly different from that in the control group and group 1. Conclusions: The renal artery is easy to be involved leading to low perfusion and renal insufficiency in the case of dissecting aneurysm of aorta belonging to either Debackey I or III. Renal scintigraphy is more sensitive in renal perfusion and function estimation than other noninvasive examinations, and it could demonstrate early involvement of renal vessels and renal function, this situation is of close relationship with the selection of the operation program and the

    2008-12-01

    Full Text Available Naturally formed arteriovenous fistula (AVF causing local vascular aneurysm dilatation in the forearm ulnar artery region is rare and is exceedingly uncommon in any age group. Presented is a case of AVF in the left ulnar artery of a 39-year-old man in whom there was no history of trauma; the deformity had been noted since childhood. The AVF had become tortuous and enlarged in size as the patient aged. As a result, aneurysm dilatation formed on the base of the AVF and that of the ulnar artery origin. Despite normal preoperative Allen test result and normal preoperative finger pressure measurement with ulnar artery occlusion, arterial duplex imaging showed that the radial artery was the dominant artery of the left arm; the AVF was resected and the base of the aneurismal dilatation, which was directly related to the ulnar artery, was repaired for the sake of the natural continuity of ulnar blood flow.

    Anatomic factors may limit the application of stent grafts for the treatment of arterial aneurysms. Flow- diverting stents (FDSs) are specially designed to reduce flow velocity in the aneurysm sac and promote thrombosis while maintaining flow in the main artery and branch vessels. FDSs include the Pipeline Embolization Device (ev3, Plymouth, Minn), the SILK Arterial Reconstruction Device (Balt Extrusion, Montmorency, France), and the Cardiatis Multilayer Stent (Cardiatis, Isnes, Belgium). The first two have been mainly used for the treatment of intracranial aneurysms. The aim of this study was to review the current role of FDSs in the treatment of extracranial arterial aneurysms. A systematic electronic health database search was conducted using PubMed, Ovid, Medline, and the Cochrane Database on all accessible published articles through March 2012. An additional search for abstracts presented in international congresses for vascular surgery was also performed. Full-text articles and abstracts were analyzed separately due to the heterogeneity of the data. Results of the use of FDSs in arterial aneurysms were reported in 12 full-text articles including 35 patients (26 men, age 65.4) with 38 aneurysms. The aneurysms were located in the hepatic (n = 12), splenic (n = 6), renal (n = 5), celiac (n = 4), superior mesenteric (n = 3), subclavian (n = 2), gastroduodenal (n = 1), and popliteal arteries (n = 1) and in the descending thoracic (n = 1), suprarenal (n = 1) and infrarenal aorta (n = 2). The 30-day mortality was 5.7% (2 of 35 patients). Three stent thromboses occurred (8.3%), none of them with clinical consequences. Thirty patients with 33 aneurysms and patent FDSs were monitored for an average of 9.2 months. Thrombosis occurred in 90.6%, and volume reduction was observed in 81% of the aneurysms. No branch vessel occlusion occurred. Twelve abstracts were identified, including 133 patients (mean age, 64.7 years). They included 62 peripheral, 28 visceral, and 43

    The minimally invasive approach to distal anterior cerebral artery (DACA) aneurysms has not gained much acceptance due to difficulties associated with the conventional frontal paramedian approach. The more proximal basal interhemispheric approach, however, necessitates extensive dissection of soft tissues. We describe a novel minimally invasive median supraorbital keyhole craniotomy with a basal interhemispheric approach for clipping a ruptured DACA aneurysm. A 62-year-old patient presented with subarachnoid hemorrhage. Computed tomography angiography revealed a DACA aneurysm. The surgical technique involved a keyhole craniotomy made via an eyebrow incision extending between the supraorbital notches, and flush with the anterior cranial fossa. The dura was opened at the anterior part, the falx was cut, an interhemispheric dissection was carried out, adequate proximal control was obtained, and the aneurysm neck was dissected and clipped. A relevant review of the literature was carried out. The patient recovered well, with no residual aneurysm or forehead numbness, with good cosmesis. Compared with the previously described "keyhole unilateral interhemispheric" approaches, our technique has less likelihood of encountering bridging veins; easier cisternal cerebrospinal fluid release, making it feasible even in swollen brain; better proximal vascular control; and trajectory toward the neck rather than dome. The median supraorbital keyhole approach is a minimally invasive technique sufficient for clipping most DACA aneurysms, with easier access, better proximal control, and good cosmesis.

  11. Serratia liquefaciens Infection of a Previously Excluded Popliteal Artery Aneurysm

    Directory of Open Access Journals (Sweden)

    A. Coelho

    Full Text Available : Introduction: Popliteal artery aneurysms (PAAs are rare in the general population, but they account for nearly 70% of peripheral arterial aneurysms. There are several possible surgical approaches including exclusion of the aneurysm and bypass grafting, or endoaneurysmorrhaphy and interposition of a prosthetic conduit. The outcomes following the first approach are favorable, but persistent blood flow in the aneurysm sac has been documented in up to one third of patients in the early post-operative setting. Complications from incompletely excluded aneurysms include aneurysm enlargement, local compression symptoms, and sac rupture. Notably infection of a previously excluded and bypassed PAA is rare. This is the third reported case of PAA infection after exclusion and bypass grafting and the first due to Serratia liquefaciens. Methods: Relevant medical data were collected from the hospital database. Results: This case report describes a 54 year old male patient, diagnosed with acute limb ischaemia due to a thrombosed PAA, submitted to emergency surgery with exclusion and venous bypass. A below the knee amputation was necessary 3 months later. Patient follow-up was lost until 7 years following surgical repair, when he was diagnosed with aneurysm sac infection with skin fistulisation. He had recently been diagnosed with alcoholic hepatic cirrhosis Child–Pugh Class B. The patient was successfully treated by aneurysm resection, soft tissue debridement and systemic antibiotics. Conclusion: PAA infection is a rare complication after exclusion and bypass procedures but should be considered in any patient with evidence of local or systemic infection. When a PAA infection is diagnosed, aneurysmectomy, local debridement, and intravenous antibiotic therapy are recommended. The “gold standard” method of PAA repair remains controversial. PAA excision or endoaneurysmorrhaphy avoids complications from incompletely excluded aneurysms, but is associated with

    Purpose: Evaluation of the use of covered stents in treating pseudoaneurysms of the cervical and intracranial/extradural carotid artery and determination of the periprocedural and short- to mid-term complication rate. Materials and Methods: 8 patients with 9 spontaneous dissecting aneurysms of the cervical carotid artery - 5 of which were symptomatic - plus one patient with ofthalmoplegia due to an aneurysm of the cavernous carotid artery were studied. While the latter was treated with a PTFE-covered balloon-mounted stainless steel stent (Jostent/Graftmaster), a self-expanding PTFE-covered Nitonol Stent (Symbiot) was used in all other cases. Intervention was performed with local anesthesia. Aspirin and Clopidogrel were both used as antiplatelet drugs. Clinical signs and symptoms and vascular imaging with DS, MR, CT angiography and ultrasound were recorded during patient follow-up, with a mean follow-up period of 14.6 months (4 - 30). Results: We were able to treat 8 out of 10 aneurysms (80 %) using covered stents. The aneurysms were immediately occluded and the associated stenoses of the parent vessel were eliminated. No clinically relevant complications occurred during the procedure or in the follow-up interval. In two cases, elongation of the carotid artery prevented the stent from being positioned over the aneurysm neck. These cases were shown to be stable with the use of antiplatelet drugs. Conclusion: Covered stents can be used in the treatment of pseudoaneurysms of the carotid artery as an alternative to long-term antithrombotic medication or surgery. In our study treatment was effective (80 %) and free of complications in the short- and mid-term follow-up. Possible indications, technique and the use of imaging modalities for patient follow-up are discussed. (orig.)

    Optimal treatment of intracranial aneurysms involves complete occlusion of the aneurysm with preservation of the parent artery and all of its branches. Attempts to occlude the aneurysm and preserve the parent artery may be associated with a higher level of risk than parent vessel occlusion or trapping. To evaluate our series of patients with large and giant aneurysms who underwent treatment via endovascular coiling with parent artery sacrifice or surgical ligation of the common carotid artery (CCA) and gain insight into the advantages and risks of each of these alternatives. We retrospectively reviewed all patients with aneurysms who underwent carotid sacrifice via endovascular occlusion or surgical CCA ligation during an 8-year period at our institution. Twenty-seven patients with large and giant aneurysms of the internal carotid artery underwent carotid artery sacrifice via endovascular occlusion (n = 15) or CCA ligation (n = 12). Of the patients who underwent endovascular occlusion, 3 developed groin complications, 1 developed a new sixth nerve palsy, 1 died from vasospasm related to subarachnoid hemorrhage, and 1 died secondary to rupture of an associated 3-mm anterior communicating artery aneurysm 5 days postoperatively. Of the patients undergoing CCA ligation, 1 patient developed a partial hypoglossal palsy. Clinical improvement of presenting symptoms was observed in all surviving patients regardless of the method of treatment. Complete aneurysm obliteration was documented in all patients during the initial hospital stay. The mean radiographic long-term follow-up was 14.2 months, which was available in 20 of the 25 surviving patients (80%). Complete obliteration was confirmed at follow-up in all but 2 patients with large cavernous aneurysms; 1 was initially treated with endovascular occlusion and the other with carotid ligation. Parent artery sacrifice is still a viable treatment for some complex aneurysms of the internal carotid artery. CCA ligation is a

    Blister-like aneurysms(BLA)are morphologically thin-walled fragile structures that are associated with a high risk of intraoperative rupture. BLAs presumably originate from an arterial dissection and often stem from a non-branching site on the supraclinoid segment of the internal carotid artery. We report a rare case of a patient who was successfully treated for a ruptured BLA originating from the anterior communicating artery(Acom). A 60-year-old woman presented with severe headache and loss of consciousness. Computed tomography(CT)showed diffuse subarachnoid hemorrhage(SAH), which was observed to be particularly dense in the interhemispheric fissure around the Acom. CT angiography and three dimensional-digital subtraction angiography(DSA)did not show any aneurysms along the Acom. Follow-up DSA performed on day 13 showed a small aneurysmal dilatation of the Acom, which was surgically treated via interhemispheric approach. Intraoperatively, a BLA observed to be originating from the Acom was wrapped with a piece of temporal fascia using fibrin glue. Postoperatively, this patient showed a good clinical course without re-rupture. Follow-up DSA performed 5 months after the occurrence of the SAH demonstrated disappearance of the BLA originating from the Acom. The findings in this patient strongly suggest that the pathomechanism of BLAs is attributable to an arterial dissection, which can often show morphological changes on short-term angiographic follow-up, and they demonstrate spontaneous repair. Thus, the therapeutic strategy to be utilized for the management of a BLA of the Acom should be carefully considered, because aneurysmal neck clipping or trapping can injure the Acom perforators and cause cognitive deficits. Further studies are needed to establish the optimal treatment strategy for the management of BLAs of the Acom.

    An unusual case of post-irradiation aneurysm of extracranial internal carotid artery is presented. A 70-year-old man, complaining of left cervical throbbing mass with focal pain, was admitted on February 8, 1985. It was noted, from his past history, that he had had surgery of the removal of cervical lymphnodes and that unknown dosage of irradiation had been added to the cervical region 30 years before. Left carotid angiography (on admission) demonstrated a giant aneurysm in the cervical portion of internal carotid artery. Right carotid angiography with compression of left carotid artery revealed good cross filling through anterior communicating artery. Computed tomography with contrast media showed a ring like enhanced mass, which was thought to suggest that a large part of the aneurysm was filled with intraluminal thrombosis. During 30 days of evaluation, the aneurysm grew larger and his cervical pain became untolerable. Operation, the resection of the aneurysm and the reconstruction (of circulation) with vein graft, was challenged on March 12. It was so difficult with meticulous work that the ligation of left common carotid artery was performed after all. Seven days after the operation, he suffered from the gastrointestinal bleeding, which was enough to lead him to hypovolemic shock. Thereafter, right hemiparesis and aphasia were brought about. Two months later, he died of pneumonia. On histological examination, it was demonstrated that the aneurysm communicated with the necrotic tissue and that the normal structure of the blood vessel was not observed in the aneurysmal wall and consisted of the collagenous fiber and granulated tissue. The aneurysm was interpreted as a false one.

    Spontaneous aneurysm in the axillary artery is extremely rare. The standard treatment for axillary artery aneurysm has been surgical repair, but endovascular management of select aneurysms using stent grafts has become more prevalent with the development of endoluminal technology. We report the case of a 36-year old man with a spontaneous aneurysm in the axillary artery. He experienced a tingling sensation and intermittent pain in the left upper extremity and had no history of trauma to the axilla. We performed endovascular treatment [placement of a Viabahn stent graft (W.L. Gore & Associates, Flagstaff, AZ, USA)] for a spontaneous aneurysm in the axillary artery. Following the procedure, his symptoms disappeared completely. After 6, 12 and 24 months, we carried out computed tomography angiography; all scans showed no complications. Now, the patient has no symptoms related to aneurysm in the axilla. © The Author 2014. Published by Oxford University Press on behalf of the European Association for Cardio-Thoracic Surgery.

    Full Text Available Arterial dissections are a common cause of stroke in the young (mean age 44 to 46 years. Primary lesion is a tear of the arterial intima, which promotes platelet aggregation, thrombus formation, which further produced vessel stenosis / occlusion, distal embolism or vessel wall rupture. Vertebral artery (VA dissection appear most commonly in extracranial segments V2 and V3, and could be spontaneous (with underlying predispositions or triggered by various traumatisms. Clinicaly, VA dissection produces an ischemic stroke or transient ischemic attack , preceded by local symptoms such as neck pain or headache. The diagnosis is confirmed by neurovascular imaging. Treatment of symptomatic VA dissections respect indications of treatment in ischemic strokes. Prognosis is mostly favorable in extracranial dissections. We present the case of a left VA dissection in V2 segment, produced by physical effort (swimming, which causes 2 ischemic lesions, one in the territory of the left posterior cerebral artery and the other in the territory of the left posterolateral chorroidal artery. Patient’s treatment included antiplatelet agents, statines, and an adapted physical rehabilitation program. At three months he showed significant clinical improvement with regain of autonomy and partial recanalisation at angio-MRI of the V2 segment of the dissected artery.

    The authors share herein their experience with hybrid surgical treatment of 21 patients presenting with lesions of the aortic arch and descending thoracic aorta. Aortic pathology included dissection of the thoracoabdominal aorta (n=15), a sacciform aneurysm of the aortic arch (n=5), and a spindle-shaped aneurysm of the distal portions of the aortic arch (n=1). The first stage consisted of the following operations: transposition of the left subclavian artery into the left common carotid artery (n=9; 42.8%), partial debranching (n=11; 52.5%), and total debranching (n=1; 4.7%). The second stage consisted in implantation of a stent graft: to the thoracic aorta in 18 (85.8%) cases, and to the thoracic and abdominal portions of the aorta in 3 (14.2%) cases. The most significant complications of the immediate postoperative period included acute cerebral circulation impairment (n=1) and local dissection of the ascending aorta (n=1). Type I endoleaks were observed in 4 (19%) patients, type II endoleaks in 1 (4.7%), and type III endoleaks in 1 (4.7%). The mean duration of the follow up after discharge from hospital amounted to 11.6±7.9 months. In 4 patients after 6 months the findings of the control MSCT angiography showed no significant changes of the endoleaks. 1-year patency of the shunted branches of the aortic arch amounted to 95.2%. The cumulative survival rate amounted to 95.2%.

    Two cases of ruptured aneurysms in the posterior cervical regions associated with type-1 neurofibromatosis treated by transcatheter embolization are reported. Patients presented with acute onset of swelling and pain in the affected areas. Emergently performed contrast-enhanced CT demonstrated aneurysms and large hematomas widespread in the posterior cervical regions. Angiography revealed aneurysms and extravasations of the occipital artery. Patients were successfully treated by percutaneous transcatheter arterial microcoil embolization. Transcatheter arterial embolization therapy was found to be an effective method for treating aneurysmal rupture in the posterior cervical regions occurring in association with type-1 neurofibromatosis. A literature review revealed that rupture of an occipital arterial aneurysm, in the setting of neurofibromatosis type 1, has not been reported previously.

    A 33-year-old woman with an anomalous left coronary artery arising from the pulmonary artery who had undergone Takeuchi repair at age 7 years presented for evaluation. The Takeuchi procedure creates an aortopulmonary window and an intrapulmonary tunnel that baffles the left coronary artery to the aorta. A mediastinal mass was identified as a giant aneurysm of the left coronary artery resulting in compression of the pulmonary artery and left upper pulmonary vein. The patient underwent open repair with patch closure at the aortic entrance of the left coronary Takeuchi repair and resection and evacuation of the aneurysm. A saphenous vein graft to the left anterior descending artery was performed. Postoperative echocardiography demonstrated normal left ventricular function. This is the first reported case of giant aneurysm formation after Takeuchi repair. The reported complications have included the development of pulmonary artery stenosis at the intrapulmonary baffle, baffle leak, decreased left ventricular function, and mitral regurgitation. In conclusion, late complications of the Takeuchi procedure are common, underscoring the importance of lifelong follow-up at a center with experience in treating coronary anomalies.

    CrossFit is a high-intensity strength and conditioning program that has gained popularity over the past decade. Potential injuries associated with CrossFit training have been suggested in past reports. We report three cases of cervical carotid dissection that are associated with CrossFit workouts. Patient 1 suffered a distal cervical internal carotid artery (ICA) dissection near the skull base and a small infarct in Wernicke's area. He was placed on anticoagulation and on follow-up has near complete recovery. Patient 2 suffered a proximal cervical ICA dissection that led to arterial occlusion and recurrent middle cerebral artery territory infarcts and significant neurological sequelae. Patient 3 had a skull base ICA dissection that led to a partial Horner's syndrome but no cerebral infarct. While direct causality cannot be proven, intense CrossFit workouts may have led to the ICA dissections in these patients.

    The authors retrospectively analyzed early and late results of surgical treatment for 79 Marfan patients with aneurysms and dissection of the proximal aorta. From September 1979 to February 1996, 79 patients with Marfan syndrome underwent aortic root replacement using composite grafts (n=68, Bentall-technique 63, button-technique 5), and ascending aortic replacement with a valve-sparing procedure (n=11). There were 12 patients (15.2%) who simultaneously received partial or total arch replacement. 55 patients (69.6%) were male, and 24 female (30.4%). The average age was 33.8 years. Forty-one patient (51.9%) had non-dissecting aneurysms while the remaining 38 patients suffered from either acute (24.0%) or chronic aortic dissection (24.0%). The aortic valve was involved in 97.5% of all cases. The total early mortality (valve-sparing operation and in those with chronic aortic dissection. The follow-up rate was 98.7%. During a mean follow-up of 68+/-25 months 10 patients (13.3%) died and cardiac complications were a common cause of the late deaths. There was no late mortality in the valve-sparing operations during a mean follow-up period of 8+/-6 months, however, 1 required valve replacement. 19 (25.3%) of the 75 patients surviving late have undergone 25 secondary operations on the cardiovascular system. Reoperations at aortic sites distant from the original were much more frequent after primary repair for acute and chronic dissection when compared to non-dissecting aneurysms (pMarfan-patients with non-dissecting and dissecting aneurysms of the aortic root. Our early experience in 11 patients with valve-sparing procedures indicated that this,variant may be the better choice in selected patients.

    Objective: To discuss the standardized clinical nursing measures for patients receiving endovascular treatment of renal artery aneurysms. Methods: The clinical data of 9 patients with renal artery aneurysm, who were admitted to authors' hospital during the period from Jan. 2010 to Aug. 2011 and received endovascular treatment, were retrospectively analyzed. The related nursing points as well as the received endovascular. Results: A total of 9 cases with renal artery aneurysm were treated nursing measures were summarized. Results: A total of 9 cases with renal artery aneurysm were with interventional management, including embolization (n = 6), stent implantation (n = 2) and stent implantation together with coil embolization (n = 1). The mean hospitalization time was (10±2) days. Postoperative retention of urine was observed in one patient and postoperative retroperitoneal hemorrhage occurred in another patient. Neither nursing-related nor operation-related complications occurred. Conclusion: Standardized perioperative nursing care for patients with renal artery aneurysm can surely help enhance the patient's tolerance to the surgery, and effectively prevent the complications.

    We report a rare case of aneurysm of splenic artery arising anomalously from the superior mesenteric artery (SMA). The aneurysm was treated successfully by coil embolization of the splenic artery distal to aneurysm and then deploying a stent graft in the SMA. A combination of stent graft and coil embolization for the treatment of aberrant splenic artery aneurysm has been reported only once. We describe the imaging findings and the endovascular procedure in this patient.

    Spontaneous coronary artery dissection (SCAD) remains an infrequent and elusive clinical entity of unknown etiology. However, our knowledge of SCAD has been significantly enriched in recent years. Large and prospective contemporary series have increased the interest in this disease with fewer patients misdiagnosed and a growing number of cases recognized in daily clinical practice. Classically, SCAD was thought to present mainly in young women without traditional atherosclerotic risk factors but, actually, most patients are middle-aged and are not free from coronary risk factors. A high number of associated conditions have been reported. Of these, fibromuscular dysplasia emerges as a major association with intriguing pathophysiological implications. Areas covered: This review aims to present a contemporary update on SCAD. We concentrate on the clinical scenario, related conditions, practical management and treatment strategies. Expert commentary: Recognition of SCAD is currently much more frequent and accurate as a result of increased clinical awareness and the widespread use of intravascular imaging techniques. Hopefully, in the near future an improvement in the management of SCAD patients will come not only from empirical evidence but also from dedicated clinical trials.

A 60-year-old female patient with a history of chronic type B aortic dissection and high-dose steroid use for Churg-Strauss syndrome developed a large 6.2 cm maximum diameter false lumen aneurysm. She underwent thoracic endovascular aortic repair from the left common carotid artery to the descending aorta to cover the proximal entry at the level of distal arch, with coil embolization of the left subclavian artery. To occlude the large false lumen from the reentry just below the level of the left renal artery ostium, a modified 32×45-mm Excluder aortic extender was deployed in the false lumen through the reentry, and a 16-mm Amplatzer Vascular Plug I was deployed in the waist of the modified Excluder aortic extender for complete occlusion. No obvious technical complication was seen. Contrast-enhanced computed tomography at 1 and 14 months revealed no endoleaks and showed complete false lumen thrombosis. The candy-plug technique using the Excluder aortic extender is feasible for occlusion of a large false lumen aneurysm in chronic aortic dissection. © The Author(s) 2016.

    Weill-Marchesani syndrome (WMS) is a rare form of acromelic dysplasia that is characterized by distinctive skeletal, ocular, and cardiovascular abnormalities. Previously described cardiac manifestations of WMS include aortic and pulmonary valve stenosis, mitral valve prolapse, mitral stenosis, and QTc prolongation. Autosomal dominant forms of WMS result from heterozygous pathogenic variants in FBN1, a gene with a well characterized role in the pathogenesis of thoracic aortic aneurysm (TAA) in the context of Marfan syndrome. In contrast, only one patient has been reported with aortic disease in WMS. Although the risk of aortic dissection from preceding TAA remains the leading cause of morbidity for individuals with Marfan syndrome, rare reports of arterial dissection in the peripheral vasculature have been described. Peripheral artery dissection has not been previously reported in other FBN1-related diseases. We describe a three generation family with FBN1-related WMS whose cardiovascular manifestations include TAA and cervical artery dissection, thus expanding the cardiovascular phenotype of WMS. Further research is required to quantify these risks and establish appropriate recommendations for cardiovascular imaging, medical management, and prophylactic surgical intervention in individuals with FBN1--related acromelic dysplasia. © 2017 Wiley Periodicals, Inc.

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction. While its etiology and pathogenesis remain not fully understood, SCAD occurs most frequently in patients at a young age and of a female gender. We report a case of SCAD in a 52-year-old healthy postmenopausal woman who developed acute myocardial infarction and subsequent ventricular aneurysm after emotional stress. This case may provide valuable insight into this rare disease and highlights the importance of psychological factors as contributing factors of SCAD in postmenopausal women with acute onset of chest pain.

    Objective The purpose of this study was to determine the outcomes of surgical clipping in patients with unruptured middle cerebral artery (MCA) aneurysms. Methods A retrospective single-center database of 125 consecutive patients with 143 small MCA aneurysms (< 10 mm) who underwent surgical clipping was reviewed from January 2007 to December 2010. Clinical outcomes were assessed based on surgery-related complications and follow-up (mean: 17 months) using the modified Rankin scale (mRS). Angiographic outcomes were evaluated by conventional angiography (N = 96) or computed tomography angiography (N = 29) at postoperative weeks 1 and 6. Results There were no cases of mortality. There were three surgery-related complications (intracranial hemorrhage, meningitis and wound infection, respectively). The hemorrhagic event caused transient neurological deficits. All patients showed good clinical outcomes during follow-up (mRS 0-1). There was angiographic evidence of complete occlusion in 137 aneurysms (95.8%), a small residual neck in three aneurysms (2.2%) and partial for three aneurysms. In the three cases with partial clipping, the decision was made preoperatively to leave the residual sac to maintain distal flow, and muscular wrapping was performed. Conclusion Our study demonstrates that surgical clipping of unruptured small MCA aneurysms yields favorable clinical and angiographic outcomes. Aneurysmal clipping can be safely recommended for patients with small unruptured MCA aneurysms. PMID:23346544

    Peripheral artery aneurysms proximal to a long-standing arteriovenous (AV) fistula can be a serious complication. It is important to be aware of this and manage it appropriately. Vascular access nurses input all data regarding patients undergoing dialysis access procedures into a securely held database prospectively. This was retrospectively reviewed to identify cases of brachial artery aneurysms over the last 3 years. In Morriston Hospital, around 200 forearm and arm AV fistulas are performed annually for vascular access in renal dialysis patients. Of these, approximately 15 (7.5%) are ligated. Three patients who had developed brachial artery aneurysms following AV fistula ligation were identified. All 3 patients had developed brachial artery aneurysms following ligation of a long-standing brachio-cephalic AV fistula. Two patients presented with pain and a pulsatile mass in the arm, and one presented with pins and needles and discoloration of fingertips. Two were managed with resection of the aneurysm and reconstruction with a reversed long saphenous vein interposition graft, the third simply required ligation of a feeding arterial branch. True aneurysm formation proximal to an AV fistula that has been ligated is a rare complication. There are several reasons for why these aneurysms develop in such patients, the most plausible one being the increase in blood flow and resistance following ligation of the AV fistula. Of note, all the patients in this study were on immunosuppressive therapy following successful renal transplantation. Vigilance by the vascular access team and nephrologists is paramount to identify those patients who may warrant further evaluation and investigation by the vascular surgeon.

    Splenic artery aneurysm is the most frequent visceral artery aneurysm and rupture of the aneurysm is associated with a high mortality rate. It is important to discriminate between a true aneurysm and a pseudoaneurysm that may be caused by pancreatitis, iatrogenic and postoperative causes, trauma and peptic ulcer disease. Multidetector-row CT angiography (MDCTA) allows detailed visualization of the vascular anatomy and may allow identification of aneurysms and pseudoaneurysms that affect the splenic artery. The objective of this article is to provide a review of the general characteristics of splenic artery aneurysms and pseudoaneurysms and to describe the findings of MDCTA

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome (ACS); its prevalence is estimated to be less than 3%. It is defined as a separation within the coronary arterial wall secondary to intramural bleeding with or without intimal tear, creating a false channel. It mainly affects young subjects, mainly women, without coronary atherosclerosis or risk factors for atherosclerosis. However, the occurrence of spontaneous dissection due to atheromatous disease is possible. We here report 2 cases of spontaneous coronary dissection, in order to discuss its pathogenesis, factors favoring its occurrence, its clinical presentation and its therapeutic management.

