[Epidural venography in the diagnosis of lumbar disease (author's transl)].
80 patients with back pain and sciatalgia were studied by plain-film of lumbosacral spine, radiculography and epidural phlebography; 30 of them were surgically controlled. Radiculographic and phlebographic specimens were compared and phlebography showed more sensibility and specificity in the study of extradural pathology. The analysis of the phlebographic alterations suggested a semeiologic criterion we think that could be usefully used in the study of osteoligamentous lesions in lumbosacral spine.

Percutaneous treatment of iliac aneurysms and pseudoaneurysms with Cragg Endopro System 1 stent-grafts.
PURPOSE: To evaluate the feasibility and short-term follow-up results of treating iliac aneurysms by the Cragg Endopro System 1 stent-graft. METHODS: Nine lesions (two pseudoaneurysms and seven atherosclerotic aneurysms) were treated in eight patients by percutaneous implantation of a total of 10 stent-grafts. The procedure was followed by anticoagulation with heparin for 6 days, then antiplatelet therapy. Follow-up was by color Doppler ultrasound scan at 2 days and 3 months after the procedure for all patients, and by venous digital subtraction angiography and/or angio-CT up to 12 months later for four patients. RESULTS: Initial clinical success rate was 100% and there were two minor complications. In one case the delivery system was faulty resulting in failure to deploy the stent-graft. An additional device had to be used. At 3-12 months all prostheses were patent but one patient (12.5%) had a minimal pergraft leak. CONCLUSION: Percutaneous stent-grafting with this device is a safe and efficacious treatment of iliac artery aneurysms.

Anatomy of the iliolumbar ligament: a review of its anatomy and a magnetic resonance study.
Data of the postmortem studies of the iliolumbar ligament are controversial because of the number, complexity, and variability of the structures present in the lumbosacral region. The objective of this work was to study the anatomy of the iliolumbar ligament to resolve some clinical problems: (1) do anatomic bases exist that can explain the lumbar painful syndrome termed "iliolumbar syndrome?" (2) do iliolumbar ligament varieties exist that can influence lumbosacral joint stability? Magnetic resonance was used to analyze the anatomic structure of the iliolumbar ligament of live human beings. Thirty iliolumbar ligaments of 15 volunteers were analyzed with magnetic resonance. The images were acquired along the transversal and coronal planes (respectively, superoinferior and anteroposterior). The portion of the iliolumbar ligament originating from the L-5 transverse process is made up of two bands (anterior and posterior). The anterior band is broad and flat and has two different anatomic varieties. Type 1 originates from the anterior aspect of the inferolateral portion of the L-5 transverse process and fans out widely before inserting on the anterior portion of the iliac tuberosity. Type 2 originates anteriorly, laterally, and posteriorly from inferolateral aspect of the L-5 transverse process and fans out before inserting on the anterior portion of the iliac tuberosity. The posterior band of the iliolumbar ligament originates from the apex of the L-5 transverse process and is fusiform. Just before inserting on the anterior margin and apex of the iliac crest it widens, assuming the aspect of a small cone. On the transaxial plane, the anterior band of the iliolumbar ligament was placed along the horizontal line passing through the transverse processes, whereas the posterior band formed an angle of approximately 45 to 55 degrees opened posterolaterally with this line. On the coronal plane, the spatial disposition of the iliolumbar ligament varies greatly with the size of the L-5 vertebra and its position in the pelvis: (1) when L-5 is situated low in the pelvis, the bands of the iliolumbar ligament are longer and oblique; (2) when L-5 is situated high in the pelvis, the bands of the iliolumbar ligament are shorter and horizontal. The insertion manner of iliolumbar ligament posterior band in the iliac crest allows us to confirm the possibility of existence of the lumbar painful syndrome termed iliolumbar syndrome and confirms the possibility of examining its insertional site manually. Being accessible manually, various drugs can be injected directly into it or deep friction can be applied. This posterior band is thinner than the anterior, with a smaller insertional base on the iliac crest, which explains its lesser resistance to torsional overloading and also explains the frequency of this painful syndrome. It is probable that the spatial disposition of the iliolumbar ligament influences its antitorsional role. Further anatomic and biomechanic studies are needed.

Plantar fat pad atrophy after corticosteroid injection for an interdigital neuroma: a case report.
A case of bilateral interdigital (Morton's) neuroma treated with steroid injection therapy developed plantar fat pad atrophy, shown on magnetic resonance imaging. Some pathologic changes at the site of injection (such as subcutaneous fat atrophy, depigmentation of the skin, and telangiectasias) are well known disadvantages of local steroid injection for the treatment of the Morton's neuroma. Scientific literature reports these problems (mainly as an aesthetic problem) in the dorsal aspect of the foot. In this work, the authors describe a case in which the steroid injection therapy has caused some changes in the plantar aspect of the feet, with serious functional problems. Fat pad atrophy is a serious problem in the foot and can cause a painful metatarsal syndrome with some important effects on the gait.

