This study demonstrated that the outcomes of endovascular treatment for TASC C and D aorto-iliac lesions were acceptable, with better technical success in TASC C lesions than in TASC D lesions. Furthermore, the 2-year patency rate for both TASC C and TASC D lesions was acceptable. Additionally, brachial access was useful for complex anatomy, but the failure rate was high.

This prospective study surveyed the prevalence of peripheral arterial disease (PAD) in Korean patients with coronary arterial disease (CAD) or cerebrovascular disorder (CVD). From March 2010, 576 hospitalized patients in cardiovascular or stroke center were enrolled as the study group. Ankle-brachial index (ABI) was measured and the cut-off point for diagnosing PAD was ≤ 0.9 at rest. A total of 424 hospitalized patients in the Department of Surgery and aged ≥ 50 yr was enrolled as the control gr

Coronary steal after ipsilateral AVF creation in patients with CABG using in situ internal thoracic artery (ITA) developed in 12%, which can be related to low LVEF. In patients with CABG requiring AVF for hemodialysis, the ipsilateral fistula to the grafted ITA should be carefully selected and performed.

Pharmacological prophylaxis after KT is not necessary because of the low incidence of DVT in Korean patients, and instead, we suggest that long-term mechanical prophylaxis of at least 3 months can be a suitable option. Patients older than 50 years of age have a higher risk of developing DVT, and careful observation is needed in these patients.

The history of cancer in AAA patients increases long-term mortality but does not affect short-term mortality after AAA repair. However, AAA repair could increase both short- and long-term mortality in patients with lung cancer history, and those cases should be more carefully selected.

This study has shown that the adequate positioning of RFA catheter tip (2.0-2.5 cm) is recommended to decrease the incidence of EHIT.

Patients aged < 20 years had more rapid disease progression to end-stage renal disease and a higher recurrence rate after transplant than patients aged ≥ 20 years. If patients aged ≥ 20 years progress rapidly from progressive symptoms to renal replacement therapy, renal transplant may be considered after 24 months because of high recurrence risk.

Our study shows that when the needle is inserted at the apex of the anatomical triangle directed towards the ipsilateral nipple, it crosses the IJV at 16°. Since the common carotid artery is usually medial to the IJV, directing the needle towards the ipsilateral nipple seems to be a safe way to avoid the common carotid artery and successfully puncture the IJV.

This study was conducted to investigate the effects of erythropoietin (Epo) on both acute and chronic limb ischemia (ALI and CLI) and to evaluate the differences in mechanisms according to the method of Epo administration. Hindlimb ischemia was made in BALB/c mice with femoral artery ligation. The mice were divided into four groups: Group 1 (control, no treatment), Group 2 (ALI, early multiple doses), Group 3 (ALI, early single high dose), Group 4 (CLI, late multiple doses).

Our long-term analysis on oncologic aspects confirms the safety of LLR compared to OLR in HCC patients.