    This is a report on a patient of 64 years of age who was admitted to hospital as an inpatient thirteen years after desobliteration of the iliac artery with an extension plasty. He complained of irregular stools and occasional abdominal pain. Imaging methods were employed on account of a drop in the haemoglobin count, progressive renal insufficiency and a palpable tumor in the lower abdomen. These methods supplied evidence of a false aneurysm originating from the iliacal endarterectomy, combined with compression of the ureter and small intestine. Basing on the present case report, the general complex of problems in diagnosing aneurysms of the iliac artery is discussed. (orig.) [de

    Full Text Available Background. Intracranial artery dissections are rare and many controversies exist about treatment options. The aim of this study was to evaluate the efficacy and safety of the endovascular approach in patients with an intracranial dissection presenting with different symptoms. Methods. We prospectively evaluated the clinical features and treatment outcomes of 30 patients who had angiographically confirmed nontraumatic intracranial dissections over 4 years. Patients were followed up for 17 months, and their final outcomes were assessed by the modified Rankin Score (mRS and angiography. Results. Sixteen (53.3% patients had a dissection of the anterior circulation, whereas 14 (46.7% had a posterior circulation dissection. Overall, 83.3% of the patients suffered a subarachnoid hemorrhage (SAH. Grade IV Hunt and Hess score was seen in 32% of the SAH presenting cases. Parent artery occlusion (PAO with coil embolization was used in 70% of the cases. The prevalence of overall procedural complications was 23.3%, and all were completely resolved at the end of follow-up. No evidence of in-stent occlusion/stenosis or rebleeding was observed in our cases during follow-up. Angiography results improved more frequently in the PAO with coil embolization group (100% than in the stent-only-treated group (88.9% (P=0.310 and the unruptured dissection group (5/5, 100% in comparison with the group that presented with SAH (95.8% (P=0.833. Conclusion. Favorable outcomes were achieved following an endovascular approach for symptomatic ruptured or unruptured dissecting aneurysms. However, the long-term efficacy and durability of these procedures remain to be determined in a larger series.

    Cerebral mycotic or infective aneurysms are a rare complication of infectious illness, and such aneurysms of the intracavernous portion of the internal carotid artery are rare. They have been described as a consequence of cavernous sinus infection in an immunocompromised host, but not previously in a renal transplant recipient. We present such a case with serial MRI showing progression from arterial narrowing to aneurysm formation. Transcranial Doppler sonography of the middle cerebral artery showed distal asymptomatic embolisation from the aneurysm. (orig.)

    Giant coronary artery aneurysm associated with a coronary-cameral fistula is an uncommon condition. Such aneurysms are usually associated with other cardiac diseases, such as coronary atherosclerosis, and therefore might augment myocardial ischemia in adults. The main indications for surgical intervention are severe coexisting coronary artery disease, evidence of embolization, and aneurysmal enlargement or rupture. We describe a large right coronary artery aneurysm and a coronary-cameral fistula that drained into the superior vena cava. The surgical repair was successful.

    Full Text Available The rupture of an internal mammary artery (IMA aneurysm in a patient with type 1 neurofibromatosis (NF-1 is a rare but life-threatening complication requiring emergency management. A 50-year-old man with NF-1 was transferred to the emergency department of Kyungpook National University Hospital, where an IMA aneurysmal rupture and hemothorax were diagnosed and drained. The IMA aneurysmal rupture and hemothorax were successfully repaired by staged management combining endovascular treatment and subsequent video-assisted thoracoscopic surgery (VATS. The patient required cardiopulmonary cerebral resuscitation, the staged management of coil embolization, and a subsequent VATS procedure. This staged approach may be an effective therapeutic strategy in cases of IMA aneurysmal rupture.

    We report 2 cases of true uterine artery aneurysms diagnosed during pregnancy. Both cases presented with nonspecific symptoms such as urethral obstruction, minimal vaginal bleeding and lower abdominal pain in the 2nd trimester. Both aneurysms were diagnosed by color Doppler ultrasound. In the first case labor was induced at 37 + 4 weeks of gestation. However, due to sudden fetal distress and maternal abdominal pain, an emergency Caesarean section was performed during labor, and 3 liters of intra-peritoneal blood were encountered upon laparotomy, secondary to a ruptured uterine artery aneurysm. In the second case, an elective Caesarean section was scheduled at 38 + 3 weeks of gestation, and the delivery and postpartum period were uncomplicated. Albeit a rare condition, a uterine artery aneurysm should be among the differential diagnosis considered in pregnant women who present with pelvic and vaginal masses, vague bladder symptoms or radiating pelvic pain. The diagnosis is readily made by color Doppler imaging. Elective Caesarean section should be the preferred mode of delivery to avoid rupture of the aneurysm during labor. © 2016 S. Karger AG, Basel.

    A 49-year-old man complained of sudden upper abdominal pain but was not given a definitive diagnosis. The day after he was discharged, he noticed left chest pain. An in-depth electrocardiogram indicated acute myocardial infarction, and emergent coronary angiography revealed 99% stenosis of his left coronary artery. An intravascular ultrasound revealed spontaneous coronary artery dissection (SCAD), and the lesion was successfully stented. In an atherosclerosis screening, superior mesenteric artery dissection (SMAD) was confirmed, after which the lesion was successfully stented. This case suggests that SCAD and SMAD might have similar pathological backgrounds. PMID:28566599

    Cervical artery dissections involve the carotid or vertebral arteries. Although the overall incidence is low, they remain a common cause of stroke in children, young adults, and trauma patients. Symptoms such as headache, neck pain, and dizziness are commonly seen in the emergency department, but may not be apparent in the obtunded trauma patient. A missed diagnosis of cervical artery dissection can result in devastating neurological sequelae, so emergency clinicians must act quickly to recognize this event and begin treatment as soon as possible while neurological consultation is obtained. This issue reviews the evidence in applying advanced screening criteria and choosing imaging and antithrombotic treatment strategies for patients with cervical artery dissections to reduce the occurrence of ischemic stroke.

    Since the first report of an aneurysm involving the pancreaticoduodenal arteries a century ago, only 83 cases have been reported in our collective review of the English literature. Their presentation varies from indistinct abdominal pain to hemorrhagic shock, often making the diagnosis onerous. The mortality rate in this patient group has been significant, and in cases reported since 1980, the mortality rate remains at 17% (7 deaths/42 reported cases). Surgery has been, and continues to be, the cornerstone of therapy, with an incumbent mortality rate of 19% (5 deaths/26 patients treated surgically since 1980). This case report and 100-year review of the literature describes the causes, natural history, and historic management of pancreaticoduodenal artery aneurysms. Most importantly, it demonstrates the use of angiographic embolization in the definitive management of these aneurysms with no mortality.

    Unruptured anterior inferior cerebellar artery (AICA) aneurysms are rare but potentially lethal cerebellopontine angle (CPA) lesions that may be misdiagnosed as vestibular schwannomas when they present with vestibulo-cochlear symptoms. We report two cases of unruptured but symptomatic AICA aneurysms initially referred to us as atypical vestibular schwannomas requiring surgery. Two discriminant MR features are described. One patient refused treatment. The other was successfully treated by coil occlusion. Caution is advised before suspecting a CPA mass to be a purely extra-canalicular schwannoma, given its extreme rarity. Deafness and cerebellar ischemia may be prevented if AICA aneurysms are correctly identified preoperatively. In the absence of specific arterial imaging, two MR features may distinguish them from vestibular schwannomas: (1) the absence of internal auditory canal enlargement and (2) the "blurry dot sign," representing blood flow artefacts on pre- and postcontrast studies.

    Full Text Available BACKGROUND AND PURPOSE: Hemodynamic factors are commonly believed to play an important role in the pathogenesis, progression, and rupture of cerebral aneurysms. In this study, we aimed to identify significant hemodynamic and morphological parameters that discriminate intracranial aneurysm rupture status using 3-dimensional-angiography and computational fluid dynamics technology. MATERIALS AND METHODS: 3D-DSA was performed in 8 patients with mirror posterior communicating artery aneurysms (Pcom-MANs. Each pair was divided into ruptured and unruptured groups. Five morphological and three hemodynamic parameters were evaluated for significance with respect to rupture. RESULTS: The normalized mean wall shear stress (WSS of the aneurysm sac in the ruptured group was significantly lower than that in the unruptured group (0.52±0.20 versus 0.81±0.21, P = .012. The percentage of the low WSS area in the ruptured group was higher than that in the unruptured group (4.11±4.66% versus 0.02±0.06%, P = .018. The AR was 1.04±0.21 in the ruptured group, which was significantly higher than 0.70±0.17 in the unruptured group (P = .012. By contrast, parameters that had no significant differences between the two groups were OSI (P = .674, aneurysm size (P = .327, size ratio (P = .779, vessel angle (P = 1.000 and aneurysm inclination angle (P = 1.000. CONCLUSIONS: Pcom-MANs may be a useful disease model to investigate possible causes of aneurysm rupture. The ruptured aneurysms manifested lower WSS, higher percentage of low WSS area, and higher AR, compared with the unruptured one. And hemodynamics is as important as morphology in discriminating aneurysm rupture status.

    Although a number of studies have assessed the surgical treatment of paraclinoid-segment carotid artery aneurysms and resulting visual complications, less attention has been given to the results with respect to the superior hypophyseal artery (SHA). The authors evaluated the relationship between the aneurysm, the SHA itself, and postoperative visual function in patients with ruptured and unruptured SHA aneurysms. From January 1991 through December 2013, 181 patients with 190 paraclinoid carotid artery aneurysms received treatment at Shinshu University Hospital and its affiliated hospitals. The authors retrospectively analyzed charts, operative records, operative videos, and neuroimaging findings for these patients with or without postoperative visual complications. The authors identified 72 SHA aneurysms in 70 patients (mean age 58 years). Of 69 patients (1 patient died) evaluated, postoperative visual complications occurred in 9 (13.0%). Although the aneurysm size and SHA sacrifice did not lead to postoperative visual impairment, simultaneous treatment of bilateral aneurysms was a risk factor for postoperative visual complications. Unilateral SHA impairment may be safe (i.e., it may not induce ischemia of the optic pathway) for many, but not all, patients with SHA aneurysm.

    Endovascular coiling is widely used for many cerebral aneurysms; however, in cases of middle cerebral artery bifurcation (MCBIF) aneurysms, it is associated with a higher incidence of unfavorable outcomes compared to microsurgical clippings. In this retrospective study, we aimed to investigate the outcomes of microsurgical clipping for unruptured MCBIF aneurysms and determine the ideal clipping methods for different aneurysm subtypes. From January 2011 to December 2013, 203 aneurysms with saccular shape (<25 mm) were treated by an experienced neurosurgeon. Depending on the involvement of the aneurysmal thin wall, the aneurysm neck was classified as follows: subtype I, limited bifurcation; subtype II, progressed to M1 trunk; subtype III, progressed to M2 trunk; subtype IV, progressed to M1 and one M2 trunk; and subtype V, progressed to M1 and two M2 trunks. The clipping methods included simple, sliding, interlocking, or mixed approaches. Aneurysm clippings were accomplished without any morbidity in all cases, and seven cases had a minimal neck remnant. The following clipping methods were predominantly used: subtype I, simple (90.2%) and sliding (8.8%) (mean = 1.2 clips); subtype II, interlocking (51.4%), sliding (30.0%), mixed (15.7%), and simple (2.9%) (2.4 clips); subtype III, simple (57.5%) and sliding (42.5%) (1.5 clips); subtype IV, interlocking (64.3%) (2.1 clips), simple (10.7%), sliding (14.3%), and mixed (10.7%); and subtype V, interlocking (50.0%), sliding (35.7%), and mixed (14.3%) methods with multiple clips (2.8 clips). If an appropriate clipping method is selected according to the neck classification, satisfactory surgical obliteration can be achieved for unruptured MCBIF aneurysms without morbidity.

    Our objective was to evaluate the association between fluoroquinolone use and aortic dissection or aortic aneurysm in a systematic review and meta-analysis. We searched Medline, Embase, and Scopus from inception to February 15, 2017. We selected controlled studies for inclusion if they reported data on aortic dissection and aortic aneurysm associated with fluoroquinolones exposure versus no exposure. Data were extracted by 2 independent reviewers, with disagreements resolved through further discussion. We assessed the quality of studies using the Newcastle-Ottawa Scale for observational studies and the strength of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. The odds ratios (ORs) from observational studies were pooled using the fixed-effect inverse variance method, and statistical heterogeneity was assessed using the I 2 statistic. After a review of 714 citations, we included 2 observational studies in the meta-analysis. Current use of fluoroquinolones was associated with a statistically significantly increased risk of aortic dissection (OR, 2.79; 95% confidence interval [CI], 2.31-3.37; I 2  = 0%) and aortic aneurysm (OR, 2.25; 95% CI, 2.03-2.49; I 2  = 0%) in a fixed-effects meta-analysis. The unadjusted OR estimates and sensitivity analysis using a random-effects model showed similar results. We rated the strength of evidence to be of moderate quality. The number needed to treat to harm for aortic aneurysm for elderly patients aged more than 65 years who were current users of fluoroquinolones was estimated to be 618 (95% CI, 518-749). Evidence from a small number of studies suggests that exposure to fluoroquinolones is consistently associated with a small but significantly increased risk of aortic dissection and aortic aneurysm.

    Aneurysms of the anterior pontine segment of the anterior-inferior cerebellar artery (AICA) are uncommon. Their treatment is challenging because critical neurovascular structures are adjacent to it and the available surgical corridors are narrow and deep. Although endoscopic endonasal approaches are accepted for treating midline skull base lesions, their role in the treatment vascular lesions remains undefined. The present study is aimed to assess the anatomic feasibility of the endoscopic endonasal transclival (EET) approach for treating anterior pontine AICA aneurysms and compare it with the subtemporal anterior transpetrosal (SAT) approach. Twelve cadaveric specimens were prepared for surgical simulation. The AICAs were exposed using both EET and SAT approaches. Surgical window area and the length of the exposed artery were measured. The distance from the origin of the artery to the clip applied for proximal control was measured. The number of AICA perforators exposed and the anatomic features of each AICA were recorded. The EET approach provided a wider surgical window area compared with the SAT (P AICA perforators were visualized using the EET approach (P AICA, an aneurysm clip could be applied closer to the origin of AICA using EET (0.2 ± 0.42 mm) compared with SAT (6.26 ± 3.4 mm) (P AICA aneurysms using the EET approach is feasible. Compared with SAT, the EET approach provides advantages in surgical window area, ensuring proximal control before aneurysm dissection, visualization of perforating branches, and better proximal control.

    A 65-year-old woman who had been diagnosed as having microscopic polyangiitis developed sudden abdominal pain and entered a state of shock. Abdominal CT showed massive hemoperitoneum, and emergent angiography revealed a ruptured splenic artery aneurysm. After direct catheterization attempts failed due to tortuous vessels and angiospasm, transcatheter arterial embolization using an n-butyl cyanoacrylate (NBCA)-lipiodol mixture was successfully performed. Fifty days later, the patient developed sudden abdominal pain again. Repeated angiography demonstrated recanalization of the splenic artery and splenic artery aneurysm. This time, the recanalized aneurysm was embolized using metallic coils with the isolation method. Physicians should keep in mind that recanalization can occur after transcatheter arterial embolization using N-butyl cyanoacrylate, which has been used as a permanent embolic agent.

  7. Transcarotid Artery Endovascular Reconstruction of the Aortic Arch by Modified Bifurcated Stent Graft for Stanford Type A Dissection

    2007-10-01

    Full Text Available A 40-year-old man with Stanford type B dissection underwent his first endovascular repair (EVAR in April 2004 by Talent thoracic stent graft. He had an uncomplicated recovery and maintained good blood pressure control. However, a new retrograde dissection appeared in September 2004. The new dissection involved his aortic arch and ascending thoracic aorta to the opening of the coronary arteries. To reconstruct the aortic arch, bypasses between the right common carotid artery (RCCA, left common carotid artery and left subclavian artery were performed before endovascular repair. A modified bifurcated Talent stent graft was deployed from the RCCA to the ascending thoracic aorta with a long limb in the innominate artery and a short limb in the aortic arch. A further two pieces of graft were deployed via the common femoral artery. The ascending thoracic aorta and aortic arch were reconstructed completely by the bifurcated stent graft. The final angiography confirmed that there was good stent graft configuration, normal blood flow, and stable haemodynamics. No endoleak or other major complications were encountered. This result indicated that it is possible to reconstruct the aortic arch with a bifurcated stent graft and could be a new endovascular repair model for complex thoracic aortic aneurysm and dissection.

    Full Text Available Traumatic carotid artery dissection may appear after blunt head or neck trauma. Patients were either asymptomatic or clinically symptoms may include loss of consciousness, hemiparesis, aphasia and Horner syndrome, these typically occurring after an interval of hours to days. Patients were either asymptomatic or clinically symptoms may include headache, transient ischemic attack, stroke, Horner Syndrome and loss of consciousness, these typically occurring after an interval of hours to days. Prognosis is good if an early diagnosis and treatment were established. As cerebral ischemia and neurological deficits may develop in subsequent periods, it is essential that the carotid artery dissection should be kept in mind for possible cases in order to evaluate and diagnose it properly. In this article, we present a case of internal carotid artery dissection including diagnostic neuroimaging, which occurred after 6 hours of blunt trauma and subsequent cerebral infarction following a car accident. Clinical features, neuroradiological diagnostic methods and treatments options are discussed with the relevant literature

    Full Text Available INTRODUCTION: Cervicocranial artery dissections account for 25% of ischaemic strokes in young adults. Numerous risk factors that can damage the structure of the vessel walls have been identified. Dissections can present with various forms of stroke, and are diagnosed using magnetic resonance angiography or digital subtraction angiography. In our study, we aimed to evaluate the clinical and radiological characteristics of cervicocranial artery dissections. METHODS: We retrospectively analysed 45 patients, twenty-nine (64% males and 16 (36% females, pre-diagnosed with dissection in the Angiography Unit of the Bakirkoy Mazhar Osman State Training and Research Hospital for Psychiatric and Neurological Diseases. The mean age of females and males was 35 and 39 years, respectively. RESULTS: Forty-one (91% patients presented with transient ischaemic attack and/or ischaemic stroke. Isolated 12th nerve paralysis was found in one patient, and headache was the only symptom in another. Digital subtraction angiography was performed in all the patients, and bilateral dissection was detected in six patients. From the angiography results, three different types of vessel pathologies were detected: 1 long-segment irregularities (65%, 2 tapering occlusion (35% and 3 pseudoaneurysm (16%. Radiological follow-up was done for 19 (42% patients; eight of them completely recovered showing normal imaging findings. DISCUSSION AND CONCLUSION: Dissection can present with a broad clinical spectrum, and it should be suspected in cases with unusual neck movement and mild-to-severe trauma. Digital subtraction angiography is still the best modality for the diagnosis of dissection.

    Intracranial lipomas are rare congenital malformations that can often be seen in association with other brain malformations; agenesis or dysgenesis of the corpus callosum is the most frequently associated brain anomaly. They are usually pericallosal asymptomatic midline lesions. Intracranial lipomas associated with a non-contiguous cerebral aneurysm are extremely rare. We report an infant with partial agenesis of the corpus callosum and pericallosal lipoma associated with cerebral haemorrhage due to a distal middle cerebral artery aneurysm. Such an association is probably not fortuitous and could suggest a pathogenic relationship. (orig.)

    We report a rare case of bilateral hypoplasia of the internal carotid arteries with an associated aneurysm of the basilar tip, studied by CT angiography, MR angiography and digital angiography. The patient became symptomatic with an episode of loss of consciousness, likely due to reduced blood perfusion. The other 20 reported cases of bilateral carotid hypoplasia (only four of which with an associated aneurysm) are reviewed. The findings of noninvasive procedures (including narrowing of the carotid canals on CT) may lead to a correct diagnosis before angiography is performed; they may also help to differentiate angiographic narrowing of the hypoplastic internal carotids from the string sign often observed in some acquired conditions.

    Full Text Available Splenic artery aneurysms (SAAs are the third most common abdominal aneurysm. Endovascular treatment of SAAs is preferred, and coiling is the most commonly used technique. Ruptured giant (>5 cm SAAs are usually treated with open surgery including splenectomy. We present a rare case of a ruptured 15-cm giant SAA in an 84-year-old woman treated successfully with emergency endovascular coiling. To our knowledge, this is one of the few reports of emergency endovascular treatment for ruptured giant SAA.

    A 36-year-old man with a recent history of surgery for an aortic valve ascending aortic aneurysm was admitted for non-ST-elevation myocardial infarction. Cardiac magnetic resonance imaging showed a limited necrotic lesion in the anterior wall. Coronary angiography showed no significant stenosis, but a mild distal dynamic tortuosity was seen on the left anterior descending artery. Optical coherence tomography analysis confirmed the absence of any significant atherosclerotic infiltration but revealed the presence of a localized short arterial dissection within the kinked zone. The patient was managed with a conservative medical approach. The subsequent evolution was uneventful. Copyright © 2015 Canadian Cardiovascular Society. Published by Elsevier Inc.

    Spontaneous coronary artery dissection (SCAD) is an infrequent cause of acute coronary syndrome and is often underdiagnosed. Intramural hematoma is the most frequent angiographic presentation and is a challenging diagnosis that may require intravascular imaging techniques to confirm it and guide treatment. It affects mostly young women without coronary risk factors and is usually associated with fibromuscular dysplasia. SCAD has an underlying disease in 80% of patients. A SMAD3 mutation has been linked to aneurysm-osteoarthritis syndrome and has been identified as a cause of familial thoracic aortic aneurysm and dissection. The first reported case, to our knowledge, of a SMAD3 mutation underlying SCAD is described here. Copyright © 2016 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

    Splanchnic artery aneurysms are very rare in children. We report a 10-year-old girl with a large atraumatic ruptured superior mesenteric artery aneurysm that was considered inoperable. She was ultimately treated with two percutaneous US-guided thrombin injections, which led to complete occlusion of the aneurysm. The aetiology of the aneurysm remained unclear, but a family history was suggestive of a congenital connective tissue disease such as Ehlers-Danlos syndrome subtype IV. (orig.)

    Full Text Available Abstract Background Visceral artery aneurysms (VAA, although uncommon, are increasingly being detected. We describe a case of spontaneous retroperitoneal hemorrhage from a ruptured IMA aneurysm associated with stenosis of the superior mesenteric artery (SMA and celiac trunk, successfully treated with surgery. Methods A 65-year-old man presented with abdominal pain and hypovolemic shock. Abdominal CT scan showed an aneurysm of the inferior mesenteric artery with retroperitoneal hematoma. In addition, an obstructive disease of the superior mesenteric artery and celiac axis was observed. Results Upon emergency laparotomy a ruptured inferior mesenteric artery aneurysm was detected. The aneurysm was excised and the artery reconstructed by end-to-end anastomosis. Conclusions This report discusses the etiology, presentation, diagnosis and case management of inferior mesenteric artery aneurysms.

    This study comprised 16 patients with aortic dissecting aneurysm who were admitted to Seoul National University Hospital from May 1984 to January 1987. CT findings in 16 cases of aortic dissecting aneurysm were correlated with angiographic findings retrospectively. The results were analysed. 1. Number of male was 11 and that of female was 5. Male patients in fifties were most common and 4 in number. 13 patients had hypertension or history of hypertension among 14 patients. There were one case of Marfan's syndrome, preeclampsia and Takayasu's arteritis respectively. 2. There were 5 cases of DeBakey type I, 1 case of type II and 9 cases of types III dissecting aneurysm. Type III was most common. 3. CT confirmed as superior vena cava which was not identified whether it was superior vena cava or unopacified false lumen by angiography in one case. Regarding distal extent, authors defined A whose extent was proximal to diaphragm and B beyond it for convenience sake. There was one false negative case in CT among 16 cases which was diagnosed as dissecting aneurysm type IIIB by angiography and confirmed as type III surgically. One case was diagnosed as type IB by CT and as type IIIB by angiography and confirmed as type I surgically. Extent was more accurate in CT than angiography. One case was diagnosed as type II by CT but misdiagnosed as right atrial tumor by angiography. 4. Diagnostic sensitivities of CT and angiography in this study were 94% (15/16) respectively. CT was more advantageous in hemothorax, hemopericardium, hemomediastinum, unopacified false lumen, aortic wall calcification and getting information about mediastinum. In angiography aortic regurgitation and tear site and involvement of abdominal vessels could be observed

    Aneurysms affecting the aorta are a common condition associated with high mortality as a result of aortic dissection or rupture. Investigations of the pathogenic mechanisms involved in syndromic types of thoracic aortic aneurysms, such as Marfan and Loeys-Dietz syndromes, have revealed an important contribution of disturbed transforming growth factor (TGF)-β signaling. This study sought to discover a novel gene causing syndromic aortic aneurysms in order to unravel the underlying pathogenesis. We combined genome-wide linkage analysis, exome sequencing, and candidate gene Sanger sequencing in a total of 470 index cases with thoracic aortic aneurysms. Extensive cardiological examination, including physical examination, electrocardiography, and transthoracic echocardiography was performed. In adults, imaging of the entire aorta using computed tomography or magnetic resonance imaging was done. Here, we report on 43 patients from 11 families with syndromic presentations of aortic aneurysms caused by TGFB3 mutations. We demonstrate that TGFB3 mutations are associated with significant cardiovascular involvement, including thoracic/abdominal aortic aneurysm and dissection, and mitral valve disease. Other systemic features overlap clinically with Loeys-Dietz, Shprintzen-Goldberg, and Marfan syndromes, including cleft palate, bifid uvula, skeletal overgrowth, cervical spine instability and clubfoot deformity. In line with previous observations in aortic wall tissues of patients with mutations in effectors of TGF-β signaling (TGFBR1/2, SMAD3, and TGFB2), we confirm a paradoxical up-regulation of both canonical and noncanonical TGF-β signaling in association with up-regulation of the expression of TGF-β ligands. Our findings emphasize the broad clinical variability associated with TGFB3 mutations and highlight the importance of early recognition of the disease because of high cardiovascular risk.

    Vertebrobasilar (VB) intracranial dissecting aneurysms (IDAs) pose difficult therapeutic issues and are especially among the most difficult to manage surgically. There are, however, some cases where selective aneurysm obliteration by endovascular approach is impossible or is associated with an unacceptable risk of morbidity. This is particularly true when the aneurysm is dissecting, giant, or has a large neck. In such cases, surgical treatment may be the only alternative. Optimal management of these lesions is therefore challenging and treatment decisions have to be made on a case-by-case basis. Ideal treatment should be a complete surgical excision of the lesion; however, this procedure might only be possible after distal and proximal vessel wall occlusion which might not be tolerated by the patient depending on the location of the aneurysm. Therefore, formulation of recommendations concerning the surgical strategy remains still difficult due to inconsistency of surgical outcomes. The literature describing surgical strategy of VB IDAs is varying in quality and content, and many studies deal with only a few patients. In the presented review, the authors summarize the current knowledge on the incidence, pathogenesis, clinical presentation, and diagnostic procedures with special emphasis on surgical treatment of IDAs in posterior circulation.

    Congenital coronary artery fistula is an uncommon heart anomaly involving the coronary arteries. We report here a case of a 4-year-old boy who had a coronary fistula from the right coronary artery to the right ventricle, with a coronary aneurysm. He was asymptomatic, but the calculated ratio of pulmonary blood flow to systemic blood flow was shown to be high [pulmonary flow (Qp)/systemic flow(Qs)=1.78]. The coronary angiography showed that the right coronary artery was dilated beginning at the ostium and had an aneurysm at the acute marginal portion. A large spherical aneurysm approximately 20 mm in diameter was found to have been connected with coronary fistula opening into the right ventricle. Surgical repair by closure of the fistula under direct vision, partial resection and suture closure of the aneurysm was performed. Plication of the proximal portion of the right coronary artery was not performed, and the diffusely dilated artery was left untouched. After this operation, he recovered well under anticoagulant treatment with warfarin and aspirin. Postoperative angiography was performed 17 months after the surgery to evaluate morphological changes in the coronary artery. The angiography confirmed the closure of the fistula and the regression of coronary artery dilatation.

    Full Text Available Background and Purpose. Spontaneous vertebral artery dissection (SVAD is an important reason for posterior-circulation-ischemic stroke in the young and middle-aged population. Although some previous reports reveal a favorable outcome with conservative therapy, it is still controversial in the treatment of SVAD in some specific patients. Herein, we present our 10 years of clinical experience for SVAD at this location. Material and Methods. 20 patients with 20 SVADs in V2 and V3 segments were retrospectively studied. Clinical manifestations and imageology materials were collected and analyzed. All the patients underwent anticoagulation except for one patient because of contraindication. 14 patients underwent Wingspan stents implantation with general anesthesia. Results. In our sample, ischemia (infarction or transient ischemic attack, TIA was found in all the patients. Angiographic stenosis and dissection aneurysm were the most common findings in the segments mentioned above. 19 of the patients (95% got the excellent imageological and clinical outcomes. Conclusions. According to our experience in this group, although anticoagulation is effective in vertebral artery dissection, interventional therapy for SVADs in V2 and/or V3 segments is preferred in some specific patients. Stent with higher radial supporting and flexibility, such as Wingspan stent, is suggested.

