This case report of a young man with a testicular germ cell-teratoma tumor illustrates the necessity of a multidisciplinary sequential approach to ensure chance of cure. The outcome of patients with advanced germ cell tumor depends on the optimal clinical management. Residual masses are frequent, and their histology can be different than the initial one (i.e., only residual mature teratoma cells or necrosis-fibrosis). Therefore a second surgery on residual masses with curative intent, may be important to optimalize the treatment and follow up. [less ▲]

Chronic rupture of abdominal aortic aneurysm (AAA) resulting in unusual clinical manifestations can occur if the resistance of structures surrounding the aorta is sufficient to contain hemorrhage. In this report, we describe five cases of chronic ruptured AAA in which the presenting feature was crural neuropathy. All patients were male with a mean age of 74 +/- 1.8 years. At the time of presentation, crural neuropathy had been ongoing for 3 to 9 weeks. In three cases, AAA was not initially suspected because an inadequate clinical examination was performed (not in the vascular surgery department) and because of the small diameter of the aorta in relation to the patient's morphology. Two patients had one episode of hypotension that was wrongly attributed to vagal attack. Abdominal CT scanning was always diagnostic of chronic rupture. In two cases, rupture was associated with erosion of the body of one or more vertebrae and laboratory evidence of inflammation, i.e., increase in sedimentation rate and fibrinogen level. The mean diameter of the AAA was 7.1 +/- 0.9 cm (range 5-10 cm). All patients underwent midline laparotomy, which was performed under emergency conditions in two cases, under semi-emergency conditions in one case, and electively in two cases. Perforation was consistently located on the posterolateral wall of the aorta and varied from 1 to 3 cm in length. Repair was performed using an aortobifemoral prosthesis in four cases, and a straight tube in one case. The patient who underwent emergency surgery died 4 days after the procedure. The remaining four patients recovered uneventfully and were discharged after 10 days. In the elderly, ruptured AAA should be included in the differential diagnosis of crural neuropathy. An episode of hypotension, regardless of its duration, in an elderly patient should be given serious consideration as a possible sign of ruptured AAA with ongoing retroperitoneal hemorrhage.

From January 1990 to December 1997, the authors observed 13 cases of fibromuscular dysplasia of the internal carotid artery. Four patients presented transient ischemic attacks, one amaurosis fugax, two suffered from a minor stroke, four had non-focalized ischemic cerebral symptoms and two were asymptomatic. At angiography, all patients showed a typical image of "string of beads". Seven patients were operated on. Six had endoluminal graduated dilatation, with rigid dilators up to 4.5 mm, associated with thrombendarterectomy of the bifurcation in three and to correction of a kink in one case. In one case a venous interposition graft was done to exclude a saccular microaneurysm of the dysplasic internal carotid artery. In another case, backflow was insufficient after endoluminal dilatation, and a long venous patch allowed to restitute a normal vascular lumen. There was neither postoperative mortality nor stroke. Six patients, asymptomatic or with non focalized symptoms, were treated medically. During a mean follow-up of 47 months, only one of the 13 patients developed a transient ischemic attack; the patient had not been operated on and received only medical treatment. Prevalence, etiopathology, diagnosis and management of fibromuscular dysplasia of the internal carotid artery are discussed. Fibromuscular dysplasia is a rare cause of cerebral ischemia. For asymptomatic lesions, a conservative approach seems appropriate. Surgery is only to be considered for symptomatic lesions. Surgical graduated endoluminal dilatation, where necessary combined with standard endarterectomy of the carotid bifurcation, is a safe, efficient and durable operation. Some complex cases of fibromuscular dysplasia may necessitate patch insertion or excision and graft interposition. [less ▲]

Aneurysms are characterized by dilation, i.e. expansion and thinning of all the arterial wall layers, which is accompanied by remodeling of the connective tissue. Genes involved in the regulation of tissue remodeling are therefore candidate genes. We analyzed TIMP1 and TIMP2 coding sequences in 12 individuals with abdominal aortic aneurysms (AAA), one individual with AAA and intracranial aneurysms (IA), four individuals with IA and two clinically unaffected individuals. We identified two nucleotide variants in both the TIMP1 and the TIMP2 coding sequences. All differences occurred in the third base positions of codons and were neutral polymorphisms. A significant difference was observed in the frequency of TIMP2 nt 573 polymorphism between 168 alleles from AAA patients and 102 control alleles. [less ▲]

