Renal artery pseudoaneurysm after blunt abdominal trauma.

Renal artery pseudoaneurysms are rare after blunt abdominal trauma; only 11 cases have been previously reported. Pseudoaneurysms are caused by decelerating injuries of the renal artery after major falls or automobile accidents. Patients may be asymptomatic for many years, and the pseudoaneurysm may expand and rupture before diagnosis or treatment. The patients in four untreated cases died. The diagnosis of renal artery pseudoaneurysm can be made by Doppler sonography, computerized tomography, renal perfusion imaging, or contrast angiography. Treatment requires either surgical or percutaneous intervention. Renal salvage was possible in five of the seven patients treated. We report two additional patients with successful outcomes after surgical intervention.

Mycotic aneurysm of the popliteal artery secondary to tuberculosis. A case report and review of the literature.

Mycotic aneurysms of the popliteal artery are rare; 33 cases have been reported in the literature. The treatment of choice is a large excision with extra-anatomic revascularization. In situ revascularization is sometimes possible. To the best of our knowledge, tuberculosis has never been reported as a causal factor of mycotic aneurysms of the popliteal artery. We report a case of a recurrent tuberculous false aneurysm of the popliteal artery. After 2 attempts at in situ revascularization, the femoral artery was ligated with no distal ischemia.

[Cardiac failure caused by renal arteriovenous fistula fifty years after nephrectomy. A new case and review of the literature].

Arterio-venous fistulae are rare after nephrectomy. They are the cause of congestive cardiac failure. This case report has two particularities: an exceptionally long interval, 50 years after nephrectomy, and a severe hypertension due to stenosis of the contra-lateral renal artery. Surgical treatment of these fistulae is essential and gives excellent results with rapid regression of the signs of cardiac failure. Percutaneous embolization is an alternative in patients with a high surgical risk. All previously reported cases are reviewed (n = 72) with their aetiological, clinical and therapeutic features.

Concomitant cerebral, brachiocephalic trunk, and cardiac revascularization. An unusual case.

Extensive transthoracic brachiocephalic revascularization is rarely performed. Instances of this operation performed concomitantly with cardiac revascularization and carotid endarterectomy have been reported in fewer than 10 cases in the literature. We report the case of a patient requiring complex brachiocephalic revascularization associated with coronary bypass grafting and a left carotid endarterectomy.

Aberrant right subclavian artery aneurysm--a surgical review.

Aneurysms of an aberrant subclavian artery are rare. They are usually secondary to atherosclerosis. Dysphagia is the most common presenting symptom. The diagnosis of the lesions is easily established by CT scan or MRI. Biplane arteriography is necessary in order to clearly analyse the aortic arch and its branches. Surgical resection is usually indicated. We treated a patient who suffered from an aneurysm of an aberrant subclavian artery. The surgical technique is detailed as well as a review of all the surgical cases of the literature.

Spontaneous cholesterol embolization. A rarely reported entity.

Cholesterol embolization sometimes occurs after invasive procedures involving manipulation of the aorta or its major branches, and less commonly occurs after thrombolytic therapy for acute myocardial infarction. Rarer still is spontaneous cholesterol embolization, a case of which we now report. Our patient experienced peripheral embolization, the origin of which was traced to the infrarenal aortic segment and the common iliac vessels. Aortoiliac reconstruction was successful; we believe that surgical management of this condition should be performed in selected cases.

Infected infrarenal aortic aneurysms: when is in situ reconstruction safe?

Twenty-five infected infrarenal aortic aneurysms operated on between 1968 and 1989 were reviewed. They were classified into post-embolic (mycotic) aneurysms (group I), infective aortitis (group II), and infected atherosclerotic aneurysms (group III). Aortoduodenal fistulas were found in eight patients and aortocaval in two. Five patients were operated on in a state of shock, and 12 had preoperative positive blood cultures. Surgical procedures included in situ reconstruction of the aorta (n = 21) and extra-anatomic bypass associated with aneurysmal resection (n = 4). In 19 patients, prostheses were covered with omental flaps, and antibiotics were continued for more than 6 weeks in all patients. In patients who underwent in situ reconstruction, three deaths were related to the initial surgery. All surviving patients were regularly followed up, and none showed any sign of late septic recurrence. In patients who underwent extra-anatomic bypass, two died in the postoperative period, one underwent reoperation 2 years after the initial surgery, and the last patient is doing well. Positive postoperative blood cultures (n = 4) revealed persistent sepsis: two cholecystitis, one spondylitis, and one aortic infection. An exhaustive review of the literature was performed; clinical, bacteriologic, and operative features and results were analyzed; prognostic factors were evaluated; and a practical therapeutic approach was suggested. The importance of preoperative diagnosis, complete resection, debridement of infected tissues, omental flap coverage, and long-term antibiotic therapy with regular computerized tomographic scanning follow-up is stressed.

Traumatic rupture of the thoracic aorta--case report.

Acute traumatic rupture of the thoracic aorta due to blunt trauma is a relatively common injury after deceleration accidents. However, only one fifth of these patients survive to reach medical facilities. The limiting factor to successful management is early diagnosis and prompt treatment. A case of acute traumatic rupture of the descending aorta due to blunt trauma is presented. Diagnostic and management modalities are discussed.

Spontaneous cholesterol embolization--a rare clinical entity.

