Carotid artery surgery (CAS) performed under cervical plexus block is frequently associated with significant intra- and postoperative pain. To evaluate whether preoperative administration of ketorolac may improve analgesia in this type of surgery, 80 patients scheduled for CAS under cervical plexus block were randomly allocated to receive intravenously either 30 mg of ketorolac or placebo 30 minutes before surgery. Verbal rating scale pain scores during surgery and 3 and 6 hours after surgery, the number of patients requiring additional analgesia, and the total analgesic consumption both during and within 6 hours after surgery were significantly lower, whereas the time to first postoperative analgesia was significantly shorter in the ketorolac group than in the control group. The results of this prospective, randomized, double-blind study show that a single 30 mg dose of ketorolac administered intravenously 30 minutes before surgery reduces intraoperative pain and preempts postoperative pain in patients undergoing CAS under carotid plexus block. © BC Decker Inc.

In this study we aimed to define relevant prognostic predictors for the outcome of surgical treatment of ruptured abdominal aortic aneurysms. The study included 406 consecutive patients treated between January 1991 and December 2003. There were 337 (83%) male and 69 (17%) female patients aged 67 ± 7.5 years. Fourteen (3.5%) patients had aortocaval fistula whereas 4 (0.98%) had primary aortorenteric fistula caused by aneurysm rupture into the inferior vena cava or duodenum. Reconstruction included interposition of a tube graft (215-53%), aortobiiliac bypass (134-33%), and aortobifemoral bypass (58-14.3%). Findings on admission that significantly correlated with both intraoperative (13.5%) and total operative mortality (48.3%) were systolic blood pressure <95 mmHg, low diuresis, unconsciousness, cardiac arrest, leukocytes >14 × 109/L, hematocrit <0.29%, hemoglobin <100 g/L, urea> 11 mmol/L, and creatinine >180 μmol/L. Intraoperative determinants of increased mortality were aortic cross-clamping time >47 min, duration of surgery >200 min, intraoperative blood loss >3500 mL, diuresis <400 mL, arterial systolic pressure <97.5 mmHg, and the need for aortobifemoral bypass. Respiratory complications and multisystem organ failure were significantly associated with lethal outcome in the postoperative period. Surgical treatment of ruptured abdominal aortic aneurysm was life-saving in 51.7% of patients. Variables significantly associated with mortality were unconsciousness, low systolic blood pressure, cardiac arrest, low diuresis, high urea and creatinine levels, signs of blood loss, and the need for aortobifemoral reconstruction. Short aortic cross-clamping and the total operation time, low intraoperative blood loss, and well-controlled diuresis and arterial pressure during surgery have improved survival. Therapeutic efforts should concentrate on intraoperative factors that are possible to correct, leading to better survival of these patients. © Annals of Vascular Surgery Inc.

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. © 2011 Royal Society of Medicine Press.
