In recent years percutaneous closure of small and medium- sized patent arterial ducts has been achieved using occluding spring coils. We describe our experience in 93 patients with this tec, using a snare to facilitate the procedure in most. All patients had a clinically apparenpatent arterial duct and had undergone attempts at transcatheter closure at a mean age of 6.8 years. In 1, the duct was a residual lesion following surgical ligation, and in 5 it was a residual following attempted closure with the Rashkind double-umbrella. The mean narrowest diameter of the ducts was 2.1 mm.

In our 93 patients implantation was successful in 92 (99%), using 1 coil (82 patients), or 2 (10 patients), and in 1 by a combination of a double-umbrella device and an occluding spring coil.

The mean fluoroscopic screening time for the whole group was 22.8 minutes, which decreased to 16.8 minutes in the last 50 patients. The coil embolized in 7 patients, but was retrieved in 6 and the ducts were subsequently occluded with another coil. In 1 patient the coil was left in a distal small branch of the left pulmonary artery and the duct was successfully occluded with a double-umbrella.

Color-Doppler echocardiogram performed the morning after placement of the coils showed residual leaks in 18%. At mean follow-up of 24.6 months repeat imaging showed residual leaks in only 3 of these patients (3%).

We conclude that occlusion of small to medium-sized ducts using coils appears to be effective and is the treatment of choice. The use of a snare to hold and manipulate the coil as it is delivered improves control of the coil, the accuracy of its placement, as well as giving complete occlusion of the ducts.

Intestinal transplantation, which until recently has been considered an experimental procedure, is now undergoing considerable change and becoming a standard treatment for patient with intestinal failure. The major improvement in results is due to the introduction of new immunosuppressive agents that have led to significant reduction in acute rejection. Nevertheless, reduction in severe infectious complications, which are the main cause of mortality after transplant, as well as improved techniques for early diagnosis of rejection are needed before intestinal transplantation can be widely used.

We describe our experience in post-transplant follow-up of a woman, aged 32-years, who had undergone intestinal transplantation for short bowel syndrome after extensive bowel resection.

The Mitrofanoff Pouch in Lower Urinary Tract Reconstruction

The Mitrofanoff principle, first described in 1980, consists of implanting a tubular organ such as the appendix, ureter, or fallopian tube into the wall of the bladder (or urinary reservoir) to create a non-refluxing, catherizable urinary conduit. Between 1993-1996, 7 men and 1 woman (aged 48-64, average 59) underwent radical cystectomy and urethrectomy combined with the creation of a MAINZ I urinary reservoir (based on the Mitrofanoff principle). In men the indication for the procedure was the diagnosis of invasive transitional cell carcinoma of the bladder with involvement of the prostatic urethra. All patients had refused urinary diversion to an ileal conduit because of its deleterious effect on the quality of life.

In all patients the postoperative course was uneventful, apart from intraperitoneal urinary leakage from the reservoir in 1, successfully managed conservatively. The patients have gained full control of urinary drainage, performing intermittent self-catheterizations every 4-5 hours. In 3 patients there were difficulties with catheterization due to stenosis of the conduit, usually at the skin level. None have suffered leakage from the reservoir, during the day, even when it was full.

Our experience shows that creation of a continent urinary reservoir according to the MAINZ I technique is an excellent surgical solution for patients in whom the creation of an orthotopic reservoir is impractical. The use of the umbilicus as a stomal site preserves normal body image and thus does not interfere with quality of life as in those undergoing radical cystectomy.

Isolated secundum atrial septal defect is one of the most common congenital heart defects. Surgical closure is the treatment of choice but is associated with a chest scar, some morbidity and a relatively long recovery and the use of cardiopulmonary bypass. Transcatheter closure of secundum atrial septal defect is therefor an attractive approach.

3 children, aged 5-10 years, underwent successful transcatheter closure of moderate to large central atrial septal defects with the Cardioseal device. The procedures were performed under x-ray and transesophageal echocardiographic guidance.

Our initial experience, and that of others, indicates that transcatheter occlusion of secundum atrial septal defects is safe and effective and can be an appropriate alternative in approximately 60% of patients.

Kimura's disease is a rare angiolymphoid proliferative disorder of soft tissue characterized by subcutaneous swelling and a predilection for the head and neck. There are usually enlarged regional lymph nodes, eosinophilia and elevated sedimentation rate and IgE levels. A 26-year-old women with subcutaneous masses in the submandibular area is reported. The diagnosis of Kimura's disease versus angiolymphoid hyperplasia is discussed.

