Thirty-three patients with one or several late occlusions in 43 limbs of aortofemoral dacron grafts underwent 56 reconstructions because of impending limb loss. Thrombectomy alone with patch closure was less successful. Excision of the femoral anastomosis, resection of the distal part of the occluded prosthetic limb and replacement by a new velours graft tube together with profundaplasty and further downstream reconstruction revealed the best results. The early reocclusion rate was 10%, the late reocclusion rate was 10%. There was no operative mortality and no amputation. Two late deaths occurred, in one case due to grade III infection with sepsis. Another late graft infection was successfully managed by an extraanatomic bypass and excision of the infected limb. The reasons for late occlusions of aortofemoral grafts were found to be incomplete reconstruction of the outflow tract, technical failure at the time of primary reconstruction and progressive atherosclerosis. Hypertonus was common in all cases with progression of the disease. Technical details of the operative management for late occlusion are presented.

Calcification in cutaneous blood vessels is an uncommon finding in biopsies submitted for dermatopathological examination. Of 14 biopsy specimens showing the phenomenon that was studied by us, the greater number was from women who had a combination of severe diabetes, hypertension, and atherosclerosis. Unusual clinical syndromes as the bases for the vascular calcification were hyperthyroidism in three patients and arteritis in two patients. Three patients died as a consequence of massive cutaneous infarction and sepsis, probably stemming from cutaneous vascular calcification. Vascular calcification in biopsy of skin may result from metabolic, inflammatory, or degenerative diseases of blood vessels.

"Mycotic" aneurysm was originally described by Osler in 1885. It occurs in a normal or atherosclerotic artery from septic emboli in patients with infective endocarditis. However, now the term "mycotic" aneurysm is applied to all cases of aneurysms caused by any organisms. From September 1988 to November 1990, four cases of ruptured mycotic aneurysm were diagnosed at our institute. Three were males and one was a female; they were elderly with atherosclerosis of the aorta. The diagnosis was established by computed tomography (CT) scan, bacteriology or operative findings. Two of the patients underwent emergency operation; only one survived. In general, the diagnosis of mycotic aneurysm is based on the classical features of fever, abdominal or chest pain, positive blood culture and a pulsatile mass. Because the clinical manifestations are often variable, a patient may present with chronic sepsis (esp. Salmonella sp) of unknown origin with deterioration to a fatal outcome from the aneurysmal rupture, which is a rare cause of retroperitoneal abscess or pericardial effusion. The principles of management, including high clinical suspicion, an accurate diagnosis by imaging studies (arteriography or CT scan), prolonged effective antibiotic therapy, arterial ligation or wide excision of the infected lesion, intraoperative Gram's stain and culture, extra-anatomic bypass grafting through clean tissue planes, and prolonged postoperative follow-up, are indispensable to reduce morbidity and mortality.

Since there is no consensus as to the choice of an optimal prosthesis for aortobifemoral bypass, we have retrospectively evaluated the outcome with 162 Milliknit prostheses laid in cases of obliterating atherosclerosis. Such prostheses were preferentially used when the distal anastomosis were to be located on the deep femoral arteries. Intraoperatively, we noted the absence of fraying and the easy manipulation, owing to the flexibility and thinness of the wall, which are similar to those of the deep femoral artery: however, the blood loss before achieving complete tightness was greater than with most other knitted prostheses, and in 7.4% of the operated patients, defribination on clamp removal caused an additional bleeding averaging 1 litre. There was no graft sepsis during the postoperative period, may be because of the excellent healing of this prosthesis. One prosthesis only presented with excess dilatation accounting for thrombosis. The average length of follow-up was 3.6 years, the primary actuarial patency at 1, 5 and 10 years respectively was 98.7, 93.9 and 92.8%. Secondary patency at the same times was 99, 97.5 and 95.9%. These patency rates are among the best published in the literature. As a conclusion, this prosthesis is perfectly appropriate when the shunts must be located on thin femoral arteries, but a reduction of the intraoperative blood loss through an impregnation process would be desirable.

Seventeen infants less than 1 year of age have undergone heart (12), heart-lung (3), and lung (2) transplantation for end-stage cardiopulmonary disease. The infants undergoing heart transplantation had a mean age of 4.5 months (range, 19 days to 12 months) with the diagnosis of cardiomyopathy in 4 and congenital heart disease in 8. Four of the 8 patients (50%) had hypoplastic left heart syndrome. Actuarial survival at 1 and 2 years was 74% and compared favorably with the survival of older children at 1 and 2 years of 82% and 69%. The linearized rejection rate was less in infants as compared with children more than 1 year of age (0.61 versus 1.48 episodes per 100 patient days). In intermediate follow-up, no graft atherosclerosis has been noted. Immunosuppression has included a three-drug protocol of cyclosporine, azathioprine, and prednisone. A steroid taper to alternate day steroids or off completely by 6 months has been the goal and has been accomplished in 6 of 12 infants. Heart-lung and lung transplantation has been performed in 5 infants. One infant in each group died: 1 infant secondary to airway complications and sepsis and another due to pulmonary sepsis. A pulmonary lobe from a larger and older donor was transplanted into a 4-week-old infant as a single-lung transplant with good outcome. The 3 surviving infants are well 24, 18, and 2 months after transplantation. Obliterative bronchiolitis has not been clinically apparent in this group. These data support the clinical efficacy of heart, heart-lung, and lung transplantation in the first year of life.

