These figures form the natural history against which the decision to treat and when to treat should be balanced. The risk of rebleeding is greater in patients in higher SAH grades, the gain of - surgical - treatment is inversely related to grade.
As a result, many patients died while waiting. Today, at least in the larger centres, the attitude is to operate early on patients in grade I - III, and to postpone surgery in the others. The more difficult cases posterior circulation, giant aneuysms are postponed as well.
In poor grade patients with define aneurysm hydrocephalus, ventricular drainage may bring the patient one grade up, making him fit for surgery. Some centres favour surgery on even poor grade patients, saving some of them without enlarging the poor outcome vegetative state category. Other centres still continue to postpone surgery in every SAH patient. So there are still controversies on these issues, as there are many arguments in favour and against early surgery!
It is obvious that a lot more can be said about the decision process in this stage: co-morbidity, age, resulting life expectancy, experience of the surgeon s ' own track records! In recent years, the alternative to surgical repair - endovascular treatment - has come into the armamentarium, changing the whole field of this discussion see next.
It should be recognised that there is no Class I data define aneurysm support one of the decision options to date for a concise survey see Greenberg 8.
Clip or Coil The boom in endovascular treatment - presumably with Guglielmi define aneurysm - has changed the scope in timing and decision. Details will be presented elsewhere in this course. For decision-making it is important to know results so far, and to realize that a clip - provided that it is properly placed - occludes definitively, while for coiling there is not that same proof.

On the other hand, coiling results are very promising, improving over recent years, with acceptable complication rates and apparently no negative effect on the frequency of hydrocephalus or vasospasm. Studies are underway to show long - term results and outcome.

Experience varies per centre; a state of the art for indications has not been established yet. In most centres today the coiling of posterior aneurysms - until now very often postponed for the first 12 days after SAH - has become the upfront treatment within 72 hours after the bleed.
Its role define aneurysm other indications will become established in the near future 25.

Post-Treatment Care Once the aneurysm has been taken care of, the patient will encounter many serious problems and threats: delayed ischaemic deficits DID from vasospasm, hyponatremia, hydro- cephalus, and more. The use of nimodipine has been adopted world-wide. Other treatment and care modalities HHH, for example are largely based on the belief and not on proof of define aneurysm effectiveness.
Day to day monitoring is the key issue define aneurysm course. Despite many drug trials, no specific medication has proven to be significantly effective in preventing DID except nimodipine, which is not always enough, though. Decisions have to be made on guidelines and experience rather than on evident data see the major textbooks. There is place for new prospective studies in this field!

Coiling might be an option here as well. Once again, one should be define aneurysm of the natural history, which for the non-bleeding aneurysms is different from the one that has bled see next paragraphbefore planning a second operation to reach all aneurysms.
Iatrogenic pseudoaneurysms – Ultrasonographic evaluation
Unruptured Aneurysms and Screening All neurosurgeons involved in aneurysm surgery are aware of the often contradictory data concerning the risk of rupture in unruptured aneurysms, define aneurysm symptomatic or incidentally found 13 The ISUIA study has given a lot of data, showing much lower rupture risks than thought before, and higher surgical complication rates than neurosurgeons want to think of 21!
At this stage, it is too early to make definite statements on risks, the results of the continuing ISUIA study have to define aneurysm awaited, and one should not take part in self-fulfilling prophecies by completely changing the indications and decision routine already.
It is evident that low rupture risks for non-bleeding aneurysms have enormous bea din varicoza for the usefulness of screening in populations, and even among relatives of SAH patients.
This will be dealt with elsewhere. This will certainly result in a good or the best!

By the use of decision analysis methods, such decision-making can be formalized, leading to comprehensible decision define aneurysm 9. By filling in known probability figures, like natural history aspects annual risk of rupture; mortality and morbidity of rupture and treatment aspects surgical morbidity, mortalitypatient's co-morbidity, age and life expectancy, and correcting for quality aspects including the fear of the patient define aneurysm knows define aneurysm he has an aneurysm!
Conclusion For a scientific basis to the best treatment of patients with saccular aneurysms, and especially those with aneurysmal SAH, a sound and reliable grading system should be applied, as well as logical management steps based on data of results and final outcome for the various treatment options.
Unfortunately, not all facts and figures available have that level of evidence.
Recognition of the process of decision-making, enlightening define aneurysm weak and strong parts of it, define aneurysm help to improve decision-making itself, and thereby enhance the overall management of patients with saccular aneurysms.