    The impact of statin therapy on cardiovascular outcome in coronary artery disease (CAD) patients with aortic aneurysm or dissection (AD) is still unclear. The aim of this study was to elucidate the effect of statins at discharge to improve outcomes in CAD patients with AD. Among 14,834 consecutive patients who underwent first coronary revascularization in the CREDO-Kyoto PCI/CABG registry, we identified 699 patients (4.7%) with AD. The primary outcome measure was defined as a composite of all-cause death, myocardial infarction, and stroke. The effect of statin therapy was assessed by a Cox proportional hazards model incorporating clinically relevant factors. The risk for the primary outcome measure was significantly higher in patients with AD (adjusted hazard ratio [HR], 1.43; 95% confidence interval [CI], 1.23-1.66; P aneurysm repair, and only 274 patients (39%) were treated with statins at discharge. Patients treated with statins were younger, had higher body mass index, and were more often treated with percutaneous coronary intervention. Heart failure, anemia, and hemodialysis were more prevalent in patients treated without statins. In patients without AD, 7014 patients (50%) were treated with statins. Patients treated with statins were younger and had higher body mass index, and more patients were treated for CAD due to myocardial infarction. Heart failure, prior stroke, hemodialysis, anemia, and malignant disease were more prevalent in patients treated without statins. The use of statins was associated with lower risk for the primary outcome measure in patients with AD (adjusted HR, 0.71; 95% CI, 0.51-0.99; P = .045) as well as in patients without AD (adjusted HR, 0.79; 95% CI, 0.73-0.85; P < .0001). The effect size of statin use was similar between the patients with AD and those without AD (P interaction = .69). CAD patients with AD had significantly higher long-term risk for cardiovascular events. Statin therapy was associated with lower risk for

    Isolated iliac artery aneurysm is a rare pathology that is often asymptomatic for long periods; this late diagnosis exposes patients to a high risk of death following aneurysm rupture. The aim of this study was to establish the most suitable diagnostic approach, the correct indications for treatment, and the most appropriate tactics and surgical technique. Twenty-eight patients were observed over 13 years. Aneurysmal involvement was unilateral in 22 cases and bilateral in the remaining 6 patients. Preoperative diagnostic tests included eco-colour Doppler (ECD) and angio-CT in all cases, with angio-MR and angiography as more selective procedures. Seventeen patients underwent conventional open surgery with prosthetic replacement of the aneurysmatic tract, 7 patients were treated using endovascular exclusion, and lastly 4 were monitored over time. There was no perioperative mortality for either treatment. During the postoperative period following conventional open surgery, complications included one case of severe respiratory failure, one microembolism of the lower limb, and 2 periprosthetic hematoma. During the follow-up, we observed one pseudo-aneurysm, 3 cases of retrograde ejaculation and one patient with erectile dysfunction after traditional surgery; there was one minor endoleak after endovascular exclusion. Our experience suggests that ECD is a useful method for arriving at an early diagnosis, while angio-CT imaging is essential for a correct preoperative study. Aneurysms with a diameter equal or greater than 3 cm or that present annual increases in excess of 5 mm represent a correct indication for treatment. Conventional open surgery is the treatment of choice for young patients in good general conditions. Endovascular exclusion is indicated when the patient's clinical conditions contraindicate open surgery and the morphology of the aneurysmal arterial district allows the endoprosthesis to be safely implanted.

    Male, 74 FINAL DIAGNOSIS: Abdominal aortic aneurysm (AAA) Symptoms: Palpable abdominal mass Medication: - Clinical Procedure: Abdominal aortic aneurysm repair Specialty: Surgery. Rare disease. Coronary artery disease is common in elderly patients with abdominal aortic aneurysms. Here we report a case of the combination of surgical repair for abdominal aortic aneurysm and off-pump and minimally invasive coronary artery bypass surgery. A 74-year-old man who presented at our clinic with chest pain was diagnosed with an abdominal aortic aneurysm. His medical history included right coronary artery stenting. Physical examination revealed a pulsatile abdominal mass on the left side and palpable peripheral pulses. Computed tomography scans showed an infrarenal abdominal aneurysm with a 61-mm enlargement. Coronary angiography revealed 80% stenosis in the stent within the right coronary artery and 20% stenosis in the left main coronary artery. The patient underwent elective coronary artery bypass grafting and abdominal aortic aneurysm repair. Abdominal aortic aneurysm repair and transdiaphragmatic off-pump and minimal invasive coronary artery bypass grafting with right gastroepiploic artery were performed simultaneously in a single surgery. We report this case to emphasize the safety and effectiveness of transdiaphragmatic off-pump and minimally invasive coronary artery bypass surgery with abdominal aortic aneurysm repair. This combined approach shortens hospital stay and decreases cost.

    Patil, Akshay; Menon, Girish R.; Nair, Suresh

    2013-01-01

    Aneurysms generally present with bleed and epileptogenic aneurysms are rare. Unruptured epilpetogenic anterior communicating artery aneurysms are extremely rare and anecdotal. We present three patients with unruptured anterior communicating artery aneurysms who presented with seizures and were surgically managed. Seizure might be related to the large size, presence of thrombus, microbleeds and surrounding gliosis. We suggest that large thrombosed anterior communicating artery aneurysms should be considered in the differential diagnosis of patients presenting with late onset of seizure and having a suprasellar lesion on imaging. Surgical clipping offers a fair chance of seizure freedom in selected patients. PMID:24403964

    Although open repair is the standard surgical option for dissecting descending thoracic aneurysms (DTAs) and thoraco-abdominal aorta aneurysms (TAAAs), it remains a significant challenge with considerable perioperative morbidity and mortality. We retrospectively analysed early and late outcomes of open repair for these aortic aneurysms. Early and late outcomes were investigated for 223 consecutive patients who underwent open repair for dissecting DTA or TAAA between January 2003 and December 2014 (mean age 55 ± 16 years). The basic strategy for open surgery comprised liberal use of deep hypothermia and aggressive preservation or reattachment of intercostal arteries, i.e. donor arteries for the artery of Adamkiewicz. Deep hypothermia was used in 150 (67.3%) patients. The overall in-hospital mortality rate was 3.6% and 1.5% for elective cases. The rates of spinal cord ischaemic injury and stroke were 3.1% and 4.5%, respectively. During follow-up (mean 63 ± 40 months), overall 5-year survival rates was 89.2 ± 2.4% and 91.3 ± 2.8% and 86.3 ± 4.1% for DTA and TAAA, respectively. Five- and 10-year rates of freedom from aortic events, defined as surgery for initial operation-related events or for downstream aortic dilation, were 89.1 ± 3.5% and 68.2 ± 7.8% for DTA and 100% and 96.6 ± 3.4% for TAAA, respectively (P < 0.01). Our approach in treating this aortic pathology showed favourable early and long-term outcomes with acceptable neurological complication rates. More careful follow-up is necessary in patients with DTA repair, because downstream aortic enlargement occurs in some patients. © The Author 2017.

    Rupture of isolated posterior spinal artery (PSA) aneurysms is a rare cause of subarachnoid hemorrhage (SAH) that presents unique diagnostic challenges owing to a nuanced clinical presentation. Here, we report on the diagnosis and management of the first known case of an isolated PSA aneurysm in the context of leukocytoclastic vasculitis. A 53-year-old male presented to an outside institution with acute bilateral lower extremity paralysis 9 days after admission for recurrent cellulitis. Early magnetic resonance imaging was read as negative and repeat imaging 15 days after presentation revealed SAH and a compressive spinal subdural hematoma. Angiography identified a PSA aneurysm at T9, as well as other areas suspicious for inflammatory or post-hemorrhagic reactive changes. The patient underwent a multilevel laminectomy for clot evacuation and aneurysm resection to prevent future hemorrhage and to establish a diagnosis. The postoperative course was complicated by medical issues and led to the diagnosis of leukocytoclastic vasculitis that may have predisposed the patient to aneurysm development. Literature review reveals greater mortality for cervical lesions than thoracolumbar lesions and that the presence of meningitic symptoms portents better functional outcome than symptoms of cord compression. The outcome obtained in this case is consistent with outcomes reported in the literature.

    2015-01-01

    Background: A small aneurysm at an unusual location, such as a distal anterior inferior cerebellar artery (AICA) aneurysm, may conceal as a computed tomography angiography (CTA) and digital subtraction angiography (DSA)-occult aneurysm. Case Description: We herein present the case of a patient suffering from a subarachnoid hemorrhage (SAH) with two aneurysms in which the AICA aneurysm was negative by CTA and DSA. CTA demonstrated a right anterior choroidal artery aneurysm, which was revealed to be an unruptured aneurysm after surgical exploration. A small distal AICA aneurysm was detected by 3D rotational angiography (3DRA). The patient fully recovered except for left-side hearing loss four months after the second operation. Conclusion: We recommend a meticulous diagnosis by 3DRA in patients with SAH in which the distribution is not coincident with a typical aneurysmal location. PMID:26110079

    Apical hypertrophic cardiomyopathy (HCM) is a relatively uncommon inherited disease. Spontaneous coronary artery dissection (SCAD) is also uncommonly observed, which often occurs in pregnant or post partum women but is rare in men. This report describes a 38 years old man with apical hypertrophic cardiomyopathy who developed SCAD leading to acute inferior myocardial infarction. After emergent appendectomy operation at another hospital, he was immediately transferred to the Cardiology Department of our hospital due to acute myocardial infarction. He emergently underwent coronary angiography which showed a long dissection involving the right coronary. He underwent an emergent CABG with cardiopulmonary bypass. Postoperative recovery was uneventful and he was discharged. According to our knowledge, no case of spontaneous coronary artery dissection associated with apical hypertrophic cardiomyopathy unrelated to postpartum period or oral contraceptive use has been reported so far.

    We reviewed 13 cases of patients with unruptured dissections of the vertebral artery who were treated at our hospital after presenting with headaches. We identified 13 patients who had headache alone at the time of onset and who were diagnosed as having vertebral artery dissection using three-dimensional CT, MRI, MR angiography (MRA), or angiography from November 2007 to October 2009. Primary radiographic investigations showed the 'pearl and string' sign in two cases, dilatation in eight, and the string sign alone in three cases. Following initial conservative treatment, 11 cases exhibited radiographic improvement, but two cases underwent surgical treatment because of progressive vertebral artery dissection. A definitive diagnosis was made using primary investigations in nine cases and dynamic changes on radiographic investigations in four cases. The headache was located posteriorly in all cases, but some patients had mild headaches. Clinicians need to be aware of the possibility of vertebral artery dissection even if the headache is mild at onset. Radiographic investigations are important for a definitive diagnosis and in deciding whether to intervene surgically. (author)

    Dysphagia and hoarseness caused by laryngopharyngeal paralysis associated with internal carotid artery (ICA) dissection is rare. We reported a case which recovered spontaneously. A 57-year old man visited our hospital complaining of dysphagia and hoarseness lasting for two weeks. Paralysis of right vocal fold and rotational movement of the posterior pharyngeal wall toward the left side during swallowing were observed. Magnetic resonance imaging was performed under diagnosis of isolated right vagus nerve paralysis, and dissection of the right ICA was revealed. He was treated conservatively, and both of laryngopharyngeal movement and the ICA dissection were improved completely. There is a possibility that laryngeal paralysis caused by ICA dissection has been misdiagnosed as an idiopathic paralysis. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    We describe the case of a male patient, aged 76 years, referred for cardiac investigation due to retrosternal chest pain and dyspnea. He had a history of acute myocardial infarction and angioplasties in the last 30 years, including a saphenous vein coronary artery bypass grafting (SVCABG). Echocardiogram showed hypoechoic oval formation near the right ventricle, suggesting a pericardial cyst. Computed angiotomography revealed a predominantly fusiform and thrombosed aneurysmal dilation of the SVCABG to the right coronary artery. SVCABG aneurysms are very rare and potentially fatal. They usually appear in the late postoperative period, and patients are often asymptomatic. On radiography, it is frequently presented as enlargement of the mediastinum, with echocardiography, computed tomography and magnetic resonance imaging being very useful for diagnosis. Coronary angiography is the gold standard to detect these cases. Our report illustrates a rare situation arising late from a relatively common surgery. Due to its severity, proper recognition in the routine assessment of patients with a similar history is essential.

    Full Text Available Spontaneous coronary artery dissection(SCAD is a very rare cause of acute coronary syndrome. SCAD can cause stable angina, unstable angina, acute myocardial infarction, cardiogenic shock and sudden cardiac death. Predisposing factors include atherosclerosis, the peripar-tum period, structural and inflammatory conditions affect-ing the arterial wall. The diagnosis is usually made by coronary angiography. The clinical presentation is similar to the atherosclerotic coronary artery disease. Prompt diagnosis and treatment of patients improves survival. Therapeutic options include medical therapy, percutane-ous coronary intervention and surgery. The four cases were presented an discussed with review of the pertinent literature.

    The most prevalent lesion of the vertebral artery is an atheromatous plaque located at its origin from the subclavian artery. A case of successful management of a symptomatic vertebral artery aneurysm due to Ehlers-Danlos syndrome is reported. The patient had asymptomatic posterior intracerebral artery dissection on the contralateral side. A common carotid artery to V-3 segment bypass using reversed saphenous vein graft was carried out. Avulsion of the V-2 segment occurred peroperatively and endovascular coil embolization of the vertebral artery aneurysm was performed. Endovascular equipment and training must be in the armamentarium of vascular surgeons as more complex cases are being treated, which demands new approaches for ultimate clinical success. This unique case outlines what might unexpectedly occur. Endovascular intervention as an adjuvant procedure provides a satisfactory outcome in what could have been a catastrophe.

    The aim of this study was to assess if the complex anatomy of aortic aneurysm and aortic dissection can be accurately reproduced from a contrast-enhanced computed tomography (CT) scan into a three-dimensional (3D) printed model. Contrast-enhanced cardiac CT scans from two patients were post-processed and produced as 3D printed thoracic aorta models of aortic aneurysm and aortic dissection. The transverse diameter was measured at five anatomical landmarks for both models, compared across three stages: the original contrast-enhanced CT images, the stereolithography (STL) format computerised model prepared for 3D printing and the contrast-enhanced CT of the 3D printed model. For the model with aortic dissection, measurements of the true and false lumen were taken and compared at two points on the descending aorta. Three-dimensional printed models were generated with strong and flexible plastic material with successful replication of anatomical details of aortic structures and pathologies. The mean difference in transverse vessel diameter between the contrast-enhanced CT images before and after 3D printing was 1.0 and 1.2 mm, for the first and second models respectively (standard deviation: 1.0 mm and 0.9 mm). Additionally, for the second model, the mean luminal diameter difference between the 3D printed model and CT images was 0.5 mm. Encouraging results were achieved with regards to reproducing 3D models depicting aortic aneurysm and aortic dissection. Variances in vessel diameter measurement outside a standard deviation of 1 mm tolerance indicate further work is required into the assessment and accuracy of 3D model reproduction. © 2017 The Authors.

    The purpose is to determine the clinical neuro-radiological features of dolichoectatic intracranial vertebrobasilar artery dissection. The clinical features native and post-contrast CT scans of five patients (4 men and 1 woman; age ranged from 25 to 68 years) with dolichoectatic intracranial vertebrobasilar artery dissection were analysed retrospectively for a period of 3 years. Diagnosis was confirmed by vertebral angiography. Clinical symptoms due to ischemic cerebellar and/or brain stem lesion were present in 4 patient, 2 of them had Wallenberg syndrome. Occipital and/or posterior neck pains were found in 4 patients. Subarachnoid hemorrhage was shown in 1 patient. The incidence of previously documented hypertension was 60% (3 of 5 patients). The prognosis was relatively good. Dolichoectasia was detected by native, post-contrast CT scans and reconstructions in all patients. Intimal flap was visualized with post contrast CT scans in 1 patients. Extension of the basilar artery tip into the third ventricle was detected in 3 patients. Ischemic low-density lesions were detected in 3 patients and subarachnoid hemorrhage in 1 patient. Vertebral angiography disclosed elongation and dilatation of the vertebral and basilar arteries, double lumen sign - the presence of a true and false lumen and an intimal flap, double density and retention of contrast medium. Ischemic symptoms and head and/or neck pain were the most common clinical findings. The double lumen sign considered as the only pathognomonic angiographic finding of arterial dissection, was found in all patients. Angiography is still considered the 'gold standard' for diagnosis of intracranial vertebrobasilar artery dissection. (author)

    Background Coronary artery aneurysm (CAA) is a rare finding, being mostly diagnosed on angiography or at autopsies. It is defined as being a dilation of the coronary artery that exceeds the diameter of the patient's largest coronary vessel by 1.5 to 2 times. Case Report We describe the operative correction of a giant right CAA measuring in excess of 10 cm. Conclusion Management of giant CAAs is not standardized and surgical strategy remains controversial. In our case, the patient has a successful surgical repair with no postoperative shunts on follow-up investigations.

    To investigate the feasibility,safety and follow-up results of multiple stents parallel placement and reconstruction technique for treating giant vertebrobasilar dissecting aneurysms. Five consecutive patients with giant fusiform vertebrobasilar dissecting aneurysms in Department of Neurology,Chinese People's Liberation Army General Hospital were retrospectively reviewed from April 2011 to October 2013. All patients were diagnosed vertebrobasilar dissecting aneurysms by MRI and digital subtraction angiography (DSA), the aneurysm size ranged 8.2-15.0 mm. All patients were treated by multiple stents parallel placement and reconstruction technique under general anesthesia. In the endovascular treatment process, 2-3 Solitaire or Neuroform self-expandable stents were parallel implanted in the maximum extension segment of the aneurysms to reconstruct the cavity of the aneurysm and solved the problem that the diameter of the intracranial stent is less than the diameter of the aneurysms. Multiple stents parallel placement can keep the stents stable in the cavity. The parallel stent can close the dissection as well as strengthen the aneurysm walls to alleviate the vessel pulsative compression of the brain stem. Furthermore, one of the parallel stents was selected for the main blood flow channel. Based on the main channel, telescope technique was used to completely covering the dissection. It can not only prevent the progress of dissection to normal regions, but also be helpful for blood flow channel reconstruction to reduce the hemodynamic disorders. All Patients received routine antiplatelet therapy before and after endovascular treatment. The operative procedures were succeeded in all patients. Five patients were implanted 18 stents (3 stents in 3 patients; 4 stents in 1 patient; 5 stents in 1 patient; parallel 3 stents in 2 patients; parallel 2 stents in 3 patients). The signs and symptoms of brain stem and posterior group of cranial nerves improved significantly. All

    Atherosclerosis might affect all arterial segments of the vascular system, thus peripheral arterial disease (PAD) accompanying coronary artery disease (CAD) is not uncommon. In addition to this coexistence, abdominal aortic aneurysm (AAA) is frequently associated with CAD. Although treatment strategies of CAD and PAD or CAD and AAA has been reported previously, treatment of these three pathologies has not been reported. The management of a therapeutic strategy is important for avoiding perioperative mortality and morbidity in CAD associated with AAA and PAD. We are reporting our simultaneous treatment strategy of three pathologies with endovascular AAA repair, stent implantation into the superficial femoral artery (SFA) and coronary artery bypass grafting (CABG).

    2010-01-01

    Full Text Available Background. Aneurysms of the extracranial vertebral artery are rare and can provide a diagnostic and therapeutic challenge. Methods. We reviewed the clinical history of a patient presenting with cervical radiculopathy, who harboured an extracranial vertebral artery aneurysm eroding the cervical spine. Results. CT Angiography and MR Angiography set the diagnosis, by revealing a left C5-C6 vertebral artery aneurysm with cervical root impingement. Bony reconstruction depicted enlargement of the C6 transverse foramen and a marked enlargement of the C6-C7 intravertebral foramen. The lesion was treated by intravascular proximal vertebral artery occlusion. Conclusions. Extracranial vertebral artery aneurysms require a high index of clinical suspicion. This is the first report of a vertebral artery pseudoaneurysm presenting with bony erosion, which supports a less minacious portrayal of vertebral artery aneurysms.

    Aneurysms arising from the distal anterior inferior cerebellar artery (AICA) are very rare. When the parent artery is an AICA-posterior inferior cerebellar artery (PICA) variant, occlusion of the artery, even distal to the meatal loop, leads to a significant area of cerebellar infarction. We report two cases of ruptured partially thrombosed distal AICA aneurysms. In both cases, the parent artery was an AICA-PICA variant. The aneurysms were clipped in one case and trapped following occipital artery (OA)-AICA anastomosis in another case. It is important to keep the OA as a donor artery for revascularization in the treatment of the AICA-PICA variant aneurysms, especially when the absence of intra-aneurysmal thrombus is not comfirmed preoperatively.

    The rupture of an acute dissection of the ascending aorta into the space surrounding the pulmonary artery is an uncommon occurrence. No previous cases of transient pulmonary hypertension caused by a hematoma surrounding the pulmonary artery have been documented in the literature. Herein, we report a case of acute aortic dissection presenting as secondary pulmonary hypertension

    The subcallosal artery is a proximal branch of the anterior communicating artery and has been recognized as the vessel responsible for fornix infarction. Fornix infarction caused by vascular damage to the posterior circulation has not been reported previously. A 26-year-old woman suffered from fornix infarction due to artery-to-artery embolism after vertebral artery dissection. Cerebral infarctions were also found in the left thalamus, body of the left caudate nucleus, and the left occipital lobe other than the fornix. Occlusion of the subcallosal artery results in cerebral infarction of fornix, anterior cingulate cortex, and genu of the corpus callosum. However, in our case, lesions were restricted to the territory of posterior circulation. In addition to subcallosal artery, lateral posterior choroidal artery, a perforating branch of the posterior cerebral artery, has been described to send branches to the fornix, so we speculated that the left lateral posterior choroidal artery was actually responsible for fornix infarction.

    To perform high-resolution magnetic resonance imaging (HRMRI) and determine clinical features of patients with acute symptomatic middle cerebral artery (MCA) dissection. Thirteen patients with acute symptomatic MCA dissection underwent HRMRI within 3 days after initial clinical onset. They also underwent routine brain MR imaging. HRMRI examinations included time-of-flight MR angiography (MRA), T2-weighted, T1-weighted, proton-density-weighted, and three-dimensional magnetization-prepared rapid acquisition gradient-echo (MPRAGE) sequences. Conventional angiography and MRA were used as reference standard to establish the diagnosis of MCA dissection. The angiographic findings and HRMRI findings such as intimal flap, double lumen, and intramural hematoma were analyzed in this study. All patients presented cerebral ischemia (median National Institutes of Health Stroke Scale score = 4, range = 0-18). String sign was seen on MRA in seven patients. However, double lumen was seen in all patients on HRMRI by intimal flap. High signal lesion on MPRAGE sequences around the dissection lumen due to intramural hematoma was seen in three patients. HRMRI can be used to easily detect the wall structure of MCA such as the intimal flap and double lumen in patients with acute symptomatic MCA dissection. MPRAGE can detect hemorrhage in false lumen of MCA dissection.

  18. Recurrent Rare Genomic Copy Number Variants and Bicuspid Aortic Valve Are Enriched in Early Onset Thoracic Aortic Aneurysms and Dissections.

    Full Text Available Thoracic Aortic Aneurysms and Dissections (TAAD are a major cause of death in the United States. The spectrum of TAAD ranges from genetic disorders, such as Marfan syndrome, to sporadic isolated disease of unknown cause. We hypothesized that genomic copy number variants (CNVs contribute causally to early onset TAAD (ETAAD. We conducted a genome-wide SNP array analysis of ETAAD patients of European descent who were enrolled in the National Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC. Genotyping was performed on the Illumina Omni-Express platform, using PennCNV, Nexus and CNVPartition for CNV detection. ETAAD patients (n = 108, 100% European American, 28% female, average age 20 years, 55% with bicuspid aortic valves were compared to 7013 dbGAP controls without a history of vascular disease using downsampled Omni 2.5 data. For comparison, 805 sporadic TAAD patients with late onset aortic disease (STAAD cohort and 192 affected probands from families with at least two affected relatives (FTAAD cohort from our institution were screened for additional CNVs at these loci with SNP arrays. We identified 47 recurrent CNV regions in the ETAAD, FTAAD and STAAD groups that were absent or extremely rare in controls. Nine rare CNVs that were either very large (>1 Mb or shared by ETAAD and STAAD or FTAAD patients were also identified. Four rare CNVs involved genes that cause arterial aneurysms when mutated. The largest and most prevalent of the recurrent CNVs were at Xq28 (two duplications and two deletions and 17q25.1 (three duplications. The percentage of individuals harboring rare CNVs was significantly greater in the ETAAD cohort (32% than in the FTAAD (23% or STAAD (17% cohorts. We identified multiple loci affected by rare CNVs in one-third of ETAAD patients, confirming the genetic heterogeneity of TAAD. Alterations of candidate genes at these loci may contribute to the pathogenesis of TAAD.

    The etiology of true and false splenic artery aneurysm is different, but the differential X-ray contrast diagnosis could be difficult. Purpose - to detect endoscopic ultrasonography (EUS) diagnostic capability for false and true splenic artery aneurysm by considering two clinical cases: With suspected stomach and pancreatic lesions. Patient, female, 50-year-old with suspected stomach lesion, complicated by gastric bleeding. Endoscopy - acute gastric ulcer. X-ray - submucosal gastric tumor. The patient was sent to the EUS with fine-needle aspiration. Patient, male, 73-year-old with suspected pancreatic neoplasm. Ultrasound - pancreatic cysts. Computed tomography (CT) - neoplasm of the pancreas body. Celiacography - splenic artery aneurysm. The patient was sent to the EUS to clarify the diagnosis. First patient EUS - anechoic rounded lesion with thick wall close to the stomach. Stomach wall layers were not differentiated above the lesion. Doppler - turbulent blood flow. EUS excluded submucosal lesion and proved the presence of aneurysm. CT confirmed the aneurysm. Post-operative histology - splenic artery pseudoaneurysm, destruction of the stomach wall and pancreatic parenchyma. Second patient EUS - ovoid solid-cystic lesion with thin hyperechoic "capsule." Doppler in cystic part - arterial blood flow. EUS suspected saccular splenic artery aneurysm with the neck and the residual lumen. Post-operative histology - true splenic artery aneurysm with thrombotic masses near the wall, pancreatic parenchyma was intact. EUS can reliably differentiate splenic artery aneurysm from gastric submucosal lesion and differentiate true and false aneurysm with high probability.

    The original 'candy-plug' technique has been reported to be beneficial for the treatment of residual perfused false lumen in patients with aortic dissection. However, this technique is also associated with several problems, such as narrowing of the true lumen and damage to the flap or vessel wall. Therefore, we modified the procedure to overcome these problems. Here we report a case in which the patient was successfully treated using the modified procedure. A 59-year-old man presented with chronic type B aortic dissection with aneurysmal dilatation. The patient had undergone prosthetic graft replacement of the ascending aorta for acute type A aortic dissection 3 years previously and replacement of the descending aorta for residual type B aortic dissection with aneurysmal dilatation 1 year previously. After these procedures, the residual false lumen aneurysm of the distal descending aorta expanded to 57-mm in diameter. Endovascular stent grafting was successfully performed using the modified 'candy-plug' technique with relining of the true lumen and occlusion of the false lumen. The patient was discharged 10 days after the procedure. Follow-up imaging at 1 year showed a completely thrombosed false lumen aneurysm. The modified 'candy-plug' technique is useful for treatment of residual type B aortic dissection with aneurysmal dilatation.

