Randomized Controlled Trial Comparative Study Clinical Trial
Outcomes of early endovascular versus surgical treatment of ruptured cerebral aneurysms. A prospective randomized study.
This prospective study was conducted to compare the outcomes of surgical clipping and endovascular treatment in acute (<72 hours) aneurysmal subarachnoid hemorrhage (SAH). ⋯ One-year clinical and neuropsychological outcomes seem comparable after early surgical and endovascular treatment of ruptured intracranial aneurysms. The long-term efficacy of endovascular treatment in preventing rebleeding remains open.

Randomized Controlled Trial Multicenter Study Clinical Trial
Effect of triamcinolone acetonide injections on hemiplegic shoulder pain : A randomized clinical trial.
Background and Purpose-Hemiplegic shoulder pain is not uncommon after stroke. Its origin is still unknown, and although many different methods of treatment are applied, none have yet been proved to be effective. We sought to study the efficacy of 3 injections of intra-articular triamcinolone acetonide on pain and arm function in stroke patients with hemiplegic shoulder pain. ⋯ -In the 37 participants included in this study, triamcinolone injections seemed to decrease hemiplegic shoulder pain and to accelerate recovery, but this effect was not statistically significant. Therefore, on the basis of the results of this study, these injections cannot be recommended for the treatment of patients with hemiplegic shoulder pain.

Randomized Controlled Trial Multicenter Study Clinical Trial
Cervene (Nalmefene) in acute ischemic stroke : final results of a phase III efficacy study. The Cervene Stroke Study Investigators.
The goals of the present study were to assess the efficacy and safety of nalmefene (Cervene) in patients with acute (< or =6 hours) ischemic stroke and to investigate the safety of combined recombinant tissue plasminogen activator and nalmefene in a separate subset of patients. Nalmefene, an opioid antagonist with relative kappa receptor selectivity, has shown neuroprotective effects in multiple experimental central nervous system injury and ischemic models. Results from an earlier phase II study in patients with acute ischemic stroke suggested that nalmefene was safe and tolerable and may be effective for patients <70 years old. ⋯ Although nalmefene appears to be safe and well tolerated, this study failed to find any treatment benefit in stroke patients treated within 6 hours.

Randomized Controlled Trial Multicenter Study Clinical Trial
The rtPA (alteplase) 0- to 6-hour acute stroke trial, part A (A0276g) : results of a double-blind, placebo-controlled, multicenter study. Thromblytic therapy in acute ischemic stroke study investigators.
The Thrombolytic Therapy in Acute Ischemic Stroke Study, which started in August of 1991, was designed to assess the efficacy and safety of intravenous rtPA (alteplase) in patients with acute (0 to 6 hours) ischemic stroke. In October 1993 enrollment was halted because of Safety Committee (DMSB) concerns. In December 1993 the time window was changed to 0 to 5 hours, and it was decided to restart enrollment as a separate study (part B). We report here the results of the original study (part A), focusing on evaluating the safety and efficacy of rtPA given between 0 and 6 hours after stroke onset. ⋯ This study found no significant rtPA benefit on any of the planned efficacy end points at 30 and 90 days in patients treated between 0 and 6 hours after stroke onset. These negative results apply to patients treated after 3 hours, because only 15% of the patients were enrolled before 3 hours. The risk of symptomatic intracerebral hemorrhage was increased with rtPA treatment, particularly in patients treated between 5 and 6 hours after onset. These results do not support the use of intravenous rtPA for stroke treatment >3 hours after onset.

Randomized Controlled Trial Clinical Trial
Effect of hypervolemic therapy on cerebral blood flow after subarachnoid hemorrhage : a randomized controlled trial.
Cerebral blood flow (CBF) is reduced after subarachnoid hemorrhage (SAH), and symptomatic vasospasm is a major cause of morbidity and mortality. Volume expansion has been reported to increase CBF after SAH, but CBF values in hypervolemic (HV) and normovolemic (NV) subjects have never been directly compared. ⋯ HV therapy resulted in increased cardiac filling pressures and fluid intake but did not increase CBF or blood volume compared with NV therapy. Although careful fluid management to avoid hypovolemia may reduce the risk of delayed cerebral ischemia after SAH, prophylactic HV therapy is unlikely to confer an additional benefit.