Unruptured abdominal aortic aneurysm (AAA) is seldom recognized. Thus it is difficult to know whether the incidence of AAA in the general population is high enough to warrant routine screening at least in men after a certain age. Ultrasound screening studies to evaluate the incidence of AAA have been carried out in several English-speaking and Scandinavian countries. The purpose of this report is to describe the results of a study carried out in Belgium. All 65- and 75-year-old men living in the city of Liege, Belgium, were given the opportunity to undergo a free ultrasound examination. Only 41% of the target population was examined. AAA defined as abdominal aortic diameter of >30 mm was observed in 28 subjects (incidence: 3.8%). Mean abdominal aortic diameter was 34.7 mm. A diameter >29 mm was observed in 33 subjects (incidence 4.5%). Mean abdominal aortic diameter was 30.4 mm. On the basis of epidemiological data collected, a high-risk population for AAA was identified. Arterial hypertension (p < 0.05), previous coronary artery surgery (p < 0.05), and smoking (p < 0.06) were more common in subjects with than without AAA. The overall cost of screening was $18.175. The cost per AAA diagnosed was $551.00. [less ▲]

The decision on whether to operate or not abdominal aortic aneurysms (AAA) in elderly depends on the relative risk of the operation versus the natural course of the unoperated AAA. From January 1984 to December 996, 138 patients, aged 80 years and older, were referred to our department for an aneurysm of 40 mm or more (transverse diameter) of the infrarenal abdominal aorta (95 asymptomatic, 15 painful, and 28 ruptured AAA). For 58 patients with asymptomatic AAA, operation was denied at referral because of transverse diameter less than 50 mm (n = 21), patient refusal (n = 10) or unacceptable operative risk or poor general condition (n = 27). Thirty-four of these observed AAA were ultimately operated after a mean delay of 41 months because of aneurysm enlargement (n = 15), aneurysm tenderness (n = 6) or rupture (n = 13). Overall, 52 patients had immediate (n = 37) or delayed (n = 15) elective repair of their AAA, with an in-hospital mortality of 5.7%. Urgent operation was done for 21 patients with a painful AAA. Six patients died at hospital (28% mortality rate). Emergent surgery was applied to 41 patients with ruptured AAA (including 13 AAA who ruptured during surveillance). The operative mortality in this subgroup attained 68%. Follow-up for the 77 survivors and the 24 non-operative patients averaged 43 months. The 5-year survival (operative mortality included) is 47% for electively operated patients, 30% for urgently and 20% for emergently operated patients. For comparison, the 5-year survival of an age and sex matched Belgian population is 63%. For the 24 medically followed AAA, the 5-year survival was 33%. In six cases, the cause of death was rupture of the AAA. Of the 58 patients for whom operation was initially not considered, 19 (33%) presented AAA rupture (13 operated in emergency and 6 who never came to surgery). The operative outcome of AAA repair in octogenarians is less favourable than in the younger age group (3.6% mortality after elective repair, 44% after operation for AAA rupture, according to our institution data). The authors conclude that AAA surgery should not be denied to octogenarians on the basis of advanced age alone. They recommend a straightforward surgery for otherwise healthy octogenarians with AAA of 50 mm diameter, surveillance up to 60 mm for high-risk patients and no surgery for unfit, bedridden or demented patients.