    A 42-year-old woman presented with Hunt and Hess grade (HHG) III subarachnoid hemorrhage (SAH) caused by a ruptured left distal anterior inferior cerebellar artery (AICA) aneurysm. Computed tomography showed a thin SAH on the cerebellopontine angle cistern, and small vermian intracerebral hemorrhage and intraventricular hemorrhage in the fourth ventricle. Digital subtraction angiography revealed the aneurysm on the postmeatal segment of left distal AICA, a branching point of rostrolateral and caudomedial branch of the left distal AICA. Despite thin caliber, tortuous running course and far distal location, the AICA aneurysm was obliterated successfully with endovascular coils without compromising AICA flow. However, the patient developed left side sensorineural hearing loss postoperatively, in spite of definite patency of distal AICA on the final angiogram. She was discharged home without neurologic sequela except hearing loss and tinnitus. Endovascular treatment of distal AICA aneurysm, beyond the meatal loop, is feasible while preserving the AICA flow. However, because the cochlear hair cell is vulnerable to ischemia, unilateral hearing loss can occur, possibly caused by the temporary occlusion of AICA flow by microcatheter during endovascular treatment.

    Isolated brain infarction in the anterior cerebral artery (ACA) territory is rare, and its etiology has not yet been fully elucidated. Thus, we aimed to determine the etiologic and clinical characteristics of patients with isolated ACA territory infarction due to arterial dissection. Of 2315 patients with acute cerebral infarction admitted to our hospital between April 2007 and September 2013, 34 patients (1.5%; 28 men, 6 women; mean age, 65 ± 15 years) suffered isolated ACA territory infarction. We performed cranial magnetic resonance (MR) imaging and MR angiography for all the patients. Whenever possible, we also performed 3-dimensional computed tomography angiography, digital subtraction angiography, and MR cisternography to diagnose the stroke subtype. The stroke subtypes of the 34 patients with isolated ACA territory infarction were atherothrombotic infarction, cardioembolic infarction, arterial dissection, and unclassified in 11 patients (32%), 11 patients (32%), 11 patients (32%), and 1 patient (3%), respectively. The mean ages at onset were 48 ± 9 and 72 ± 11 years in the dissection and nondissection groups, respectively (P < .001). Headaches were present at onset in 4 patients (36%) and 1 patient (4%) with and without dissection, respectively (P = .026). Blood pressure at onset was significantly higher among patients with dissection (systolic, 179 ± 34 mm Hg; diastolic, 102 ± 17 mm Hg) than among patients without dissection (systolic, 155 ± 30 mm Hg; diastolic, 86 ± 21 mm Hg; P < .05), and d-dimer values were significantly lower among patients with dissection (P = .034). Favorable clinical outcome (modified Rankin Scale score, 0-2) at discharge was achieved in 9 patients (82%) and 10 patients (43%) with and without dissection, respectively (P = .035). Patients with isolated ACA territory infarction demonstrated a relatively high frequency of dissection (32%). Patients with dissection were younger, had a higher frequency of headaches, and

    A 37-year-old woman presented with photophobia without visual loss associated with chiasmal compression by an unruptured anterior communicating artery (AcomA) aneurysm. She had suffered progressive photophobia for one year. Neuroimaging indicated an AcomA aneurysm attached to the chiasm. Photophobia was resolved following clipping of the aneurysm. AcomA aneurysm should be considered in patients who experience photophobia without visual loss.

    Quantitative measurements of intracranial vessel walls are reliable in 3-T high-resolution magnetic resonance imaging (HR-MRI). However, few reports have assessed the arterial wall after endovascular treatment (EVT) by 3-T HR-MRI. This study aimed to quantitatively analyze vessel walls in vertebrobasilar artery dissecting aneurysms after EVT. From May 2012 to December 2015, a total of 21 patients with 21 intracranial vertebrobasilar dissecting aneurysms (VBDAs) were enrolled in this consecutive study. All the VBDAs were characterized by intramural hematomas (IMHs ≥5 mm) and treated with reconstructive EVT. Images of preoperative and follow-up 3-T HR-MRI were used to evaluate the arterial wall. The relative signal intensity (RSI) of IMHs was quantified on T1-weighted imaging (T1WI) and magnetization-prepared rapid acquisition gradient-echo (MPRAGE). Angiographic follow-up was performed for a mean of 9.19 ± 3.22 months. According to angiographic results at follow-up, 21 patients were divided into 2 groups (progressive group, n = 6; stable group, n = 15). In the progressive group, RSI of IMHs was significantly increased on MPRAGE of follow-up 3-T HR-MRI compared with that before treatment (P < 0.05), and the difference was not significant on T1WI. However, in the stable group, RSI of IMHs was significantly reduced after treatment (P < 0.05). Persistent high signal intensity of IMHs in VBDAs after reconstructive EVT may be associated with the progression of VBDAs. It may also indicate an unsteady state of the aneurysm, which suggests that reconstruction of the parent artery is not satisfactory. Copyright © 2017 Elsevier Inc. All rights reserved.

  5. Facial nerve palsy, Kawasaki disease, and coronary artery aneurysm.

    Kawasaki disease is rarely complicated by cranial nerve VII palsy. This report describes a 15-month-old female presenting with 3 days of fever, irritability, and rash who was subsequently diagnosed with Kawasaki disease and treated with intravenous immunoglobulin. She was found to have mild coronary artery ectasia and developed an acute, transient, left-sided facial palsy on the sixth day of illness. Repeat echocardiography demonstrated worsening aneurysm and intravenous methylprednisolone was added to her treatment regimen. At 1 and 3 months post-discharge, echocardiography demonstrated resolution of her coronary aneurysm. This case makes 41 total described in the literature. Patients tend to be under 12-months-old and there is a higher association with coronary artery aneurysm in such patients compared to those without facial palsy who never even received treatment. Kawasaki disease associated with facial palsy may indicate increased inflammatory burden and patients may require additional anti-inflammatory agents and more vigilant echocardiography.

    We present the rare case of a 66-year-old Caucasian male patient presenting with intermittent left-side abdominal pain. He underwent a kidneys, ureters, and bladder computed tomography scan on which an incidental 45-mm giant aneurysm of the left anterior descending coronary artery was discovered along with 55-mm right-sided and 62-mm left-sided common iliac artery aneurysms and a 100-mm benign renal oncocytoma. He underwent on-pump coronary artery bypass grafting of the left anterior descending, left circumflex and right coronary arteries using internal mammary artery and saphenous vein grafts. He subsequently underwent simultaneous open left nephrectomy and bilateral common iliac aneurysm repair using a bifurcated tube graft. He made a full recovery postoperatively. Giant coronary artery aneurysms are rare. In the pediatric population, they are predominantly secondary to Kawasaki disease. In adults, atheromatous disease is the leading cause. The coexistence of giant coronary artery aneurysms with extracoronary artery aneurysms is extremely unusual. We propose that the identification of giant coronary artery aneurysms necessitates further imaging investigations to identify the presence of extracoronary aneurysms. To our knowledge, this is the first description of such a case in the literature. Copyright © 2014 Elsevier Inc. All rights reserved.

    Coronary artery aneurysm (CAA) is an uncommon clinical finding, with an incidence varying from 1.5%-4.9% in adults, and is usually considered a variant of coronary artery disease (CAD). CAA identified in the context of acute coronary syndrome (ACS) represents a unique management challenge, particularly if the morphology of the CAA is suspected to have provoked the acute clinical syndrome. CAA is associated with thrombus formation due to abnormal laminar flow, as well as abnormal platelet and endothelial-derived pathophysiologic factors within the CAA. Once formed, mural thrombus may potentiate the deposition of additional thrombus within aneurysmal segments. Percutaneous revascularization of CAA has been associated with complications including distal embolization of thrombus, no-reflow phenomenon, stent malapposition, dissection, and rupture. Presently, there are no formal guidelines to direct the management of CAA in patients presenting with ACS; controversies exist whether conservative, surgical, or catheter-based management should be pursued. In this manuscript, we present an extensive review of the existing literature and associated clinical guidelines, and propose a management algorithm for patients with this complex clinical scenario. Armed with this perspective, therapeutic decisions may be tailored to synthesize patient factors and preferences, individualized clinical assessment, and existing American Heart Association/American College of Cardiology guidelines for management of ACS.

    The patient, a 69-year-old woman, had been diagnosed with a heart murmur. A chest X-ray at a local clinic had shown an abnormal shadow. Since CT revealed a 3-cm-diameter mass close to the pulmonary artery, we performed a coronary angiography and diagnosed her as having a coronary artery aneurysm associated with a coronary-pulmonary artery fistula. We incised the aneurysm under cardiac arrest, the wall of which had three openings that were suture closed from the inside and outside. The coronary-pulmonary artery fistula was suture closed. A postoperative angiography confirmed the disappearance of the coronary artery aneurysm and the abnormal blood vessels. The patient had an uneventful postoperative course and was discharged on postoperative day 15. We report a rare case of coronary-pulmonary artery fistula with a coronary artery aneurysm for which surgery was followed by an uneventful postoperative course.

    Full Text Available A 58 year old man was involved in a high impact road traffic incident and was admitted for observation. Asymptomatic for the first 24 hours, he collapsed with symptoms and signs consistent with a cerebrovascular accident. Computed tomography angiogram (CTA and Magnetic resonance angiogram (MRA demonstrated bilateral internal carotid artery dissections and a left middle cerebral artery infarct. It was not considered appropriate to attempt stenting or other revascularistation. The patient was treated with heparin prior to starting warfarin. He made a partial recovery and was discharged to a rehabilitation facility. This case is a reminder of carotid dissection as an uncommon but serious complication of high speed motor vehicle accident, which may be silent initially. Literature Review suggests risk stratification before relevant radiological screening at risk patients. Significant advances in CTA have made it the diagnostic tool of choice, but ultrasound is an important screening tool.

    Some celiac artery aneurysms are not suitable for endovascular therapy. We describe the case of a 63-year-old man with a celiac trunk aneurysm extending to the hepatosplenic bifurcation. The aneurysm was resected and oversewn at the origin from the abdominal aorta. A saphenous vein bypass from the supraceliac aorta to the celiac artery bifurcation was performed using a sutureless anastomotic device (PAS-Port system; Cardica, Redwood City, Calif) to create the proximal anastomosis, eliminating the need for aortic clamping. This system is thought to make direct proximal aortic anastomosis safe and easy in patients requiring surgical reconstruction of celiac artery aneurysms.

    Primary dissection of a peripheral artery without involvement of the aorta is a rare entity. Warfarin is currently used as the standard oral anticoagulant in a variety of clinical settings. We report here on a case of focal dissection of the common iliac artery and the superficial femoral artery following prophylactic treatment with warfarin for a prosthetic heart valve. The patient's laboratory results showed a high international normalized ratio and prolongation of the activated partial thromboplastin time. Angiography showed a dissection of the left common iliac artery and the right superficial femoral artery. His symptoms immediately disappeared after deploying stents to the arterial dissections

    We describe the case of a 75-year-old man with a mycotic right coronary artery aneurysm without evidence of prosthetic valve endocarditis. Eight years previously he had undergone coronary artery bypass surgery and aortic valve replacement. He presented with methicillin resistant staphylococcus aureus septicaemia after a prolonged hospital admission. Further investigation revealed a large mycotic right coronary artery aneurysm prompting urgent surgical repair. This case, of a mycotic coronary artery aneurysm in an atherosclerotic native coronary artery, is an extremely rare entity, which is further complicated by the presence of a prosthetic aortic valve.

  17. Rebleeding of a Splenic Artery Aneurysm after Coil Embolisation

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Background. Splenic artery aneurysm (SAA is an uncommon and difficult diagnosis. SAA is more common in females. Only 20% of SAA is symptomatic and may present as a rupture. A ruptured SAA is associated with a 25% mortality rate. Case Presentation. We present a case of a male patient with a bleeding SAA that rapidly increased in size. Distal coiling was technically impossible and despite proximal coil embolisation the SAA continued to bleed. A laparotomy including splenectomy and partial pancreatectomy was performed with an uneventful patient recovery. Discussion. Endovascular management is currently considered the optimal treatment of SAA. However, careful monitoring and follow-up is needed after embolisation as rapid recanalization of the SAA may possibly occur, especially when distal coiling of the aneurysm is unsuccessful. Conclusion. Endovascular treatment of an SAA is not necessarily effective. Surgeons must be prepared to perform open procedures to further reduce mortality rates.

  18. Constipation following bilateral of internal iliac artery aneurysms

    Full Text Available A 72-year-old man presented with constipation. He was hypertensive and suffered from chronic constipation. On arrival, the patient was fully conscious, and his vital signs were stable. He requested an enema because this treatment had proved effective in the past. On physical examination, a hard palpable mass was detected in the lower abdomen. Computed tomography was performed with contrast media. It revealed an abdominal aortic aneurysm (AAA and bilateral internal iliac artery aneurysms (IIAAs; the latter obstructing the sigmoid colon. We believe that this obstruction was the cause of constipation. The patient underwent Y-graft replacement for the treatment of the AAA and bilateral IIAAs. The surgery was successful, and constipation has not recurred since. As constipation is the most common digestive disorder in the general population, all physicians should be aware that chronic constipation can be caused by bilateral IIAAs.

    We report a case of a mycotic pulmonary aneurysm associated with Candida endocarditis in a 53-year-old male with lymphoma. The initial diagnosis was a pulmonary artery aneurysm attributable to vasculitis, such as that associated with Behcet's disease, but a mycotic pulmonary artery aneurysm was later considered as a differential diagnosis. Identification of valve vegetation on the chest CT was helpful in this regard. We review the literature on the disease etiology, radiological findings, and management options.

    Outcomes of stent-assisted coil embolization (SACE) have not been well established in the setting of vertebrobasilar dissecting aneurysms (VBDAs) due to the low percentage of cases that need treatment and the array of available therapeutic options. Herein, we presented clinical and radiographic results of SACE in patients with VBDAs. A total of 47 patients (M:F, 30:17; mean age ± SD, 53.7 ± 12.6 years), with a VBDA who underwent SACE between 2008 and 2014 at two institutions were evaluated retrospectively. Medical records and radiologic data were analyzed to assess the outcome of SACE procedures. Cox proportional hazards regression analysis was conducted to determine the factors that were associated with aneurysmal recanalization after SACE.Stent-assisted coil embolization technically succeeded in all patients. Three cerebellar infarctions occurred on postembolization day 1, week 2, and month 2, but no other procedure-related complications developed. Immediately following SACE, 25 aneurysms (53.2%) showed no contrast filling into the aneurysmal sac. During a mean follow-up of 20.2 months, 37 lesions (78.7%) appeared completely occluded, whereas 10 lesions showed recanalization, 5 of which required additional embolization. Overall recanalization rate was 12.64% per lesion-year, and mean postoperative time to recanalization was 18 months (range, 3–36 months). In multivariable analysis, major branch involvement (hazard ratio [HR]: 7.28; p = 0.013) and the presence of residual sac filling (HR: 8.49, p = 0.044) were identified as statistically significant independent predictors of recanalization. No bleeding was encountered in follow-up monitoring. Stent-assisted coil embolization appears feasible and safe for treatment of VBDAs. Long-term results were acceptable in a majority of patients studied, despite a relatively high rate of incomplete occlusion immediately after SACE. Major branch involvement and coiled aneurysms with residual sac filling may predispose to

    2015-01-01

    Full Text Available Profunda femoris artery aneurysm (PFAA is an extremely rare entity, with most cases being asymptomatic, which makes obtaining an early diagnosis difficult. We herein report a case series of PFAA, in which more than half of the PFAAs, which presented with no clinical symptoms, were discovered incidentally. All PFAAs were treated surgically with aneurysmectomy with or without vascular reconstruction. In cases involving a patent superficial femoral artery (SFA, graft replacement of the profunda femoris artery (PFA is not mandatory; however, preserving the blood flow of the PFA is necessary to maintain lower extremity perfusion in patients with occlusion of the SFA. Therefore, the treatment of PFAAs should include appropriate management of both the aneurysmectomy and graft replacement, if possible.

    Coronary artery aneurysm is rare, and there is no established protocol for surgical indication. On preoperative examination of orthopedic surgery, a 76-year-old male was found with asymptomatic myocardial ischemia. Radiological examinations revealed triple vessel disease and a coronary artery aneurysm, 10 mm in size, at the bifurcation of the left main trunk. Combined with quintuple coronary artery bypass grafting, surgical repair of the aneurysm was peformed under cardiopulmonary bypass on beating heart. Epicardial echocardiography was used to detect the site and the blood flow on the aneurysm. Postoperative course was uneventful. Epicardial echocardiography was useful for detecting the coronary artery aneurysm in the myocardium and the residual aneurysmal blood flow.

    Post-ruptured intracranial aneurysm geometry models have been widely used in computational fluid dynamic studies to assess hemodynamic parameters associated with aneurysm rupture. However, their results may not be valid due to the morphological changes of the aneurysm after rupture. Our aim was to identify the hemodynamic features of aneurysms prior to rupture in comparison with unruptured aneurysms. We retrospectively identified three large unruptured internal carotid artery (ICA) aneurysms (pre-ruptured group) with adequate image quality just before rupture. Matched with the same location and similar size, eight unruptured aneurysms (unruptured group) were selected as controls during the same time period. Flow simulations for these aneurysms were performed to compare differences in hemodynamics. Compared with unruptured aneurysms, pre-ruptured aneurysms had a significantly more irregular aneurysm shape, a higher aspect ratio, and lower aneurysm averaged wall shear stress (WSS) (p=0.024, p=0.048, and p=0.048, respectively). Although pre-ruptured aneurysms had a lower low WSS area and higher Oscillatory Shear Index, these were not statistically significant. For large unruptured ICA aneurysms, low WSS, higher aspect ratio, and irregular shape were indicators of fatal rupture. Early treatment for such lesions with flow diverter and coils may be the best therapeutic option. Published by the BMJ Publishing Group Limited.

    We report the technique of three-dimensional computed tomography angiography (3D CTA)+two-dimensional computed tomographic (2D CT) imaging as an adjunct in early surgery for a ruptured anterior communicating artery (ACoA) aneurysm by adopting an anterior interhemispheric approach. These combined imaging modalities provide accurate intraoperative anatomical information. To produce images for an anterior interhemispheric approach, 3D CTA+2D coronal CT images, which are perpendicular to the direction of the surgical approach at three levels (brain surface, genu of the corpus callosum and aneurysm neck), were constructed. We also produced two 3D CTA+2D CT images of the lamina terminalis, with a horizontal 10-degree difference, to clarify the vascular architecture around the aneurysm stereotactically, as well as the dissection point and direction to open the lamina terminalis. Furthermore, we produced a 3D CTA+2D sagittal CT image at the midline, which allowed us to understand the anatomical architecture of the aneurysm, planum sphenoidale and tuberculum sellae. In addition, four different 3D CTA aneurysm images were produced for deciding the clip size preoperatively. The imaging findings in 28 patients with 28 ACoA aneurysms facilitated early clipping. Based on these 3D CTA+2D CT images, we conducted aneurysm surgery, and successfully performed neck clipping via an anterior interhemispheric approach. The combination of 3D CTA and 2D CT images is a feasible and useful method of image guidance for ACoA aneurysm microsurgery.

    Mediastinal aneurysms are rare but potentially life-threatening. Among these, bronchial artery aneurysms are most frequently reported, whereas up to now aneurysms of the proper esophageal artery had never been reported. A 69-year-old woman was referred to our hospital for treatment of a massive mediastinal hematoma. Enhanced computed tomography and selective proper esophageal arteriography revealed a 5-mm aneurysm in the proper esophageal artery that arises from the thoracic aorta at the Th8 level and has an anastomotic branch with the bronchial artery peripherally. Transcatheter arterial embolization was successfully performed using a mixture of N-butyl cyanoacrylate and lipiodol (1:3 ratio, 0.3 ml). Post-embolization angiography showed no filling into the aneurysm. The patient recovered with no complications and was discharged on the 25th post-procedure day.

    Full Text Available Background. Extracranial vertebral artery aneurysms are a rare cause of embolic stroke; surgical and endovascular therapy options are debated and long-term complication may occur. Case Report. A 53-year-old man affected by neurofibromatosis type 1 (NF1 came to our attention for recurrent vertebrobasilar embolic strokes, caused by a primary giant, partially thrombosed, fusiform aneurysm of the left extracranial vertebral artery. The aneurysm was treated by endovascular approach through deposition of Guglielmi Detachable Coils in the proximal segment of the left vertebral artery. Six years later the patient presented stroke recurrence. Cerebral angiography and Color Doppler Ultrasound well characterized the unique hemodynamic condition developed over the years responsible for the new embolic event: the aneurysm had been revascularized from its distal portion by reverse blood flow coming from the patent vertebrobasilar axis. A biphasic Doppler signal in the left vertebral artery revealed a peculiar behavior of the blood flow, alternately directed to the aneurysm and backwards to the basilar artery. Surgical ligation of the distal left vertebral artery and excision of the aneurysm were thus performed. Conclusion. This is the first described case of NF1-associated extracranial vertebral artery aneurysm presenting with recurrent embolic stroke. Complete exclusion of the aneurysm from the blood circulation is advisable to achieve full resolution of the embolic source.

    Ischemic complications after coil embolization of the PcomA aneurysms are not thoroughly understood, especially in cases in which the PcomA is sacrificed. Our purpose was to examine the preoperative angiographic features and pattern of postoperative cerebral infarctions exhibited by patients who underwent embolization of ruptured PcomA aneurysms with PcomA sacrifice. A retrospective review identified 14 patients with ruptured PcomA aneurysms who underwent embolization of the aneurysms in combination with PcomA sacrifice. Preoperative angiographic data, including the Allcock test, postoperative DWI, and neurologic status, were examined. Elimination of the aneurysm was complete in all cases. Postoperative DWI indicated 7 cases with infarctions (infarction group) and 7 cases without infarctions (noninfarction group). All patients in the infarction group developed infarctions in the vicinity of the tuberothalamic artery. In all 14 cases, a preoperative Allcock test demonstrated a retrograde filling of the PcomA through the P1 segment. The incidence of negative visualizations of the P1 segment on vertebral angiograms was significantly higher in the infarction group (100%) than in the noninfarction group (0%; P = .00058). The mean PcomA diameters, PcomA/P1 ratios, and aneurysm sizes observed in the infarction group were significantly greater than those in the noninfarction group (P sacrifice, tuberothalamic artery infarctions tended to occur in cases exhibiting negative visualization of the P1 segment, even when collateral flow was observed with the Allcock test.

    Coronary artery aneurysms (CAA) are the most serious late sequelae of Kawasaki disease, and periodic screening examinations are necessary. Two-dimensional (2D) echocardiography represents the standard screening method; however, visualization of the distal coronary arteries is often limited. This report documents the complimentary role of cine-CT with 2D echocardiography in the evaluation of CAA induced by Kawasaki disease. Six pediatric patients with coronary aneurysms were evaluated with both 2D echocardiography and cine-CT. Cine-CT detected ten of 11 lesions. The one misdiagnosed CAA was one of the two contiguous aneurysms. Owing to intersection thickness, these two discrete aneurysms were interpreted as a solitary aneurysm. Cine-CT detected one CAA not initially visualized on echocardiography. Cine-CT is effective and complementary to 2D echocardigraphy as a noninvasive method for the evaluation of coronary artery aneurysms occurring as sequelae of Kawasaki disease

    Allen L Ho

    Full Text Available Since the initial publication of the International Study of Unruptured Intracranial Aneurysms (ISUIA, management of unruptured intracranial aneurysms has been mainly based on the size of the aneurysm. The contribution of morphological characteristics to treatment decisions of unruptured aneurysms has not been well studied in a systematic and location specific manner. We present a large sample of basilar artery tip aneurysms (BTA that were assessed using a diverse array of morphological variables to determine the parameters associated with ruptured aneurysms. Demographic and clinical risk factors of aneurysm rupture were obtained from chart review. CT angiograms (CTA were evaluated with Slicer, an open source visualization and image analysis software, to generate 3-D models of the aneurysms and surrounding vascular architecture. Morphological parameters examined in each model included aneurysm volume, aspect ratio, size ratio, aneurysm angle, basilar vessel angle, basilar flow angle, and vessel to vessel angles. Univariate and multivariate analyses were performed to determine statistical significance. From 2008-2013, 54 patients with BTA aneurysms were evaluated in a single institution, and CTAs from 33 patients (15 ruptured, 18 unruptured were available and analyzed. Aneurysms that underwent reoperation, that were associated with arteriovenous malformations, or that lacked preoperative CTA were excluded. Multivariate logistic regression revealed that a larger angle between the posterior cerebral arteries (P1-P1 angle, p = 0.037 was most strongly associated with aneurysm rupture after adjusting for other morphological variables. In this location specific study of BTA aneurysms, the larger the angle formed between posterior cerebral arteries was found to be a new morphological parameter significantly associated with ruptured BTA aneurysms. This is a physically intuitive parameter that can be measured easily and readily applied in the clinical

    Dissection of the carotid and vertebral arteries is a not so uncommon cause of stroke and has to be considered as a differential diagnosis especially in younger patients. Therapeutic and prognostic implications are different from those in extracranial atherosclerotic disease. Dissection results from hemorrhage into the vessel wall usually between the layers of the media. Digital subtraction angiography (DSA) depicts the resulting luminal compromise that may reveal some typical, but not specific, findings. The same is true for non-invasive angiographic techniques such as time-of-flight magnetic resonance angiography (MRA) and computed tomography angiography (CTA), which have shown accurate results compared with DSA. The main advantage of these techniques is the direct visualization of the vessel wall confirming the intramural hematoma. This is achieved best with MR imaging due to the high signal of blood degradation products on T1- and T2-weighted images. Therefore, MRI in combination with MRA is presently the method of choice for initial diagnosis and follow-up of craniocervical artery dissection (CCAD). In some questionable cases, CTA is a non-invasive alternative that is independent of flow phenomena. (orig.)

    The purpose of our study was to compare selective arterially enhanced spiral computed tomographs (ACT) with digital subtraction angiographies (DSA) in the presurgical assessment of cerebral aneurysms. A total of 24 aneurysms in 18 patients were explored in a prospective study by ACT and DSA, using an interactive combined CT-angiography suite. Dimensions of the aneurysm, its relation to the parent vessel, and the aneurysmal index were defined on DSA and on surface-shaded display of 3D reformatted images obtained from ACT. Results were correlated with surgical findings. Three aneurysms suspected on DSA were not confirmed by ACT. One fusiform aneurysm suspected on DSA corresponded to a sacciform aneurysm on ACT. Surgical findings confirmed 20 sacciform aneurysms. The aneurysmal index could be measured in all 20 cases of sacciform aneurysms on ACT and could not be determined with confidence in 55 % of the cases on DSA. DSA and ACT gave identical results in 35 % of cases. In 10 %, the index measured by ACT was superior to that determined by DSA for aneurysms which had a diameter of less than 3 mm. In conclusion, the combination of DSA and ACT improved the results of DSA alone. ACT is a reliable method to measure the aneurysmal index in aneurysms with a diameter superior to 3 mm. (orig.)

    Neurofibromatosis type I (NF-1) is the most common neurocutaneous syndrome. Associated vascular abnormalities are arterial occlusion, aneurysm, ectasia and arteriovenous malformation. Spontaneous massive hemothorax due to rupture of an arterial aneurysm is rare but fatal. It is, therefore, essential to determine the location of an aneurysm and provide immediate surgical or the interventional treatment. We report a case of spotaneous hemothorax caused by rupture of an intercostal arterial aneurysm diagnosed by CT and angiography

    Although pulmonary artery aneurysms are a rare vascular anomaly, they are seen in a wide variety of conditions, such as congenital heart disease, infection, trauma, pulmonary hypertension, cystic medial necrosis and generalized vasculitis. To our knowledge, mycotic aneurysms caused by pulmonary actinomycosis have not been reported in the radiologic literature. Herein, a case of pulmonary actinomycosis complicated by mycotic aneurysm is presented. On CT scans, this case showed focal aneurysmal dilatation of a peripheral pulmonary artery within necrotizing pneumonia of the right lower lobe, which was successfully treated with transcatheter embolization using wire coils.

    Atherosclerotic aneurysms at the origin of an aberrant right subclavian artery (ARSA) are extremely rare entities of congenital origin. We report a case of a 62-year-old man who presented with dyspnea and upper chest pain. The CT scan and digital subtraction angiography revealed a 7-cm aneurysm of an ARSA arising from Kommerell's diverticulum. Deep hypothermic circulatory arrest was instituted and a transaortic approach was used for closure of the origin of the aneurysm with a prosthetic patch. A Dacron graft was interposed between the right subclavian artery and the ascending aorta and the aneurysmal sac was resected. The patient had an uneventful recovery.

