With the easier and earlier recognition of complex regional pain syndrome (CRPS), a reappraisal of its therapy, particularly the role and timing of sympathectomy, is warranted. ⋯ Early recognition of CRPS and prompt recourse to surgical sympathectomy is a useful option in the management of CRPS.

Comparative Study
Is carotid angioplasty and stenting more cost effective than carotid endarterectomy?
Carotid angioplasty and stenting (CAS) has been advocated as a minimally invasive and inexpensive alternative to carotid endarterectomy (CEA). However, a precise comparative analysis of the immediate and long-term costs associated with these two procedures has not been performed. To accomplish this, a Markov decision analysis model was created to evaluate the relative cost effectiveness of these two interventions. ⋯ CEA is cost saving compared with CAS. This is related to the higher rate of stroke with CAS and the high cost of stents and protection devices. To be economically competitive, the mortality and major stroke rates of CAS must be at least equivalent if not less than those of CEA.

Case Reports
Aortoduodenal fistula and associated rupture of abdominal aortic aneurysm after endoluminal stent graft repair.
The main complications of endovascular repair of abdominal aortic aneurysms are vascular leaks and rupture, although infection and aortoduodenal fistulas have also been reported rarely. We report a case of aortoduodenal fistula with separate retroperitoneal rupture of an abdominal aortic aneurysm after endovascular stent graft repair. ⋯ The patient underwent open repair and did well. To our knowledge, this is the first case report of aortoduodenal fistula and associated retroperitoneal rupture of the aneurysm after endovascular stent graft repair of an abdominal aortic aneurysm.

Compensatory sweating is the most common and troublesome complication of thoracodorsal sympathectomy. Whether the magnitude of compensatory sweating is related to the extent of sympathectomy is unclear. We investigated the association between the extent of sympathectomy and the occurrence and severity of compensatory sweating after endoscopic transthoracic sympathectomy for upper limb hyperhidrosis. ⋯ Compensatory sweating was the most common long-term complication of thoracodorsal sympathectomy for primary hyperhidrosis. Its incidence and severity were not associated with the extent of sympathectomy.

The most common site of venous reflux is the long saphenous vein (LSV). The preferred treatment for reflux in the LSV is surgical stripping of the LSV. However, the complications of surgical stripping are well documented and undesirable. The constant search for treatment options with less morbidity, which are also cosmetically more acceptable, has resulted in the endovenous treatment for primary varicose veins, developed by VNUS Medical Technologies, Inc (Sunnyvale, Calif). We hereby present our first treatment experiences and propose refinements to the procedure. ⋯ The endovenous catheter should not be used more than 5 to 10 cm below the knee to prevent saphenous nerve damage. Performance of the procedure with bloodlessness is preferable. A result of 88% of successfully treated LSV segments indicates a promising alternative for surgical stripping of the LSV.
