Microfoam ultrasound-guided sclerotherapy treatment for varicose veins in a subgroup with diameters at the junction of 10 mm or greater compared with a subgroup of less than 10 mm.

OBJECTIVE: The objective was to analyze the effectiveness of foam ultrasound-guided sclerotherapy treatment in saphenous veins and tributary veins with a diameter at the saphenofemoral or saphenopopliteal junction of > or =10 mm and compare these results with a subgroup of veins with diameters of < 10 mm. METHODS: A subgroup of 17 saphenous veins with a diameter at the saphenofemoral or saphenopopliteal junction of > or =10 mm were compared with a subgroup of 98 saphenous veins with a diameter of < 10 mm at the saphenofemoral or saphenopopliteal junction for clinical efficacy and patient satisfaction at a mean 2-year follow-up. RESULTS: A mean number of 2.15 treatments utilizing an average of 8.37 mL of foam sclerosing solution (3% sodium tetradecyl sulfate) were required to close all incompetent varicose veins in the < 10-mm group versus a mean of 2.8 treatments and 13.9 mL foam (3% sodium tetradecyl sulfate) for the > or =10-mm group. A total of 27.5% of saphenous veins of < 10 mm and 37.5% of saphenous veins > or = 10 mm required a second treatment at 3 months. One-hundred percent of patients believed that their legs were successfully treated at 2-year follow-up in both groups with 94% of the < 10-mm group noting improvements in quality of life and 100% in the > or =10-mm group. CONCLUSIONS: Ultrasound-guided foam sclerotherapy is effective in treating all sizes of varicose veins with high patient satisfaction and improvement in quality of life. Duplex ultrasound findings demonstrated a small increase in failure to close the saphenofemoral or saphenopopliteal junction with increasing size of junction diameter, but this does not significantly alter the results with respect to clearance of visible varicosities and patient satisfaction with results.

Allergic reactions to polidocanol for vein sclerosis. Two case reports.

BACKGROUND: Polidocanol is a sclerosing solution that is highly valued by clinicians and patients for its painlessness, high efficacy, excellent safety profile, low incidence of side effects, and for the rarity of its allergic reactions. Previous estimates of the incidence of allergic reactions have ranged from 0 to 0.06%. OBJECTIVE: Improved recognition of systemic allergy to polidocanol is desirable for both clinicians and for patients. We have attempted to describe two cases recently observed in our population and to provide an improved upper-bounds estimate for the true population incidence of allergy to polidocanol. RESULTS: We report two recent cases of mild systemic allergic reaction to polidocanol in a population of 689 exposed patients, for an observed incidence of 0.3% in our patient population. We have calculated a 95% confidence upper-bound estimate of 0.91% for the incidence of polidocanol allergy in the general population. CONCLUSION: Allergy to polidocanol may be more common than previously recognized. Careful questioning of previously treated patients and more prolonged observation of patients after treatment may yield a larger number of recognized cases.

Color duplex-guided sclerotherapy for the treatment of venous malformations.

BACKGROUND: Although surgical extirpation is the standard method for the treatment of vascular malformations, this procedure often leads to loss of motor function, nerve damage, and massive bleeding if the excision is extensive. Sclerotherapy is an alternative method of treatment for venous malformations. OBJECTIVE: This study was conducted to assess the effect of color duplex ultrasound-guided sclerotherapy on venous malformations and the coagulability induced by sclerosing solution. METHODS: Twenty-eight patients with venous malformations underwent percutaneous sclerotherapy by direct puncture under duplex ultrasound guidance. Intravenous catheters were inserted into duplex ultrasound-confirmed venous spaces and fine plastic tubing filled with normal saline was attached to the needle. When the needle tip was observed to pierce the vein wall, aspiration of the blood confirmed its intraluminal position. The mean volume of 3.6 ml of 3% polidocanol was injected. Subfascial ligation of the lateral marginal venous collector was performed in patients with Klippel-Trenaunay syndrome. D-dimer (DD) and thrombin-antithrombin III (TAT) were measured preoperatively and on the first and fifth postoperative days. RESULTS: The head and neck, which was the most common site of venous malformations were involved in 57% of the patients. Venous malformations disappeared in 44% of the patients and decreased in 28%. Localized pain was the most common complication, occuring in 82% of the patients. Sclerotherapy for venous malformations produced significant swelling in 75% of the patients, which required 5-7 days to subside. Significant differences were detected in both DD and TAT concentrations on the first and fifth postoperative days. CONCLUSIONS: Color duplex-guided sclerotherapy was effective in 82% of the patients. This procedure prevents intra-arterial injection accidents. Although patients with venous malformations showed greater coagulability, no serious thrombotic sequelae were found.

