The authors used daily transcranial Doppler (TCD) evaluation to test the hypothesis that balloon angioplasty is superior to papaverine infusion for the treatment of proximal anterior circulation arterial vasospasm following subarachnoid hemorrhage (SAH). Between 1989 and 1995, 125 vasospastic distal internal carotid artery or proximal middle cerebral artery vessel segments were treated in 52 patients. Blood flow velocities of the involved vessels were assessed using TCD monitoring in relation to the day of treatment with balloon angioplasty or papaverine infusion. Balloon angioplasty and papavarine infusion cohorts were compared based on mean pretreatment velocity and mean posttreatment velocity at 24 and 48 hours using the one-tailed, paired-samples t-test. Balloon angioplasty alone was performed in 101 vessel segments (81%) in 39 patients (75%), whereas papaverine infusion alone was used in 24 vessel segments (19%) in 13 patients (25%). Although repeated treatment following balloon angioplasty was needed in only one vessel segment, repeated treatment following papaverine infusion was required in 10 vessel segments (42%) in six patients because of recurrent vasospasm (p < 0.001). Seven vessel segments (29%) with recurrent spasm following papaverine infusion were treated with balloon angioplasty. Although vessel segments treated with papaverine demonstrated a 20% mean decrease in blood flow velocity (p < 0.009) on posttreatment Day 1, velocities were not significantly lower than pretreatment levels by posttreatment Day 2 (p = 0.133). Balloon angioplasty resulted in a 45% mean decrease in velocity to a normal level following treatment (p < 0.001), which was sustained. The authors conclude that balloon angioplasty is superior to papaverine infusion for the permanent treatment of proximal anterior circulation vasospasm following aneurysmal SAH.

Object. The purpose of this study was to test the hypothesis that balloon angioplasty is superior to papaverine infusion for the treatment of proximal anterior circulation arterial vasospasm following subarachnoid hemorrhage (SAH). Between 1989 and 1995, 125 vasospastic distal internal carotid artery or proximal middle cerebral artery vessel segments were treated in 52 patients. Methods. Blood flow velocities of the involved vessels were assessed by using transcranial Doppler (TCD) monitoring in relation to the day of treatment with balloon angioplasty or papaverine infusion. Balloon angioplasty and papaverine infusion cohorts were compared based on mean pre- and posttreatment velocity at 24 and 48 hours using the one-tailed, paired-samples t-test. Balloon angioplasty alone was performed in 101 vessel segments (81%) in 39 patients (75%), whereas papaverine infusion alone was used in 24 vessel segments (19%) in 13 patients (25%). Although repeated treatment after balloon angioplasty was needed in only one vessel segment, repeated treatment following papaverine infusion was required in 10 vessel segments (42%) in six patients because of recurrent vasospasm (p < 0.001). Seven vessel segments (29%) with recurrent spasm following papaverine infusion were treated with balloon angioplasty. Although vessel segments treated with papaverine demonstrated a 20% mean decrease in blood flow velocity (p < 0.009) on posttreatment Day 1, velocities were not significantly lower than pretreatment levels by posttreatment Day 2 (p = 0.133). Balloon angioplasty resulted in a 45% mean decrease in velocity to a normal level following treatment (p < 0.001), a decrease that was sustained. Conclusions. Balloon angioplasty is superior to papaverine infusion for the permanent treatment of proximal anterior circulation vasospasm following aneurysmal SAH.

