Objective: Endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) is a safe and an effective treatment for varicose veins caused by saphenous reflux. Deep venous thrombosis (DVT) and endovenous heat-induced thrombosis (EHIT) are known complications of these procedures. The purpose of this article is to investigate the incidence of postoperative DVT and EHIT in patients undergoing EVLA and RFA. Methods: The patients were assessed by clinical examination and venous duplex ultrasonography before operation and at 24–72 hours, 1 month, and 1 year follow-up after operation. Endovenous ablation had been treated for 1,026 limbs (835 patients) using an RFA; 1,174 limbs (954 patients) using a 1,470-nm wavelength diode laser with radial 2 rings fiber (1,470R); and 6,118 limbs (5,513 patients) using a 980-nm wavelength diode laser with bare-tip fiber (980B). Results: DVT was detected in 3 legs (0.3%) of RFA, 5 legs (0.4%) of 1,470R, and 27 legs (0.4%) of 980B. One patient in three symptomatic DVT treated with 980B developed asymptomatic pulmonary embolus. Thirty-one of the 35 DVTs were confined to the calf veins. The incidence of EHIT classes 2–3 was 2.7% following RFA procedure, 6.7% after 1470R, and 7.5% after 980B. Conclusion: The incidence of EHIT following endovenous ablation was low, especially the RFA procedure. EHIT resolves within 2–4 weeks in most patients. DVT rates after endovenous ablation compared with those published for saphenous vein stripping.
We describe a case of a 37-year-old male who suffered catheterization-induced arterial aneurysm and arteriovenous fistula formation in the radial artery. The size of the aneurysm was 3.6×2.9 mm and the arteriovenous fistula had been formed between the radial artery and one of its accompanying veins. Ligation of the accompanying vein, aneurysmectomy, and angioplasty of the radial artery with an end-to-end anastomosis technique were performed on day-surgery basis. This surgery was finished successfully without any problems. It is necessary to consider the possibilities of these iatrogenic complications when examining puncture sites after catheterization.
A 30-year-old male had LMT stenosis and AAE, secondary to aortitis syndrome. He was given a CABG and aortic root replacement operation. After the surgery, he continued taking internal steroids. Twelve years later, CT scan results showed that coronary artery stenosis has disappeared. Now, 16 years after the surgery, along with regression of inflammation, intimal proliferation has been improved. His heart function is in good condition, and there has been no need for another surgery. From our observation, the key factors for decent long-term results were operational ideas and the use of steroids for controlled inflammation.
We performed aortic aneurysm repair in a 64-year-old man who had undergone renal transplantation at 28 years of age. Abdominal computed tomography demonstrated abdominal aortic aneurysm, right common iliac artery aneurysm, and internal iliac artery aneurysm. During aortic clamping, the transplanted kidney was perfused with 4°C Ringer’s solution by direct cannulation to the donor renal ar tery. Aor tic revascularization was accomplished with a trifurcated graft. He made a good recovery without postoperative deterioration on renal function.
