    MANAGEMENT OF POPLITEAL ARTERY ANEURYSMS

    ANZ JOURNAL OF SURGERY, Issue 10 2006
    Maher Hamish
    Background: Popliteal artery aneurysms (PAA) are the most common peripheral aneurysm and are recognized as ,the silent killer of the leg circulation'. The timing and type of interventions used in their treatment is still controversial. This review examines the published data on the natural history, epidemiology, clinical presentation and management options available. The aim of this study is to try and reach a consensus with regards to the best management of PAA. Method: A systematic review of data in the English published works since 1980. Results: The authors include 53 studies containing 2854 patients with 4291 PAA. Most published data involves retrospective studies and personal experience, with one multicentre study. No randomized controlled studies exist regarding the management of PAA. Conclusions: 1. Although most PAA are of atherosclerotic origin in old patients, trauma, infection and family history are the main causes in young patients. 2. Great vigilance is needed for diagnosis as only approximately five patients are seen each year by a major vascular centre. There is no place for screening programmes to detect PAA. 3. Approximately 45% of patients are asymptomatic at the time of initial diagnosis. Aortic aneurysms are found in 40% and bilateral PAA in 50% of patients. More than 95% of patients are men with a mean age of 65 years and 45% have hypertension. 4. Surgical reconstruction is recommended for all symptomatic and asymptomatic aneurysms larger than 2 cm. Five-year graft patency rates after surgical repair range from 30 to 97%, with 5-year limb salvage ranging from 70 to 98%. Patient survival rates at 5 and 10 years are 75 and 46%, respectively. 5. If carried out carefully, intra-arterial thrombolysis can safely prepare patients presenting with acute ischaemia from occluded PAA, for surgical revascularization to restore distal run-off. 6. Endovascular repair of a PAA is a feasible option, although little evidence is yet available. 7. Lifelong, careful patient surveillance is essential to detect and treat new aneurysms at other sites.

    ENDOVASCULAR REPAIR OF POPLITEAL ARTERY ANEURYSMS: TECHNIQUES, CURRENT EVIDENCE AND RECENT EXPERIENCE

    ANZ JOURNAL OF SURGERY, Issue 6 2006
    Ray Siauw
    Endovascular repair of popliteal artery aneurysms is a new technique, which has emerged as an alternative to open surgical bypass. However, evidence to support its use is limited. We present a review of current literature relevant to this technique. The MEDLINE search terms were popliteal artery, aneurysm, endovascular, endoluminal and stent. Fifty-eight articles were yielded, of which 21 were studies of endovascular repair by implantation of stent or stent graft of true aneurysms of the popliteal artery. There was only one randomized study. Small numbers of endovascular interventions are reported, with variations in study design and endovascular techniques. Long-term follow-up data is lacking; however, early results have been promising with high rates of initial treatment success. Early thrombosis of stent grafts occurs in approximately 10%, but this does not herald limb loss. Endovascular treatment offers potential benefits over traditional surgery, but needs to be studied further with a large-scale multicentre randomized trial. [source]

    Refractory Progression of Coronary Aneurysms, a Case of Delayed Onset Kawasaki Disease as Depicted by Cardiac Computed Tomography Angiography

    CONGENITAL HEART DISEASE, Issue 3 2010
    FACP, Shah Azmoon MD
    ABSTRACT Background., Kawasaki disease (KD) is an immune-mediated vasculitis of unknown etiology with self-limited clinical course that was first described in 1967 by Dr. Tomisaku Kawasaki. It is a disease of early childhood and rare past late adulthood but one that can have detrimental consequences when there is a delay in diagnosis and treatment. Cardiovascular complications causing increased morbidity and mortality may include coronary artery aneurysms, myocardial infarction, heart failure, arrhythmias, and peripheral artery occlusion. Case Presentation., Here, we present an atypical case of delayed onset KD in a young teenager. DS had visited three different emergency departments during the course of 2 weeks for unrelenting fevers. Despite multiple treatment protocols including immunoglobulin, steroids, and tumor necrosis factor-alpha antagonists, he continued to have progression of cardiovascular complications. While echocardiographic findings were suspicious for cardiac complications, a cardiac computed tomography (CT) angiography was able to clearly distinguish giant coronary aneurysms. Conclusion., Without prompt therapy, fever and manifestations of acute inflammation can last for several weeks to months with increased risk toward complications. The incidence of coronary artery aneurysms has been noted to be 25% in untreated patients with a mortality rate of up to 2%. Using low-dose protocols along with high spatial and temporal resolution of cardiac CT angiography may provide a useful and complimentary imaging modality in accurate diagnosis and follow-up of patients with KD.

