Urinary Nitrogen

✓ Oxygen consumption carbon dioxide production , urinary nitrogen excretion, respiratory quotient, resting energy expenditure (REE), %REE, and the consumption rates of carbohydrate, fat, and protein (%CHO, %Fat, %Prot, respectively) were determined pre- and postoperatively by indirect calorimetry in 13 patients with ruptured intracranial aneurysms and 11 patients with hypertensive intracerebral hemorrhage in the acute stage. The preoperative urinary nitrogen excretion, respiratory quotient, REE, and %REE were, respectively (mean ± standard deviation): 171 ± 46 ml/min, 203 ± 56 ml/min, 10.3 ± 1.7 gm/day, 0.84 ± 0.01, 1397 ± 389 Cal/day, and 129% ± 8%. The values for REE, and %REE were all increased above normal levels. The %Prot was increased to 26.1% ± 9.1%. In the postoperative period, the urinary nitrogen excretion, REE, and %REE significantly increased to: 186 ± 44 ml/min, 229 ± 56 ml/min, 14.8 ± 2.9 gm/day, 1557 ± 384 Cal/day, and 141% ± 21%, respectively. The %Fat and %Prot also increased significantly, but the %CHO significantly decreased. Preoperatively, in the patients with ruptured intracranial aneurysms, there was a greater increase in %Prot in eight patients classified (according to Fischer) as having a Group 3 or 4 subarachnoid hemorrhage (SAH) on computerized tomography than in five patients classified as having a Group 1 or 2 SAH. In summary, increased metabolic expenditure, especially increased catabolism of protein and fat, is characteristic of accompanying hemorrhagic cerebrovascular disease, and there is an increase in consumption of fat and protein in the postoperative period. Lack of precise knowledge about the cause and consequences of these metabolic responses makes it impossible at present to judge the optimal extent of nutritional replacement. The hypermetabolic state should be taken into consideration when caring for these patients as it may cause weight loss, poor wound healing, and susceptibility to infection.

✓ An analysis of 3000 ruptured intracranial aneurysms revealed 58 cases in patients under the age of 19 years. There was a striking incidence of aneurysms of the carotid termination and anterior cerebral complex, accounting for 43 of 58 cases, and of these 20 involved the terminal portion of the carotid artery. Vasospasm occurred slightly less often than in adults and infarction was only seen in one postmortem examination. The surgical mortality in alert patients was 7% whereas in a comparable bedrest group it was 38%. This good tolerance to surgery was evident whether intracranial operation or carotid ligation was used, but the surgical method was not randomly allocated.

✓ In the 5-year period from 1978 to 1983, 1076 patients with ruptured intracranial aneurysms were admitted to the six neurosurgical departments in Denmark and were entered in a prospective consecutive study conducted by the Danish Aneurysm Study Group. The patients were followed with 3-month and 2-year examinations or to death. A total of 133 patients suffered at least one rebleed after their initial hemorrhage during their first stay in the neurosurgical department; these patients had a mortality rate of 80% compared to 41 % for patients without a rebleed (p < 0.0001). During the first 2 weeks after the initial insult, 102 rebleeds were registered. The daily rate of rebleeds during these 2 weeks, calculated using a life-table method, varied from 0.2% to 2.1%. The rebleed rate during the first 24 hours (Day 0) was 0.8%, and the maximum risk of rebleeding was observed between Day 4 and Day 9. Significantly fewer rebleeds were reported in patients with good clinical grades (Grades 1 to 3, Hunt Grades I and II) compared to those with poor clinical grades (Grades 4 to 9, Hunt Grades III to V: p < 0.001).

✓ A rapid fluorometric assay technique has been utilized to assess the degree of fibrinolytic inhibition in 20 patients with ruptured intracranial aneurysms treated with epsilon-aminocaproic acid (EACA). This method quantitates the available plasminogen activity (APA) of plasma, and has proven to be a reliable means of monitoring antifibrinolytic therapy. Determination of the plasma APA also permits correlation of the level of fibrinolytic activity with putative complications of EACA therapy. Normal control plasma APA was 3.1 ± 0.7 CTA units/ml, but in patients with subarachnoid hemorrhage (SAH), pretreatment fibrinolytic activity was supranormal at 3.78 ± 0.88 CTA units/ml. During continuous intravenous administration of EACA (1.5 gm/hr) in patients with SAH, the plasma fibrinolytic activity was decreased to 0.9 ± 0.31 CTA units/ml. A case is described which exemplifies the use of this assay. In addition, an approach to monitoring antifibrinolytic therapy using the plasma APA is proposed.

✓ A clinical trial of epsilon-aminocaproic acid (EACA) in preventing recurrent hemorrhage from intracranial arterial aneurysms is reported. Previous reports were reviewed, and their results concerning antifibrinolytic agents were inconclusive in establishing their efficacy. One hundred patients with documented ruptured intracranial aneurysms were admitted to this study within 48 hours of the initial hemorrhage: 45 patients received 36 gm of EACA/day, with 11 documented rebleeds and one suspected rebleed; 55 patients did not receive EACA, and there were four documented rebleeds and one suspected rebleed. No benefit was seen from the use of EACA.

