ABSTRACT

INTRODUCTION: Detailed information on functional outcome after open abdominal aortic aneurysm (AAA) repair is sparse. Information about functional outcome of open AAA repair is essential to allow comparison of treatment modalities. METHODS: To determine the functional outcome of patients after open repair of AAA, we reviewed 154 consecutive, nonemergency open repairs of infrarenal AAAs between 1990 and 1997 and each patient's medical records. Clinical variables were recorded for each patient, as were multiple outcomes, including ambulatory status, independent living status, current medical condition, and the patient's perception of recovery and satisfaction. Eighty-seven patients or their families were available for current telephone interview to obtain information about objective functional activities, including walking and driving, and subjective functional information, including assessment of complete recovery and willingness to undergo AAA repair again. Chart data were available for all 154 patients. RESULTS: There were 42 women and 112 men. A total of 139 operations were elective, and 15 were urgent. The operative mortality rate was 4%, mean hospital stay was 10.7 +/- 1.3 days, and mean intensive care unit stay was 4.57 +/- 1.17 days. Seventeen (11%) patients required transfer to a skilled nursing facility with a mean stay of 3.66 +/- 2.9 months. All patients were ambulatory preoperatively, whereas at last follow-up (median, 25 months; range, 0.13-108.5 months), 100 (64%) of the patients remained ambulatory, 34 (22%) required assistance, and 12 (14%) were nonambulatory. At current assessment by telephone interview, 33% of patients described a decrease in their functional activity including driving, shopping, and traveling compared with their preoperative status, whereas 67% were unchanged. When asked to assess their own degree of recovery, 64% of patients stated that they experienced complete recovery with an average time to recovery of 3.9 months, whereas 33% said they had not fully recovered at a mean follow-up of 34 months. Sixteen (18%) patients said they would not undergo AAA repair again knowing the recovery process, even though they appeared to fully understand the implication of AAA rupture. CONCLUSION: Patients undergoing open AAA repair generally experienced significant freedom from surgical complications. However, substantial functional impairment was present. It is unclear whether the functional disability resulted from the AAA surgery or from aging and comorbidities unrelated to surgery.

ABSTRACT

PURPOSE: Interest in alternative methods, such as autogenous vein grafts and aortic allografts, for the management of infrarenal aortic infection (IRAI) has been stimulated by the historically disappointing results with conventional surgical management. Recently, there have been dramatic improvements in the results of axillofemoral bypass grafting (AXFB) followed by excision of the IRAI that have gone relatively unrecognized. The purpose of this report is the presentation of modern-day results in the treatment of IRAI with conventional surgical methods. METHODS: From January 1, 1983, through June 30, 1998, patients with IRAI underwent treatment with AXFB and complete excision of the IRAI. The patients were followed for survival, limb salvage, and AXFB graft patency. The results were tabulated with life-table methods. RESULTS: During the 15-year study period, 60 patients (51 men, nine women; mean age, 68 years) underwent treatment for IRAI (50 graft infections, including 16 graft-enteric fistulae, and 10 primary aortic infections). The mean follow-up period was 41 months. The perioperative mortality rate was 13% (12% for graft infection, and 20% for primary infection). The overall 2-year and 5-year survival rates were 67% and 47%, respectively. The limb salvage rates at 2 and 5 years were 93% and 82%, respectively. The 5-year primary AXFB graft patency rate was 73%. CONCLUSION: These results show an improvement with the conventional management of IRAI equal or superior to those results reported with alternative methods, including femoral vein grafts or aortic allografts. These results should be regarded as the modern standard with which alternative therapies can be compared.

