RESUMEN

Although percutaneous renal biopsy remains the preferred method, there are several scenarios where transjugular approach is more suitable. We hereby describe our technique of transjugular renal biopsy (TJRB) and evaluate its safety and efficacy. We retrospectively collected data regarding indication for the transjugular route of biopsy, its complications, clinical and laboratory data, and adequacy of samples from patients' records. TJRB was performed when the patients were at a high risk for bleeding from percutaneous renal biopsy. Tissue samples were assessed by a pathologist for adequacy. All patients were followed up with ultrasonographic scan 3 h after the procedure and on day 3. Nine patients (age 41.5 ± 15.4 years; 8 men) underwent 9 TJRB procedures. The procedure was technically successful in all patients. Six patients (66.67%) had a platelet count of <50,000/mcL, 2 (33.3%) had an elevated International Normalized Ratio of more than 1.4, and 1 had both. 3.2 ± 0.4 cores were obtained, with median (range) number of glomeruli being ten (7-11). Adequate renal tissue sample was obtained in all the patients. Though capsular perforation developed in 5 patients, none had major complication requiring management (endovascular treatment or blood transfusion). TJRB is a safe and effective in patients with contraindications to percutaneous biopsy.

RESUMEN

Angiographic appearances are characteristic, distinctive and a major basis of established criteria in the diagnosis of aortoarteritis. We present a pictorial review of digital subtraction angiography imaging in patients with proven aortoarteritis, based upon 16 years' experience in our institution. Understanding of these angiographic appearances is important for definitive diagnosis, and for evaluation of the extent of the disease in order to plan appropriate further management.

RESUMEN

BACKGROUND/AIMS: To assess the incidence of extensive portal and splenic vein thrombosis in patients with extrahepatic portal vein obstruction and determine the differences in presentation, portal hemodynamics and management as compared to patients with portal vein thrombosis alone. METHODOLOGY: 118 patients of extrahepatic portal vein obstruction presenting with variceal hemorrhage, having received no definitive treatment prior to presentation were divided into two groups--with portal and splenic vein thrombosis and with portal vein thrombosis, based on ultrasonography and splenoportography. Collateralization patterns on splenoportography were studied. Results of endoscopic variceal sclerotherapy were compared. RESULTS: Portal and splenic vein thrombosis was seen in 39 patients. Collateralization in case of portal and splenic vein thrombosis, in contrast to portal vein thrombosis, was predominantly left sided (74% vs. 9%, p < 0.0001). Fundal gastric varices were seen more often in patients with portal and splenic vein thrombosis (28% vs. 11%, p = 0.02), developing even after variceal obliteration, though obliteration was achieved in fewer sessions. Surgery for control of variceal bleed was performed more in the portal and splenic vein thrombosis group (33% vs. 15%, p = 0.02), especially for gastric varices (28% vs. 9%, p = 0.006). CONCLUSIONS: Portal and splenic vein thrombosis is present in 33% of patients with extrahepatic portal vein obstruction. Hemodynamic patterns differ, accounting for the preponderance of gastric varices on presentation in patients with portal and splenic vein thrombosis and an increased need for surgery.

RESUMEN

A case of massive rectal bleeding due to colonic tuberculosis in advanced pregnancy with intrauterine foetal death is reported. Patient was treated with resection of the left colon and left transverse end colostomy with closure of the rectal stump. Hysterotomy for the removal of the dead foetus was performed. The patient improved in health with antitubercular treatment. The colorectal anastomosis was performed after 4 months. Massive rectal bleeding in intestinal tuberculosis, though rare should be kept in mind.

RESUMEN

OBJECTIVE: To present the results of surgical lymphorenal disconnection and its advantages in patients with severe chyluria. PATIENTS AND METHODS: Seventy-eight patients (40 men and 38 women, age 22-58 years) with severe chyluria of variable duration (5 months to 14 years), underwent surgical disconnection of the lymphorenal communication after confirming the diagnosis of chyluria by urine examination for fat globules, lymphangiography to delineate the side, site and extent of lymphorenal communication, and cystoscopy to decide the side to be operated. The areolar tissue containing dilated lymphatics travelling to the kidney in the perirenal and hilar region was dissected and divided between ligatures, thus stripping these structures completely; only one side was operated at a time. RESULTS: All 78 patients were available for a minimum follow-up of 1 year, with the longest follow-up 15 years. Lymphangiography showed unilateral communication in 52 (66%) and bilateral in 26 (34%). If the patient was given a high-fat meal before surgery, the intra-operative visualization of the lymphatics was improved. With unilateral surgery, clearance was achieved in 74 (94%) immediately, with final success in 69 (88%) patients. Of the 26 (34%) patients with bilateral lesions, nine (12%) required bilateral surgery, giving a clearance rate of 97%. In two cases of failure, repeat surgery was successful in one; thus the overall success rate was 98%. CONCLUSION: Lymphorenal disconnection for chyluria is simple, successful as a permanent cure and with almost negligible complications. Bilateral lymphorenal communication seen on lymphangiography does not always warrant bilateral surgery.

