40-Year-Male with Chest Pain for evaluation detected to have Absent Left Circumflex Artery
: 3-D Volume rendered CT Coronary Angiography Images showing Absent Left Circumflex Artery
(c) The main branch stent balloon was inflated, which jailed the side branch semi-inflated balloon in the intermediate branch and the Corsair Pro microcatheter in the left circumflex artery
. (d) Blood flow was preserved in both side branches after stenting.
The rate of traumatic arthritis in femoral head fracture-dislocation is 24% and it will increase when concomitant acetabulum fracture, unanatomical reduction and delayed reduction.8 The femoral head necrosis may be related to time from injury to surgery, original or iatrogenic injury of medial femoral circumflex artery
. We believed that in order to avoid the femoral head necrosis in a maximum degree, the reduction operation should be taken as early as possible.
Myocardial infarction due to left circumflex artery
LCx occlusion has been less studied in trials regarding ST elevation MI; this is mainly due to the absence of significant ST segment elevation on ECG.
Supplementary Video 1: Left coronary angiography demonstrating severe stenosis of the left circumflex artery
and CTO of the LAD.
Main coronary arteries selected are RCA, LAD artery and circumflex artery
On the 8[sup]th day after admission, coronary angiography (CAG) was performed to evaluate coronary vasculature, showing mild stenosis in right coronary artery, whereas 50–60% stenosis in left anterior descending artery (LAD) and chronic occlusion of distal left circumflex artery
Left main coronary artery stenosis area larger than 50% and left anterior descending branch, left circumflex artery
and right coronary artery stenosis area larger than 75% were taken as the evaluation criteria; large branches such as diagonal branch, obtuse marginal branch and right ventricular branch were attributed to left anterior descending branch, left circumflex artery
and right coronary artery.
Anterior, inferior and lateral myocardial infarction was seen in 128 (64%), 67 (33.5%) and 5 (2.5%) patients respectively.Left anterior descending (LAD) was the commonest culprit artery in 128 (64%) followed by right coronary artery (RCA) and left circumflex artery
(LCX) in 57 (28.5%) and 15 (7.5%) cases respectively.
For example, during the placement of posterior portals, risks of injuring the posterior humeral circumflex artery
(Naidoo et al, 2014), the circumflex artery
of the scapula (Ebraheim et al, 2010), the suprascapular nerve (Bigliani et al., 1990; Shishido & Kikuchi, 2001; Gumina et al., 2011), branches of the infraspinous artery (Naidoo et al.), and muscle vessels that provide irrigation to the joint capsule have been documented (Andary & Petersen, 2002).
Selective coronary artery angiography was performed to rule out ischemic heart disease and demonstrated a large, tortuous vessel arising from the circumflex artery
and bifid (Y) origin of the right coronary artery (Fig.
The mid and distal segments of the right coronary artery were 100%, left circumflex artery
was 70-80% and left anterior decending artery was 70-90% occluded.
