The blood supply of the isthmus
also has some variability: it may receive blood from the main renal artery, from the abdominal aorta (originating above or below the isthmus
), the common iliac artery or the inferior mesenteric artery (Mano et al., 2016).
Europaeus-Ayrapaa presented in his work a three-part classification for the pottery of the Stone Age from Finland and the Karelian Isthmus
. The system includes Early (Ka I or Sperrings), Typical (Ka II or TCW) and Late Comb Ware (Ka III or LCW).
Various locations of the base of pyramidal lobe generally require careful dissection of both the pretracheal and the prelaryngeal regions from the upper border of the isthmus
up to the upper border of the thyroid cartilage in most of the patients and sometimes up to the hyoid bone.
Long-term outcomes after catheter ablation of cavo-tricuspid isthmus
dependent atrial flutter: a metaanalysis.
Although the incidence of thyroid isthmus
agenesis has been reported to range between 0.5% and 10%, the precise incidence rate is unknown (4, 5).
* Graft isthmus
artery: End-to-end anastomosis to the recipient internal iliac artery.
With regard to unfilled parts of the root canal system, an unfilled isthmus
(27.5%), an unfilled main canal (18.8%) or an unfilled isthmus
with unfilled canals (11.5%) were the main findings (Table 3).
The clinical causes of failure were categorized as follows: (1) leaky canal: a gap between the previous root filling and the dentin or obvious leakage after methylene blue staining; (2) anatomical complexity: isthmus
between the two canals filled or an apical ramification that had not been treated; (3) missing canal: untreated canal regardless of the presence of an isthmus
; (4) underfilling: fillings more than 2 mm short of the apex in preoperative radiographs; (5) over-filling: excess root filling; (6) iatrogenic problem: perforation, transportation, or file separation; (7) calcified canal; and (8) calculus.
A hard lump of size 20 x 15 mm and unclear border could be seen on the isthmus
of thyroid during surgery.
The winners of the categories 12.6 and 14 will have the unique opportunity to travel for free with Aegean Airlines and take part in the final race of the Seventh Hellenic SUP CUP 2017, the crossing of Isthmus
The 337-km highway and the rail line for the Ferrocarril del Sureste in the Isthmus
of Tehuantepec are part of the Mexican government's grand plan to improve the country's transportation infrastructure, including port facilities.
The association between RAI treatment failure and various clinical parameters including age, sex, height, weight, body mass index (BMI), thyroid gland volume, and isthmus
length on ultrasonographic images, thyroid function and thyroid autoantibody levels before treatment, dose of RAI, RAI uptake rate, and serum selenium and 25-hydroxycholecalciferol levels was analyzed.
