Relation between severity of cerebral small vessel disease and pulsatility index of internal carotid artery in small vessel occlusion

Clinical Neurology and Neurosurgery
The total small vessel disease (SVD) score, calculated using magnetic resonance imaging (MRI), is used to assess the risk of cerebral infarction. Stroke patients with total SVD scores of three or higher are reported to have a significantly increased risk of recurrent stroke.

An in vitro model to mimic the thrombotic occlusion of small vessels in catastrophic antiphospholipid syndrome (CAPS)

Lupus, 2019
Platelet activation and decrease in platelet count characterize the development of the most feared form of antiphospholipid syndrome (APS), i.e. catastrophic APS (CAPS). We aimed to assess if immuno-affinity purified anti-β2-glycoprotein I (aβ2GPI) antibodies enhance platelet activation inducing a significant flow obstruction in a platelet function ...

Acute Arterial Occlusions of the Small Vessels of the Hand and Forearm: Treatment with Regional Urokinase Therapy

Journal of Vascular and Interventional Radiology, 1999
Arterial occlusions of the small vessels of the forearm and hand may have the same consequences as arterial occlusions in the distal lower extremity. There is limited reported experience with the regional thrombolytic therapy in this setting. The authors reviewed their experience with thrombolytic therapy in acute and subacute arterial occlusions of ...

Predictors of Neurologic Deterioration in Patients with Small-Vessel Occlusion and Infarcts in the Territory of Perforating Arteries

Journal of Stroke and Cerebrovascular Diseases, 2014
It is difficult to predict neurologic deterioration in patients with small-vessel occlusion (SVO), that is, small infarcts in the territory of cerebral perforating arteries.We reviewed 110 patients with SVO who were admitted to our hospital. We divided them into groups with (n = 32, group 1) and without deterioration (n = 78, group 2) and evaluated ...

Variations in small blood vessel hematocrits produced in hypothermic rats by micro-occlusion

Microvascular Research, 1968
Abstract The microcirculation was studied in the mesocecum of hypothermic rats. When capillaries of different types were compressed partially with a microneedle, there was a slowing of the blood flow and a striking fall in the hematocrit. It was possible to vary the hematocrit in the compressed vessel at will by varying the degree of compression. The

Small vessel occlusion in acute acalculous cholecystitis.

Surgery, 1992
Ischemia is one mechanism implicated in the pathogenesis of acute acalculous cholecystitis. Gallbladder specimen arteriography was performed to define the comparative status of cystic artery runoff in the macroscopically normal gallbladder (n = 10), in acute gallstone-associated cholecystitis (n = 10), and in acute acalculous cholecystitis (n = 7 ...

Abstract WP560: Cerebral Small Vessel Disease is Associated With Poor Collateral Recruitment in Large-Vessel Occlusive Stroke

Stroke, 2019
Introduction: Cerebral small-vessel disease (SVD) is associated with increased stroke risk and poor stroke outcomes. We aimed to evaluate if chronic SVD burden is associated with poor recruitment of collaterals in large-vessel occlusive stroke. Methods: Consecutive patients with MCA±

Small skin blood vessel occlusions by cryoglobulin aggregates in ulcerative lesions in IgM‐IgG cryglobulinemia

Journal of Cutaneous Pathology, 1982
The skin biopsy specimens from six patients with primary mixed IgM‐IgG cryoglo‐bulinemia were examined by immunofluorescence, light and electron microscopy. The biopsy taken from the involved skin of one patient with leg ulcers revealed small blood vessel occlusions by cryoglobulin aggregates.

Time Window for Induced Hypertension in Acute Small Vessel Occlusive Stroke With Early Neurological Deterioration

Stroke
BACKGROUND: Therapeutic-induced hypertension treatment (iHTN) is helpful for alleviating early neurological deterioration (END) in acute small vessel occlusive stroke.