  13. A Vertebral Artery Dissection with Basilar Artery Occlusion in a Child

    Full Text Available This paper presents the case report of an 11-year-old boy with an acute dissection with thrombosis of the left vertebral artery and thrombosis of the basilar artery. The patient was treated with acute systemic thrombolysis, followed by intra-arterial thrombolysis, without any clinical improvement, showing left hemiplegia, bilateral clonus, hyperreflexia, and impaired consciousness. MRI indicated persistent thrombosis of the arteria basilaris with edema and ischemia of the right brainstem. Heparinization for 72 hours, followed by a two-week LMWH treatment and subsequent oral warfarin therapy, resulted in a lasting improvement of the symptoms. Vertebral artery dissection after minor trauma is rare in children. While acute basilar artery occlusion as a complication is even more infrequent, it is potentially fatal, which means that prompt diagnosis and treatment are imperative. The lack of class I recommendation guidelines for children regarding treatment of vertebral artery dissection and basilar artery occlusion means that initial and follow-up management both require a multidisciplinary approach to coordinate emergency, critical care, interventional radiology, and child neurology services.

  14. Endovascular Treatment for a Ruptured Lumbar Artery Aneurysm in a Patient with von Recklinghausen Disease

    Full Text Available Introduction: Vasculopathy, such as an aneurysm, stenosis, rupture, or arteriovenous fistula, in patients with neurofibromatosis type I (NF-1; von Recklinghausen disease is well recognised. However, there has been no report regarding treatment for a ruptured lumbar artery aneurysm associated with NF-1. We present the first report of successful endovascular treatment by coil embolisation for a ruptured lumbar artery aneurysm in a patient with NF-I. Report: A 52 year old man with a history of NF-1 was referred with back pain and anaemia. The computed tomography scan showed rupture of a solitary lumbar artery aneurysm. The rupture was successfully treated by endovascular embolisation with a coil and N-butyl-2-cyanoacrylate. Discussion: Endovascular treatment with coil embolisation was performed safely in this patient. Keywords: Aneurysm, Arteries, Neurofibromatosis 1, Rupture, Case reports

  15. Computational predictions of damage propagation preceding dissection of ascending thoracic aortic aneurysms.

    Dissections of ascending thoracic aortic aneurysms (ATAAs) cause significant morbidity and mortality worldwide. They occur when a tear in the intima-media of the aorta permits the penetration of the blood and the subsequent delamination and separation of the wall in 2 layers, forming a false channel. To predict computationally the risk of tear formation, stress analyses should be performed layer-specifically and they should consider internal or residual stresses that exist in the tissue. In the present paper, we propose a novel layer-specific damage model based on the constrained mixture theory, which intrinsically takes into account these internal stresses and can predict appropriately the tear formation. The model is implemented in finite-element commercial software Abaqus coupled with user material subroutine. Its capability is tested by applying it to the simulation of different exemplary situations, going from in vitro bulge inflation experiments on aortic samples to in vivo overpressurizing of patient-specific ATAAs. The simulations reveal that damage correctly starts from the intimal layer (luminal side) and propagates across the media as a tear but never hits the adventitia. This scenario is typically the first stage of development of an acute dissection, which is predicted for pressures of about 2.5 times the diastolic pressure by the model after calibrating the parameters against experimental data performed on collected ATAA samples. Further validations on a larger cohort of patients should hopefully confirm the potential of the model in predicting patient-specific damage evolution and possible risk of dissection during aneurysm growth for clinical applications.

    We describe the case of a male patient, aged 76 years, referred for cardiac investigation due to retrosternal chest pain and dyspnea. He had a history of acute myocardial infarction and angioplasties in the last 30 years, including a saphenous vein coronary artery bypass grafting (SVCABG). Echocardiogram showed hypoechoic oval formation near the right ventricle, suggesting a pericardial cyst. Computed angiotomography revealed a predominantly fusiform and thrombosed aneurysmal dilation of the SVCABG to the right coronary artery. SVCABG aneurysms are very rare and potentially fatal. They usually appear in the late postoperative period, and patients are often asymptomatic. On radiography, it is frequently presented as enlargement of the mediastinum, with echocardiography, computed tomography and magnetic resonance imaging being very useful for diagnosis. Coronary angiography is the gold standard to detect these cases. Our report illustrates a rare situation arising late from a relatively common surgery. Due to its severity, proper recognition in the routine assessment of patients with a similar history is essential. (author)

    The aim of this work is to develop a new hyperelastic and anisotropic material mimicking histological and mechanical features of healthy and aneurysmal arterial tissues. The material is constituted by rhombic periodic lattices of hyperelastic fibres embedded into a soft elastomer membrane. To fit bi-axial experimental data obtained from the literature, with normal or pathologic human abdominal aortic tissues, the microstructure of the periodic lattices (fibre length, angle between fibres) together with the mechanical behaviour of the fibres (fibre tension-elongation curve) were optimised by using theoretical results arising from a multi-scale homogenisation process. It is shown that (i) a material constituted by only one periodic lattice of fibres is clearly not sufficient to describe all the experimental data set, (ii) a quantitative agreement between measurements and theoretical predictions is obtained by using a material with two fibre lattices, (iii) the optimised microstructures and mechanical properties of the fibrous lattices are strongly different for the abdominal healthy and aneurysmal arterial tissues, (iv) the anisotropic mechanical behaviour of the optimised material is described by only five parameters and (v) the optimal angles between fibres in the case of the healthy aorta are consistent with histological data. Several technical solutions of fibres can be considered as relevant candidates: this is illustrated in the particular cases of straight and wavy fibres. Copyright © 2012 Elsevier Ltd.

    Iliac artery aneurysms (IAA) and abdominal aortic aneurysms (AAA) frequently coexist. It remains unknown whether the content of trace elements in AAA walls depends on the coexistence of IAAs. The aim of this study was to compare the content of selected trace elements in AAA walls depending on the coexistence of IAAs. The content of trace elements was assessed in samples of AAA walls harvested intraoperatively in 19 consecutive patients. In the studied group, coexisting IAAs were diagnosed in 11 out of the 19 patients with AAA. The coexistence of IAAs was associated with a slightly lower content of nickel (0.28 (0.15-0.40) vs. 0.32 (0-0.85) mg/g; p = 0.09) and a significantly higher content of cadmium (0.71 (0.26-1.17) vs. 0.25 (0.20-0.31) mg/g; p = 0.04) in AAA walls. The levels of the remaining studied elements, copper, zinc, manganese, magnesium and calcium, were comparable. The elevated levels of cadmium in the walls of AAA coexisting with IAAs may suggest an impact of the accumulation of this trace element on the greater damage of the iliac artery wall.

    Full Text Available Dissections of the cervical arteries cause about 20% of total juvenile strokes. Approximately 4% of the carotid artery dissections are due to a (polytrauma such as car accidents. Despite improved diagnostic facilities, traumatic dissections are often underdiagnosed or diagnosed too late due to a lack of awareness of potential initial signs and symptoms.We report here a case of a delayed embolic stroke after a car accident caused by a dissection of the carotid artery and subsequent pseudoaneurysm.To reduce the long-term morbidity or mortality of multiple trauma patients, an early detection of cervical carotid and vertebral dissections is strictly necessary.

    Carotid artery dissection is a significant cause of stroke in young patients. It may be asymptomatic and go undiagnosed, or minimal transient manifestations may follow, commanding a higher index of suspicion than ordinarily exists to avoid misdiagnosis. Reported herein is a 27-year-old man who suffered extracranial internal carotid artery dissection while practicing a Brazilian Jiu-Jitsu submission maneuver. The patient's condition suddenly deteriorated one week later due to distal embolization and stroke. Despite endovascular treatment, with stenting of the cervical carotid artery, neurologic deficits remained. Of note, the objective in martial arts, which is to kill or incapacitate, has yet to be fully tempered in transitioning to sport. Brazilian Jiu-jitsu, a relatively new and fast-growing form of martial art, places emphasis on submission maneuvers. Related injuries are not common knowledge and are poorly described in the literature. This account is intended to shed light on the risk of this discipline. Through education and improved supervision, vascular injuries of this nature and the potentially lethal or disabling consequences may thus be prevented in young athletes.

    2017-01-01

    Alport syndrome (AS) is a genetic disorder due to inheritance of genetic mutations which lead to production of abnormal type IV collagen. AS has been associated with renal, auditory, and ocular diseases due to the presence of abnormal alpha chains of type IV collagen in the glomerulus, cochlea, cornea, lens, and retina. The resulting disorder includes hereditary nephritis, corneal opacities, anterior lenticonus, fleck retinopathy, temporal retinal thinning, and sensorineural deafness. Aortic and aortic valve pathologies have been described as extrarenal manifestations of AS in multiple case reports. One case report described intramural hematoma of the coronary artery. We report the first case of true spontaneous coronary artery dissection (SCAD) with an intimal flap as a very rare manifestation of AS. The patient is a 36-year-old female with history of AS with chronic kidney disease, hypertension, and obesity who presented to the emergency room with acute onset of substernal chest pain radiating to her neck and arms. Troponin was elevated, and ECG showed transient 1 mm ST-segment elevation in the inferior leads. Subsequent coronary angiography revealed localized dissection of the left circumflex artery. Percutaneous coronary angioplasty was performed and her symptoms improved. This case illustrates that SCAD may be a manifestation of AS patients with chest pain. PMID:28884028

    Kawasaki disease is a systemic vasculitis involving the coronary arteries at early childhood and cause coronary artery aneurysms and thrombotic occlusions. These coronary artery aneurysms were usually transformed later into stenotic or obstructive lesions, however, the majority of these aneurysms, even the giant ones, are known to be associated with normal epicardial coronary flow. Flow reserve is difficult to assess in aneurysmal arteries with echo or angiography. We performed this study to question if there are abnormalities in flow reserve in myocardial tissue with normal epicardial arterial flow on angiography in patients with Kawasaki disease, dipyridamole stress and rest Tc-99m-sestamibi SPECT were performed in 37 patients (28 boys, 9 girls, mean age 6.6 years). We compared SPECT findings with coronary angiography (CAG) findings in 21 patients who did both studies after finding abnormality on echocardiaography. On CAG, aneurysms were found in 26 arteries of 16 patients, i.e., 10 left main arteries, 6 left anterior descending arteries (LAD), 2 left circumflex arteries (LCX), and 8 right coronary arteries (RCA). Localized and segmental stenotic lesions were found in 11 arteries in 9 patients (LAD: 4, LCX: 1, RCA: 6). Eight of the 10 patients with aneurysms had no obvious stenosis. On stress-rest SPECT, 16(43%) out of 37 patients showed normal perfusion and the other 21(57%) showed reversible or persistent decrease. Among 11 stenotic artery territories, 3(27%) showed persistent and/or reversible perfusion defects. The other 8 were normal. Among 26 aneurysmal artery territories, 12 artery territories showe perfusion decrease. Three of the 5 patients with normal CAG showed persistent and/or transient perfusion defects. Among 14 artery territories with perfusion decrease in the 16 patients, 3(21%) could be localized to vascular territory having stenosis of supplying coronary arteries, 12(86%) were related to the coronary artery aneurysms. Two were not related to

    Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of acute coronary syndrome in young patients. No clear factors exist to predict the natural history of the disease and the prognosis of the condition. Furthermore, current management practice of SCAD is based mainly on retrospective data and case series and clear management guidelines are lacking. In this article, we present a series of cases of patients with SCAD and we will discuss the different clinical presentations, the diagnostic approaches and the options of management of this cohort of patients. Our aim is to outline the challenges of diagnosis and management of this interesting and serious pathology.

    The incidence of concomitant carotid artery stenosis and unruptured intracranial aneurysms (UIAs) has been reported at between 0.5% and 5%. In these patients, treatment strategies must balance the risk of ischemic stroke with the risk of aneurysmal rupture. Several studies have addressed the natural course of UIAs in the setting of carotid revascularization; however, the final recommendations are not uniform. The purpose of this study was to review our institutional experience with concomitant UIAs and carotid artery stenosis. We performed a retrospective review of all patients with carotid artery stenosis who underwent carotid artery endarterectomy (CEA) or carotid artery stenting (CAS) at our institution between 2003 and 2010. Only patients with preoperative imaging demonstrating intracranial circulation were included. Charts were reviewed for patients' demographic and clinical data, duration of follow-up, and aneurysm size and location. Patients were stratified into 2 groups: carotid artery stenosis with unruptured intracranial aneurysm (CS/UIA) and carotid artery stenosis without intracranial aneurysm (CS). Three hundred five patients met the inclusion criteria and had a total of 316 carotid procedures (CAS or CEA) performed. Eleven patients were found to have UIAs (3.61%) prior to carotid revascularization. Male and female prevalence was 2.59% and 5.26% (P = 0.22), respectively. Patients' demographics did not differ significantly between the 2 groups. The average aneurysm size was 3.25 ± 2.13 mm, and the most common location was the cavernous segment of the internal carotid artery. No patient in the study had aneurysm rupture, and the mean follow-up time was 26.5 months for the CS/UIA group. Concomitant carotid artery stenosis and UIAs is a rare entity. Carotid revascularization does not appear to increase the risk of rupture for small aneurysms (<10 mm) in the midterm. Although not statistically significant, there was a higher incidence of aneurysms found in

    Aneurysms of the anterior inferior cerebellar artery (AICA) are a rare entity. Purely intrameatal aneurysms are even rarer. The authors report an intrameatal thrombosed AICA aneurysm mimicking a vestibular schwannoma that was treated by resection and end-to-end anastomosis. This 22-year-old man presented with acute hearing loss, vertigo, and moderate facial palsy. Magnetic resonance imaging showed an atypical intrameatal lesion with dilation of the internal auditory canal. Microsurgical inspection via a retrosigmoid approach and drilling of the posterior wall of the internal auditory canal revealed a thrombosed AICA aneurysm. The aneurysm was excised, and an end-to-end suture was performed to restore AICA continuity. Intraoperative indocyanine green videoangiography as well as postoperative digital substraction angiography showed a good revascularization. Intrameatal AICA aneurysms may present with symptoms similar to vestibular schwannomas. End-to-end reanastomosis after aneurysm resection is a treatment option when clipping is impossible.

    Full Text Available When approaching the symptom of acute onset chest pain in a previously healthy 26-year-old male, anchoring heuristic presents a challenge to healthcare workers. This diagnostic error is the healthcare professional’s tendency to rely on a previous diagnosis, and, in situations where a set of symptoms might mask a rare and deadly condition, this error can prove fatal for the patient. One such condition, Spontaneous Coronary Artery Dissection (SCAD, is an uncommon and malefic presentation of coronary artery disease that can lead to myocardial infarction and sudden death. We present a case of SCAD in an otherwise healthy 26 year-old male who had been experiencing chest pain during and after sports activity. In the young, athletic male with SCAD, the danger of diagnostic error was a reality due to the broad symptomatology and the betraying demographics.

    2012-01-01

    Full Text Available A 65-year-old woman presented with a history of dyspnea and atypical chest pain. She was diagnosed with a non-ST-segment elevation myocardial infarction due to a giant right coronary artery aneurysm. After a failed percutaneous embolization, she was scheduled for right coronary artery aneurysm resection, posterior descending artery revascularization and mitral valve repair. During the induction of anesthesia and institution of mechanical ventilation, the patient suffered cardiovascular collapse. The transesophageal echocardiographic examination revealed tamponade physiology owing to compression of the cardiac chambers by the unruptured aneurysm, which resolved with the sternotomy. The surgery was carried out uneventfully.

    Traumatic external iliac artery dissection after renal transplant is a rare complication, but it should be urgently managed due to its devastating effects on graft and lower limb circulation. External iliac artery dissection is seen more in recipients with diabetes mellitus and comorbid disease. Recipients with external iliac artery dissection should be treated immediately by percutaneus angioplasty or surgical reconstruction. In this study, we reported the management of 2 kidney transplant cases with external iliac artery dissection due to vascular clamping of the artery. External iliac artery dissection was diagnosed by ultrasonography in both cases. After failed percutaneous interventional angioplasty, we reconstructed the external iliac artery dissection surgically and replaced the external iliac artery with polytetra-fluoroethylene grafts in both patients. Both patients were discharged with normal functioning grafts showing 0.9 and 0.8 mg/dL serum creatinine levels at month 3 posttransplant. Close monitoring of recipients after transplant is mandatory for early diagnosis and early management of external iliac artery dissection to prevent graft loss and preserve lower limb circulation. Routine Doppler ultrasonography is an inexpensive and useful tool for early diagnosis in cases of sudden cessation or decrease in urine. In cases of failed percutaneous interventional angioplasty, reconstruction with synthetic vascular grafts can be safely applied in external iliac artery dissection.

    The physiological infrarenal aortic diameter varies between 12.4 mm in women an 27.6 mm in men. As defined, an aneurysmatic dilatation begins with 29 mm. According to that, 9% of all people above the age of 65 are affected by an abdominal aortic aneurysm (AAA). Compared with the female sex, the male sex predominates at a rate of about 5:1. The disease is predominant in men of the white race. In black men, black and white women the incidence of AAA is identical. 38 to 50 percent of the AAA patients (patients) suffer from hypertension, 33 to 60% from coronary, 28% from cerebrovascular and 25% from peripheral occlusive disease. The AAA expansion rate varies between 0.2 and 0.8 cm per year and is exponential from a diameter of 5 cm on. In autopsy studies, the rupture rates with AAA diameters of <5 cm, between 5.1 and 6.9 cm, and of >7 cm were below 5%, 39% and 65%, respecitvely. 70% of the AAA patients do not die of a rupture, but of a cardiac disease. Serum markers, such as metalloproteinases and procollagen peptides are significantly increased in AAA patients. Thoraco-abdominal aneurysms (TAA) make up only 2 to 5% of all degenerative aneurysms. 20 to 30% of the TAA patients are also affected by an AAA. 80% of the TAA are degenerative, 15 to 20% are a consequence of the chronic dissection - including 5% of Marfan patients -, 2% occur in case of infections and 1 to 2% in case of aortitis. The TAA incidence in 100,000 person-years is 5.9% during a monitoring period of 30 years. In case of TAA, an operation is indicated with a maximum diameter of 5.5 to 6 cm and more and, in case of a Marfan's syndrome (incidence of 1:10,000), with a maximum diameter of 5.5 cm and more. With regard to aorto-iliac occlusive diseases, there are defined 3 types of distribution. Type I refers to the region of the bifurcation itself. Type II defines the diffuse aortoiliac spread of the disease. Type III designates multiple-level occlusions also beyond the inguinal ligament. Type I

    Background: Giant fusiform aneurysms of the distal middle cerebral artery (MCA) are rare lesions that, because of the absence of an aneurysm neck and the presence of calcified walls and partial thrombosis, can be difficult to clip without sacrificing the parent vessel. Moreover, when the aneurysm is located in the dominant hemisphere, it is not possible to test language and cognitive functions during surgical intervention, making the closure of the parent vessel extremely dangerous.

    Unruptured posterior communicating artery (PCOM) aneurysms can be difficult to diagnose and, when large (? 7mm), represent a substantial risk to the patient. While most unruptured PCOM aneurysms are asymptomatic, when symptoms do occur, clinical manifestations typically include severe headache (HA), visual acuity loss, and cranial nerve deficit. This case report describes an atypical initial presentation of a large unruptured PCOM aneurysm with symptoms mimicking trigeminal neuralgia, without...

    Aneurysms of the anterior inferior cerebellar artery (AICA) are relatively rare among intracranial aneurysms. They can occur in 1 of 3 regions of the AICA: 1) craniocaudal (high or low riding), 2) mediolateral-premeatal (proximal), and 3) meatal-postmeatal (distal). The management strategies for treatment differ according to the location and configuration of the aneurysm. The existing body of neurosurgical literature contains articles published on aneurysms arising from the AICA near the basilar artery (BA), intracanalicular/meatal aneurysms, and distal AICA. Several therapeutic options exist, encompassing microsurgical and endovascular techniques. The authors describe a case of treatment involving a large BA-AICA aneurysm approached via exposure of the presigmoid dura using a retromastoid suboccipital craniectomy and partial petrosectomy. Treatment of these lesions requires detailed knowledge of the anatomy, and an anatomical overview of the AICA with its arterial loops and significant branches is presented, including a discussion of the internal auditory (labyrinthine) artery, recurrent perforating arteries, subarcuate artery, and cerebellosubarcuate artery. The authors discuss the various surgical approaches (retromastoid, far lateral, subtemporal, and transclival) with appropriate illustrations, citing the advantages and disadvantages in accessing these AICA lesions in relation to these approaches. The complications of these different surgical techniques and possible clinical effects of parent artery occlusion during AICA surgery are highlighted.

    Full Text Available Background/Aim. Hypertension is a known predictor of proximal aortic dissection, but it is not commonly present in these patients on presentation. The associations between ascending aorta with left ventricular hypertrophy, cardiovascular risk factors and coronary atherosclerosis, and outcome of these patients are not fully elucidated. Methods. This retrospective study included 55 consecutive patients with acute type A aortic dissection treated surgically in our institution during the last 2 years. The diagnosis was based on imaging studies. Diameter of ascending aorta was measured with echocardiography. Results. The mean age of the patients was 55.4 ± 12.19 years, and 72.7% were men. A history of arterial hypertension was present in 76.4% of the patients. Maximal ascending aorta diameter was 4.09 ± 0.59 cm, while patients with frank aneurysm accounted for 5.5%. Systolic blood pressure on admission was < 150 mmHg in 58.2% of the patients. Diastolic blood pressure on admission was < 90 mmHg in 54.5% of the patients. Mean arterial pressure on admission was 104.9 ± 24.6 mmHg. No correlations were demonstrated between maximal ascending aorta diameter and diameter of the left ventricular wall, any obtained risk factor and with coronary artery atherosclerosis (p > 0.05. After six months 11 (20% patients died, while intrahospital mortality was 72%. According to logistic regression analysis which included traditional risk factors, echo parameters, coronary artery disease and logistic euro scor, mean arterial blood pressure was the independent predictor of a six-month mortality [RR 0.956; CI (0.918-0.994 ; p = 0.024]. Conclusion. In our population the acute type A aortic dissection occurred rarely in the setting of frank ascending aortic aneurysms > 5.0 cm. The majority of patients had a history of arterial hypertension. A history of arterial hypertension was not associated with maximal ascending aorta diameter. Mean arterial blood pressure was the

    The aim of this study is to characterize the different flows present at anterior communicating artery (AcoA) aneurysms and investigate possible associations with rupture. For that purpose, patient-specific computational models of 26 AcoA aneurysms were constructed from 3D rotational angiography images. Bilateral images were acquired in 15 patients who had both A1 segments of the anterior cerebral arteries and models were created by fusing the reconstructed left and right arterial trees. Computational fluid dynamics simulations were performed under pulsatile flow conditions. Visualizations of the flow velocity pattern were created to classify the aneurysms into the following flow types: A) inflow from both A1 segments, B) flow jet in the parent artery splits into three secondary jets, one enters the aneurysm and the other two are directed to the A2 segments, C) the parent artery jet splits into two secondary jets, one is directed to one of the A2 segments and the other enters the aneurysm before being directed to the other A2 segment, and D) the parent artery jet enters the aneurysm before being directed towards the A2 segments. The maximum wall shear stress in the aneurysm at the systolic peak (MWSS) was calculated. Most aneurysms in group A were unruptured and had the lowest MWSS. Group B had the same number of unruptured and ruptured aneurysms, and a low MWSS. Groups C and D had high rupture ratios, being the average MWSS significantly higher in group C. Finally, it was found that the MWSS was higher for ruptured aneurysms of all flow types.

    Full Text Available Our basic understanding of ascending thoracic aortic aneurysm (ATAA pathogenesis is still very limited, hampering early diagnosis, risk prediction, and development of treatment options. "Omics"-technologies, ideal to reveal tissue alterations from the normal physiological state due to disease have hardly been applied in the field. Using a metabolomic approach, with this study the authors seek to define tissue differences between controls and various forms of ATAAs.Using a targeted FIA-MS/MS metabolomics approach, we analysed and compared the metabolic profiles of ascending thoracic aortic wall tissue of age-matched controls (n = 8, bicuspid aortic valve-associated aneurysms (BAV-A; n = 9, tricuspid aortic valve-associated aneurysms (TAV-A; n = 14, and tricuspid aortic valve-associated aortic dissections (TAV-Diss; n = 6.With sphingomyelin (SM (OH C22:2, SM C18:1, SM C22:1, and SM C24:1 only 4 out of 92 detectable metabolites differed significantly between controls and BAV-A samples. Between controls and TAV-Diss samples only phosphatidylcholine (PC ae C32:1 differed. Importantly, our analyses revealed a general increase in the amount of total sphingomyelin levels in BAV-A and TAV-Diss samples compared to controls.Significantly increased levels of sphingomyelins in BAV-A and TAV-Diss samples compared to controls may argue for a repression of sphingomyelinase activity and the sphingomyelinase-ceramide pathway, which may result in an inhibition of tissue regeneration; a potential basis for disease initiation and progression.

    A traumatic internal carotid artery (ICA) aneurysm is rare and difficult to treat. Trapping of ICA is commonly performed owing to the difficulty of directly approaching ICA aneurysms. Recently, coiling the aneurysm itself was recommended if possible. However, it is controversial which of methods are best to completely treat aneurysm. We present the case of a 74-year-old man, who had experienced a head injury 8 years previously, with recurrent severe epistaxis. An ICA aneurysm was detected on ...

    Fusiform aneurysms on the basilar artery (BA) trunk are rare. The microsurgical management of these aneurysms is difficult because of their deep location, dense collection of vital cranial nerves, and perforating arteries to the brain stem. Endovascular treatment is relatively easier and safer compared with microsurgical treatment. Selective occlusion of the aneurysmal sac with preservation of the parent artery is the endovascular treatment of choice. But, some cases, particularly giant or fusiform aneurysms, are unsuitable for selective sac occlusion. Therefore, endovascular coiling of the aneurysm with parent vessel occlusion is an alternative treatment option. In this situation, it is important to determine whether a patient can tolerate parent vessel occlusion without developing neurological deficits. We report a rare case of fusiform aneurysms in the BA trunk. An 18-year-old female suffered a headache for 2 weeks. Computed tomography and magnetic resonance image revealed a fusiform aneurysm of the lower basilar artery trunk. Digital subtraction angiography revealed a 7.1×11.0 mm-sized fusiform aneurysm located between vertebrovasilar junction and the anterior inferior cerebellar arteries. We had good clinical result using endovascular coiling of unruptured fusiform aneurysm on the lower BA trunk with parent vessel occlusion after confirming the tolerance of the patient by balloon test occlusion with induced hypotension and accompanied by neurophysiologic monitoring, transcranial Doppler and single photon emission computed tomography. In this study, we discuss the importance of preoperative meticulous studies for avoidance of delayed neurological deficit in the patient with fusiform aneurysm on lower basilar trunk.

    Haemodynamics and morphology play an important role in the genesis, growth and rupture of cerebral aneurysms. The goal of this study was to generate and analyse statistical wall shear stress (WSS) distributions and shapes in middle cerebral artery (MCA) saccular aneurysms. Unsteady flow was simulated in seven ruptured and 15 unruptured MCA aneurysms. In order to compare these results, all geometries must be brought in a uniform coordinate system. For this, aneurysms with corresponding WSS data were transformed into a uniform spherical shape; then, all geometries were uniformly aligned in three-dimensional space. Subsequently, we compared statistical WSS maps and surfaces of ruptured and unruptured aneurysms. No significant (p > 0.05) differences exist between ruptured and unruptured aneurysms regarding radius and mean WSS. In unruptured aneurysms, statistical WSS map relates regions with high (greater than 3 Pa) WSS to the neck region. In ruptured aneurysms, additional areas with high WSS contiguous to regions of low (less than 1 Pa) WSS are found in the dome region. In ruptured aneurysms, we found significantly lower WSS. The averaged aneurysm surface of unruptured aneurysms is round shaped, whereas the averaged surface of ruptured cases is multi-lobular. Our results confirm the hypothesis of low WSS and irregular shape as the essential rupture risk parameters. PMID:21957117

    We present a 16-year-old boy with autoimmune liver disease and longstanding portal hypertension in whom a CT arteriogram demonstrated a large aneurysm arising from the distal, extra-parenchymal portion of the splenic artery. Because of its location adjacent to multiple venous collaterals, the aneurysm was indistinguishable from splenic varices on initial imaging with Doppler sonography and on portal venous-phase CT. There is an increased risk of rupture of splenic artery aneurysms in the post-liver transplant period, with high associated mortality, and therefore diagnosis of splenic artery aneurysm prior to liver transplantation is clinically important. It is quite possible that the diagnosis of splenic artery aneurysm in this case would have been missed in the absence of dedicated arterial-phase imaging. As radiologists strive to reduce radiation exposure in children, this case highlights a potential diagnostic pitfall of both Doppler sonography and venous or single-acquisition arterial/venous-phase CT angiogram in children with venous collaterals and an undiagnosed splenic artery aneurysm.

