Arteriovenous fistula of the internal mammary artery (combat injury): transcatheter intravascular coil occlusion.

A case of arteriovenous fistula of the left internal mammary artery occluded by Gianturco coil is reported. A 26-year-old male suffered multiple explosive injuries. Right heart failure developed postoperatively. Digital subtraction angiography demonstrated arteriovenous fistulas between the left internal mammary artery and left subclavian and innominate veins. Considering previous multiple surgical interventions and severe general condition of the patient, both arteriovenous fistulas were successfully occluded by transcatheter placement of a Gianturco coil.

Our 10-year experience with embolized Wilms' tumor.

In the Department of Pediatric Surgery, Clinical Hospital Center Rebro in Zagreb, during the last 10 years a new method of invasive diagnostic and at the same time therapeutic procedure for the treatment of Wilms' tumor has been introduced. The treatment is preoperative Percutaneous Transcatheter Intraarterial Embolization (PTIE) of the renal artery. The aim of this procedure is to reduce vascularization, to decrease the mass of kidney affected by the tumor, to separate it from the surrounding tissue, to decrease intraoperative spillage of malignant cells into the blood stream and their metastasizing. As a result nephrectomy is easier to perform. It has been confirmed that it is best to perform nephrectomy 48 hours after embolization. The authors present their own experience with 33 patients, ranging from 1 to 16 years of age.

Therapeutic embolization of aneurysmal bone cyst.

Results of therapeutic embolization of aneurysmal bone cysts in five patients are described. Transcatheter arterial embolization was performed with Ivalon and Gelfoam particles and Gianturco coils. The postembolization period was characterized by complete relief of pain and decrease in size of the aneurysmal bone cyst in all patients. In patients whose follow-up was longer than 12 months, sclerosis and recalcification of bone were present. There were no complications.

Percutaneous transluminal renal angioplasty (PTRA) as a method of therapy for renovascular hypertension in children.

The results of PTRA in treatment of renovascular hypertension in four children aged 5, 7, 13 and 15 are presented. All patients suffered from severe hypertension. Tests showed all of them to have fibromuscular dysplasia stenosis of the main renal artery and significant lateralization of renin levels. One suffered from associated polycystosis of kidneys and in another the renal artery stenosis was bilateral. In all patients successful patency was achieved. In one patient, the arterial pressure after PTRA was normalized, while in the others it was considerably improved. Two patients, tested 8 and 12 months after PTRA, were lost to further follow-up. In one of the remaining two, stenosis and hypertension reappeared 5 years after PTRA. After autotransplantation the patient was normotensive. In the other, also 5 years later, recurrent hypertension appeared related to the associated polycystosis.

[Effect of improved surgical anesthesiologic factors on the results of treatment of aneurysms of the abdominal aorta].

The purpose of this study was to compare the recent results of the abdominal aortic aneurysm (AAA) surgery, with the results for the patients operated ten years ago, and to identify the factors influencing the operative results. Two groups of patients were selected using a retrospective case series study. First group of patients (A) consisted of 32 cases operated in the period between 1984 and 1986, and the second group (B) consisted of those operated ten years later (from 1994 to 1996). Mortality rate, presence of risk factors, demographic data, and operative factors were analyzed and compared between the groups. The mortality rate decreased from 10.7% in period A, to 5.3% in period B for elective operations, and from 75% to 44.4% for emergency operations. The prevalence of straight graft technique in period B showed statistically significant difference compared to period A (p < 0.005). Besides, the operating time and the amount of the transfused blood between the groups differed significantly (p < 0.05). On the basis of this data, we concluded that the modifications in the operative technique, as well as the increased number of operations within the second period led to the decreased mortality rate in patients operated for AAA.

[Modern diagnosis and treatment of pheochromocytoma in children].

Pheochromocytoma is a rare tumor of chromaffin tissue of the adrenal gland that synthesizes, stores and releases cathecolamines. In 10% of the patients it arises outside the adrenal gland, and has been called paraganglioma. The following study describes our experience in the diagnostic process and treatment of pheochromocytoma in two children, a 8-year-old boy with the right ureteral paraganglioma, and a 8-year-old girl with pheo-chromocytoma of the leftsuprarenal gland. Characteristic clinical features with predominant signs of hypertension, as well as the diagnostic flow diagram, have been presented. We have analysed recent diagnostic possibilities, sensitivity of diagnostic methods (ultrasonography, CT, selective angiography and J131 MIBG scintigraphy), indications for their use, and the importance of appropriate preoperative management. The major role of the J131-metaiodobenzilguanidine scintigraphy in diagnostic assessment, especially in precise preoperative localization and postoperative verification of tumour removal, has been stressed.
