A 78-year-old woman is described who presented with a diaphragmatic hernia through the foramen of Morgagni. A definitive
diagnosis was confirmed by a sagittal view on magnetic resonance imaging prior to surgery. The hernia was repaired laparoscopically
under an abdominal wall lifting technique without pneumoperitoneum, and her symptoms completely resolved postoperatively with
no evidence of recurrence. The laparoscopic repair was considered a suitable and safe procedure for the treatment of a Morgagni
hernia.

Background. The “elephant trunk” technique, using a free-floating vascular prosthesis, was originally described to facilitate a subsequent operation on the downstream aorta. We developed an additional refinement of this technique, called the “bidirectional elephant trunk.” This option may represent an interesting tool in more complex aortic operations, especially when the descending aorta has to be replaced first in patients with concomitant pathology of the ascending aorta or of the aortic arch.
Methods. The initial operation is performed through a left thoracotomy. The proximal elephant trunk is created by invaginating the future aortic arch graft into the descending aortic graft. The proximal anastomosis between the doubled graft and the proximal descending aorta is performed first. During construction of the distal anastomosis, a distal elephant trunk may be inserted likewise. If the aortic arch and ascending aorta have to be replaced later, this second step is performed through a median sternotomy. The free-floating arch graft is pulled out of the proximal descending aorta with a nerve hook, unfolded, and used for total arch replacement.
Results. This technique was used successfully in 3 patients without mortality. No major complications were observed excepted persistent hoarseness in a patient with preoperative paresis of the recurrent nerve. No perfusion problems due to the unfolding of the free-floating graft occurred during the second operation.
Conclusions. The bidirectional elephant trunk technique is an interesting option that may be suitable for patients presenting with a complex pathology of the whole thoracic aorta when the descending segment has to be replaced first. 相似文献
A 66-year-old man presented with bilateral subclavian steal syndrome (SSS) due to proximal subclavian artery occlusions. He was treated by percutaneous transluminal balloon angioplasty (PTA) and stent implantation in the left subclavian artery and by PTA alone in the right subclavian artery. We could demonstrate that interventional treatment of symptomatic bilateral SSS is possible. If PTA alone is insufficient, stent implantation should be considered. 相似文献
A 10-year-old girl having bilateral subclavian steal associated with severe coarctation of the thoracic aorta and an aberrant
right subclavian artery was found, on admission, to have no difference between upper and lower extremity blood pressure, but
echocardiography revealed severe thoracic aorta coarctation and systolic blood pressure in the carotid arteries exceeding
200 mmHg estimated by Doppler ultrasonography. Magnetic resonance imaging and angiography demonstrated bilateral subclavian
steal without esophageal compression. We reconstructed the aortic arch using the left subclavian artery and a reversed Blalock-Park
procedure, then repaired the coarctation with a 14 mm woven double velor vascular graft. The girl was symptom-free following
uncomplicated recovery from surgery. Doppler ultrasonography 2 weeks after surgery showed the pressure gradient across the
aortic arch had decreased from 180 mmHg to 60 mmHg. This residual gradient at the anastomosis between the ascending aorta
and left subclavian artery may improve as native vessels grow. 相似文献