    2010-07-01

    Full Text Available “Haemosuccus pancreaticus” is an unusual cause of severe upper gastrointestinal bleeding and results from rupture of splenic artery aneurysm into the pancreatic duct. More commonly, it is a pseudoaneurysm of the splenic artery which develops as sequelae of pancreatitis. However, true aneurysm of the splenic artery without pancreatitis has rarely been incriminated as the etiologic factor of this condition. Owing to the paucity of cases and limited knowledge about the disease, diagnosis as well as treatment become challenging. Here we describe a 60-year-old male presenting with severe recurrent upper gastrointestinal bleeding and abdominal pain, which, after considerable delay, was diagnosed to be due to splenic artery aneurysm. Following an unsuccessful endovascular embolisation, the patient was cured by distal pancreatectomy and ligation of aneurysm.

    2013-01-01

    Anterior communicating artery aneurysm is the most common form of intracranial aneurysm and subarachnoid haemorrhage (SAH) is the common presenting feature of anterior communicating artery aneurysms. In general, patients with SAH from anterior communicating artery aneurysm present with neurological deficit. We report an interesting case of a 60-year-old man who presented with acute monocular vision loss accompanied by periorbital pain without any neurological deficit, finally diagnosed with SAH from ruptured anterior communicating artery aneurysm. Five months after immediate craniotomy with aneurysm neck clipping, his visual acuity was improved to 20/63 with a pale optic disc appearance. Acute retrobulbar optic neuropathy may be the sole manifestation of SAH from ruptured anterior communicating artery aneurysm. Unilateral decrease of visual acuity with periorbital pain, in the absence of other neurological change, may be the initial and isolated sign.

    Coexistence of aortic coarctation with aneurysm of subclavian artery is a uncommon situation and may require unusual treatment in patients. A 40-year-old patient diagnosed incidentally with left subclavian artery aneurysm coexisting with aortic coarctation. Patient was initially referred for hybrid treatment. Initially ostium of the left subclavian artery was covered with a stent-graft. Over a 30-month follow-up period aneurysm became thrombosed all the way up to the ostium of internal mammary artery. The patient did not present with neurological symptoms or signs of upper limb ischemia. Taking into consideration good blood supply to the axillary artery via reversed blood flow in the thyreocervical trunk, hence we decided not to proceed with cervicoaxillary bypass grafting. Implantation stent-graft into aorta coarctation with covering axillary artery is proper way of treatment and may need no other surgical procedures.

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare and often lethal cause of acute coronary syndrome, which typically affects young women and otherwise healthy individuals. SCAD can be diagnosed in patients undergoing coronary angiography and can be underestimated. Special techniques such as optical coherence tomography (OCT and intravascular ultrasound should be used when there is suspicion of the condition. In the majority of cases, the left anterior descending (LAD artery is involved; however, a few cases of the right coronary artery (RCA involvement have been reported. This article describes three cases of SCAD in women of different ages, all presenting with chest pain. Coronary angiography in conjunction with OCT was used for diagnosis in two of the cases. One of the patients had involvement of the proximal RCA and underwent percutaneous coronary intervention, whereas the other two patients had mid-LAD disease and were treated conservatively with medical therapy. Presently, there are no specific guidelines for the treatment of SCAD, and therapy is individualized according to extent and severity of the condition.

    Background Anterior inferior cerebellar artery (AICA) aneurysms are rare and published clinical experience with these aneurysms is limited. Objective The objective of this article is to report angiographic characteristics and results associated with premeatal, meatal and postmeatal segments, surgical and endovascular therapies. Methods A literature review was performed through PubMed using “anterior inferior cerebellar artery aneurysm” through January 2016. Clinical data, angiograms, management techniques, and patient outcomes were reviewed for 47 collected cases in 30 previous reports. Results Of these aneurysms, 21 (44.7%) were associated with meatal segment, 10 (21.3%) were postmeatal and 16 (34.0%) were premeatal. Patients with meatal aneurysms are more likely to present with subarachnoid hemorrhage and hearing loss and facial palsy (77.8%). Patient outcomes of meatal aneurysms presented with more neuropathies (51.7%) and cerebellar symptoms (14.3%) (p = 0.049). Four cases of meatal aneurysm with preoperative cranial nerve deficits (two VII and two VIII) showed improvement after surgery. Endovascular treatment achieved outcomes similar to surgical treatment (p = 0.327). Conclusions AICA aneurysms have a predilection for meatal segment. Patients with meatal aneurysms are more likely to present with subarachnoid hemorrhage and hearing loss and facial palsy. Patient outcomes of meatal aneurysms presented with more neuropathies and cerebellar symptoms. Endovascular treatment achieved outcomes similar to surgical treatment. PMID:27485045

Between January 1995 and January 2007, 2,112 aneurysms were treated in our institution, and 36 aneurysms in 35 patients were located on the SCA (incidence 1.7%). Two of three distal SCA aneurysms were excluded. All the remaining 34 SCA aneurysms, of which 22 (65%) were ruptured and 12 (35%) were unruptured, in 33 patients were treated by endovascular techniques. There were 6 men and 27 women ranging from 29-72 years. In 14 patients (42%) multiple aneurysms were present. Initial angiographic occlusion was (near) complete in 32 aneurysms (94%) and incomplete in 2 aneurysms (6%). Complications leading to permanent morbidity or death occurred in two patients (6.1%, 95% CI 0.6 to 20.60%). Outcome at 6 months follow-up in 31 surviving patients was GOS5 in 26 (84%), GOS4 in 4 (13%) and GOS3 in 1 patient (3%). There were no episodes of (re)bleeding during 118 patient-years of follow-up. The 6-month angiographic follow up in 28 SCA aneurysms and extended angiographic follow-up in 19 showed stable occlusion in 27 aneurysms. No additional treatments were performed. SCA aneurysms are rare with an incidence of 1.7% of treated aneurysms at our institution. They are frequently associated with other aneurysms. Endovascular treatment is effective and safe in excluding the aneurysms from the circulation. (orig.)

    We evaluated the usefulness of magnetic resonance angiography (MRA) for showing the topography of paraclinoid carotid artery aneurysms in 27 patients with 30 paraclinoid aneurysms undergoing conventional angiography, three-dimensional time-of-flight MRA and surgery. The anatomy shown on the axial MRA source images was consistent with that found at surgery. The neck of the aneurysm could always be identified on the source images, while it could not be analysed exactly on conventional angiography in 3 cases (10 %). The optic nerves, including those displaced by the aneurysm, were recognised in all patients. The anterior clinoid process was shown as a low-intensity rim or area contiguous with the cortical bone. The source images were of great value in understanding the topography of paraclinoid carotid artery aneurysms. (orig.). With 2 figs

    PulseRider (Pulsar Vascular, Los Gatos, California, USA) is a new endovascular device designed to treat wide-neck bifurcation intracranial aneurysms. Deployment of a stent through a PulseRider to treat an aneurysm's recurrence has never been described before. We report the case of a 55-year-old man who underwent coiling of an 8-mm anterior communicating artery aneurysm with assistance of a PulseRider neck reconstruction device. The 6-month digital subtraction angiography control showed aneurysm recurrence, so we deployed an Enterprise 2 closed-cell stent (Codman, Miami Lakes, Florida, USA) in the A1-A2 segment passing across the previously implanted PulseRider. Enterprise correctly expanded and allowed for adequate coiling of the aneurysm. An Enterprise stent can be safely opened through a PulseRider in order to treat aneurysm recurrence.

    It is well known that patients with abdominal aortic aneurysm (AAA) often have concomitant coronary artery disease (CAD). In cases of AAA with severe CAD requiring coronary artery bypass grafting (CABG), two therapeutic strategies regarding the timing of CABG can be considered: staged or simultaneous operations. However, the ideal treatment of patients with large AAA and critical CAD remains controversial. We experienced a case of successful endovascular aneurysm repair after off-pump CABG in a 70-year-old patient who had a huge AAA and critical CAD.

    Coronary artery aneurysms are uncommon but potentially hazardous entities found on a small percentage of coronary angiograms. The best management strategy remains to be determined; the coexistence of obstructive coronary artery disease is the main determinant of prognosis. We report the case of a middle-aged woman with mixed aneurysmal and obstructive coronary artery disease presenting as an acute myocardial infarction, probably due to atherosclerosis. The unusual severity and complexity of the angiographic presentation of this case, with involvement of all major coronary arteries, raises important issues in terms of the patient's treatment options.

    There is limited understanding of the role of cardiac computed tomography angiography (CCTA) for assessment of patients with spontaneous coronary artery dissection (SCAD). In this report we describe the diagnostic utility of CCTA in three young women presenting with signs and symptoms of myocardial ischemia who were eventually diagnosed with SCAD. None of the women had traditional atherosclerotic risk factors. SCAD was not initially identified on CCTA in any of the three women, but was visualized during retrospective analysis in two patients after invasive coronary angiography. In two patients follow-up CCTA imaging was used successfully for subsequent management. In patients presenting with signs or symptoms of acute coronary syndrome, SCAD may be missed or not detectable on CCTA. A negative CCTA should not exclude a diagnosis of SCAD, and invasive coronary angiography should be considered for further evaluation.

    AICA aneurysms are rare and a challenge to treat surgically. We present our experience of the angiographic results and the clinical outcomes for 9 AICA aneurysms treated by EVT. Between 1997 and 2009, EVT was attempted for 9 AICA aneurysms. Six patients presented with SAH, and 3 aneurysms were found incidentally. The location of the aneurysms was the proximal AICA in 7 and the distal AICA in 2. Five aneurysms originated from an AICA-PICA variant. Clinical outcomes and procedural complications were evaluated, and angiography was performed 6, 12, and 24 months after embolization to confirm recanalization of the coiled aneurysm. EVT was technically successful in 7 patients (78%). Surgical trapping was performed in 1 patient after failure of EVT, and another aneurysm occluded spontaneously, along with the parent artery during EVT. In 7 patients, the AICAs had good patency on postoperative angiography. Stent-assisted coiling was performed in 3 patients. Follow-up angiographies were performed in 7 patients and showed no evidence of recanalization or progressive occlusion with further thrombosis except in 1 patient. There was no evidence of aneurysm rupture during the follow-up period, and 8 patients were able to perform all usual activities (mRS score, 0-1). EVT may provide a feasible and safe option as an alternative, though a microsurgical option is initially considered for the management of AICA aneurysms. Further follow-up and more experience are also necessary.

    Full Text Available The conflicting findings of previous morphological and hemodynamic studies on intracranial aneurysm rupture may be caused by the relatively small sample sizes and the variation in location of the patient-specific aneurysm models. We aimed to determine the discriminators for aneurysm rupture status by focusing on only posterior communicating artery (PCoA aneurysms.In 129 PCoA aneurysms (85 ruptured, 44 unruptured, clinical, morphological and hemodynamic characteristics were compared between the ruptured and unruptured cases. Multivariate logistic regression analysis was performed to determine the discriminators for rupture status of PCoA aneurysms.While univariate analyses showed that the size of aneurysm dome, aspect ratio (AR, size ratio (SR, dome-to-neck ratio (DN, inflow angle (IA, normalized wall shear stress (NWSS and percentage of low wall shear stress area (LSA were significantly associated with PCoA aneurysm rupture status. With multivariate analyses, significance was only retained for higher IA (OR = 1.539, p < 0.001 and LSA (OR = 1.393, p = 0.041.Hemodynamics and morphology were related to rupture status of intracranial aneurysms. Higher IA and LSA were identified as discriminators for rupture status of PCoA aneurysms.

    Full Text Available Abstract Background We report an intraoperative retrograde dissection of the aorta and its subsequent evaluation by transesophageal echocardiography (TEE. Case presentation A 78 year old woman with an ascending aortic aneurysm without dissection and coronary artery disease was brought to the operating room for aneurysm repair and coronary artery bypass grafting. After initiation of cardiopulmonary bypass through a femoral artery cannula, aortic dissection was noted and subsequently imaged by TEE. Conclusion Retrograde aortic dissection through the femoral artery is life-threatening. Intraoperative TEE can be used to diagnose this uncommon event, and should be considered after initiation of bypass.

    To summarize the clinical experience of Bentall operation combined with total arch replacement and stented elephant trunk implantation for serious Debakey I aortic dissecting aneurysm. Twelve patients with serious Debakey I aortic dissecting aneurysm underwent surgical treatment from January 2005 to December 2007. There were 10 male and 2 female with the mean age of (40.1 +/- 9.5) years old. There were acute aortic dissection in 9 cases, chronic aortic dissection in 3 cases. The inner diameter of aorta was (5.3 +/- 1.8) cm. There were Marfan syndrome in 4 cases, aortic regurgitation in all cases, severely persistent chest pain in 9 cases, acute left heart failure in 8 cases, and cardiac tamponade in 4 cases. Bentall operations combined with total arch replacement and stented elephant trunk implantation were performed by using deep hypothermic circulatory arrest and antegrade selective cerebral perfusion in all cases. Urgent surgery underwent in 9 cases. The mean interval between the onset of aortic dissection and the accomplishment of surgery was (41.0 +/- 15.9) hours. Cardiopulmonary bypass time was (191 +/- 26) min, average cross clamp time was (134 +/- 31) min, and average deep hypothermic circulatory arrest time was (50.0 +/- 14.5) min. One patient died in hospital. The time stayed in ICU was 3 to 27 d. Mental disorder in 6 cases, hemi-paralysis in 1 case, amputation in 1 case, hemorrhage of anastomosis in 1 case, hemorrhage of alimentary tract in 1 case, and pleural effusion in 4 cases were recorded. Eleven cases were followed-up for 8 weeks to 36 months. There were no bending of the stents and no obstruction in the vascular prosthesis.No re-operation was needed. One case died 6 months postoperatively. Bentall operation combined with total arch replacement and stented elephant trunk implantation is safe and effective for serious Debakey I aortic dissecting aneurysm, while good organs protection and consummate cardiopulmonary bypass were taken.

    Purpose: Guidewires have been reported as a useful occlusion material for large aneurysms of different locations with good short-term results. In this study we retrospectively evaluate long-term results of emergency embolization technique with guidewires in symptomatic internal iliac artery aneurysm (IIAA) impending rupture. Patients and methods: In four patients presented with acute abdominal pain, multidetector computed tomography revealed unstable, 7-14 cm large, IIAAs. Two patients were treated with coil embolization of distal branches followed by occlusion of aneurysmal sac with guidewires. In two patients embolization of aneurysmal sac alone was performed. Results: In three patients complete or near complete occlusion of the aneurysmal sac was achieved and abdominal pain ceased within hours. Two patients treated with embolization of distal iliac artery branches and aneurysmal sac developed claudication that lasted up to 1 year. Their aneurysms remained thrombosed and they were without symptoms until they died 31 and 56 months later of causes unrelated to IIAA. Two patients treated with embolization of the aneurysm alone were free of ischemic symptoms. Because of incomplete embolization of the sac in one patient open surgery treatment in a non-emergency setting was performed. Complete filling of aneurysmal sac was achieved in other patient but 2 years later his aneurysm re-opened and required open surgery treatment. Conclusion: Embolization of aneurysmal sac of large IIAA with guidewires may be effective for immediate treatment of impending rupture. Long-term results were better when embolization of the aneurysmal sac was combined with embolization of distal IIA branches.

    We report here on a case of popliteal aneurysm and rupture that occurred over a 10-day period and this was all secondary to salmonella infection. Computed tomography (CT) angiography of the extremity that was performed before and after aneurysmal rupture showed the aneurysm's rapid evolution to rupture over a short period of time. We also review the pathogenesis, clinical presentation, diagnostic approach and management of salmonella aneurysms

    A technique for stent-assisted coil embolization of a bilobed wide-necked saccular aneurysm of the anterior inferior cerebellar artery (AICA) with the AICA arising from the dome of the aneurysm is described. A middle-aged patient was referred for treatment of a bilobed saccular aneurysm identified on a CT angiogram performed for a subarachnoid hemorrhage which occurred 20 days prior to presentation. A diagnostic angiogram showed a bilobed wide-necked saccular aneurysm at the AICA origin with the AICA arising from the dome of the aneurysm and also supplying the territory of the posterior inferior cerebellar artery. The therapeutic procedure involved trans-aneurysmal cannulation of the AICA with the microcatheter left in situ. Another microcatheter was maneuvered into the larger dome of the aneurysm. A stent was then deployed in the basilar artery, jailing the previous microcatheter in the aneurysm. Helical Guglielmi detachable coils were deployed in the aneurysm resulting in complete occlusion of the aneurysm with preservation of the AICA. It is important to preserve a normal branch arising from the dome of an aneurysm although it is technically demanding and a relative limitation. This case report describes a technique of coiling a bilobed aneurysm with a vital branch arising from the dome, with preservation of the branch and complete occlusion of the aneurysm using two microcatheters and a stent. This expands the repertoire of endovascular treatment of complex aneurysms.

    Anterior inferior cerebellar artery (AICA) aneurysms are rare lesions whose treatment can involve microsurgical and/or endovascular techniques. Such treatment can be challenging and may carry a significant risk of neurological morbidity. To demonstrate a case involving a complex AICA aneurysm that was treated with a unique microsurgical approach involving trapping the aneurysm and performing in Situ bypass from the posterior inferior cerebellar artery (PICA) to the distal AICA. The nuances of AICA aneurysms and revascularization strategies are discussed. The aneurysm and the distal segments of AICA and PICA were exposed with a retrosigmoid and far lateral approach. A side-to-side anastomosis was performed between the adjacent caudal loops of PICA and AICA. The AICA aneurysm was then treated by trapping the aneurysm-bearing segment of the parent vessel between 2 clips. A postoperative angiogram demonstrated a patent PICA-AICA bypass and complete occlusion of the AICA aneurysm. There were no complications, and the patient made an excellent recovery. The combination of parent vessel sacrifice and bypass remains an excellent option for certain difficult-to-treat aneurysms. This case involving PICA-AICA bypass to treat an AICA aneurysm serves as an example of the neurosurgeon's ability to develop unique solutions that take advantage of individual anatomy.

    A ruptured aneurysm at the bifurcation of the left middle cerebral artery with an infra- optic course of the bilateral anterior cerebral arteries was found in a 28-year-old woman. Both abnormal anterior cerebral arteries arose from the ipsilateral internal carotid arteries, at the level of the origin of ophthalmic arteries, passed underneath the ipsilateral optic nerves and turned upward at the ventral portion of the optic chiasm. In addition, an aortic coarctation was found with the use of thoracic aortography. An infra-optic course of the bilateral anterior cerebral arteries is an extremely rare anomaly. An infra-optic course of the bilateral anterior cerebral arteries is frequently associated with cerebral aneurysms and possibly with a coarctation aorta. The clinical features, radiological findings and possible genesis of this anomaly are presented.

    Spontaneous rupture of an ovarian artery aneurysm is an extremely rare and usually life-threatening event, most often associated with pregnancy. A 46-year-old woman presented to the emergency room with left lower abdominal pain and cold sweating. Contrast-enhanced dynamic computed tomography (CT) showed a left retroperitoneal hematoma with extravasation of contrast medium. Reconstructed images of a spiral CT disclosed a leaking left ovarian artery aneurysm. An exploratory laparotomy with ligation of the aneurysm and evacuation of the hematoma was performed. This is the third case of ruptured ovarian artery aneurysm not related to pregnancy and the first reported case related to blood pressure. A review of the literature and practical considerations on this rare condition are presented. Copyright 2009 S. Karger AG, Basel.

    BACKGOUND: Abdominal aortic aneurysm (AAA) surgery provides a unique opportunity to study the impact of arterial stiffness on central haemodynamics, reflected in augmentation index (AI). The aneurysmal aorta is significantly stiffer than undilated age-matched aorta. AIM: We investigated whether replacement of an aneurysmal aorta with a compliant graft would result in a decrease in AI, which would thus decrease myocardial workload parameters. METHODS: Patients undergoing elective open or endovascular AAA repair were assessed with applanation tonometry and laser fluximetry pre-operatively, immediately and long-term post-operatively. RESULTS: Replacement of a small segment of abnormal conduit vessel resulted in improvements in AI, demonstrating that arterial stiffness can be surgically manipulated. CONCLUSIONS: These results reflect a decreased myocardial workload post-aortic grafting. This decrease in AI is important from a risk factor management perspective, and arterial stiffness should become a further recognised and screened for risk factor in patients with known aneurysmal disease.

    Innominate artery (IA) aneurysms represent 3% of all arterial aneurysms. Due to the risk of thromboembolic complications and spontaneous rupture, surgical repair is usually recommended on an early elective basis. We present the case of 81-year-old Caucasian male presenting with atypical anterior chest pain secondary to a large innominate artery aneurysm who underwent successful open surgical repair at our institution. In our experience, open correction via median sternotomy with extension into the right neck provides excellent exposure and facilitates rapid reconstruction with good short and long-term outcomes. Minimally invasive and endovascular approaches provide emerging alternatives to open IA aneurysm repair, however further research is required to better define optimal patient selection criteria and determine the long-term outcomes of these novel therapies.

    We present a case of left anterior descending (LAD) coronary artery aneurysm at the site of previous stent placement 3 years previously. The patient presented with recent worsening of angina. Angiography and 64 slice CT angiography confirmed the presence of 6mm aneurysm of LAD at the site of previous stent involving the origin of diagonal, with thrombus proximal and distal to the stent. This patient was successfully managed by taking the posterior wall of the anterior descending artery while suturing the heel of the left internal mammary artery (LIMA)-LAD anastomosis. The idea was to create severe stenosis upstream to prevent distal embolisation from the site of aneurysm. The diagonal was grafted with a saphenous venous graft. Follow-up angiogram at 3 months demonstrated successful exclusion of the aneurysm and unobstructed flow through the grafts.

    Full Text Available Introduction: We can define extracranial carotid artery aneurysm (ECAA as bulb dilatation greater than 200% of the diameter of the internal carotid artery (ICA or in a case of common carotid artery (CCA greater than 150% of the diameter. Surgical intervention is required for the treatment of this disease.Case report: This study presents an open vascular surgical procedure to resolve ECAA. We report a case of 61 years old woman with an extracranial internal carotid artery berry aneurysm, presented with a headache and dizziness when turning the head aside. Classic open surgery was performed and the lumen of berry aneurysm was separated with three clips from the lumen of ICA.Conclusions: The open surgical approach is the method of choice for the treatment of extracranial internal carotid artery pathological conditions.

    Isolated dissection of superior mesenteric artery is a rare condition and is usually treated surgically. We treated a patient with severe abdominal pain who was angiographically confirmed to have superior mesenteric artery thrombosis associated with isolated spontaneous dissection. He was treated initially by thrombolysis and oral anticoagulation, but recurrent symptoms developed with radiologic evidence of disease progression. We performed superior mesenteric artery stenting and recovery was uneventful

    Background Aneurysms affecting the aorta are a common condition associated with high mortality as a result of aortic dissection or rupture. Investigations of the pathogenic mechanisms involved in syndromic types of thoracic aortic aneurysms, such as Marfan and Loeys-Dietz syndromes, have revealed an important contribution of disturbed transforming growth factor (TGF)-β signaling. Objectives This study sought to discover a novel gene causing syndromic aortic aneurysms in order to unravel the underlying pathogenesis. Methods We combined genome-wide linkage analysis, exome sequencing, and candidate gene Sanger sequencing in a total of 470 index cases with thoracic aortic aneurysms. Extensive cardiological examination, including physical examination, electrocardiography, and transthoracic echocardiography was performed. In adults, imaging of the entire aorta using computed tomography or magnetic resonance imaging was done. Results Here, we report on 43 patients from 11 families with syndromic presentations of aortic aneurysms caused by TGFB3 mutations. We demonstrate that TGFB3 mutations are associated with significant cardiovascular involvement, including thoracic/abdominal aortic aneurysm and dissection, and mitral valve disease. Other systemic features overlap clinically with Loeys-Dietz, Shprintzen-Goldberg, and Marfan syndromes, including cleft palate, bifid uvula, skeletal overgrowth, cervical spine instability and clubfoot deformity. In line with previous observations in aortic wall tissues of patients with mutations in effectors of TGF-β signaling (TGFBR1/2, SMAD3, and TGFB2), we confirm a paradoxical up-regulation of both canonical and noncanonical TGF-β signaling in association with up-regulation of the expression of TGF-β ligands. Conclusions Our findings emphasize the broad clinical variability associated with TGFB3 mutations and highlight the importance of early recognition of the disease because of high cardiovascular risk.

    A 76-year-old woman presented with sudden massive melena, and superior mesenteric arteriography showed an aneurysm in the middle colic artery (MCA). Because she had a history of right hemicolectomy and ligation of the inferior mesenteric artery (IMA) during open abdominal aortic aneurysm repair, embolization of the MCA aneurysm was considered to pose a risk comparable to that of colonic ischemia. A microballoon occlusion test during occlusion of the MCA confirmed retrograde visualization of the IMA branches through the collateral arteries by way of the left internal iliac artery, and embolization was successfully performed using microcoils. No colonic ischemia or aneurysm rupture occurred after embolization.

    The occurrence, growth, thrombosis, and rupture of intracranial saccular aneurysms can be directly related to the effect of hemodynamic forces. We developed the phantom flow models and compared with the computer simulation program to analyse the flow pattern and hemodynamics that might be responsible for the intracranial arterial aneurysms. We designed the arterial phantoms of three major sites of intracranial arterial aneurysm ; 1) basilar artery tip, 2) internal carotid artery bifurcation, 3) curved area of internal carotid artery. Flow patterns in the aneurysmal portion of phantoms were evaluated with color Doppler system on the connection with automatic closed type of circulation system. Then, we compared the results with computer simulation. The hemodynamic characteristics of the phantoms were identical with those obtained by computerisation's. Three distinct zones of flow were identified by color Doppler studies on the aneurysm of the curved area of an internal carotid artery : 1) an inflow zone entering the aneurysm at the distal aspect of its orifice, 2) an outflow zone exiting the aneurysm at the proximal aspect of its orifice, 3) a central slow vortex.However, the phantoms of basilar artery tip and artery bifurcation showed a direct inflow stream at the dome of an aneurysm. Flow dynamics in the various phantoms of the aneurysms can be successfully evaluated with color Doppler imaging, and were consistent with those predicted by computer simulations

    A 77-year-old woman presented with an extremely rare exclusively intra-meatal anterior inferior cerebellar artery (AICA) aneurysm manifesting as subarachnoid hemorrhage. The aneurysm was located at a non-branching site of its meatal loop, deeply inside the internal auditory canal. The ipsilateral posterior inferior cerebellar artery was hypoplastic and the affected AICA supplied a wide vascular territory in the right cerebellum. The patient underwent microsurgical trapping of the distal AICA aneurysm in the acute stage. Collateral back flow to the parent artery was poor, so right occipital artery (OA)-AICA anastomosis was performed prior to aneurysm trapping. The postoperative course was uneventful, and magnetic resonance imaging after surgery did not demonstrate any ischemic change. Postoperative angiography showed complete disappearance of the AICA aneurysm and the apparently patent OA-AICA bypass. She did not suffer neurological deficit except for right incomplete hearing disturbance, and postoperative single photon emission computed tomography demonstrated absence of hemodynamic compromise in the cerebellum. OA-AICA anastomosis with aneurysm trapping could be the optimal surgical management of the AICA aneurysm located exclusively inside the internal auditory canal, especially if the parent artery supplies a wide vascular territory.