Abstract Background The implication of the steroids estradiol, progesterone and testosterone in cerebral vasospasm after aneurysmal subarachnoid hemorrhage (aSAH) has not been comprehensively assessed. In rodents, studies suggested beneficial effects of steroids on cerebral vasospasm after experimental SAH. Studies in humans are warranted, however, a general dilemma of human studies on neuroactive substances is that the brain is not directly accessible and that concentrations in the periphery may not adequately parallel concentrations in the central compartments. In the present study, concentrations of estradiol, progesterone and testosterone in serum and cerebrospinal fluid (CSF) of patients with aSAH were determined. Blood flow velocities in cerebral arteries were measured by transcranial Doppler sonography (TCD). The aim of this study was to evaluate the correlations between the cerebral blood flow velocities and levels of estradiol, progesterone and testosterone in CSF and serum. Results Samples of serum and CSF of 42 patients with aSAH were collected concomitantly daily or every other day via the arterial line and the external ventricular drainage for two weeks after the hemorrhage. Blood flow velocities in the cerebral arteries were determined by TCD. Total estradiol, progesterone and testosterone concentrations were measured by electro-chemiluminescence immunoassay. The strength of correlation was assessed by Spearman’s rank correlation coefficient. The correlation analysis revealed very weak correlations between cerebral blood flow velocities and concentrations of estradiol, progesterone and testosterone levels in both compartments with correlation coefficients below 0.2. Conclusions In humans with aSAH, merely very weak correlations between flow velocities in cerebral arteries and concentrations of estradiol, progesterone and testosterone in serum and CSF were demonstrated. These results suggest a limited influence of the respective steroids on cerebral vascular tone although vasodilatory effects were described in rodent studies. Thus, the implication of steroids in processes of neurological deterioration warrants further clarification.

Abstract BACKGROUND: Cerebral vasospasm (VSP) is a major cause of morbidity and mortality associated with subarachnoid hemorrhage. The current endovascular paradigm for VSP refractory to medical therapy is to perform angioplasty for proximal vessel VSP and vasodilator infusion for distal vessel VSP. OBJECTIVE: To report our experience with a large series of balloon angioplasty for distal VSP refractory to medical therapy in patients with aneurysmal subarachnoid hemorrhage. METHODS: This was a retrospective series of 32 patients with subarachnoid hemorrhage and symptomatic VSP refractory to medical therapy who were treated with balloon angioplasty for distal vessel VSP. Immediate angiographic results, procedure-related complications, and clinical outcomes were assessed. RESULTS: From September 2001 to January 2010, 32 patients with symptomatic VSP refractory to medical therapy underwent angioplasty for distal arterial VSP. There were 26 women (81.3%); patients were 29 to 67 years of age. A total of 175 vessels were angioplastied (95 proximal and 80 distal). The only complication was rupture of an incompletely clipped aneurysm that was treated by immediate coiling and did not result in any clinical worsening. Repeated treatment was needed for 6 arteries (6 of 80, 7.5%). There were no procedure-related symptomatic complications. Good outcomes (modified Rankin Scale score ≤ 2) were observed in 23 of 28 patients (82.1%) with follow-up. CONCLUSION: Balloon angioplasty for distal VSP is safe and effective and decreases the need for repeated intraarterial treatments seen with infusion of vasodilator.

The relevance of steroids on cerebral vasospasm in humans remains unclear although beneficial effects were described in rodent studies. Pathways leading to neurological deterioration linked and unlinked to cerebral vasospasm remain complex and possibly interrelated. Thus, the implication of steroids in cerebral vasospasm or other processes of neurological deterioration warrants further clarification.

Object The calcium antagonist nimodipine has been shown to reduce the incidence of ischemic complications following aneurysmal subarachnoid hemorrhage (SAH). Although most randomized studies have been focused on the effect of the peroral administration of nimodipine, intravenous infusion is an alternative and the preferred mode of treatment in many centers. It is unknown whether the route of administration is of any importance for the clinical efficacy of the drug. Methods One hundred six patients with acute aneurysmal SAH were randomized to receive either peroral or intravenous nimodipine treatment. The patients were monitored for at least 10 days after bleeding in terms of delayed ischemic neurological deficits (DINDs) and with daily measurements of blood flow velocities in the middle cerebral arteries by using transcranial Doppler ultrasonography. Three months after SAH, clinical outcome and new cerebral infarctions according to MR imaging studies were recorded. Results Baseline characteristics (age, sex distribution, clinical status on admission, radiological findings, and aneurysm treatment) did not differ between the treatment groups. There was no significant difference in the incidence of DINDs (28 vs 30% in the peroral and intravenous groups, respectively) or middle cerebral artery blood flow velocities (> 120 cm/second, 50 vs 45%, respectively). Clinical outcome according to the Glasgow Outcome Scale was the same in both groups, and there was no difference in the number of patients with new infarctions on MR imaging. Conclusions The results suggest that there is no clinically relevant difference in efficacy between peroral and intravenous administration of nimodipine in preventing DINDs or cerebral vasospasm following SAH.

