Abstract
BACKGROUND/OBJECTIVE The aim of this study was to identify the mammographic findings associated with malignancy in different age groups, taking into account breast composition (BC) and lesion size. METHODS Preoperative mammograms of 1023 invasive ductal carcinomas were retrospectively evaluated. According to the American College of Radiology Breast Imaging Reporting and Data System, cancer mammographic findings were classified as mass, calcifications, architectural distortion and asymmetry, and breasts were assessed as non-dense (A or B BC) and dense (C or D BC). Patient cohort was subdivided into three age groups (group 1: <50 years of age; group 2: between 50 and 69; group 3: ≥70 years of age). RESULTS Significant results of multinomial logistic regression were the association between mass and non-dense breast (p < 0.0001) and the association between mass and tumor size larger than 15 mm (p = 0.0049). CONCLUSIONS Mass finding of invasive ductal breast carcinoma is associated with breast composition and tumor size.

Abstract
PURPOSE To evaluate the efficacy of endovascular treatment for vascular renal injuries (VRIs) like bleeding, pseudoaneurysm and artero-venous fistula (AVF) and to compare patients with blunt trauma (T-VRIs) with those with iatrogenic damage (I-VRIs). METHODS We retrospectively assessed 49 renal artery embolizations performed to treat T-VRIs (26.5%) and I-VRIs (73.5%). Different embolic materials were used based on the type of lesion. Technical success was defined as the complete occlusion of target arteries with no further visualization of VRIs. Clinical success was defined if no recurrence was present and if renal function (difference between creatinine after and before treatment <0.5 mg/dl) was preserved after 1 month. RESULTS Angiography showed bleeding in 27 patients, pseudoaneurysm in 29 and an AVF in 6. Embolic agents used were coils in 39 procedures, coils with sponge in four and others in six. Technical success was 100% while clinical success was 85.7% due to seven patients with recurrence. The group I-VRIs showed a higher rate of clinical success than the group T-VRIs (94.4% vs 61.5%; p < 0.05). Moreover, the group I-VRIs had a higher incidence of pseudoaneurysms and AVFs compared with the group T-VRIs (69.4% vs 30.8% and 16.7% vs 0%; p < 0.05). CONCLUSION Endovascular treatment for VRIs showed satisfactory results and no patient had a worsening of renal function. I-VRIs had better clinical success and more frequently appeared as pseudoaneurysms compared to T-VRIs: probably iatrogenic injury is localized and pseudoaneurysm is easily identifiable and treatable with endovascular treatment.

Abstract
Tubulocystic renal cell carcinoma is a rare subtype of renal tumor according to the 2016 World Health Organization, and less than 100 cases have been documented up to date in literature. The imaging features are not well known and to the best of our knowledge, there is not a radiology description of recurrence from tubulocystic renal cell carcinoma in the literature. We describe the case of a 70-year-old man with unusual cystic lesions in the left hypochondrium 11 years after a nephrectomy for tubulocystic renal cell carcinoma on the same side, and we report a review of the clinical characteristics of metastatic tubulocystic renal cell carcinoma.

Abstract
AIM Recently the NOTES approach has been extended to mediastinum by a transesophageal access and to the thorax by a transvescical endoscopic approach. The aim of this study was to assess the feasibility and the safety of transgastric endoscopic approach to the thoracic cavity, with lung biopsy, in a survival porcine model. METHODS The study was performed on four 20-30 kg female pigs (Sus scrofus domesticus). Following gastric wall incision, the muscular pars of the left diaphragmatic dome was incised along with the parietal pleura and the endoscope advanced into the thoracic cavity. In all animals, a thoracoscopy was performed as well as peripheral lung biopsy. At the end of the operation the endoscope was withdrawn from the thoracic cavity after pleural sac decompression and the diaphragmatic incision closed by endoscopic clips under maximal expansion of lungs. The gastric incision was finally closed by endoscopic clips. Chest-tube placement was not utilized. Animals were sacrificed by day 15 postoperatively. RESULTS The gastroscope was easily introduced into the thoracic cavity that allowed to visualize the pleural cavity and to perform simple surgical procedures such as lung biopsies without complications. There were neither respiratory distress episodes nor surgical complications to report. No adverse event occurred during the survival period. The postmortem examination 15 days after surgery revealed a good closure of the diaphragmatic incision. At necropsy, the lung biopsies were completely healed. There were no signs of infection in both thoracic and peritoneal cavities. The length of follow-up and number of animals studied might have not been sufficient. CONCLUSION This study demonstrates the feasibility of transgastric thoracoscopy in porcine model. Long-term follow-up of much larger series will be necessary for provision of more reliable answers if this approach should be adopted in the future and eventually translated for humans with advantages for patients.

