Unprecedented Blog Post Unearths The Confusing Tactics Of MG-132
Among these four patients, three had infarction involving the corona radiata.4 The development of permanent paresis in these three cases was due to the involvement of the pyramidal tract in the corona radiata.4 The fourth patient had an infarction in the brain stem (pontomesencephalic junction). This area would also directly involve the pyramidal tract.4 As one would expect when the pathophysiology of a selleck products syndrome is still debated, there is no consensus on an effective treatment for CWS. Despite various treatments being available and used, it is unclear whether these treatments alter the natural course of the syndrome. Antiplatelets, heparin and measures to elevate BP (such as vasopressors), have been used to treat patients with CWS, it remains uncertain whether any of these therapies are able to change the progression of the syndrome.10 It is thought that by elevating BP, one will be able to reduce distal vessel hypoperfusion, and thereby improving perfusion to the affected areas.11 There have been case series suggesting that dual antiplatelets (aspirin and clopidogrel) may be beneficial, similar to the effect seen in acute coronary syndromes. In a case series including two patients with CWS, it is reported that following the start of dual antiplatelets, there was no progression of symptoms.7 In a case series of four patients, three of the patients who received alteplase were discharged with NIHSS of 0 with no areas of restricted diffusion on MRI. The authors report a possible benefit of thrombolysis in CWS, although they were not able to exclude spontaneous recanalisation in these cases.11 There are various hypotheses related to pathophysiology of CWS, and consequentially no general consensus on treatment options to alter disease progression. There needs to be more research focused on the treatment options which target the various proposed aetiologies.7 Until there are randomised trials it remains unclear whether dual antiplatelet treatment will be of any benefit. Learning points Capsular warning syndrome (CWS) describes recurrent stereotyped lacunar transient ischaemic attacks clustered within a short period of time and is associated with a high risk of developing a completed stroke. While the clinical picture of CWS (and the nomenclature) might suggest an internal capsule involvement, CWS may be caused by an infarct affecting the corticospinal tracts below the internal capsule, such as within the pons. It is not clear whether antiplatelets, heparin or thrombolysis affect the outcome of a completed stroke in patients with CWS. Footnotes Contributors: The case was chosen by TA.