Tetracycline sclerotherapy for testicular hydroceles in renal transplant recipients.

OBJECTIVES: To study the efficacy of tetracycline sclerotherapy in renal transplant recipients with symptomatic hydroceles. METHODS: A total of 21 patients with symptomatic hydroceles following renal transplantation underwent aspiration of hydrocele and injection of tetracycline hydrochloride. Sclerosant solution was prepared by dissolving 1 g tetracycline hydrochloride powder in 10 mL 1% lidocaine. The amount of sclerosant used depended on the volume of the sac: 5 mL for a sac containing up to 100 mL and 2.5 mL of sclerosant was added for each increase of 100 mL in sac volume. RESULTS: Twelve patients (57%) required only one treatment and 9 patients (43%) had up to 3 injections. The larger the hydrocele, the more treatments were required. The resolution of hydrocele was complete in 12 patients (57%) and partial in 7 (33%) with 2 (10%) failures. Pain at injection was observed in one third of the patients. No major complications (fever, hematoma, infections, abscess, or scrotal necrosis) occurred in any patient. No changes in the structure or size of the testicles were found by ultrasound during an average follow-up period of 35 months. CONCLUSIONS: Tetracycline sclerotherapy is a safe, effective, and economical form of out-patient therapy that can be recommended as primary treatment for hydroceles in patients who have undergone renal transplantation.

Scintigraphic detection of pulmonary embolization of esophageal variceal sclerosant.

Intravariceal injection of a sodium morrhuate sclerosant solution, an effective therapy for bleeding esophageal varices, is complicated occasionally by fever and pneumonia. To determine if embolization of sclerosant to or through the pulmonary circulation occurs, chest scintigrams were performed following intravariceal injection of 1-3 mCi 99m-Tc-MAA mixed with 5-20cc of sclerosant in 18 patients undergoing a total of 25 sclerotherapy sessions. Sclerosant embolization was documented in 15/25 procedures (60%). Tracer localization in esophageal veins cephalad to the injection site (gastroesophageal junction) occurred in 2 studies. Atelactasis, effusion, or infiltrate on chest x-ray occurred after 6/25 procedures. Post-sclerosis fever (greater than 99.5 degrees F) occurred in 5/15 (33%) with embolization and in 1/10 (10%) without. However, neither x-ray abnormalities nor fever were positively correlated with sclerosant embolization. We conclude that embolization of sclerosant to the pulmonary arterial circulation occurs frequently. Chest radiographs may be negative despite significant embolization.

Out-patient sclerotherapy of idiopathic left-sided varicocele in children and adults.

Between 1983 and 1989, 334 patients with idiopathic left-sided varicocele were referred for transfemoral sclerotherapy; 323 were adults and 11 were children. The standard site of injection of the sclerosing solution (Varicocid-Natriummorrhuat 55 mg, Benzylalkohol 20 mg) was the mid-portion of the spermatic vein. The upper third was injected only in cases where the catheter could not be negotiated further (e.g. abnormalities in the course of the spermatic vein or its drainage into the intrarenal veins). The amount of sclerosing material was predetermined fluoroscopically using contrast material. Occasionally, in cases of high catheter positioning, the Varicocid was injected fractionally. The amount injected was always between 1 and 3 ml. Of 80 patients studied 1 year later, varicoceles were still present in 3 (4%). The best results were achieved in patients with small varicoceles (Grade I), normal testicular volume and normal FSH levels; 29% showed an improvement in sperm count and 27% an increase in sperm motility, while sperm morphology improved in only 7%. The conception rate was 11%.

Injection sclerotherapy-induced esophageal strictures. Risk factors and prognosis.

