In Interstitial defect, atom occupies the interstitial space of the lattice structure of solid crystal. In Substitutional defect, the foreign atom occupies only the lattice site of a crystalline solid. Interstitial defect may occur by the atoms of either same solid (called self-interstitial) or foreign material. Substitutional defect is always caused by foreign atoms.
In addition, this entity should be considered in cases of unanticipated arterial occlusive disease of the central nervous system, extremities, mesenteric vessels, or cardiac tree. The defects that are responsible for hypercoagulability can be divided into inherited defects and acquired forms.Table 1 also includes noncoagulant factors. Before 1993, the chance of discovering a coagulation abnormality in patients with traditional hypercoagulability was as low as 5% to 15%.n addition, this entity should be considered in cases of unanticipated arterial occlusive disease of the central nervous system, extremities, mesenteric vessels, or cardiac tree.