Abstract
AIM Natural orifice transluminal endoscopic surgery (NOTES) is a new reality that is progressively gaining popularity in the scientific community. The aim of this study was to report the authors' experience with various peroral transgastric procedures performed on the porcine model. The technical difficulties and challenges that arose were also analyzed. METHODS Ten anesthetized pigs, divided into an acute (3) and a survival group (7) underwent the following procedures using a double channel endoscope: peritoneoscopy (10), cholecystectomy (6),splenectomy (3), and gastrojejunostomy (3). RESULTS All the procedures were completed successfully. There was one complication related to the gastric wall incision. In the survival experiment group all pigs (4) submitted to biliare procedures made an uncomplicated recovery after a follow-up period of 2 weeks. Gastrojejunostomies (3) were instead graved by one technical failure (anastomosis disruption at post-mortem examination) and one case of mortality (premature euthanasia for evidences of sepsis). Complete gastric cleansing was impossible to achieve and overinflation was a common problem. The creation of gastro-enteric anastomoses was technically difficult with the current available devices. CONCLUSION Transgastric endoscopic surgery is technically feasible in a porcine model. A new instrumentation is needed and could strongly help to overcome the technical difficulties highlighted. More extensive animal studies are mandatory in order to evaluate the benefits and the limitations of this new technique.

Abstract
A 58-year old man was admitted to the hospital because of melena. He had a 1-year history of mechanical aortic valve replacement and coronary stent placement because of myocardial infarction and he was taking warfarin and clopidogrel. Esophagogastroduodenoscopy and colonoscopy were negative for bleeding. Capsule endoscopy showed bleeding diffuse angiodysplasia of the small bowel. The patient was treated with octreotide 20 mg, at monthly interval. After 25 months there had been no recurrence of gastrointestinal bleeding. The case suggests that mechanical valve replacement may not prevent gastrointestinal bleeding in Heyde syndrome and that octreotide treatment should be considered in these cases.

Abstract
The present study was performed to evaluate the long-term behavioral effect in offspring of a subteratogenic Cd dose administered by the oral route to Wistar rat during organogenesis. First, the teratogenic Cd dose was determined by treating pregnant rats with 20 mg/kg Cd from Day 6 to Day 14 of pregnancy and by visceral and skeletal analysis of their fetuses. In a second experiment, pregnant rats treated with this Cd dose were allowed to give birth and nurture their offspring. The physical and behavioral parameters of the offspring were analyzed in infancy and during adulthood. Results showed that Cd treatment during organogenesis (1) was not able to induce maternal toxicity; (2) induced external malformations; (3) increased significantly fetus anomalies and malformations, with reduced metacarpus ossification, cleft palate and right or left renal cavitation being observed in these animals; (4) did not modify pup body weight or weight gain during the lactation period; (5) improved testis descent and delayed the vaginal opening of pups; (6) did not modify ear unfolding, incisor eruption, eye opening, negative geotaxis or palmar grasp; (7) did not modify the open-field parameters and the stereotyped behavior of male or female pups; and (8) modified male sexual behavior and (9) reduced female sexual behavior.

Abstract
To investigate the role of the HIV-1 phenotype in mother-to-child HIV-1 transmission, we evaluated coreceptor usage and replication kinetics in chemokine receptor-expressing U87MG.CD4 cells of primary isolates from 32 HIV-1-infected mothers of Italian origin, none under preventive antiretroviral therapy, and from their infected infants. Five of 15 mothers of infected children and 2 of 17 mothers of uninfected children harbored viruses able to use CXCR4 as coreceptor. However, all isolates used CCR5, alone or in association with CXCR4. The replicative capacity in coreceptor-expressing cells of the viral isolates did not differ between the two groups of mothers. All mothers with an R5 virus transmitted a virus with the same coreceptor usage, whereas those four with a multitropic virus transmitted such a virus in one case. Although the presence of a mixed viral population was documented in the mothers, we did not observe transmission solely of X4 viruses. Interestingly, the only child infected with a multitropic virus carried a defective CCR5 allele. Analysis of the env V3 region of the provirus from this child revealed infection with multiple viral variants with a predominance of R5-type over X4-type sequences. These findings show that CCR5 usage of a viral isolate is not a discriminating risk factor for vertical transmission. Furthermore, X4 viruses can be transmitted to the newborn, although less frequently. In particular, we document the transmission of multiple viral variants with different coreceptor usage in a Delta32 CCR5 heterozygous child, and demonstrate that the heterozygous genotype per se does not contribute to the restriction of R5-type virus spread.