Injection sclerotherapy (IS) has become an effective modality for the treatment of bleeding esophageal varices. Despite improvements in equipment, sclerosant solutions and operator technique, injection sclerotherapy-induced esophageal strictures (ISES) remain a significant cause of patient morbidity. To analyze the risk factors and prognosis of ISES, the records of 117 patients who underwent IS over a 6-year period at a single teaching institute were reviewed. The predictive value of multiple risk factors including the patient's age, Child's risk classification, previous bleeding episodes, etiology of varices, cumulative amount of sclerosant used, and the number of IS treatments were determined using ANOVA. A P value of less than 0.05 was considered significant. In all cases, a free-hand injection technique, flexible endoscopes and sodium morrhuate were used. During a mean follow-up period of 228 days (1-1,469 days), 41 patients (35%) died and 24 patients (20.5%) developed symptomatic strictures. The cumulative amount of sclerosant used (81.4 +/- 9.5 ml) and the number of IS treatments (6.5 +/- 0.7) required in the stricture group was significantly greater than in the nonstricture group (49.1 +/- 2.7 and 4.0 +/- 0.3, respectively). The risk of stricture formation did not correlate with the volume of sclerosant injected per treatment, cause of varices, number of previous bleeds, or Child's hepatic risk class. A mean of 3.6 +/- 4.5 dilations was required for treatment of established strictures and 18 patients (75%) required r 4 dilations. One esophageal perforation occurred following dilation. Mortality correlated with hepatic risk class as 30/41 (73%) of deaths occurred in Child's C patients.(ABSTRACT TRUNCATED AT 250 WORDS)

What are hemorrhoids and what is their relationship to the portal venous system?

New concepts of the pathophysiology of hemorrhoids have been defined during the past eight or more years, yet medical education at the undergraduate and graduate levels has not kept pace with the newer concepts. The traditional concepts are being perpetuated in all medical dictionaries and in most textbooks of surgery, medicine, anatomy, and pathology. Hemorrhoids are not varicosities, but rather are vascular cushions composed of arterioles, venules, and arteriolar-venular communications which slide down, become congested and enlarged, and bleed. The pathogenesis begins in the fibromuscular supporting layer in the submucosa, above the vascular cushions. The bright red bleeding, which accompanies hemorrhoidal disease, is arteriolar in origin. Portal hypertension has been shown not to be the cause of hemorrhoids. The use of rubber bands, sclerosing solutions, cryosurgery, or the infra-red beam in the early stages of hemorrhoidal disease can take care of prolapse and bleeding and can prevent the development of third and fourth degree hemorrhoids.

Sclerotherapy of hydroceles with polidocanol.

Fifteen patients with hydroceles of the testis or spermatic cord were treated by aspiration and injection of the sclerosant solution polidocanol. The cure rate of hydroceles after one sclerotherapy session was 73%, and the overall cure rate using the procedure was 87%. No patient experienced pain during or after the procedure, which was conducted without anaesthesia. No complications were observed. It is concluded that sclerotherapy of hydroceles with polidocanol may be a useful alternative to open operation, due to its ease of administration, low frequency of complications, and high rate of effectiveness, and that this agent is preferable to certain other drugs in that it causes no pain during or after the injection.

Prospective randomized comparison of esophageal variceal sclerotherapy agents: sodium tetradecyl sulfate versus sodium morrhuate.

We designed a prospective randomized study to evaluate differences in efficacy and complication rate between the two most commonly used sclerosing agents, sodium tetradecyl sulfate (STD) and sodium morrhuate (MOR). Of 41 patients with acute index variceal bleeding initially evaluated, 21 were randomized to receive 0.75% STD and 20 to receive 1.6% MOR diluted with 50% dextrose. Overall mortality for the STD group was 38% and that for the MOR group was 25% (NS). Control of acute bleeding was achieved in 86% of the STD patients and 90% of the MOR patients (NS). Overall, obliteration was achieved in only 33% of the STD group and 25% of the MOR group; but in those patients who remained in the study over 3 months, obliteration was achieved in 87 and 83%, respectively (NS). There was a trend toward higher rebleeding in the STD group compared with the MOR group (81% vs. 51%) (p = 0.078), but there was no significant difference between the STD and MOR patients with regard to transfusion requirements (8.4 units/patient vs. 8.7 units/patient), ulceration (53% vs. 40%), or stricture formation (9.5% vs. 0.0%). The results of this study suggest that STD and MOR are clinically equivalent sclerosing solutions, and that bias favoring use of one agent over the other may be unfounded.

Doppler ultrasound findings in reticular veins of the thigh subdermic lateral venous system and implications for sclerotherapy.