RESUMEN

PURPOSE: To determine the efficacy of bronchial artery embolization in the control of massive hemoptysis due to pulmonary tuberculosis. MATERIALS AND METHODS: Between 1988 and 1994, 140 patients (125 men and 15 women; mean age, 31.5 years) who presented with massive hemoptysis (more than 300 mL of blood in 24 hours) underwent bronchial artery embolization. Fifty-one patients had received no antituberculosis drugs. Bronchial artery embolization was performed on the side with the greater abnormality on the chest radiograph. Catheters (4 F) and a gelatin sponge were used for embolization. Inflammatory hypervascularity was seen in all patients (five patients had contrast material extravasation and 10 patients had pseudoaneurysms). RESULTS: Almost complete control of hemoptysis was achieved in 102 patients. Of the remaining 38 patients with a notable amount of bleeding after the procedure, 29 were treated successfully with conservative measures and nine underwent re-embolization. Seven patients who underwent re-embolization had recurrent bleeding; four of these patients underwent successful surgery, and three died of aspiration. Two patients developed transient paraparesis 6 hours after the procedure. Nine patients reported transient referred pain to the ipsilateral orbit during injection of the gelatin sponge. One patient had transient dysphagia. CONCLUSION: Patients with massive hemoptysis due to pulmonary tuberculosis should first be treated with bronchial artery embolization.

RESUMEN

OBJECTIVE: To delineate the venographic anatomy of the varicoceles which recur following conventional inguinal varicocele ligation and to determine the therapeutic efficacy of steel-coil embolization as assessed by improvements in seminal parameters and paternity. PATIENTS AND METHODS: Thirty-nine patients with post-surgical recurrent varicoceles underwent bilateral internal spermatic venography approached through the right femoral vein. The collateral venous channels were identified and occluded using appropriate sizes of steel coils. RESULTS: The procedure was technically successful in 33 patients (85%). Analysis of the 33 venograms showed a unilateral left-sided recurrent varicocele in 28 patients (85%) and bilateral recurrent varicoceles in five patients (15%). The mid and lower parallel collateral channels were observed in 27 patients (82%). The recurrences were treated easily with stainless steel-coil embolization. Five patients were lost to follow-up. Of the remaining 28 patients the sperm count and motility became normal in 16 (57%); only the motility improved in three patients (10%) while in nine patients (33%) there were no changes in either of the seminal parameters. Five patients achieved paternity. CONCLUSIONS: Internal spermatic venography allowed a precise anatomical definition of the recurrent varicocele and the use of steel-coil embolization provided satisfactory improvements in sperm quality and paternity.

RESUMEN

Forty patients with symptoms of neuro-vascular compression in the upper extremities were subjected to impedance plethysmographic study using Parulkar's method. Two patients recorded decreased blood flow (BFI) in supine position and were diagnosed as having partial occlusion at subclavian level. Sixteen of the patients recorded decreased BFI on 90 degrees abduction and hyper-abduction. Twelve of these patients had radiological evidence of anomalous cervicle ribs. In remaining four patients extrinsic impression on the subclavian artery due to fibrous deposits was confirmed by arteriography. Remaining 22 patients recorded normal impedance plethysmograms. Impedance plethysmography thus provided a non-invasive modality for confirmation of vascular compression in thoracic outlet syndrome.

RESUMEN

Impedance plethysmography (IPG) was carried out in one hundred and forty-one patients suspected of venous disorders using Parulkar's method. In these patients occlusive impedance phlebography (OIP) and venography were also carried out using standard procedures. Comparison of IPG and OIP observations with venographic findings revealed sensitivity of these methods to be 65% and 77.7% in the diagnosis of primary varicosity of veins and chronic deep vein thrombosis respectively with a specificity of 85%. Occlusive impedance phlebograms showing unilateral decrease in OIP parameters were observed to be sufficiently diagnostic. IPG observations in 5 patients with arterio-venous malformation were observed to be different from those in patients with deep vein thrombosis.