Embolization of cholesterol crystals from atheromatous plaques is a rare entity most often seen after invasive procedures involving manipulation of the aorta. Spontaneous CE has been reported in very rare cases. Peripheral signs include livedo reticularis, muscle pain and palpable pulses. Depending on the site of the responsible plaque, emboli may involve visceral organs and produce a systemic illness. Diagnosis is confirmed using skin, muscle and/or renal biopsies. Surgery is recommended when the atheromatous disease is localized to a unique segment which can be replaced.

Arterial thrombosis: a rare complication of the nephrotic syndrome.

Arterial thrombosis is a rare complication of the nephrotic syndrome, occurring mainly in men. Two cases of arterial thrombosis are described, the first affecting a 54-year-old man in whom aortic thrombosis initiated the nephrotic syndrome and who relapsed 1 year later resulting in graft thrombosis, the second affecting a 15-year-old male patient with extensive popliteal and distal arterial thrombosis, followed by recurrent venous bypass thrombosis. A review of the literature shows that arterial thrombosis occurs primarily in the femoropopliteal, renal and coronary arteries. The genesis of arterial thrombosis in patients with nephrotic syndrome involves increased blood viscosity, platelet adhesion and aggregation, high levels of fibrinogen, low levels of serum antithrombin III, diuretic agents and steroid therapy. For high-risk patients with low levels of plasma albumin or those receiving steroids, anticoagulation therapy should be introduced to prevent thrombosis. Urine protein should be evaluated in patients with arterial thrombosis of unknown origin.

Arterioureteral fistula after extended resection of pelvic tumors: report of three cases and review of the literature.

Arterioureteral fistulas are rare. Three patients with arterioureteral fistulas complicating extended resection of pelvic tumors associated with bilateral cutaneous ureterostomy in the right lower quadrant are reported. In one case, the fistula involved the left ureter, the right common iliac artery, and the inferior mesenteric artery. Pathological iliac artery, pelvic cancer, or operated ureteral stones are often incriminated in the genesis of ureteroarterial fistulas. Insertion of a ureteral catheter has been found to be the main promoting factor. The common iliac artery is involved frequently. Clinical presentation is often limited to gross hematuria, whereas complementary investigations have not proved to be sensitive. Surgical treatment is often complex, but must be undertaken early, even in the absence of absolute proof of diagnosis, in order to preclude uncontrollable massive hemorrhage.

Emergency arteriography in the assessment of penetrating trauma to the lower limbs.

One hundred emergency arteriographies (EA) were performed in 87 patients with lower limb trauma due to high-velocity missiles. Thirteen patients had bilateral injuries. In 79 cases, EA findings were positive and led to emergency surgery. In 76 cases an arterial injury was found and treated, a positive predictive value of 96% (76/79). In the other 3 cases, no arterial lesion was found (3 false positives). Among the 21 patients with normal findings from angiography, 10 had surgical exploration because of high clinical suspicion of vascular injury. Arterial injury was found in 2 cases (2 false negatives). In 8 patients, arteriography modified the surgical procedure. In the 11 remaining patients, clinical and echo Doppler follow-up results were normal, a negative predictive value of 90% (19/21). Sensitivity was 97%, specificity 86%, and accuracy 95%. These data show that arteriography in stable patients is a safe and accurate procedure. It permits avoidance of unnecessary surgical exploration in selected patients and helps modify the surgical procedure.

[Recurring arterial thrombosis in the adult during a nephrotic syndrome. Report of a case and review of the literature].

A 55 year old male with idiopathic nephrotic syndrome (minimal glomerular changes at light microscopy) developed recurrent arterial thrombosis (aortic, popliteal and prosthetic) combined with recurrent proteinuria. Fourty nine cases of adult arterial thrombosis associated with nephrotic syndrome are reviewed. This complication mainly affects the coronary, iliac and femoral, renal and cerebral arteries. Any type of nephrotic syndrome can be involved. The hypercoagulable state predisposes to thromboembolic events. Corticosteroid induced thrombotic episodes have been described during nephrotic syndrome. Therefore anticoagulant therapy is mandatory when steroid therapy is used.

Thoracic splenosis. Case report and literature review.

Thoracic splenosis is the autotransplantation of splenic tissue into the thoracic cavity after thoracoabdominal trauma. We report a case of thoracic splenosis in a 35-year-old woman who had had a thoracoabdominal gunshot wound 12 years earlier. A review of the literature revealed 15 cases already reported. All patients had an asymptomatic thoracic lesion discovered on a plain chest film 9 to 32 years (mean 16) after the initial accident. In 13 cases an operation was necessary to establish the diagnosis. In two cases technetium 99m and indium 111 scans established the diagnosis.

[Thoracic splenosis. Review of the literature apropos of a case].

Thoracic splenosis consists of autotransplantation of splenic tissue in the thorax following thoraco-abdominal trauma. The authors report a case of thoracic splenosis in a 35 year old woman who suffered a thoraco-abdominal gunshot wound 12 years previously. Sixteen cases of thoracic splenosis have been reported in the literature. Always asymptomatic, the thoracic lesions were discovered by chance on chest x-rays performed for various reasons 9 to 32 years after the initial trauma. Surgery was required in 13 patients in order to establish the diagnosis. In 2 cases Tc99 and Indium 111 isotope scans revealed the diagnosis, avoiding the need for surgery.