Our experience with living-related liver transplantation is described. In 2 boys and 1 girl, aged 4-4.5 years with acute, fulminating hepatitis A, the presence of very severe jaundice (bilirubin levels > 18 mg%) associated with severe coagulopathy (INR>10) and encephalopathy indicated the need for urgent liver transplantation. In all 3 cases the left lateral hepatic segment of a matched blood type parent was transplanted. None of the donors suffered a serious complication postoperatively and all returned to full activity in 6-16 weeks. The post-transplantation course was uneventful in 1 child, but in the other 2 there was hepatic arterial thrombosis in 1 at 1 day and in the other at 8 days post-transplantation. Early detection of arterial thrombosis by Doppler sonography permitted salvage of the 2 hepatic grafts after thrombectomy and re-anastomosis. In 1 of these 2 children an anastomotic biliary stricture was found 2 months after transplantation. It was corrected at surgery and a percutaneous stent was inserted. All 3 children are alive with normal graft function at 2, 7 and 8 months post-transplantation, respectively. This initial experience indicates that living-related liver transplantation is feasible in Israel. The technique might help to solve our severe organ shortage for children awaiting liver transplantation.

The skeletonized internal mammary artery (IMA) is longer, and its immediate spontaneous blood flow is greater than that of the pedicled IMA, thus providing increased versatility for complete, arterial myocardial revascularization without the use of saphenous vein grafts. From April 1996 to May 1997, 583 patients underwent coronary artery bypass grafting here and in 415 (71%) complete arterial revascularization was achieved using bilateral skeletonized IMA. The right gastroepiploic artery was used in 57 (13%); there were 329 males (79%) and 86 women (21%); average age was 64 (30-87) and 175 (36%) were older than 70; 131 (32%) were diabetics. Average number of grafts was 3.2 (range 2-6 grafts). At 30 days, 5 (1.2%) had died and there had been 6 perioperative infarcts (1.4%), 5 CVA's (1.2%), and 6 had sternal wound infections (1.4%). Up to 1-12 months of follow-up was achieved in 409 (99%). Late mortality was 1.4% (of which 3 were noncardiac). 394 (97%) were angina-free at latest follow-up. We conclude that arterial revascularization using bilateral skeletonized IMA is safe, as postoperative morbidity and mortality are low, even in old and diabetic patients.

Budd Chiari syndrome is a rare disorder resulting from occlusion of hepatic venous drainage by hepatic vein thrombosis or by a membranous web in the inferior vena cava. In western countries the commonest causes are myeloproliferative disorders and hypercoagulable states. Presentation may be acute with rapid accumulation of ascites and hepatic failure, or subacute with symptoms developing over a few months. A chronic progressive form has also been described. On presentation there is usually abdominal pain, ascites, and hepatosplenomegaly; hepatic encephalopathy is found in about a third. Noninvasive, ultrasound-Doppler is recommended in diagnosis, and has a high correlation with hepatic venography. Liver biopsy is required for therapeutic decisions. Those with advanced hepatic failure or severe fibrosis on liver biopsy are referred for hepatic transplantation. When biopsy shows only hepatic congestion and inflammatory infiltrates, portosystemic shunting is recommended. We present a 61-year-old woman with ascites and hepatosplenomegaly that had developed over the courses of a few months. Budd-Chiari syndrome with chronic myelofibrosis and congenital protein C deficiency were diagnosed. Portosystemic shunt was performed but death from sepsis followed shortly.

With limited organ resources and an increasing number of candidates for liver transplantation, the world-wide trend is towards using liver allografts from donors older than 60 years. This strategy, however, may be hazardous because of the known correlation between advanced donor age and graft dysfunction. Since January 1996, each of 5 patients received a liver allograft from a donor older than 60 years. Preservation time in these cases was shortened as much as possible and liver allografts were used only if there were no other potential risk factors for primary nonfunction. Mean cold ischemic time was significantly shorter in this donor group (7.8 hrs) than for livers from 28 younger donors (10.2 hour; p<0.01). 3 of the 5 grafts from older donors had normal function immediately. The other 2 initially had biochemical features of preservation injury, but graft function returned to normal within the first week after transplantation. All 5 patients currently have normal graft function, with follow-up ranging from 3-8 months. There was no difference between the 5 recipients of grafts from older donors and 28 adult recipients of grafts from younger donors in extent of preservation injury and in immediate graft function. We conclude that in countries with limited organ resources, such as Israel, liver allografts from older donors can be used within defined limits and minimal preservation time.

In Israel ovarian cancer ranks among the most common malignant diseases in women. It is also one of the main causes of death from cancer in females in this country. Our population is composed of immigrants from diverse social, cultural, and geographical backgrounds, and only a sector of the inhabitants, mainly the younger generation, is Israeli-born. This study evaluates the trends of epidemiological and clinical data on ovarian cancer during 3 decades, 1960-1989, and includes a total of 5,786 cases of ovarian cancer. Information was obtained from the Central Israel Cancer Registry of the Ministry of Health and from the Central Bureau of Statistics. The incidence was stable during the survey period and was about 15-17/100,000 in women over the age of 15. Most (90%) were diagnosed over the age of 40. In women of European/American origin the incidence of ovarian cancer is 3 times greater than in women of Asian/African origin. The rate in the Israeli-born is between those of the other 2 groups, but closer to that of the European/American group. Over 70% were diagnosed with advanced disease (stage III-IV).

Prognosis improved during the period of the study: 5-year survival was 19% in the early 60's and 31% in the 80's. During the last decade of the survey improvement was mainly in 2-year survival (from 38.5% to 60%).