✓ In a retrospective study of 44 patients with verified ruptured intracranial aneurysms, the results of radionuclide cerebral perfusion scintigraphy (dynamic brain scanning) and the presence or absence of arteriographic spasm were correlated with the clinical outcome. The data indicated that patients with normal dynamic scans had a better outcome as a group and following intracranial surgery than those in whom perfusion was reduced. Patients with normal perfusion had a higher incidence of preoperative rebleeding from their aneurysms, while patients with reduced perfusion had a higher incidence of infarction, especially after intracranial surgery. There was no correlation between the presence or absence of arteriographic spasm and the results of the dynamic scans, and no correlation between the presence or absence of spasm and the outcome of the group as a whole. However, in some individual cases with severe spasm, reduced perfusion on the dynamic scan and a poor outcome were noted. It was concluded that the results of the dynamic scan correlated better with eventual patient outcome than the presence or absence of arteriographic spasm. It is therefore suggested that patients in Grades I and II with normal dynamic scans be operated on promptly to prevent rebleeding, and that surgery in patients in Grades I and II with abnormal dynamic scans be delayed until the dynamic scan returns to normal.

✓ Damage to the olfactory nerve during frontotemporal approach to the basal cisternal region has not previously been investigated in a quantified manner. In this retrospective study of 25 patients operated on for ruptured intracranial aneurysms via the frontotemporal route, 22 patients suffered postoperatively from anosmia ipsilateral to the side of surgery. This complication most often goes unrecognized by the patient as well as the physician, and attention should be drawn to it because of its widespread occurrence. This investigation demonstrates a high incidence of anosmia (24 (88.9%) of 27 surgical sides) occurring ipsilateral to the frontotemporal approach in aneurysm surgery. Recovery after traumatic anosmia has been recorded up to 5 years after injury.1 Nevertheless, the authors believe that the damage is permanent when lasting 35 months or longer.

Object. During a 5-year period 317 patients presenting with aneurysmal subarachnoid hemorrhage were successfully treated by coil embolization within 30 days of hemorrhage. The authors followed patients to assess the stability of aneurysm occlusion and its longer-term efficacy in protecting patients against rebleeding.Methods. Patients were followed for 6 to 65 months (median 22.3 months) by clinical review, angiography performed at 6 months posttreatment, and annual questionnaires. Stable angiographic occlusion was evident in 86.4% of small and 85.2% of large aneurysms with recurrent filling in 38 (14.7%) of 259 aneurysms. Rebleeding was caused by aneurysm recurrence in four patients (between 11 and 35 months posttreatment) and by rupture of a coincidental untreated aneurysm in one patient. Annual rebleeding rates were 0.8% in the 1st year, 0.6% in the 2nd year, and 2.4% in the 3rd year after aneurysm embolization, with no rebleeding in subsequent years. Rebleeding occurred in three (7.9%) of 38 recurrent aneurysms and in one (0.4%) of 221 aneurysms that appeared stable on angiography.Conclusions. Periodic follow-up angiography after coil embolization is recommended to identify aneurysm recurrence and those patients at a high risk of late rebleeding.

✓ The authors report their experience with the use of an antifibrinolytic agent and hypotensive drugs in the prevention of rebleeding from recently ruptured intracranial aneurysms and conclude that both measures are of suggestive value. With further refinement in these techniques an additional reduction of early rebleeding may be expected. Secondary cerebral vasospasm remains the major obstacle to early recovery and definitive surgery for ruptured intracranial aneurysms.

✓ The authors have analyzed a total of 96 consecutive cases in which vasospasm followed subarachnoid hemorrhage (SAH). The SAH was caused by ruptured intracranial aneurysm or developed after aneurysm surgery. Usually at least 4 days elapsed between SAH and the onset of vasospasm. Vasospasm subsided an average of 2 weeks after onset. Of 68 patients with preoperative vasospasm, eight died due to cerebral edema resulting from ischemia, and 49% of the survivors had neurological deficits. Preoperative vasospasm was not aggravated by surgical intervention when operations were carried out more than 7 days after the onset of vasospasm. Postoperative vasospasm was found in 25 of 52 patients who underwent operation within 1 week after SAH (excluding cases in Grade V). Five of these patients died, all of whom underwent surgery between the fourth and seventh day after SAH (the day of SAH was counted as the first day). There were no deaths among 20 patients operated on within the first 3 days after SAH. Postoperative vasospasm was always mild in these cases, when it occurred, probably because blood clot or blood-stained cerebrospinal fluid was removed by operative procedures. In all cases, 4 to 11 days elapsed between the last SAH and the onset of postoperative vasospasm regardless of the timing of surgery.

✓ Twenty-eight cases of communicating hydrocephalus after subarachnoid hemorrhage (SAH) due to ruptured intracranial aneurysms are reported. The relationship between the incidence of this complication and the various clinical features of SAH is discussed. The findings of RISA cisternography have little relationship to the findings of pneumoencephalography or the results of shunting procedures. The availability and value of echoencephalography in treating such patients is emphasized.
