Surgical management of ascending saphenous thrombophlebitis.

BACKGROUND: Acute saphenous vein ascending thrombophlebitis is recognised to be a dangerous condition due to the reported high incidence of deep vein thrombus involvement and possibly fatal pulmonary embolism. We assessed the accuracy of duplex scanning in determining the extent of thrombosis as well as the effectiveness of surgical treatment. METHODS: We retrospectively reviewed 146 patients referred to our Vascular Laboratory for acute superficial thrombophlebitis from 1987 to 1997. Duplex scanning identified 85 cases of superficial thrombophlebitis involving at least a segment of the saphenous vein localised below the knee (58.2%); 37 of thrombophlebitis extending into both the superficial and deep venous systems (25.3%), and 24 of saphenous thrombosis extending to within 5 cm of the saphenofemoral junction (16.4%). The latter group underwent saphenofemoral disconnection. We compared the preoperative duplex with the surgical reports and evaluated the surgical results. RESULTS: We did not observe any complication. Return to work and normal activity occurred within 3-5 days. When varicose vein thrombectomy was performed concurrently, the patients had better postoperative pain control. CONCLUSIONS: Duplex scanning showed 100% accuracy both in determining the presence of thrombosis and its extent. Saphenofemoral disconnection for thrombosis involving the saphenofemoral junction is a safe procedure and can be performed on an outpatient basis.

[New directions in the surgical treatment of gastroesophageal reflux. Review of the literature]. / Nuovi orientamenti nel trattamento chirurgico della patologia da reflusso gastroesofageo. Revisione della letteratura.

The pathophysiology of gastroesophageal reflux disease (GERD) is often multifactorial, as abnormal function of the lower esophageal sphincter (LES) may be associated to abnormalities of the esophageal peristalsis, the esophageal clearance, and the gastric reservoir. The preoperative evaluation of patients with GERD must include esophageal function tests (esophageal manometry and ambulatory pH monitoring) and evaluation of the gastric emptying in addition to UGI series and endoscopy. The information provided by these tests is essential to identify the pathophysiology of the disease in the individual patient, and tailor the operative treatment accordingly. For patients with an incompetent LES but normal esophageal peristalsis, the Nissen fundoplication is the procedure of choice. When abnormal peristalsis and delayed clearance are identified by preoperative esophageal function tests, a partial fundoplication must be chosen in order to avoid postoperative dysphagia and gas bloat syndrome. Too many eponyms have been used to describe antireflux surgery (Nissen, Rossetti, Toupet, Lind, Hill, Guarner). It is time to go beyond these eponyms, and focus on the technical details which contribute to the stability of the wrap, as this is the main determinant of long term outcome.

[Video-assisted venous surgery]. / La chirurgia venosa videoassistita.

The use of intraoperative angioscopy, till now utilized exclusively in arterial surgery, is now used also in venous surgery. From January 1992 54 patients underwent to video-guided venous surgery: 23 cases of external valvuloplasty of the sapheno-femoral junction (EV-SFJ), 25 cases of hemodynamic correction of varicose veins (French acronyms CHIVA), 5 cases of high ligation plus long saphenous vein intraoperative sclerotherapy (HL-IS) 1 case of sub-fascial perforators interruption (SPI), the only extraluminal videoguided procedure. We have used 3 different video-angioscopes: a 1 mm monofibroscopy let in a 6 Fr Fogarty catheter, a disposable 2,8 mm colangioscope and a 2,2 mm operative angioscope. For the perforators interruption we have utilised the thoracoscope. EV-SFJ: the angioscopy has confirmed the presence of normal valvular cusps in a dilated vein wall in 21 cases, so excluding 2 patients from the planned treatment. At the end of the operation the angioscope has verified the reapproach of valvular cusps. CHIVA: the angioscopy has allowed to identify the exact points of the superficial venous system which should be interrupted, according to the Franceschi's theory. This procedure can avoid the technical errors due to intraoperatory misleadings of the duplex mapping. HL-IS: consists of a classic high ligation followed by long saphenous vein intraoperative sclerotherapy. The angioscopy has allowed a complete deconnection of the long saphenous vein from tributaries and perforators. Furthermore has facilitate the proportional distribution of the sclerosing agent along the long saphenous vein. SPI: the videoassistance have permitted the identification of the insufficient perforating veins reducing their surgical exposures.(ABSTRACT TRUNCATED AT 250 WORDS)

[Clinical and hemodynamic effects of external valvuloplasty of the sapheno-femoral junction]. / Effetti clinici ed emodinamici della plastica esterna delle valvole del giunto safeno-femorale.

Selected patients with primary varicose vein disease and sapheno-femoral reflux as the only point of regurgitation in the affected lower limb and duplex evidence of mobile valve leaflets underwent external valvuloplasty of the sapheno-femoral junction. Operations were performed under local anesthesia in one day-surgery. One PTFE sleeve 0.4 mm thick, in average 1.2 cm long and able to uncircle a circumference in average of 1.7 cm was put around the terminal Long Saphenous vein valve, located in the last centimeter of this vein. If also the subterminal Long Saphenous Vein valve site, located 5 cm below is dilated a second valvuloplasty was performed. In 15 case we used intra-operatory video-angioscopy guide. This examination allowed us to exclude two patients with valve damages not duplex demonstrable. Furthermore angioscopy permitted immediate demonstration of restored valvular function. Follow-up lasted on average 48 months: two early postoperative long saphenous vein thrombosis, and two late sapheno-femoral reflux recurrences were the main complications. We never observed graft infection. AVP was reduced and RT, measured by the means of LRR, had a prolongation after surgery. Both measurements had an highly significant difference from a statistical point of view, comparing pre and postoperative values. 95% of the operated patients have stable varices reduction. Long Saphenous Vein patency was recorded in 37 cases (92.5%). On the contrary, after high ligation, the fate of the saphenous vein in 21% of case is the occlusion. Symptoms of venous insufficiency disappeared completely in 80% of cases and improved in 95% of the operated patients.(ABSTRACT TRUNCATED AT 250 WORDS)
