Pseudoaneurysm of the superficial temporal artery following penetrating trauma.

Pseudoaneurysm of superficial temporal artery (STA) is an uncommon complication of blunt and penetrating trauma. It accounts for only 1% of all traumatic aneurysms. Most pseudoaneurysms of STA present as a painless pulsating mass, and its diagnosis can be made with physical examination and ultrasound or computed tomography angiogram.

Preoperative ⁹⁹mTc-sestamibi scintigraphy in patients with primary hyperparathyroidism and concomitant nodular goiter: comparison of SPECT-CT, SPECT, and planar imaging.

Background: Investigations using a hybrid single photon emission computed tomography/computed tomography (SPECT-CT) scanning technique have been carried out in limited studies and have shown mixed results. However, the assessment of this technique for the detection of parathyroid adenoma in patients with a nodular goiter was performed in only one study with a small sample size. The aim of this prospective study was to assess the role of 99mTc-sestamibi parathyroid SPECT-CT scans for localization of parathyroid adenomas with a concomitant nodular goiter using 99mTc-methoxyisobutyl isonitrile (MIBI) scintigraphy and to compare it with SPECT and planar imaging.

Allograft en bloc vagino-utero-ovarian avascular transplant versus autograft implantation in rats.

Objectives: The aim of this study was to compare the results of an allograft en bloc vagino-uteroovarian avascular transplant with those of autograft implantation in rats.

Materials And Methods: Thirty-four inbred adult virgin female Albino rats (age range, 10 - 12 weeks) were divided into 2 groups: the control group (autograft, n=11) and the study group (en bloc vagino-utero-ovariectomy, n=23). In the study group, the uterus and adnexa and the ovaries of the donor rat were transplanted to the recipient animal.

Treatment of infected pseudoaneurysm in drug abusers: ligation or reconstruction?

Background: Recently, there has been an increase in the incidence of major vascular complications such as infected pseudoaneurysm due to intravenous drug use.

Objective: For better understanding of the existing controversies regarding the optimal surgical management of infected pseudoaneurysm, the present study was conducted.

Methods: Medical charts of 36 consecutive patients who underwent surgery in Taleghani Hospital, Tehran, Iran from 1996 through 2003, were retrospectively analyzed.
