ABSTRACT

Objective To investigate the clinical significance of compensatory angiogenesis and the angiosome-based revascularization strategy for endovascular procedures in treating infrapopliteal critical limb ischemia in elderly diabetic patients.Methods A retrospective study of 194 patients with diabetic feet (Fontaine Ⅳ) who had undergone endovascular procedures at our hospital from January 2005 to December 2014 was performed.Based on the angiosome concept,all subjects were classified into the direct revascularization group (DR group),the indirect revascularization through collaterals group (IR-tc group) and the indirect revascularization without collaterals group (IR-wc group).After one-year follow-up,the therapeutic effects were analyzed and compared between the three groups.Results During the one-year follow-up,the rate of unhealed ulcers,the re-intervention rate and the rate of major adverse limb events (MALE) were higher in the IR-wc group than in the DR and IR-tc groups (P=0.000 and 0.000,P=0.025 and 0.013,P=0.014 and 0.023,respectively).The IR-wc group presented a lower limb salvage rate as compared with those in the DR and IR-tc groups (P=0.011 and 0.027).Patients with a single recanalized branch had a higher rate of unhealed ulcers than those with multiple recanalized branches in the IR-wc group (93.9% vs.71.0%,P=0.015).Conclusions The angiosome-based revascularization strategy has shown important value in guiding endovascular procedures for patients with diabetic foot disease and,in particular,the compensatory angiogenesis approach appears to be critical in generating favorable short-term clinical outcomes in the treatment of diabetic foot disease.

ABSTRACT

<p><b>OBJECTIVE</b>The aim of this study was to evaluate the number of central cervical lymph node metastasis (CCLNM) in predicting lateral cervical lymph node metastasis (LCLNM) in patients with papillary thyroid carcinoma (PTC).</p><p><b>METHODS</b>From January 2005 to October 2010, a total of 133 patients diagnosed as PTC underwent central and lateral cervical lymph node dissection were enrolled in this study. Quantitative analysis was performed to explore the correlation between the number of CCLNM and LCLNM.</p><p><b>RESULTS</b>The sensitivity of central cervical node metastasis to predict lateral cervical node metastasis was 84.7%(61/72), and the positive predictive value (PPV) was 66.3% (61/92). The incidence of lateral cervical LNM was correlated with the number of CCLNM (r=0.911, P=0.004). The LCLNM rates in patients with number of CCLNM <2 and ≥ 2 were 54.5% (12/22) and 70.0% (49/70), respectively, with a non-significant difference (P=0.181). The LCLNM rates in patients with number of CCLNM < 3 and ≥ 3 were 50.0% (19/38) and 77.8% (42/54), showing a significant difference (P=0.006). The LCLNM rates in patients with number of CCLNM <4 and ≥ 4 were 55.1% (27/49) and 79.1% (34/43), with a significant difference (P=0.015). The LCLNM rates in patients with number of CCLNM <5 and ≥ 5 with the LLNM rate were 57.6% (34/59) and 81.8% (27/33), showing a significant difference (P=0.019). The LCLNM rates in patients with number of CCLNM <6 and ≥ 6 were 60.0% (39/65) and 81.5% (22/27), showing a significant difference (P=0.047).</p><p><b>CONCLUSIONS</b>CCLNM has a significant association with LCLNM in patients with papillary thyroid carcinoma. LCLNM is mainly observed in patients with ≥ 3 CCLNM. Therefore, the number of CLNM ≥ 3 may be a valuable predictor of lateral cervical lymph node metastasis, and lateral cervical lymph node dissection should be considered.</p>

ABSTRACT

Objective To find the clinical and histopathological predictive factors for lateral lymph node ( LN ) metastasis in thyroid papillary microcarcinoma( PTMC ).Methods From January 2007 to December 2010,141 patients with PTMC underwent central and lateral LN dissections were enrolled in the study.The data from the cases were analyzed retrospectively to determine the predictive factors for lateral LN metastasis.Results Among the aforementioned cases,37 cases ( 26.2% ) were PTMC with the presence of multifocality,24 ( 16.9% ) Hashimoto thyroiditis,84 ( 59.6% ) central LN metastasis,56 ( 39.7% ) lateral LN metastasis.Multifocality,central LN metastasis,underlying Hashimoto thyroiditis,and upper pole location were significantly related to lateral LN metastasis in univariate analysis( P<0.05 ).These four factors were also found to be independent predictive factors for lateral LN metastasis in multivariate analysis( P<0.05 ).9(6.4% ) of there patients were found to show skip metastasis in which there was lateral LN metastasis but no central LN metastasis.The upper pole location was statistically significantly associated with skip metastasis.Conclusions Patients with multifocality,central LN metastasis,underlying Hashimoto thyroiditis,and upper pole location should be paid more attention to the status of lateral LN.Skip metastasis occurs in a minority of patients with PTMC.Even if there is no central LN metastasis,patients with upper pole lesion should be searched carefully for the lateral cervical LN metastasis.

ABSTRACT

ObjectiveTo probe into the ultrasonic(US) predictive value for metastasis of the cervical lateral lymph node(LNM) with the preoperative ultrasonic examination in thyroid papillary microcarcinoma (PTMC),then,to further evaluate the significance of the preoperative ultrasonic score (US) for predicting metastasis of the cervical lateral lymph node.Methods From May 2004 to May 2011,165 patients diagnosed as PTMC (the ultrasonic imaging of lymph node showed no lateral LNM) were retrospectively analyzed and the US and final pathological data from the cases were collected to determine the relevant factors and different scores.ResultsThere were significant differences(P < 0.05 )among US characteristics of microcalcification,no well-defined margin,tumor located at the upper pole,the perimeter of the tumor contacted with the adjacent capsule of thyroid being >25 % and the presence of the cervical lateral lymph nodes metastasis in PTMC between the metastatic group and the non-metastatic group.The total scores of the ultrasonic ≥2.5 was the delimitation value,its sensitivity was 86.2% and its specificity was 89.7%.ConclusionsThe ultrasonic score has definite value in the differential diagnosis for the metastasis of the cervical lateral node in the patients of no lateral LNM,when the ultrasonic score is larger than 2.5,the possibility of the cervical lateral lymph node metastasis should be noticed.
