Delayed paraplegia in transition countries: are we missing something?

Some technical considerations of open thoracoabdominal aortic aneurysm repair in a transition country

A variety of operative approaches and protective adjuncts have been used in thoracoabdominal aneurysm (TAA) repair to minimize the major complications of perioperative death and spinal cord ischemia. There is no consensus with respect to the optimal approach. We present 118 surgically treated patients over a 10-year period. The present study reviews our experience as a transition country (Serbia) in the treatment and problems we have encountered during open operative treatment of TAAs. Between 1999 and 2009, the authors reviewed 118 consecutive patients who underwent thoracoabdominal aortic resection using a variety of spinal cord protection. Clinical data collected prospectively were analyzed retrospectively. The purpose of the current study was to review the results of a large series of TAA repairs and to present some technical considerations and complications of open TAA repair. There were seven operative deaths (5.9%): two in the setting of ruptured TAAs, three myocardial infarctions and two due to hemorrhage. All 30 (25.4%) postoperative deaths occurred during the initial hospitalization. Postoperative complications included paraplegia in 11 patients (9.3%); renal failure in eight patients (6.8%), with four patients (3.4%) requiring hemodialysis; pulmonary complications in 75 patients (63.5%); bleeding requiring reoperation in two patients (1.7%) and coagulopathic hemorrhage in five patients (4.2%); cardiac complications in six patients (5.1%); stroke in five patients (4.2%); wound dehiscence in six patients (5.1%); and subdural hemorrhage in one patient (0.87%). Open TAA repair intrinsically has substantial complications, of which spinal cord ischemia and renal failure are the most devastating, despite major progress in our understanding of the pathophysiology and operative strategy. Our current review of data clearly proves that the surgical repair of TAAs remains a challenge even in the 21st century, especially in a country in transition.