    Migraine and Raynaud Phenomenon: Possible Late Complications of Kawasaki Disease

    HEADACHE, Issue 3 2002
    Cris S. Constantinescu MD
    Migraine and Raynaud phenomenon often coexist and may reflect similar vascular reactions. Both have been associated with vascular endothelial cell dysfunction. Kawasaki disease is a systemic vasculitis of unknown etiology that affects children and may lead to the formation of coronary artery aneurysms. Endothelial cell dysfunction has been demonstrated late in Kawasaki disease and is not restricted to coronary vessels. We report the case of a patient who developed typical migraine with aura and Raynaud phenomenon at the age of 14, 12 years after onset of Kawasaki disease. His migraine responded well to pizotifen, and both migraine and Raynaud phenomenon improved after initiation of treatment with valproic acid. We postulate that both migraine and Raynaud phenomenon in this case represent late consequences of Kawasaki disease and result from extracoronary endothelial dysfunction. [source]

    Characteristics and management of splenic artery aneurysms in adult living donor liver transplant recipients

    LIVER TRANSPLANTATION, Issue 11 2009
    Deok-Bog Moon
    Splenic artery aneurysms (SAAs), occurring in 7% to 17% of patients with cirrhosis, often result in catastrophic rupture after liver transplantation. We had experienced 3 cases of ruptured SAAs after adult living donor liver transplantation (LDLT), and we then performed this study to find risk factors for coexisting SAAs in liver transplant candidates with cirrhosis and to propose ideal approaches for them. Preoperative and postoperative computed tomography angiograms and axial views were reviewed for 310 adult LDLT recipients who had cirrhosis from January 2004 to August 2005. The recorded variables were the preoperative diagnosis, the presence of SAA and its characteristics, the splenic artery (SA) diameter, and the presence and size of portosystemic collaterals. Devastating SAA rupture accompanied by hypovolemic shock occurred on postoperative days 6, 82, and 8, respectively, and it was treated emergently by embolization in cases 1 and 2 and by splenectomy in case 3. Cases 1 and 3 recovered well, but case 2 died of an unrelated cause with a long hospital stay. The incidence of SAA during the study period was 14.2% (44/310), and the size was 16.6 ± 5.7 mm. Most SAAs were single (70.6%, 31/44) and were located in the distal one-third of the SA (82.4%, 36/44). Large portosystemic collaterals demonstrating longstanding severe portal hypertension were significantly correlated with the occurrence of SAAs. Nine patients with SAAs were preventively treated by proximal ligation (n = 4) intraoperatively and by embolization (n = 5) 1 day before or after LDLT. No patient showed severe postembolization syndrome. In conclusion, a careful preoperative evaluation of SAAs by high-resolution 3-dimensional computed tomography in liver transplant candidates, especially in those showing large portosystemic collaterals, is merited. Preventive treatment should be encouraged regardless of the size in order to avoid severe morbidity and mortality related to SAA rupture, and methods such as radiological and surgical interventions need to be individualized according to the location and number of SAAs.

    Inflammatory pulmonary nodules in Kawasaki disease

    PEDIATRIC PULMONOLOGY, Issue 2 2003
    Alexandra F. Freeman MD
    Abstract Symptomatic pulmonary manifestations of Kawasaki disease (KD) are uncommon. However, epidemiologic, radiologic, and histologic studies have indicated that respiratory symptoms and findings occur in KD and suggest that the KD agent may have a respiratory portal of entry. We report on three young infants with KD who developed pulmonary nodules, in addition to coronary artery aneurysms. Two patients had pathologic specimens available, one from biopsy and the other from autopsy. The nodules had predominantly mononuclear cell infiltrates, which were within the lung parenchyma and infiltrating vessel walls. Immunohistochemical studies of the nodules, using antibodies to common leukocyte antigen (LCA) and factor VIII-related antigen, confirmed the inflammatory nature of the lesions and showed capillary proliferation. IgA plasma-cell infiltration was observed in the nodule, consistent with previous KD findings of IgA plasma-cell infiltration in the vessel walls, kidneys, pancreas, and upper respiratory tract. The two patients with nonfatal KD were treated with intravenous immunoglobulin and aspirin, with resolution of the nodules. We propose that when pulmonary involvement occurs in KD, it ranges from subclinical interstitial micronodular infiltrates to larger inflammatory pulmonary nodules. These pulmonary infiltrates and nodules likely reflect the host response to the etiologic agent of KD, and may resolve with the disease process. Recognition of this pulmonary complication of KD may enable cautious observation of such lesions for spontaneous resolution. Pediatr Pulmonol. 2003; 36:102,106. © 2003 Wiley-Liss, Inc. [source]

