[Medline]. 1999 Nov. 91(5):761-7. Regarding the hemodynamic response, the relationship between the initial high blood pressure on admission and DNID was unclear. Some investigators have advocated endovascular or surgical treatment of all aneurysms less than 10 mm if age is less than 50 years, in the absence of contraindications. Berge J, Biondi A, Machi P, Brunel H, Pierot L, Gabrillargues J, et al. /viewarticle/939129 The anatomical characterization and morphology of unruptured aneurysms are not readily standardized, however. We suggest the optimal cutoff points of blood pressure below the initial baseline as Δ SBP of 36 mmHg, Δ DBP of 27 mmHg, and Δ MAP of 32 mmHg. Aneurysmal rupture, the principal surgical complication, may be avoided with induced hypotension, CSF drainage, diuretics, hyperventilation, and use of minimal brain retraction. Flow-Diverter Silk Stent for the Treatment of Intracranial Aneurysms: 1-year Follow-Up in a Multicenter Study. These results allow balance baseline data between the two groups that facilitate avoiding systematic error and identifying a more accurate optimal target range of hemodynamic parameters and ETCO2 for preventing DNID after cerebral aneurysm clipping in SAH patients.

An increased blood flow through the artery puts undue pressure on it which then weakens it over time. Triple-H therapy is a common measure to treat cerebral vasospasm.8, 9 However, the time to start taking hypertension is still controversial. 1979501-overview This bulging/aneurysm is most common in aorta or brain. Managing blood pressure can also minimize the risk of an aneurysm. AJNR Am J Neuroradiol. Most people have weak spots in the lining of their arteries and, fortunately, most aneurysms are small, cause no symptoms and do not rupture. In our study, the initial mean of MAP in the DNID group was higher than that in the non-DNID group (109.5 ± 10.6 vs 89.2 ± 12.2 mmHg; ), similar to previous studies. Infectious aneurysms are friable, with an increased propensity for hemorrhage. Although the initial SBP and DBP were not reported in the previous studies, we found a significant trend of higher SBP and DBP in the DNID group (152.9 ± 18.3 vs 129.8 ± 25.7; and 87.9 ± 14.0 vs 68.9 ± 10.9; , respectively) that may be relative risk factors for DNID. Optimal timing of aneurysm surgery depends on the clinical status of the patient and associated factors. Yi, Y. Ko, and K.-M.

Delayed surgery (ie, 10-14 d after SAH) may be considered for large aneurysms in difficult locations or for candidates in poor clinical condition. Intraoperative hypotension seems to be indicated as a risk factor, but it remains a controversial issue with varying low-blood pressure levels accepted. For posterior communicating, vertebrobasilar/posterior cerebral, or basilar tip aneurysms less than 10 mm, the risk of rupture over 7.5 years approximated 2%, with all other locations harboring a risk of almost 0%. Early versus late intracranial aneurysm surgery in subarachnoid hemorrhage. Berry aneurysms are seen in patients with chronic uncontrolled hypertension, which can be prevented by strict BP control.

Treatment in other cases may include surgical procedures such as: J Neurosurg. Could late rebleeding overturn the superiority of cranial aneurysm coil embolization over clip ligation seen in the International Subarachnoid Aneurysm Trial?. Regarding blood pressure measurement, the oscillometric device was used for monitoring and it recorded every five minutes; however, capnogram in the anesthesia machine was used for end-tidal carbon dioxide (ETCO2) measurement and recorded every fifteen minutes. Le Roux PD, Winn HR. 2008 Oct. 39(10):2720-6. Δ, mean difference between the lowest point and baselined point at the initial procedure. [Medline]. Sherlock M, O'sullivan E, Agha A.

Data suggested that the optimal cutoff points for lowest blood pressure for prevention of DNID should be systolic blood pressure (SBP) of 95 mmHg (sensitivity of 78.6%; specificity of 53.6%), diastolic blood pressure (DBP) of 50 mmHg (sensitivity of 71.4%; specificity of 67.9%), and mean arterial pressure (MAP) of 61.7 mmHg (sensitivity of 85.7%; specificity of 35.7%). Adams WM, Laitt RD, Jackson A. Thus, ETCO2 may not be a major factor in inducing DNID development. The mean difference between the lowest blood pressure point during operation and baseline blood pressure point and ETCO2 showed a significantly wider range of blood pressure in the DNID group (), whereas a narrower range of ETCO2 was observed in the DNID group () (Table 2).
