Proximal opening-wedge osteotomy of the first metatarsal for moderate and severe hallux valgus using low profile plates

BackgroundTo present the results of the treatment of hallux valgus with the proximal metatarsal opening wedge (PMOW) osteotomy using two different screw and plate systems.MethodsForty-one patients with moderate and severe hallux valgus were treated with the PMOW osteotomy between 2005 and 2009. The fixation was obtained by the Darco^® BOW or by the Arthrex^® LPS plate. Biplanar chevron and/or Akin osteotomy were associated according to the magnitude of distal angles. Each patient was evaluated with weight-bearing radiographs and AOFAS score.ResultsThe HV, IM, DMA and IP angles improved by a mean of 14°, 8°, 11°, 7° respectively. The sesamoid position improved in 79% of the feet. AOFAS score improved from a mean of 50 to 82.ConclusionThe PMOW osteotomy is effective to correct high-level hallux valgus deformities. Both systems guarantee the stability and correction of the osteotomy site. The combination with distal procedures is advisable to correct distal angles.     

Survival in Thoracic or Thoracoabdominal Aortic Aneurysm: Comparison between patients with or without surgical treatment

The surgical mortality among 22 patients treated for thoracic or thoracoabdominal aneurysm was compared with the mortality in 47 patients managed without surgery. Surgical mortality (<30 days) was low (1/13) in ascending aortic aneurysm, but higher (3/8) in aneurysm of the descending or thoracoabdominal aorta (including both acute and elective operations). Of the 20 non-surgically managed patients in the latter group, 15 died after a mean of 1.1 year. The only patient operated on for aortic arch aneurysm died of cerebral ischaemia 2 days postoperatively. Most of the 19 non-operated patients with aneurysm of the arch or total aorta (mean age 76 years) were never considered for surgical treatment. The analysis supports aggressive management of patients with aneurysm of the ascending, descending or thoracoabdominal aorta. Many of our patients with aneurysm of the arch or involving most of the aorta were old and had other, concomitant diseases, and in such cases an aggressive treatment strategy does not seem justified.     

Surgical closure of patent foramen ovale in patients with suspected paradoxical embolism: long‐term results

Objective—It is thought that a patent foramen ovale (PFO) is the crucial mechanism in patients with suspected paradoxical embolism and cryptogenic stroke. It has been hypothesized that closure of the PFO would prevent further cerebrovascular incidents. We describe our early and late experience with surgical closure of PFO in patients with paradoxical embolism.

Patients and methods—Between May 1994 and December 2001, 33 patients (26 men, 7 women; mean age, 55.2?±?8.7 years; range, 37–74 years) underwent surgical closure of a PFO at our institution. All patients had preoperatively suffered from a stroke and/or a transient ischemic attack, after which echocardiography showed a PFO. Mean follow‐up at 99?±?30 months (range, 10–111 months) was 100% complete.

Results—All patients survived the operative procedure. Early complications occurred in four patients (12%). Actuarial survival at 1, 5 and 8 years was 97?±?3%, 97?±?5% and 94?±?8%, respectively. At long‐term follow‐up all but two patients were alive. The deaths of these two patients were related to malignancy and ischemic heart disease, respectively. Two patients (6%) had suffered a residual cerebrovascular event after successful surgery.

Conclusion—Surgical closure of PFO in patients with paradoxical embolism can safely be performed with a low risk of early mortality. Residual thromboembolic events were rare and in those few it occurred it did so with the interatrial septum being closed, indicating that in those patients the PFO was not the mechanism of the thromboembolic event in the first place.
