[Hepatic phlebography before and after portacaval anastomosis].

Wedged hepatic venography has been utilized in the hemodynamic staging of portal hypertension in 33 patients. The immediate postoperative evaluation in 18 cases, has outlined a portal vein filling in 14 end-to-side portacaval shunts, in 5 with presence of hepatofugal collateral veins between the ligated hepatic and shunted splanchnic sides of the portal system, and in 2 side-to-side. The sinusoidal filling pattern has been relatively unchanged after end-to-side portacaval shunts. The venographic appearance of "spontaneous" reversal of portal blood flow in hepatic cirrhosis must be confirmed by selective hepatic arteriography before affirming its presence.

[Aorto-iliac reconstructions].

The Authors refer their retrospective experience on 80 aorto-iliac reconstructions in 76 patients with a follow-up of 39.6 months (6-84). The patients have been classified in 6 functional classes and in 4 angiographic groups. The overall postoperative mortality has been 5.0% and the cumulative patency rate at five years 87.7%. Better functional results whether immediate or late in patients class C and group I.

[Occlusions of the subrenal abdominal aorta].

Personal surgical experience with 14 cases of total occlusion of the abdominal aorta is presented. In 11 cases the revascularization has been performed with thrombectomy from below and bifurcated aortic prothesis. In 5 cases of infrarenal aortic occlusion the thrombectomy has been accomplished with only temporary digital suprarenal compression. The postoperative mortality has been nil. No temporary or definitive renal complications.

Sentinel node and radioguided surgery in breast cancer of limited size. Preliminary experience at ASL 1, Massa e Carrara.

The aim of this study was to evaluate the effectiveness of sentinel node (SN) biopsy in breast cancer. Twenty-five female patients classified as T1N0 according to the TNM system of the UICC were evaluated with this procedure from April to October 1999. The day before surgery a subdermal injection of 99mTc-nanocoll within the tissue overlying the neoplastic lesion and subsequent lymphoscintigraphy were performed. In all patients the SN was detected with a radioguided probe during scintigraphy and surgery. Histological examination of the SN for detection of metastases was positive in four patients who subsequently underwent axillary dissection. In the remaining patients with normal SNs no axillary dissection was performed. The preliminary results confirm the validity of the sentinel node procedure.