Abstract
We developed a recombinant virus technique to determine the coreceptor usage of human immunodeficiency virus type 1 (HIV-1) from plasma samples, the source expected to represent the most actively replicating virus population in infected subjects. This method is not subject to selective bias associated with virus isolation in culture, a step required for conventional tropism determination procedures. The addition of a simple subcloning step allowed semiquantitative evaluation of virus populations with a different coreceptor (CCR5 or CXCR4) usage specificity present in each plasma sample. This procedure detected mixtures of CCR5- and CXCR4-exclusive virus populations as well as dualtropic viral variants, in variable proportions. Sequence analysis of dualtropic clones indicated that changes in the V3 loop are necessary for the use of CXCR4 as a coreceptor, but the overall context of the V1-V3 region is important to preserve the capacity to use CCR5. This convenient technique can greatly assist the study of virus evolution and compartmentalization in infected individuals.

Abstract
BACKGROUND A deletion of 32 base pairs in the CCR5 gene (delta32 CCR5) has been linked to resistance to HIV-1 infection in exposed adults and to the delay of disease progression in infected adults. MATERIALS AND METHODS To determine the role of delta32 CCR5 in disease progression of HIV-1 infected children born to seropositive mothers, we studied a polymerase chain reaction in 301 HIV-1 infected, 262 HIV-1 exposed-uninfected and 47 HIV-1 unexposed-uninfected children of Spanish and Italian origin. Infected children were further divided into two groups according to their rate of HIV-1 disease progression: rapid progressors who developed severe clinical and/or immunological conditions within the second year of life, and delayed progressors with any other evolution of disease. Among the latter were the long-term, non-progressors (LTNP) who presented with mild or no symptoms of HIV-1 infection above 8 years of age. Viral phenotype was studied for 45 delayed progressors. RESULTS No correlation was found between delta32 CCR5 and mother-to-child transmission of HIV-1. However, the frequency of the deletion was substantially higher in LTNP, compared with delayed (p = 0.019) and rapid progressors (p = 0.0003). In children carrying the delta32 CCRS mutation, the presence of MT-2 tropic virus isolate was associated with a severe immune suppression (p = 0.028); whereas, the presence of MT-2 negative viruses correlated with LTNP (p = 0.010). CONCLUSIONS Given the rapidity and simplicity of the assay, the delta32 CCR5 mutation may be a useful predictive marker to identify children with delayed disease progression who, consequently, may not require immediate antiretroviral treatment.

Abstract
The aim of the present study was to compare the cumulative cost of the first 18-month period in a selected group of Italian cirrhotic patients treated with transjugular intrahepatic portosystemic shunt (TIPS) versus endoscopic sclerotherapy (ES) to prevent variceal rebleeding. Thirty-eight patients enrolled in a controlled trial were considered (18 TIPS and 20 sclerotherapy). The number of days spent in the hospital for the initial treatment and during the follow-up period were defined as the costs of hospitalization. ES sessions, TIPS procedures, angioplasty or addition of a second stent to maintain the shunt patency, were defined as the costs of therapeutic procedures. The two groups were comparable for age, sex, and Child-Pugh score. During the observation period 4 patients died in the TIPS group, and 2 died and 1 was transplanted in the sclerotherapy group. The rebleeding rate was significantly higher in the sclerotherapy group. Despite this, the number of days spent in the hospital was similar in the two groups. This was because of a higher number of hospital admissions for the treatment of hepatic encephalopathy and shunt insufficiency in the TIPS group. The therapeutic procedures were more expensive for TIPS. Consequently, the cumulative cost was higher for patients treated with TIPS than for those treated with sclerotherapy. The extra cost was because of the initial higher cost of the procedure and the difference was still maintained at the end of the 18-month follow-up. When the cumulative costs were expressed per month free of rebleeding, the disadvantage of TIPS disappeared. In conclusion, a program of prevention of variceal rebleeding with TIPS, despite the longer interval free of rebleeding, is not a cost-saving strategy in comparison with sclerotherapy.