OBJECTIVECerebral vasospasm (CV) is a delayed, sustained contraction of the cerebral arteries that tends to occur 3–14 days after aneurysmal subarachnoid hemorrhage (aSAH) from a ruptured aneurysm. Vasospasm potentially leads to delayed cerebral ischemia, and despite medical treatment, 1 of 3 patients suffer a persistent neurological deficit. Bedside transcranial Doppler (TCD) ultrasonography is used to indirectly detect CV through recognition of an increase in cerebral blood flow velocity (CBFV). The present study aimed to use TCD ultrasonography to monitor how CBFV changes on both the ipsi- and contralateral sides of the brain in the first 24 hours after patients have received a stellate ganglion block (SGB) to treat CV that persists despite maximum standard therapy.METHODSThe data were culled from records of patients treated between 2013 and 2017. Patients were included if an SGB was administered following aSAH, whose CBFV was ≥ 120 cm/sec and who had either a focal neurological deficit or reduced consciousness despite having received medical treatment and blood pressure management. The SGB was performed on the side where the highest CBFV had been recorded with 8–10 ml ropivacaine 0.2%. The patient’s CBFV was reassessed after 2 and 24 hours.RESULTSThirty-seven patients (male/female ratio 18:19), age 17–70 years (mean age 49.9 ± 11.1), who harbored 13 clipped and 22 coiled aneurysms (1 patient received both a coil and a clip, and 3 patients had 3 untreated aneurysms) had at least one SGB. Patients received up to 4 SGBs, and thus the study comprised a total of 76 SGBs.After the first SGB, CBFV decreased in 80.5% of patients after 2 hours, from a mean of 160.3 ± 28.2 cm/sec to 127.5 ± 34.3 cm/sec (p < 0.001), and it further decreased in 63.4% after 24 hours to 137.2 ± 38.2 cm/sec (p = 0.007). A similar significant effect was found for the subsequent SGB. Adding clonidine showed no significant effect on either the onset or the duration of the SGB. Contralateral middle cerebral artery (MCA) blood flow was not reduced by the SGB.CONCLUSIONSTo the authors’ knowledge, this is the largest study on the effects of administering an SGB to aSAH patients after aneurysm rupture. The data showed a significant reduction in ipsilateral CBFV (MCA 20.5%) after SGB, lasting in about two-thirds of cases for over 24 hours with no major complications resulting from the SGB.

Spontaneous subarachnoid hemorrhage accounts for 5 to 10 % of all strokes, with a worldwide incidence of 10.5 / 100000 person/year, varying in individual reports from 1.1 to 96 /100000 person/year. Angiographic and autopsy studies suggest that between 0.5% and 5% of the population have intracranial aneurysms. Approximately 30000 people suffer aneurysmal subarachnoid hemorrhage in the United States each year, and 60% die or are left permanently disabled. We report our experience in the surgical treatment of intracranial aneurysms in a six year period, in Belo Horizonte, Minas Gerais, Brazil. We reviewed the hospital files, surgical and out-patient notes of all patients operated on for the treatment of intracranial aneurysms from January 1997 to January 2003. Four hundred and seventy-seven patients were submitted to 525 craniotomies for treatment of 630 intracranial aneurysms. The majority of patients were female (72.1%) in the fourth or fifth decade of life. Anterior circulation aneurysms were more common (94.4%). The most common location for the aneurysm was the middle cerebral artery bifurcation. The patients were followed by a period from 1 month to 5 years. The outcome was measured by the Glasgow Outcome Scale (GOS). At discharge, 62.1% of the patients were classified as GOS 5, 13.9% as GOS 4, 8.7% as GOS 3, 1.7% as GOS 2 and 14.8% as GOS 1.
