To determine how arterial spin labeling (ASL) measured perfusion relates to baseline metabolism, we compared resting state cerebral perfusion using pseudo-continuous ASL and cerebral glucose metabolism using (18)F-FDG PET in 20 normal volunteers. Greater regional metabolism relative to perfusion was observed in the putamen, orbitofrontal and temporal lobes, whereas perfusion was relatively higher in the hippocampus and insula. In a region of interest analysis limited to gray matter, the overall mean correlation between perfusion and metabolism across voxels was r=0.43 with considerable regional variability. Cross-voxel correlations between relative perfusion and metabolism in mean ASL and PET images of all 20 subjects were the highest in the striatum (caudate: r=0.78; putamen: r=0.81), and the lowest in medial temporal structures (amygdala: r=0.087; hippocampus: r=-0.26). Correlations between mean relative perfusion and metabolism across 20 subjects were the highest in the striatum (caudate: r=0.76; putamen: r=0.58), temporal lobe (r=0.59), and frontal lobe (r=0.52), but very poor in all other structures (r

Background: After extracorporeal membrane oxygenation (ECMO), acute compartment syndrome (ACS) can develop because of limb ischemia or reperfusion. The standard treatment for ACS is emergency fasciotomy. We introduced an interrupted incision technique instead of a long double‐incision to reduce blood loss and subsequent hypovolemia in ECMO patients. Case presentation: Two patients were treated venoarterial ECMO with heparinization by inserting cannulas into their right femoral vessels: Case #1 after emergency pulmonary thrombectomy for massive pulmonary thrombi and Case #2 after percutaneous coronary intervention for ST‐elevation myocardial infarction with ventricular fibrillation. Some of the '5 P' signs of ACS were detected on their right legs. We treated them with the interrupted incision fasciotomy: four or five skin incisions of 2–3 cm each on lateral side; one 6–7 cm proximal skin incision with one or two separate short distal skin incisions of 1–1.5 cm each on the posteromedial side. The subcutaneous layer was also incised through these interrupted incisions; interrupted multiple "soft tissue tunnels" can be formed above muscle layer between the incisions. Once the fascia was exposed, the connected fasciotomy was performed with the knife blade facing subcutaneous layer, rather than muscle. The two patients' foot pulse, skin color, and muscle tone were immediately restored, and delayed primary wound closures were possible. Both patients were satisfied with their limb salvage and could walk with a little help using an orthosis or a cane. Conclusions: We recommend the interrupted incision fasciotomy as an attractive and effective technique for ACS, particularly after ECMO. [ABSTRACT FROM AUTHOR]

Compared to other lateral soft tissue release methods during hallux valgus surgery, the medial transarticular approach has the advantages of being reproducible, safe, and simple. However, a few reports have described the disadvantages of medial transarticular lateral soft tissue release, including only inadequate lateral soft tissue release. Herein, we report a case of intermetatarsal neuroma in the first web space after hallux valgus correction using distal chevron metatarsal osteotomy and medial transarticular lateral soft tissue release. This case report aimed to highlight the possibility of nerve damage due to medial transarticular lateral soft tissue release during hallux valgus correction surgery.