The medical records of nine patients (five female and four male, mean age 58 +/- 5 years) presenting with a carotid chemodectoma between 1983 and 1995 were reviewed. In two cases (22%) the diagnostic was not suspected at the time of initial presentation. The most common complaint was a swelling in the anterolateral region of the neck. One patient (11%) presented with a preoperative peripheral nerves deficits (vagus and hypoglossal palsies and Horner's syndrome). Two tumours were embolized preoperatively with polyvinyl alcohol particles. Complete surgical excision was possible in each patient and the plane of resection was adventitial. In three cases, early ligation of the external carotid artery facilitated the resection. In two patients, the vagus nerve was sacrificed because of tumour involvement. No operative mortality was observed and no vascular complication occurred. In addition to the patient with preoperative neurologic symptoms, three patients developed peripheral nerve deficits (vagus and hypoglossal nerves) postoperatively. Two of these deficits were transient. These peripheral neurologic complications were observed with the largest tumour sizes. Two cases were malignant (lymph nodes and bony metastases). These two patients received postoperative radiotherapy. The mean follow-up period 63 +/- 19 months. No patient developed local recurrence during the follow-up. Two patients died during the follow-up, one for condition unrelated to their disease and the second from metastatic dissemination. In conclusion, carotid chemodectomas may be safely resected. The best way to minimize the rate of complications is to operate them at an early stage of evolution. [less ▲]

Only a few cases of combined liver and heart transplantation have been reported in the literature, and no standard surgical procedure has yet been established. We report the successful transplantation of both liver and heart in a 28-year-old patient suffering from homozygous beta-thalassemia. We used Belghiti's technique of inferior vena caval flow preservation for liver transplantation, which avoids inferior vena cava occlusion by a side-to-side caval anastomosis. Applied to combined liver and heart transplantation, preservation of caval flow during liver transplantation may allow early discontinuation of cardiopulmonary bypass and, thus, minimize the general consequences of prolonged bypass.

Two cases of life-threatening haematuria, secondary to an uretero-arterial fistula, are reported. Both cases present predisposing causative factors. One patient had a combination of previous aorto-bifemoral bypass grafting, an iliac artery aneurysm (retrogradely perfused), and an indwelling ureteral stent for ureteral compression. The other patient had previous aortoiliac surgery and obstructive uropathy with chronic urinary tract infection. Preoperative diagnosis of uretero-arterial fistula was made in only one patient. He was successfully operated (exclusion of the iliac aneurysm). In the other patient, nephrectomy was attempted to control reno-ureteral bleeding of unknown origin. Fatal recidive of brisk haematuria occurred some days later. Factors contributing to the development of uretero-arterial fistula, their diagnosis and optimal treatment are discussed. [less ▲]

The relationship between atherosclerosis and abdominal aortic aneurysm development is well known. Atherosclerosis cannot explain the whole mechanism. Genetic characters of mechanisms leading to abdominal aortic development is obvious from this study and others. Our study evidences an increased metalloproteases activity in aortic wall proportionally to the size of the abdominal aortic aneurysm. A decrease of aortic wall elastin is evidenced proportionally to the AAA size. Extractable collagen is significantly increased in the aortic wall of patients operated on for aortic rupture. [less ▲]

A 76-year-old man underwent surgery for an infrarenal aortic aneurysm reaching 6 cm in maximal transverse diameter. The aorta was crossclamped below the level of the renal arteries. A tube graft was interposed and tend between the infrarenal aorta and the aortic bifurcation. Due to leakage on the suture line two consecutive episodes of crossclamping for a total duration of 40 min. were required. No hypotension was noted during or after the procedure. After operation, the patient complained of difficulties to move both legs and neurologic examination demonstrated paraparesis, with mild sensory deficit. Faecal and urinary incontinences were also noted and urodynamic testing demonstrated sphincterovesical palsy. Nuclear magnetic resonance imaging detected an ischaemic zone in the spinal cord at the level of T11. Faecal incontinence and motor deficit partially resolved but no bladder function recovery was observed. Spinal ischaemia is a rare complication after abdominal aortic surgery. Several risk factors have been suggested which include level and duration of the aortic crossclamping, possible interruption of the spinal cord blood supply via the greater medullary artery (the so-called artery of Adamkiewicz), presence of intra- or postoperative episodes of hypotension, atheromatous embolization, underlying occlusive arteriosclerosis of spinal arteries, and respect or not of the hypogastric circulation. In our case, the duration of the crossclamping and interruption of the blood flow in lumbar arteries probably supplying the distal spinal cord were likely contributive factors. [less ▲]