Abstract
An unusual case of human immunodeficiency virus type 1 (HIV-1) infection in a child was studied. The child, identified as HIV-1 infected at 5 years of age, lived with his parents and a 3-year-old sister. HIV-1 infection was excluded in the mother and sister, but confirmed in the father, who was unaware of his infection and was in good health, apart from an atopic dermatitis on the face and limbs. A portion of the HIV-1 proviral envelope gene was amplified from the father's and child's peripheral blood cells, and the amplified products were cloned and sequenced. Phylogenetic analysis disclosed that the father's and child's viral sequences clustered together, and were clearly distinct from the sequence sets obtained from six epidemiologically unlinked mother-child HIV-1-infected pairs included in the analysis. HIV-1 variability was lower in the child's sequence set than in the father's, and the variability between father's and child's sequences was significantly lower than that found between epidemiologically unlinked cases (p < 0.001). An uncommon APGR motif on the tip of the V3 domain was found in both the father's and child's viral clones. These data, together with the epidemiological investigations, strongly suggest that the child acquired the infection from his father, possibly by exposure to bleeding skin lesions.

Abstract
Transjugular intrahepatic portosystemic shunt (TIPS), a new technique for the treatment of portal hypertension, has been successful in preliminary studies to treat acute variceal hemorrhage and to prevent variceal rebleeding. The purpose of this multicenter, randomized controlled trial is to compare the efficacy of TIPS with that of endoscopic sclerotherapy in the prevention of variceal rebleeding in cirrhosis. Eighty-one cirrhotic patients, with endoscopically proven variceal bleeding, were randomized to either TIPS (38 patients) or endoscopic sclerotherapy (43 patients). Randomization was stratified according to the following: if bleeding occurred < 1 week (stratum I); if bleeding occurred 1 to 6 weeks (stratum II); and if bleeding occurred 6 weeks to 6 months (stratum III) before enrollment. Follow-up included clinical, biochemical, Doppler Ultrasound, and endoscopic examinations every 6 months. During a mean follow-up of 17.7 months, 51% of the patients treated with sclerotherapy and 24% of those treated with TIPS rebled (P = .011). Mortality was 19% in sclerotherapy patients and 24% in TIPS patients (P = .50). Hepatic encephalopathy (HE) developed in 26% and 55%, respectively (P = .006). A separate analysis of the three strata showed that TIPS was significantly more effective than sclerotherapy (P = .026) in preventing rebleeding only in stratum I patients. TIPS is significantly better than sclerotherapy in preventing rebleeding only when it is performed shortly after a variceal bleed; however, TIPS does not improve survival and is associated with a significantly higher incidence of HE. The overall performance of TIPS does not seem to justify the adoption of this technique as a first-choice treatment to prevent rebleeding from esophageal varices in cirrhotic patients.

Abstract
We addressed the relationship between the origin and evolution of human immunodeficiency virus type 1 (HIV-1) variants and disease outcome in perinatally infected infants by studying the V3 regions of viral variants in samples obtained from five transmitting mothers at delivery and obtained sequentially over the first year of life from their infected infants, two of whom (rapid progressors) rapidly progressed to having AIDS. Phylogenetic analyses disclosed that the V3 sequences from each mother-infant pair clustered together and were clearly distinct from those of the other pairs. Within each pair, the child's sequences formed a monophyletic group, indicating that a single variant initiated the infection in both rapid and slow progressors. Plasma HIV-1 RNA levels increased in all five infants during their first months of life and then declined within the first semester of life only in the three slow progressors. V3 variability increased over time in all infants, but no differences in the pattern of V3 evolution in terms of potential viral phenotype were observed. The numbers of synonymous and nonsynonymous substitutions varied during the first semester of life regardless of viral load, CD4+-cell count, and disease progression. Conversely, during the second semester of life the rate of nonsynonymous substitutions was higher than that of synonymous substitutions in the slow progressors but not in the rapid progressors, thus suggesting a stronger host selective pressure in the former. In view of the proposal that V3 genetic evolution is driven mainly by host immune constraints, these findings suggest that while the immune response to V3 might contribute to regulating viral levels after the first semester of life, it is unlikely to play a determinant role in the initial viral decline soon after birth.