We have previously shown the safety and efficacy of University of Wisconsin solution for hypothermic preservation of the human donor heart in a pilot group of 16 transplant recipients. The present study is a randomized clinical trial comparing University of Wisconsin solution to conventional preservation using crystalloid cardioplegia and saline storage within a 4-hour limit of ischemia. Heart transplant recipients (n = 42) were randomized into two groups: those receiving hearts preserved by University of Wisconsin solution, the UWS group (n = 22), and those receiving hearts preserved in the conventional manner, the CCS group (n = 20). Recipient age, gender, heart disease, and preoperative inotropic support and donor age, gender, and mean ischemic time in hours (UWS 2 hours 36 minutes, range 1 hour 36 minutes to 2 hours 53 minutes; CCS 2 hours 20 minutes, range 1 hour 20 minutes to 2 hours 44 minutes; p = not significant) were similar. Significant differences observed between the two groups included (1) mean time (minutes) from reperfusion to achieve a stable rhythm, (2) need for intraoperative defibrillations, (3) need for transient cardiac pacing, and (4) integrated postoperative creatinine kinase and aspartate aminotransferase release over 48 hours. There was no difference in postoperative electrocardiogram, endomyocardial biopsy, or hemodynamics. One UWS patient died of sepsis and another of a ruptured cerebral aneurysm. UWS is safe for donor organ arrest and preservation despite high viscosity and potassium concentration. When compared with CCS hearts, hearts preserved in UWS regained electrical activity more rapidly and had better myocardial protection as demonstrated by enzymatic analysis. Further investigation is required to determine the effects of UWS preservation on long-term survival, to determine the prevalence of rejection and graft atherosclerosis, and to test the ability of UWS to extend donor ischemic time in human cardiac transplantation.

Between August 1980 and October 1990 we treated 36 patients with home total parenteral nutrition (HTPN) with a cumulative treatment duration of 92 years. They included 14 females and 22 males ranging in age from newborn to 75 years, with a mean of 38 +/- 21. The 4 commonest indications for HTPN were short bowel syndrome (mainly due to mesenteric occlusion (50%), inflammatory bowel disease 14%), motility disorders (14%) and malabsorption (11%). All-in-one nutritional mixtures utilizing the big-bag technique were used for all patients. Broviac or Hickman catheters were implanted in 35 patients and an infusion port in 2. Infusions were administered during the night for 8-12 hours with a volumetric pump. 14 patients are still receiving HTPN (39%) while in 8 it was discontinued as they can maintain their nutritional status by the gastrointestinal route (22%). 14 patients have died (39%), 3 from HTPN-related causes (2 of sepsis and 1 of liver failure). Catheter-related sepsis was 0.42/year of HTPN. Other common complications were metabolic bone disease, deranged liver function and cholecystolithiasis. 80% were able to return to work, school, or housekeeping activities, or at least to take care of themselves and cope with HTPN unaided. Social rehabilitation was full or partial in 72% and only 29% were house-bound and needed major assistance. Patients with a poor life quality tended to be older and suffer from intestinal diseases as a manifestation of a systemic disorder, such as atherosclerosis or malignancy.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical and experimental evidence suggests that shock, arthritis, osteoporosis, colitis, leukemia, diabetes, wasting and atherosclerosis are mediated, in part, by interleukin 1 (IL-1). Inhibition of this cytokine has been a strategy for studying disease and for new drug development. A naturally-occurring IL-1 inhibitor (IL-1 receptor antagonist, IL-1ra) that blocks binding of IL-1 to its receptors has been cloned and produced in recombinant organisms. IL-1ra reduces the severity of sepsis, colitis, arthritis and diabetes in animals and is presently being tested in humans with arthritis, shock and myelogenous leukemia.

Acute acalculous cholecystitis is a virulent disease of uncertain etiology observed most commonly in critically ill patients. Although the precise mechanism is unknown, the most commonly postulated theories regarding its pathogenesis are bile stasis, sepsis, and ischemia. The role of ischemia in this process, whose etiology is multifactorial, has been difficult to elucidate. Consequently, we report two patients who developed acute acalculous cholecystitis without apparent risk for the disease other than severe visceral atherosclerosis. Both patients had symptomatic mesenteric vascular disease requiring revascularization and developed fulminant acalculous cholecystitis temporally related to exacerbation of their visceral ischemia. These cases suggest that patients with visceral atherosclerosis may be at increased risk for acute acalculous cholecystitis, perhaps due to impaired mucosal resistance when other factors, such as bile statis and sepsis, are also present.

A familial etiology was identified on the basis of family history in 16 (8.75%) of 184 patients undergoing cardiac transplantation at Stanford for endstage dilated cardiomyopathy (DC). These 16 patients, from 11 families, included 5 sibling pairs. To help determine optimal management of such patients, their case histories and posttransplant courses were reviewed. Mean age of patients at presentation was 23 +/- 15 years. In sibling pairs, duration of symptoms from onset to diagnosis was 14 +/- 5 weeks for the first sibling, but only 4 +/- 2 weeks for the second. Progressive cardiac enlargement was documented radiographically in siblings of transplant recipients in 2 families before the onset of symptoms. The posttransplant course with regard to rejection incidence, infectious complications, coronary artery disease and malignancy was similar to that of the 168 patients with nonfamilial DC. Actuarial survival at 5 years after transplantation was 80%. Thirteen patients (including all sibling pairs) are alive 1 to 11 years after transplantation. Sepsis was the cause of death in 3 patients, occurring during the early postoperative period in 2 and following retransplantation for graft atherosclerosis 7 years after the initial transplant in the third patient. Thus, diagnosis of DC in childhood or adolescence mandates evaluation and surveillance of family members, because this disease can progress rapidly. The favorable results of cardiac transplantation for familial DC suggest that it should be promptly considered for such patients with end-stage disease.