[Renal angioplasty in the treatment of renovascular hypertension. A comparison of results and the authors' own experience].
From 1986 to 1989, 68 patients with 79 stenoses (11 bilateral, 4 unilateral) underwent renal angioplasty in the Radiology Departments of Udine (34 cases) and Pisa (34 cases). Fifty-eight patients were arteriosclerotic (mean age 58) and 21 fibrodysplastic (mean age 32). The fibrodysplastic lesions were treated in Pisa. Recovery was obtained in 64/68 patients and 75/79 stenoses (residual stenosis less than 20%). Renovascular hypertension was cured or reduced in 57/64 cases. The angiographic follow-up (mean 15 months) of 54/75 stenoses demonstrated recurrence in 2/19 fibrodysplastic and in 6/35 arteriosclerotic lesions; 2 patients underwent angioplasty and 2 surgery: one patient per group exhibited no change in hypertension values. Thus, we believe that hypertension should be better defined (e.g. by selective reninemia sampling and Ace-inhibitor renal scintigraphy). The follow-up (mean 22 months) of hypertension in 48/64 patients (arteriosclerotic: fibrodysplastic = greater than 33/15) showed complete recovery in 8/33 and in 10/15 cases (24% and 66%, respectively); a significant improvement was obtained in 15/33 and in 2/15 cases (45% and 14%, respectively). Our results confirmed the higher efficacy of renal angioplasty in the treatment of fibrodysplastic lesions; as for arteriosclerotic lesions, angioplasty has been observed to improve vascularization rather than to cure hypertension.

A multicentric phase II clinical trial on intra-arterial hepatic radiotherapy with 90yttrium SIR-spheres in unresectable, colorectal liver metastases refractory to i.v. chemotherapy: preliminary results on toxicity and response rates.
BACKGROUND: In patients locally progressing after two lines of chemotherapy, some locoregional approaches showed encouraging results in terms of local control of disease. The aim of our study was to evaluate toxicity, clinical response and quality of life in 48 patients with unresectable colorectal liver metastases submitted to selective internal radiotherapy (SIRT). MATERIALS AND METHODS: Up to now 35 patients with unresectable colorectal liver metastases, refractory to two lines of chemotherapy, underwent intra-arterial infusion of resin microspheres with yttrium-90 (SIR-spheres). Pre-treatment evaluation included a CT scan, blood tests, a PET scan and arteriography of celiac trunk, hepatic and superior mesenteric artery; extrahepatic uptakes and pulmonary shunts more than 10% were excluded by a Scinti-scan. The gastroduodenal artery was embolized before the SIR-spheres injection. Other exclusion criteria were liver dysfunction and anatomical vascular anomalies. The clinical response was evaluated by CT-scan following the RECIST criteria. Median follow-up was 4 months. RESULTS: Median number of metastases was 4 (range, 1-15), 38% of cases presenting hepatic involvement < 25%. The median SIRT dose delivered was 1.7 GBq. Median pulmonary shunt was 6%. No operative mortality occurred; early toxicity (within 48 hours) was 20.6%, shown as fever, acute pain and leucocytosis. The late toxicity was 24.1% with chronic pain, jaundice and nausea being the most frequent. All the toxic events were graded 2 or 3 according to the WHO scale. Preliminary results were available in terms of clinical response after 6 weeks: 12.5% had a partial response, 75% a stable disease, while progression of disease, was observed in 12.5% of the patients. CONCLUSION: SIRT is a safe treatment in terms of acute and late toxicity. Intra-arterial microspheres could represent a good therapeutic option for patients with progressing liver metastases only, after two lines of systemic chemotherapy.

[Role of double contrast arthrography of the shoulder in the assessment of lesions of the rotatory muscle cuff].
From 1980 to 1989 the author performed 481 double-contrast arthrographic examinations of the shoulder (DCSA). A hundred and forty-two complete and 46 partial rotator cuff tears were demonstrated; 68 of them underwent surgical exploration. Our results confirmed DCSA capabilities in detecting rotator cuff tears (greater than 98%) and in defining both their location (100%) and size (95%). Moreover, thickness (89%) and erosions (94%) in tendon edges and surfaces were demonstrated--that is, all the qualitative information needed to depict degenerative processes. Such evidence may also affect treatment planning.
