Angioradiology

The diagnosis of pseudoaneurysm of the deep femoral artery as a late complication after orthopaedic surgery is uncommon. The causes of the injury of the artery may be due to the intervention technique itself (mainly the orthopaedic materials or the use of clips), and less frequently by fragments displaced by the trochanter. A case of pseudoaneurysm of the deep femoral artery by a less displaced trochanter fragment is presented in this article, showing how the different professionals interacted, and with the intervention of specialists in angioradiology to resolve it...

The microsurgical failure rate is almost constant for several decades. We present two case reports describing a novel method of free flap salvage using angioradiological techniques. Our first case shows the potential utility of in situ thrombolysis, our second case describes the first use of stents within a microsurgical anastomosis. In boths cases, the flap would have been lost immediately, because flap revisions failed. Thus, before abandoning on a flap, one could perform a simple angiography to evaluate further angioradiological salvage possibilities and hereby contribute to improve long term microsurgical failure rate...

INTRODUCTION: Facial arteriovenous malformations (AVMs) are quite rare morbid conditions that clinically present themselves mainly as a massive bleeding or a significant aesthetic defect. Vascular malformations do not regress spontaneously; this is the reason why their resection is necessary. The successful treatment of these vascular anomalies is often compromised, since a high incidence of recurrence could be expected if the lesion is not managed properly. A multidisciplinary approach is needed for the assessment and treatment of these lesions...

AIM: Arteriovenous malformations (AVMs) with a high flow of the head and neck are quite rare compared to their low-flow counterparts, but when they do occur they are often accompanied by massive bleeding or present with significant esthetic defects. The treatment of these high-flow vascular anomalies is often highly risky. The multidisciplinary approach required for the assessment and treatment of these lesions should include angioradiology with preoperative superselective embolization, followed by surgical resection of the lesion within 24 hours and esthetic reconstruction...

A non cirrhotic patient with esophageal varices and portal vein thrombosis had recurrent variceal bleeding unsuccessfully controlled by endoscopy and esophageal transection. Emergency transhepatic portography confirmed the thrombosed right branch of the portal vein, while the left branch appeared angulated, shifted and stenotic. A stent was successfully implanted into the left branch and the collateral vessels along the epatoduodenal ligament disappeared. In patients with esophageal variceal hemorrhage and portal thrombosis if endoscopy fails, emergency esophageal transection or nonselective portocaval shunting are indicated...

The case of a 59 year-old patient, who sustained a post-traumatic fracture of the silastic catheter of his totally implantable venous access device that migrated in the right pulmonary artery, is reported. The venous device was placed six months earlier for the treatment of metastatic spread of a primary unknown adenocarcinoma. The venous device was placed on the left side in consideration of a recent right supraclavicular node biopsy. The catheter was introduced through the left internal jugular vein and its peripheral end was positioned subcutaneously across the clavicle to be connected to the port chamber placed in the infraclavicular region...

High flow priapism is an infrequent entity, generally following traumatic injuries in the genito-perineal area. Anamnesis, cavernous bodies blood gasometry and Doppler are the basic diagnostic tools for these condition. Therapeutical management is considerably different from that used for low flow venous priapism. Selective arteriography of the internal pudendal artery allows to locate the arterial lesion and, at the same time, to perform supraselective embolization of the lacerated cavernous artery which is currently considered the choice treatment...

OBJECTIVE: To evaluate the use of percutaneous transluminal renal angioplasty (PTRA) in the treatment of renal vascular hypertension. DESIGN: Sequential prospective PTRA treatment of severe arterial hypertension, screening by the captopril test, confirmed by renal arteriography, and the result evaluated by post-PTRA arteriography, blood pressure measurement and renal function. SITE: Vascular Surgery, angioradiology sector, and Nephrology outpatients department of the Federal University of São Paulo-Paulista School of Medicine, São Paulo, Brazil, a tertiary health-care institution...

The number of geriatric patients has increased in the last decade, as shown in diagnostic angiography and angioplasty. Therefore, the radiologist must be prepared for technical problems. Elderly patients need special premedication, care and also more time for each diagnostic and interventional procedure. In these patients, in several situations DSA can be done more efficiently as an inpatient procedure and not on an outpatient situation. Angioplasty of iliac and femoropopliteal injuries in this population is not only a means of treating claudicatio without high risk, but of also preventing amputation of the leg...

In this study we investigated the efficacy of percutaneous transluminal angioplasty (PTA) and laser percutaneous transluminal angioplasty (LPTA) as an adjunct to surgery in patients with peripheral vascular disease. We report 84 cases of the simultaneous association of direct arterial surgery and angioradiological procedures to treat 82 patients with arterial occlusive disease of the lower limbs. Sixty-five patients (79.2%) were affected by severe claudication and 14 (19.6%) presented with rest pain or gangrene...

Authors present their experiences during 10 years (1980-89) with the treatment of peripheral arteriopathies with the ATP. Between a total of 455 procedures, an accumulative permeability of 82% in the iliac sector and 71% in the femoro-popliteal sector in elective indications was reached. The total availability of this therapeutic method, the accurate selection of indications and the valious cooperation between Angioradiology and Vascular Surgery Departments should be noted.
