1/60. Flank ulcer in a patient with primary antiphospholipid syndrome.A 32-year-old woman had a recurrent shallow ulcer on the flank. A biopsy specimen showed thromboses in the dermal vessels and she was found to have circulating antiphospholipid antibody with no associated systemic disease. A clean ulcer developed on the flank of a patient with primary antiphospholipid syndrome is considered to be a rarely encountered/unusual presentation of this syndrome.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/60. Livedoid vasculitis: a manifestation of the antiphospholipid syndrome?Livedoid vasculitis, otherwise known as segmental hyalinizing vasculitis or livedo reticularis with summer ulceration, is a chronic disease with lesions affecting the feet and lower legs. Early lesions show petechiae, but characteristic features are recurrent, bizarrely shaped ulcers that heal to leave hyperpigmentation and atrophie blanche. The aetiology of the disorder is unknown, but the histology shows fibrin deposition within both the wall and lumen of affected vessels. The absence of a sufficient perivascular infiltrate or leucocytoclasia argues against a vasculitis, being more in keeping with a thrombo-occlusive process. Four patients with livedoid vasculitis with ulceration are described, all of whom had associated raised anticardiolipin antibodies but no other evidence of systemic disease. We suggest that livedoid vasculitis may be a manifestation of the antiphospholipid syndrome and recommend that all patients are screened for this. We also discuss treatment options for this often resistant condition.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/60. Cutaneous papules and nodules in the diagnosis of the antiphospholipid syndrome.Of 11 patients with primary or secondary antiphospholipid syndrome (APS), four exhibited papules or nodules on the finger, sole or leg as the initial cutaneous manifestation. Histological examination demonstrated thrombosed vessels or vessels containing organized thrombi in the dermis or in the subcutaneous fat tissue. Cutaneous papules and nodules should be recognized as skin manifestations of APS. Screening tests for antiphospholipid antibodies and lupus anticoagulant are required in patients with cutaneous papules or nodules of unknown aetiology. In cases of positive antiphospholipid antibodies and/or lupus anticoagulant, histological examination is critical in the establishment of the diagnosis of APS.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
4/60. Catastrophic arterial reactivity during primary antiphospholipid syndrome--a case report.Arterial reactivity leading to acute thrombosis at the site of a needle stick injury has never been described during antiphospholipid syndrome. The authors report a case characterized by a succession of thrombotic events occurring during or immediately after arterial angiographies or arterial surgery, in which catastrophic arterial reactivity can be strongly suspected. In this particular patient, it can be postulated that damage to the endothelial cells of the vessels injured during manipulation may have precipitated or aggravated the preexisting susceptibility to thrombosis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/60. Primary antiphospholipid syndrome with moyamoya-like vascular changes.We describe a young girl with antiphospholipid syndrome (APS) and moyamoya-like cerebrovascular changes which reversed after anticoagulation. Although there was a risk of hemorrhage from collateral vessels, we speculate that this treatment may have prevented progression of the vascular abnormalities, while resolution of the thrombus resulted in improved cerebrovascular circulation.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/60. Case report: Hepatic involvement in antiphospholipid syndrome.Three cases of hepatic involvement in antiphospholipid syndrome are described. One patient had catastrophic antiphospholipid syndrome with haemorrhages and necrosis in the liver parenchyma. The second patient had blood clots in the small hepatic vessels. The third patient had autoimmune hepatitis type I associated with antiphospholipid syndrome. Other possible hepatic manifestations of antiphospholipid syndrome are also discussed.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/60. Acute myocardial infarction in a patient with anomalous left coronary artery origin and primary antiphospholipid syndrome.Anomalous left main coronary artery (LMCA) originating from the right coronary sinus and running between the aorta and pulmonary trunk is a rare congenital condition. Although this disease is known to be associated with myocardial infarction and sudden death, the precise mechanism is uncertain. A 14-year-old male with this anomaly developed myocardial infarction during exercise complicated by primary antiphospholipid syndrome. He was admitted to hospital with persistent chest pain and sudden cardiac collapse that occurred while he was running. cardiac catheterization demonstrated a narrowed segment in the LMCA and impaired blood flow, prompting a diagnosis of extensive anterior myocardial infarction. Emergency bypass surgery was performed using a single saphenous vein graft to the left anterior descending artery. Postoperative angiography showed the presence of an anomalous LMCA arising from the right sinus of valsalva and running between the great vessels. The aortic samples were pathologically normal. He was discovered to also have primary antiphospholipid syndrome and was discharged without symptoms after warfarin therapy. Complicated primary antiphospholipid syndrome may trigger myocardial infarction in asymptomatic patients with this type of coronary anomaly.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/60. Widespread cutaneous necrosis occurring in association with the antiphospholipid syndrome: a report of two cases.The antiphospholipid syndrome is an acquired prothrombotic state where thrombosis and/or pregnancy loss is related to the presence of antiphospholipid antibodies. Cutaneous necrosis secondary to intravascular thrombosis of small dermal vessels is a recognized but rare association with antiphospholipid syndrome. We report two patients with high circulating levels of anticardiolipin antibodies who developed widespread cutaneous necrosis as the first clinical manifestation of the antiphospholipid syndrome. The exact mechanism by which antiphospholipid antibodies mediate thrombosis is uncertain; however, proposed mechanisms of activity include endothelial cell activation, altered endothelial production of prostacyclin, activation of platelets, and modulation of the protein c and S pathways.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/60. Cerebral blood flow and glucose metabolism in multi-infarct-dementia related to primary antiphospholipid antibody syndrome.The primary antiphospholipid antibody syndrome (PAPS) has been described in patients with a history of fetal loss, thrombocytopenia and arterial or venous thrombosis. In PAPS, a prothrombotic state is mediated by antiphospholipid antibodies (aPLs) leading to disseminated thromboembolic vascular occlusion. Today, the presence of aPLs in the serum is considered as a distinct risk factor for recurrent stroke in young adults. Some PAPS patients develop a multi-infarct-syndrome with a stepwise decline of higher cortical functions. We report on a 55-year-old man suffering from progressive dementia and PAPS, in whom cerebral glucose metabolism and blood flow were examined by positron emission tomography (PET). Cerebral atrophy and moderate signs of leukaraiosis were detected in magnetic resonance imaging (MRI), whereas the PET scans showed a considerable diffuse impairment of cortical glucose metabolism combined with a reduced cerebral perfusion in the arterial border zones. These findings indicate that PAPS-associated vascular dementia is accompanied by a cortical neuronal loss, presumably caused by a small-vessel disease with immune-mediated intravascular thrombosis. This case shows that pathological findings in PAPS are congruent to cerebral changes of metabolism and blood flow in systemic lupus erythematosus (SLE).- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/60. Small vessel thrombosis without major thrombotic events in systemic lupus erythematosus patients with antiphospholipid syndrome.antiphospholipid syndrome has been defined by the presence of antiphospholipid antibodies or lupus anticoagulant in association with certain clinical events, including recurrent arterial or venous thromboses and recurrent fetal loss. It comprises two separate clinical entities: simple, characterized by large vessel occlusions, and catastrophic, with multiple occlusive events predominantly affecting small vessels. Three patients with systemic lupus erythematosus and permanently increased IgG anticardiolipin antibody levels are being described. Only postmortem histopathological examination revealed microangiopathic thrombotic changes in different organs, which were clinically silent in early stages of the disease and misinterpreted later in its course because of a peculiar clinical picture. All patients presented features of catastrophic antiphospholipid syndrome in the final stage of the disease.- - - - - - - - - - ranking = 6keywords = vessel (Clic here for more details about this article) |
