(1) Background: Midline meningiomas such as olfactory groove (OGMs), planum sphenoidale (PSMs), or tuberculum sellae meningiomas (TSMs) are challenging, and determining the appropriate approach is important. We propose a decision algorithm for choosing suitable transcranial approaches. (2) Methods: A retrospective chart review between 06/2007 and 01/2020. Clinical outcomes, radiographic findings, and postoperative complication rates were analyzed with respect to operative approaches. (3) Results: We included 88 patients in the analysis. Of these, 18.2% (16/88) underwent an interhemispheric approach, 72.7% (64/88) underwent a pterional/frontolateral/supraorbital approach, 2.3% (2/88) underwent a unilateral subfrontal approach, and 6.8% (6/88) underwent a bifrontal approach. All OGMs underwent median approaches, along with one PSM. All of the other PSMs and TSMs were resected via lateral approaches. The preoperative tumor volume was Æ20.2 ± 27.1 cm3. Median approaches had significantly higher tumor volume but also higher rates of Simpson I resection (75.0% vs. 34.4%). An improvement of visual deficits was observed in 34.1% (30/88). The adverse event rate was 17.0%. Median follow-up was 15.5 months (range 0–112 months). (4) Conclusions: Median approaches provides satisfying results for OGMs, lateral approaches enable sufficient exposure of the visual apparatus for PSMs and TSMs. In proposing a simple decision-making algorithm, the authors found that satisfactory outcomes can be achieved for midline meningiomas.
Today, mitral valve replacement is performed under cardioplegic arrest with cross-clamping of the ascending aorta. In the case reported here, mitral valve replacement was performed with an on-pump beating heart technique without cross-clamping the aorta because of diffuse adhesion around the tube graft. A 36-year-old man had undergone a Bentall operation (aortic root replacement+coronary reimplantation) via median sternotomy because of type I aortic dissection 4 years previously in our cardiac center. He was admitted to the hospital complaining of palpitation and dyspnea on mild exertion. Transthoracic echocardiography study revealed third-degree mitral insufficiency. Mitral valve replacement was carried out through re-median sternotomy with an on-pump beating heart technique without crossclamping the aorta. On-pump beating heart mitral valve replacement without a cross-clamp offers a safe approach when excessive dissection is required to place a crossclamp on the ascending aorta.
Weaning from cardiopulmonary bypass is the most important stage during mitral valve surgery, especially in patients with severe pulmonary hypertension. We report two patients with severe pulmonary hypertension who were operated on because of valvular heart disease. To reduce the pulmonary artery pressure, levosimendan was used because of its vasodilatory and cytoprotective effects. All patients tolerated the operation and levosimendan administration. Their postoperative course was uneventful. Levosimendan can be used to treat pulmonary hypertension during operations for heart valve disease. Patients clearly benefit from the vasodilator action of the drug for reducing pulmonary artery pressure.
Brachial artery cannulation is technically simple and less time consuming, thus suitable even for emergency cases. With an acceptable risk of local complications, we recommend routine use of upper brachial cannulation for antegrade cerebral perfusion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