BACKGROUND: Treatment of varicose veins is directed towards eliminating sources of reflux causing venous hypertension in the superficial venous system. Doppler ultrasound is routinely used to localize sources of reflux prior to treatment of large varicose veins. OBJECTIVE: To assess the value of Doppler ultrasound in localizing reflux in subcutaneous reticular veins associated with groups of lateral thigh telangiectases. METHODS: Seven hundred patient records in which Doppler ultrasound was performed on thigh reticular veins were reviewed. Patients with reflux of the saphenofemoral junction, saphenopopliteal junction, or major saphenous system perforators were excluded. RESULTS: Audible reflux upon distal calf compression release was noted in thigh subcutaneous reticular veins of 618 out of 700 patients (88%). These incompetent reticular veins were associated with groups or webs of telangiectases and/or venulectases on the lateral thigh in almost all cases. Reflux was loudest just distal to the lateral femoral condyle. In 20 patients Doppler ultrasound was performed on a reticular vein while a telangiectasia associated with the reticular vein was injected with sclerosing solution. In 15 patients a clearly audible flow signal was heard in the reticular vein during injection. CONCLUSION: These findings indicate an association of telangiectatic veins with reticular veins on the thighs. Furthermore, this study underscores the value of Doppler in determining sources of reflux in smaller veins and implies that sclerotherapy of reticular veins is necessary for treatment of thigh telangiectatic webs.

An ambulatory treatment of varicose veins associating surgical section and sclerotherapy of large saphenous veins (3S technique). Preliminary study with results at one year.

BACKGROUND: The 3S technique enables treatment of large incontinent greater saphenous veins in patients who, for medical or social reasons, refuse traditional surgical methods. It associates phlebectomy with section-ligation and injection of a sclerosing solution in the proximal and distal segments. The 3S technique is merely one stage in the treatment of the saphenous vein, aimed at suppressing reflux, and associated with sclerosis of the junction. It must always be combined with later sclerotherapy sessions. METHODS: One hundred and eight patients were operated on by the 3S technique, of which 100 had 1-year follow-up. Each patient was checked by duplex scan examination before treatment, and 1 month and 1 year after. RESULTS: We obtained good results without reflux in 96% at the sapheno-femoral junction at 1 year. CONCLUSIONS: Superficial venous insufficiency is a chronic disease with evolution or recurrences. To appreciate the efficiency of 3S technique, it will be better to have 5 years worth of follow-up. This is a preliminary study with a short follow-up.

Sodium morrhuate delivery to the lung during endoscopic variceal sclerotherapy.

We determined quantitatively the amount of sodium morrhuate that reaches the pulmonary vascular bed during endoscopic variceal sclerotherapy to ascertain whether this affects the diffusing capacity of the lung to carbon monoxide (DLCO). Eleven patients had measurements of DLCO and specific diffusing capacity (DLCO/VA) before and after sclerotherapy. In ten of these patients sclerotherapy was done using sodium morrhuate mixed with 99mTc-labeled albumin microspheres followed by quantitative radionuclide scanning. Most of the sodium morrhuate, 80 +/- 18% (SD) of the total dose, remained in the region of the esophagus. Only 20% of the injected dose reached the pulmonary circulation. There were no changes in DLCO or DLCO/VA. We conclude that most of the sclerosing solution injected during endoscopic variceal sclerotherapy remains at the site of injection. As a result, the pulmonary endothelium is exposed to small amounts of sodium morrhuate and no change in diffusing capacity occurs.

Symptomatic osteoarthritis of the temporomandibular joint: report of a case.

A case of osteoarthritis in the TMJ which manifested clinical symptoms, radiographic changes, and the classic microscopic alterations has been presented. Whether the condition was a primary or secondary form of the disease could not be unequivocally ascertained, as the symptoms preceded the injection of a sclerosing solution and a mandibular fracture, both of which could be significant contributing factors to a trauma-induced secondary osteoarthritic change. Nevertherless, a lack of symptoms in other joints would tend to exclude a generalized (primary) form of osteoarthropathy. In this regard, symptoms referable to the TMJ (to the exclusion of other joints) are more consistent with findings of secondary osteoarthritic change. Whether osteoarthritic changes were discernible by radiography in the TMJ before the traumatic episodes recorded in the history is unknown. Indeed, a developmental anatomic anomaly could not be ruled out. Regardless of whether the changes were the result of primary degenerative disease or chronic trauma, the symptoms were adequately resolved by surgical intervention.

["Interventional radiology" in breast examination].

The data on such highly-effective invasive diagnostico-therapeutic procedures as ductography, sclerosing-solution cystography, X-ray-controled puncture biopsy, stereotactical computer technique, sonography and preoperative maging of nonpalpable lesions were analyzed following a complex mammographic examination of 20,000 patients with different breast pathologies. Advantages offered by complex breast examination are discussed. Among them were the use of optimal effects of each invasive procedure, an accuracy of preoperative diagnosis reaching 95-98% (nonpalpable breast lesions included) and a significantly reduced extent of breast surgery.
