[Surgical treatment of chronic mesenteric ischemia].

A 44-year-old woman with chronic abdominal pain and weight loss is presented. 1 year after onset of symptoms and following multiple diagnostic procedures, angiography revealed high grade stenosis of the celiac and superior mesenteric arteries at their origins. Bypass grafts of Goretex were implanted from the infrarenal aorta to both arteries beyond the narrowed segments. 1 year after surgery the patient has regained her weight and is feeling well.

Congenital aplasia of the deep veins of lower extremities in children: the role of ascending functional phlebography.

Eighty-two children with vascular diseases underwent phlebography. Congenital aplasia of the deep venous system of the lower extremities was diagnosed in 10 children. With ascending functional phlebography, three anatomic variations with different degrees of venous dysfunction were defined: aplasia of the femoral vein with collateral drainage into the common femoral vein, aplasia of the femoral vein with drainage into the internal iliac vein, and total aplasia with drainage into the axillary vein. The phlebographic findings correlated with the symptoms. Patients with type a aplasia had no clinical and radiologic signs of venous insufficiency. Patients with types b and c aplasia had severe venous insufficiency that necessitated supportive treatment. Palliative surgical procedures such as hemorrhoidectomy, clitoridectomy, and excision of bleeding vascular nevi were performed. Ligation or excision of the dilated superficial veins (usually the main channels for venous drainage from the extremity) is absolutely contraindicated. Ascending functional phlebography is therefore essential for correct diagnosis and planning of future therapy.

Transluminal dilatation of the subclavian artery.

Transluminal dilatation of seven left subclavian arteries and one right subclavian artery was attempted in seven patients. Dilatation was successful in four left subclavian arteries and the single right subclavian artery treated. Five of the patients suffered from cerebral symptoms as well as ischemia of the upper limb, one had only cerebral symptoms and another had only arm claudication. All patients also had significantly reduced systolic blood pressures in the brachial artery. Standard techniques for percutaneous transluminal angioplasty (PTA) were employed, using the femoral route six times and the axillary route four times. No complications occurred. All patients were permanently given a maintenance dose of antiplatelet treatment with dipyridamole 75 mg tds after PTA. Follow-up of up to 36 months, indicates that angioplasty can be accomplished in the stenosed subclavian artery with relatively little hazard. Patients with hemodynamically significant stenoses should be considered for PTA if their symptoms and signs warrant such therapy.

Multiple arterial aneurysms.

An 8 1/2-yr-old boy presenting with excruciating abdominal pain had two abdominal aortic aneurysms excised. Angiography demonstrated additional aneurysms of the right brachial artery, right renal artery, right internal iliac artery and multiple aneurysms of the right popliteal and tibialis posterior arteries. The patient does not suffer from any of the conditions generally recognized to be associated with aortic and multiple arterial aneurysms. No similar case could be found in the English language literature.

Control of massive retroperitoneal bleeding associated with pelvic fractures by angiographic embolization.

Continuous retroperitoneal bleeding may be an immediate life-threatening complication of pelvic fractures. While surgical control of the bleeding vessels has been advocated in these cases, today angiographic embolization of the branches of the internal iliac arteries is proving to be the treatment of choice. This is a relatively simple, safe, prompt and effective method of controlling the hemorrhage. It avoids the disadvantages of surgery, general anesthesia, loss of the tamponade effect of the retroperitoneum when opened, and the not uncommon difficulty of identifying and ligating the bleeding vessels. Two cases in which massive retroperitoneal bleeding associated with pelvic fractures was controlled by angiographic embolization are described, illustrating the importance of early angiography.

Six-year experience with bovine arterial graft for hemodialysis.

During the last six years 29 bovine arterial grafts were implanted in 21 patients. A total of 186 angioaccesses had been performed on these patients prior to the insertion of bovine graft. Nineteen grafts (65.5%) are still patent with a mean patency time of 43 months. Ten grafts (34.5%) failed, the main cause of failure being infection. The cumulative patency of failed grafts was 46 months.

Reversal of ergotamine-induced arteriospasm by mechanical intra-arterial dilatation.

Two patients with imminent gangrene of the extremities caused by ergot-induced arteriospasm underwent mechanical dilatation of the arteries when conventional measures such as anticoagulation, vasodilation, and sympathetic blockade produced no improvement. Dilatation by a balloon-tipped catheter produced an immediate and sustained reversal of the arteriospasm, together with a dramatic relief of symptoms and signs.

Bronchial malignant melanoma.

We describe a case of malignant melanoma presenting initially as an endobronchial lesion located in the left main bronchus causing total atelectasis. This resolved with radiation therapy. Widespread metastases developed shortly thereafter. The differential diagnosis of primary and metastatic bronchial malignant melanoma is discussed. Other isolated case reports are reviewed.

Percutaneous chemical lumbar sympathectomy with alcohol with computed tomography control.

Percutaneous chemical lumbar sympathectomy with alcohol (PCLSA) using computed tomography (CT) control was performed in 8 patients suffering from advanced peripheral arterial occlusive disease. PCLSA under CT guidance was found to be a simple and safe procedure. The use of CT control added precision in the guidance of needle placement. Positive results were obtained in all patients, without significant morbidity. PCLSA may be an alternative to surgical sympathectomy.