ABSTRACT

BACKGROUND: We report results of infected aortic aneurysms treated by a single group over 20 years. METHODS: Retrospective review. RESULTS: Seventeen patients were treated, 10 with infrarenal and 7 suprarenal infections. All had abdominal/back pain, 88% were febrile, 71% had leukocytosis, and 24% were hemodynamically unstable. The most common responsible organism was Staphylococcus aureus (29%) followed by Salmonella organisms (24%). All suprarenal infections were gram-positive organisms. Infrarenal infections were treated with preliminary axillofemoral bypass followed by aortic resection. Suprarenal infections were treated with either in situ prosthetic graft or patch repairs. Operative survival was 90% for infrarenal and 57% for suprarenal infections. Operative deaths occurred in the setting of overwhelming sepsis and/or severe preoperative hemodynamic instability. There was no limb loss, renal failure, or intestinal ischemia. Late deaths occurred in 4 patients at 1.3 to 6.3 years postoperatively and were unrelated to their aortic repairs. Nine patients remain alive with a median follow-up of 2 years. There have been no late aortic or graft infections. CONCLUSIONS: In the absence of hemodynamic instability and uncontrolled sepsis, infected aortic aneurysms can be successfully repaired with durable results.

ABSTRACT

PURPOSE: The outcome of infrainguinal bypass surgery for limb salvage has traditionally been assessed by graft patency rates, limb salvage rates, and patient survival rates. Recently, functional outcome of limb salvage surgery has been assessed by patient ambulatory status and independent living status. These assessments fail to consider the adverse long-term patient effects of delayed wound healing, episodes of recurrent ischemia, and need for repeat operations. An ideal result of infrainguinal bypass surgery for limb salvage includes an uncomplicated operation, elimination of ischemia, prompt wound healing, and rapid return to premorbid functional status without recurrence or repeat surgery. The present study was performed to determine how often this ideal result is actually achieved. METHODS: The records of 112 consecutive patients who underwent initial infrainguinal bypass surgery for limb salvage 5 to 7 years before the study were reviewed for operative complications, graft patency, limb salvage, survival, patient functional status, time to achieve wound healing, need for repeat operations, and recurrence of ischemia. RESULTS: The mean patient age was 66 years. The mean postoperative follow-up was 42 months (range, 0 to 100.1 months). After operation 99 patients (88%) lived independently at home and 103 (92%) were ambulatory. There were seven perioperative deaths (6.3%), and wound complications occurred in 27 patients (24%). By life table, the assisted primary graft patency and limb salvage rates of the index extremity 5 years after operation were 77% and 87%, respectively, and the patient survival rate was 49%. At last follow-up or death, 73% of the patients (72 of 99) who lived independently at home before the operation were still living independently at home, and 70% (72 of 103) of those who were ambulatory before the operation remained ambulatory. Wound (operative and ischemic) healing required a mean of 4.2 months (range, 0.4 to 48 months), and 25 patients (22%) had not achieved complete wound healing at the time of last follow-up or death. Repeat operations to maintain graft patency, treat wound complications, or treat recurrent or contralateral ischemia were required in 61 patients (54%; mean, 1.6 reoperations/patient), and 26 patients (23.2%) ultimately required major limb amputation of the index or contralateral extremity. Only 16 of 112 patients (14.3%) achieved the ideal surgical result of an uncomplicated operation with long-term symptom relief, maintenance of functional status, and no recurrence or repeat operations. CONCLUSIONS: Most patients who undergo infrainguinal bypass surgery for limb salvage require ongoing treatment and have persistent or recurrent symptoms until their death. A significant minority have major tissue loss despite successful initial surgery. Clinically important palliation is frequently achieved by bypass surgery, but ideal results are distinctly infrequent.

ABSTRACT

Duplex ultrasonography accurately identifies high-grade stenoses in the SMA. Analysis of velocity data reveals few false positives and virtually no false negatives in the determination of high-grade SMA stenosis by duplex scanning. We therefore utilize duplex scanning to perform early screening studies of patients with symptoms suggestive of chronic visceral ischemia. If the duplex findings are negative, we recommend evaluating for other sources of abdominal pain. If the findings are positive, prompt angiography is indicated. It is important to remember that although duplex scanning can identify mesenteric artery stenosis, it cannot diagnose intestinal ischemia. By establishing duplex scanning as a useful and accessible noninvasive screening tool, it is hoped that the time between onset of visceral ischemic symptoms and diagnosis of chronic visceral ischemia will be shortened significantly, potentially reducing the morbidity and mortality of the disease.
