Evaluating Coronary–Cameral Fistulas

Evaluating Coronary-Cameral Fistulas.

To the Editor: Having read the interesting case report by Banerjee and Patra1 in the August 2016 issue of the Journal, we wish to contribute to their discussion on coronary–cameral fistulas (CCFs). Acquired CCFs may be iatrogenic or post-traumatic. For a CCF to be classified as acquired, it must not have been present at birth, it must not have been seen on prior angiographic images, and its cau...

Rectovaginal fistulas.

[Pancreatic fistulas].

Based on 17 observations the authors review the major etiopathogenic, evolutive, clinical and therapeutic aspects of pancreatic fistulae. In 14 cases the cure was achieved by medical treatment while surgery was resorted to in only three cases. The medical measures are discussed, as well as the indications for surgical treatment.

Spinal Arteriovenous Fistulas

Several classifications have been proposed for spinal AVMs.[2],[4]-[6] They can be divided into intramedullary AVMs and arteriovenous fistulas (AVFs). Based on anatomical characteristics, spinal AVFs are classified as extradural AVFs and intradural lesions, including spinal dural AVFs (SDAVFs) and perimedullary spinal AVFs (PMAVFs).[7],[8] Rangel-Castilla et al. classified extradural AVFs as ty...

Congenital Arteriovenous Fistulas

Arteriovenous fistulas of the thoracic wall may produce murmurs and thrills which suggest an intrathoracic vascular abnormality. Congenital arteriovenous fistulas in the plecordial region, the site of the fistula in the case here reported, may be confused with anomalies of the heart and great vessels. The differential diagnosis of blood vessel tumors of the chest wall is discussed. Occasionally...
