Off-pump versus on-pump coronary artery bypass surgery in high-risk patients (EuroSCORE >/= 6).

OBJECTIVE: The aim of this study was to review the results of off-pump (OPCAB) versus conventional on-pump coronary artery bypass surgery (CCAB) in high-risk patients. METHODS: In a cohort of patients with an additive EuroSCORE >/= 6, 67 underwent OPCAB and 112 underwent CCAB. RESULTS: Thirty-day postoperative death and stroke rates were 7.5 % and 6.0 % for the OPCAB group, and 5.4 % ( P = 0.75) and 8.0 % ( P = 0.77) for the CCAB group, respectively. No significant differences were observed for other major outcome endpoints other than cardiac troponin I (OPCAB: 117 +/- 428 ng/ml vs. CCAB: 58 +/- 99 ng/ml, P = 0.028), a result which was probably due to preoperative massive myocardial infarction in two very high-risk patients who underwent OPCAB. A similar outcome was also observed among propensity score-matched pairs. Congestive heart failure ( P = 0.006, OR: 6.366, 95 % CI: 1.682 - 24.093) and baseline cardiac index ( P = 0.018, OR: 0.171, 95 % CI: 0.040 - 0.735) were independent predictors of 30-day postoperative mortality. CONCLUSIONS: OPCAB can be safely performed in high-risk patients with results as satisfactory as those achieved with CCAB.

Staged endovascular stent-grafting and surgical treatment of a secondary aortoduodenal fistula.

Secondary aortoenteric fistula is a dramatic, rather infrequent late complication occurring mostly after abdominal aortic surgery. Currently, graft excision and in situ bypass is considered the treatment of choice, but it is associated with significant mortality and morbidity. Herein, we describe the case of a secondary aortoduodenal fistula treated by staged endovascular stent-grafting and surgical closure of the fistula. Forty days after stent-grafting, Tc-99m-HMPAO labelled leukocyte scanning failed to identify leukocyte infiltration of the graft and there were no clinical signs of infection. At 8-month follow up, the patient was asymptomatic.

[Surgical treatment of varicocele in day surgery]. / Il trattamento chirurgico del varicocele in day surgery.

Aim of this study is the comparison between spermatic vein ligature (Ivanissevich technique) and low intrafunicular ligature in the surgical treatment of varicocele. The Authors present two groups of patients (total 61) operated between 1995 and 1999 with the above-mentioned surgical techniques. Apart from the utilized method, they didn't ascertain any improvements in the spermiograms of the patients older than 30 years. The low ligature of the spermatic veins demonstrated the advantages of surgery treatment and lower percentage of relapses.

[Extracorporeal shock wave lithotripsy in the treatment of sialolithiasis. Long-term results]. / La litotrissia extracorporea ad onde d'urto nella terapia della scialolitiasi. Risultati a distanza.

The Authors report the results of a short term follow-up in 28 patients treated for sialolithiasis. Extracorporeal lithotripsy is safe, effective and minimally invasive therapeutical option. Open surgery is reserved to cases of failure of noninvasive procedure.

[Familial papillary carcinoma of the thyroid: biogenetic identification and clinical assessment of 4 families]. / Il carcinoma papillifero della tiroide a carattere familiare: determinazioni biogenetiche e valutazioni cliniche su quattro gruppi familiari.

The Authors report 9 patients who were affected by familial papillary carcinoma of thyroid These patients were members of 4 families and they were selected in a general group of 97 patients affected by papillary cancer of the thyroid who underwent surgery from 1991 to 1998. The 9 patients were 1st degree relatives: two sisters, two sisters, two sisters and three brothers. The clinical course was similar in patients whether familiar or sporadic group, but average age in first was 10 yrs lower than in the latter group. Functional cervical dissection was needed only one time by lymphatic metastasis. Observed survival was 100% (follow up 92-16 months) and no specific complication was reported. Thyreoglobulin value was less than normal in every patients. Ret linkage analysis was always performed and no rearrangement was found; in 4 patients APC gene was detected but it was never seen. Case studies are consistent with an autosomal dominant trait that shows an high penetrance if associated with a permissive codominant trait. The authors believe that are necessary further studies on this occurrence. In papillary thyroid cancer familiarity was observed in 9.6%, than authors propose that relatives of thyroid papillary cancer should be underwent to screening.

Familial papillary carcinoma of the thyroid: a report of nine first-degree relatives of four families.

The authors report the occurrence of papillary carcinoma of the thyroid in nine first-degree relatives of four families among a consecutive series of 97 patients with papillary carcinoma of the thyroid who were operated on from 1991 to 1998. Total thyroidectomy was performed in all cases. All patients are alive without evidence of disease after a mean follow-up period of 43 months. Since in our series familial papillary carcinoma of the thyroid was found in 9.3% of patients, we suggest an adequate screening among first-degree relatives of all patients with papillary thyroid carcinoma. Because of reported aggressive behaviour of familial papillary carcinoma of the thyroid, aggressive surgical treatment plus post-operative thyroid remnant ablation with radio-iodine should be warranted in all patients.

[The inferior nonrecurrent laryngeal nerve: a report of 7 cases observed since 1987]. / Il nervo laringeo inferiore non ricorrente: descrizione di 7 casi osservati dal 1987.

The non-recurrent inferior laryngeal nerve is a rare anomaly (0.34% on th right side, extremely rare on the left side) that increases the risk of damage to the nerve during thyroid and parathyroid surgery. Seven cases of non-recurrent laryngeal nerve are reported, emphasizing the diagnostic accuracy of angio-MR for the anatomical identification of the vascular anomaly that invariably occurs with the nerve malformation.

[Monomorphic adenomas of the parotid gland: description of 3 clinical cases]. / Gli adenomi monomorfi della parotide: descrizione di tre casi clinici.

Three cases of monomorphic adenomas (two oncocytic adenomas and one basal cell adenoma) of the parotid gland are reported. The diagnosis is based on echography with fine needle biopsy and cervical computerized tomography. Because of the high percentages of multicentricity, the therapy of choice is superficial parotidectomy when the lesion is in the pre-neural lobe of the gland, or total parotidectomy in case of a deep mass.
