Can you have multiple aneurysms




















On the other hand, treatment of additional unruptured aneurysms in patients with MIAs in the acute phase of the SAH is discussed controversially due to the risk of additional complications, and is therefore usually performed secondarily [ 12 ].

Depending on the size and location of the remaining unruptured aneurysms and the clinical condition of the patients, secondary treatment is applied in interdisciplinary consensus. Orning et al. However, in the same study there was a high inaccuracy in cases of nondefinite hemorrhage pattern.

Uncertainty arises in cases with a diffuse and symmetric hemorrhage pattern, or a localized pattern, but with multiple aneurysms in that particular area are present in the same patient.

Because this prediction score was developed for the uncommon but usually troublesome cases, where the hemorrhage pattern does not provide any further clues for the identification of the bleeding source, CT findings were deliberately not included in the score.

Given the fact that in all cases the CT findings would not provide further information, the value of this parameter would be constant for each aneurysm without any influence on the score.

According to previous studies, size and location are postulated as independent risk factors for aneurysm rupture [ 13 , 14 , 15 , 16 , 17 , 18 ]. According to the ISUIA trial, aneurysms located at the posterior circulation including the PcomA, have a higher possibility of rupture [ 15 ]. However, Juvela et al. In patients with MIAs, aneurysms located at the AcomA had the highest probability to rupture according to Nehls et al. According to the findings of the present study, the site with the highest probability of a ruptured aneurysm in patients harboring MIAs was the AA including the AcomA.

Furthermore, aneurysm size was also identified to be a risk factor for aneurysm rupture. Backes et al. Therefore, the use of aneurysm size or aneurysm location alone seems not to predict the ruptured aneurysm adequately. Irregular aneurysm shape is considered to be associated with aneurysm enlargement which is a surrogate parameter for aneurysm rupture [ 20 , 21 ].

Maslehaty et al. In the present study, irregular shaped aneurysms were also found to rupture more likely compared to regularly shaped aneurysms. Aim of the development of the scoring system was to create a simple tool, to identify the ruptured aneurysm in patients with MIAs and unclear bleeding pattern in cases of SAH.

Therefore, the described prediction score can easily be assessed and used in the clinical setting. According to our findings and experience using the prediction score, for example in the illustrative case, it can provide additional information and improve the treatment decision.

The score is developed to be used in cases with diffuse SAH, without distinct bleeding pattern pointing out the bleeding source. In all these challenging cases, for which the prediction score was initially developed, the bleeding source was identified correctly.

In contrast, the neurovascular team predicted the true bleeding source in three of the five patients correctly. Given the uncertainty in some challenging cases, treatment of all possible bleedings sources was performed. The true value of the prediction score might be in troublesome cases, where treatment of multiple aneurysms might not be easily feasible due to aneurysm or patient specific characteristics. The prediction model can provide additional information for the decision-making process.

The score was derived from a retrospective dataset of the authors institution and was then prospectively validated at the same center. Furthermore, the prospective validated score was conducted with a relatively small number of patients, since patients harboring MIAs with SAH represent just a small fraction of all SAH patients and the troublesome cases with non-definite bleeding pattern are infrequent. The prediction score was additionally validated with endovascularly treated aneurysms, in order to gain a greater number of patients.

In all patients treated endovascularly, the bleeding pattern pointed unambiguously the ruptured aneurysm. Given the fact that the challenging cases needed for prospective validation are overall rare, multicenter independent data is necessary. This simple prediction score might provide support for neurovascular teams for treatment decision in SAH patients harboring multiple intracranial aneurysms and no definite hemorrhage pattern in order to identify the ruptured aneurysm.

However, larger cohorts for prospective evaluation are warranted.

Other symptoms that may occur with aneurysms in the brain, and their causes may include, but are not limited to, the following:. Johns Hopkins estimates that two percent of people have one or more brain aneurysms. Most aneurysms declare themselves by bleeding in adults between the ages of 45 to 65 years.

Children, however, can also have brain aneurysms. In fact, two percent to three percent of patients with aneurysms that we treat at Johns Hopkins are children. We attempt whenever possible to identify and address aneurysms before they bleed. The type of diagnostic testing performed depends on the location of the aneurysm.

In addition to a complete medical history and physical examination, diagnostic procedures for an aneurysm may include one or more of the following tests:.

At Johns Hopkins, we treat brain aneurysms using one or more methods, depending on the type of aneurysm and the individual patient's situation. Treatments may include:. Specific treatment will be determined by your physician. Twenty percent of aneurysm patients have multiple aneurysms, often on opposite sides of the brain.

Traditionally, surgeons perform two separate operations, one for each side of the brain. Rafael Tamargo , director of the Johns Hopkins Cerebrovascular Center, is among a handful of surgeons worldwide to use a one-surgery, contralateral approach. Read aneurysm expert Judy Huang, M.

Johns Hopkins is one of the few hospitals in the country that treats more than aneurysm cases a year Dr. Tamargo and Dr. Huang treat an average of about aneurysm cases a year. We have published our aneurysm treatment results, which rank among the best in the world. To request an appointment or refer a patient, please call: Neurology: Neurosurgery: There was no evidence that a previously intact aneurysm had ruptured in SAH patients treated with bed rest, indicating that late hemorrhage was due to rerupture from the original aneurysm.

Patients who were hypertensive and who had a large aneurysm had an increased risk of late rehemorrhage. A linear discriminant analysis was developed to predict late rebleeding.

The fate of intact aneurysms was evaluated by following patients with multiple aneurysms treated by craniotomy directed only at the ruptured aneurysm. Of the 50 craniotomy patients, 38 were alive after 6 months.