    Intracranial internal carotid artery aneurysms are an extremely rare cause of spontaneous epistaxis, with a few documented cases. The management of such cases is challenging due to the relative anatomical inaccessibility of the bleeding point. The aim of the present study was to acquaint the readers with this rare type of aneurysm presenting with epistaxis and to report our experience of treating cases of severe epistaxis due to internal carotid artery (ICA) aneurysms. Data of 4 patients with İCA aneurysms presenting with epistaxis from June 2011 to July 2013 was retrospectively reviewed. The age of patients ranged from 16 to 62 years. Duration of epistaxis ranged from 3 months to 3 years. Two patients had severe epistaxis following transnasal biopsy. Two patients had a history of trauma. Two patients developed hemodynamically instability. All the patients were managed with trapping of the aneurysm. Complete exclusion of aneurysm from circulation was achieved in all the patients. ICA aneurysms can rarely present as life-endangering epistaxis. In patients presenting with a history of craniocerebral trauma, traumatic pseudoaneurysm must be considered as a differential diagnosis. Trapping of the aneurysm is a good option if there is good cross circulation.

    Full Text Available Abstract Background Thoracic aortic aneurysms and dissections (TAAD is a critical condition that often goes undiagnosed with fatal consequences. While majority of the cases are sporadic, more than 20% are inherited as a single gene disorder. The most common familial TAA is Marfan syndrome (MFS, which is primarily caused by mutations in fibrillin-1 (FBN1 gene. Patients with FBN1 mutations are at higher risk for dissection compared to other patients with similar size aneurysms. Methods Fifteen family members were genotyped using Affymetrix-10K genechips. A genome-wide association study was carried out using an autosomal dominant model of inheritance with incomplete penetrance. Mutation screening of all exons and exon-intron boundaries of FBN1 gene which reside near the peak Lod score was carried out by direct sequencing. Results The index case presented with agonizing substernal pain and was found to have TAAD by transthoracic echocardiogram. The family history was significant for 3 first degree relatives with TAA. Nine additional family members were diagnosed with TAA by echocardiography examinations. The affected individuals had no syndromic features. A genome-wide analysis of linkage mapped the disease gene to a single locus on chromosome 15q21 with a peak Lod score of 3.6 at fibrillin-1 (FBN1 gene locus (odds ratio > 4000:1 in favour of linkage, strongly suggesting that FBN1 is the causative gene. No mutation was identified within the exons and exon-intron boundaries of FBN1 gene that segregated with the disease. Haplotype analysis identified additional mutation carriers who had previously unknown status due to borderline dilation of the ascending aorta. Conclusions A familial non-syndromic TAAD is strongly associated with the FBN1 gene locus and has a malignant disease course often seen in MFS patients. This finding indicates the importance of obtaining detailed family history and echocardiographic screening of extended relatives of patients

    Mycotic aneurysms are uncommon, especially those located in visceral arteries. We present a case of a patient with two visceral mycotic aneurysms due to bacterial endocarditis, one located in right upper pole renal artery and the second in the splenic artery. Both aneurysms were treated as endovascular embolization using microcoils. In the aneurysm located at the renal artery, the technique of stent-assisted coils embolization was preferred to avoid coils migration due to its wide neck. The stent used was the Solitaire AB, which was designed for the treatment of intracranial aneurysms and was used recently in acute stroke as a mechanical thrombectomy device. Complete embolization of the aneurysm was achieved, preserving all the arterial branches without nephrogram defects in the final angiogram.

    Giant fusiform aneurysms of the distal middle cerebral artery (MCA) are rare lesions that, because of the absence of an aneurysm neck and the presence of calcified walls and partial thrombosis, can be difficult to clip without sacrificing the parent vessel. Moreover, when the aneurysm is located in the dominant hemisphere, it is not possible to test language and cognitive functions during surgical intervention, making the closure of the parent vessel extremely dangerous. A 46-year-old woman presented with a one-year history of frontal headache without neurological deficit. A magnetic resonance imaging and an angiography showed a giant fusiform aneurysm of the left M2 tract. Because of the location and the absence of a neck, the aneurysm was considered difficult to coil and not amenable to preoperative balloon occlusion; thus, the patient was a candidate for surgical treatment. After a preoperative psychological evaluation, patient underwent awake craniotomy with the asleep-awake-asleep technique. A standard left pterional approach was performed to expose the internal carotid artery, the MCA and the aneurysm originating from the frontal branch of the MCA. Neurological examination responses remained unchanged during temporary parent artery occlusion, and trapping was successfully performed. Awake craniotomy is a useful option in intracranial aneurysm surgery because it permits neurological testing before vessels are permanently clipped or sacrificed. With the asleep-awake-asleep technique, it is possible to perform a standard pterional craniotomy, which allows good exposure of the vascular structures without cerebral retraction.

    2012-09-01

    The distal anterior inferior cerebellar artery (AICA) aneurysms located inside the internal auditory canal are rare. The association of the distal AICA aneurysms and an arteriovenous malformation (AVM) on the same arterial trunk is exceptional. Eight reports of a total of ten cases have been published and all of the reported aneurysms were located in the meatal or postmeatal segment of the AICA. Herein, we report a case of ruptured aneurysm in the intrameatal portion of the AICA accompanying an AVM fed by the same artery. A 55-year-old man suffering from subarachnoid hemorrhage due to a ruptured intrameatal aneurysm with a small AVM underwent surgical trapping of the meatal loop, resulting in uneventful recovery. Follow-up angiography demonstrated neither aneurysm nor residual AVM nidus. We propose that trapping of the meatal loop could be a safe and feasible alternative to unroofing followed by neck clipping in selected patients with an intrameatal aneurysm of the AICA. We also review here the relevant literature.

    Aneurysms of the pancreaticoduodenal arteries (PDA) are rare, accounting for man was transferred to our hospital with a 1-day history of abdominal pain and syncope. On admission, an abdominal and pelvis computerized tomographic (CT) scan identified a large mesenteric hematoma, a 1.9 cm PDA aneurysm, and an occluded celiac axis. Mesenteric angiography revealed no active aneurysm leak and a stenotic superior mesenteric artery (SMA) origin. All hepatic blood flow originated from the stenotic SMA via markedly enlarged PDA collaterals. The patient was brought to the operating room, where absence of the celiac axis was confirmed. An aorto-to-proper hepatic and SMA bypass was performed using a bifurcated polyester graft. The next day, the patient was brought to the angiography suite, where the PDA aneurysm was coiled. Postprocedure CT scans confirmed thrombosis of the aneurysm. Ruptured mesenteric artery aneurysms are a challenging problem for the vascular surgeon. PDA aneurysms are rare and often occur in an unfavorable location. There appears to be an association with anatomic anomalies of the mesenteric circulation. Prompt invasive and noninvasive diagnostic studies aid in the definitive management of this often fatal problem. Combined endovascular and open techniques can be used for successful treatment.

    The association of cerebral dural arteriovenous fistula (DAVF) and ipsilateral flow related aneurysm has infrequently been reported. We describe a male patient who presented with an acute haemorrhagic stroke and was found to have a large right fronto-parietal intra-parenchymal haemorrhage from the ruptured Borden type II DAVF in addition to a large venous aneurysm and a flow related intraosseous aneurysm of the contralateral middle meningeal artery (MMA) all clearly delineated by CT and DSA. He underwent emergency stereotactic evacuation of the intraparenchymal haemorrhage and successful surgical treatment of all the vascular lesions at the same time with residual neurological deficit. To our knowledge, this is the first such reported case. We discuss the challenging surgical treatment, emphasising the role of CT/DSA in management, and provide a literature review.

    The radiologic diagnosis of vertebral artery dissection (VAD) depends on characteristic intraluminal findings on angiography and intramural hematoma or a double-lumen sign on high-resolution vessel wall imaging. We aimed to evaluate the accuracy of intramural hematoma sign on susceptibility-weighted imaging (SWI) in VAD. We retrospectively analyzed SWI, phase map images and brain computed tomography (CT) of the consecutive patients who suffered an ischemic stroke in the vertebral artery territory from August 2010 to July 2012. We divided the patients into 2 groups: the VAD group and the nondissection group. VAD was diagnosed by conventional catheter angiographic findings (aneurysmal dilatation, pearl-and-string or tapered steno-occlusion) and pathognomonic findings such as intramural hematoma or a double-lumen sign on the source images of TOF-MRA, high-resolution T1-weighted MRI or high-resolution T2-weighted MRI. Intramural hematoma sign was considered positive if the patient had an eccentric or concentric hypointense signal lesion in the vertebral artery on SWI, a corresponding hyperintense signal on phase map and no evidence of calcification on the brain CT, suggesting blood products other than calcification. Two experienced neuroradiologists blinded to clinical information and angiographic findings were asked to judge for the presence of intramural hematoma sign on SWI. The accuracy of intramural hematoma sign on SWI was evaluated. Phase value, demographic and clinical data were compared between the VAD and the nondissection groups. Thirty-nine patients were included: 10 in the VAD group and 29 in the non-dissection group. Among the VAD group cases, intramural hematoma sign on SWI was positive in 9 of the 10 VAD cases and in 1 out of the 29 cases in the nondissection group. The intramural hematoma sign on SWI was significantly associated with VAD (p hematomas (n = 9) were all positive and those of calcified lesions (n = 13) were all negative (0.45 radian vs. -0

    An asymptomatic 48-year-old man presented with multiple aneurysms in a primary racemose hemangioma of the right bronchial artery. Bronchial arteriography revealed a tortuous artery with four fusiform aneurysms of varying sizes and aneurysmal dilatation with marked thrombus formation in the long segment of the distal portion. Because the tip of catheter could not pass beyond the aneurysmal dilatation, we performed balloon-occluded embolization using a mixture of N-butyl-2-cyanoacrylate (NBCA) and iodized oil. For four other aneurysms, we performed embolization using a coil alone or with NBCA. After 6 months, right bronchial arteriography revealed no enhancement of the aneurysms. Despite the rarity of this procedure, embolization with NBCA is a good option for bronchial artery aneurysm embolization.

    Aneurysms of the anterior choroidal artery (AChoA) are rare and often difficult to treat. Variations may be present and must be identified prior to treatment. We report a unique case of a ruptured aneurysm located at the origin of a duplicate branch of the AChoA. A 56-year-old male was admitted to our university hospital for coma. A brain CT scan showed a subarachnoid hemorrhage, and CT angiography revealed a duplication of the right AChoA, with an aneurysm located at the branch's origin. We decided to embolize this aneurysm. Four weeks later, our patient was able to transfer to the rehabilitation unit. To the best of our knowledge, this is one of the first descriptions of an aneurysm located at the origin of a duplicate branch of the AChoA.

    Unfused basilar arteries, frequently but erroneously referred to as 'fenestrations', are not uncommonly associated with aneurysms. The difficulty in treating these aneurysms lie in the fact that they are often wide necked and frequently incorporate both channels of the unfused segment, with varying calibres of the channels, necessitating technically challenging treatment strategies. It is important to preserve both channels because of the potential presence of perforating arteries originating from these segments. There are numerous case reports of such aneurysms being treated by coils alone, coiling with balloon assistance and stent-assisted coiling in configurations such as 'X', 'double barrel' or waffle cone. We present an exemplary case, in which an aneurysm on a partial unfused basilar segment was treated with parallel flow diverters with an excellent result on follow-up imaging. © The Author(s) 2015.

    Patients with haematoma secondary to middle cerebral artery aneurysm often require urgent surgical treatment consisting of evacuation of the haematoma and aneurysmal clipping. . We present our experience over 5 years with 12 patients who underwent surgery before the first 8h of bleeding. Surgery included craniotomy, evacuation of the haematoma, and aneurysmal clipping. Preoperative angiography was performed in all cases. All patients had a score of 4 or 5 on the scale of the World Federation of Neurological Surgeons. Five of the patients were evolving well after 1 year. Clinical status upon admission, temporal lobe versus sylvian location of the haematoma, right-hemisphere involvement, and a midline deviation of less than 2 cm, were all most frequently associated with a good prognosis. In our experience, and in the literature available to us, early surgery in patients with haematoma secondary to middle cerebral artery aneurysm offers acceptable results in patients with World Federation of Neurological Surgeons scores of 4 or 5.

    Full Text Available Drug abuse represents a significant health issue. Evidence suggests that recreational drug use has a direct effect on the cerebral vasculature and is of greater concern in those with undiagnosed aneurysms or vascular malformations. The authors report a case of thunderclap headache with a negative head CT and equivocal lumbar puncture after a drug-fueled weekend. The patient underwent diagnostic cerebral angiogram which demonstrated multisegmental, distal areas of focal narrowing of the middle, anterior, posterior, and posterior inferior cerebral artery and an incidental aneurysm. It is often difficult to determine the exact origin of symptoms; thus we were left with a bit of a chicken or the egg debate, trying to decipher which part came first. Either the aneurysm ruptured with associated concomitant vasospasm or it is a case of Call-Fleming syndrome (reversible cerebral artery vasoconstriction with an incidental aneurysm. The authors proposed their management and rationale of this complex case.

    Several studies revealed the epidemiology of Kawasaki disease-related hospitalizations among children in the USA and other countries. However, disparities of developing coronary artery aneurysms by race/ethnicity, patient socioeconomic status, and geographic locations remain unknown in the USA. Hospital discharge record data of patients with Kawasaki disease aged 19 years or younger were obtained from the 2003, 2006, 2009, and 2012 Kid's Inpatient Database. The data were weighted to estimate the annual hospitalization rates with respect to age, gender, and race/ethnicity in the USA. Multivariable logistic regression was conducted to ascertain the factors associated with the development of coronary artery aneurysms. Total annual hospitalization rates of Kawasaki disease showed a decreasing trend, ranging from 6.54 per 100,000 children in 2003 to 6.11 per 100,000 children in 2012 (p Kawasaki disease ranged from 2.25 to 3.20%. Factor associated with the development of coronary artery aneurysms was hospitals in West (OR 2.15, 95% CI 1.42-3.26). Race/ethnicity, health insurance status, and household income were not associated with the development of coronary artery aneurysms. Total hospitalization rates of Kawasaki disease showed a decreasing trend. Children admitted to hospitals in West region were more likely to develop coronary artery aneurysms.

    Multiple intrahepatic arterial aneurysms and spontaneous aneurysmal rupture associated with polyarteritis nodosa leading to hemoperitoneum are extremely rare occurrences, but the conditions can be life-threatening if left untreated because of the risk of massive hemorrhage. We report a case of a high-risk surgical patient with polyarteritis nodosa complicated by spontaneous rupture of multiple intrahepatic arterial aneurysms. He was initially treated with emergency gelatin sponge particle embolization, followed by maintenance steroid treatment. Complete resolution of intrahepatic arterial aneurysms was observed at follow-up.

    Background: Aneurysms of the anterior inferior cerebellar artery (AICA), especially those located in the distal portion of the AICA, are rare. There are few reported cases treated with surgery or endovascular embolization. Case Description: We report two cases of fusiform distal AICA aneurysms presenting with subarachnoid hemorrhage. Parent artery occlusion with coils and n-butyl cyanoacrilate (n-BCA) resulted in complete aneurysm occlusion and prevented rebleeding. Both patients presented postprocedure neurological deficits, but have made a good recovery at 4 and 10 months, respectively. Conclusion: Occlusion of the parent artery for the treatment of ruptured fusiform distal AICA aneurysms is effective but has significant neurological risks. PMID:21748047

From 1987 to 1995, twenty-eight patients with IC aneurysms were treated by proximal artery occlusion with detachable balloons. Of these patients, 4 had aneurysms arising from the supraclinoid portion of the IC artery, 23 had aneuryms arising from cavernous portion of the IC artery, and one had aneurysm arising from cervical portion of the IC artery. Of the 28 patients, 7 patients without CT or MR examinations were excluded in this study. The mean follow-up period was 18.6 months. The causes of aneurysm formation were spontaneous in 17 cases and traumatic in 4 cases. Of 20 patients with aneurysms arising from supraclinoid and cavernous portion of the IC artery, 16 patients (80%) had cranial nerve symptoms by mass effect. Five patients had epistaxis (3 patient), carotid cavernous fistula (1 patient) or subarachnoid hemorrhage (1 patient) due to aneurysm rupture. Two patients, each with aneuryms arising from supraclinoid and cervical portion of carotid artery had 9th and 12th cranial nerve symptom. There were three instances of complication after permanent occlusion; two patients had subarachnoid and intracerebral hemorrhage by aneurysm rupture and expired. One patient had ischemia of posterior cerebral artery teritorry after one day. Delayed ischemic event did not occur during the follow-up period. All aneurysms of the carotid artery below the level of ophthalmic artery presented radiographic proof of complete thrombosis within two months. However, complete thrombosis of aneurysm was considerably delayed in two aneurysms arising from the supraclinoid portion of the carotid artery. In long-term follow-up study, completely thrombosed aneurysms decreased in size slowly. But incompletely thrombosed aneurysms did not decrease in size for a long time and began to contract after

    We describe a 22-year-old woman admitted to hospital in emergency with nuchal headache and vomiting. CT scan disclosed subarachnoid hemorrhage. Digital subtraction angiography with three-dimensional rotational acquisitions showed a ruptured aneurysm of a right persistent primitive hypoglossal artery as the cause of symptoms and hemorrhage. The patient was successfully treated with endovascular coiling of the aneurysm. This is the second literature report describing endovascular treatment in this unusual condition.

    We herein report the case of an ST-elevation myocardial infarction due to bioresorbable vascular scaffold (BRS) failure. Optical coherence tomography (OCT) revealed the exact mechanism of late BRS stent thrombosis due to an acquired coronary aneurysm related to BRS. A drug eluting OCT-guided stenting over a failed BRS in the context of an acute coronary syndrome, with the simultaneous presence of a BRS thrombosis and coronary artery aneurysm, proved to be effective.

    Objective: To preliminarily evaluate the feasibility, safety and efficacy of stent placement for the treatment of wide-necked aneurysms located at internal carotid artery bifurcation. Methods: Eleven patients with wide-necked aneurysms located at internal carotid artery bifurcation, who were encountered during the period from Jan. 2004 to Dec. 2010 in hospital, were collected. A total of 16 intracranial aneurysms were detected, of which 11 were wide-necked and were located at internal carotid artery bifurcation. The diameters of the aneurysms ranged from 2.5 mm to 18 mm. Individual stent type and stenting technique was employed for each patient. Follow-up at 1, 3, 6 and 12 months after the procedure was conducted. Results: A total of 11 different stents were successfully deployed in the eleven patients. The stents included balloon expandable stent (n=1) and self-expanding stent (n=10). According to Raymond grading for the immediate occlusion of the aneurysm, grade Ⅰ (complete obliteration) was obtained in 4, grade Ⅱ (residual neck) in 2 and grade Ⅲ (residual aneurysm) in 5 cases. No procedure-related complications occurred. At the time of discharge, the modified Rankin score was 0-1 in the eleven patients. During the follow-up period lasting for 1-108 months, all the patients were in stable condition and no newly-developed neurological dysfunction or bleeding observed. Follow-up examination with angiography (1-48 months) showed that the aneurysms were cured (no visualization) in 4 cases, improved in 2 cases and in stable condition in one case. Conclusion: For the treatment of wide-necked aneurysms located at internal carotid artery bifurcation, stent implantation is clinically feasible, safe and effective. Further studies are required to evaluate its long-term efficacy. (authors)

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome and little is known about characteristics, treatment, and follow-up of patients with SCAD. Computed tomography angiography (CTA) plays an important role in the diagnosis and management of SCAD. Herein, we describe a case of a patient with SCAD who underwent successful conservative management, and in whom CTA was able to detect rapid healing of the dissection, 4.5 hours post-dissection.

    Spontaneous coronary artery dissection (SCAD) is an infrequently recognized but potentially fatal cause of acute coronary syndrome (ACS) that disproportionately affects women. Little is currently known about how patients with SCAD initially present. We sought to describe patients who presented to the emergency department (ED) with symptoms of SCAD to improve providers' awareness and recognition of this condition. We performed a retrospective medical record review of all patients who presented to the ED of a single academic medical center from January 1, 2002 through October 31, 2015 and were subsequently diagnosed with SCAD by angiography. These patients were identified by International Classification of Diseases, Ninth Revision codes and a Boolean search of the diagnosis field of the medical record. Data regarding patients' presentations and course were abstracted by two independent reviewers. We identified 20 episodes of SCAD involving 19 patients, all of whom were female. The majority of patients had 0-1 conventional cardiovascular disease risk factors. Most patients had chest pain (85%), initial electrocardiograms without evidence of ischemia (85%), and elevated initial troponin (72%). The most common diagnosis in providers' differential was acute coronary syndrome (ACS). Patients with SCAD present with similar symptoms compared to patients with ACS caused by atherosclerotic disease, but have different risk profiles. Providers should consider SCAD in patients presenting with symptoms concerning for ACS, especially in younger female patients without traditional cardiovascular disease risk factors, as their risk may be significantly underestimated with commonly used ACS risk-stratifiers.

    Spontaneous healing of spontaneous coronary artery dissection (SCAD) and left ventricular ejection fraction (LVEF) recovery is frequently observed clinically. However, LVEF on presentation and follow-up imaging has not been described. We hypothesize that LV dysfunction improves at follow-up after initial SCAD presentation. We included patients with nonatherosclerotic SCAD prospectively followed at Vancouver General Hospital, who had baseline assessment of LVEF and wall-motion abnormality (WMA) during their index presentation. A subset of these patients had repeat assessment of their ventricular function at follow-up. We compared the baseline LVEF and WMA with follow-up assessments and correlated to long-term cardiovascular outcomes. We included 277 SCAD patients who had baseline ventricular assessment performed. The average age was 52.4 ± 9.4 years, and 90.3% were female. All presented with myocardial infarction (24.2% STEMI, 75.8% NSTEMI). At baseline, the mean LVEF was 55.6% ± 9.1% and 72/277 (26.0%) had LVEF 50 µg/L (OR: 1.02, P = 0.005), and SCAD involvement of the LAD (OR: 2.5, P = 0.002) were independent predictors of baseline LVEF SCAD cohort, the majority of patients presented with WMA and had relatively normal LVEF. Over half had subsequent normalization of WMA and LVEF on follow-up assessment. © 2017 Wiley Periodicals, Inc.

    Coronary fistula is a rare coronary abnormality through which blood drains into the cardiac chamber, great vessel or other vessels. In addition, giant aneurysm arising from coronary fistula is rare pathologic manifestation. Herein, we presented a rare case of multiple giant coronary artery aneurysms arising from coronary to pulmonary artery fistula in a 79-year-old woman presenting with sudden loss of consciousness. The aneurysms were detected using thoracic computed tomography angiography and consequently confirmed by invasive coronary angiography.

    Mycotic aneurysm of external carotid artery is extremely rare. We herein report a case of external carotid artery (ECA) aneurysm following severe traumatic brain injury. A 24-year-old man with severe traumatic brain injury (TBI) following a car accident was referred to Rajaee Trauma Center Emergency Room affiliated to Shiraz University of Medical Sciences in Shiraz, Iran. He underwent ventriculostomy on arrival for intracerebral pressure (ICP) monitoring and for a second time due to hydrocephalus following decompressive craniectomy. He developed fulminant meningitis and ventriculitis during his hospital course. A bulged pulsatile lesion under the frontotemporal scalp resulted into the suspicion to underlying vascular pathology. Six-vessel angiography of brain was done which revealed mycotic aneurysm of external carotid artery. The patient underwent a two-week course of a combination of intravenous antibiotics. Follow-up angiography was performed which confirmed successful treatment of mycotic aneurysm of ECA. Mycotic aneurysm of ECA is extremely rare. To our knowledge, this is the first report of mycotic aneurysm of ECA following severe TBI which was successfully treated with antimicrobial therapy.

    Therapy of abdominal aortic aneurysms (AAA) is currently based on a high level of evidence. This is not true in the same manner for iliac artery aneurysms (IAA) which are frequently associated with AAAs and occur only rarely as isolated lesions. The therapeutic principles apply in the same way to both aneurysm locations. New findings, improved perioperative care and the rapid development of minimally invasive techniques require a constant update which is the aim of this article concerning the therapy of AAAs and IAAs. A systematic literature review was performed in PubMed and Medline and priority was given to recent publications with a high level of evidence. Endovascular aneurysm repair (EVAR) and open aneurysm repair (OAR) result in a similar long-term survival. The perioperative survival advantage with EVAR persists only during medium-term postoperative courses. The reintervention rate after EVAR is substantially higher compared to OAR. For older patients and those who are considered unfit for OAR the expected benefits from EVAR has not been proven to date. Aneurysmal ruptures after EVAR demonstrate that a life-long surveillance of these patients is necessary. Therapy of AAAs and IAAs is increasingly being performed by EVAR. Even the majority of complex aneurysms are amenable to minimally invasive treatment. Nevertheless, indications for OAR continue to exist. Screening for AAAs results in a decrease of aneurysmal ruptures for which EVAR is also gaining importance.

    Spontaneous coronary artery dissection (SCAD) is a rare entity that can cause acute myocardial infarction and sudden cardiac death (SCD) which often goes unrecognized. We report a case of SCAD in a young postpartum female who presented with sudden cardiac arrest. The patient was managed medically and found to have fibromuscular dysplasia (FMD). After being stabilized in the critical care unit, coronary angiography was performed which showed dissection of the left main artery, intramural hematoma, and the culprit lesion. Further investigation showed dissection of the left vertebral artery which was all consistent with a diagnosis of FMD. The patient was followed as an outpatient and a repeated coronary angiography demonstrated healed dissection site. In conclusion, this case exemplifies that prompt diagnosis along with medical management without the need of coronary artery bypass graft, and percutaneous coronary intervention can improve survival in SCAD.

    Intracranial dissections commonly present as ischemic stroke and as hemorrhagic stroke. In general, while either ischemic stroke or hemorrhagic stroke may develop, the simultaneous onset of both may also occasionally occur. In this report, we present a case of simultaneous development of ischemic stroke and hemorrhagic stroke due to an intracranial artery dissection.

    To evaluate the results of interventional endovascular therapy of incidental and symptomatic visceral artery aneurysms in the elective and emergency situation. 43 aneurysms in 38 patients (19 female, 19 male, mean age: 57 ± 16 years [18-82]) were treated between 2011 and 2015. The characteristics of the aneurysms (true vs. false aneurysm, size, etiology, location, symptoms) were considered. Furthermore, we evaluated the intervention with respect to technical success, embolic/occlusive agents used, therapy-associated complications and post-interventional follow-up. 23 true aneurysms (maximum diameter: 22 ± 18 mm [11 - 67mm]) and 20 false aneurysms (maximum diameter: 9 ± 33 mm [3 - 150 mm]) were evaluated. The splenic (n = 14) and renal arteries (n = 18) were most frequently affected. The etiology was most commonly degenerative-atherosclerotic (47%) or iatrogenic post-operative (19%). 18/48 interventions were performed due to active bleeding. False aneurysms were associated significantly more often with active bleeding (63 vs. 25%, p = 0.012). 41/48 treatments were technically successful. Re-intervention was necessary 6 times. In 2 cases the endovascular approach did not succeed. There was a complication rate of 10%, whereby only 4 minor and 1 major complications occurred. No patient suffered from permanent sequelae. Aneurysms were primarily treated by using coils and if necessary additional embolic agents (liquid embolic agent or vascular plugs) (75%). In the follow-up period, reperfusion of treated aneurysms occurred at a rate of 7% (n = 3). Interventional endovascular therapy of visceral artery aneurysms is safe and effective in the elective treatment of incidental aneurysms as well as in significantly more frequent hemorrhaging false aneurysms in the emergency situation.

    2007-07-15

    Aim: To elucidate the mechanism of occurrence of splanchnic artery aneurysm associated with coeliac artery stenosis due to compression by the median arcuate ligament, and also to discuss the management for this relatively rare condition. Materials and methods: Five consecutive cases of splanchnic artery aneurysm associated with coeliac axis stenosis due to compression by the median arcuate ligament, including four cases of pancreaticoduodenal artery aneurysm and one case of epiploic artery aneurysm, were investigated. These cases were collected over a 5-year period in our local and affiliated hospitals. Among these five cases, three were discovered because of rupture of the aneurysm, and two were found incidentally in annual medical check-ups. Results: In all cases, conspicuously developed collateral arteries, which were of the dilated pancreaticoduodenal arcade and its branches, were conspicuously found on digital subtraction angiography of the superior mesenteric artery. The findings suggested that haemodynamic changes in the splanchnic arterial networks (an increase in blood flow mainly through the pancreaticoduodenal arcade), were the possible cause of the corresponding aneurysms. Conclusion: Compression by the median arcuate ligament might be a frequent cause of splanchnic aneurysm, which, on rupture of the aneurysm, could be life-threatening.

