The embolic type of popliteal entrapment syndrome.

The authors describe their experience with two patients who presented with clinical extremes of popliteal entrapment syndrome. One patient presented with acute ischemia and the second patient presented with a chronic Buergerian-like syndrome. The common denominator for both of them was embolic phenomena originating at the site of entrapment. Discussion is centered on pathogenesis of the embolic phenomenon, prevalence of distal arterial degradation and its clinical manifestation. The clue for differentiation from true Buerger disease is the angiographic pattern demonstrating apparently healthy distal arterial segments, confirmed by mandatory arterial biopsy. It is emphasized that in cases having acute embolic presentation the primary pathology should be treated concomitantly to revascularization.

Computed tomography diagnosis of primary aorto-enteric fistula.

Primary aorto-enteric fistulae are rare. Preoperative diagnosis is important but is difficult and cannot usually be confirmed by upper gastrointestinal series, aortography and endoscopy. Computed tomography demonstrating an abdominal aortic aneurysm with air bubbles in its wall and "soft tissue" mass posteriorly should raise the possibility of penetration of the aneurysm into the lumen of the bowel and related consequences (hematoma, sepsis, infected operating field).

Extracorporeal repair of renal artery branch lesions.

Complex renal artery lesions which formerly would have been treated by nephrectomy may now be reconstructed by extracorporeal surgery and autotransplantation. Our experience in 15 patients (17 operations) with renal artery lesions extending into its branches or confined to them is described. Two patients underwent separate operations on both sides. The indications for surgery were severe renovascular hypertension (10 cases), renal artery aneurysm, (5 cases) and deteriorating renal function (2 cases). Overall clinical results after a mean follow up of 3 years were considered excellent in 13 procedures (11 patients). Improvement in 2 patients and failure in the other 2, who ultimately underwent nephrectomy. Discussion is focussed on results, vascular indications, (namely aneurysm, stenosis, dissecting aneurysm and trauma) and surgical techniques. Preservation of functioning renal tissue should be the ultimate goal of renovascular surgery where the ex vivo technique, when indicated, will achieve favorable results in most patients.

Non-epileptic myoclonus and mitochondrial encephalomyopathy.

Two brothers presented to us with a progressive myoclonic syndrome with slight cerebellar symptoms. Neurological examination disclosed moderate cerebellar signs and pale optic discs; asymmetric, asynchronous and arrhythmic myoclonus, an arrthesthesic deficit and no muscular weakness. EEG background activity was moderately slow with no irritative discharges. CT was normal in both cases. Intermittent photic stimulation increased the frequency of the myoclonic jerks, which became bilateral and synchronous, progressing to a generalized tonic-clonic seizure. EPs and MRI in one case were normal. Anticonvulsant drugs were ineffective. The diagnosis of mitochondrial encephalomyopathy was based on the finding, in muscle specimens, of thickened basement membranes with myofibrillary degeneration and increased number of mitochondria peripherally distributed and with a dense granular matrix and some vacuoles. The clinical and EEG data suggest a subcortical origin for this type of myoclonic syndrome.

Clinical experience treating varicose veins in the aged.

Patients over 70 years of age suffering from varicose veins or complications of venous insufficiency formed 6.7 per cent of the population treated in our phlebologic clinic in 10 years. This group of patients is unable to perform intensive walking exercises and fails to use high-pressure elastic stockings; thus, most of the so-called "conservative armamentarium" is nonapplicable. This challenged us to find alternative or modified ways of treatment for this high-risk-for-surgery group. An isolated Trendelenburg procedure under local anesthesia, with sclerotherapy and/or transfixion sutures as an outpatient procedure, was used. In the case of stasis ulceration, patients were treated with sequential intermittent pneumatic compression including local hyperbaric oxygen and teaching the use of elastic support as an inhospital procedure. Both methods proved successful, thereby offering a more acceptable solution to one of the chronic problems of the older age group.

Changing trends in surgery for benign gallbladder disease.

Hospital charts and notes of 2181 consecutive cholecystectomies performed between 1969 and 1984 were computer analyzed. They were divided into three categories of patients operated on 5, 10, and 15 yr ago. The trends of change throughout this period were as follows: 1) The population operated on in the last 5 yr is older, the proportion of males, especially over 70-80 yr old, and diabetics, is growing constantly. 2) The frequency of acalculous cholecystitis and gangrenous changes increase; the same is true for common bile duct pathology and positive bile cultures. 3) There is a marked decrease in hospitalization time, postoperatively, without significant increase in rate of wound infection and thromboembolic phenomena, or mortality. It seems that there is no change in the frequency of gallstone-related pancreatitis and perforations of gallbladder. The same is disappointingly true for positive choledochal exploration index. We think that the subcostal approach, with rational prophylactic and therapeutic antibiotic regimen, contribute to the shortening of hospitalization time and the fixed rates of wound infection and herniae in scar. Prophylactic heparin given subcutaneously seems to avoid possible thromboembolic phenomena.

Primary leiomyosarcoma of the right common iliac artery--a rare finding and a cause of occlusive vascular disorder.

A case of primary intraluminal leiomyosarcoma of the right common iliac artery that presented itself by intermittent claudication is described. The diagnosis was established only postoperatively, based on examination of the endarterectomy specimen. No other primary tumor was found in the postoperative investigation and the patient received no further treatment. A review of the literature attests to the rarity of the diagnosis and the uncertainty regarding the mode of treatment.

TI-59 programmable calculator program for calculating predicted operative mortality in general surgery.

A program for the TI-59 programmable calculator for calculating predicted postoperative mortality is presented. Input data are based on handy, clinical, non-invasive pre-operative and operative parameters retrieved mostly significant in this respect by former multivariate logistic regression analysis of a broad data-base; their relative weights are incorporated into the program data base as basic coefficients. Considerations employed in its usage are discussed, as well as possible future technical and/or environmental modifications.