Abstract
Human immunodeficiency virus type 1 (HIV-1) can readily accept envelope (Env) glycoproteins from distantly related retroviruses. However, we previously showed that the HIV-1 Env glycoprotein complex is excluded even from particles formed by the Gag proteins of another lentivirus, visna virus, unless the matrix domain of the visna virus Gag polyprotein is replaced by that of HIV-1. We also showed that the integrity of the HIV-1 matrix domain is critical for the incorporation of wild-type HIV-1 Env protein but not for the incorporation of a truncated form which lacks the 144 C-terminal amino acids of the cytoplasmic domain of the transmembrane glycoprotein. We report here that the C-terminal truncation of the transmembrane glycoprotein also allows the efficient incorporation of HIV-1 Env proteins into viral particles formed by the Gag proteins of the widely divergent Moloney murine leukemia virus (Mo-MLV). Additionally, pseudotyping of a Mo-MLV-based vector with the truncated rather than the full-length HIV-1 Env allowed efficient transduction of human CD4+ cells. These results establish that Mo-MLV-based vectors can be used to target cells susceptible to infection by HIV-1.

Abstract
Forty-seven consecutive patients were prospectively evaluated to study the incidence of hepatic encephalopathy as well as modifications in the PSE index after TIPS. Various clinical, laboratory, and angiographic parameters were also recorded to identify risk factors for the development of post-TIPS hepatic encephalopathy (HE). Mean follow-up was 17 +/- 7 months. During follow-up, six patients died and one underwent transplantation. All other patients were followed for at least a year. Fifteen patients (32%) experienced 20 acute episodes of precipitated HE (hospitalization was necessary in 10 instances), and five patients (11%) presented a continuous alteration in mental status with frequent spontaneous exacerbation during follow-up. Both precipitated and spontaneous HE occurred more frequently during the first three months of follow-up. Moreover the PSE index was significantly worse than basal values one month after TIPS, thereafter returning to near basal values. HE was successfully treated in all patients but one who required a reduction in the stent/shunt diameter. Increasing age (>65 years) and low portacaval gradient (<10 mm Hg) were predictors of HE after TIPS. A gradual dilation of the stent/shunt should be performed to obtain a portacaval gradient >10 mm Hg to avoid an unacceptable rate of HE after TIPS.

Abstract
Variceal hemorrhage is a leading cause of death in patients with hepatic cirrhosis. We report the case of two cirrhotic patients with hepatocarcinoma in whom oesophageal varices bled repeatedly. Because the bleeding was not controlled by sclerotherapy, vasopressin or Blakemore balloon, the patients were evaluated for emergency transjugular intrahepatic portosystemic shunt. After the procedure, portal vein pressure decreased from 45.5 mmHg to 18 mmHg and from 44 mmHg to 19 mmHg respectively and no filling of varices was evident at venogram or endoscopy. After 16 and 8 months respectively, bleeding had not recurred, and no episodes of encephalopathy were referred. Transjugular intrahepatic portosystemic shunt should always be considered an effective emergency therapeutic alternative to shunt surgery in patients with active variceal bleeding when traditional management fails.

Abstract
Severe bleeding may complicate the course of either acute or chronic pancreatitis, the latter being more frequently involved. Pseudocysts, severe inflammation, regional necrosis and infection may cause major vessel erosion with or without pseudoaneurysm formation which eventually may result in severe bleeding into the gastrointestinal tract, retroperitoneum and peritoneal cavity. The AA report their experience on 8 cases and analyze the data of a comprehensive review of 389 cases of massive bleeding reported in the literature during the last 100 years until December 1993. Mortality rate seems to be related to the etiology of the bleeding along with its localization and the underlying anatomo-pathologic findings. In patients with chronic pancreatitis it is 22% while in patients with acute pancreatitis or chronic pancreatitis with acute exacerbation it is 60.4% and 57.1% respectively. Splenic, gastroduodenal and superior pancreaticoduodenal arteries are the most commonly involved vessels being associated respectively with a mortality rate of 20.5%, 27.9% and 46.1%. Massive haemorrhage complicating infected necrosis or abscesses implies a worse prognosis when compared to severe bleeding associated with pseudocyst with or without pseudoaneurysm. The increasing use of diagnostic and interventional radiology appears to be the way forward to improve survival rates. Awareness of high risk predisposing condition, activism in achieving an early identification of the bleeding sources, and eventually its angiographic control are essential guidelines for successful approach to the most unpredictable complication of pancreatitis. When embolization fails or is followed by recurrence of hemorrhage, definitive surgical procedures should be immediately instituted.