    The traditional treatment of splenic artery aneurysm (SAA) is generally surgery and/or transcatheter arterial embolization, but recently, the treatment of SAA using a stent graft has been reported. However, the acute angle of the celiac axis, as well as the tortuous path of the splenic artery makes the use of stent graft difficult for treatment of aneurysma. We report here a case of SAA treated with the technique of double overlapping metallic stents.

    A 73-year-old woman had undergone hemiarch replacement with primary entry resection for treating acute type A dissection 6 years ago. Postoperative computed tomography (CT) showed a patent false lumen (FL) in the aortic arch and a reentry tear in the right subclavian artery. The remaining aortic arch enlarged, which resulted in formation of a 55-mm-diameter aneurysm. We performed reentry occlusion using embolization with glue and coil. The patient’s clinical course after the procedure was uneventful, and subsequent CT showed that FL was thrombosed and had decreased in size. PMID:29147154

    Vertebral artery dissection is a important cause of stroke in young patients. It may be spontaneous or traumatic and can lead to various clinical symptoms. We describe a case of 38-year-old man, with no preceding trauma or apparent inciting event, presented with the acute onset of imbalance, dysarthria, left-sided paraesthesias, headache, dysphagia, and dysmetria. Workup revealed a right vertebral artery dissection, ischemic stroke in the vertebrobasilar system, bulbar syndrome, right hemiparesis and cerebellar disorders. (authors)

    Spontaneous coronary artery dissection (SCAD) is still today an underdiagnosed disease due to the absence of angiographic hallmarks in more than 70% of cases. In several cases, an intravascular imaging is a sole tool for recognizing a dissection. Particularly, optical coherence tomography analysis (OCT) could represent the gold standard technique of easy interpretation and prompt diagnosis. Here we present a rare case of multivessel spontaneous coronary artery disease (SCAD) with atypical collateral circulation.

Diffusion-weighted MRI showed infarction in the territory of the left anterior cerebral artery (ACA and in the left posterior cerebral artery (PCA. In his vascular imaging, occlusion of the left vertebral artery (VA starting from V2 segment was consistent with dissection and pseudoaneurysm in the right ACA. We presented this case because of the presence of spontaneous and simultaneous occurrence of both intracranial and extracranial arterial dissections in OI.

    A 45-year-old female with Marfan syndrome had a Bentall's procedure performed 19 years ago. She presented with a 4-year history of gradually worsening dyspnea and decreasing exercise tolerance. Investigations revealed severe mitral valve prolapse, a left main stem coronary artery (LMSCA) aneurysm, and a recurrent aneurysm of the ascending aorta. The mitral valve was replaced and the aortic aneurysmal sac and the LMSCA aneurysm were then repaired by a modified Bentall procedure. The patient made an uneventful recovery and was discharged home.

    Aneurysms of the extracranial carotid arteries (ECAA) are extremely rare. Schechter et al. documented 835 cases in the literature up to 1977. One hundred and sixteen cases of ECAA have been documented in the Chinese literature since 1981, suggesting a higher prevalence of carotid aneurysmal disease in China than in the West. Four percent of all peripheral artery aneurysms are reported to be ECAA. Those arising from the internal carotid artery (EICAA) are even more rare. Two recent reviews reported 24 and 25 cases of EICAA during 21 and 17 years, respectively, the majority of them is treated surgically. Our literature review revealed only a few true EICAA managed endovascularly, but none of them with a covered stent. We describe a rare such case of ruptured atherosclerotic EICAA which was treated percutaneously

    We report on a case of a wide-necked aneurysm of the pancreatico-duodenal artery with occlusion of the celiac trunk in an asymptomatic patient. The aneurysm was considered to be at high risk of rupture. Successful embolization after interdisciplinary consultation was followed with color-coded duplex ultrasound (CCDS) demonstrating significant flow reduction. Three weeks later CCDS and angiography demonstrated exclusion of the aneurysm and a patent arterial supply of the liver and spleen fed by superior mesenteric artery (SMA) collaterals. The patient has done well so far, without major adverse clinical events or evidence for tissue necrosis of the liver, pancreas or spleen. Discussion of the case and review of the literature indicate that transcatheter embolization is the therapy of choice even in complicated cases

    To evaluate the incidence, management, and outcome of visceral artery aneurysms (VAA) over one decade. 233 patients with 253 VAA were analyzed according to location, diameter, aneurysm type, aetiology, rupture, management, and outcome. VAA were localized at the splenic artery, coeliac trunk, renal artery, hepatic artery, superior mesenteric artery, and other locations. The aetiology was degenerative, iatrogenic after medical procedures, connective tissue disease, and others. The rate of rupture was much higher in pseudoaneurysms than true aneurysms (76.3 % vs.3.1 %). Fifty-nine VAA were treated by intervention (n = 45) or surgery (n = 14). Interventions included embolization with coils or glue, covered stents, or combinations of these. Thirty-five cases with ruptured VAA were treated on an emergency basis. There was no difference in size between ruptured and non-ruptured VAA. After interventional treatment, the 30-day mortality was 6.7 % in ruptured VAA compared to no mortality in non-ruptured cases. Follow-up included CT and/or MRI after a mean period of 18.0 ± 26.8 months. The current status of the patient was obtained by a structured telephone survey. Pseudoaneurysms of visceral arteries have a high risk for rupture. Aneurysm size seems to be no reliable predictor for rupture. Interventional treatment is safe and effective for management of VAA.

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare cause of acute myocardial infarction. The disease is usually seen in young-middle aged women and leads to sudden death in the majority of cases. In survived patients, diagnosis of SCAD has been made with coronary anjiography. Involvement of left main coronary artery (LMCA is very unusual. We describe on a case of SCAD involving the LMCA in a young woman presenting with an acute myocardial infarction and cardiogenic shock status. There were no risk factors for coronary artery disease and no evidence of atherosclerosis on angiography. Coronary angiography revealed dissection of the LMCA that extended into the anterior descending and circumflex coronary arteries. The dissection was successfully treated with primary coronary artery stenting. The patient was discharged without complication. There was no problem in the first evaluation at the end of the first of the month. J Clin Exp Invest 2011; 2 (3: 299-303.

    Noonan syndrome is a constellation of congenital malformations including heart defects, facial anomalies and short stature. The cardiovascular defects are variable and extensive, with the most common being pulmonary stenosis and hypertrophic cardiomyopathy. Coronary artery anomalies have only been reported in a few cases. We report a child with Noonan syndrome status post pulmonary stenosis and atrial septal defect repair, who developed bilateral coronary artery aneurysms. The aneurysms were diagnosed with both cardiac magnetic resonance imaging and coronary computed tomography angiography. There had been no evidence of them on a cardiac MR exam 5 years previously.

    Internal carotid artery bifurcation aneurysms (ICAbifAs) present unique challenges to endovascular and surgical operators, and little is known about their natural history. We reviewed our institution's experience with ICAbifAs studying outcomes of surgical and endovascular management and natural history. Consecutive patients with unruptured ICAbifAs evaluated and/or treated over an 8-year interval were studied. Baseline demographics, neurovascular risk factors, aneurysm location and size, clinical presentation, treatment recommendations, and outcomes were prospectively collected and retrospectively analyzed. Continuous variables were compared with Student's t test and categorical variables with Chi-square tests. Fifty-nine patients with 61 unruptured ICAbifAs were included. Seven aneurysms were treated surgically (11.5 %), 22 underwent endovascular treatment (36 %), and 32 were managed conservatively (52.5 %). In the surgical group, short- and long-term complete aneurysm occlusion rates were 100 % with no cases of perioperative or long-term permanent morbidity or treatment-related mortality. In the endovascular group, two patients (11.7 %) with giant aneurysms had perioperative thromboembolic events with transient morbidity. There was one case of aneurysm rupture at follow-up in a giant aneurysm treated with partial coil embolization. Complete/near-complete occlusion rates were 63 %. There was one case of aneurysm rupture after 114 aneurysm-years of follow-up in the conservative management group (0.89 %/year), but no ruptures were observed in small aneurysms selected for conservative management. Unruptured small ICAbifAs have a benign natural history. In patients selected for treatment, excellent results can be achieved in the vast majority of patients with judicious use of endovascular and surgical therapy.

    OBJECT Unruptured posterior communicating artery (PCoA) aneurysms with oculomotor nerve palsy (ONP) have a very high risk of rupture. This study investigated the hemodynamic and morphological characteristics of intracranial aneurysms with high rupture risk by analyzing PCoA aneurysms with ONP. METHODS Fourteen unruptured PCoA aneurysms with ONP, 33 ruptured PCoA aneurysms, and 21 asymptomatic unruptured PCoA aneurysms were included in this study. The clinical, morphological, and hemodynamic characteristics were compared among the different groups. RESULTS The clinical characteristics did not differ among the 3 groups (p > 0.05), whereas the morphological and hemodynamic analyses showed that size, aspect ratio, size ratio, undulation index, nonsphericity index, ellipticity index, normalized wall shear stress (WSS), and percentage of low WSS area differed significantly (p < 0.05) among the 3 groups. Furthermore, multiple comparisons revealed that these parameters differed significantly between the ONP group and the asymptomatic unruptured group and between the ruptured group and the asymptomatic unruptured group, except for size, which differed significantly only between the ONP group and the asymptomatic unruptured group (p = 0.0005). No morphological or hemodynamic parameters differed between the ONP group and the ruptured group. CONCLUSIONS Unruptured PCoA aneurysms with ONP demonstrated a distinctive morphological-hemodynamic pattern that was significantly different compared with asymptomatic unruptured PCoA aneurysms and was similar to ruptured PCoA aneurysms. The larger size, more irregular shape, and lower WSS might be related to the high rupture risk of PCoA aneurysms.

    We present the first case of a hybrid endovascular approach to a penetrating aortic ulcer on the left descending aorta with a right aortic arch and aberrant left innominate artery arising from an aneurysmal Kommerell's diverticulum. The patient also had bilateral common iliac artery aneurysms. The three-step procedure consisted of a carotid-carotid bypass, followed by endovascular exclusion of the ulcer and the aneurysmal Kommerell's diverticulum, and then completion by covering the iliac aneurysms. The patient had no complications at 18 months after surgery. In such rare configurations, endovascular repair is a safe therapeutic option. Copyright © 2014 Elsevier Inc. All rights reserved.

    Pulmonary arteries aneurysms are rare and the rarely described bilateral aneurysms. A 45-year-old patient carrier of mitral stenosis was admitted for dyspnoea class III of the NYHA, chest pain and a not infectious cough. The clinical examination found semiology of mitral stenosis, tricuspid incapacity and pulmonary arterial hypertension. The electrocardiogram showed atrial fibrillation and right ventricle hypertrophy. Chest X-ray found a cardiomegaly, an aspect of double outline of the inferior right bow, a prominent aspect of the left average bow reminding an aneurysm of the left pulmonary artery. The echocardiography Doppler found a pure tight mitral stenosis (mitral surface=0.6 cm(2)), a dilation of the trunk of the pulmonary artery (diameter=74 mm) and of its branches (diameter of the right pulmonary artery=28 mm, diameter of the left pulmonary artery=36 mm) seat of a spontaneous contrast. The left atrium and right cardiac cavities were also dilated. There was an important tricuspid incapacity with a major pulmonary hypertension (systolic pulmonary arterial=109 mmHg). The thoracic angioscan showed a pseudoaneurysm of the trunk of pulmonary artery and its branches to their distal parts. Under diuretic, anticoagulating and analgesic treatment the clinical signs improved however the spontaneous contrast persisted. The patient was rejected by the surgery for exceeded clinical board. She is at present followed in our service for 5 months. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    Spontaneous coronary artery dissection (SCAD) is underdiagnosed and an important cause of myocardial infarction (MI), especially in young women. Long-term cardiovascular outcomes, including recurrent SCAD, are inadequately reported. This study sought to describe the acute and long-term cardiovascular outcomes and assess the predictors of recurrent SCAD. Nonatherosclerotic SCAD patients were prospectively followed at Vancouver General Hospital systematically to ascertain baseline, predisposing and precipitating stressors, angiographic features, revascularization, use of medication, and in-hospital and long-term cardiovascular events. Clinical predictors for recurrent de novo SCAD were tested using univariate and multivariate Cox regression models. The authors prospectively followed 327 SCAD patients. Average age was 52.5 ± 9.6 years, and 90.5% were women (56.9% postmenopausal). All presented with MI; 25.7% had ST-segment elevation MI, 74.3% had non-ST-segment elevation MI, and 8.9% had ventricular tachycardia/ventricular fibrillation. Precipitating emotional stressors were reported in 48.3% and physical stressors in 28.1%. Fibromuscular dysplasia was present in 62.7%, connective tissue disorder in 4.9%, and systemic inflammatory disease in 11.9%. The majority (83.1%) were initially treated medically, with only 16.5% or 2.2% undergoing in-hospital percutaneous coronary intervention or coronary artery bypass graft surgery, respectively. The majority of SCAD patients were taking aspirin and beta-blocker therapy at discharge and at follow-up. Median hospital stay was 3.0 days, and the overall major adverse event rate was 7.3%. Median long-term follow-up was 3.1 years, and overall major adverse cardiac event rate was 19.9% (death rate: 1.2%; recurrent MI: 16.8%; stroke/transient ischemic attack: 1.2%; revascularization: 5.8%). Recurrent SCAD occurred in 10.4% of patients. In multivariate modeling, only hypertension increased (hazard ratio: 2.46; p = 0.011) and

    Surgical treatment of basilar artery aneurysms presents a major challenge since it is crucial to preserve the flow to the vital brainstem perforators branching of the basilar artery. In some cases, basilar aneurysms can be treated by clipping vessels in order to induce flow reduction and aneurysm thrombosis. Patient-specific CFD models can provide guidance to clinicians by simulating postoperative flows resulting from alternative surgeries. Several surgical options were evaluated for four basilar aneurysm patients. Patient-specific models were generated from preoperative MR angiography and MR velocimetry data and modified to simulate different procedures. The Navier-Stokes equations were solved with a finite-volume solver Fluent. Virtual contrast injections were simulated by solving the advection-diffusion equation in order to estimate the flow residence time and determine thrombus-prone regions. The results indicated on procedures that reduce intra-aneurysmal velocities and flow regions which are likely to become thrombosed. Thus CFD modeling can help improve the outcome of surgeries altering the flow in basilar aneurysms.

    Kawasaki disease (KD) is an acute, self-limited vasculitis of unknown etiology that primarily affects the coronary artery (CA) and presents during childhood. The characteristic coronary arterial lesion of KD is an aneurysm. Ischemic heart disease derived from a CA aneurysm is experienced approximately two decades after the onset of acute KD. In recent years, the primary issue of concern has been asymptomatic adults with a CA aneurysm caused by undiagnosed KD. We present a case of sudden death as a late KD sequel in a young adult. A postmortem CT scan revealed a coarse calcification of a left anterior descending CA aneurysm, which was confirmed at the time of autopsy. A postmortem CT scan is useful in cases of sudden death where the detection of a calcified CA aneurysm would suggest to the forensic pathologist that the deceased suffered from a late sequel of KD. The use of screening postmortem CT scans for young people may detect cases of unsuspected CA aneurysms, raising the possibility of untreated KD. Copyright © 2012 Elsevier Ireland Ltd.

    Full Text Available ABSTRACT Objective Correlate the middle cerebral artery bifurcation aneurysm morphology with the pre-operative and intra-operative risk of rupture. Methods Forty patients with 46 middle cerebral artery bifurcation aneurysms were treated microsurgically by the same surgeon. Aneurysms were classified according to shape and the Fisher test was applied to analyze the effect of morphology on the pre-operative and intra-operative rupture. Results Pre-operative and intra-operative ruptures were observed in 8/46 patients (17.4% and 14/46 patients (30.4% respectively. Thirty-two cases (69.6% had no symptoms postoperatively, modified Rankin score (MRS of 0; 6.5% had MRS of 1 (no significant disability; 13% had MRS of 2 (slight disability; 4.3% had moderately severe disability (MRS of 4; and there were 3 deaths (6.5% post-operatively. The morphology was not directly related to the rupture rate. Conclusion In general, ruptures are not affected by the morphology or the studied variables. Larger series are needed to validate these outcomes.

    Purpose: In a clinical study 35 patients with intracranial aneurysms were examined using CT-angiography, MR-angiography (MRA) and digital subtraction angiography (DSA). The aim of the study was to establish the ability of noninvasive techniques to detect intracranial aneurysms. Material and methods: The CT examinations were performed using a spiral CT scanner and the MR investigations with a 1.5 T whole body MR-system. We used for MR-angiography Time of Flight (TOF) and Phase Contrast (PC) techniques. For postprocessing reconstructions modalities Maximum Intensity Projection (MIP), Surface and Volume Rendering Technique (VRT) techniques were used. The results were evaluated by the intraoperative findings. Results: Aneurysms up to 5 mm could be detected best using CTA and DSA. Giant aneurysms could be evaluated best using CTA. Volume rendering technique was the most useful postprocessing procedure. MRA using Time of Flight was superior compared with MRA using PC technique. (orig./AJ) [de

    Full Text Available Abstract Background Spontaneous carotid artery dissections have been rarely reported in children. Diagnosis has traditionally been confirmed by catheter arteriography. More recently diagnosis has been made by magnetic resonance imaging and magnetic resonance angiography; however the sensitivity of these techniques has yet to be determined. The authors are unaware of reports of carotid dissection confirmed by dynamic computed tomography (computerized tomographic arteriography in the young. Case presentation We recently evaluated a fourteen year-old male following the development of transient neurologic symptoms. There was no antecedent illness or trauma. Dynamic computed tomography revealed an intracranial dissection involving the supraclinoid segment of the left internal carotid artery (confirmed by catheter arteriography. Studies for vasculitis, pro-thrombotic states, and defects of collagen were negative. Conclusion Spontaneous carotid artery dissection is a potential cause of transient neurological symptoms and ischemic stroke in the pediatric population. Dynamic computed tomography appears to be a reliable diagnostic tool which can lead to early diagnosis.

    Full Text Available Intra-arterial treatment of aneurysms by redirecting blood flow is a newer method. The redirection is based on a significantly more densely braided wire stent. The stent wall keeps the blood in the lumen of the stent and slows down the turbulent flow in the aneurysms. Stagnation of blood in the aneurysm sac leads to the formation of thrombus and subsequent exclusion of the aneurysm from the circulation. The aim of the study was to evaluate flow diverter device Pipeline for broad neck and giant aneurysm treatment.

    Kawasaki Disease (KD) can result in coronary aneurysms in up to 25% of patients if not treated early putting patients at risk of thrombus formation, myocardial infarction and sudden death. Clinical guidelines for administering anti-coagulation therapy currently rely on anatomy alone. Previous studies including patient specific modeling and computer simulations in KD patients have suggested that hemodynamic data can predict regions susceptible to thrombus formation. In particular, high Particle Residence Time gradient (PRTg) regions have shown to correlate with regions of thrombus formation. Transluminal Attenuation Gradient (TAG) is determined from the change in radiological attenuation per vessel length. TAG has been used for characterizing coronary artery stenoses, however this approach has not yet been used in aneurysmal vessels. The aim of this study is to analyze the correlation between TAG and PRTg in KD patients with aneurysms and evaluate the use of TAG as an index to quantify thrombotic risk. Patient specific anatomic models for fluids simulations were constructed from CT angiographic image data from 3 KD aneurysm patients and one normal control. TAG values for the aneurysm patients were markedly lower than for the non-aneurysmal patient (mean -18.38 vs. -2). In addition, TAG values were compared to PRTg obtained for each patient. Thrombotic risk stratification for KD aneurysms may be improved by incorporating TAG and should be evaluated in future prospective studies.

    To evaluate the safety, efficacy, and mid-term outcomes of endovascular tubular stent-graft placement for repair of isolated iliac artery aneurysms (IAAs). Between January 2002 and March 2010, 20 patients (7 women and 13 men; mean age 74 years) underwent endovascular repair of 22 isolated IAAs. Two patients underwent endovascular repair for bilateral aneurysms. Ten para-anastomotic aneurysms (45%) developed after open abdominal aortic aneurysm (AAA) repair with an aorto-iliac graft, and 12 were true aneurysms (55%). Eleven straight and 11 tapered stent-grafts were placed. Contrast-enhanced computed tomography (CT) was performed to detect complications and evaluate aneurysmal shrinkage at week 1, 3, 6, and 12 months and once every year thereafter. Non-contrast-enhanced CT was performed in seven patients with chronic kidney disease. All procedures were successful, without serious complications, during the mean (range) follow-up period of 746 days (47-2651). Type II endoleak not requiring treatment was noted in one patient. The mean (SD) diameters of the true and para-anastomotic aneurysms significantly (p IAAs is safe and efficacious. Tapered stent-grafts of various sizes are required for accurate placement.

    Full Text Available Pseudo-aneurysm of the femoral artery is the most common arterial complication in drug injecting abusers. Scholars in vascular surgery have published debating statements regarding techniques of successful surgical management during last two decades. We present the results of simple arterial ligation in a series of 32 patients presenting with infected femoral pseudo-aneurysm. Most of the patients were males (89%. Young persons in the age group of 15-44 years were mostly affected. Site of lesion included common femoral artery in 65% , superficial femoral artery 28% and at bifurcation 6.2%. celulitis in 14 (53%, abscess & "ncelulitis in 6 (19%, necrosing fasciitis in 2 (6.2% and vascular abscess in 7 (22% cases were the forms of associated local infection. There was no hemorrhage, vascular thrombosis, amputation, or mortality. Claudicating were the only complications identified in 2 patients with Tripe ligation. Ligation is the optimal management for infected pseudo-aneurysms because it is easy, cost-effective, and safe. Early reconstruction is not recommended, since there is an extended infection in the location of the pseudo-aneurysm.

    Cervical artery dissection is a common cause of stroke in young people. The temporal profile of stroke risk after cervical artery dissection presenting without ischemia remains uncertain. We performed a crossover cohort study using administrative claims data on all emergency department visits and acute care hospitalizations from 2005 to 2011 in CA, 2006 to 2013 in NY, and 2005 to 2013 in FL. Using previously validated International Classification of Diseases, Ninth Revision, Clinical Modification codes, we identified patients with a cervical artery dissection and no previous or concurrent stroke or transient ischemic attack diagnosis. We compared the risk of stroke in successive 2-week periods during the 12 weeks after dissection versus the corresponding 2-week period 1 year later. Absolute risk increases were calculated using McNemar test for matched data. In a sensitivity analysis, we limited our population to patients presenting with typical symptoms of cervical artery dissection. We identified 2791 patients with dissection without ischemia. The absolute increase in stroke risk was 1.25% (95% confidence interval, 0.84-1.67%) in the first 2 weeks after dissection compared with the same time period 1 year later. The absolute risk increase was 0.18% (95% confidence interval, 0.02-0.34%) during weeks 3 to 4 and was no longer significant during the remainder of the 12-week postdissection period. Our findings were similar in a sensitivity analysis identifying patients who presented with typical symptoms of acute dissection. The risk of stroke after cervical artery dissection unaccompanied by ischemia at time of diagnosis seems to be limited to the first 2 weeks. © 2017 American Heart Association, Inc.

    Full Text Available Aneurysm of gastroduodenal artery (GDA is rare. Most reported cases are due to pancreatitis and atherosclerosis; however, those following pancreatic trauma have not been reported. We encountered GDA aneurysm in a patient of blunt abdominal trauma, who had pancreatic contusion and retroduodenal air on contrast enhanced computed tomography of abdomen. Emergency laparotomy for suspected duodenal injury revealed duodenal wall and pancreatic head contusion, mild hemoperitoneum and no evidence of duodenal perforation. In the postoperative period, the patient developed upper gastrointestinal hemorrhage on day 5. Repeat imaging revealed GDA aneurysm, which was managed successfully by angioembolization. This case highlights, one, delayed presentation of GDA aneurysm after blunt pancreatic trauma and two, its successful management using endovascular technique.

    Full Text Available Unruptured posterior communicating artery (PCOM aneurysms can be difficult to diagnose and, when large (≥ 7mm, represent a substantial risk to the patient. While most unruptured PCOM aneurysms are asymptomatic, when symptoms do occur, clinical manifestations typically include severe headache (HA, visual acuity loss, and cranial nerve deficit. This case report describes an atypical initial presentation of a large unruptured PCOM aneurysm with symptoms mimicking trigeminal neuralgia, without other associated cranial nerve palsies or neurologic deficits. The patient returned to the emergency department four days later with a HA, trigeminal neuralgia, and a new cranial nerve III palsy. After appropriate imaging, she was found to have a large PCOM aneurysm, which was treated with surgical clipping with significant improvement in patient’s symptoms.

    One of the most important complications of Kawasaki disease is the development of giant coronary aneurysms. Risk factors for their development are still not clear. A retrospective analysis was conducted at the National Institute of Paediatrics in Mexico City, Mexico. It included all patients with a diagnosis of acute Kawasaki disease between August, 1995 and August, 2015. Clinical and laboratory findings, as well as echocardiographic measurements, were recorded. Patients with giant coronary aneurysms (z-score⩾10) were compared with the rest of the patients. A value of pKawasaki disease. Of them, 34 developed giant coronary aneurysms during the acute stage of the disease. In the multivariate analysis, patients younger than 1 year, those with a higher duration of illness at the time of diagnosis, and those who received additional intravenous immunoglobulin showed a significantly higher frequency of giant coronary aneurysms. One of the main factors associated with the development of giant coronary aneurysms was the delay in the diagnosis of Kawasaki disease. This finding highlights the importance of maintaining a high suspicion of the disease, which would enable an early diagnosis and prompt treatment and decrease the risk for developing giant coronary aneurysms.

    There are variations in the anatomy of the vertebrobasilar system amongst which the Anterior Inferior Cerebellar Artery-Posterior Inferior Cerebellar Artery (AICA-PICA) variant is thought to have a prevalence of 20-24% (based on retrospective studies). Despite this, aneurysms of the AICA-PICA variant are rare. We present a case of an AICA-PICA aneurysm and discuss its presentation and management, along with a review of literature. We describe the case of a 35 year old female who presented with signs of meningismus. On the basis of radiological imaging it was initially misdiagnosed as a thrombosed arteriovenous malformation (AVM). The patient was eventually discharged with a plan of interval imaging and interventional radiology (if required). The patient presented again with similar signs and symptoms. Re-evaluation of imaging revealed an aneurysm of the AICA-PICA variant which was managed surgically. Aneurysms of the AICA-PICA variant are rare. The radiological features and surgical management represent a unique clinical entity and are discussed below. The prevalence of the AICA-PICA variant might be high but aneurysms in this vessel are rare. The scant knowledge available on this subject makes it a diagnostic difficulty.

    Intra-arterial treatment of aneurysms by redirecting blood flow is a newer method. The redirection is based on a significantly more densely braided wire stent. The stent wall keeps the blood in the lumen of the stent and slows down the turbulent flow in the aneurysms. Stagnation of blood in the aneurysm sac leads to the formation of thrombus and subsequent exclusion of the aneurysm from the circulation. The aim of the study was to evaluate flow diverter device Pipeline for broad neck and giant aneurysm treatment. Fifteen patients with discovered aneurysm of the internal carotid artery were treated between November 2010 and February 2014. The majority of aneurysms of the internal carotid artery were located intradural at the ophthalmic part of the artery. The patients were treated using a flow diverter device Pipeline, which was placed over the aneurysm neck. Treatment success was assessed clinically and angiographically using O'Kelly Marotta scale. Control angiography immediately after the release of the stent showed stagnation of the blood flow in the aneurysm sac. In none of the patients procedural and periprocedural complications were observed. 6 months after the procedure, control CT or MR angiography showed in almost all cases exclusion of the aneurysm from the circulation and normal blood flow in the treated artery. Neurological status six months after the procedure was normal in all patients. Treatment of aneurysms with flow diverter Pipeline device is a safe and significantly less time consuming method in comparison with standard techniques. This new method is a promising approach in treatment of broad neck aneurysms.
