THROMBUS FORMATION DURING DIRECT PUNCTURE CEREBRAL ANGIOGRAPHY

Thrombus formation during septal puncture

[Mechanism underlying thrombus formation in cerebral infarction].

For thrombus formation, three important factors, blood flow, blood component and blood vessels, have been recognized as Virchow's triad. In cardiogenic embolism with atrial fibrillation, stagnation of blood in the left atrium causes fibrin-rich thrombus. Anticoagulation is the only effective drug for prevention of this type of thrombus. In atherothrombotic and lacunar infarction, injury of endo...

A halo in the heart during coronary angiography: calcified left ventricular aneurysm with thrombus formation

A 74-year-old man presented with chest pain and dyspnoea at the cardiology outpatient clinic. His past medical history included an anterior myocardial infarction in 2008. In the coronary angiogram, a 'halo image' was seen right after the injection of the contrast agent, and it corresponded with the location of the left ventricular aneurysm. A calcified left ventricular aneurysm with mural throm...

Arterial thrombus formation during clinical percutaneous catheterization.

Deposition of thrombotic material on catheters was observed following more than 50% of 93 diagnostic catheterizations. The incidence of deposition of thrombotic material on catheters remaining in the body for more than 1 day was 100%. Polyethylene and siliconized polyurethane catheters were less thrombogenic than Teflon end-occluded catheters. A definite time relationship between the thrombus f...

Rerupture of cerebral aneurysms during angiography.

PURPOSE To assess the incidence of angiography-related rerupture of intracranial aneurysms and to analyze other risk factors of this complication. METHODS Clinical data from 144 patients with acute subarachnoid hemorrhage from ruptured intracranial aneurysm were reviewed retrospectively. In all patients, angiography was done by the transaortic approach. RESULTS The incidence of rerupture ca...