Abstract
The third variable region (V3) of the envelope protein of human immunodeficiency virus type 1 (HIV-1) contains group- and type-specific epitopes for neutralizing antibodies and contains determinants involved in viral tropism and syncytium-inducing (SI) activity. We studied the in vivo relationship between V3 sequences and viral phenotypes in 24 perinatally HIV-1-infected children. To avoid in vitro selection of intrapatient minor variants, genetic studies were performed directly on uncultured peripheral blood mononuclear cells (PBMC), and the tropisms of HIV-1 isolates were evaluated by culturing patients' PBMC directly with monocyte-derived macrophages, lymphocytes, and MT-2 cells. According to their phenotypes, we could define five types of primary isolates: (i) non-syncytium-inducing (NSI) macrophagetropic, (ii) NSI macrophage-lymphotropic, (iii) NSI lymphotropic, (iv) SI lympho-T-cell line-tropic, and (v) SI pleiotropic. The SI viral phenotype was correlated with a more advanced status of disease. Genetic analysis of intrapatient molecular variants revealed that no relationship between the degree of intrapatient V3 variability and the pattern of viral tropism existed; moreover, within a single patient, the values for V3 variability between CD4+ lymphocytes and CD14+ monocytes were similar, thus suggesting that in vivo variability of the monocytotropic variants is more extensive than previously appreciated. A comparison between the intrapatient major variants and the phenotype of primary isolates disclosed that a negatively charged amino acid at residue site 25 was associated with an NSI macrophage- and macrophage-lymphotropic viral phenotype. Finally, by comparing the V3 sequences derived from our study population with those of several prototypes, we observed that the majority of isolates circulating in Italy are related to the North American subtype B macrophagetropic isolates.

Abstract
The authors report a case of massive intestinal hemorrhage caused by rupture of a splenic artery pseudoaneurysm into a pseudocystojejunostomy. The pathologic and clinical features of this unusual complication of pancreatitis are discussed. One hundred and seventy one cases of major bleeding associated with pseudocysts and/or pseudoaneurysms have been reported in the literature during the period 1989-May 1991. Acute and chronic pancreatitis may be the underlying etiologies and the overall mortality rate of this complication is 35.1%. According to the authors experience, angiographic localization of the bleeding sources and steel coil embolization play a key role in the diagnostic and therapeutic approach to what is generally regarded as the most rapidly lethal sequelae of pancreatitis.

Abstract
Polymerase chain reaction was performed in 251 infants born to HIV-1-seropositive mothers to diagnose HIV-1 infection. Assay specificity was invariably > 95%, regardless of age at testing, while sensitivity ranged from 15% in neonates (within 48 h of birth) to > 95% in infants over 1 month of age. Evaluation of viral burden in 43 infected infants by means of quantitative DNA-PCR disclosed that the number of HIV-1 proviruses ranged from 5 to 947 per 100,000 peripheral blood mononuclear cells. Clinical follow-up demonstrated that a high viral burden was associated significantly with disease onset.

Abstract
Fifteen patients with squamous cell carcinoma of the uterine cervix--7 in stage II, 6 in stage III and 2 in stage IV--were considered not to respond at the end of radiotherapy. Therefore, the whole patient population underwent bilateral intraarterial chemotherapy with Mitomycin-C (3 cycles, 3-4 weeks' intervals). Patients' responses were evaluated with clinical and CT examinations following irradiation and after completing chemotherapy. Pelvic irradiation was administered by external beams (6 Mv), for a 50-Gy dosage (200 cGy/day for 5 weeks); in 4 cases treatment was completed by means of brachytherapy (192 Ir), with 20-25 Gy dosage. Intraarterial infusion was carried out after positioning the catheters in both uterine arteries; in 5 cases, the internal iliac artery alone was cannulated. At the end of the combined treatment, 2 patients (13%) responded completely, 9 (60%) partially and 4 (27%) not at all. Mean survival was 24 months. No hematologic complication was so severe that treatment had to be discontinued. In 4 patients chemotherapy caused a partially ulcerated skin erythema in the buttocks, which was completely cured in all cases.

Abstract
Transluminal angioplasty represents an alternative to operation in treatment of arteriosclerotic stenosing and obstructive lesions. The authors report their experience since 1973 with 64 cases treated in the iliac, femoral or popliteal region and 2 cases of stenosis of the renal artery. Arterial tract may be dilated or recanalized depending on stage of the lesion. Patient's follow up with angiography and flow controls showed 70% of success for dilatation and 60% for recanalization at 5 and 4 years respectively. The rate of success and low incidence of complications are particularly encouraging and suggest this type of treatment not only for inoperable high risk patients but also as an elective procedure in well selected patients. Moreover technical facilities and skill of the operator may extend the applicability of angioplasty to treatment of other stenosed segments at the level of renal, coronary and visceral arteries and of iliac veins.
