Rupture of a Dacron arterial prosthesis is a most unusual complication, although it has been reported previously. Three further such cases are reported with a brief review of the relevant literature.
A retrospective analysis of 75 patients with 103 atherosclerotic popliteal aneurysms, seen at Princess Alexandra Hospital, Brisbane, was undertaken to assess the results of management and the most appropriate approach to the contralateral popliteal aneurysm. These patients were seen between January 1968 and December 1985. There were no females, the mean age was 66.3 years and 36% of the patients had bilateral popliteal aneurysms. There was a high incidence of other associated aneurysms, abdominal aortic (21), femoral (12) and isolated iliac (3). Thrombosis in a popliteal aneurysm was the most common reason for presentation initially (48%), followed by detection of a lump in the popliteal fossa (22.6%), embolic phenomena (10.6%) and ruptured popliteal aneurysm (four cases). The most common presentation for contralateral aneurysms was detection of a lump in the popliteal fossa. Management of the contralateral popliteal aneurysm was classified as early, elective repair (n = 14) and no surgery or surgery delayed until the development of symptoms (n = 14). Outcome was classified as successful, retained and fully functional limb at follow-up; or failure, amputation or debilitating ischaemia. There was one failure among those undergoing early elective repair and seven failures among those undergoing no or delayed surgery (P = 0.033, Fisher's Exact Test). There were 79 reconstructions. Bypass and ligation (n = 54) resulted in two amputations and two long-term occlusions, interposition augmented vein graft (n = 15) in two amputations and no long-term occlusions and interposition Dacron grafts (n = 10) with no amputations and three long-term occlusions.(ABSTRACT TRUNCATED AT 250 WORDS)
A review of arterial embolism to upper and lower limbs from 1961 to 1985. During this period 253 patients were treated for 269 episodes of embolus at the Princess Alexandra Hospital. The period was divided into 5 year intervals and analysis showed significantly increasing age for the population over this period. Similarly a decreasing mortality rate was noted during this period although limb salvage did not change after the initial 5 year period. There was a rising incidence of atherosclerotic ischaemic heart disease and a decreasing incidence of rheumatic heart disease. The overall mortality rate was 15.6% while the overall amputation rate was 8.2%. Factors significantly related to survival were acute myocardial infarction and level of occlusion. Factors significantly relating to morbidity were pre-operative heparin administration and performance of completion angiography. The performance of completion angiography was shown to improve the result from embolectomy without having adverse influence on the mortality rate. The results of this review indicate that preoperative heparinization, the performance of completion angiography, and the flexibility to explore multiple levels of the limb circulation, are essential factors in the management of peripheral arterial embolism.
Involvement of the carotid artery by malignant disease may present the surgeon with a dilemma. An aggressive approach to the problem may improve results in some cases that have not developed distant metastases. Adequate assessment in the planning of a curative surgical procedure is necessary and some of the problems in dealing with involvement of the artery are discussed.
The successful management of 2 patients is reported, each involving the closure of a fistula into the inferior vena cava as a sequel to the rupture of an atherosclerotic aortic aneurysm. It is an uncommon complication which should be suspected in the presence of an aortic aneurysm with a loud machinery bruit. Associated peripheral cyanosis and venous pulsation in the accessible proximal veins of the lower extremity and priapism afford strong supporting evidence.
One hundred and sixty-eight ruptured aortic aneurysms presenting at the Princess Alexandra Hospital in an 11-year period have been reviewed. Surgical treatment still carries a high mortality and a very high postoperative morbidity. The survival rate in the Vascular Unit of this hospital has improved during the period studied and in the last five years has risen to 61%. The operative technique is described in detail, and the operative problems and complications are discussed. It is felt that prompt surgical treatment, and accurate assessment of blood loss with adequate replacement during surgery, combined with attention to early postoperative problems, particularly those of a respiratory nature, are the most important factors in survival.
A case of secretory (juvenile) carcinoma of the breast is reported in a 26-year-old multiparous woman who had been taking oral contraceptives for 7 months. The tumour recurred 8 months after local resection and axillary metastases were found at radical mastectomy. No further recurrence has been detected but the follow-up period is only 8 months. It is emphasized that secretory carcinoma of the breast originally described in children occurs also in adults. Early reports stressed the slow rate of growth, often with intervals of many years before recurrence, and the small risk of metastatic spread, many cases being cured by local resection. However, axillary metastases have been found in approximately 15% of the recorded cases. Consequently it is recommended that the initial treatment should be simple mastectomy with at least a low axillary resection.