    Treatment of internal iliac artery aneurysms: single-centre experience

    ANZ JOURNAL OF SURGERY, Issue 4 2009
    Nikolaos Tsilimparis
    Abstract Background:, The aim of the present study was to analyse the short-term results of treatment of internal iliac artery aneurysms (IIAA). Methods:, In a prospective single-centre cohort study all patients with IIAA (symptomatic or maximal diameter ,30 mm) were evaluated for endovascular repair, which included coil embolization of the run-off vessels and coverage of the orifice of the IIAA with a stent graft. Open repair was performed with aneurysm excision or aneurysmorrhaphy. Outcome criteria were technical and clinical success and complications of treatment. Results:, In a period of 40 months 11 patients underwent operation for 12 IIAA. Nine aneurysms were repaired endovascularly and three with open repair. Coil embolization was routinely performed in all cases. At a median follow up of 18 months, technical and clinical success was 100%. Major complications included two early limb thromboses, a contrast-agent-induced nephropathy, and an intraoperative ureteric injury. Conclusion:, Despite the limited number of patients, the present series, with good short-term results, further supports the trend towards endovascular repair of suitable IIAA. [source]

    Surgical management of extracranial carotid artery aneurysms

    ANZ JOURNAL OF SURGERY, Issue 4 2009
    Anwar S. Choudhary
    Abstract Extracranial carotid artery aneurysms are uncommon and not much is known about them. The purpose of this study is to report the authors' surgical experience and present a review of this entity. This single institution experience shows that resection of these aneurysms and restoration of flow can be accomplished using a number of surgical techniques with relatively low morbidity and mortality. Endovascular techniques are also increasingly being considered in the repair of these aneurysms, although long-term data from such techniques are not currently available. [source]

    HLA,E gene polymorphism associated with susceptibility to kawasaki disease and formation of coronary artery aneurysms

    ARTHRITIS & RHEUMATISM, Issue 2 2009
    Y.-J. Lin
    Objective Kawasaki disease (KD) is a pediatric systemic vasculitis of unknown cause for which a genetic influence is supposed. The purpose of this study was to identify possible genetic variants in the major histocompatibility complex (MHC) region that are associated with KD and the development of coronary artery aneurysms (CAAs) in a Taiwanese population. Methods The 168 genetic variants covering the MHC locus were analyzed in an association study of a Taiwanese cohort of 93 KD patients and 680 unrelated healthy children matched for sex and age with the study patients. Results Eleven single-nucleotide polymorphisms (SNPs) were associated with the occurrence of KD. The SNP located at the 3,-untranslated region of HLA,E (rs2844724) was highly associated (P < 1 × 10,7). In addition, the frequency of the C allele was higher in KD patients without CAAs than in controls (P < 0.001) due to a significantly increased frequency of the CC and CT genotypes. Plasma levels of soluble HLA,E were significantly higher in KD patients than in controls regardless of the presence of CAAs. Furthermore, there was a trend toward higher plasma levels of soluble HLA,E in KD patients with the CT and TT genotypes of the HLA,E gene polymorphism. Conclusion Our results suggest that the HLA,E gene polymorphism may play a role in the pathogenesis of KD. [source]

    Nationwide study of the outcome of popliteal artery aneurysms treated surgically

    BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 8 2007
    H. Ravn
    Background: The aim was to study the epidemiology and outcomes of popliteal artery aneurysm (PA) treated surgically. Methods: Among 110 000 procedures registered prospectively in the Swedish Vascular Registry (Swedvasc), there were 717 primary operations for PA among 571 patients. Patient records were reviewed and data validated against other registries. Results: The median age of the patients was 71 years; 5·8 per cent were women. Among 264 legs treated urgently, 235 had acute ischemia and 24 had rupture. Of patients with unilateral PA, 28·1 per cent had an aortic aneurysm, 8·4 per cent an iliac aneurysm and 9·4 per cent a femoral aneurysm. Extra-popliteal aneurysms were more common when the PAs were bilateral (P = 0·004). The rate of limb loss within 1 year of operation was 8·8 per cent; 12·0 per cent for symptomatic and 1·8 per cent for asymptomatic limbs (P < 0·001). Risk factors for amputation were symptomatic disease, poor run-off, urgent treatment, age over 70 years, prosthetic graft and no preoperative thrombolysis when the ischaemia was acute. Amputation rates decreased over time (P = 0·003). Crude survival was 91·4 per cent at 1 year and 70·0 per cent at 5 years. Conclusion: Multiple aneurysm disease was common when PAs were bilateral. Preoperative thrombolysis of acute thrombosis and the use of vein grafts for bypass improved outcome. Copyright © 2007 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.
